| 3137 | Varieties of singular terms are used to designate token particulars [Rey] |
| Full Idea: We designate token particulars with singular terms, such as: proper names, numerals, definite descriptions, demonstratives, pronouns or variables. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 1.1.1) |
| 17447 | Parsons says counting is tagging as first, second, third..., and converting the last to a cardinal [Parsons,C, by Heck] |
| Full Idea: In Parsons's demonstrative model of counting, '1' means the first, and counting says 'the first, the second, the third', where one is supposed to 'tag' each object exactly once, and report how many by converting the last ordinal into a cardinal. | |
| From: report of Charles Parsons (Frege's Theory of Numbers [1965]) by Richard G. Heck - Cardinality, Counting and Equinumerosity 3 | |
| A reaction: This sounds good. Counting seems to rely on that fact that numbers can be both ordinals and cardinals. You don't 'convert' at the end, though, because all the way you mean 'this cardinality in this order'. |
| 3143 | Physics requires the existence of properties, and also the abstract objects of arithmetic [Rey] |
| Full Idea: Physics is committed to arithmetic, which seems committed to abstract objects such as numbers, and its causal explanations seem to appeal to properties, such as mass and charge. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 2.3) |
| 3145 | The Indiscernibility of Identicals is a truism; but the Identity of Indiscernibles depends on possible identical worlds [Rey] |
| Full Idea: Leibniz's Law, the indiscernibility of identicals, is a truism which should not be confused with the more controversial identity of indiscernibles, which depends on the possibility of perfectly replicated universes. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 2.4) |
| 23308 | Reasoning relates to understanding as time does to eternity [Boethius, by Sorabji] |
| Full Idea: Boethius says that reasoning [ratiocinatio] is related to intellectual understanding [intellectus] as time to eternity, involving as it does movement from one stage to another. | |
| From: report of Boethius (The Consolations of Philosophy [c.520], 4, prose 6) by Richard Sorabji - Rationality 'Shifting' | |
| A reaction: This gives true understanding a quasi-religious aura, as befits a subject which is truly consoling. |
| 3172 | Empiricism says experience is both origin and justification of all knowledge [Rey] |
| Full Idea: Two of the key claims of empiricism are that all knowledge must be justified on the basis of experience, and that all knowledge in fact originates in experience. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 4.3) |
| 3166 | Animal learning is separate from their behaviour [Rey] |
| Full Idea: Rats and monkeys exhibit 'latent learning' (learning just for fun) which is later beneficial. They learn with no consequences, and then can't learn when the good consequences are available. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 4.1.1) | |
| A reaction: This looks like a bit of a setback for naturalised epistemology and cognitive science, if learning can't be brought within a stimulus-response framework. |
| 3232 | Abduction could have true data and a false conclusion, and may include data not originally mentioned [Rey] |
| Full Idea: Abduction moves from some data to a 'best explanation'. It is not deduction because the data could be true but the conclusion false, and it is not induction because the conclusion may involve data not mentioned in the premises. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], p.322) |
| 3128 | It's not at all clear that explanation needs to stop anywhere [Rey] |
| Full Idea: It's not at all clear that explanation needs to stop anywhere. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], Int.2) |
| 3136 | The three theories are reduction, dualism, eliminativism [Rey] |
| Full Idea: There are three main views regarding the ontology of mental phenomena: reductionism, dualism and eliminativism. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 1.1) | |
| A reaction: It is precisely this picture which is rejected by Davidson and co, who want something called 'property dualism', with a unique relationship which is labelled 'supervenient'. Unfortunately there is no analogy for it. Not even beauty and a statue. |
| 3141 | Is consciousness 40Hz oscillations in layers 5 and 6 of the visual cortex? [Rey] |
| Full Idea: Crick and Koch claim that visual consciousness is correlated with a 40Hz oscillation in layers five and six of the primary visual cortex. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 2.1) | |
| A reaction: Not many people seem to have been enthused by their proposal. The target is the NCC (Neural Correlate of Consciousness), but we would only accept that location if the 'oscillations' seemed in some way special. |
| 3148 | Dualist privacy is seen as too deep for even telepathy to reach [Rey] |
| Full Idea: The privacy that is a serious issue for the dualist is a peculiarly epistemic privacy that not even telepathy or brain fusions would seem to overcome. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 2.5.4) | |
