6891 | Quine's naturalistic and empirical view is based entirely on first-order logic and set theory [Quine, by Mautner] |
Full Idea: Quine has aimed at a naturalistic and empirical world-view, and claims that first-order logic and set theory provide a framework sufficient for the articulation of our knowledge of the world. | |
From: report of Willard Quine (Word and Object [1960]) by Thomas Mautner - Penguin Dictionary of Philosophy p.465 | |
A reaction: Consequently he is fairly eliminativist about meaning and mental states, and does without universals in his metaphysics. An impressively puritanical enterprise, taking Ockham's Razor to the limit, but I find it hard to swallow. |
6310 | Enquiry needs a conceptual scheme, so we should retain the best available [Quine] |
Full Idea: No enquiry is possible without some conceptual scheme, so we may as well retain and use the best one we know. | |
From: Willard Quine (Word and Object [1960], §01) | |
A reaction: This remark leads to Davidson's splendid paper 'On the Very Idea of a Conceptual Scheme'. Quine's remark raises the question of how we know which conceptual scheme is 'best'. |
4098 | 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? |
12798 | Plurals can in principle be paraphrased away altogether [Quine] |
Full Idea: By certain standardizations of phrasing the contexts that call for plurals can in principle be paraphrased away altogether. | |
From: Willard Quine (Word and Object [1960], §19) | |
A reaction: Laycock, who quotes this, calls it 'unduly optimistic', but I presume that it was the standard view of plural reference until Boolos raised the subject. |
17905 | Any progression will do nicely for numbers; they can all then be used to measure multiplicity [Quine] |
Full Idea: The condition on an explication of number can be put succinctly: any progression will do nicely. Russell once held that one must also be able to measure multiplicity, but this was a mistake; any progression can be fitted to that further condition. | |
From: Willard Quine (Word and Object [1960], §54) | |
A reaction: [compressed] This is the strongest possible statement that the numbers are the ordinals, and the Peano Axioms will define them. The Fregean view that cardinality comes first is redundant. |
9556 | Nearly all of mathematics has to quantify over abstract objects [Quine] |
Full Idea: Mathematics, except for very trivial portions such as very elementary arithmetic, is irredeemably committed to quantification over abstract objects. | |
From: Willard Quine (Word and Object [1960], §55) | |
A reaction: Personally I would say that we are no more committed to such things than actors in 'The Tempest' are committed to the existence of Prospero and Caliban (which is quite a strong commitment, actually). |
4077 | 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? |
4078 | 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. |
16462 | The quest for ultimate categories is the quest for a simple clear pattern of notation [Quine] |
Full Idea: The quest of a simplest, clearest overall pattern of canonical notation is not to be distinguished from a quest of ultimate categories, a limning of the most general traits of reality. | |
From: Willard Quine (Word and Object [1960], §33) | |
A reaction: I won't disagree, as long as we recognise that reality calls the shots, not the notation, and that even animals must have some sort of system of categories, achieved without 'notation'. |
4083 | 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. |
4082 | 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. |
4079 | 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? |
15723 | Either dispositions rest on structures, or we keep saying 'all things being equal' [Quine] |
Full Idea: The further a disposition is from those that can confidently be pinned on molecular structure or something comparably firm, the more our talk of it tends to depend on a vague factor of 'caeteris paribus' | |
From: Willard Quine (Word and Object [1960], §46) | |
A reaction: I approve of this. It is precisely the point of scientific essentialism, I take it. We are faced with innumerable uncertain dispositions, but once the underlying mechanisms are known, their role in nature becomes fairly precise. |
15490 | Explain unmanifested dispositions as structural similarities to objects which have manifested them [Quine, by Martin,CB] |
Full Idea: Quine claims that an unmanifested disposition is explicable in terms of an object having a structure similar to a structure of an object that has manifested the supposed disposition. | |
From: report of Willard Quine (Word and Object [1960], §46) by C.B. Martin - The Mind in Nature 07.4 | |
A reaction: This is probably the best account available for the firm empiricist who denies modal features in the actual world. In other words, a disposition is the result of an induction, not a conditional statement. |
