1. Philosophy / E. Nature of Metaphysics / 1. Nature of Metaphysics
I don't think Lewis's cost-benefit reflective equilibrium approach offers enough guidance [Stalnaker]
     Full Idea: Lewis articulated and made fashionable the cost-benefit reflective equilibrium methodology, but I have my reservations as it does not offer much guidance.
     From: Robert C. Stalnaker (Mere Possibilities [2012], 1.1)
     A reaction: Stalnaker suggests that this approach has 'run amok' in Lewis's case, giving reality to possible worlds. He spends much effort on showing the 'benefits' of a profoundly implausible view. The same can be said of 4D Perdurantism.
1. Philosophy / F. Analytic Philosophy / 5. Linguistic Analysis
The best way to do ontology is to make sense of our normal talk [Davidson]
     Full Idea: I do not know any better way of showing what there is than looking at the assumptions needed to make sense of our normal talk.
     From: Donald Davidson (Causal Relations [1967], §4)
     A reaction: Davidson was a pupil of Quine. This I take to be the last flowering of twentieth century linguistic philosophy. The ontology we deduce from talk in a children's playground might be very bizarre, but we are unlikely to endorse it. 'Honest, it's true!'
2. Reason / A. Nature of Reason / 5. Objectivity
Objective truth arises from interpersonal communication [Davidson]
     Full Idea: The source of the concept of objective truth is interpersonal communication.
     From: Donald Davidson (Three Varieties of Knowledge [1991], p.209)
     A reaction: This is a distinctively Davidsonian idea, arising out of Wittgenstein's Private Language Argument. We could go a step further, and just say that 'objectivity is a social concept'. Davidson more or less pleads guilty to pragmatism in this essay.
There are no ultimate standards of rationality, since we only assess others by our own standard [Davidson]
     Full Idea: It makes no sense to speak of comparing or agreeing on ultimate standards of rationality, since it is our own standards in each case to which we must turn in interpreting others. This is not a failure of objectivity, but where 'questions come to an end'.
     From: Donald Davidson (Davidson on himself [1994], p.232)
     A reaction: This seems wrong, given the commitment to truth and charity in interpretation. He could have said the same about perception, but I doubt if he would.
Truth and objectivity depend on a community of speakers to interpret what they mean [Davidson]
     Full Idea: The basis on which the concepts of truth and objectivity depend for application is a community of understanding, agreement among speakers on how each is to be understood.
     From: Donald Davidson (Davidson on himself [1994], p.233)
     A reaction: Obviously all understanding is, in practice, an interpretation by a community, but that isn't what 'truth' means. We mean 'true independently of any community'.
3. Truth / A. Truth Problems / 1. Truth
A sentence is held true because of a combination of meaning and belief [Davidson]
     Full Idea: A sentence is held true because of two factors: what the holder takes the sentence to mean, and what he believes.
     From: Donald Davidson (Thought and Talk [1975], p.20)
     A reaction: A key question is whether a belief (e.g. an imagistic one, or one held by an animal) could be true, even though no sentence is involved. Linguistic philosophers tend to avoid this question, or assume the answer is 'no'.
3. Truth / A. Truth Problems / 2. Defining Truth
Truth cannot be reduced to anything simpler [Davidson]
     Full Idea: We cannot hope to underpin the concept of truth with something more transparent or easier to grasp.
     From: Donald Davidson (The Folly of Trying to Define Truth [1999], p.21)
     A reaction: I suppose precise accounts of correspondence or coherence are offered as replacements for truth, but neither of those ever seem to be possible. I agree with accepting truth as a primitive.
A comprehensive theory of truth probably includes a theory of predication [Davidson]
     Full Idea: Theories of truth and theories of predication are closely related: it seems probable that any comprehensive theory of truth will include a theory of predication.
     From: Donald Davidson (Truth and Predication [2005], 6)
     A reaction: Davidson defends the view that it is this way round. It is tempting to label them both as 'primitive'. Davidson distinguishes a 'theory' about truth from a 'definition'.
3. Truth / A. Truth Problems / 3. Value of Truth
Plato's Forms confused truth with the most eminent truths, so only Truth itself is completely true [Davidson]
     Full Idea: Plato's conflation of abstract universals with entities of supreme value reinforced the confusion of truth with the most eminent truths. …The only perfect exemplar of a Form is the Form itself, …and only truth itself is completely true.
     From: Donald Davidson (Truth Rehabilitated [1997], p.3)
     A reaction: Even non-subscribers to Plato often talk as if there were some grand thing called the Truth with a capital T, quite often used in a religious context. Truth is the hallmark of successful (non-fanciful) thought.
Truth can't be a goal, because we can neither recognise it nor confim it [Davidson]
     Full Idea: Since it is neither visible as a target, nor recognisable when achieved, there is no point in calling truth a goal. We should only aim at increasing confidence in our beliefs, by collecting further evidence or checking our calculations.
     From: Donald Davidson (Truth Rehabilitated [1997], P.6)
     A reaction: This is mainly aimed at pragmatists, but Davidson obviously subscribes (as do I) to their fallibilist view of knowledge.
Antirealism about truth prevents its use as an intersubjective standard [Davidson]
     Full Idea: Antirealism, with its limitations of truth to what can be ascertained, deprives truth of its role as an intersubjective standard.
     From: Donald Davidson (Truth and Predication [2005], 2)
     A reaction: I like this, because it lifts truth out of individual minds. I take truth to be an ideal - a simple one with little content, which is thus fairly uncontroversial. Truth is the main general purpose of thinking.
Without truth, both language and thought are impossible [Davidson]
     Full Idea: Without a grasp of the concept of truth, not only language, but thought itself, is impossible.
     From: Donald Davidson (Truth Rehabilitated [1997], p.16)
     A reaction: Davidson never mentions animals, but I like this idea because it points to importance of truth for animals as well. I say that truth is relevant to any mind that makes judgements - and quite small animals (e.g. ants and spiders) make judgements.
3. Truth / A. Truth Problems / 5. Truth Bearers
Davidson takes truth to attach to individual sentences [Davidson, by Dummett]
     Full Idea: Davidson, by contrast to Frege, has taken truth as attaching to linguistic items, that is, to actual or hypothetical token sentences.
     From: report of Donald Davidson (True to the Facts [1969]) by Michael Dummett - Truth and the Past 1
     A reaction: My personal notion of truth is potentially applicable to animals, so this doesn't appeal to me. I am happy to think of animals as believing simple propositions that never get as far as language, and being right or wrong about them.
3. Truth / A. Truth Problems / 8. Subjective Truth
'Epistemic' truth depends what rational creatures can verify [Davidson]
     Full Idea: The 'epistemic' view of truth asserts an essential tie to epistemology, and introduces a dependence of truth on what can somehow be verified by finite rational creatures.
     From: Donald Davidson (Truth and Predication [2005], 2)
     A reaction: This view, which seems to be widely held, strikes me as an elementary confusion. I take truth to be fully successful belief. If you say belief can never be fully successful, then we can't know the truth - but that doesn't destroy the concept of truth.
3. Truth / B. Truthmakers / 12. Rejecting Truthmakers
Saying truths fit experience adds nothing to truth; nothing makes sentences true [Davidson]
     Full Idea: The notion of fitting the totality of experience ...adds nothing intelligible to the simple concept of being true. ....Nothing, ...no thing, makes sentences and theories true: not experience, not surface irritations, not the world.
     From: Donald Davidson (The Very Idea of a Conceptual Scheme [1974], p.11), quoted by Willard Quine - On the Very Idea of a Third Dogma p.39
     A reaction: If you don't have a concept of what normally makes a sentence true, I don't see how you go about distinguishing what is true from what is false. You can't just examine the sentence to see if it has the 'primitive' property of truth. Holism is involved....
3. Truth / C. Correspondence Truth / 1. Correspondence Truth
Names, descriptions and predicates refer to things; without that, language and thought are baffling [Davidson]
     Full Idea: The simple thesis that names and descriptions often refer to things, and that predicates often have an extension in the world of things, is obvious, and essential to the most elementary appreciation of both language and the thoughts we express.
     From: Donald Davidson (Replies to Critics [1998], p.323)
     A reaction: In 1983 Davidson had been a rare modern champion of the coherence theory of truth, but this is his clearest later renunciation of that view (and quite right too).
Correspondence can't be defined, but it shows how truth depends on the world [Davidson]
     Full Idea: Correspondence, while it is empty as a definition, does capture the thought that truth depends on how the world is.
     From: Donald Davidson (Truth Rehabilitated [1997], p.16)
     A reaction: Just don't try to give a precise account of the correspondence between two things (thoughts and facts) which are so utterly different in character.
3. Truth / C. Correspondence Truth / 3. Correspondence Truth critique
Correspondence theories can't tell you what truths correspond to [Davidson]
     Full Idea: The real objection to correspondence theories is that such theories fail to provide entities to which truth vehicles (as statements, sentence, or utterances) can be said to correspond.
     From: Donald Davidson (The Structure and Content of Truth [1990], p.304), quoted by Fred Sommers - Intellectual Autobiography Notes 23
     A reaction: This is the remark which provoked Sommers to come out with Idea 18901, which strikes me as rather profound.
Neither Aristotle nor Tarski introduce the facts needed for a correspondence theory [Davidson]
     Full Idea: Neither Aristotle's formula nor Tarski's truth definitions are sympathetic to the correspondence theory, because they don't introduce entities like facts or states of affairs for sentences to correspond.
     From: Donald Davidson (The Folly of Trying to Define Truth [1999], p.25)
     A reaction: This seems convincing, although it is often claimed that both theories offer a sort of correspondence.
There is nothing interesting or instructive for truths to correspond to [Davidson]
     Full Idea: The real objection to the correspondence theory of truth is that there is nothing interesting or instructive to which true sentences correspond. (C.I. Lewis challenged defenders to locate the fact or part of reality to which a truth corresponded).
     From: Donald Davidson (Truth and Predication [2005], 2)
     A reaction: Davidson defended a correspondence view in 'True to the Facts'. Davidson evidently also thinks the same objection applies to claims about truthmakers. If you say 'gold is shiny', the gold is very dispersed, but it is still there.
The Slingshot assumes substitutions give logical equivalence, and thus identical correspondence [Davidson]
     Full Idea: The Slingshot argument (of Frege, Church and Gödel) assumes that if two sentences are logically equivalent, they correspond to the same thing, and what a sentence corresponds to is not changed if a singular term is replaced by a coreferring term.
     From: Donald Davidson (Truth and Predication [2005], 6)
     A reaction: This obviously won't work for 'Oedipus thinks he ought to marry Jocasta'. Sentences correspond, I presume, to what they are about, which is often a matter of emphasis or phrasing. Hence the Slingshot sounds like nonsense to me.
Two sentences can be rephrased by equivalent substitutions to correspond to the same thing [Davidson]
     Full Idea: Slingshot: 'Scott is the author of Waverley' and 'The number of counties in Utah is twenty-nine' can be rephrased by substitution so that they are both about the number twenty-nine, and are thus correspond to the same thing.
     From: Donald Davidson (Truth and Predication [2005], 6)
     A reaction: [my paraphrase of Davidson's quote from Church 1956:24] These sentences clearly do not correspond to the same thing, so something has gone wrong with the idea that logically equivalent sentences have identical correspondents.
3. Truth / D. Coherence Truth / 1. Coherence Truth
Coherence with a set of propositions suggests we can know the proposition corresponds [Davidson, by Donnellan]
     Full Idea: Davidson argues that the coherence of a set of propositions with a set of beliefs is a good indication that the proposition corresponds to objective facts and that we can know that propositions correspond.
     From: report of Donald Davidson (Coherence Theory of Truth and Knowledge [1983]) by Keith Donnellan - Putting Humpty Dumpty Together Again §2.2
     A reaction: Young calls this an 'epistemological route to coherentism'. Davidson is sometimes cited as a fan of the coherence theory of truth, but this just seems to accept Russell's point that coherence is a good test for truth.
Coherence truth says a consistent set of sentences is true - which ties truth to belief [Davidson]
     Full Idea: A pure coherence theory of truth says that all sentences in a consistent set of sentences are true. ...I class this with epistemic views, because it ties truth directly to what is believed.
     From: Donald Davidson (Truth and Predication [2005], 2)
     A reaction: [He cites Neurath] I would have thought that coherence is rather more than mere consistency. Truths which have nothing whatever in common can be consistent with one another. [but see his p.43 n14]
3. Truth / F. Semantic Truth / 1. Tarski's Truth / b. Satisfaction and truth
We can explain truth in terms of satisfaction - but also explain satisfaction in terms of truth [Davidson]
     Full Idea: Truth is easily defined in terms of satisfaction (as Tarski showed), but, alternatively, satisfaction can be taken to be whatever relation yields a correct account of truth.
     From: Donald Davidson (Truth and Predication [2005], 2)
     A reaction: Davidson is assessing which is the prior 'primitive' concept, and he votes for truth. A perennial problem in philosophy, and very hard to find reasons for a preference. The axiomatic approach grows from taking truth as primitive. Axioms for satisfaction?
Satisfaction is a sort of reference, so maybe we can define truth in terms of reference? [Davidson]
     Full Idea: That the truth of sentences is defined by appeal to the semantic properties of words suggests that, if we could give an account of the semantic properties of words (essentially, of reference or satisfaction), we would understand the concept of truth.
     From: Donald Davidson (Truth and Predication [2005], 2)
     A reaction: If you thought that words were prior to sentences, this might be the route to go. Davidson gives priority to sentences, and so prefers to work from the other end, which treats truth as primitive, and then defines reference and meaning.
Axioms spell out sentence satisfaction. With no free variables, all sequences satisfy the truths [Davidson]
     Full Idea: Axioms specify how each unstructured predicate is satisfied by a particular sequence. Then recursive axioms characterise complex sentences built from simpler ones. Closed sentences have no free variables, so true sentences are satisfied by all sequences.
     From: Donald Davidson (Truth and Predication [2005], 7)
     A reaction: I take 'all sequences' to mean all combinations of objects in the domain. Thus nothing in domain contradicts the satisfied sentences. Hence Tarski's truth is said to be 'true in a model', where the whole system vouches for the sentence.
3. Truth / F. Semantic Truth / 1. Tarski's Truth / c. Meta-language for truth
When Tarski defines truth for different languages, how do we know it is a single concept? [Davidson]
     Full Idea: We have to wonder how we know that it is some single concept which Tarski indicates how to define for each of a number of well-behaved languages.
     From: Donald Davidson (Truth Rehabilitated [1997], P.11)
     A reaction: Davidson says that Tarski makes the assumption that it is a single concept, but fails to demonstrate the fact. This resembles Frege's Julius Caesar problem - of how you know whether your number definition has defined a number.