| A reaction: This is a key idea in the traditional defence of dualism. I'm inclined to think that we are faced with deep privacy not because the mind is so hidden, but because the observer is trapped in NOT being the thing observed. In that sense, rocks are private. |
| 3164 | Intentional explanations are always circular [Rey] |
| Full Idea: There can seem to be no escape from the "intentional circle" - the use of one intentional idiom always seems to presuppose the use of another. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 3.3) | |
| A reaction: The best explanation of this is Conceptual Dualism (Papineau: Thinking about Consciousness). We are locked into dualist concepts because of our long-term ignorance about the brain. |
| 3138 | Arithmetic and unconscious attitudes have no qualia [Rey] |
| Full Idea: The contents of thoughts, beliefs and desires seem quite distinct from qualia. Arithmetic has no particular feeling attached to it, and Freud showed that many propositional attitudes have no feeling at all, as they are unconscious. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 1.1.2) | |
| A reaction: I don't think we should rule out 'pre-conscious' qualia. The fact that advanced human mental capacities like arithmetic have thinned out their qualia doesn't count against qualia being essential to normal mental life. |
| 3142 | Why qualia, and why this particular quale? [Rey] |
| Full Idea: If we allow as a brute fact that certain mental states possess conscious qualitative content, there is still the problem of explaining why they possess one content rather than another (why does this stimulus look RED?). | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 2.1) | |
| A reaction: This strikes me as the Really Hard Question. The Hard Question is merely 'why are creatures aware of their thoughts?' Personally I don't rule out finding a physical answer to the RHQ, and it is certainly not grounds for drifting into neo-dualism. |
| 3224 | If qualia have no function, their attachment to thoughts is accidental [Rey] |
| Full Idea: If qualia are non-functionally defined objects, then their attachment to their role in my thought would seem to be metaphysically accidental. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 11.4.2) | |
| A reaction: A rock at sea can cause a shipwreck without being defined as 'a shipwrecker'. It is, of course, tautological that if qualia have a 'role' in my thoughts, they must have causal powers, but 'function' is a much trickier concept. |
| 3227 | Are qualia a type of propositional attitude? [Rey] |
| Full Idea: Qualitative experience is just a particular species of propositional attitude. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 11.6.1) | |
| A reaction: This sounds very implausible. If I hear a loud and baffling noise, is a proposition instantly involved? When a subtle change of colour occurs in the sky at sunset, is that 'propositional'? Do slugs formulate propositions when they taste garlic? |
| 3226 | Are qualia irrelevant to explaining the mind? [Rey] |
| Full Idea: Phenomenal objects and properties are no more needed to explain the workings of our mind than are angels needed to explain the motion of the planets. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 11.6.1) | |
| A reaction: The question would be whether 'phenomenal properties' contained unique information, which could therefore influence behaviour. It is also a matter of exactly what you are trying to explain. |
| 3229 | If colour fits a cone mapping hue, brightness and saturation, rotating the cone could give spectrum inversion [Rey] |
| Full Idea: If colour can be modelled as a cone, with points mapped by hue, brightness and saturation, then a rotation could be isomorphic with the hues switched, so we may all experience different hues. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 11.7.1) | |
| A reaction: from Levine |
| 3223 | Self-consciousness may just be nested intentionality [Rey] |
| Full Idea: It is tempting to think that if a system has concepts for nested intentionality and first-person reflection, it has all that's needed for self-consciousness. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 11.2.2) | |
| A reaction: If there nothing more than nested intentionality in complex minds like ours, the top level of the nesting would still have a special status. And if the top level always seemed to stay the same while the lower levels changed, I'd probably call it the Self |
| 3162 | Experiments prove that people are often unaware of their motives [Rey] |
| Full Idea: Experiments have shown (Nisbett and Wilson 1977) that people's introspective knowledge is a lot less reliable than they suppose. People are sensitive to but entirely unaware of many factors that influence their social behaviour. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 3.2.2) | |
| A reaction: This type of observation rests on an overemphasis on the conscious mind. We are not conscious of liver events, or of deep buried brain events, both of which motivate us. We should only expect introspection to reveal what is fully conscious. |
| 3163 | Brain damage makes the unreliability of introspection obvious [Rey] |
| Full Idea: The most dramatic phenomena undermining the absolute reliability of introspection are those of blindsight and "anosognosia" (unawareness of one's own brain damage). | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 3.2.2) | |
