2. Reason / A. Nature of Reason / 6. Coherence
If the only aim was consistent beliefs then new evidence and experiments would be irrelevant [Goldman]
     Full Idea: If mere consistency is our aim in achieving a coherent set of beliefs, then new evidence and experiments are irrelevant.
     From: Alvin I. Goldman (The Internalist Conception of Justification [1980], §VIII)
     A reaction: An important reminder. What epistemic duty requires us to attend to anomalous observations, instead of sweeping them under the carpet?
2. Reason / B. Laws of Thought / 6. Ockham's Razor
Epistemological Ockham's Razor demands good reasons, but the ontological version says reality is simple [Moreland]
     Full Idea: Ockham's Razor has an epistemological version, which says we should not multiply existences or explanations without adequate reason, and an ontological version, which says reality is simple, and so a simpler ontology represents it more accurately.
     From: J.P. Moreland (Universals [2001], Ch.2)
     A reaction: A nice distinction. Is it reality which is simple, or us? One shouldn't write off the ontological version. If one explanation is simpler than the others, there may be a reason in nature for that.
5. Theory of Logic / F. Referring in Logic / 2. Descriptions / c. Theory of definite descriptions
The theory of descriptions supports internalism, since they are thinkable when the object is non-existent [Crane]
     Full Idea: The theory of descriptions gives a model of internalist intentionality, in that it describes cases where the thinkability of a belief does not depend on the existence of a specific object.
     From: Tim Crane (Elements of Mind [2001], 4.36)
     A reaction: So what do externalists say about the theory? Surely a reference to 'water' can't entail the existence of water?
6. Mathematics / A. Nature of Mathematics / 4. Using Numbers / c. Counting procedure
Children may have three innate principles which enable them to learn to count [Goldman]
     Full Idea: It has been proposed (on the basis of observations) that young children have three innate principles of counting - one-to-one correspondence of number to item, stable order for numbers, and cardinality (which labels the nth item counted).
     From: Alvin I. Goldman (Phil Applications of Cognitive Science [1993], p.60)
     A reaction: I like the idea of observed patterns as central (which is the one-to-one principle). But the other two principles are plausible, and show why pure empiricism won't work.
6. Mathematics / C. Sources of Mathematics / 4. Mathematical Empiricism / a. Mathematical empiricism
Rat behaviour reveals a considerable ability to count [Goldman]
     Full Idea: Rats can determine the number of times they have pressed a lever up to at least twenty-four presses,…and can consistently turn down the fifth tunnel on the left in a maze.
     From: Alvin I. Goldman (Phil Applications of Cognitive Science [1993], p.58)
     A reaction: This seems to encourage an empirical view of maths (pattern recognition?) rather than a Platonic one. Or numbers are innate in rat brains?
7. Existence / C. Structure of Existence / 5. Supervenience / a. Nature of supervenience
Aesthetic properties of thing supervene on their physical properties [Crane]
     Full Idea: It is sometimes said that the aesthetic properties of a thing supervene on its physical properties.
     From: Tim Crane (Elements of Mind [2001], 2.16)
     A reaction: A confusing example, as aesthetic properties only exist if there is an observer. Is 'supervenience' just an empty locution which tries to avoid reduction?
7. Existence / C. Structure of Existence / 5. Supervenience / c. Significance of supervenience
Constitution (as in a statue constituted by its marble) is supervenience without identity [Crane]
     Full Idea: A statue is constituted by the marble that makes it up. It is plausible to say that constitution is not the same as identity - since identity is symmetrical and identity is not - but nonetheless constitution is a supervenience relation.
     From: Tim Crane (Elements of Mind [2001], 2.16)
     A reaction: So what makes it a statue, as opposed to a piece of marble? It may well be an abstraction which only exists relative to observers.
7. Existence / D. Theories of Reality / 1. Ontologies
Existence theories must match experience, possibility, logic and knowledge, and not be self-defeating [Moreland]
     Full Idea: A theory of existence should 1) be consistent with what actually exists, 2) be consistent with what could exist, 3) not make existence impossible (e.g. in space-time), 4) not violate logic, 5) make knowing the theory possible.
     From: J.P. Moreland (Universals [2001], Ch.6)
     A reaction: A nice bit of metaphilosophical analysis. I still doubt whether a theory of existence is possible (something has to be 'given' a priori), but this is a good place to start the attempt.
7. Existence / D. Theories of Reality / 8. Facts / a. Facts
Events are picked out by descriptions, and facts by whole sentences [Crane]
     Full Idea: Events are picked out using descriptions ('The death of Caesar'), while facts are picked out using whole sentences ('Caesar died').
     From: Tim Crane (Causation [1995], 1.4.2)
     A reaction: Useful, and interesting. He mentions that Kim's usage doesn't agree with this. For analysis purposes, this means that an event is a more minimal item than a fact, and many facts will contain events as components.
7. Existence / E. Categories / 2. Categorisation
Infant brains appear to have inbuilt ontological categories [Goldman]
     Full Idea: Infant behaviour implies inbuilt ontological categories of thing, place, event, path, action, sound, manner, amount and number. ...There is an algebra of relationships between them.
     From: Alvin I. Goldman (Phil Applications of Cognitive Science [1993], p.109)
     A reaction: Interesting. We would expect the categories in infant brains to have instrumental value, but we don't have to accept them as true. Adults (even Aristotle) are big infants.