8504 | Quine aims to deal with properties by the use of eternal open sentences, or classes [Quine, by Devitt] |
Full Idea: Quine is not an 'ostrich', because his strategy for dealing with property sentences is clear enough: all talk of attributes is to be dispensed with in favour of talk of eternal open sentences or talk of classes. | |
From: report of Willard Quine (Word and Object [1960], §43) by Michael Devitt - 'Ostrich Nominalism' or 'Mirage Realism'? p.100 | |
A reaction: [See p.209 'Word and Object'] The proposal seems to be that a property like being-human (a category) would be dealt with by classes, and qualitative properties would be dealt with simply as predicates. I like the split, and the first half, not the second. |
8464 | Physical objects in space-time are just events or processes, no matter how disconnected [Quine] |
Full Idea: Physical objects, conceived four-dimensionally in space-time, are not to be distinguished from events or concrete processes. Each comprises simply the content, however heterogeneous, of a portion of space-time, however disconnected and gerrymandered. | |
From: Willard Quine (Word and Object [1960], §36) | |
A reaction: I very much like the suggestion that objects should be thought of as 'processes', but I dislike the idea that they can be gerrymandered. This is a refusal to cut nature at the joints (Idea 7953), which I find very counterintuitive. |
7924 | The notion of a physical object is by far the most useful one for science [Quine] |
Full Idea: In a contest of sheer systematic utility to science, the notion of physical object still leads the field. | |
From: Willard Quine (Word and Object [1960], §48) | |
A reaction: A delightful circumlocution from someone who seems terrified to assert that there just are objects. Not that I object to Quine's caution. It would be disturbing if his researches had revealed that we could manage without objects. But compare Idea 6124. |
4068 | 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. |
8482 | Mathematicians must be rational but not two-legged, cyclists the opposite. So a mathematical cyclist? [Quine] |
Full Idea: Mathematicians are necessarily rational, and not necessarily two-legged; cyclists are the opposite. But what of an individual who counts among his eccentricities both mathematics and cycling? | |
From: Willard Quine (Word and Object [1960], §41) | |
A reaction: Quine's view is that the necessity (and essence) depends on how this eccentric is described. If he loses a leg, he must give up cycling; if he loses his rationality, he must give up the mathematics. Quine is wrong. |
12136 | Cyclist are not actually essentially two-legged [Brody on Quine] |
Full Idea: Cyclists are not essentially two-legged (a one-legged cyclist exists, but can't cycle any more), and mathematicians are not essentially rational (as they can lose rationality and continue to exist, though unable to do mathematics). | |
From: comment on Willard Quine (Word and Object [1960], §41.5) by Baruch Brody - Identity and Essence 5.1 | |
A reaction: Was Quine thinking of the nominal essence of this person - that 'cyclists' necessarily cylce, and 'mathematicians' necessarily do some maths? It is as bad to confuse 'necessary' with 'essential' as to confuse 'use' with 'mention'. |
17594 | We can paraphrase 'x=y' as a sequence of the form 'if Fx then Fy' [Quine] |
Full Idea: For general terms write 'if Fx then Fy' and vice versa, and 'if Fxz then Fyz'..... The conjunction of all these is coextensive with 'x=y' if any formula constructible from the vocabulary is; and we can adopt that conjunction as our version of identity. | |
From: Willard Quine (Word and Object [1960], §47) | |
A reaction: [first half compressed] The main rival views of equality are this and Wiggins (1980:199). Quine concedes that his account implies a modest version of the identity of indiscernibles. Wiggins says identity statements need a sortal. |
15725 | Normal conditionals have a truth-value gap when the antecedent is false. [Quine] |
Full Idea: In its unquantified form 'If p then q' the indicative conditional is perhaps best represented as suffering a truth-value gap whenever its antecedent is false. | |
From: Willard Quine (Word and Object [1960], §46) | |
A reaction: That is, the clear truth-functional reading of the conditional (favoured by Lewis, his pupil) is unacceptable. Quine favours the Edgington line, that we are only interested in situations where the antecedent might be true. |
15722 | Conditionals are pointless if the truth value of the antecedent is known [Quine] |
Full Idea: The ordinary conditional loses its point when the truth value of its antecedent is known. | |
From: Willard Quine (Word and Object [1960], §46) | |
A reaction: A beautifully simple point that reveals a lot about what conditionals are. |
15719 | We feign belief in counterfactual antecedents, and assess how convincing the consequent is [Quine] |