| A reaction: It might depend on what you expected introspection to reveal. If you only expected it to tell you about your consciousness, it would be unreasonable to expect knowledge of blindsight information by introspection. |
| 5771 | Knowledge of present events doesn't make them necessary, so future events are no different [Boethius] |
| Full Idea: Just as the knowledge of present things imposes no necessity on what is happening, so foreknowledge imposes no necessity on what is going to happen. | |
| From: Boethius (The Consolations of Philosophy [c.520], V.IV) | |
| A reaction: This, I think, is the key idea if you are looking for a theological answer to the theological problem of free will. Don't think of God as seeing the future 'now'. God is outside time, and so only observes all of history just as we observe the present. |
| 5767 | Rational natures require free will, in order to have power of judgement [Boethius] |
| Full Idea: There is freedom of the will, for it would be impossible for any rational nature to exist without it. Whatever by nature has the use of reason has the power of judgement to decide each matter. | |
| From: Boethius (The Consolations of Philosophy [c.520], V.II) | |
| A reaction: A view taken up by Aquinas (Idea 1849) and Kant (Idea 3740). The 'power of judgement' pinpoints the core of rationality, and it is not clear how a robot could fulfil such a power, if it lacked consciousness. Does a machine 'judge' barcodes? |
| 3195 | If reason could be explained in computational terms, there would be no need for the concept of 'free will' [Rey] |
| Full Idea: If a computational account of reasoning processes could be given, then there is no need to settle the issue of "free will", as reason could get along without it. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 8.6) |
| 3196 | Free will isn't evidence against a theory of thought if there is no evidence for free will [Rey] |
| Full Idea: We don't need arguments to show that if there were free will then computational accounts of the mind would be inadequate; what is needed is good evidence that there actually exists such free will in the first place. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 8.6) |
| 5769 | Does foreknowledge cause necessity, or necessity cause foreknowledge? [Boethius] |
| Full Idea: Does foreknowledge of the future cause the necessity of events, or necessity cause the foreknowledge? | |
| From: Boethius (The Consolations of Philosophy [c.520], V.III) | |
| A reaction: An intriguing question, though not one that bothers me. I don't understand how foreknowledge causes necessity, unless God's vision of the future is a kind of 'freezing ray'. Even the gods must bow to necessity (Idea 3016). |
| 5768 | God's universal foreknowledge seems opposed to free will [Boethius] |
| Full Idea: God's universal foreknowledge and freedom of the will seem clean contrary and opposite. | |
| From: Boethius (The Consolations of Philosophy [c.520], V.III) | |
| A reaction: The original source of the great theological and philosophical anguish over free will. The problem is anything which fixes future facts, be it oracular knowledge or scientific prediction. Personally I think free will was an invention by religions. |
| 3180 | Maybe behaviourists should define mental states as a group [Rey] |
| Full Idea: Defining most mental states seems to requiring citing other mental states - but perhaps behaviourists can define them all simultaneously | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 5.3) | |
| A reaction: This is an interesting strategy for trying to avoid the well known circularity of attempting to define mental states in behavioural terms. Behaviourism won't go away. |
| 3165 | Behaviourism is eliminative, or reductionist, or methodological [Rey] |
| Full Idea: There are three different views concerning behaviourism - the 'radical' view, which aims at eliminativism, the 'analytical' view, which is a reductionist enterprise, and the 'methodological' view, somewhere between the two. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 4) | |
| A reaction: The first appears to be ontological, the second about relationships between areas of our language, and the third epistemological. You could attempt language reduction because we can only know behaviour, because that's all there is. |
| 3167 | Animals don't just respond to stimuli, they experiment [Rey] |
| Full Idea: Animals exhibit 'spontaneous alteration' in their behaviour (e.g. varying the route to the food), or improvisation (finding short cuts instead of following training). They use mental maps, or dead reckoning, not just conditioned responses. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 4.1.4) | |
| A reaction: If we can't even get a decent behaviourist account of animal behaviour, presumably the chances for humans look even less good. 'Black box' behaviourism, rather than the eliminativist version, might allow internal mechanisms to modify responses. |
| 3173 | How are stimuli and responses 'similar'? [Rey] |
| Full Idea: Radical behaviourists say animals emit "similar" responses to "similar" reinforcements, but that is empty without specifying in what respect there is a similarity. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 4.3) | |