The language to define truth needs a finite vocabulary, to make the definition finite [Davidson]
     Full Idea: If the definition of the truth predicate is to be finite (Tarski insisted on this), the definition must take advantage of the fact that sentences, though potentially infinite in number, are constructed from a finite vocabulary.
     From: Donald Davidson (The Folly of Trying to Define Truth [1999], p.23)
     A reaction: Not sure whether this is in the object language or the meta-language, though I guess the former.
3. Truth / F. Semantic Truth / 2. Semantic Truth
Many say that Tarski's definitions fail to connect truth to meaning [Davidson]
     Full Idea: It is complained that Tarski's definitions do not establish the connection between truth and meaning that many philosophers hold to be essential.
     From: Donald Davidson (Truth and Predication [2005], 1)
     A reaction: This, of course, was Davidson's big mission - to build on Tarski's theory a view of truth which dovetailed it with theories of meaning and reference.
Tarski does not tell us what his various truth predicates have in common [Davidson]
     Full Idea: There is no indication in Tarski's formal work of what it is that his various truth predicates have in common, and this is part of the content of the concept.
     From: Donald Davidson (Truth and Predication [2005], 1)
     A reaction: This seems like a good question to raise. If I list all the 'red' things, I can still ask what qualifies them to all appear on the same list.
Truth is the basic concept, because Convention-T is agreed to fix the truths of a language [Davidson]
     Full Idea: The key role of Convention-T in determining that truth, as characterised by the theory, has the same extension as the intuitive concept of truth makes it seem that it is truth rather than reference that is the basic primitive.
     From: Donald Davidson (Truth and Predication [2005], 2)
     A reaction: The key strength of Tarski's account is that it specifies the extension of 'true' for a given language (as expressed in a richer meta-language).
To define a class of true sentences is to stipulate a possible language [Davidson]
     Full Idea: When we enquire whether a truth definition defines the class of true sentences in a particular language, we are thinking of the truth definition as stipulating a possible language.
     From: Donald Davidson (Truth and Predication [2005], 7)
     A reaction: Thus I might say "Nij wonk yang" is true if and only if snow is white, and make my first step towards a new language. An interesting way of looking at Tarski's project.
3. Truth / G. Axiomatic Truth / 1. Axiomatic Truth
We can elucidate indefinable truth, but showing its relation to other concepts [Davidson]
     Full Idea: We can still say revealing things about truth, by relating it to other concepts like belief, desire, cause and action.
     From: Donald Davidson (The Folly of Trying to Define Truth [1999], p.21)
     A reaction: The trickiest concept to link it to is meaning. I think Davidson's view points to the Axiomatic account of truth, which flourished soon after Davidson wrote this. We can give rules for the correct use of 'true'.
3. Truth / H. Deflationary Truth / 1. Redundant Truth
Truth is basic and clear, so don't try to replace it with something simpler [Davidson]
     Full Idea: Truth is one of the clearest and most basic concepts we have, so it is fruitless to dream of eliminating it in favor of something simpler or more fundamental.
     From: Donald Davidson (Truth and Predication [2005], 3)
     A reaction: For redundancy theorists, I suppose, truth would be eliminated in favour of 'assertion'. Replacing it with 'satisfaction' doesn't seem very illuminating. Davidson would say 'reference' is more tricky and elusive than truth.
3. Truth / H. Deflationary Truth / 2. Deflationary Truth
Disquotation only accounts for truth if the metalanguage contains the object language [Davidson]
     Full Idea: Disquotation cannot pretend to give a complete account of the concept of truth, since it works only in the special case where the metalanguage contains the object language. Neither can contain their own truth predicate.
     From: Donald Davidson (Truth Rehabilitated [1997], p.10)
     A reaction: Presumably more sophisticated and complete accounts would need a further account of translation between languages - which explains Quine's interest in that topic. […see this essay, p.12]
Tarski is not a disquotationalist, because you can assign truth to a sentence you can't quote [Davidson]
     Full Idea: It is clearly a mistake to call Tarski a disquotationalist. ...We say of a sentence not at hand (such as 'You gave the right answer to this question last night, but I can't remember what you said') that it is true or false.
     From: Donald Davidson (Truth and Predication [2005], 7)
4. Formal Logic / D. Modal Logic ML / 3. Modal Logic Systems / a. Systems of modal logic
Non-S5 can talk of contingent or necessary necessities [Stalnaker]
     Full Idea: One can make sense of necessary versus contingent necessities in a non-S5 modal semantics.
     From: Robert C. Stalnaker (Mere Possibilities [2012], 4.3 n17)
     A reaction: In S5 □φ → □□φ, so all necessities are necessary. Does it make any sense to say 'I suppose this might have been necessarily true'?
4. Formal Logic / D. Modal Logic ML / 7. Barcan Formula
To say there could have been people who don't exist, but deny those possible things, rejects Barcan [Stalnaker, by Rumfitt]
     Full Idea: Stalnaker holds that there could have been people who do not actually exist, but he denies that there are things that could have been those people. That is, he denies the unrestricted validity of the Barcan Formula.
     From: report of Robert C. Stalnaker (Counterparts and Identity [1987]) by Ian Rumfitt - The Boundary Stones of Thought 6.2
     A reaction: And quite right too, I should have thought. As they say, Jack Kennedy and Marilyn Monroe might have had a child, but the idea that we should accept some entity which might have been that child but wasn't sounds like nonsense. Except as fiction…..
4. Formal Logic / F. Set Theory ST / 4. Axioms for Sets / b. Axiom of Extensionality I
In modal set theory, sets only exist in a possible world if that world contains all of its members [Stalnaker]
     Full Idea: One principle of modal set theory should be uncontroversial: a set exists in a given possible world if and only if all of its members exist at that world.
     From: Robert C. Stalnaker (Mere Possibilities [2012], 2.4)
     A reaction: Does this mean there can be no set containing all of my ancestors and future descendants? In no world can we coexist.
5. Theory of Logic / C. Ontology of Logic / 1. Ontology of Logic
Logical space is abstracted from the actual world [Stalnaker]
     Full Idea: Logical space is not given independently of the individuals that occupy it, but is abstracted from the world as we find it.
     From: Robert C. Stalnaker (Anti-essentialism [1979], p.85)
     A reaction: I very much like the second half of this idea, and am delighted to find Stalnaker endorsing it. I take the logical connectives to be descriptions of how things behave, at a high level of generality.
5. Theory of Logic / E. Structures of Logic / 1. Logical Form
We regiment to get semantic structure, for evaluating arguments, and understanding complexities [Stalnaker]
     Full Idea: The point of regimentation is to give a perspicuous representation of the semantic structure of an expression, making it easier to evaluate the validity of arguments and to interpret complex statements.
     From: Robert C. Stalnaker (Mere Possibilities [2012], 4.2)
     A reaction: This is an authoritative summary from an expert of why all philosophers must take an interest in logical form.
There is a huge range of sentences of which we do not know the logical form [Davidson]
     Full Idea: We do not know the logical form of sentences about counterfactuals, probabilities, causal relations, belief, perception, intention, purposeful action, imperatives, optatives, or interrogatives, or the role of adverbs, adjectives or mass terms.
     From: Donald Davidson (Truth and Meaning [1967], p.35)
     A reaction: [compressed] This is the famous 'Davidson programme', where teams of philosophers work out the logical forms for this lot, thus unravelling the logic of the world. If they are beavering away, some sort of overview should have emerged by now...
5. Theory of Logic / E. Structures of Logic / 2. Logical Connectives / e. or
In 'S was F or some other than S was F', the disjuncts need S, but the whole disjunction doesn't [Stalnaker]
     Full Idea: In 'either Socrates was a philosopher or someone other than Socrates was a philosopher', both propositions expressed by the disjuncts depend for their existence on the existence of Socrates, but the whole disjunction does not.
     From: Robert C. Stalnaker (Mere Possibilities [2012], 4.2)
     A reaction: Nice example, just the sort of thing we pay philosophers to come up with. He is claiming that propositions can exist in possible worlds in which the individuals mentioned do not exist.
5. Theory of Logic / F. Referring in Logic / 1. Naming / c. Names as referential
To understand a name (unlike a description) picking the thing out is sufficient? [Stalnaker]
     Full Idea: If we ask 'what must you know to understand a name?', the naïve answer is that one must know who or what it names - nothing more. (But no one would give this answer about what is needed to understand a definite description).
     From: Robert C. Stalnaker (Reference and Necessity [1997], 4)
     A reaction: Presumably this is naive because names can be full of meaning ('the Empress'), or description and reference together ('there's the man who robbed me') and so on. It's a nice starting point though. A number can serve as a name.
5. Theory of Logic / G. Quantification / 2. Domain of Quantification
Davidson controversially proposed to quantify over events [Davidson, by Engelbretsen]
     Full Idea: An alternative, and still controversial, extension of first-order logic is due to Donald Davidson, who allows for quantification over events.
     From: report of Donald Davidson (The Individuation of Events [1969]) by George Engelbretsen - Trees, Terms and Truth 3
     A reaction: I'm suddenly thinking this is quite an attractive proposal. We need to quantify over facts, or states of affairs, or events, or some such thing, to talk about the world properly. Objects, predicates and sets/parts is too sparse. I like facts.
5. Theory of Logic / I. Semantics of Logic / 4. Satisfaction
'Satisfaction' is a generalised form of reference [Davidson]
     Full Idea: We can think of 'satisfaction' as a generalised form of reference.
     From: Donald Davidson (Truth and Predication [2005], 2)
     A reaction: Just the sort of simple point we novices need from the great minds, to help us see what is going on. One day someone is going to explain Tarski's account of truth in plain English, but probably not in my lifetime.
7. Existence / A. Nature of Existence / 1. Nature of Existence
Some say what exists must do so, and nothing else could possible exist [Stalnaker]
     Full Idea: Some philosophers deny there could have been anything other than what in fact exists, or that anything that exists could have failed to exist. This is developed in very different ways by Wittgenstein (in 'Tractatus'), Lewis and Williamson.
     From: Robert C. Stalnaker (Mere Possibilities [2012], 1)
     A reaction: This could come in various strengths. A weak version would say that, empirically, that all talk of what doesn't exist is vacuous. A strong necessity (Williamson?) that totally rules out other possible existence is a very odd view.
A nominalist view says existence is having spatio-temporal location [Stalnaker]
     Full Idea: A nominalist definition of existence is 'having spatio-temporal location'.
     From: Robert C. Stalnaker (Mere Possibilities [2012], 1.1)
     A reaction: This would evidently be physicalist as well as nominalist. Presumably it fits the 'mosaic' of reality Lewis refers to. I find this view sympathetic. A process of abstraction is required to get the rest of the stuff we talk about.
7. Existence / B. Change in Existence / 4. Events / a. Nature of events
We need 'events' to explain adverbs, which are adjectival predicates of events [Davidson, by Lycan]
     Full Idea: To deal with the truth conditions for some adverbs, Davidson introduced a domain of 'events', and made adverbs into adjectival predicates of events.
     From: report of Donald Davidson (The Logical Form of Action Sentences [1967]) by William Lycan - Philosophy of Language Ch.9
     A reaction: This seems to be a striking case of a procedure of which I heartily disapprove - deriving you ontology from your semantics. Do all languages have adverbs?
Language-learning is not good enough evidence for the existence of events [Yablo on Davidson]
     Full Idea: One needs a better reason for believing in events than the help they provide with language-learning.
     From: comment on Donald Davidson (The Logical Form of Action Sentences [1967], §8) by Stephen Yablo - Apriority and Existence §8
     A reaction: I can almost believe in micro-events at the quantum level, but I cannot believe that the Renaissance (made of events within events within events) is an event, even though I may 'quantify over it', and discuss its causes and effects.
7. Existence / B. Change in Existence / 4. Events / b. Events as primitive
Varied descriptions of an event will explain varied behaviour relating to it [Davidson, by Macdonald,C]
     Full Idea: Davidson points out that we can only make sense of patterns of behaviour such as excuses if events can have more than one description. So I flip the light switch, turn on the light, illuminate the room, and alert a prowler, but I do only one thing.
     From: report of Donald Davidson (Action, Reasons and Causes [1963]) by Cynthia Macdonald - Varieties of Things Ch.5
     A reaction: We can distinguish an event as an actual object, and as an intentional object. We can probably individuate intentional events quite well (according to our interests), but actual 'events' seem to flow into one another and overlap.
If we don't assume that events exist, we cannot make sense of our common talk [Davidson]
     Full Idea: The assumption, ontological and metaphysical, that there are events, is one without which we cannot make sense of much of our most common talk.
     From: Donald Davidson (Causal Relations [1967], §4)
     A reaction: He considers events to be unanalysable basics. Explanation of normal talk also needs ghosts, premonitions, telepathy and Father Christmas. It is extremely hard to individuate events, unless they are subatomic, and rather numerous.
You can't identify events by causes and effects, as the event needs to be known first [Dummett on Davidson]
     Full Idea: Davidson's criterion for the identity of events is a mistake, because we cannot know the causes and effects of an event until we know what that event comprises.
     From: comment on Donald Davidson (The Individuation of Events [1969]) by Michael Dummett - Frege philosophy of mathematics Ch.10
     A reaction: How many attempts by analytical philosophers to give necessary and sufficient conditions for things seem to founder in this way. Their predecessor is at the end of 'Theaetetus'; you have to know what the sun is before you can define it.
Events can only be individuated causally [Davidson, by Schaffer,J]
     Full Idea: Davidson claims that events can only be individuated causally.
     From: report of Donald Davidson (The Individuation of Events [1969], 3) by Jonathan Schaffer - Causation and Laws of Nature 3
     A reaction: Schaffer rejects this in favour of individuating events by their spatiotemporal locations and intrinsic natures (which seem to be property instantiations, a la Kim). Schaffer was a pupil of David Lewis.
We need events for action statements, causal statements, explanation, mind-and-body, and adverbs [Davidson, by Bourne]
     Full Idea: Davidson claims that we require the existence of events in order to make sense of a) action statements, b) causal statements, c) explanation, d) the mind-body problem, and e) the logic of adverbial modification.
     From: report of Donald Davidson (The Individuation of Events [1969], Intro IIb) by Craig Bourne - A Future for Presentism
     A reaction: Events are a nice shorthand, but I don't like them in a serious ontology. Prior says there objects and what happens to them; Kim reduces events to other things. Processes are more clearly individuated than events.
7. Existence / B. Change in Existence / 4. Events / c. Reduction of events
The claim that events are individuated by their causal relations to other events is circular [Lowe on Davidson]
     Full Idea: Davidson has urged that events are individuated by the causal relations which they bear to one another, in accordance with the principle that events are identical just in case they have the same causes and effects. But the principle is viciously circular.
     From: comment on Donald Davidson (The Individuation of Events [1969]) by E.J. Lowe - The Possibility of Metaphysics 7.4
     A reaction: You wouldn't want to identify a person just by their relationships, even though those will certainly be unique. Generally it is what I am (right now) naming as the Functional Fallacy: believing that specifying the function of x explains x.