8. Modes of Existence / B. Properties / 7. Emergent Properties
The distinction between 'resultant' properties (weight) and 'emergent' properties is a bit vague [Crane]
     Full Idea: The distinction between 'resultant' properties like weight, and 'emergent' properties like colour, seems intuitive enough, but on examination it is very hard to make precise.
     From: Tim Crane (Elements of Mind [2001], 2.18)
     A reaction: It is no coincidence that the examples are of primary and secondary qualities. If 'the physical entails the mental' then all mental properties are resultant.
If mental properties are emergent they add a new type of causation, and physics is not complete [Crane]
     Full Idea: Whatever the causal process is, it remains true that if emergentism is true, the completeness of physics is false; there are some effects which would not have come about if mental things were absent from the world.
     From: Tim Crane (Elements of Mind [2001], 2.18)
     A reaction: Emergentism looks to me like an incoherent concept, unless it is another word for dualism.
8. Modes of Existence / B. Properties / 13. Tropes / a. Nature of tropes
Tropes are like Hume's 'impressions', conceived as real rather than as ideal [Moreland]
     Full Idea: Tropes are (says Campbell) substances (in Hume's sense), and indeed resemble his impressions conceived realistically rather than idealistically.
     From: J.P. Moreland (Universals [2001], Ch.3)
     A reaction: An interesting link. It doesn't get rid of the problem Hume has, of saying when two impressions are the same. Are they types or tokens? Trope-theory claims they are tokens. Hume's ontology includes 'resemblance'.
8. Modes of Existence / B. Properties / 13. Tropes / b. Critique of tropes
A colour-trope cannot be simple (as required), because it is spread in space, and so it is complex [Moreland]
     Full Idea: A property-instance must be spread out in space, or it is not clear how a colour nature can be present, but then it has to be a complex entity, and tropes are supposed to be simple entities.
     From: J.P. Moreland (Universals [2001], Ch.3)
     A reaction: Seems a fair point. Nothing else in reality can be sharply distinguished, so why should 'simple' and 'complex'?
In 'four colours were used in the decoration', colours appear to be universals, not tropes [Moreland]
     Full Idea: If a decorator says that they used four colours to decorate a house, four tropes is not what was meant, and the statement seems to view colours as universals.
     From: J.P. Moreland (Universals [2001], Ch.3)
     A reaction: Although I am suspicious of using language to deduce ontology, you have to explain why certain statements (like this) are even possible to make.
8. Modes of Existence / C. Powers and Dispositions / 5. Powers and Properties
Properties are causes [Crane]
     Full Idea: Properties are causes.
     From: Tim Crane (Elements of Mind [2001], 2.17)
     A reaction: We can't detect properties if they lack causal powers. This may be a deep confusion. Properties are what make causal powers possible, but that isn't what properties are?
8. Modes of Existence / D. Universals / 1. Universals
If properties are universals, what distinguishes two things which have identical properties? [Moreland]
     Full Idea: If properties are universals, what account can be given of the individuation of two entities that have all their pure properties in common?
     From: J.P. Moreland (Universals [2001], Ch.1)
     A reaction: Is this a big problem? Maybe only a space-time location can do it. Or, in the nice case where the universe is just two identical spheres, it may be impossible.
One realism is one-over-many, which may be the model/copy view, which has the Third Man problem [Moreland]
     Full Idea: One version of realism says that the universal does not enter into the being of its instances, and thus is a One-Over-Many. One version of this is the model/copy view, but this is not widely held, because of difficulties such as the Third Man Argument.
     From: J.P. Moreland (Universals [2001], Ch.1)
     A reaction: This presumably arises if the model is held to have the properties of the copy (self-predication), and looks like a bad theory
Realists see properties as universals, which are single abstract entities which are multiply exemplifiable [Moreland]
     Full Idea: Traditional realism is the view that a property is a universal construed as a multiply exemplifiable abstract entity that is a numerically identical constituent in each of its instances.
     From: J.P. Moreland (Universals [2001], Ch.4)
     A reaction: Put like that, it seems hard to commit oneself fully to realism. How can two red buses contain one abstract object spread out between them. Common sense says there are two 'rednesses' which resemble one another, which is a version of nominalism.
8. Modes of Existence / D. Universals / 2. Need for Universals
Evidence for universals can be found in language, communication, natural laws, classification and ideals [Moreland]
     Full Idea: Those who believe in universals appeal to the meaningfulness of language, the lawlike nature of causation, the inter-subjectivity of thinking, our ability to classify new entities, gradation, and the need for perfect standards or paradigms.
     From: J.P. Moreland (Universals [2001], Ch.1)
     A reaction: Of these, language and communication ought to be explicable by convention, but classification and natural laws look to me like the best evidence.
The traditional problem of universals centres on the "One over Many", which is the unity of natural classes [Moreland]
     Full Idea: Historically the problem of universals has mainly been about the "One over Many", which involves giving an account of the unity of natural classes.
     From: J.P. Moreland (Universals [2001], Ch.1)
     A reaction: This still strikes me as the main problem (rather than issues of language). If universals are not natural, they must be analysed as properties, which break down into causation, which is seen as a human convention.