| A reaction: The point is that when you try to specify the similarity you are (supposedly) forced to use mental language to make the distinctions, thus contradicting behaviourism. It is not, though, self-evidently impossible to give a behaviourist specification. |
| 3179 | Behaviour is too contingent and irrelevant to be the mind [Rey] |
| Full Idea: The two main anti-behaviourist intuitions are that mind and behaviour only relate contingently, and that for much mental life (thinking, emotion) the resulting behaviour seems unimportant. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 5.3) | |
| A reaction: Attractive intuitions, but not unquestionable. Since no two states of mind are ever fully identical, we can never test whether the resulting behaviour arises contingently or necessarily. The second point underestimates the physicality of mental life. |
| 3127 | Dualism and physicalism explain nothing, and don't suggest any research [Rey] |
| Full Idea: Neither dualism nor physicalism provides much serious explanation of any mental phenomena, or even much in the way of a program of research. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], Int.2) | |
| A reaction: I'm not sure if people who demand an "explanation of mental phenomena" are quite clear about what it is they want. God might just say "Mental phenomena are just brain events from the brain's point of view". |
| 3186 | If a normal person lacked a brain, would you say they had no mind? [Rey] |
| Full Idea: If many otherwise ordinary people turned out to have skulls which were empty or filled with oatmeal, would that mean that they didn't have minds? | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 7.1.4) | |
| A reaction: That's a John Locke sort of question, implying that 'persons' are logically independent of their implementation. Personally I would search for a radio receiver, because oatmeal is implausible as a thinker. |
| 3188 | Homuncular functionalism (e.g. Freud) could be based on simpler mechanical processes [Rey] |
| Full Idea: So-called 'homuncular functionalism' (such as Freud's or Plato's internal struggles of the soul) needn't lead to an infinite regress if eventually the homunculi become so stupid they could be replaced by a machine. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 7.2.2) | |
| A reaction: from Fodor |
| 3216 | Is the room functionally the same as a Chinese speaker? [Rey] |
| Full Idea: The question for a computational-representation theory about the Chinese Room is: is what is happening inside the room functionally equivalent to what is happening inside a normal Chinese speaker? | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 10.2.1) | |
| A reaction: Certainly the Room lacks morality ('how can I torture my sister?'). It won't spot connections between recent questions. It won't ask itself questions. It will take years to spot absurd questions. |
| 3220 | Searle is guilty of the fallacy of division - attributing a property of the whole to a part [Rey] |
| Full Idea: You should no more attribute understanding of Chinese to this one part of the system than you should ascribe the properties of the entire British Empire to Queen Victoria. This is the fallacy of division. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 10.2.3) | |
| A reaction: This very nicely pinpoints what is wrong with the Chinese Room argument (nice analogy, too). If you carefully introspect what is involved when you 'understand' something, it is immensely complex, though it feels instant and simple. |
| 3206 | One computer program could either play chess or fight a war [Rey] |
| Full Idea: It is always possible to provide incompatible interpretations of formal theories, so that a computer could use the same program one day to play chess, the next to fight a war. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 9.1.3) | |
| A reaction: This seems to present a huge gulf between human chess players (who 'understand' what they are doing) and machines, but I don't accept it. Giving the machine cameras and multi-level software would fix it. |
| 3140 | If you explain water as H2O, you have reduced water, but not eliminated it [Rey] |
| Full Idea: Reduction is not the same as elimination; if chemists reduce water to H2O, or biologists reduce life to a complex chemical process, they have not shown that they don't exist. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 1.2.1) | |
| A reaction: Depends what you mean by 'elimination'. It is important to be clear whether you are eliminating something from life, or from strict philosophical ontology. Ontologists never mention mountains. |
| 3134 | Human behaviour can show law-like regularity, which eliminativism can't explain [Rey] |
| Full Idea: There is clear evidence against eliminative materialism in the law-like correlations found among millions of answers in standardised school tests, for which it can give no explanation. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], Int.3) | |
| A reaction: Not very persuasive. If neural networks got involved in complex competitions with one another, you would expect them to evolve similar tactics. |
| 3200 | Pattern recognition is puzzling for computation, but makes sense for connectionism [Rey] |