7. Existence / D. Theories of Reality / 8. Facts / e. Facts rejected
If we try to identify facts precisely, they all melt into one (as the Slingshot Argument proves) [Davidson]
     Full Idea: If we try to provide a serious semantics for reference to facts, we discover that they melt into one; there is no telling them apart. The relevant argument (the 'Slingshot') was credited to Frege by Alonso Church.
     From: Donald Davidson (Truth Rehabilitated [1997], p.5)
     A reaction: This sounds like good grounds for not attempting to be too precise. 'There are bluebells in my local wood' identifies a fact by words, but even an animal can distinguish this fact. Only a logician dreams of making its content precise.
7. Existence / D. Theories of Reality / 11. Ontological Commitment / d. Commitment of theories
If the best theory of adverbs refers to events, then our ontology should include events [Davidson, by Sider]
     Full Idea: Davidson argued that the best linguistic theory of adverbial modification assigns truth-conditions quantifying over events; thus we must embrace an ontology of events.
     From: report of Donald Davidson (The Logical Form of Action Sentences [1967]) by Theodore Sider - Writing the Book of the World 07.8
     A reaction: Sider is critical and I agree. This is just the sort of linguistic manoeuvre that gets philosophy a bad name. As Yablo remarks, we have a terrible tendency to want to thingify everything.
8. Modes of Existence / B. Properties / 1. Nature of Properties
Properties are modal, involving possible situations where they are exemplified [Stalnaker]
     Full Idea: I take properties and relations to be modal notions. Properties are to be understood in terms of what it would be for them to be exemplified, which means understanding them in terms of a range of possible situations.
     From: Robert C. Stalnaker (Mere Possibilities [2012], 1.2)
     A reaction: I can't make head or tail of a property as anything other than a feature of some entity. Treating properties as a 'range of situations' is just as baffling to me as treating them as sets of objects.
8. Modes of Existence / B. Properties / 10. Properties as Predicates
I accept a hierarchy of properties of properties of properties [Stalnaker]
     Full Idea: I myself am prepared to accept higher-order properties and relations. There is the property of being Socrates, …and the property of being the property of being Socrates, ..and so on.
     From: Robert C. Stalnaker (Mere Possibilities [2012], 4.4)
     A reaction: Elsewhere I have quoted such a hierarchy of vacuous properties as an absurdity that arises if all predicates are treated as properties. Logicians can live with such stuff, given their set hierarchy and so on, but in science and life this is a nonsense.
8. Modes of Existence / B. Properties / 11. Properties as Sets
Treating predicates as sets drops the predicate for a new predicate 'is a member of', which is no help [Davidson]
     Full Idea: 'Theaetetus is a member of the set of seated objects' doesn't mention the predicate 'sits', but has a new predicate 'is a member of', with no given semantic role. We are back with Plato's problem with the predicate 'instantiates'.
     From: Donald Davidson (Truth and Predication [2005], 7)
     A reaction: Plato's problem is the 'third man' problem - a regress in the explanation. In other words, if we are trying to explain predication, treating predicates as sets gets us nowhere. Just as I always thought. But you have to want explanations.
8. Modes of Existence / C. Powers and Dispositions / 6. Dispositions / a. Dispositions
Dispositions have modal properties, of which properties things would have counterfactually [Stalnaker]
     Full Idea: Dispositional properties deserve special mention since they seem to be properties that have modal consequences - consequences for what properties the individuals that instantiate them would have in counterfactual circumstances.
     From: Robert C. Stalnaker (Mere Possibilities [2012], 3.4)
     A reaction: I take this to be the key idea in trying to understand modality, but Stalnaker makes this point and then moves swiftly on, because it is so far away from his possible worlds models, in which he has invested a lifetime.
9. Objects / A. Existence of Objects / 4. Impossible objects
Predicates can't apply to what doesn't exist [Stalnaker]
     Full Idea: Nothing can be predicated of something which does not exist.
     From: Robert C. Stalnaker (Merely Possible Propositions [2010], p.28)
     A reaction: [He says he is 'agreeing with Plantinga' on this] This seems very puzzling, as you can obviously say that dragons do not exist, but they breathe fire. Why can't you attach predicates to hypothetical objects?
9. Objects / C. Structure of Objects / 7. Substratum
For the bare particular view, properties must be features, not just groups of objects [Stalnaker]
     Full Idea: If we are to make sense of the bare particular theory, a property must be not just a rule for grouping individuals, but a feature of individuals in virtue of which they may be grouped.
     From: Robert C. Stalnaker (Anti-essentialism [1979], p.76)
     A reaction: He is offering an objection to the thoroughly extensional account of properties that is found in standard possible worlds semantics. Quite right too. We can't give up on the common sense notion of a property.
Possible worlds allow separating all the properties, without hitting a bare particular [Stalnaker]
     Full Idea: The possible worlds framework suggests a way to express the idea that a particular is conceptually separable from its properties without relying on the rejected picture of a bare particular.
     From: Robert C. Stalnaker (Reference and Necessity [1997], 5)
     A reaction: As I read him, Stalnaker's proposal just comes down to replacing each property in turn with a different one. 'Strip away' red by making it green. It being green in w1 doesn't throw extra light. Can it be a bare particular in w37?
9. Objects / D. Essence of Objects / 7. Essence and Necessity / a. Essence as necessary properties
An essential property is one had in all the possible worlds where a thing exists [Stalnaker]
     Full Idea: If necessity is explained in terms of possible worlds, ...then an essential property is a property that a thing has in all possible worlds in which it exists.
     From: Robert C. Stalnaker (Anti-essentialism [1979], p.71)
     A reaction: This seems to me to be a quite shocking confusion of necessary properties with essential properties. The point is that utterly trivial properties can be necessary, but in no way part of the real essence of something.
'Socrates is essentially human' seems to say nothing could be Socrates if it was not human [Stalnaker]
     Full Idea: It seems natural to paraphrase the claim that Socrates is essentially human as the claim that nothing could be Socrates if it was not human.
     From: Robert C. Stalnaker (Mere Possibilities [2012], 4.3)
     A reaction: In ordinary speech it would be emphasising how very human Socrates was (in comparison with Frege, for example). By this token Socrates essentially breathes oxygen, but that is hardly part of his essence.
9. Objects / D. Essence of Objects / 7. Essence and Necessity / b. Essence not necessities
Necessarily self-identical, or being what it is, or its world-indexed properties, aren't essential [Stalnaker]
     Full Idea: We can remain anti-essentialist while allowing some necessary properties: those essential to everything (self-identity), relational properties (being what it is), and world-indexed properties (being snub-nosed-only-in-Kronos).
     From: Robert C. Stalnaker (Anti-essentialism [1979], p.73)
     A reaction: [a summary] He defined essential properties as necessary properties (Idea 12761), and now backpeddles. World-indexed properties are an invention of Plantinga, as essential properties to don't limit individuals. But they are necessary, not essential!
9. Objects / D. Essence of Objects / 15. Against Essentialism
Bare particular anti-essentialism makes no sense within modal logic semantics [Stalnaker]
     Full Idea: I argue that one cannot make semantical sense out of bare particular anti-essentialism within the framework of standard semantics for modal logic.
     From: Robert C. Stalnaker (Anti-essentialism [1979], p.71)
     A reaction: Stalnaker characterises the bare particular view as ANTI-essentialist, because he has defined essence in terms of necessary properties. The bare particular seems to allow the possibility of Aristotle being a poached egg.
9. Objects / F. Identity among Objects / 7. Indiscernible Objects
The bundle theory makes the identity of indiscernibles a necessity, since the thing is the properties [Stalnaker]
     Full Idea: On the bundle theory, the identity of indiscernibles (for 'individuals') is a necessary truth, since an individual is just the co-instantiation of all the properties represented by a point in the space of properties.
     From: Robert C. Stalnaker (Mere Possibilities [2012], 3.6)
     A reaction: So much the worse for the bundle theory, I presume. Leibniz did not, I think, hold a bundle theory, but his belief in the identity of indiscernibles seems to have had a theologicial underpinning.
10. Modality / A. Necessity / 3. Types of Necessity
Strong necessity is always true; weak necessity is cannot be false [Stalnaker]
     Full Idea: Prior had a strong and a weak reading of necessity, where strong necessity is truth in all possible worlds, while weak necessity is falsity in no possible world.
     From: Robert C. Stalnaker (Mere Possibilities [2012], 4.3)
     A reaction: [K.Fine 2005:Ch.9 is also cited] The point of the weak one is that in some worlds there might not exist the proposition which is the candidate for truth or falsehood.
10. Modality / B. Possibility / 6. Probability
Probability can be constrained by axioms, but that leaves open its truth nature [Davidson]
     Full Idea: Kolmogorov's axiomatisation of probability puts clear constraints on the concept of probability, but leaves open whether probability is further characterised as relative frequency, degree of belief, or something else.
     From: Donald Davidson (Truth and Predication [2005], 2)
     A reaction: Davidson cites this to show the limitations of axiomatic approaches to any topic (e.g. sets, truth, arithmetic). The item in question must be treated as a 'primitive'. This always has the feeling of second-best.
10. Modality / B. Possibility / 8. Conditionals / a. Conditionals
In nearby worlds where A is true, 'if A,B' is true or false if B is true or false [Stalnaker]
     Full Idea: Consider a possible world in which A is true and otherwise differs minimally from the actual world. 'If A, then B' is true (false) just in case B is true (false) in that possible world.
     From: Robert C. Stalnaker (A Theory of Conditionals [1968], p.34), quoted by Dorothy Edgington - Conditionals (Stanf) 4.1
     A reaction: This is the first proposal to give a possible worlds semantics for conditional statements. Edgington observes that worlds which are nearby for me may not be nearby for you.
10. Modality / B. Possibility / 8. Conditionals / d. Non-truthfunction conditionals
Conditionals are true if minimal revision of the antecedent verifies the consequent [Stalnaker, by Read]
     Full Idea: Stalnaker proposes that a conditional is true if its consequent is true in the minimal revision in which the antecedent is true, that is, in the most similar possible world in which the antecedent is true.
     From: report of Robert C. Stalnaker (works [1970]) by Stephen Read - Thinking About Logic Ch.3
     A reaction: A similar account of counterfactuals was taken up by Lewis to give a (rather dubious) account of causation.
10. Modality / C. Sources of Modality / 2. Necessity as Primitive
Necessity and possibility are fundamental, and there can be no reductive analysis of them [Stalnaker]
     Full Idea: My view is that if there were a nonmodal analysis of the modal concepts, that would be a sure sign that we were on the wrong track. Necessity and possibility are fundamental concepts, like truth and existence.
     From: Robert C. Stalnaker (Mere Possibilities [2012], 1.1)
     A reaction: The mystery of modality is tied up with the mystery of time (which is a very big mystery indeed). You get a nice clear grip on the here and now, but time and motion whisk you away to something else. Modality concerns the something else.
10. Modality / C. Sources of Modality / 4. Necessity from Concepts
The necessity of a proposition concerns reality, not our words or concepts [Stalnaker]
     Full Idea: The necessity or contingency of a proposition has nothing to do with our concepts or the meanings of our words. The possibilities would have been the same even if we had never conceived of them.
     From: Robert C. Stalnaker (Conceptual truth and metaphysical necessity [2003], 1)
     A reaction: This sounds in need of qualification, since some of the propositions will be explicitly about words and concepts. Still, I like this idea.
Conceptual possibilities are metaphysical possibilities we can conceive of [Stalnaker]
     Full Idea: Conceptual possibilities are just (metaphysical) possibilities that we can conceive of.
     From: Robert C. Stalnaker (Conceptual truth and metaphysical necessity [2003], 1)
10. Modality / C. Sources of Modality / 5. Modality from Actuality
Modal concepts are central to the actual world, and shouldn't need extravagant metaphysics [Stalnaker]
     Full Idea: Modal concepts are central to our understanding of the world - the actual world - and understanding them should not require extravagant metaphysical commitments.
     From: Robert C. Stalnaker (Mere Possibilities [2012], 1)
     A reaction: I agree. Personally I think powers and dispositions do the job nicely. You just have to embrace Leibniz's emphasis on the active nature of reality, and the implausible metaphysics starts to recede.
10. Modality / D. Knowledge of Modality / 3. A Posteriori Necessary
Critics say there are just an a priori necessary part, and an a posteriori contingent part [Stalnaker]
     Full Idea: Critics say there are no irreducible a posteriori truths. They can be factored into a part that is necessary, but knowable a priori through conceptual analysis, and a part knowable only a posteriori, but contingent. 2-D semantics makes this precise.
     From: Robert C. Stalnaker (Conceptual truth and metaphysical necessity [2003], 1)
     A reaction: [Critics are Sidelle, Jackson and Chalmers] Interesting. If gold is necessarily atomic number 79, or it wouldn't be gold, that sounds like an analytic truth about gold. Discovering the 79 wasn't a discovery of a necessity. Stalnaker rejects this idea.
10. Modality / E. Possible worlds / 1. Possible Worlds / a. Possible worlds
If it might be true, it might be true in particular ways, and possible worlds describe such ways [Stalnaker]
     Full Idea: A clarifying assumption is that if something might be true, then it might be true in some particular way. …Possible worlds begin from this, and the assumption that what might be true can be described as how a possibility might be realised.
     From: Robert C. Stalnaker (Reference and Necessity [1997], 2)
     A reaction: This is a leading practitioner giving his best shot at explaining the rationale of the possible worlds approach, addressed to many sceptics. Most sceptics, I think, don't understand the qualifications the practitioners apply to their game.
Possible worlds are ontologically neutral, but a commitment to possibilities remains [Stalnaker]
     Full Idea: I argue for the metaphysical neutrality of the possible worlds framework, but I do not suggest that its use is free of ontological commitment to possibilities (ways things might be, counterfactual situations, possible states of worlds).
     From: Robert C. Stalnaker (Reference and Necessity [1997], 2)
     A reaction: Glad to hear this, as I have always been puzzled at possible aspirations to eliminate modality (such as possibility) by introducing 'possible' worlds. Commitment to possibilities I take to be basic and unavoidable.
A 'centred' world is an ordered triple of world, individual and time [Stalnaker]
     Full Idea: A 'centred' possible world is an ordered triple consisting of a possible world, an individual in the domain of that world, and a time.
     From: Robert C. Stalnaker (Conceptual truth and metaphysical necessity [2003], 2)
Possible worlds allow discussion of modality without controversial modal auxiliaries [Stalnaker]
     Full Idea: The main benefit of the possible worlds move is to permit one to paraphrase modal claims in an extensional language that has quantifiers, but no modal auxiliaries, so the semantic stucture of modal discourse can be discussed without the controversies.