Full Idea: The subjunctive conditional depends, like indirect quotation and more so, on a dramatic projection: we feign belief in the antececent and see how convincing we then find the consequent. | |
From: Willard Quine (Word and Object [1960], §46) | |
A reaction: This seems accurate. It means that we are only interested in when the antecedent is true, and when it is false is irrelevant. |
15721 | Counterfactuals are plausible when dispositions are involved, as they imply structures [Quine] |
Full Idea: The subjunctive conditional is seen at its most respectable in the disposition terms. ...The reason is that they are conceived as built-in, enduring structural traits. | |
From: Willard Quine (Word and Object [1960], §46) | |
A reaction: Surprisingly, this is very sympathetic to a metaphysical view that seems a long way from Quine, since dispositions seem to invite commitment to modal features of reality. But the structural traits are not, of course, modal, in any way! |
15724 | Counterfactuals have no place in a strict account of science [Quine] |
Full Idea: The subjunctive conditional has no place in an austere canonical notation for science - but that ban is less restrictive than would at first appear. | |
From: Willard Quine (Word and Object [1960], §46) | |
A reaction: Idea 15723 shows what he has in mind - that what science aims for is accounts of dispositional mechanisms, which then leave talk of other possible worlds (in Lewis style) as unnecessary. I may be with Quine one this one. |
15720 | What stays the same in assessing a counterfactual antecedent depends on context [Quine] |
Full Idea: The traits to suppose preserved in a counterfactual depend on sympathy for the fabulist's purpose. Compare 'If Caesar were in command, he would use the atom bomb', and 'If Caesar were in command, he would use catapults'. | |
From: Willard Quine (Word and Object [1960], §46) | |
A reaction: This seems to be an important example for the Lewis approach, since you are asked to consider the 'nearest' possible world, but that will depend on context. |
4096 | 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! |
4097 | 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. |
4093 | 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. |
4108 | 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. |
4105 | 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. |
4104 | 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. |
4101 | 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)? |
4102 | 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. |
4109 | 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. |
4103 | 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'? |
4065 | 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. |
4630 | Two theories can be internally consistent and match all the facts, yet be inconsistent with one another [Quine, by Baggini /Fosl] |
Full Idea: Duhem and Quine have maintained that it may be possible to develop two or more theories that are 1) internally consistent, 2) inconsistent with one another, and 3) perfectly consistent with all the data we can muster. | |
From: report of Willard Quine (Word and Object [1960]) by J Baggini / PS Fosl - The Philosopher's Toolkit §1.06 | |
A reaction: Obviously this may be a contingent truth about our theories, but why not presume that this is because we are unable to collect the crucial data (e.g. about prehistoric biology), rather than denigrate the whole concept of a theory, and undermine science? |
4092 | 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. |
4087 | 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. |
4095 | 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. |
4106 | 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. |
4089 | 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? |
4090 | 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. |
4107 | 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. |
4069 | 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. |
4074 | 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. |
4091 | 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. |
4070 | 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. |
4084 | 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. |
4080 | 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. |
4085 | 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). |
4075 | 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. |
3131 | Quine expresses the instrumental version of eliminativism [Quine, by Rey] |
Full Idea: Quine expresses the instrumental version of eliminativism. | |
From: report of Willard Quine (Word and Object [1960]) by Georges Rey - Contemporary Philosophy of Mind Int.3 |
4073 | 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. |
4072 | 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. |
4094 | 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. |