| Full Idea: Connectionism is a way of capturing the holism of pattern recognition, as stressed by many critics of computational theories of mind. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 8.8) | |
| A reaction: I am drawn to the idea that arithmetic derives from pattern recognition, and the latter is basic to all minds (a kind of instant unthinking induction), so this seems to me a win for connectionism. |
| 3201 | Connectionism explains well speed of perception and 'graceful degradation' [Rey] |
| Full Idea: Connectionism is better than other AI strategies at capturing the extraordinary swiftness of perception, and of degrading in a 'graceful' way. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 8.8) | |
| A reaction: A good theory had better capture the extraordinary swiftness of perception. Also the swiftness of recognition. Compare seeing a surprising old friend in a crowd, and recognising the person you are looking for. |
| 3202 | Connectionism explains irrationality (such as the Gamblers' Fallacy) quite well [Rey] |
| Full Idea: Connectionism offers promising accounts of irrational behaviour, such as people's bias towards positive instances, and their tendency to fall for the gamblers' fallacy. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 8.8) | |
| A reaction: That is strong support, because the chances of a computational robot having such tendencies is virtually nil, but all humans have the biases referred to (even philosophers). |
| 3199 | Connectionism assigns numbers to nodes and branches, and plots the outcomes [Rey] |
| Full Idea: In connectionism, each node is given an activation level, and each branch a weight, according to possible degree of effect. This results in 'excitatory' and 'inhibitory' connections. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 8.8) | |
| A reaction: Whether such a system could ever be 'conscious' is not the only interesting question. What could such a system do? Could it ever be good at philosophy? |
| 3150 | Can identity explain reason, free will, non-extension, intentionality, subjectivity, experience? [Rey] |
| Full Idea: Eight properties of mind are problems for the identity theory: rationality, free will, spatiality, privacy, intentionality, essential mentality, subjective content, and the explanatory gap. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 2.7) | |
| A reaction: The list could go on: poetry, creativity, love, normativity... Actually, these are problems for every theory. |
| 3129 | Physicalism offers something called "complexity" instead of mental substance [Rey] |
| Full Idea: In physicalism the "ghost in the machine" is merely replaced by the "complexity" in it. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], Int.2) | |
| A reaction: This is nonsense. No one thinks that mere complexity generates consciousness. The assumption is that we would begin to understand the mind only if we could somehow map the connections of the brain. |
| 3139 | Some attitudes are information (belief), others motivate (hatred) [Rey] |
| Full Idea: Propositional attitudes divide into two broad types: neutral informational ones (belief, suspicion, imagining), and directional ones which motivate an agent (preference, desire, hate). | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 1.1.2) | |
| A reaction: Since suspicions are motivating, and preferences are informational, this is not a very sharp distinction. An alternative would be to say that there is one type, and sometimes the will gets involved. |
| 3171 | Children speak 90% good grammar [Rey] |
| Full Idea: Ninety percent of most young children's utterances are grammatical. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 4.2.4) | |
| A reaction: This is good evidence for some sort of innate element in the grammar of language. But the accurate grammar is not in a particular language. Good communication must be the driving force in all this. |
| 3174 | Good grammar can't come simply from stimuli [Rey] |
| Full Idea: Grammatical sensitivity is in no way a physical property of the stimulus, and we can't imagine how to build a device which would produce grammatical structures in response to the environment. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 4.3) | |
| A reaction: You could try to program it with a set of (say) Aristotelian categories, and mechanisms to sort the environment accordingly. It then has to query its database, in response to practical needs. A doddle. |
| 3213 | Animals may also use a language of thought [Rey] |
| Full Idea: The language of thought need not only be confined to creatures which speak a natural language. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 10.1.1) | |
| A reaction: I take it as axiomatic that our brains are no different in principles and fundamental mechanics from the lowliest of creatures. See Idea 7509. |
| 3170 | We train children in truth, not in grammar [Rey] |
| Full Idea: Very young children have been shown (Brown and Halon 1970) to be 'reinforced' not for their grammar but for the informational content of what they say. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 4.2.1) | |
| A reaction: This is what you would expect. It doesn't follow that the grammar comes from innate mechanisms, because the pressure to get the information right could impose increasing accuracy in grammar. |
| 3215 | Images can't replace computation, as they need it [Rey] |