     From: Robert C. Stalnaker (Reference and Necessity [1997], 2)
     A reaction: The strategy introduces the controversy of possible worlds instead, but since they just boil down to collections of objects with properties, classical logic can reign. Possible worlds are one strategy alongside many others.
10. Modality / E. Possible worlds / 1. Possible Worlds / d. Possible worlds actualism
Given actualism, how can there be possible individuals, other than the actual ones? [Stalnaker]
     Full Idea: My main focus is on how, on an actualist interpretation of possible worlds as ways a world might be, one is to account for the possibility that there be individuals other than those that actually exist.
     From: Robert C. Stalnaker (Mere Possibilities [2012], Pref)
     A reaction: The obvious thought would be that they are constructions from components of actual individuals, such as the chimaera, or fictional characters. We need some psychology here, which is not Stalnaker's style.
10. Modality / E. Possible worlds / 2. Nature of Possible Worlds / a. Nature of possible worlds
A possible world is the ontological analogue of hypothetical beliefs [Stalnaker]
     Full Idea: A possible world is the ontological analogue of a stock of hypothetical beliefs.
     From: Robert C. Stalnaker (A Theory of Conditionals [1968], p.34), quoted by Dorothy Edgington - Conditionals (Stanf) 4.1
     A reaction: Sounds neat and persuasive. What is the ontological analogue of a stock of hopes? Heaven!
We can take 'ways things might have been' as irreducible elements in our ontology [Stalnaker, by Lycan]
     Full Idea: Stalnaker suggests talking 'ways things might have been' as sui generis elements of our ontology - actual abstract entities in their own right, not to be reduced to more familiar items.
     From: report of Robert C. Stalnaker (Possible Worlds [1976]) by William Lycan - The Trouble with Possible Worlds 09
     A reaction: This seems to rest on an ontology of 'states of affairs', favoured by Armstrong, and implied in the Tractatus. How big is a state of affairs? How manys states of affairs can be co-present?
Kripke's possible worlds are methodological, not metaphysical [Stalnaker]
     Full Idea: The possible worlds framework that Kripke introduces should be understood not as a metaphysical theory, but as a methodological framework.
     From: Robert C. Stalnaker (Reference and Necessity [1997], Intro)
     A reaction: That's certainly how I see possible worlds. I lose no sleep over whether they exist. I just take a set of possible worlds to be like cells in a spreadsheet, or records in a database.
Possible worlds are properties [Stalnaker]
     Full Idea: Possible worlds are (to a first approximation) properties. [p.12] They are properties of the total universe.
     From: Robert C. Stalnaker (Mere Possibilities [2012], 1)
Possible worlds don't reduce modality, they regiment it to reveal its structure [Stalnaker]
     Full Idea: It is not reduction (of modality) but regimentation that the possible-worlds framework provides - a procedure for representing modal discourse, using primitive modal notions, in a way that helps reveal its structure.
     From: Robert C. Stalnaker (Mere Possibilities [2012], 1.2)
     A reaction: I think this is exactly my view. All discussion of the ontology of possible worlds is irrelevant. They no more exist than variables in logic exist. They're good when they clarify, but dubious when they over-simplify.
I think of worlds as cells (rather than points) in logical space [Stalnaker]
     Full Idea: I prefer to think of the possible worlds not as points in logical space but as cells of a relatively fine-grained partition of logical space - a partition that makes all the distinctions we need.
     From: Robert C. Stalnaker (Mere Possibilities [2012], 1.2)
     A reaction: Since he regards possible worlds as simply a means of regimenting our understanding of modality, he can think of possible worlds in any way that suits him. I find it hard work tuning in to his vision.
10. Modality / E. Possible worlds / 3. Transworld Objects / a. Transworld identity
Why imagine that Babe Ruth might be a billiard ball; nothing useful could be said about the ball [Stalnaker]
     Full Idea: I cannot think of any point in making the counterfactual supposition that Babe Ruth is a billiard ball; there is nothing I can say about him in that imagined state that I could not just as well say about billiard balls that are not him.
     From: Robert C. Stalnaker (Anti-essentialism [1979], p.79)
     A reaction: A bizarrely circumspect semanticists way of saying that Ruth couldn't possibly be a billiard ball! Would he say the same about a group of old men in wheelchairs, one of whom IS Babe Ruth?
10. Modality / E. Possible worlds / 3. Transworld Objects / b. Rigid designation
Rigid designation seems to presuppose that differing worlds contain the same individuals [Stalnaker]
     Full Idea: A rigid designator is a designator that denotes the same individual in all possible worlds; doesn't this presuppose that the same individuals can be found in differing possible worlds?
     From: Robert C. Stalnaker (Reference and Necessity [1997], 5)
     A reaction: This is part of Stalnaker's claim that Kripke already has a metaphysics in place when he starts on his semantics and his theory of reference. Kripke needs a global domain, not a variable domain. Possibilities suggest variable domains to me.
10. Modality / E. Possible worlds / 3. Transworld Objects / c. Counterparts
Unlike Lewis, I defend an actualist version of counterpart theory [Stalnaker]
     Full Idea: I defend a version of counterpart theory that is quite different from Lewis's version, as it is tied to actualism (all that exists is part of the actual world) rather than possibilism (possible things may exist without actually existing).
     From: Robert C. Stalnaker (Counterparts and Identity [1987], 1)
     A reaction: This could be the theory I am after. I am sympathetic to both actualism and to counterpart theory. Off to the woodshed….
If possible worlds really differ, I can't be in more than one at a time [Stalnaker]
     Full Idea: Nothing can be in two places at once. If other possible worlds are really other universes, then clearly, you and I cannot be in them if we are here in this one.
     From: Robert C. Stalnaker (Counterparts and Identity [1987], 2)
     A reaction: This can be sensibly expressed without possible worlds. I can't embody my other possibilities while I am embodying this one (I'm too busy). Insofar as possible worlds are a good framework, they are just a precise map of common sense.
If counterparts exist strictly in one world only, this seems to be extreme invariant essentialism [Stalnaker]
     Full Idea: Counterparts involve the thesis that domains of different possible worlds are disjoint: possible individuals exist in at most one possible world. This seems to suggest extreme essentialism, where nothing could differ from how it is.
     From: Robert C. Stalnaker (Counterparts and Identity [1987], 2)
     A reaction: He quotes Salmon (1981:236) as saying counterpart theory is particularly inflexible essentialism. This is a long way from my use of 'essentialism'. The problem is just the extent to which my counterpart is 'the same' as me.
Modal properties depend on the choice of a counterpart, which is unconstrained by metaphysics [Stalnaker]
     Full Idea: Things have modal properties only relative to the choice of a counterpart relation, and the choice between alternative counterpart relations is not constrained by the metaphysics.
     From: Robert C. Stalnaker (Mere Possibilities [2012], 3.6)
     A reaction: Stalnaker is sympathetic to counterparts, but this strikes me as a powerful objection to the theory. I take the modal properties of something to be fixed by its actuality.
10. Modality / E. Possible worlds / 3. Transworld Objects / d. Haecceitism
Anti-haecceitism says there is no more to an individual than meeting some qualitative conditions [Stalnaker]
     Full Idea: The anti-haecceitist strategy holds that a purely qualitative characterisation of a possible world would be a complete characterisation; there is, on this view, nothing to being a particular individual other than meeting certain qualitative conditions.
     From: Robert C. Stalnaker (Mere Possibilities [2012], 3)
     A reaction: Not quite the same as the bundle theory of objects, which says the objects are the qualities. This is about individuation, not about ontology (I think). I don't like anti-haecceitism, but I also don't like haecceitism. Hmm.
11. Knowledge Aims / A. Knowledge / 4. Belief / a. Beliefs
Having a belief involves the possibility of being mistaken [Davidson]
     Full Idea: Someone cannot have a belief unless he understands the possibility of being mistaken.
     From: Donald Davidson (Thought and Talk [1975], p.170)
     A reaction: If you pretend to throw a ball for a dog, but don't release it, the dog experiences being mistaken very dramatically.
11. Knowledge Aims / A. Knowledge / 4. Belief / b. Elements of beliefs
The concepts of belief and truth are linked, since beliefs are meant to fit reality [Davidson]
     Full Idea: Knowing what a belief is brings with it the concept of objective truth, for the notion of a belief is the notion of a state that may or may not jibe with reality.
     From: Donald Davidson (Coherence Theory of Truth and Knowledge [1983], p.162)
     A reaction: I find any discussion of belief that makes no reference to truth (as in Hume) quite puzzling. I can understand it when a belief is just triggered by a sensation ('this is hot'), but not when a belief arrives after careful comparison of reasons.
11. Knowledge Aims / A. Knowledge / 4. Belief / e. Belief holism
The concept of belief can only derive from relationship to a speech community [Davidson]
     Full Idea: We have the idea of belief from its role in the interpretation of language; as a private attitude it is not intelligible except in relation to public language. So a creature must be a member of a speech community to have the concept of belief.
     From: Donald Davidson (Thought and Talk [1975], p.22)
     A reaction: This shows how Wittgenstein's Private Language Argument (e.g. Idea 4152) hovers behind Davidson's philosophy. The idea is quite persuasive. A solitary creature just follows its mental states. The question of whether it believes them is a meta-thought.
A belief requires understanding the distinctions of true-and-false, and appearance-and-reality [Davidson]
     Full Idea: Having a belief demands in addition appreciating the contrast between true belief and false, between appearance and reality, mere seeming and being.
     From: Donald Davidson (Three Varieties of Knowledge [1991], p.209)
     A reaction: This sets the bar very high for belief (never mind knowledge), and seems to imply that animals don't have beliefs. How should we describe their cognitive states then? I would say these criteria only apply to actual knowledge.
12. Knowledge Sources / D. Empiricism / 1. Empiricism
Davidson believes experience is non-conceptual, and outside the space of reasons [Davidson, by McDowell]
     Full Idea: Davidson thinks that experience can be nothing but an extra-conceptual impact on sensibility. So he concludes that experience must be outside the space of reasons.
     From: report of Donald Davidson (Coherence Theory of Truth and Knowledge [1983], I.6) by John McDowell - Mind and World I
     A reaction: McDowell's challenge to the view that experience is extra-conceptual seems to be the key debate among modern empiricists. My only intuition in this area is that we should beware of all-or-nothing solutions to such problems.
12. Knowledge Sources / D. Empiricism / 5. Empiricism Critique
Without the dualism of scheme and content, not much is left of empiricism [Davidson]
     Full Idea: The third dogma of empiricism is the dualism of scheme and content, of organizing system and something waiting to be organized, which cannot be made intelligible and defensible. If we give it up, it is not clear that any distinctive empiricism remains.
     From: Donald Davidson (The Very Idea of a Conceptual Scheme [1974], p.189)
     A reaction: The first two dogmas were 'analyticity' and 'reductionism', as identified by Quine in 1953. Presumably Hume's Principles of Association (Idea 2189) would be an example of a scheme. A key issue is whether there is any 'pure' content.
Davidson says the world influences us causally; I say it influences us rationally [McDowell on Davidson]
     Full Idea: Davidson urges that we should hold that the world exerts a merely causal influence on our thinking, but I am trying to describe a way in which the world exerts a rational influence on our thinking.
     From: comment on Donald Davidson (Coherence Theory of Truth and Knowledge [1983]) by John McDowell - Mind and World II.5
     A reaction: McDowell seems to be fighting for the existence of 'pure' reason in a way that is hard to defend with a thoroughly materialist view of human brains. If the world is coherent, then maybe it is rational, and so has reasons to offer us?
12. Knowledge Sources / E. Direct Knowledge / 1. Common Sense
Apprehension is a complex intellect grasping the essence of a complex object [Holt,L]
     Full Idea: The paradigm case of apprehension is of a complex intellect confronted with a complex object, in which the intellect understands in a particular context what is 'essential' about the object.
     From: Lynn Holt (Apprehension: reason in absence of Rules [2002], 3 'Expertise')
     A reaction: My line is that this apprehension cashes out as an immediate ability to explain the object. This is an enhanced version of the rational understanding of things found in most larger animals. Holt says her account is Aristotelian.
13. Knowledge Criteria / A. Justification Problems / 1. Justification / a. Justification issues
It is common to doubt truth when discussing it, but totally accept it when discussing knowledge [Davidson]
     Full Idea: You are following Plato's lead if you worry about the concept of truth when it is the focus of your attention, but you pretend you understand it when trying to cope with knowledge (or belief, memory, perception etc.).
     From: Donald Davidson (The Folly of Trying to Define Truth [1999], p.20)
     A reaction: Nice to find someone pointing out this absurdity. He says Hume does the same with doubts about the external world, which he ignores when discussing other minds. Belief is holding true; only truths are actually remembered….
13. Knowledge Criteria / A. Justification Problems / 3. Internal or External / a. Pro-internalism
Reasons for beliefs are not the same as evidence [Davidson]
     Full Idea: We must find a reason for supposing most of our beliefs are true that is not a form of evidence.
     From: Donald Davidson (Coherence Theory of Truth and Knowledge [1983], p.158)
     A reaction: This simple observation strikes me as being a key truth in epistemology. It is the same confusion that creates Jackson's Knowledge Argument (Idea 7377) against physicalism (that experiencing red can be thought to be knowledge).
13. Knowledge Criteria / B. Internal Justification / 4. Foundationalism / f. Foundationalism critique
Sensations lack the content to be logical; they cause beliefs, but they cannot justify them [Davidson]
     Full Idea: The relation between a sensation and a belief cannot be logical, since sensations are not beliefs or propositional attitudes. The relation must be causal. Sensations cause some beliefs, but they do not show why the belief is justified.
     From: Donald Davidson (Coherence Theory of Truth and Knowledge [1983], p.157)
     A reaction: This is, I am beginning to think, the single most important idea in the whole of modern epistemology. Animals have beliefs caused in this way, and because they only have simple beliefs about immediate things, most of their beliefs are true.
13. Knowledge Criteria / B. Internal Justification / 5. Coherentism / a. Coherence as justification
Coherent justification says only beliefs can be reasons for holding other beliefs [Davidson]
     Full Idea: What distinguishes a coherence theory of justification is simply the claim that nothing can count as a reason for holding a belief except another belief.
     From: Donald Davidson (Coherence Theory of Truth and Knowledge [1983], p.156)
     A reaction: I think I agree fully with this. Red patches and headaches I count as evidence rather than as reasons. Since a red patch can be hallucinatory, and a headache can be dreamed, they can't possibly embody true propositions without critical evaluation.
13. Knowledge Criteria / D. Scepticism / 6. Scepticism Critique
Skepticism is false because our utterances agree, because they are caused by the same objects [Davidson]
     Full Idea: What stands in the way of global skepticism of the senses is the fact that we must take the objects of a belief to be the causes of that belief. And our utterances mean the same thing because belief in their truth is caused by the same objects.