8. Modes of Existence / D. Universals / 3. Instantiated Universals
The One-In-Many view says universals have abstract existence, but exist in particulars [Moreland]
     Full Idea: Another version of realism says is One-In-Many, where the universal is not another particular, but is literally in the instances. The universal is an abstract entity, in the instances by means of a primitive non-spatiotemporal tie of predication.
     From: J.P. Moreland (Universals [2001], Ch.1)
     A reaction: This sounds like Aristotle (and is Loux's view of properties and relations). If they are abstract, why must they be confined to particulars?
8. Modes of Existence / D. Universals / 4. Uninstantiated Universals
How could 'being even', or 'being a father', or a musical interval, exist naturally in space? [Moreland]
     Full Idea: Many properties (being even) and relations (musical intervals, being a father) are such that it is not clear what it would mean to take them as natural things existing in space.
     From: J.P. Moreland (Universals [2001], Ch.4)
     A reaction: 'Being even' certainly seems to be a property, and it is a struggle to see how it could exist in space, unless it is a set of actual or potential brain states.
Maybe universals are real, if properties themselves have properties, and relate to other properties [Moreland]
     Full Idea: Realism about universals is supported by the phenomenon of abstract reference - that is the fact that properties themselves have properties ('red is a colour'), and stand in relation to other properties ('red is more like orange than like blue').
     From: J.P. Moreland (Universals [2001], Ch.1)
     A reaction: While a property may be an obviously natural feature, properties of properties seem more likely to be the produce of human perception and convention. It is a good argument, though.
A naturalist and realist about universals is forced to say redness can be both moving and stationary [Moreland]
     Full Idea: If a property is held to be at the location of the particular, then if there are two objects having the same property, and one object is stationary and the other is moving, the realist is forced to say that the universal is both moving and at rest.
     From: J.P. Moreland (Universals [2001], Ch.4)
     A reaction: The target of this comment is D.M.Armstrong. The example nicely illustrates the problem of trying to combine science and metaphysics. It pushes you back to Platonism, but that seems wrong too…
There are spatial facts about red particulars, but not about redness itself [Moreland]
     Full Idea: When one attends to something existing in space, one attends to an instance of redness, not to redness itself (which is a colour, which resembles orange). The facts about red itself are not spatial facts, but are traditionally seen as a priori synthetic.
     From: J.P. Moreland (Universals [2001], Ch.4)
     A reaction: This is the fact that properties can themselves have properties (and so on?), which seems to take us further and further from the natural world.
8. Modes of Existence / D. Universals / 6. Platonic Forms / a. Platonic Forms
Redness is independent of red things, can do without them, has its own properties, and has identity [Moreland]
     Full Idea: Four arguments for Platonism: 1) there are truths about redness (it's a colour) even if nothing red exists, 2) redness does not depend on particulars, 3) most universals are at some time not exemplified, 4) universals satisfy the criteria of existence.
     From: J.P. Moreland (Universals [2001], Ch.6)
     A reaction: This adds up to quite a good case, particularly the point that things can be said about redness which are independent of any particular, but the relationships between concepts and the brain seems at the heart of the problem.
8. Modes of Existence / E. Nominalism / 1. Nominalism / a. Nominalism
Moderate nominalism attempts to embrace the existence of properties while avoiding universals [Moreland]
     Full Idea: Moderate nominalism attempts to embrace the existence of properties while avoiding universals.
     From: J.P. Moreland (Universals [2001], Ch.2)
     A reaction: Clearly there is going to be quite a struggle to make sense of 'exists' here (Russell tries 'subsists). Presumably each property must be a particular?
8. Modes of Existence / E. Nominalism / 2. Resemblance Nominalism
Unlike Class Nominalism, Resemblance Nominalism can distinguish natural from unnatural classes [Moreland]
     Full Idea: Resemblance Nominalism is clearly superior to Class Nominalism, since the former offers a clear ground for distinguishing between natural and unnatural classes.
     From: J.P. Moreland (Universals [2001], Ch.2)
     A reaction: Important. It seems evident to me that there are natural classes, and the only ground for this claim would be either the resemblance or the identity of properties.
8. Modes of Existence / E. Nominalism / 3. Predicate Nominalism
There can be predicates with no property, and there are properties with no predicate [Moreland]
     Full Idea: Linguistic predicates are neither sufficient nor necessary for specifying a property. Predicates can be contrived which express no property, properties are far more numerous than linguistic predicates, and properties are what make predicates apply.
     From: J.P. Moreland (Universals [2001], Ch.2)
     A reaction: This seems to me conclusive, and is a crucial argument against anyone who thinks that our metaphysics can simply be inferred from our language.
8. Modes of Existence / E. Nominalism / 5. Class Nominalism
We should abandon the concept of a property since (unlike sets) their identity conditions are unclear [Moreland]
     Full Idea: Some argue that compared to sets, the identity conditions for properties are obscure, and so properties, including realist depictions of them, should be rejected.
     From: J.P. Moreland (Universals [2001], Ch.6)
     A reaction: I have never thought that difficulty in precisely identifying something was a good reason for denying its existence. Consider low morale in a work force. 2nd thoughts: I like this!
9. Objects / B. Unity of Objects / 2. Substance / a. Substance
Traditional substance is separate from properties and capable of independent existence [Crane]
     Full Idea: The traditional concept of substance says substances bear properties which are distinct from them, and substances are capable of independent existence.