| Full Idea: Processing of images and mental models seems to require, and therefore is unlikely to replace, computation and representation. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 10.1.2) | |
| A reaction: A good point. If you are a fan of mental imagery, you still have to explain how we can hold an image, or recall it, or manipulate it. I always, I don't know why, wince at the thought of 'computations' among neurons. |
| 3194 | CRTT is good on deduction, but not so hot on induction, abduction and practical reason [Rey] |
| Full Idea: The computational/representational theory of thought has given a good account of deduction, but mechanical theories of induction, abduction and practical reason are needed in order to make a machine which could reason. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 8.5) | |
| A reaction: This is the best analysis of rationality that I have found (four components: deduction, induction, abduction, practical reason). I can think of nothing to add, and certainly none of these should be omitted. |
| 3147 | Problem-solving clearly involves manipulating images [Rey] |
| Full Idea: Recent experiments (Shepard 1982) suggest people have imagistic representations they inspect when solving problems. In comparing two rotated images, the time for comparison varies with the angle of rotation. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 2.5.3) | |
| A reaction: This doesn't prove that they are slowly rotating something. It may just be harder to make the leap to the new shape, when it is 'further away'. Picturing a 20-sided figure, we don't add sides one-by-one. |
| 3175 | Animals map things over time as well as over space [Rey] |
| Full Idea: To map things like food over time, animals must somehow represent events as having temporal properties, and somehow store those representations ready for later use. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 4.3) | |
| A reaction: If the mechanisms for doing this are basic, then so is the ontology. Objects must be categorised, properties spotted, time-spans correlated etc. 'Represent' needs to be sharp to be useful. |
| 3207 | Simple externalism is that the meaning just is the object [Rey] |
| Full Idea: The oldest version of the externalist theory of meaning is the Fido/Fido theory, according to which the meaning of a representation is the object for which it stands. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 9.2) | |
| A reaction: Modern baptismal theories of reference seem to have taken us back to this, for distinct individuals such as Aristotle, or natural kinds like gold. What, though, does 'Fido' mean to me? Asthma! |
| 3176 | Anything bears a family resemblance to a game, but obviously not anything counts as one [Rey] |
| Full Idea: Anything bears a family resemblance to a game, but obviously not anything counts as one. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 4.3) |
| 3181 | A one hour gap in time might be indirectly verified, but then almost anything could be [Rey] |
| Full Idea: You couldn't directly verify that the whole universe had stopped for one hour, but you might indirectly verify it (by prediction) - but then almost anything could be very indirectly verified. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 5.4) | |
| A reaction: Does indirect verification include time travel? Or perfect knowledge of quantum theory, and total knowledge of quantum states. Laplace's Hypothesis. |
| 3204 | The meaning of "and" may be its use, but not of "animal" [Rey] |
| Full Idea: The view that the meaning of language of thought expressions is based on their conceptual role (derived from Wittgenstein's idea of meaning as use), is most plausible for the logical connectives like "and", but implausible for, say, "animal". | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 9.1.2) | |
| A reaction: It was the logical connectives that got LW started on this track. If it doesn't work for 'animal' then does that mean we need two different theories? |
| 3205 | Semantic holism means new evidence for a belief changes the belief, and we can't agree on concepts [Rey] |
| Full Idea: Semantic holism is a desperate measure. Belief content would be continually changed by new beliefs, evidence for a belief would change the target belief, and no two people would ever agree on concepts. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 9.1.2) | |
| A reaction: It is far more plausible to say language is a bit on the holistic side. Total holism is mad. |
| 3209 | Causal theories of reference (by 'dubbing') don't eliminate meanings in the heads of dubbers [Rey] |
| Full Idea: Causal histories may have some role to play in a theory of reference, but the chain of causation requires internal characterisations at each stage, and the original dubber had one thing rather than another in mind when dubbing. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 9.2.1) | |
| A reaction: The modern view of direct reference seems to prefer social context rather than a complete causal chain. |
| 3210 | If meaning and reference are based on causation, then virtually everything has meaning [Rey] |
| Full Idea: What is special about meaning? If meaning and reference are just the result of causal chains, almost everything will mean something, since almost everything is reliably caused by something. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 9.2.2) | |