     From: Donald Davidson (Coherence Theory of Truth and Knowledge [1983], p.161)
     A reaction: This is hardly a knock-down argument against scepticism, but it builds a nice picture. The second half extends the Private Language Argument (e.g. Idea 4158). But I still have non-existent conversations about non-existent things in my dreams.
13. Knowledge Criteria / E. Relativism / 2. Knowledge as Convention
Objectivity is intersubjectivity [Davidson]
     Full Idea: An entity is objective in so far as it is intersubjective.
     From: Donald Davidson (Three Varieties of Knowledge [1991]), quoted by Martin Kusch - Knowledge by Agreement Ch.10
     A reaction: This thought baffled me until I saw it in the context of socialised epistemology. Effectively objectivity is subsumed under justification, which in turn is seen in a social context, not private to individuals.
13. Knowledge Criteria / E. Relativism / 6. Relativism Critique
Different points of view make sense, but they must be plotted on a common background [Davidson]
     Full Idea: Different points of view make sense, but only if there is a common co-ordinate system on which to plot them.
     From: Donald Davidson (The Very Idea of a Conceptual Scheme [1974], p.184)
     A reaction: This seems right to me. I am very struck by the close similarities between people from wildly differing cultural backgrounds, as seen, for example, at the Olympic Games.
14. Science / D. Explanation / 1. Explanation / a. Explanation
Explanations typically relate statements, not events [Davidson]
     Full Idea: Explanations typically relate statements, not events.
     From: Donald Davidson (Causal Relations [1967], §4)
     A reaction: An oddly linguistic way of putting our attempts to understand the world. Presumably the statements are supposed to be about the events (or whatever), and they are supposed to be true, so we are trying to relate features of the world.
15. Nature of Minds / A. Nature of Mind / 1. Mind / a. Mind
There are no such things as minds, but people have mental properties [Davidson]
     Full Idea: There are no such things as minds, but people have mental properties.
     From: Donald Davidson (Davidson on himself [1994], p.231)
     A reaction: I think this is right. It fits with Searle's notion of consciousness as a property, like the liquidity of water. I don't panic if I think "I have no mind, but I have extraordinary properties".
15. Nature of Minds / A. Nature of Mind / 4. Other Minds / b. Scepticism of other minds
If we know other minds through behaviour, but not our own, we should assume they aren't like me [Davidson]
     Full Idea: If the mental states of others are known only through their behavioral and other outward manifestations, while this is not true of our own mental states, why should we think our own mental states are anything like those of others?
     From: Donald Davidson (Three Varieties of Knowledge [1991], p.207)
     A reaction: His point is that if you seriously doubt other minds, you should follow through on the implications. But that is to treat it as a theory about other minds, rather an a sceptical worry. Descartes didn't walk into walls while writing Meditation 1.
15. Nature of Minds / A. Nature of Mind / 4. Other Minds / c. Knowing other minds
Knowing other minds rests on knowing both one's own mind and the external world [Davidson, by Dummett]
     Full Idea: Davidson argues that knowledge of other minds presupposes knowledge of one's own mind, and that there is no knowledge of other minds without knowledge of the external world.
     From: report of Donald Davidson (Three Varieties of Knowledge [1991]) by Michael Dummett - Common Sense and Physics Ch.10
     A reaction: Davidson't argument is actually hard to swallow because it is so long and complex. Compressing the point makes it begin to sound like a variant of the argument from analogy.
15. Nature of Minds / C. Capacities of Minds / 5. Generalisation by mind
Predicates are a source of generality in sentences [Davidson]
     Full Idea: Predicates introduce generality into sentences.
     From: Donald Davidson (Truth and Predication [2005], 7)
     A reaction: Not sure about this. Most words introduce generality. 'From' is a very general word about direction. 'Dogs bark' is as generally about dogs as it is generally about barking.
16. Persons / A. Concept of a Person / 1. Existence of Persons
Metaphysics requires the idea of people (speakers) located in space and time [Davidson]
     Full Idea: An intelligible metaphysics will assign a central place to the idea of people (= speakers) with a location in public space and time.
     From: Donald Davidson (The Method of Truth in Metaphysics [1977], §III)
     A reaction: The 'location' is the interesting bit, requiring people to be bodies, not abstractions. A big, plausible claim, but hard to prove.
17. Mind and Body / B. Behaviourism / 4. Behaviourism Critique
There are no rules linking thought and behaviour, because endless other thoughts intervene [Davidson]
     Full Idea: We know too much about thought and behaviour to trust exact and universal statements linking them. Beliefs and desires issue in behaviour only as modified and mediated by further beliefs and desires, attitudes and attendings, without limit.
     From: Donald Davidson (Mental Events [1970], p.217)
     A reaction: Now seen as a key objection to behaviourism, and rightly so. However, I am not sure about "without limit", which implies an implausible absolute metaphysical freedom. Davidson goes too far in denying any nomological link between thought and brain.
17. Mind and Body / D. Property Dualism / 1. Reductionism critique
Reduction is impossible because mind is holistic and brain isn't [Davidson, by Maslin]
     Full Idea: Davidson rejects ontological reduction of mental to physical because propositional attitudes are holistic; there must be extensive coherence among someone's attitudes to treat them as a rational person, and this has no counterpart in physical theory.
     From: report of Donald Davidson (Mental Events [1970]) by Keith T. Maslin - Introduction to the Philosophy of Mind 7.5
     A reaction: I don't find this view persuasive. We treat the weather in simple terms, even though it is almost infinitely complex. Davidson has a Kantian overconfidence in our rationality. A coherence among the parts is needed to be a tree.
If the mind is an anomaly, this makes reduction of the mental to the physical impossible [Davidson]
     Full Idea: If there are no strict psychophysical laws, this rules out reductionism, either by definition of mental predicates in physical terms, or by way of bridging laws.
     From: Donald Davidson (Davidson on himself [1994], p.231)
     A reaction: But it is by no means clear that there are no psycho-physical laws. How could this be known a priori?
17. Mind and Body / D. Property Dualism / 2. Anomalous Monism
Anomalous monism says nothing at all about the relationship between mental and physical [Davidson, by Kim]
     Full Idea: Davidson's anomalous monism says no more about the relationship between the mental and the physical than the claim that all objects with a colour have a shape says about the relationship between colours and shapes.
     From: report of Donald Davidson (Mental Events [1970]) by Jaegwon Kim - Mind in a Physical World §1 p.005
     A reaction: Indeed, I find the enthusiasm for property dualism etc. quite baffling, given that we are merely told that mind is 'an anomaly'. I take it to be old fashioned dualism in trendy clothes.
Mind is outside science, because it is humanistic and partly normative [Davidson, by Lycan]
     Full Idea: For Davidson, mental types are individuated by considerations that are nonscientific, distinctly humanistic, and part normative, so will not coincide with any types that are designated in scientific terms.
     From: report of Donald Davidson (Mental Events [1970]) by William Lycan - Introduction - Ontology p.8
     A reaction: I just don't believe this, mainly because I don't accept that there is a category called 'nonscientific'. All we are saying is that a brain is a hugely complicated object, and we don't properly understand its operations, though we relate to it very well.
Anomalous monism says causes are events, so the mental and physical are identical, without identical properties [Davidson, by Crane]
     Full Idea: Davidson's anomalous monism says that events are causes, so we can identify mental and physical events without having to identify their properties.
     From: report of Donald Davidson (Mental Events [1970]) by Tim Crane - Elements of Mind 2.18
     A reaction: As Fodor insists, a thing like a mountain has properties at different levels of description. We can have 'property dualism' and full-blown reductive identity.
If rule-following and reason are 'anomalies', does that make reductionism impossible? [Davidson, by Kim]
     Full Idea: Davidson takes mental anomalism (that the mind exhibits normativity and rationality), and in particular his claim that there are no laws connecting mental and physical properties, to undermine mind-body reductionism.
     From: report of Donald Davidson (Mental Events [1970]) by Jaegwon Kim - Mind in a Physical World §4 p.092
     A reaction: A nice summary of the core idea of property dualism. Personally I expect the whole lot to be reducible, and to follow laws, but the sheer complexity of the brain permanently bars us from actually doing the reduction.
Davidson claims that mental must be physical, to make mental causation possible [Davidson, by Kim]
     Full Idea: Davidson's thesis is that if mental events of a particular kind cause physical events of a particular kind, and the two kinds are connected by a law, then they must both be physical kinds.
     From: report of Donald Davidson (Mental Events [1970]) by Jaegwon Kim - Philosophy of Mind p.137
     A reaction: Davidson would pretty obviously be right. The whole problem here is the idea of a 'law'. You can only have strict law for simple entities, like particles and natural kinds. The brain is a mess, like weather or explosions.
There are no strict psychophysical laws connecting mental and physical events [Davidson]
     Full Idea: There are no strict psychophysical laws (that is, laws connecting mental events under their mental descriptions with physical events under their physical descriptions).
     From: Donald Davidson (Davidson on himself [1994], p.231)
     A reaction: This is clearly open to question. It may be just that no human mind could ever grasp such laws, given their probable complexity.
Obviously all mental events are causally related to physical events [Davidson]
     Full Idea: All mental events are causally related to physical events. ..This seems obvious.
     From: Donald Davidson (Davidson on himself [1994], p.231)
     A reaction: All mental events are physically caused. Some bodily physical events result from mental events. Probably all mental events have some effect of other mental events (all of which are in some sense physical).
Mental entities do not add to the physical furniture of the world [Davidson]
     Full Idea: Mental entities do not add to the physical furniture of the world.
     From: Donald Davidson (Davidson on himself [1994], p.231)
     A reaction: This seems to me clearly true, however we propose to characterise mental events.
17. Mind and Body / D. Property Dualism / 3. Property Dualism
If mental causation is lawless, it is only possible if mental events have physical properties [Davidson, by Kim]
     Full Idea: Since no laws exist connecting mental and physical properties, purely physical laws must do the causal work, which means mental events enter into causal relations only because they possess physical properties that figure in laws.
     From: report of Donald Davidson (Mental Events [1970]) by Jaegwon Kim - Philosophy of Mind p.138
     A reaction: Surely no such laws exist 'yet'? I can see no plausible argument that psycho-physical laws are impossible. However, the conclusion of this remark seems right. Interaction requires some sort of equality.
The correct conclusion is ontological monism combined with conceptual dualism [Davidson]
     Full Idea: My basic premises lead to the conclusion of ontological monism coupled with conceptual dualism (like Spinoza, except that he denied mental causation).
     From: Donald Davidson (Davidson on himself [1994], p.231)
     A reaction: 'Conceptual dualism' implies no real difference, but 'property dualism' is better, suggesting different properties when viewed from different angles.
17. Mind and Body / D. Property Dualism / 5. Supervenience of mind
Supervenience of the mental means physical changes mental, and mental changes physical [Davidson]
     Full Idea: The supervenience [of mental characteristics on the physical] might be taken to mean that there cannot be two events alike in all physical respects but differing in some mental respect, or an object cannot differ mentally without altering physically.
     From: Donald Davidson (Mental Events [1970], I)
     A reaction: This is the first occasion on which Davidson introduced his notion of supervenience. Supervenience is often taken to be one-way. The first implies physical causing mental; his second implies that mental causes physical.
17. Mind and Body / E. Mind as Physical / 5. Causal Argument
Davidson sees identity as between events, not states, since they are related in causation [Davidson, by Lowe]
     Full Idea: Davidson's version of the identity theory is couched in terms of events rather than states, because he regards causation as a relation between events.
     From: report of Donald Davidson (Mental Events [1970]) by E.J. Lowe - Introduction to the Philosophy of Mind Ch.2 n12
     A reaction: I think it may be more to the point that the mind is a dynamic thing, and so it consists of events rather than states, and hence we want to know what those events are made up from. I think my chair is causing me to rest above the floor…
Cause unites our picture of the universe; without it, mental and physical will separate [Davidson]
     Full Idea: The concept of cause is what holds together our picture of the universe, a picture that would otherwise disintegrate into a diptych of the mental and the physical.
     From: Donald Davidson (Intro to 'Essays on Actions and Events' [1980], p.xi)
     A reaction: Davidson seems to be the one who put mental causation at the centre of philosophy. By then denying that there are any 'psycho-physical' laws, he seems to me to have re-opened the metaphysical gap he says he was trying to close.
17. Mind and Body / E. Mind as Physical / 7. Anti-Physicalism / b. Multiple realisability
Multiple realisability was worse news for physicalism than anomalous monism was [Davidson, by Kim]
     Full Idea: Davidson's argument about psychophysical anomalism has not been embraced by everyone; multiple realisability of mental properties has had a much greater impact in undermining reductionism (and hence type physicalism).
     From: report of Donald Davidson (Mental Events [1970]) by Jaegwon Kim - Philosophy of Mind p.218
     A reaction: My view is that functional states are multiply realisable, but phenomenal states aren't. Fear functions in frogs much as it does in us, but being a frightened frog is nothing like being a frightened human. Their brains are different!
18. Thought / A. Modes of Thought / 1. Thought
Thought depends on speech [Davidson]
     Full Idea: The thesis I want to refine and then argue for is that thought depends on speech.
     From: Donald Davidson (Thought and Talk [1975], p.8)
     A reaction: This has the instant and rather implausible implication that animals don't think. He is not, of course, saying that all thought is speech, which would leave out thinking in images. You can't do much proper thought without concepts and propositions.
18. Thought / A. Modes of Thought / 5. Rationality / a. Rationality
Absence of all rationality would be absence of thought [Davidson]
     Full Idea: To imagine a totally irrational animal is to imagine an animal without thought.
     From: Donald Davidson (Davidson on himself [1994], p.232)
     A reaction: This wouldn't be so clear without the theory of evolution, which suggests that only the finders of truth last long enough to breed.
18. Thought / A. Modes of Thought / 8. Human Thought
A creature doesn't think unless it interprets another's speech [Davidson]
     Full Idea: A creature cannot have a thought unless it is an interpreter of the speech of another.
     From: Donald Davidson (Thought and Talk [1975], p.9)
     A reaction: His use of the word 'creature' shows that he is perfectly aware of the issue of whether animals think, and he is, presumably, denying it. At first glance this sounds silly, but maybe animals don't really 'think', in our sense of the word.
18. Thought / B. Mechanics of Thought / 1. Psychology
In no important way can psychology be reduced to the physical sciences [Davidson]
     Full Idea: There is no important sense in which psychology can be reduced to the physical sciences.
     From: Donald Davidson (The Material Mind [1973], p.259)
     A reaction: In no 'important' way can the beauty of the Lake District be reduced to geology - but it is geology. 'Important' to whom? To a metaphysician, I would say psychology does reduce to physics, and that is important, but it is not important to a psychologist.