     From: Tim Crane (Elements of Mind [2001], 2.9)
     A reaction: Put like that, it sounds ridiculous as a physical theory. It is hard to dislodge substance, though, from a priori human metaphysics.
9. Objects / F. Identity among Objects / 7. Indiscernible Objects
Most philosophers think that the identity of indiscernibles is false [Moreland]
     Full Idea: Most philosophers think that the identity of indiscernibles is false.
     From: J.P. Moreland (Universals [2001], Ch.7)
     A reaction: This is as opposed to the generally accepted 'indiscernibility of identicals'. 'Discernment' is an epistemological concept, and 'identity' is an ontological concept.
11. Knowledge Aims / A. Knowledge / 4. Belief / a. Beliefs
Maybe there are two kinds of belief - 'de re' beliefs and 'de dicto' beliefs [Crane]
     Full Idea: Some philosophers have claimed that there are two kinds of belief, 'de re' belief and 'de dicto' belief.
     From: Tim Crane (Elements of Mind [2001], 4.35)
     A reaction: Interesting, though it may only distinguish two objects of belief, not two types. Internalist and externalist views are implied.
Maybe beliefs don't need to be conscious, if you are not conscious of the beliefs guiding your actions [Crane]
     Full Idea: The beliefs that are currently guiding your actions do not need to be in your stream of consciousness, which suggests that beliefs do not need to be conscious at all.
     From: Tim Crane (Elements of Mind [2001], 4.31)
     A reaction: Too bold, I think. Presumably this would eliminate all the other propositional attitudes from consciousness. There would only be qualia left!
11. Knowledge Aims / A. Knowledge / 6. Knowing How
Many cases of knowing how can be expressed in propositional terms (like how to get somewhere) [Crane]
     Full Idea: There are plenty of cases of knowing how to do something, where that knowledge can also be expressed - without remainder, as it were - in propositional terms (such as knowing how to get to the Albert Hall).
     From: Tim Crane (Elements of Mind [2001], 3.28)
     A reaction: Presumably all knowing how could be expressed propositionally by God.
12. Knowledge Sources / B. Perception / 2. Qualities in Perception / d. Secondary qualities
Phenol-thio-urea tastes bitter to three-quarters of people, but to the rest it is tasteless, so which is it? [Crane]
     Full Idea: Phenol-thio-urea tastes bitter to three-quarters of people, but to the rest it is tasteless. Is it really bitter, or really tasteless?
     From: Tim Crane (Elements of Mind [2001], 5.44)
     A reaction: A nice reinforcement of a classic Greek question. Good support for the primary/secondary distinction. Common sense, really.
12. Knowledge Sources / B. Perception / 3. Representation
Elephants can be correctly identified from as few as three primitive shapes [Goldman]
     Full Idea: An elephant may be fully represented by nine primitive shapes ('geons'), but it may require as few as three geons in appropriate relations to be correctly identified.
     From: Alvin I. Goldman (Phil Applications of Cognitive Science [1993], p.7)
     A reaction: Encouraging the idea of the mind as a maker of maps and models
12. Knowledge Sources / B. Perception / 4. Sense Data / a. Sense-data theory
One can taste that the wine is sour, and one can also taste the sourness of the wine [Crane]
     Full Idea: One can taste that the wine is sour, and one can also taste the sourness of the wine.
     From: Tim Crane (Elements of Mind [2001], 5.42)
     A reaction: …so sense data are optional? We create sense data by objectifying them, but animals just taste the wine, and are direct realists. Tasting the sourness seems to be a case of abstraction.
The traditional supports for the sense datum theory were seeing double and specks before one's eyes [Crane]
     Full Idea: The traditional examples used to support the sense datum theory were seeing double and specks before one's eyes.
     From: Tim Crane (Elements of Mind [2001], 5.43)
     A reaction: Presumably, though, direct realists can move one eye, or having something wrong with a retina.
12. Knowledge Sources / B. Perception / 4. Sense Data / d. Sense-data problems
If we smell something we are aware of the smell separately, but we don't perceive a 'look' when we see [Crane]
     Full Idea: Visual perception seems to differ from some of the other senses; when we become aware of burning toast, we become aware of the smell, ...but we don't see a garden by seeing a 'look' of the garden.
     From: Tim Crane (Elements of Mind [2001], 5.40)
     A reaction: Interesting. Do blind people transfer this more direct perception to a different sense (e.g. the one they rely on most)?
The problems of perception disappear if it is a relation to an intentional state, not to an object or sense datum [Crane]
     Full Idea: The solution to the problem of perception is to deny that it is related to real objects (things or sense-data); rather, perception is an intentional state (with a subject, mode and content), a relation to the intentional content.
     From: Tim Crane (Elements of Mind [2001], 5.42)
     A reaction: Not clear. This definition makes it sound like a propositional attitude.
12. Knowledge Sources / B. Perception / 5. Interpretation
The way in which colour experiences are evoked is physically odd and unpredictable [Goldman]
     Full Idea: A unique yellow experience may be evoked with monochrome light of 580nm, or a mixture of 540nm and 670nm. ..Our interpretation of colour experience is a highly idiosyncratic artefact of our visual system.
