62 ideas

1. Philosophy / D. Nature of Philosophy / 7. Despair over Philosophy
Philosophers are good at denying the obvious [Hawley]
     Full Idea: Philosophers are skilled at resisting even the most inviting thoughts.
     From: Katherine Hawley (How Things Persist [2001], 5)
     A reaction: Not exactly 'despair', but it does show how far philosophers are able to stray from common sense. Monads, real possible worlds, real sets… Thomas Reid, the philosopher of common sense, might be the antidote.
1. Philosophy / G. Scientific Philosophy / 3. Scientism
A culture needs to admit that knowledge is more extensive than just 'science' [Putnam]
     Full Idea: The acknowledgement that the sphere of knowledge is wider than the sphere of 'science' seems to me to be a cultural necessity if we are to arrive at a sane and human view of ourselves or of science.
     From: Hilary Putnam (Meaning and the Moral Sciences [1978], Intro)
     A reaction: A very nice remark, with which I intuitively agree, but then you are left with the problem of explaining how something can qualify as knowledge when it can't pass the stringent tests of science. How wide to we spread, and why?
'True' and 'refers' cannot be made scientically precise, but are fundamental to science [Putnam]
     Full Idea: Some non-scientific knowledge is presupposed by science; for example, I have been arguing that 'refers' and 'true' cannot be made scientifically precise; yet truth is a fundamental term in logic - a precise science.
     From: Hilary Putnam (Meaning and the Moral Sciences [1978], Lec VI)
     A reaction: We might ask whether we 'know' what 'true' and 'refers' mean, as opposed to being able to use them. If their usage doesn't count as knowledge, then we could still end up with all actual knowledge being somehow 'scientific'.
3. Truth / A. Truth Problems / 1. Truth
'The rug is green' might be warrantedly assertible even though the rug is not green [Putnam]
     Full Idea: 'The rug is green' might be warrantedly assertible even though the rug is not green.
     From: Hilary Putnam (Meaning and the Moral Sciences [1978], Pt Three)
     A reaction: The word 'warranted' seems to be ambiguous in modern philosophy. See Idea 6150. There seem to be internalist and externalist versions. It seems clear to say that a belief could be well-justified and yet false.
3. Truth / C. Correspondence Truth / 1. Correspondence Truth
We need the correspondence theory of truth to understand language and science [Putnam]
     Full Idea: A correspondence theory of truth is needed to understand how language works, and how science works.
     From: Hilary Putnam (Meaning and the Moral Sciences [1978], Intro)
     A reaction: Putnam retreated from this position to a more pragmatic one later on, but all my sympathies are with the present view, despite being repeatedly told by modern philosophers that I am wrong. See McGinn (Idea 6085) and Searle (Idea 3508).
3. Truth / C. Correspondence Truth / 3. Correspondence Truth critique
Correspondence between concepts and unconceptualised reality is impossible [Putnam]
     Full Idea: The great nineteenth century argument against the correspondence theory of truth was that one cannot think of truth as correspondence to facts (or 'reality') because one would need to compare concepts directly with unconceptualised reality.
     From: Hilary Putnam (Meaning and the Moral Sciences [1978], Pt Three)
     A reaction: Presumably the criticism was offered by idealists, who preferred a coherence theory. The defence is to say that there is a confusion here between a concept and the contents of a concept. The contents of a concept are designed to be facts.
3. Truth / F. Semantic Truth / 2. Semantic Truth
In Tarski's definition, you understand 'true' if you accept the notions of the object language [Putnam]
     Full Idea: Anyone who accepts the notions of whatever object language is in question - and this can be chosen arbitrarily - can also understand 'true' as defined by Tarski for that object language.
     From: Hilary Putnam (Meaning and the Moral Sciences [1978], Intro)
     A reaction: Thus if we say "'snow is white' is true iff snow is white", then if you 'accept the notion' that snow is white in English, you understand what 'true' means. This seems to leave you with the meaning of 'snow is white' being its truth conditions.
Tarski has given a correct account of the formal logic of 'true', but there is more to the concept [Putnam]
     Full Idea: What Tarski has done is to give us a perfectly correct account of the formal logic of the concept 'true', but the formal logic of the concept is not all there is to the notion of truth.