18. Thought / C. Content / 6. Broad Content
External identification doesn't mean external location, as with sunburn [Davidson, by Rowlands]
     Full Idea: Davidson observes that the inference from a thought being identified by a relation to something outside the head does not entail that the thought is not wholly in the head, just as sunburn is identified by external factors, but is still in the skin.
     From: report of Donald Davidson (Knowing One's Own Mind [1987]) by Mark Rowlands - Externalism Ch.8
     A reaction: Rowlands (an externalist) agrees, and this strikes me as correct, and it needs to be one of the fixed points in any assessment of externalism.
Our meanings are partly fixed by events of which we may be ignorant [Davidson]
     Full Idea: What we mean by what we say is partly fixed by events of which we may be ignorant.
     From: Donald Davidson (Davidson on himself [1994], p.235)
     A reaction: There is 'strict and literal meaning', which is fixed by the words, even if I don't know what I am saying. But 'speaker's meaning' is surely a pure matter of a state of mind?
It is widely supposed that externalism cannot be reconciled with first-person authority [Davidson]
     Full Idea: It has been widely supposed that externalism, which holds that the contents of a person's propositional attitudes are partly determined by factors of which the person may be ignorant, cannot be reconciled with first-person authority.
     From: Donald Davidson (Epistemology Externalized [1990], p.197)
     A reaction: It is certainly a bit puzzling if you go around saying 'Actually, people don't know their own thoughts'. Davidson aims to defend first-person authority. The full story is developed in Tyler Burge's views on 'anti-individualism'.
It is hard to interpret a speaker's actions if we take a broad view of the content [Davidson]
     Full Idea: It will explain a speaker's actions far better if we interpret him as he intended to be interpreted, than if we suppose he means and thinks what someone else might mean and think who used the same words 'correctly'.
     From: Donald Davidson (Epistemology Externalized [1990], p.199)
     A reaction: This comes down to the fact that our actions have to be motivated by internal meanings. If I defer to experts on the essence of gold, I still buy gold according to how I myself understand it. So meaning has two components?
Meanings aren't in the head, but that is because they are abstract [Stalnaker]
     Full Idea: Meanings ain't in the head. Putnam's famous slogan actually fits Frege's anti-psychologism better than it fits Purnam's and Burge's anti-individualism. The point is that intensions of any kind are abstract objects.
     From: Robert C. Stalnaker (Conceptual truth and metaphysical necessity [2003], 2)
     A reaction: If intensions are abstract, that leaves (for me) the question of what they are abstracted from. I take it that there are specific brain events that are being abstractly characterised. What do we call those?
How can we know what we are thinking, if content depends on something we don't know? [Stalnaker]
     Full Idea: How can we know what we ourselves are thinking if the very existence of the content of our thought may depend on facts of which we are ignorant?
     From: Robert C. Stalnaker (Mere Possibilities [2012], 5)
     A reaction: This has always been my main doubt about externalism. I may defer to experts about what I intend by an 'elm' (Putnam's example), but what I mean by elm is thereby a fuzzy tall tree with indeterminate leaves. I don't know the meaning of 'elm'!
18. Thought / D. Concepts / 5. Concepts and Language / a. Concepts and language
Concepts are only possible in a language community [Davidson]
     Full Idea: A private attitude is not intelligible except as an adjustment to the public norms provided by language. It follows that a creature must be a member of speech community if it is to have the concept of belief.
     From: Donald Davidson (Thought and Talk [1975], p.170)
     A reaction: This obviously draws on Wittgenstein's private language argument, and strikes me as blatantly wrong, because I take higher animals to have concepts without language. Pure vision gives rise to concepts. I don't even think they are necessarily conscious.
19. Language / A. Nature of Meaning / 1. Meaning
If you don't know what you say you can't mean it; what people say usually fits what they mean [Stalnaker]
     Full Idea: If you don't know what you are saying then you don't mean what you say, and also speakers generally mean what they say (in that what they say coincides with what they mean).
     From: Robert C. Stalnaker (Reference and Necessity [1997], 4)
     A reaction: Both these thoughts seem completely acceptable and correct, but rely on something called 'meaning' that is distinct from saying. I would express this in terms of propositions, which I take to be mental events.
A minimum requirement for a theory of meaning is that it include an account of truth [Davidson]
     Full Idea: Whatever else it embraces, a theory of meaning must include an account of truth - a statement of the conditions under which an arbitrary sentence of the language is true.
     From: Donald Davidson (Reality without Reference [1977], p.132)
     A reaction: It is a moot point whether we can define meaning if we assume truth, or if we can define truth by assuming meaning. Tarski seems to presuppose meaning when he defines truth (Idea 2345). I like Davidson's taking of truth as basic.
19. Language / A. Nature of Meaning / 2. Meaning as Mental
If we reject corresponding 'facts', we should also give up the linked idea of 'representations' [Davidson]
     Full Idea: If we give up facts that make entities true, we ought to give up representations at the same time, for the legitimacy of each depends on the legitimacy of the other.
     From: Donald Davidson (Truth and Predication [2005], 2)
     A reaction: Not sure about this, because I'm not sure I know what he means by 'representations'. Surely every sentence is 'about' something? Is that just the references within the sentence, but not the sentence as a whole?
19. Language / A. Nature of Meaning / 4. Meaning as Truth-Conditions
You only understand an order if you know what it is to obey it [Davidson]
     Full Idea: We understand an imperative if and only if we know under what conditions what it orders or commands is obeyed.
     From: Donald Davidson (Truth and Predication [2005], 6)
     A reaction: How could this be wrong? 'Do you understand the order?' 'Yes sir!' 'Well do it then!' 'Do what sir?'
Davidson rejected ordinary meaning, and just used truth and reference instead [Davidson, by Soames]
     Full Idea: Davidson held that knowledge of truth and reference could give us a notion of meaning. He embraced Quine's rejection of analyticity, synonymy and ordinary meaning, and substituted truth and reference, when there was something genuine to capture.
     From: report of Donald Davidson (Semantics for Natural Languages [1970]) by Scott Soames - Philosophy of Language 2.3
     A reaction: I always get a warm glow when anyone suggests that the concept of meaning involves the concept of truth. I largely reject Quine. Davidson made a helpful suggestion!
Davidson aimed to show that language is structured by first-order logic [Davidson, by Smart]
     Full Idea: Davidson's program was to show the underlying structure of natural languages as that of first-order logic.
     From: report of Donald Davidson (Semantics for Natural Languages [1970], 2) by J.J.C. Smart - The Tenseless Theory of Time 2
     A reaction: First order logic just reasons about a domain of objects with predicates attached to them. Language appears to refer to properties and relations as well as objects.
Sentences held true determine the meanings of the words they contain [Davidson]
     Full Idea: Sentences held true (the linguistic representatives of beliefs) determine the meanings of the words they contain.
     From: Donald Davidson (The Method of Truth in Metaphysics [1977], §II)
     A reaction: Maybe. Historically, truth and belief presumably precede words and sentences. But words separate off from beliefs very easily. I'm not convinced. Words initiate language, not beliefs?
A theory of truth tells us how communication by language is possible [Davidson]
     Full Idea: A theory of truth lets us answer the underlying question how communication by language is possible.
     From: Donald Davidson (Reality without Reference [1977], p.137)
     A reaction: If, instead, you explain communication by understood intentions (á la Grice), you have to say more about what sort of intentions are meant. If you use reference, you still have more to say about the meaning of sentences. Davidson looks good.
Knowing the potential truth conditions of a sentence is necessary and sufficient for understanding [Davidson]
     Full Idea: It is clear that someone who knows under what conditions a sentence would be true understands that sentence, …and if someone does not know under what conditions it would be true then they do not understand it.
     From: Donald Davidson (Truth Rehabilitated [1997], p.13)
     A reaction: I've always subscribed to this view. Langauge is meaningless if you can't relate it to reality, and I don't think there could be a language without an intuitive notion of truth.
Utterances have the truth conditions intended by the speaker [Davidson]
     Full Idea: An utterance has certain truth conditions only if the speaker intends it to be interpreted as having those truth conditions.
     From: Donald Davidson (Truth and Predication [2005], 3)
     A reaction: This seems to be a concession to the rather sensible things that Grice said about meaning. What about malapropisms? Surely there the speaker does not understand the truth conditions of her own utterance? Truth conditions are in the head?
19. Language / A. Nature of Meaning / 6. Meaning as Use
Meaning involves use, but a sentence has many uses, while meaning stays fixed [Davidson]
     Full Idea: Meaning depends on use, but it is not easy to say how, for uses to which we may put the utterance of a sentence are endless while its meaning remains fixed.
     From: Donald Davidson (Truth and Predication [2005], 6)
     A reaction: Quite so. The password is 'Swordfish' (or 'Sweet marjoram', if you prefer).
An understood sentence can be used for almost anything; it isn't language if it has only one use [Davidson]
     Full Idea: Once a sentence is understood, an utterance of it may be used to serve almost any extra-linguistic purpose; an instrument that could be put to only one use would lack autonomy of meaning, which means it should not be counted as language.
     From: Donald Davidson (Thought and Talk [1975], p.17)
     A reaction: I find this point very appealing, in opposition to the Wittgenstein view of meaning as use. Passwords seem to me a striking case of the separation of meaning and use. I like the phrase 'autonomy of meaning'. Random sticks can form a word.
It could be that the use of a sentence is explained by its truth conditions [Davidson]
     Full Idea: It may be that sentences are used as they are because of their truth conditions, and they have the truth conditions they do because of how they are used.
     From: Donald Davidson (Truth Rehabilitated [1997], p.13)
     A reaction: I've always taken the attempt to explain meaning by use as absurd. It is similar to trying to explain mind in terms of function. In each case, what is the intrinsic nature of the thing, which makes that use or that function possible?
19. Language / A. Nature of Meaning / 7. Meaning Holism / a. Sentence meaning
We recognise sentences at once as linguistic units; we then figure out their parts [Davidson]
     Full Idea: Our interest in the parts of sentences is derivative; we recognise at once that sentences are effective linguistic units, while we must figure out or decide what constitutes the meaningful words and particles.
     From: Donald Davidson (Truth and Predication [2005], Intro)
     A reaction: It depends on whether linguistic priority goes to complete thoughts that require expression, or to naming and ostensive definition to relate to elements of the environment. I find it hard to have a strong view on this one. Just So stories?
19. Language / A. Nature of Meaning / 7. Meaning Holism / b. Language holism
The pattern of sentences held true gives sentences their meaning [Davidson]
     Full Idea: Although most utterances are not concerned with truth, it is the pattern of sentences held true that gives sentences their meaning.
     From: Donald Davidson (Thought and Talk [1975], p.14)
     A reaction: Davidson's distinctive version of meaning holism, as opposed to Quine's rather behaviouristic version. I agree that we relate to people through the pattern of sentences they hold true, but I am unconvinced that this 'gives sentences their meaning'.
19. Language / B. Reference / 1. Reference theories
Is reference the key place where language and the world meet? [Davidson]
     Full Idea: The essential question is whether reference is the, or at least one, place where there is direct contact between linguistic theory and events, actions, or objects described in nonlinguistic terms.
     From: Donald Davidson (Reality without Reference [1977], p.134)
     A reaction: How do you 'describe objects in nonlinguistic terms'? The causal theory of reference (e.g. Idea 4957) is designed to plug language straight into the world via reference. It simplifies things nicely, but I don't quite believe it.
With a holistic approach, we can give up reference in empirical theories of language [Davidson]
     Full Idea: I defend a version of the holistic approach, and urge that we must give up the concept of reference as basic to an empirical theory of language.
     From: Donald Davidson (Reality without Reference [1977], p.136)
     A reaction: He proposes to connect language to the world via the concept of truth, rather than of reference. It is a brilliant idea, and is the key issue in philosophy of language. I go back to animals, which seem to care about situations rather than things.
19. Language / B. Reference / 3. Direct Reference / b. Causal reference
In the use of a name, many individuals are causally involved, but they aren't all the referent [Stalnaker]
     Full Idea: The causal theory of reference is criticised for vagueness. Causal connections are ubiquitous, and there are obviously many individuals that are causally implicated in the speaker's use of a name, but they aren't all plausible candidates for the referent.
     From: Robert C. Stalnaker (Reference and Necessity [1997], 4)
     A reaction: This seems to be a very good objection. Among all the causal links back to some baptised object, we have to pick out the referential link, which needs a criterion.
One view says the causal story is built into the description that is the name's content [Stalnaker]
     Full Idea: In 'causal descriptivism' the causal story is built into the description that is the content of the name (and also incorporates a rigidifying operator to ensure that the descriptions that names abbreviate have wide scope).
     From: Robert C. Stalnaker (Conceptual truth and metaphysical necessity [2003], 5)
     A reaction: Not very controversial, I would say, since virtually every fact about the world has a 'causal story' built into it. Must we insist on rigidity in order to have wide scope?
19. Language / B. Reference / 4. Descriptive Reference / b. Reference by description
To explain the reference of a name, you must explain its sentence-role, so reference can't be defined nonlinguistically [Davidson]
     Full Idea: It is inconceivable that one should be able to explain the relationship between 'Kilimanjiro' and Kilimanjiro without first explaining the role of the word in sentences; hence there is no chance of explaining reference directly in nonlinguistic terms.
     From: Donald Davidson (Reality without Reference [1977], p.135)
     A reaction: I point at the mountain, and a local says 'Kilimanjiro'? There is a 'gavagai'-type problem with that. The prior question might be 'what is it about this word that enables it to have a role in sentences?' Unlike whimpering or belching.
19. Language / C. Assigning Meanings / 2. Semantics
'Descriptive' semantics gives a system for a language; 'foundational' semantics give underlying facts [Stalnaker]
     Full Idea: 'Descriptive' semantics gives a semantics for the language without saying how practice explains why the semantics is right; …'foundational' semantics concerns the facts that give expressions their semantic values.
     From: Robert C. Stalnaker (Reference and Necessity [1997], §1)
     A reaction: [compressed] Sounds parallel to the syntax/semantics distinction, or proof-theoretical and semantic validity. Or the sense/reference distinction! Or object language/metalanguage. Shall I go on?
We still lack an agreed semantics for quantifiers in natural language [Stalnaker]
     Full Idea: We still do not know how to give a direct semantics for the quantifiers of a natural language; that is something that we still do not know how to do (or at least how it is done remains controversial).
     From: Robert C. Stalnaker (Mere Possibilities [2012], 4)
     A reaction: I am struck by how rapidly the domain of quantification changes, even in mid-sentence, in the course of an ordinary conversation. This is decided almost entirely by context, not by pure ('direct'?) semantics.
19. Language / C. Assigning Meanings / 3. Predicates
Modern predicates have 'places', and are sentences with singular terms deleted from the places [Davidson]
     Full Idea: The notion of 'places' in a predicate is the key to the modern concept of a predicate. Any expression obtained from a sentence by deleting one or more singular terms from the sentence counts as a predicate.