4100 | 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'). |
4067 | 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. |
4063 | 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 |
3988 | Indeterminacy of translation also implies indeterminacy in interpreting people's mental states [Dennett on Quine] |
Full Idea: Quine's thesis of the indeterminacy of radical translation carries all the way in, as the thesis of the indeterminacy of radical interpretation of mental states and processes. | |
From: comment on Willard Quine (Word and Object [1960]) by Daniel C. Dennett - Daniel Dennett on himself p.239 | |
A reaction: Strong scepticism seems wrong here. Davidson's account of charity in interpretation, and the role of truth, seems closer. |
6311 | The firmer the links between sentences and stimuli, the less translations can diverge [Quine] |
Full Idea: The firmer the direct links of a sentence with non-verbal stimulation, the less drastically its translations can diverge from one another from manual to manual. | |
From: Willard Quine (Word and Object [1960], §07) | |
A reaction: This implies (plausibly) that talk about farming will have fairly determinate translations into foreign languages, but talk of philosophy will not. An interesting case is logic, where we might expect tight translation with little non-verbal stimulation. |
6312 | We can never precisely pin down how to translate the native word 'Gavagai' [Quine] |
Full Idea: There is no evident criterion whereby to strip extraneous effects away and leave just the meaning of 'Gavagai' properly so-called - whatever meaning properly so-called may be. | |
From: Willard Quine (Word and Object [1960], §09) | |
A reaction: Quine's famous assertion that translation is ultimately 'indeterminate'. Huge doubts about meaning and language and truth follow from his claim. Personally I think it is rubbish. People become fluent in very foreign languages, and don't have breakdowns. |
6313 | Stimulus synonymy of 'Gavagai' and 'Rabbit' does not even guarantee they are coextensive [Quine] |
Full Idea: Stimulus synonymy of the occasion sentences 'Gavagai' and 'Rabbit' does not even guarantee that 'gavagai' and 'rabbit' are coextensive terms, terms true of the same things. | |
From: Willard Quine (Word and Object [1960], §12) | |
A reaction: Since this scepticism eventually seems to result in the reader no longer knowing what they mean themselves by the word 'rabbit', I doubt Quine's claim. Problems after hearing one word of a foreign language disappear after years of residence. |
6317 | Dispositions to speech behaviour, and actual speech, are never enough to fix any one translation [Quine] |
Full Idea: Rival systems of analytical hypotheses can fit the totality of speech behaviour to perfection, and can fit the totality of dispositions to speech behaviour as well, and still specify mutually incompatible translations of countless sentences. | |
From: Willard Quine (Word and Object [1960], §15) | |
A reaction: This is Quine's final assertion of indeterminacy, having explored charity, bilingual speakers etc. It seems to me that he is a victim of his underlying anti-realism, which won't allow nature to dictate ways of cutting up the world. |
6314 | Weird translations are always possible, but they improve if we impose our own logic on them [Quine] |
Full Idea: Wanton translation can make natives sound as queer as one pleases; better translation imposes our logic upon them. | |
From: Willard Quine (Word and Object [1960], §13) | |
A reaction: This begins to point towards the principle of charity, on which Davidson is so keen, and even on doubts whether two different conceptual schemes are possible. Personally I think there is only one logic (deep down), and the natives will have it. |
6315 | We should be suspicious of a translation which implies that a people have very strange beliefs [Quine] |
Full Idea: The more absurd or exotic the beliefs imputed to a people, the more suspicious we are entitled to be of the translations. | |
From: Willard Quine (Word and Object [1960], §15) | |
A reaction: Quine is famous for his relativist and indeterminate account of translation, but he gradually works his way towards the common sense which Davidson later brought out into the open. |
7903 | The six perfections are giving, morality, patience, vigour, meditation, and wisdom [Nagarjuna] |
Full Idea: The six perfections are of giving, morality, patience, vigour, meditation, and wisdom. | |
From: Nagarjuna (Mahaprajnaparamitashastra [c.120], 88) | |
A reaction: What is 'morality', if giving is not part of it? I like patience and vigour being two of the virtues, which immediately implies an Aristotelian mean (which is always what is 'appropriate'). |
4071 | 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. |
4076 | 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 |
4066 | 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'. |