     From: Alvin I. Goldman (Phil Applications of Cognitive Science [1993], p.117)
     A reaction: This confirms what I have always thought - that colour (as qualia) is strictly a feature of minds, not of the world.
12. Knowledge Sources / B. Perception / 6. Inference in Perception
If perception is much richer than our powers of description, this suggests that it is non-conceptual [Crane]
     Full Idea: The richness in information of perceptual experience outruns our modes of description of it, which has led some philosophers to claim that the content of perceptual experience is non-conceptual.
     From: Tim Crane (Elements of Mind [2001], 5.45)
     A reaction: It certainly implies that it can't be entirely conceptual, but it still may be that in humans concepts are always involved. Not when I'm waking up in the morning, though.
12. Knowledge Sources / B. Perception / 8. Adverbial Theory
The adverbial theory of perceptions says it is the experiences which have properties, not the objects [Crane]
     Full Idea: The Adverbial Theory of perception holds that the predicates which other theories take as picking out the properties of objects are really adverbs of the perceptual verb; ..instead of strange objects, we just have properties of experiences.
     From: Tim Crane (Elements of Mind [2001], 5.42)
     A reaction: Promising. It fits secondary qualities all right, but what about primary? I 'see bluely', but can I 'see squarely'?
12. Knowledge Sources / D. Empiricism / 2. Associationism
Gestalt psychology proposes inbuilt proximity, similarity, smoothness and closure principles [Goldman]
     Full Idea: Gestalt psychology claims that there are at least four unlearned factors in perceptual grouping - the principles of proximity (close things), of similarity, of good continuation (extending lines in a smooth course), and closure (which completes figures).
     From: Alvin I. Goldman (Phil Applications of Cognitive Science [1993], p.103)
     A reaction: This offers a bridge between Hume's associationism and rationalist claims of innate ideas
13. Knowledge Criteria / A. Justification Problems / 3. Internal or External / a. Pro-internalism
A belief can be justified when the person has forgotten the evidence for it [Goldman]
     Full Idea: A characteristic case in which a belief is justified though the cognizer doesn't know that it's justified is where the original evidence for the belief has long since been forgotten.
     From: Alvin I. Goldman (What is Justified Belief? [1976], II)
     A reaction: This is a central problem for any very literal version of internalism. The fully rationalist view (to which I incline) will be that the cognizer must make a balanced assessment of whether they once had the evidence. Were my teachers any good?
We can't only believe things if we are currently conscious of their justification - there are too many [Goldman]
     Full Idea: Strong internalism says only current conscious states can justify beliefs, but this has the problem of Stored Beliefs, that most of our beliefs are stored in memory, and one's conscious state includes nothing that justifies them.
     From: Alvin I. Goldman (Internalism Exposed [1999], §2)
     A reaction: This point seems obviously correct, but one could still have a 'fairly strong' version, which required that you could always call into consciousness the justificiation for any belief that you happened to remember.
Internalism must cover Forgotten Evidence, which is no longer retrievable from memory [Goldman]
     Full Idea: Even weak internalism has the problem of Forgotten Evidence; the agent once had adequate evidence that she subsequently forgot; at the time of epistemic appraisal, she no longer has adequate evidence that is retrievable from memory.
     From: Alvin I. Goldman (Internalism Exposed [1999], §3)
     A reaction: This is certainly a basic problem for any account of justification. It will rule out any strict requirement that there be actual mental states available to support a belief. Internalism may be pushed to include non-conscious parts of the mind.
Internal justification needs both mental stability and time to compute coherence [Goldman]
     Full Idea: The problem for internalists of Doxastic Decision Interval says internal justification must avoid mental change to preserve the justification status, but must also allow enough time to compute the formal relations between beliefs.
     From: Alvin I. Goldman (Internalism Exposed [1999], §4)
     A reaction: The word 'compute' implies a rather odd model of assessing coherence, which seems instantaneous for most of us where everyday beliefs are concerned. In real mental life this does not strike me as a problem.
13. Knowledge Criteria / A. Justification Problems / 3. Internal or External / b. Pro-externalism
If justified beliefs are well-formed beliefs, then animals and young children have them [Goldman]
     Full Idea: If one shares my view that justified belief is, at least roughly, well-formed belief, surely animals and young children can have justified beliefs.
     From: Alvin I. Goldman (What is Justified Belief? [1976], III)
     A reaction: I take this to be a key hallmark of the externalist view of knowledge. Personally I think we should tell the animals that they have got true beliefs, but that they aren't bright enough to aspire to 'knowledge'. Be grateful for what you've got.
13. Knowledge Criteria / B. Internal Justification / 5. Coherentism / c. Coherentism critique
Coherent justification seems to require retrieving all our beliefs simultaneously [Goldman]
     Full Idea: The problem of Concurrent Retrieval is a problem for internalism, notably coherentism, because an agent could ascertain coherence of her entire corpus only by concurrently retrieving all of her stored beliefs.
     From: Alvin I. Goldman (Internalism Exposed [1999], §3)
     A reaction: Sounds neat, but not very convincing. Goldman is relying on scepticism about short-term memory, but all belief and knowledge will collapse if we go down that road. We couldn't do simple arithmetic if Goldman's point were right.