     From: Hilary Putnam (Meaning and the Moral Sciences [1978], Intro)
     A reaction: I find this refreshing. A lot of modern philosophers seem to think that truth is no longer an interesting philosophical topic, because deflationary accounts have sidelined it, but I take the concept to be at the heart of metaphysics.
Only Tarski has found a way to define 'true' [Putnam]
     Full Idea: There is only one way anyone knows how to define 'true' and that is Tarski's way.
     From: Hilary Putnam (Meaning and the Moral Sciences [1978], Lec II.5)
     A reaction: However, Davidson wrote a paper called 'On the Folly of Trying to Define Truth', which seems to reject even Tarski. Also bear in mind Putnam's earlier remark (Idea 6265) that there is more to truth than Tarski's definition. Just take 'true' as primitive.
5. Theory of Logic / F. Referring in Logic / 1. Naming / b. Names as descriptive
Part of the sense of a proper name is a criterion of the thing's identity [Hawley]
     Full Idea: A Fregean dictum is that part of the sense of proper name is a criterion of identity for the thing in question.
     From: Katherine Hawley (How Things Persist [2001], 3.8)
     A reaction: [She quotes Dummett 1981:545] We are asked to choose between this and the Kripke rigid/dubbing/causal account, with effectively no content.
7. Existence / C. Structure of Existence / 5. Supervenience / d. Humean supervenience
A homogeneous rotating disc should be undetectable according to Humean supervenience [Hawley]
     Full Idea: Imagine a perfectly homogeneous non-atomistic disc. A record of all the non-relational information about the world at that moment will not reveal whether the disc is rotating about a vertical axis through. This tells against Humean supervenience.
     From: Katherine Hawley (How Things Persist [2001], 3.2)
     A reaction: [Armstrong 1980 originated this, and it is famously discussed by Kripke in lectures] There will, of course, be dispositions present because of the rotation, but Lewis excludes any such modal truths.
7. Existence / D. Theories of Reality / 2. Realism
Realism is a theory, which explains the convergence of science and the success of language [Putnam]
     Full Idea: Realism is an empirical theory; it explains the convergence of scientific theories, where earlier theories are often limiting cases of later theories (which is why theoretical terms preserve their reference); and it explains the success of language.
     From: Hilary Putnam (Meaning and the Moral Sciences [1978], Pt Four)
     A reaction: I agree. Personally, I think of Plato's Theory of Forms and all religions as empirical theories. The response from anti-realists is generally to undermine confidence in the evidence which these 'empirical theories' are said to explain.
7. Existence / D. Theories of Reality / 10. Vagueness / b. Vagueness of reality
Non-linguistic things cannot be indeterminate, because they don't have truth-values at all [Hawley]
     Full Idea: Non-linguistic objects, properties, and states of affairs cannot be indeterminate because they cannot have determinate truth-values either. No cloud is indeterminate, just as no cloud is either determinately true or determinately false.
     From: Katherine Hawley (How Things Persist [2001], 4.1)
     A reaction: If vagueness must be linguistic, this means animals can never experience it, which I doubt. Presumably 'this is a cloud' is only made vague by the vagueness of the object, rather than by the vagueness of the sentence?
Maybe for the world to be vague, it must be vague in its foundations? [Hawley]
     Full Idea: There is a question of whether there must be 'vagueness all the way down' for the world to be vague. One view is that if there is a base level of precisely describably facts, upon which all the others supervene, then the world is not really vague.
     From: Katherine Hawley (How Things Persist [2001], 4.5)
     A reaction: My understanding of the physics is that it is non-vague all the way down, and then you get to the base level which is hopelessly vague!
7. Existence / D. Theories of Reality / 10. Vagueness / c. Vagueness as ignorance
Epistemic vagueness seems right in the case of persons [Hawley]
     Full Idea: The epistemic account of vagueness is particularly attractive where persons are concerned.
     From: Katherine Hawley (How Things Persist [2001], 4.14)
     A reaction: You'll have to see her text for details. Interesting that there might be different views of what vagueness is for different cases. Or putting it another way, absolutely everything (said, thought, existing or done) might be vague in some way!