     From: Donald Davidson (Truth and Predication [2005], 4)
The concept of truth can explain predication [Davidson]
     Full Idea: My strategy is to show how our grasp of the concept of truth can explain predication.
     From: Donald Davidson (Truth and Predication [2005], 7)
     A reaction: His account of the concept of truth centres on Tarski's theory, but he clearly thinks more is needed than the bare bones offered by Tarski. The point, I think, is that predication is what makes a sentence 'truth-apt'.
19. Language / C. Assigning Meanings / 4. Compositionality
Compositionality explains how long sentences work, and truth conditions are the main compositional feature [Davidson, by Lycan]
     Full Idea: Davidson's main argument in favour of his truth conditions theory of meaning is that compositionality is needed to account for our understanding of long, novel sentences, and a sentence's truth condition is its most obviously compositional feature.
     From: report of Donald Davidson (Truth and Meaning [1967]) by William Lycan - Philosophy of Language Ch.9
     A reaction: This seems to me exactly right. As we hear a new long sentence unfold, we piece together the meaning. At the end we may spot that the meaning is silly, or an unverifiable speculation, or not what the speaker intended - but it is too late! It means.
If you assign semantics to sentence parts, the sentence fails to compose a whole [Davidson]
     Full Idea: The puzzle is that once plausible assignments of semantic roles have been made to parts of sentences, the parts do not seem to compose a united whole.
     From: Donald Davidson (Truth and Predication [2005], Intro)
     A reaction: It's not clear to me that a sentence does compose a 'whole', given that you can often add or remove bits from sentences, sometimes without changing the meaning. We often, in speech, assemble sentences before we have thought of their full meaning.
19. Language / C. Assigning Meanings / 5. Fregean Semantics
Davidson thinks Frege lacks an account of how words create sentence-meaning [Davidson, by Miller,A]
     Full Idea: Davidson thinks that Frege's model for a theory of semantic value (and thereby for a systematic theory of sense) is unsatisfactory, because it provides no useful or explanatory account of how sentence-meaning can be a function of word-meaning.
     From: report of Donald Davidson (Truth and Meaning [1967]) by Alexander Miller - Philosophy of Language 8.1
     A reaction: Put like that, it is not clear to me how you could even start to explain how word-meaning contributes to sentence meaning. Try speaking any sentence slowly, and observe how the sentence meaning builds up. Truth is, of course, relevant.
A theory of meaning comes down to translating sentences into Fregean symbolic logic [Davidson, by Macey]
     Full Idea: For a theory of meaning for a fragment of natural language, what Davidson requires, in effect, is that the sentences be translatable into the language of Frege's symbolic logic.
     From: report of Donald Davidson (In Defence of Convention T [1973]) by David Macey - Penguin Dictionary of Critical Theory
     A reaction: This assumes the adequacy of Fregean logic, which seems unlikely. Is this the culmination of Leibniz's dream of a fully logical language - so that anything that won't fit into our logical form is ruled (logical positivist style) as meaningless?
19. Language / C. Assigning Meanings / 6. Truth-Conditions Semantics
Top-down semantic analysis must begin with truth, as it is obvious, and explains linguistic usage [Davidson]
     Full Idea: Truth is the essential semantic concept with which to begin a top-down analysis of sentences, since truth, or lack of it, is the most obvious semantic property of sentences, and provides the clearest explanation of judging and conveying information.
     From: Donald Davidson (Truth and Predication [2005], Intro)
     A reaction: [a bit compressed] Presumably this goes with giving sentences semantic priority. The alternative approach is compositional, and is likely to give reference of terms priority over truth of the sentence. But accurate reference is a sort of truth.
To understand an utterance, you must understand what the world would be like if it is true [Stalnaker]
     Full Idea: To understand what is said in an utterance of 'The first dog born at sea was a basset hound', one needs to know what the world would have been like in order for what was said in that utterance to be true.
     From: Robert C. Stalnaker (Reference and Necessity [1997], 3)
     A reaction: Put like that, the idea is undeniable. Understanding involves truth conditions. Does mean involve the understanding of the meaning. What do you understand when you understand a sentence? Just facts about dogs? Or something in the sentence?
19. Language / C. Assigning Meanings / 8. Possible Worlds Semantics
Extensional semantics has individuals and sets; modal semantics has intensions, functions of world to extension [Stalnaker]
     Full Idea: Semantic values in extensional semantics are extensions, like individuals for terms, and sets for predicates. In modal semantics we have intensions, functions from worlds to appropriate extensions.
     From: Robert C. Stalnaker (Counterparts and Identity [1987], 2)
     A reaction: It seems obvious that the meaning of a word like 'giraffe' must include possible giraffes, as well as actual and deceased giraffes.
Possible world semantics may not reduce modality, but it can explain it [Stalnaker]
     Full Idea: Most theorists agree that possible worlds semantics cannot provide an analysis of modal concepts which is an eliminative reduction, but it can still provide an explanation of the meanings of modal expressions.
     From: Robert C. Stalnaker (Mere Possibilities [2012], 2.2)
     A reaction: Stalnaker cites Kit Fine for the view that there is no reduction of modality, which Fine takes to be primitive. Stalnaker defends the semantics, while denying the reduction which Lewis thought possible.
19. Language / C. Assigning Meanings / 9. Indexical Semantics
You can state truth-conditions for "I am sick now" by relativising it to a speaker at a time [Davidson, by Lycan]
     Full Idea: Davidson's response to the problem of how you would state truth conditions for "I am sick now" ...is to relativize its truth to a particular speaker and a time.
     From: report of Donald Davidson (Truth and Meaning [1967]) by William Lycan - Philosophy of Language Ch.9
     A reaction: Lycan is not happy with this, but it seems a reasonable way to treat the truth of any statement containing indexicals. Never mind the 'truth conditions theory of meaning' - just ask whether "I am sick now" is true.
19. Language / C. Assigning Meanings / 10. Two-Dimensional Semantics
Two-D says that a posteriori is primary and contingent, and the necessity is the secondary intension [Stalnaker]
     Full Idea: Two-dimensionalism says the necessity of a statement is constituted by the fact that the secondary intensions is a necessary proposition, and their a posteriori character is constituted by the fact that the associated primary intension is contingent.
     From: Robert C. Stalnaker (Conceptual truth and metaphysical necessity [2003], 2)
     A reaction: This view is found in Sidelle 1989, and then formalised by Jackson and Chalmers. I like metaphysical necessity, but I have some sympathy with the approach. The question must always be 'where does this necessity derive from'?
In one view, the secondary intension is metasemantic, about how the thinker relates to the content [Stalnaker]
     Full Idea: On the metasemantic interpretation of the two-dimensional framework, the second dimension is used to represent the metasemantic facts about the relation between a thinker or speaker and the contents of her thoughts or utterances.
     From: Robert C. Stalnaker (Conceptual truth and metaphysical necessity [2003], 4)
     A reaction: I'm struggling to think what facts there might be about the relation between myself and the contents of my thoughts. I'm more or less constituted by my thoughts.
19. Language / D. Propositions / 1. Propositions
I take propositions to be truth conditions [Stalnaker]
     Full Idea: I will defend the view that propositions are truth conditions.
     From: Robert C. Stalnaker (Mere Possibilities [2012], 1.2)
     A reaction: This sounds close to the Russellian view, which I take to equate propositions (roughly) with facts or states of affairs. But are 'truth conditions' in the world or in the head?
'Humanity belongs to Socrates' is about humanity, so it's a different proposition from 'Socrates is human' [Davidson]
     Full Idea: The sentence 'Humanity belongs to Socrates' is about the concept of humanity, unlike the "equivalent" 'Socrates is human', so they express different propositions.
     From: Donald Davidson (Truth and Predication [2005], 5)
     A reaction: [compressed] I like this a lot, because it shows why we should focus on propositions rather than on sentences, or even utterances. And asking what the sentence is 'about' focuses us on the underlying proposition or thought.
A theory of propositions at least needs primitive properties of consistency and of truth [Stalnaker]
     Full Idea: A minimal theory of propositions can make do with just two primitive properties: a property of consistency applied to sets of propositions, and a property of truth applied to propositions.
     From: Robert C. Stalnaker (Mere Possibilities [2012], 2)
     A reaction: I would have thought a minimal theory would need some account of what a proposition is supposed to be (since there seems to be very little agreement about that). Stalnaker goes on to sketch a theory.
19. Language / D. Propositions / 3. Concrete Propositions
A 'Russellian proposition' is an ordered sequence of individual, properties and relations [Stalnaker]
     Full Idea: A 'Russellian proposition' is an ordered sequence containing the individual, along with properties and relations.
     From: Robert C. Stalnaker (Merely Possible Propositions [2010], p.22)
     A reaction: Since Russell took properties and relations to be features of reality, this made the whole proposition a feature of reality. This is utterly different from what I understand by the word 'proposition', which is a feature of thought, not of the world.
Propositions presumably don't exist if the things they refer to don't exist [Stalnaker]
     Full Idea: It seems plausible that singular propositions are object-dependent in the sense that the proposition would not exist if the individual did not. It is also plausible that some objects exist contingently, and there are singular propositions about them.
     From: Robert C. Stalnaker (Mere Possibilities [2012], 2)
     A reaction: This replies to the view that possible worlds are maximal sets of propositions, and so must exist for the worlds to exist; e.g. Lowe 1999:248. That is yet another commonplace of contemporary philosophy which I find utterly bewildering.
19. Language / D. Propositions / 6. Propositions Critique
Propositions explain nothing without an explanation of how sentences manage to name them [Davidson]
     Full Idea: The idea of a proposition is unhelpful, until it is explained how exactly the words in the contained sentence manage to name or describe a proposition (which even Frege failed to achieve).
     From: Donald Davidson (Davidson on himself [1994], p.232)
     A reaction: It seems obvious to me that there are brain events best labelled as propositions, even if their fit with language is puzzling.
19. Language / F. Communication / 2. Assertion
An assertion aims to add to the content of a context [Stalnaker, by Magidor]
     Full Idea: Stalnaker starts with the general thesis that the role of a successful assertion of s is to update the context by adding to it the content of s.
     From: report of Robert C. Stalnaker (Assertion [1978]) by Ofra Magidor - Category Mistakes 5.3.2
     A reaction: This is to be compared with criteria of meaningfulness, such as verificationism, and with Grice's rules of conversational implicature. Presumably if you assert what the context presupposes, you fail to assert, without being meaningless.
19. Language / F. Communication / 4. Private Language
Thought is only fully developed if we communicate with others [Davidson]
     Full Idea: We would have no fully-fledge thoughts if we were not in communication with others.
     From: Donald Davidson (Davidson on himself [1994], p.233)
     A reaction: This seems a plausible empirical observation, though I would doubt any a priori proof of it. If animals could speak, they would become intellectuals?
Content of thought is established through communication, so knowledge needs other minds [Davidson]
     Full Idea: Until a baseline has been established by communication with someone else, there is no point is saying one's own thoughts have a propositional content. Hence knowledge of another mind is essential all thought and all knowledge.
     From: Donald Davidson (Three Varieties of Knowledge [1991], p.213)
     A reaction: This really is building a skyscraper on the slightly shaky claims of the Private Language Argument (e.g. Idea 4158). Animals are so important in discussions of this kind. Is an albatross more or less devoid of thought and belief?
19. Language / F. Communication / 5. Pragmatics / b. Implicature
An assertion is an attempt to rule out certain possibilities, narrowing things down for good planning [Stalnaker, by Schroeter]
     Full Idea: Stalnaker's guiding idea is that in making an assertion the speaker is trying to get the audience to rule out certain possibilities. ....If all goes well, further planning will proceed on the basis of a smaller and more accurate range of possibilities.
     From: report of Robert C. Stalnaker (Assertion [1978]) by Laura Schroeter - Two-Dimensional Semantics
     A reaction: This sounds intuitively rather plausible, and is a nice original thought. This is what we pay clever chaps like Stalnaker to come up with. It seems to imply some notion of verisimilitude (qv. under 'truth'), depending on how much narrowing happens.
19. Language / F. Communication / 6. Interpreting Language / b. Indeterminate translation
Should we assume translation to define truth, or the other way around? [Blackburn on Davidson]
     Full Idea: The concern of some philosophers has been expressed by saying that whereas Tarski took translation for granted, and sought to understand truth, Davidson takes truth for granted, and seeks to understand translation.
     From: comment on Donald Davidson (Truth and Meaning [1967]) by Simon Blackburn - Oxford Dictionary of Philosophy p.82
     A reaction: We can just say that the two concepts are interdependent, but my personal intuitions side with Davidson. If you are going to take something as fundamental and axiomatic, truth looks a better bet than translation.
Criteria of translation give us the identity of conceptual schemes [Davidson]
     Full Idea: Studying the criteria of translation is a way of focusing on criteria of identity for conceptual schemes.
     From: Donald Davidson (The Very Idea of a Conceptual Scheme [1974], p.184)
     A reaction: This is why it was an inspired idea of Quine's to make translation a central topic in philosophy. We must be cautious, though, about saying that the language is the conceptual scheme, as that leaves animals with no scheme at all.
19. Language / F. Communication / 6. Interpreting Language / c. Principle of charity
Davidson's Cogito: 'I think, therefore I am generally right' [Davidson, by Button]
     Full Idea: Davidson's Cogito has the form 'I think, therefore I am generally right'.
     From: report of Donald Davidson (Coherence Theory of Truth and Knowledge [1983], 16.6) by Tim Button - The Limits of Reason
     A reaction: On the whole I would subscribe to this Cogito (as Button calls it), from an evolutionary perspective. There would just be no point in thought if it wasn't generally right in everyday activity.
The principle of charity attributes largely consistent logic and largely true beliefs to speakers [Davidson]
     Full Idea: Concerning charity, the Principle of Coherence seeks logical consistency in the thought of the speaker, and the Principle of Correspondence seeks a similar response to features of the world to that of an interpreter. The speaker has logic and true belief.
     From: Donald Davidson (Three Varieties of Knowledge [1991], p.211)
     A reaction: Davidson adds a Kantian commitment to pure and universal reason to the very sceptical framework created by Quine. I agree with Davidson, but it seems more like faith than like an argument or an empirical observation.
There is simply no alternative to the 'principle of charity' in interpreting what others do [Davidson]
     Full Idea: The 'principle of charity' is a misleading term, since there is no alternative if we want to make sense of the attitudes and actions of the agents around us.
     From: Donald Davidson (Davidson on himself [1994], p.233)
     A reaction: I suppose so, but only with a background of evolutionary theory. I would necessarily assume charity if a robot spoke to me.
The principle of charity says an interpreter must assume the logical constants [Davidson]
     Full Idea: The principle of charity says that it is unavoidable that the pattern of sentences to which a speaker assents reflects the semantics of the logical constants.