13. Knowledge Criteria / C. External Justification / 1. External Justification
Is knowledge just a state of mind, or does it also involve the existence of external things? [Crane]
     Full Idea: It is controversial whether knowledge is a state of mind, or a composite state involving a thought about something, plus its existence.
     From: Tim Crane (Elements of Mind [2001], 1.5)
     A reaction: Pinpoints the internalism/externalism problem. Knowledge is a special type of belief (but maybe belief with external links!). Tricky. I vote for internalism.
13. Knowledge Criteria / C. External Justification / 3. Reliabilism / a. Reliable knowledge
Justification depends on the reliability of its cause, where reliable processes tend to produce truth [Goldman]
     Full Idea: The justificational status of a belief is a function of the reliability of the processes that cause it, where (provisionally) reliability consists in the tendency of a process to produce beliefs that are true rather than false.
     From: Alvin I. Goldman (What is Justified Belief? [1976], II)
     A reaction: Goldman's original first statement of reliabilism, now the favourite version of externalism. The obvious immediate problem is when a normally very reliable process goes wrong. Wise people still get it wrong, or right for the wrong reasons.
Reliability involves truth, and truth is external [Goldman]
     Full Idea: Reliability involves truth, and truth (on the usual assumption) is external.
     From: Alvin I. Goldman (Internalism Exposed [1999], §6)
     A reaction: As an argument for externalism this seems bogus. I am not sure that truth is either 'internal' or 'external'. How could the truth of 3+2=5 be external? Facts are mostly external, but I take truth to be a relation between internal and external.
15. Nature of Minds / B. Features of Minds / 1. Consciousness / e. Cause of consciousness
The core of the consciousness problem is the case of Mary, zombies, and the Hard Question [Crane]
     Full Idea: The three arguments that have been used to articulate the problem of consciousness are the knowledge argument ('Mary'), the possibility of 'zombies' (creatures like us but lacking phenomenal consciousness), and the explanatory gap (the Hard Question).
     From: Tim Crane (Elements of Mind [2001], 3.26)
     A reaction: All of these push towards the implausible claim that there could never be a physical explanation of why we experience things. Zombies are impossible, in my opinion.
15. Nature of Minds / B. Features of Minds / 4. Intentionality / a. Nature of intentionality
Intentionalism does not require that all mental states be propositional attitudes [Crane]
     Full Idea: Intentionalism (the doctrine that all mental states are intentional) need not be the thesis that all mental states are propositional attitudes.
     From: Tim Crane (Elements of Mind [2001], 3.22)
     A reaction: This points to the requirement for an intentionalist to prove that so-called 'qualia' states are essentially intentional, which is not implausible.
Object-directed attitudes like love are just as significant as propositional attitudes [Crane]
     Full Idea: Love, hate, and the other object-directed attitudes have as much of a role in explaining behaviour as the propositional attitudes.
     From: Tim Crane (Elements of Mind [2001], 4.34)
     A reaction: A good clarification of the range of intentional states. Objects seem to be external, where propositions are clearly internal.
15. Nature of Minds / B. Features of Minds / 5. Qualia / a. Nature of qualia
If someone removes their glasses the content of experience remains, but the quality changes [Crane]
     Full Idea: There is a phenomenal difference between a short-sighted person wearing glasses and not; they do not judge that the world is different, but the properties of the experience (the qualia) have changed.
     From: Tim Crane (Elements of Mind [2001], 5.43)
     A reaction: Could be challenged. If a notice becomes unreadable, that is more than the qualia changing.
15. Nature of Minds / B. Features of Minds / 5. Qualia / b. Qualia and intentionality
Pains have a region of the body as their intentional content, not some pain object [Crane]
     Full Idea: The intentional object of a pain-state is a part or region of the body, not a pain-object.
     From: Tim Crane (Elements of Mind [2001], 3.24)
     A reaction: Plausible. Has anyone ever suffered from pain without some sense of what part of the body is actually in pain?
15. Nature of Minds / B. Features of Minds / 5. Qualia / c. Explaining qualia
Weak intentionalism says qualia are extra properties; strong intentionalism says they are intentional [Crane]
     Full Idea: Weak intentionalism says all mental states are intentional, but qualia are higher-order properties of these states. ..Strong intentionalists say the phenomenal character of a sensation consists purely in that state's intentionality.
     From: Tim Crane (Elements of Mind [2001], 3.25)
     A reaction: The weak version sounds better. Asking 'how could a thought have a quality of experience just by being about something?' is a restatement of the traditional problem, which won't go away. The Hard Question.
15. Nature of Minds / B. Features of Minds / 6. Inverted Qualia
With inverted qualia a person's experiences would change, but their beliefs remain the same [Crane]
     Full Idea: The right thing to say about inverted qualia is that the person's experiences are different from other people's, but their beliefs are the same.
     From: Tim Crane (Elements of Mind [2001], 5.44)
     A reaction: Right - which reinforces the idea that all beliefs are the result of judgement, and none come directly from perception.
15. Nature of Minds / C. Capacities of Minds / 3. Abstraction by mind
Abstractions are formed by the mind when it concentrates on some, but not all, the features of a thing [Moreland]
     Full Idea: If something is 'abstract' it is got before the mind by an act of abstraction, that is, by concentrating attention on some (but not all) of what is presented.