7. Existence / D. Theories of Reality / 10. Vagueness / f. Supervaluation for vagueness
Supervaluation refers to one vaguely specified thing, through satisfaction by everything in some range [Hawley]
     Full Idea: Supervaluationists take a present-tense predication as concerning a single, but vaguely specified, moment. …It is indeterminate which of a range of moments enters into the truth conditions, but it is true if satisfied by every member of the range.
     From: Katherine Hawley (How Things Persist [2001], 2.7)
     A reaction: She is discussing stage theory, but this is a helpful clarification of the idea of supervaluation. Something can be satisfied by a whole bunch of values, even though you are not sure which one.
Supervaluationism takes what the truth-value would have been if indecision was resolved [Hawley]
     Full Idea: A supervaluationist approach involves consideration of what the truth value of the utterance would have been if semantic indecision had been resolved in this way or that.
     From: Katherine Hawley (How Things Persist [2001], 4.1)
     A reaction: At last, a lovely account of supervaluation in plain English that anyone can understand! Why don't they all do that? Well, done Katherine Hawley! ['semantic indecision' is uncertainty about what your words mean!]
8. Modes of Existence / B. Properties / 1. Nature of Properties
Maybe the only properties are basic ones like charge, mass and spin [Hawley]
     Full Idea: Some philosophers suspect that properties are few and far between, that there are only properties like charge, mass, spin, and so on.
     From: Katherine Hawley (How Things Persist [2001], 5.1)
     A reaction: I think properties are very sparse, and mainly consist of physical powers, but I am not sure what I think of this. It may be 'mere semantics'. Complex properties still seem to be properties. Powers combine to make properties, I suggest.
9. Objects / A. Existence of Objects / 1. Physical Objects
An object is 'natural' if its stages are linked by certain non-supervenient relations [Hawley]
     Full Idea: I suggest that our distinction between natural and unnatural (gerrymandered) objects corresponds to a distinction between series of stages which are and are not linked by certain non-supervenient relations.
     From: Katherine Hawley (How Things Persist [2001], 5.5)
     A reaction: See Idea 16213 for the nature of these 'relations'. I don't understand how an abstraction (as I take it) like a relation can unify a physical object. A trout-turkey is unified by a relation of some sort. Hawley defends Stage Theory.
9. Objects / B. Unity of Objects / 3. Unity Problems / b. Cat and its tail
Are sortals spatially maximal - so no cat part is allowed to be a cat? [Hawley]
     Full Idea: Many philosophers believe that sortal predicates are spatially maximal - for example, that no cat can be a proper spatial part of a cat.
     From: Katherine Hawley (How Things Persist [2001], 2.1)
     A reaction: This sounds reasonable until you cut the tail off a cat. Presumably what remains is a cat? So presumably that smaller part was always a cat? Only essentialism can make sense of this! You can't just invent rules for sortals.
9. Objects / B. Unity of Objects / 3. Unity Problems / c. Statue and clay
The modal features of statue and lump are disputed; when does it stop being that statue? [Hawley]
     Full Idea: It is difficult to establish a consensus about the modal features of the statue and the lump. Could that statue be made of a different lump? Could that statue of Goliath have been spherical? Not a realistic statue of Goliath, but still the same statue?
     From: Katherine Hawley (How Things Persist [2001], 6)
     A reaction: The problem is with a wild wacky sculptor, who might say it is a statue of Goliath no matter what shape the lump takes. 'Goliath had a spherical character'. Sometimes we will say (pace Evans) it is 'roughly identical' to the original statue.
Perdurantists can adopt counterpart theory, to explain modal differences of identical part-sums [Hawley]
     Full Idea: Perdurance theory claims that lumps and statues differ modally whilst always being made of the same parts. A natural way to make this less mysterious is for perdurantists to adopt counterpart theory, where objects in different worlds are never identical.
     From: Katherine Hawley (How Things Persist [2001], 6.2)
     A reaction: This, of course, is exactly the system created by David Lewis. Personally I rather like counterparts, but perdurance seems a tad crazy.
9. Objects / B. Unity of Objects / 3. Unity Problems / e. Vague objects
Vagueness is either in our knowledge, in our talk, or in reality [Hawley]
     Full Idea: There are three main views of vagueness: the Epistemic view says we talk precisely, but don't know what we talk precisely about; the Semantic view is that it is loose talk, or semantic indecision; the Ontic view says it is part of how the world is.