| A reaction: It would be insane to think that all causal events produced meanings. It is probably better not to mention causation at all when discussing meaning. |
| 3149 | Referential Opacity says truth is lost when you substitute one referring term ('mother') for another ('Jocasta') [Rey] |
| Full Idea: Referential Opacity says you cannot preserve truth if you substitute one referring term for another ('Oedipus desires Jocasta', 'Oedipus desires his mother'). | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 2.5.6) | |
| A reaction: ….That is, in the context of expressing a propositional attitude. 'Oedipus desired his mother' was true. This idea requires some ignorance on the part of the person expressing the thought. |
| 3169 | A simple chaining device can't build sentences containing 'either..or', or 'if..then' [Rey] |
| Full Idea: Bifurcated logical particles (either/or, if/then) are in principle beyond the power of any local chaining device to build sentences. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 4.2.1) | |
| A reaction: True in natural languages, but not in formal ones? If P then either if-Q-then-R or if-S-then-T. Is that chaining? If rain, then if light then puddles, or if heavy then floods. Hm. |
| 5762 | The wicked want goodness, so they would not be wicked if they obtained it [Boethius] |
| Full Idea: If the wicked obtained what they want - that is goodness - they could not be wicked. | |
| From: Boethius (The Consolations of Philosophy [c.520], IV.II) | |
| A reaction: This is a nice paradox which arises from Boethius being, like Socrates, an intellectualist. The question is whether the wicked want the good de re or de dicto. If they wanted to good de re (as its true self) they would obviously not be wicked. |
| 5770 | Rewards and punishments are not deserved if they don't arise from free movement of the mind [Boethius] |
| Full Idea: If there is no free will, then in vain is reward offered to the good and punishment to the bad, because they have not been deserved by any free and willed movement of the mind. | |
| From: Boethius (The Consolations of Philosophy [c.520], V.III) | |
| A reaction: I just don't see why decisions have to come out of nowhere in order to have any merit. People are different from natural forces, because the former can be persuaded by reasons. A moral agent is a mechanism which decides according to reasons. |
| 5764 | When people fall into wickedness they lose their human nature [Boethius] |
| Full Idea: When people fall into wickedness they lose their human nature. | |
| From: Boethius (The Consolations of Philosophy [c.520], IV.III) | |
| A reaction: This is a view I find quite sympathetic, but which is a million miles from the modern view. Today's paper showed a picture of a famous criminal holding a machine gun and a baby. We seem to delight in the idea that human nature is partly wicked. |
| 5756 | Happiness is a good which once obtained leaves nothing more to be desired [Boethius] |
| Full Idea: Happiness is a good which once obtained leaves nothing more to be desired. | |
| From: Boethius (The Consolations of Philosophy [c.520], III.I) | |
| A reaction: This sounds like the ancient 'eudaimonism' of Socrates and Aristotle, which might not be entirely compatible with orthodox Christianity. It is not true, though, that happy people lack ambition. To be happy, an unfilfilled aim may be needed. |
| 5763 | The bad seek the good through desire, but the good through virtue, which is more natural [Boethius] |
| Full Idea: The supreme good is the goal of good men and bad men alike, and the good seek it by means of a natural activity - the exercise of virtue - while the bad strive to acquire it by means of their desires, which is not a natural way of obtaining the good. | |
| From: Boethius (The Consolations of Philosophy [c.520], IV.II) | |
| A reaction: Interesting here is the slightly surprising claim that the pursuit of virtue is 'natural', implying that the mere pursuit of desire is not. Doesn't nature have to be restrained to achieve the good? Boethius is in the tradition of Aristotle and stoicism. |
| 3221 | Our desires become important when we have desires about desires [Rey] |
| Full Idea: What gives people's desires certain moral importance is the fact that they have desires about those desires. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 11.1) | |
| A reaction: from Frankfurt |
| 5759 | Varied aims cannot be good because they differ, but only become good when they unify [Boethius] |
| Full Idea: The various things that men pursue are not perfect and good, because they differ from one another; ..when they differ they are not good, but when they begin to be one they become good, so it is through the acquisition of unity that these things are good. | |
| From: Boethius (The Consolations of Philosophy [c.520], III.XI) | |
| A reaction: This is a criticism of Aristotle's pluralism about the good(s) for man. Boethius' thought is appealing, and ties in with the Socratic notion that the virtues might be unified in some way. I think it is right that true virtues merge together, ideally. |
| 5754 | You can't control someone's free mind, only their body and possessions [Boethius] |