     From: J.P. Moreland (Universals [2001], Ch.3)
     A reaction: Presumably it usually involves picking out the behavioural or causal features, and leaving out the physical features - though I suppose it works for physical properties too…
16. Persons / C. Self-Awareness / 1. Introspection
Introspection is really retrospection; my pain is justified by a brief causal history [Goldman]
     Full Idea: Introspection should be regarded as a form of retrospection. Thus, a justified belief that I am 'now' in pain gets its justificational status from a relevant, though brief, causal history.
     From: Alvin I. Goldman (What is Justified Belief? [1976], II)
     A reaction: He cites Hobbes and Ryle as having held this view. See Idea 6668. I am unclear why the history must be 'causal'. I may not know the cause of the pain. I may not believe an event which causes a proposition, or I may form a false belief from it.
17. Mind and Body / A. Mind-Body Dualism / 1. Dualism
Descartes did not think of minds as made of a substance, because they are not divisible [Crane]
     Full Idea: It would be wrong to represent Descartes' view as the idea that bodies are made of one kind of stuff and minds of another; he did not think minds are made of stuff at all, because then they would be divisible.
     From: Tim Crane (Elements of Mind [2001], 2.10)
     A reaction: I'm not convinced. It could be an indivisible substance. Without a mental substance, Descartes may have to say the mind is an abstraction, perhaps a pattern of Platonic forms.
17. Mind and Body / A. Mind-Body Dualism / 6. Epiphenomenalism
Functionalism defines mental states by their causal properties, which rules out epiphenomenalism [Crane]
     Full Idea: Functionalism holds that it is in the nature of certain mental states to have certain effects; therefore there can be no mental epiphenomena.
     From: Tim Crane (Elements of Mind [2001], 2.14)
     A reaction: I strongly resist the idea that a thing's identity is its function. Functionalism may not say that. Mind is an abstraction referring to a causal nexus of unknowable components.
17. Mind and Body / D. Property Dualism / 1. Reductionism critique
The problems of misrepresentation and error have dogged physicalist reductions of intentionality [Crane]
     Full Idea: The fundamental problems of misrepresentation and error have dogged physicalist reductions of intentionality.
     From: Tim Crane (Elements of Mind [2001], 3.26)
     A reaction: If footprints or tree-rings are the model for reductions of intentionality, there doesn't seem much scope in them for giving false information, except by some freak event.
17. Mind and Body / D. Property Dualism / 3. Property Dualism
Properties dualism says mental properties are distinct from physical, despite a single underlying substance [Crane]
     Full Idea: According to property dualism, mental properties are distinct from physical properties, even though they are properties of one substance.
     From: Tim Crane (Elements of Mind [2001], 2.10)
     A reaction: Two properties may be phenomenologically different (transparent and magnetic), but that doesn't put them in different ontological categories.
17. Mind and Body / D. Property Dualism / 4. Emergentism
Non-reductive physicalism seeks an explanation of supervenience, but emergentists accept it as basic [Crane]
     Full Idea: While the non-reductive physicalist believes that mental/physical supervenience must be explained, the emergentist is willing to accept it as a fact of nature.
     From: Tim Crane (Elements of Mind [2001], 2.18)
     A reaction: A good reason not to be an emergentist. No philosopher should abandon the principle of sufficient reason.
17. Mind and Body / D. Property Dualism / 5. Supervenience of mind
If mental supervenes on the physical, then every physical cause will be accompanied by a mental one [Crane]
     Full Idea: If the mental supervenes on the physical, then whenever a physical cause brings about some effect, a mental cause comes along for the ride.
     From: Tim Crane (Elements of Mind [2001], 2.17)
     A reaction: This is why supervenience seems to imply epiphenomenalism. The very concept of supervenience is dubious.
17. Mind and Body / E. Mind as Physical / 1. Physical Mind
Identity theory is either of particular events, or of properties, depending on your theory of causation [Crane]
     Full Idea: If causation concerns events, then we have an identity theory of mental and physical events (particulars) [Davidson]. If causation is by properties, then it is mental and physical properties which are identical [Lewis and Armstrong].
     From: Tim Crane (Elements of Mind [2001], 2.14)
     A reaction: Events are tokens, and properties are types. Tricky. Events are dynamic, but properties can be static.
Physicalism may be the source of the mind-body problem, rather than its solution [Crane]
     Full Idea: Physicalism may be the source of the mind-body problem, rather than its solution.
     From: Tim Crane (Elements of Mind [2001], 2.19)
     A reaction: Certainly if the physical is seen as just a pile of atoms, it is hard to see how they could ever think (see idea 1909).
17. Mind and Body / E. Mind as Physical / 5. Causal Argument
Overdetermination occurs if two events cause an effect, when each would have caused it alone [Crane]
     Full Idea: Causal overdetermination is when an effect has more than one cause, and each event would have caused the effect if the other one had not done so.
     From: Tim Crane (Elements of Mind [2001], 2.13)
     A reaction: Overdetermination is a symptom that an explanation is questionable, but it can occur. Two strong people can join to push over a light hatstand.
17. Mind and Body / E. Mind as Physical / 7. Anti-Physicalism / a. Physicalism critique
The completeness of physics must be an essential component of any physicalist view of mind [Crane]
     Full Idea: I claim that the completeness of physics must be an essential component of any physicalist view of mind.