     From: Katherine Hawley (How Things Persist [2001], 4.1)
     A reaction: [My summary of two paragraphs] She associates Williamson with the first view, Lewis with the second, and Van Inwagen with the third.
Indeterminacy in objects and in properties are not distinct cases [Hawley]
     Full Idea: There is no important distinction to be drawn between cases where indeterminacy is due to the object involved and cases where indeterminacy is due to the property involved.
     From: Katherine Hawley (How Things Persist [2001], 4.2)
     A reaction: You could always paraphrase the object's situation propertywise, or the property's situation objectwise. 'His baldness is indeterminate'; 'where does the mountainous terrain end?'
9. Objects / C. Structure of Objects / 6. Constitution of an Object
The constitution theory is endurantism plus more than one object in a place [Hawley]
     Full Idea: Constitution theorists are endurance theorists who believe that there can be more than one object exactly occupying a spatial region at a certain moment.
     From: Katherine Hawley (How Things Persist [2001], 5.1)
     A reaction: I increasingly think that this is a ridiculous view. The constitution of an object isn't a further object. A constitution is a necessary requirement for a physical object. Hylomorphism! Constitutions can't be separate - they must constitute something!
Constitution theory needs sortal properties like 'being a sweater' to distinguish it from its thread [Hawley]
     Full Idea: Constitution theorists need to posit sortal properties of 'being a thread' or 'being a sweater', as grounds for the differences betwween the sweater and the thread that constitutes it.
     From: Katherine Hawley (How Things Persist [2001], 5.1)
     A reaction: This is further grounds for thinking the constitution view ridiculous, because there are no such properties. 'Being a sweater' is a category, which something belongs in if it has all the properties of a sweater. The final property triggers sweaterhood.
If the constitution view says thread and sweater are two things, why do we talk of one thing? [Hawley]
     Full Idea: The constitution theorists, who claim that the sweater and the thread are different things, should offer some explanation of why we tend to say that there is just one thing there. They must simply claim that we 'do not count by identity'.
     From: Katherine Hawley (How Things Persist [2001], 5.8)
     A reaction: Her example is a sweater knitted from a single piece of thread. Presumably we could count by sortal identity, so there is one thread here, and there is one sweater here. We just can't add the two together. No ontological arithmetic.
9. Objects / E. Objects over Time / 2. Objects that Change
'Adverbialism' explains change by saying an object has-at-some-time a given property [Hawley]
     Full Idea: Another strategy for the problem of change says that instantiation - the having of properties - is time-indexed, or relative to times, although properties themselves are not. This 'adverbialism' says that object has-at-t some property.
     From: Katherine Hawley (How Things Persist [2001], 1.5)
     A reaction: [She cites Johnson, Lowe and Haslanger for this] Promising. The question is whether the time index is attached to the object, to the property, or to the instantiation. The middle one is wrong. There aren't two properties - green-at-t1 and green-at-t2.
Presentism solves the change problem: the green banana ceases, so can't 'relate' to the yellow one [Hawley]
     Full Idea: Adopting presentism solves the problem of change, since it means that, once the banana is yellow, there just is no green banana, and the question of the relationship between yesterday's green banana and today's yellow one therefore does not arise.
     From: Katherine Hawley (How Things Persist [2001], 1.7)
     A reaction: Change remains kind of odd, but it is no longer the puzzlement of two things being the same when they are admitted to be different. There is only ever one thing. This is my preferred account, I think. I certainly hope past bananas don't exist.
The problem of change arises if there must be 'identity' of a thing over time [Hawley]
     Full Idea: It is the insistence on identity between objects wholly present at different times which gives rise to the problem of change.
     From: Katherine Hawley (How Things Persist [2001], 2.2)
     A reaction: My solution is to say things are the 'same', in a slightly loose non-transitive way, rather than formally identical, which is a concept from maths, not from reality.
9. Objects / E. Objects over Time / 3. Three-Dimensionalism
Endurance theory can relate properties to times, or timed instantiations to properties [Hawley]
     Full Idea: Endurance theory might claim a banana stands (atemporally) in different relations to different times (being-green-at to Monday), ..or has different instantiation relations to different properties (instantiates-on-Monday to being green).