     From: Donald Davidson (Truth and Predication [2005], 3)
     A reaction: That is not all the principle says, of course. Davidson seems to assume classical logic here, with a bivalent semantics. I wonder if all speakers use 'false' in the normal way, as well as 'true'? Do all languages even contain 'true'?
19. Language / F. Communication / 6. Interpreting Language / d. Metaphor
We indicate use of a metaphor by its obvious falseness, or trivial truth [Davidson]
     Full Idea: The sentences that contain metaphors are typically obviously false or trivially true, because these are typically indications that something is intended as a metaphor.
     From: Donald Davidson (Truth and Predication [2005], 6)
     A reaction: A nice point which sounds correct. Metaphors are famous being false, but the 'obvious' falseness signals the metaphor. If a metaphor is only obscurely false, that makes it difficult to read.
Understanding a metaphor is a creative act, with no rules [Davidson]
     Full Idea: Understanding a metaphor is as much a creative endeavour as making a metaphor, and as little guided by rules.
     From: Donald Davidson (What Metaphors Mean [1978], p.29)
     A reaction: This is good news for literature studies courses. Davidson's point is that the metaphor itself only gives you a literal meaning, so it doesn't tell you how to interpret it. It seems an attractive proposal.
Metaphors just mean what their words literally mean [Davidson]
     Full Idea: Metaphors mean what the words, in their most literal interpretation, mean, and nothing more.
     From: Donald Davidson (What Metaphors Mean [1978], p.30)
     A reaction: This pronouncement must be the result of Davidson anguishing over the truth conditions for metaphors, which are usually either taken to have a 'metaphorical meaning', or to be abbreviated similes. He solved his problem at a stroke! Plausible.
We accept a metaphor when we see the sentence is false [Davidson]
     Full Idea: It is only when a sentence is taken to be false that we accept it as a metaphor.
     From: Donald Davidson (What Metaphors Mean [1978], p.40)
     A reaction: This strikes me as a very nice and true generalisation, even though Davidson mentions "no man is an island" as a counterexample. We thirst for meaning, and switch to a second meaning when the first one looks peculiar.
20. Action / A. Definition of Action / 2. Duration of an Action
If one action leads directly to another, they are all one action [Davidson, by Wilson/Schpall]
     Full Idea: Davidson (1980 ess 1) agreed with Anscombe that if a person Fs by G-ing, then her act F = her act G. For example, if someone accidentally alerts a burglar, by deliberately turning on a light, by flipping a switch, these are all the same action.
     From: report of Donald Davidson (Action, Reasons and Causes [1963]) by Wilson,G/Schpall,S - Action 1.2
     A reaction: I would have thought there was obviously a strong conventional element in individuating actions, depending on interest. An electrician is only interest in whether the light worked. The police are only interested in the disturbance of the burglar.
20. Action / B. Preliminaries of Action / 1. Intention to Act / a. Nature of intentions
We explain an intention by giving an account of acting with an intention [Davidson, by Stout,R]
     Full Idea: The early Davidson championed the approach that we explain the idea of having an intention by providing an account of what it is to act with an intention.
     From: report of Donald Davidson (Action, Reasons and Causes [1963]) by Rowland Stout - Action 7 'Conclusion'
     A reaction: This eliminates the distinction between a prior intention, and the intention that maintains a process such as speech. It sounds almost behaviourist.
An intending is a judgement that the action is desirable [Davidson]
     Full Idea: We can identify an intentional action ...with an all-out conditional judgement that the action is desirable. ...In the case of pure intending, I now suggest that the intention simply is an all-out judgement.
     From: Donald Davidson (Intending [1978], p.99), quoted by Rowland Stout - Action 8 'Davidson's'
     A reaction: 'Pure' intending seems to be what Stout calls 'prior' intending, which is clearer. This still strikes me as obviously false. I judge that it is desirable that I make a cup of coffee, but secretly I'm hoping someone else will make it for me.
20. Action / B. Preliminaries of Action / 1. Intention to Act / b. Types of intention
We can keep Davidson's account of intentions in action, by further explaining prior intentions [Davidson, by Stout,R]
     Full Idea: Davidson's original account of intentions might still stand if we could accept that prior intentions are different in kind from intentions with which one acts.
     From: report of Donald Davidson (Problems in the Explanation of Action [1987]) by Rowland Stout - Action 8 'Davidson's'
     A reaction: Davidson says prior intention is all-out judgement of desirability. Prior intentions are more deliberate, with the other intentions as a presumed background to action. Compare Sartre's dual account of the self.
20. Action / B. Preliminaries of Action / 1. Intention to Act / c. Reducing intentions
Davidson gave up reductive accounts of intention, and said it was a primitive [Davidson, by Wilson/Schpall]
     Full Idea: Later Davidson dropped his reductive treatment of intentions (in terms of 'pro-attitudes' and other beliefs), and accepted that intentions are irreducible, and distinct from pro-attitudes.
     From: report of Donald Davidson (Intending [1978]) by Wilson,G/Schpall,S - Action 2
     A reaction: Only a philosopher would say that intentions cannot be reduced to something else. Since I have a very physicalist view of the mind, I incline to reduce them to powers and dispositions of physical matter.
20. Action / B. Preliminaries of Action / 2. Willed Action / d. Weakness of will
The causally strongest reason may not be the reason the actor judges to be best [Davidson]
     Full Idea: I defend my causal view of action by arguing that a reason that is causally strongest need not be a reason deemed by the actor to provide the strongest (best) grounds for acting.
     From: Donald Davidson (Intro to 'Essays on Actions and Events' [1980], p.xii)
     A reaction: If I smoke a cigarette against my better judgement, it is not clear to me how the desire to smoke it, which overcomes my judgement not to smoke it, counts as the causally strongest 'reason'. We seem to have two different senses of 'reason' here.
20. Action / C. Motives for Action / 2. Acting on Beliefs / a. Acting on beliefs
Acting for a reason is a combination of a pro attitude, and a belief that the action is appropriate [Davidson]
     Full Idea: Whenever someone does something for a reason he can be characterised as (a) having some sort of pro attitude towards action of a certain kind, and (b) believing (or knowing, perceiving, noticing, remembering) that his action is of that kind.
     From: Donald Davidson (Action, Reasons and Causes [1963], p.3-4), quoted by Rowland Stout - Action 3 'The belief-'
     A reaction: This is the earlier Davidson roughly endorsing the traditional belief-desire account of action. He is giving a reductive account of reasons. Deciding reasons were not reducible may have led him to property dualism.
20. Action / C. Motives for Action / 3. Acting on Reason / a. Practical reason
The notion of cause is essential to acting for reasons, intentions, agency, akrasia, and free will [Davidson]
     Full Idea: My thesis is that the ordinary notion of cause is essential to understanding what it is to act with a reason, to have an intention to act, to be an agent, to act counter to one's own best judgement, or to act freely.
     From: Donald Davidson (Intro to 'Essays on Actions and Events' [1980], p.xi)
     A reaction: I cautiously agree, particularly with idea that causation is essential to acting as an agent. Since I believe 'free will' to be a complete delusion, that part of his thesis doesn't interest me. The hard part is understanding acting for a reason.
20. Action / C. Motives for Action / 3. Acting on Reason / c. Reasons as causes
Early Davidson says intentional action is caused by reasons [Davidson, by Stout,R]
     Full Idea: In Davidson's earlier approach, intentional action requires causation by reasons.
     From: report of Donald Davidson (Action, Reasons and Causes [1963]) by Rowland Stout - Action 8 'Weakness'
     A reaction: A very Kantian idea, and one that seems to bestow causal powers on something which I take to be highly abstract. Thus Davidson was wrong (but in a nice way).
Davidson claims that what causes an action is the reason for doing it [Davidson, by Kim]
     Full Idea: Davidson defends the simple thesis that the reason for which an action is done is the one that causes it, …which means that agency is possible only if mental causation is possible.
     From: report of Donald Davidson (Action, Reasons and Causes [1963]) by Jaegwon Kim - Philosophy of Mind p.127
The best explanation of reasons as purposes for actions is that they are causal [Davidson, by Smith,M]
     Full Idea: Davidson argues that the best interpretation of the teleological character of reason explanations is an intepretation in causal terms.
     From: report of Donald Davidson (Action, Reasons and Causes [1963]) by Michael Smith - The Moral Problem 4.4
     A reaction: That is, this is the explanation of someone doing something 'because' they have this reason (rather than happening to have a reason). Smith observes that other mental states (such as beliefs) may also have this causal power.
Reasons can give purposes to actions, without actually causing them [Smith,M on Davidson]
     Full Idea: Only the Humean theory is able to make sense of reason explanation as a species of teleological explanation, and one may accept that reason explanations are teleological without accepting that they are causal.
     From: comment on Donald Davidson (Action, Reasons and Causes [1963]) by Michael Smith - The Moral Problem 4.6
     A reaction: That is, reasons can give a purpose to an action, and thereby motivate it, without actually causing it. I agree with Smith. I certainly don't (usually, at least) experience reasons as directly producing my actions. Hume says desires are needed.
Reasons must be causes when agents act 'for' reasons [Davidson, by Lowe]
     Full Idea: It can be argued (by Davidson) that far from it being the case that reasons for and causes of action are quite distinct, reasons must be causes when agents act 'for' reasons.
     From: report of Donald Davidson (Action, Reasons and Causes [1963]) by E.J. Lowe - Introduction to the Philosophy of Mind Ch.9
     A reaction: Lowe argues against this view. The rival views to Davidson would be either that reasons are no more than desires-plus-beliefs in disguise, or that the will causes actions, and strong reasons carry a great weight with the will. I like the will.
Deviant causal chain: a reason causes an action, but isn't the reason for which it was performed [Davidson, by Neta]
     Full Idea: A 'deviant causal chain' is when an agent has a reason for performing an action, and for the reason to cause the performance, without that being the reason for which the agent performed it.
     From: report of Donald Davidson (Freedom to Act [1973]) by Ram Neta - The Basing Relation II
     A reaction: Davidson's thesis is that 'reasons are causes'. This was a problem he faced. I think this discussion is now obscured by the complex and multi-layered account of action which is emerging from neuroscience.
25. Social Practice / E. Policies / 5. Education / c. Teaching
Without a teacher, the concept of 'getting things right or wrong' is meaningless [Davidson]
     Full Idea: Without a 'teacher', nothing would give content to the idea that there is a difference between getting things right and getting them wrong.
     From: Donald Davidson (Davidson on himself [1994], p.234)
     A reaction: Seems right. A group of speculators with no one in the role of 'teacher' would seem to be paralysed with uncertain (except where judgements are very obvious).
26. Natural Theory / B. Natural Kinds / 5. Reference to Natural Kinds
The cause of a usage determines meaning, but why is the microstructure of water relevant? [Davidson]
     Full Idea: While I agree that the usual cause of the use of the word determines what it means, I do not see why sameness of microstructure is necessarily the relevant similarity that determines my reference of the word 'water'.
     From: Donald Davidson (Epistemology Externalized [1990], p.198)
     A reaction: This is a problem for essentialists who build their views on semantic considerations. But the stability of what causes 'water' thoughts is the microstructure of water. However, that is an explantion of meaning, not a definition of it.
26. Natural Theory / C. Causation / 1. Causation
Distinguish causation, which is in the world, from explanations, which depend on descriptions [Davidson, by Schaffer,J]
     Full Idea: Davidson distinguishes between causation, an extensional relation that holds between coarse events, and explanation, which is an intensional relation that holds between the coarse events under a description.
     From: report of Donald Davidson (Causal Relations [1967]) by Jonathan Schaffer - The Metaphysics of Causation 1.2
     A reaction: I'm unclear why everything has to be so coarse, when reality and causal events seem to fine-grained, but the distinction strikes me as good. Explanations relate to human understanding and human interests. Cf. Anscombe's view.
26. Natural Theory / C. Causation / 8. Particular Causation / b. Causal relata
Either facts, or highly unspecific events, serve better as causes than concrete events [Field,H on Davidson]
     Full Idea: It is best to avoid Davidson's view that only quite concrete events can serve as causes; we should either say that facts as well as events can serve as causes; or that the events can be highly unspecific, including 'omissions'.
     From: comment on Donald Davidson (Causal Relations [1967]) by Hartry Field - Causation in a Physical World 1
     A reaction: Something NOT happening might be the main cause of an effect (drought), or an effect may mainly result from a situation rather than an event (famine).
Causation is either between events, or between descriptions of events [Davidson, by Maslin]
     Full Idea: According to Davidson analyses of causality proceed at two different levels: at the lower level it holds between events regardless of how they are described; higher level explanations hold between descriptions of events, which pick out properties.
     From: report of Donald Davidson (Mental Events [1970]) by Keith T. Maslin - Introduction to the Philosophy of Mind 7.4
Whether an event is a causal explanation depends on how it is described [Davidson, by Maslin]
     Full Idea: Davidson says causal explanations hold between descriptions of events and not between the events themselves, so the possibility of events as explanations depends on how they are described (e.g. a wind collapsing a bridge).
     From: report of Donald Davidson (Mental Events [1970]) by Keith T. Maslin - Introduction to the Philosophy of Mind 7.4
26. Natural Theory / C. Causation / 8. Particular Causation / c. Conditions of causation
Full descriptions can demonstrate sufficiency of cause, but not necessity [Davidson]
     Full Idea: The fuller we make the description of a cause, the better our chances of demonstrating that it was sufficient (as described) to produce the effect, and the worse our chances of demonstrating that it was necessary. (For the effect, it is the opposite).
     From: Donald Davidson (Causal Relations [1967], §3)
     A reaction: If the fullness of description is relevant, this suggests that Davidson is focusing on human explanations, rather than on the ontology of causation. If the cause IS necessary, why wouldn't a better description make that clearer?
26. Natural Theory / C. Causation / 9. General Causation / b. Nomological causation
A singular causal statement is true if it is held to fall under a law [Davidson, by Psillos]
     Full Idea: For Davidson, what makes singular causal statements true is the existence of some regularities or laws. All causal is nomological: c causes e iff there is a law that connects events like c with events like e.
     From: report of Donald Davidson (Causal Relations [1967]) by Stathis Psillos - Causation and Explanation §2.6
     A reaction: I wonder if the cart is before the horse here. Scriven says this is just a claim that there are "phantom laws". It is the Humean view of causation, but surely the laws come after the causation, so can't be used to explain it?
Cause and effect relations between events must follow strict laws [Davidson]
     Full Idea: If two events are related as cause and effect, there is a strict law under which they may be subsumed.
     From: Donald Davidson (Davidson on himself [1994], p.231)
     A reaction: Davidson admits that this is open to challenge (though Hume and Kant supported it). It does seem to be central to our understanding of nature.