     From: Tim Crane (Elements of Mind [2001], 2.12)
     A reaction: He does not convince me of this. The mind may be within physics, but why should we say a priori that no exceptions to physical law will ever be discovered. Crane is setting up straw men.
17. Mind and Body / E. Mind as Physical / 7. Anti-Physicalism / c. Knowledge argument
Experience teaches us propositions, because we can reason about our phenomenal experience [Crane]
     Full Idea: In experience we learn propositions, since someone can reason using the sentence 'Red looks like this' (e.g. 'If red looks like this, then either it looks like this to dogs or it doesn't').
     From: Tim Crane (Elements of Mind [2001], 3.28)
     A reaction: The fact that we can create propositions about experiences doesn't prove that experience is inherently propositional.
18. Thought / C. Content / 5. Twin Earth
The Twin Earth argument depends on reference being determined by content, which may be false. [Crane]
     Full Idea: The Twin Earth argument does not refute internalism, since it depends on the 'Content-Determines-Reference' principle, which internalists can reject.
     From: Tim Crane (Elements of Mind [2001], 4.37)
     A reaction: The idea is that content should be understood in a context (e.g. on a particular planet). Indexicals count against a totally narrow view of content (Twins thinking 'I am here').
18. Thought / C. Content / 6. Broad Content
Broad content entails the existence of the object of the thought [Crane]
     Full Idea: If a mental state is broad, then the existence of the mental state entails the existence of its object.
     From: Tim Crane (Elements of Mind [2001], 1.7)
     A reaction: Hence thinking of non-existent things like unicorns is problematic for externalists. However, externalists can think about numbers or Platonic ideals.
18. Thought / C. Content / 8. Intension
In intensional contexts, truth depends on how extensions are conceived. [Crane]
     Full Idea: Intensional contexts are those where truth or falsehood depends on the way the extensions are conceived.
     From: Tim Crane (Elements of Mind [2001], 1.4)
     A reaction: An important distinction for anyone defending an internalist view of concepts or of knowledge
18. Thought / D. Concepts / 4. Structure of Concepts / b. Analysis of concepts
It is always open to a philosopher to claim that some entity or other is unanalysable [Moreland]
     Full Idea: It is always open to a philosopher to claim that some entity or other is unanalysable.
     From: J.P. Moreland (Universals [2001], Ch.2)
     A reaction: For example, Davidson on truth. There is an onus to demonstrate why all attempted analyses fail.
26. Natural Theory / C. Causation / 2. Types of cause
Causation can be seen in counterfactual terms, or as increased probability, or as energy flow [Crane]
     Full Idea: A theory of causation might say 'If A had not existed, B would not have existed' (counterfactual theory), or 'B is more likely if A occurs' (probabilistic), or 'energy flows from A to B'.
     From: Tim Crane (Elements of Mind [2001], 2.11)
     A reaction: As always, it is vital to separate epistemology from ontology. Energy won't cover agents. Whisper "Fire!" in a theatre.
26. Natural Theory / C. Causation / 4. Naturalised causation
A cause has its effects in virtue of its properties [Crane]
     Full Idea: Some philosophers say that a cause has its effects in virtue of its properties.
     From: Tim Crane (Causation [1995], 1.4.2)
     A reaction: The trouble with this approach, I think, is that it encourages us to invent dubious properties, because every explanation of an effect will require one. Dormative properties, for example, are ascribed to sleeping pills.
26. Natural Theory / C. Causation / 8. Particular Causation / b. Causal relata
Causes are properties, not events, because properties are what make a difference in a situation [Crane]
     Full Idea: My view is that causes are properties (not events); when we look for causes, we look for the aspect of a situation which made a difference, and aspects are properties or qualities.
     From: Tim Crane (Elements of Mind [2001], 2.14)
     A reaction: He is talking about explanations, which may not be causes, or at least they have a different emphasis. Don't events 'make a difference'? Events are ontologically weird
26. Natural Theory / C. Causation / 9. General Causation / a. Constant conjunction
The regularity theory explains a causal event by other items than the two that are involved [Crane]
     Full Idea: An unsatisfactory aspect of the regularity thesis is that it explains why this A caused this B in terms of facts about things other that this A and this B. But we want to know what it is about this A and this B that makes one the cause of the other?
     From: Tim Crane (Causation [1995], 1.3)
     A reaction: Well said. This is the failing of any attempt to define things by their relationships (e.g. functional definitions). Hume, of course, was only relying on regularity because when he focused on the actual A and B, they had no helpful experiences to offer.
27. Natural Reality / D. Time / 1. Nature of Time / h. Presentism
'Presentism' is the view that only the present moment exists [Moreland]
     Full Idea: 'Presentism' is the view that only the present moment exists.
     From: J.P. Moreland (Universals [2001], Ch.6)
     A reaction: And Greek scepticism doubted even the present, since there is no space between past and future. It is a delightfully vertigo-inducing idea.
28. God / B. Proving God / 2. Proofs of Reason / a. Ontological Proof
It seems that 'exists' could sometimes be a predicate [Crane]
     Full Idea: The view that 'exists' is never a predicate is not plausible.
     From: Tim Crane (Elements of Mind [2001], 1.7)
     A reaction: He doesn't enlarge. Russell says 'exists' is a quantifier. 'Your very existence offends me - I hope it is confiscated'.