     From: Katherine Hawley (How Things Persist [2001], 1.3)
     A reaction: She suggests that the first approach is more plausible for endurantists. I think she is right (assuming these are the only two options). Monday awaits a banana, but yellow doesn't.
Endurance is a sophisticated theory, covering properties, instantiation and time [Hawley]
     Full Idea: Endurance theory is not just a default 'no-theory' theory, for it must incorporate a sophisticated account of properties and instantiation, and requires a certain view of time if it is even to be formulable.
     From: Katherine Hawley (How Things Persist [2001], 1.8)
     A reaction: A bit odd to claim it is a sophisticated theory when it is held (at least in our culture) by absolutely everyone apart from a few philosophers and physicists. The sophistication may come with trying to describe it using current metaphysical vocabulary.
9. Objects / E. Objects over Time / 4. Four-Dimensionalism
How does perdurance theory explain our concern for our own future selves? [Hawley]
     Full Idea: A question for perdurance theory is whether it can account for the special concern we feel for our own future selves.
     From: Katherine Hawley (How Things Persist [2001], 1.8)
     A reaction: That is one of those questions that begins to look very mysterious whatever your theory. I favour endurantism, but me next year looks a very remote person for me to be concerned about, in comparison with the people around me now.
Perdurance needs an atemporal perspective, to say that the object 'has' different temporal parts [Hawley]
     Full Idea: Perdurance relies on our having an 'atemporal' perspective from which we can truly say a banana has both yellow and green parts, where this 'has' is not in the present tense. ..Perdurance theory cannot be expressed straightforwardly in the present tense.
     From: Katherine Hawley (How Things Persist [2001], 1.2)
     A reaction: This seems to require the tenseless B-series view of time. It seems to need a tenseless view of the past, but what does it have to say about the future?
If an object is the sum of all of its temporal parts, its mass is staggeringly large! [Hawley]
     Full Idea: The mass of an object is the sum of its nonoverlapping parts. Analogy would suggest that a persisting banana has, atemporally speaking, a mass that is the sum of all the masses of the 100g temporal parts, a worryingly large figure.
     From: Katherine Hawley (How Things Persist [2001], 2.1)
     A reaction: This is an objection to the Perdurance view that an object is the sum of all of its temporal parts. Their duration tends towards instantaneous, so the aggregate mass tends towards infinity. She says they should deny atemporal mass.
Perdurance says things are sums of stages; Stage Theory says each stage is the thing [Hawley]
     Full Idea: According to Perdurance Theory, it is long-lived sums of stages which are tennis balls, whereas according to Stage Theory, it is the stages themselves which are tennis balls.
     From: Katherine Hawley (How Things Persist [2001], 2.2)
     A reaction: These seem to be the two options if you are a four-dimensionalist, though Fine says you could be a weird three-dimensionalist and choose stage theory.
If a life is essentially the sum of its temporal parts, it couldn't be shorter or longer than it was? [Hawley]
     Full Idea: It seems that perdurance theory should identify Descartes with the sum of his temporal parts, but that means Descartes essentially lived for 54 years, which seems absurd, as he could have lived longer or less long than he in fact did.
     From: Katherine Hawley (How Things Persist [2001], 6.10)
     A reaction: [She credits Van Inwagen with this] I'm not clear why a counterpart of Descartes could not have a shorter or longer sum of parts, and still be Descartes. If the sum is rigidly designated, that is a problem for endurance too.
9. Objects / E. Objects over Time / 5. Temporal Parts
Stages must be as fine-grained in length as change itself, so any change is a new stage [Hawley]
     Full Idea: To account for change, stages and temporal parts must be as fine-grained as change: a material thing must have as many stages or parts as it is in incompatible states during its lifetime.
     From: Katherine Hawley (How Things Persist [2001], 2.4)
     A reaction: There seems to be a dilemma for stages here, of being so fat that they are divisible and change, or so thin that they barely exist. Lose-lose, I'd say.
Stage Theory seems to miss out the link between stages of the same object [Hawley]
     Full Idea: The first worry for Stage Theory is that many present stages are bananas, and many stages tomorrow are bananas, but this seems to omit the important fact that some of those stages are intimately linked, that certain stages are the same banana.