| Full Idea: The only way one man can exercise power over another is over his body and what is inferior to it, his possessions. You cannot impose anything on a free mind. | |
| From: Boethius (The Consolations of Philosophy [c.520], II.VI) | |
| A reaction: Written, of course, in prison. Boethius had not met hypnotism, or mind-controlling drugs, or invasive brain surgery. He hadn't read '1984'. He hadn't seen 'The Ipcress File'. (In fact, he should have got out more…) |
| 16692 | Divine eternity is the all-at-once and complete possession of unending life [Boethius] |
| Full Idea: Divine eternity is the all-at-once [tota simul] and complete possession of unending life. | |
| From: Boethius (The Consolations of Philosophy [c.520], V.6), quoted by Robert Pasnau - Metaphysical Themes 1274-1671 18.1 | |
| A reaction: This is a famous definition, and 'tota simul' became the phrase used for 'entia successiva', such as a day, or the Olympic Games. |
| 5752 | Where does evil come from if there is a god; where does good come from if there isn't? [Boethius] |
| Full Idea: A philosopher (possibly Epicurus) asked where evil comes from if there is a god, and where good comes from if there isn't. | |
| From: Boethius (The Consolations of Philosophy [c.520], I.IV) | |
| A reaction: A nice question. The best known answer to the first question is 'Satan'. Some would say that in the second case good is impossible, but I would have thought that the only possible answer is 'mankind'. |
| 5758 | God is the good [Boethius] |
| Full Idea: God is the good. | |
| From: Boethius (The Consolations of Philosophy [c.520], III.XI) | |
| A reaction: This summary follows on from the rather dubious discussion in Idea 5757. If God IS the good, it is not clear how God could be usefully described as 'good'. We would know that he was good a priori, without any enquiry into his nature being needed. |
| 5757 | God is the supreme good, so no source of goodness could take precedence over God [Boethius] |
| Full Idea: That which by its own nature is something distinct from supreme good, cannot be supreme good. ..It is impossible for anything to be by nature better than that from which it is derived, so that which is the origin of all things is supreme good. | |
| From: Boethius (The Consolations of Philosophy [c.520], III.X) | |
| A reaction: This is the contortion early Christians got into once they decided God had to be 'supreme' in the moral world (and every other world). Boethius allows a possible external source of all morality, but then has to say that this source is morally inferior. |
| 5760 | The power through which creation remains in existence and motion I call 'God' [Boethius] |
| Full Idea: For this power, whatever it is, through which creation remains in existence and in motion, I use the word which all people use, namely God. | |
| From: Boethius (The Consolations of Philosophy [c.520], III.XII) | |
| A reaction: An interesting caution in the phrase 'whatever it is'. Boethius would have been very open-minded in discussion with modern science about the stability of nature. Personally I reject Boethius' theory, but don't have a better one. Cf Idea 1431. |
| 5753 | The regular events of this life could never be due to chance [Boethius] |
| Full Idea: I could never believe that events of such regularity as we find in this life are due to the haphazards of chance. | |
| From: Boethius (The Consolations of Philosophy [c.520], I.VI) | |
| A reaction: It depends what you mean by 'chance'. Boethius infers a conscious mind, and presumes this to be God, but that is two large and unsupported steps. Modern atheists must acknowledge Boethius' problem. Why is there order? |
| 5765 | The reward of the good is to become gods [Boethius] |
| Full Idea: Goodness is happiness, ..but we agree that those who attain happiness are divine. The reward of the good, then, is to become gods. | |
| From: Boethius (The Consolations of Philosophy [c.520], IV.III) | |
| A reaction: Kant offered a similar argument (see Idea 1455). Most of us are unlikely to agree with the second premise of Boethius' argument. The idea that we might somehow become gods gripped the imagination for the next thousand years. |
| 5761 | God can do anything, but he cannot do evil, so evil must be nothing [Boethius] |
| Full Idea: 'There is nothing that an omnipotent power could not do?' 'No.' 'Then can God do evil?' 'No.' 'So evil is nothing, since that is what He cannot do who can do anthing.' | |
| From: Boethius (The Consolations of Philosophy [c.520], III.XII) | |
| A reaction: A lovely example of the contortions necessary once you insist that God must be 'omnipotent', in some absolute sense of the term. Saying that evil is 'nothing' strikes me as nothing more than a feeble attempt to insult it. |
| 5766 | If you could see the plan of Providence, you would not think there was evil anywhere [Boethius] |
| Full Idea: If you could see the plan of Providence, you would not think there was evil anywhere. | |
| From: Boethius (The Consolations of Philosophy [c.520], IV.VI) | |
| A reaction: This brings out the verificationist in me. See Idea 1467, by Antony Flew. Presumably Boethius would retain his faith as Europe moved horribly from 1939 to 1945, and even if the whole of humanity sank into squalid viciousness. |