     From: Katherine Hawley (How Things Persist [2001], 2.3)
     A reaction: Hawley has a theory to do with external relations, which I didn't find very persuasive. Just to say stages have a 'relation' seems too abstract. Stages of disparate things can also have 'relations', but presumably the wrong sort.
Stage Theory says every stage is a distinct object, which gives too many objects [Hawley]
     Full Idea: The second worry for Stage Theory is that there are far too many bananas in the world on this account.
     From: Katherine Hawley (How Things Persist [2001], 2.3)
     A reaction: The point is that each (instantaneous) stage is considered to be a whole banana (as opposed to one sum of all the stages of the banana, in the Perdurance view). A pretty serious problem, which she tries to deal with.
An isolated stage can't be a banana (which involves suitable relations to other stages) [Hawley]
     Full Idea: A single isolated stage could not be a banana, because in order to be a banana a stage must be suitably related to other stages with appropriate properties.
     From: Katherine Hawley (How Things Persist [2001], 3.4.1)
     A reaction: This seems at odds with the claim that each stage is the whole thing (rather than the long temporal 'worm' of perdurance theory). Isolated stages are instantaneous, so can't be anything, really. Her 'relations' seem hand-wavy to me. Connections?
Stages of one thing are related by extrinsic counterfactual and causal relations [Hawley]
     Full Idea: I claim that there are relations between the distinct stages of a persisting object which are not determined by the intrinsic properties of those stages. …The later stages depend, counterfactually and causally, upon the earlier stages.
     From: Katherine Hawley (How Things Persist [2001], 3.5)
     A reaction: This is the heart of her theory. How can there be a causal link between two stages which is not the result of intrinsic properties of the stages? This begins to sound like Malebranche's Occasionalism.
The stages of Stage Theory seem too thin to populate the world, or to be referred to [Hawley]
     Full Idea: A third worry for Stage Theory is that the momentary stages themselves are just too thin to populate the world, and too thin to be the objects of reference.
     From: Katherine Hawley (How Things Persist [2001], 2.3)
     A reaction: Her three objections to her own theory add up to sufficient to refute it, in my view, though a large chunk of her book is spent trying to refute the objections.
9. Objects / F. Identity among Objects / 8. Leibniz's Law
If two things might be identical, there can't be something true of one and false of the other [Hawley]
     Full Idea: We can call the 'transference principle' the claim that if it is indeterminate whether two objects are identical, then nothing determinately true of one can be determinately false of the other.
     From: Katherine Hawley (How Things Persist [2001], 4.9)
     A reaction: The point is that Leibniz's Law could immediately be invoked to show there is no possibility of their identity.
10. Modality / E. Possible worlds / 3. Transworld Objects / c. Counterparts
To decide whether something is a counterpart, we need to specify a relevant sortal concept [Hawley]
     Full Idea: When asked whether a possible object is a counterpart of something, we need to specify which sortal we are interested in.
     From: Katherine Hawley (How Things Persist [2001], 6.2)
     A reaction: The compares this to the 'respect' in which two things are similar. For example, what would count as a counterpart of the current British Prime Minister? De re or de dicto reference?
12. Knowledge Sources / A. A Priori Knowledge / 8. A Priori as Analytic
If a tautology is immune from revision, why would that make it true? [Putnam]
     Full Idea: If we held, say, 'All unmarried men are unmarried' as absolutely immune from revision, why would this make it true?
     From: Hilary Putnam (Meaning and the Moral Sciences [1978], Pt Four)
     A reaction: A very nice question. Like most American philosophers, Putnam accepts Quine's attack on the unrevisability of analytic truths. His point here is that defenders of analytic truths are probably desperate to preserve basic truths, but it won't work.
13. Knowledge Criteria / C. External Justification / 7. Testimony
Knowledge depends on believing others, which must be innate, as inferences are not strong enough [Putnam]
     Full Idea: Our ability to picture how people are likely to respond may well be innate; indeed, our disposition to believe what other people tell us (which is fundamental to knowledge) could hardly be an inference, as that isn’t good enough for knowledge.
     From: Hilary Putnam (Meaning and the Moral Sciences [1978], Lec VI)
     A reaction: An interesting claim. There could be an intermediate situation, which is a hard-wired non-conscious inference. When dismantled, the 'innate' brain circuits for assessing testimony could turn out to work on logic and evidence.
Empathy may not give knowledge, but it can give plausibility or right opinion [Putnam]
     Full Idea: Empathy with others may give less than 'Knowledge', but it gives more than mere logical or physical possibility; it gives plausibility, or (to revive Platonic terminology) it provides 'right opinion'.
     From: Hilary Putnam (Meaning and the Moral Sciences [1978], Lec VI)
     A reaction: See Ideas 174 and 2140 for Plato. Putnam is exploring areas of knowledge outside the limits of strict science. Behind this claim seems to lie the Principle of Charity (3971), but a gang of systematic liars (e.g. evil students) would be a problem case.
14. Science / D. Explanation / 4. Explanation Doubts / a. Explanation as pragmatic
You can't decide which explanations are good if you don't attend to the interest-relative aspects [Putnam]
     Full Idea: Explanation is an interest-relative notion …explanation has to be partly a pragmatic concept. To regard the 'pragmatics' of explanation as no part of the concept is to abdicate the job of figuring out what makes an explanation good.
     From: Hilary Putnam (Meaning and the Moral Sciences [1978], p. 41-2), quoted by David-Hillel Ruben - Explaining Explanation Ch 1
     A reaction: I suppose this is just obvious, depending on how far you want to take the 'interest-relative' bit. If a fool is fobbed off with a trivial explanation, there must be some non-relative criterion for assessing that.
16. Persons / D. Continuity of the Self / 5. Concerns of the Self
On any theory of self, it is hard to explain why we should care about our future selves [Hawley]
     Full Idea: It is rather difficult to say why one should care about one's future self, even on an endurance theory account of the self.
     From: Katherine Hawley (How Things Persist [2001], 3.9)
     A reaction: A nice passing remark, that strikes me forcibly as one of those basic mysteries of experience that philosophers can only gawp at, and have no theory to offer.
19. Language / A. Nature of Meaning / 1. Meaning
Theory of meaning presupposes theory of understanding and reference [Putnam]
     Full Idea: Theory of meaning presupposes theory of understanding and reference.
     From: Hilary Putnam (Meaning and the Moral Sciences [1978], Pt Four)
     A reaction: How can you have a theory of understanding without a meaning that requires to be understood? Personally I think about the minds of small animals when pondering this, and that seems to put reference and truth at the front of the queue.
19. Language / A. Nature of Meaning / 4. Meaning as Truth-Conditions
Truth conditions can't explain understanding a sentence, because that in turn needs explanation [Putnam]
     Full Idea: You can't treat understanding a sentence as knowing its truth conditions, because it then becomes unintelligible what that knowledge in turn consists in.
     From: Hilary Putnam (Meaning and the Moral Sciences [1978], Pt Four)
     A reaction: The implication, I take it, is circularity; how can you specify truth conditions if you don't understand sentences? Putnam here agrees with Dummett that verification must be involved. Something has to be taken as axiomatic in all this.
We should reject the view that truth is prior to meaning [Putnam]
     Full Idea: I am suggesting that we reject the view that truth (based on the semantic theory) is prior to meaning.
     From: Hilary Putnam (Meaning and the Moral Sciences [1978], Pt Three)
     A reaction: It is a nice question which of truth or meaning has logical priority. One might start by speculating about how and why animals think. A moth attracted to flame is probably working on truth without much that could be called 'meaning'.
19. Language / B. Reference / 1. Reference theories
How reference is specified is not what reference is [Putnam]
     Full Idea: A theory of how reference is specified isn't a theory of what reference is.
     From: Hilary Putnam (Meaning and the Moral Sciences [1978], Lec V)
     A reaction: A simple and important point. We may achieve reference by naming, describing, grunting or pointing, but the question is, what have we achieved when we get there?
19. Language / B. Reference / 4. Descriptive Reference / b. Reference by description
The claim that scientific terms are incommensurable can be blocked if scientific terms are not descriptions [Putnam]
     Full Idea: The line of reasoning of Kuhn and Feyerabend can be blocked by arguing (as I have in various places, and as Saul Kripke has) that scientific terms are not synonymous with descriptions.
     From: Hilary Putnam (Meaning and the Moral Sciences [1978], Lec II.2)
     A reaction: A nice clear statement of the motivation for creating the causal theory of reference. See Idea 6162. We could still go back and ask whether we could block scientific relativism by rethinking how descriptions work, instead of abandoning them.
19. Language / F. Communication / 4. Private Language
A private language could work with reference and beliefs, and wouldn't need meaning [Putnam]
     Full Idea: A language made up and used by a being who belonged to no community would have no need for such a concept as the 'meaning' of a term. To state the reference of each term and what the language speaker believes is to tell the whole story.
     From: Hilary Putnam (Meaning and the Moral Sciences [1978], Pt Three)
     A reaction: A subtle response to Wittgenstein's claim (e.g. Ideas 4152,4158), but I am not sure what Putnam means. I would have thought that beliefs had to be embodied in propositions. They may not need 'meaning' quite as urgently as sentences, but still…
19. Language / F. Communication / 6. Interpreting Language / b. Indeterminate translation
The correct translation is the one that explains the speaker's behaviour [Putnam]
     Full Idea: What it is to be a correct translation is to be the translation that best explains the behaviour of the speaker.
     From: Hilary Putnam (Meaning and the Moral Sciences [1978], Lec III)
     A reaction: This seems fairly close to Quine, but rather puzzlingly uses the word 'correct'. If our criteria of translation are purely behavioural, there is no way we can be correct after one word ('gavagai'), so at what point does it become 'correct'?
Language maps the world in many ways (because it maps onto other languages in many ways) [Putnam]
     Full Idea: We could say that the language has more than one correct way of being mapped onto the world (it must, since it has more than one way of being correctly mapped onto a language which is itself correctly mapped onto the world).
     From: Hilary Putnam (Meaning and the Moral Sciences [1978], Pt Four)
     A reaction: This spells out nicely the significance of Quine's 'indeterminacy of translation'. Others have pointed out that the fact that language maps onto world in many ways need not be anti-realist; the world is endless, and language is limited.
19. Language / F. Communication / 6. Interpreting Language / c. Principle of charity
You can't say 'most speaker's beliefs are true'; in some areas this is not so, and you can't count beliefs [Putnam]
     Full Idea: The maxim that 'most of a speaker's beliefs are true' as an a priori principle governing radical translation seems to me to go too far; first, I don't know how to count beliefs; second, most people's beliefs on some topics (philosophy) are probably false.
     From: Hilary Putnam (Meaning and the Moral Sciences [1978], Pt Three)
     A reaction: Putnam prefers a pragmatic view, where charity is applicable if behaviour is involved. Philosophy is too purely theoretical. The extent to which Charity should apply in philosophy seminars is a nice question, which all students should test in practice.
26. Natural Theory / C. Causation / 9. General Causation / c. Counterfactual causation
Causation is nothing more than the counterfactuals it grounds? [Hawley]
     Full Idea: Counterfactual accounts of causation say that a causal connection is exhausted by the counterfactuals it appears to ground.
     From: Katherine Hawley (How Things Persist [2001], 3.5)
     A reaction: I am bewildered as to how this became a respectable view in philosophy. I quite understand that this might exhaust the 'logic' of causal relations. Presumably you can have counterfactuals in mathematics which are not causal?
27. Natural Reality / D. Time / 3. Parts of Time / b. Instants
Time could be discrete (like integers) or dense (rationals) or continuous (reals) [Hawley]
     Full Idea: There seem to be three possible ways for time to be fine-grained. The ordering of instants could be discrete (like the integers), dense (like the rational numbers) or continuous (like the real numbers).
     From: Katherine Hawley (How Things Persist [2001], 2.5)
     A reaction: She seems to assume that time must be 'grained', but I would take the continuous view to imply that there is no grain at all (which is bad news for her version of stage theory).
28. God / B. Proving God / 2. Proofs of Reason / a. Ontological Proof
The concept of an existing thing must contain more than the concept of a non-existing thing [Leibniz]
     Full Idea: There must be more in the concept of a thing which exists than in that of one which does not exist.
     From: Gottfried Leibniz (On the Principles of Indiscernibles [1696], p.134)
