23890 | For Plato true wisdom is supernatural [Plato, by Weil] |
Full Idea: It is evident that Plato regards true wisdom as something supernatural. | |
From: report of Plato (works [c.375 BCE]) by Simone Weil - God in Plato p.61 | |
A reaction: Taken literally, I assume this is wrong, but we can empathise with the thought. Wisdom has the feeling of rising above the level of mere knowledge, to achieve the overview I associate with philosophy. |
3060 | Plato never mentions Democritus, and wished to burn his books [Plato, by Diog. Laertius] |
Full Idea: Plato, who mentions nearly all the ancient philosophers, nowhere speaks of Democritus; he wished to burn all of his books, but was persuaded that it was futile. | |
From: report of Plato (works [c.375 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 09.7.8 |
23891 | Two contradictories force us to find a relation which will correlate them [Plato, by Weil] |
Full Idea: Where contradictions appear there is a correlation of contraries, which is relation. If a contradiction is imposed on the intelligence, it is forced to think of a relation to transform the contradiction into a correlation, which draws the soul higher. | |
From: report of Plato (works [c.375 BCE]) by Simone Weil - God in Plato p.70 | |
A reaction: A much better account of the dialectic than anything I have yet seen in Hegel. For the first time I see some sense in it. A contradiction is not a falsehood, and it must be addressed rather than side-stepped. A kink in the system, that needs ironing. |
14502 | Plato's idea of 'structure' tends to be mathematically expressed [Plato, by Koslicki] |
Full Idea: 'Structure' tends to be characterized by Plato as something that is mathematically expressed. | |
From: report of Plato (works [c.375 BCE]) by Kathrin Koslicki - The Structure of Objects V.3 iv | |
A reaction: [Koslicki is drawing on Verity Harte here] |
17948 | Plato's Forms meant that the sophists only taught the appearance of wisdom and virtue [Plato, by Nehamas] |
Full Idea: Plato's theory of Forms allowed him to claim that the sophists and other opponents were trapped in the world of appearance. What they therefore taught was only apparent wisdom and virtue. | |
From: report of Plato (works [c.375 BCE]) by Alexander Nehamas - Eristic,Antilogic,Sophistic,Dialectic p.118 |
3039 | When Diogenes said he could only see objects but not their forms, Plato said it was because he had eyes but no intellect [Plato, by Diog. Laertius] |
Full Idea: When Diogenes told Plato he saw tables and cups, but not 'tableness' and 'cupness', Plato replied that this was because Diogenes had eyes but no intellect. | |
From: report of Plato (works [c.375 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 06.2.6 |
20906 | Platonists argue for the indivisible triangle-in-itself [Plato, by Aristotle] |
Full Idea: The Platonists, on the basis of purely logical arguments, posit the existence of an indivisible 'triangle in itself'. | |
From: report of Plato (works [c.375 BCE]) by Aristotle - Coming-to-be and Passing-away (Gen/Corr) 316a15 | |
A reaction: A helpful confirmation that geometrical figures really are among the Forms (bearing in mind that numbers are not, because they contain one another). What shape is the Form of the triangle? |
556 | If there is one Form for both the Form and its participants, they must have something in common [Aristotle on Plato] |
Full Idea: If there is the same Form for the Forms and for their participants, then they must have something in common. | |
From: comment on Plato (works [c.375 BCE]) by Aristotle - Metaphysics 991a |
563 | If gods are like men, they are just eternal men; similarly, Forms must differ from particulars [Aristotle on Plato] |
Full Idea: We say there is the form of man, horse and health, but nothing else, making the same mistake as those who say that there are gods but that they are in the form of men. They just posit eternal men, and here we are not positing forms but eternal sensibles. | |
From: comment on Plato (works [c.375 BCE]) by Aristotle - Metaphysics 997b |
557 | A Form is a cause of things only in the way that white mixed with white is a cause [Aristotle on Plato] |
Full Idea: A Form is a cause of things only in the way that white mixed with white is a cause. | |
From: comment on Plato (works [c.375 BCE]) by Aristotle - Metaphysics 991a |
565 | The Forms cannot be changeless if they are in changing things [Aristotle on Plato] |
Full Idea: The Forms could not be changeless if they were in changing things. | |
From: comment on Plato (works [c.375 BCE]) by Aristotle - Metaphysics 998a |
9607 | The greatest discovery in human thought is Plato's discovery of abstract objects [Brown,JR on Plato] |
Full Idea: The greatest discovery in the history of human thought is Plato's discovery of abstract objects. | |
From: comment on Plato (works [c.375 BCE]) by James Robert Brown - Philosophy of Mathematics Ch. 2 | |
A reaction: Compare Idea 2860! Given the diametrically opposed views, it is clearly likely that Plato's central view is the most important idea in the history of human thought, even if it is wrong. |
13263 | We can grasp whole things in science, because they have a mathematics and a teleology [Plato, by Koslicki] |
Full Idea: Due to the mathematical nature of structure and the teleological cause underlying the creation of Platonic wholes, these wholes are intelligible, and are in fact the proper objects of science. | |
From: report of Plato (works [c.375 BCE]) by Kathrin Koslicki - The Structure of Objects 5.3 | |
A reaction: I like this idea, because it pays attention to the connection between how we conceive objects to be, and how we are able to think about objects. Only examining these two together enables us to grasp metaphysics. |
13261 | Plato sees an object's structure as expressible in mathematics [Plato, by Koslicki] |
Full Idea: The 'structure' of an object tends to be characterised by Plato as something that is mathematically expressible. | |
From: report of Plato (works [c.375 BCE]) by Kathrin Koslicki - The Structure of Objects 5.3 | |
A reaction: This seems to be pure Pythagoreanism (see Idea 644). Plato is pursuing Pythagoras's research programme, of trying to find mathematics buried in every aspect of reality. |
13265 | Plato was less concerned than Aristotle with the source of unity in a complex object [Plato, by Koslicki] |
Full Idea: Plato was less concerned than Aristotle with the project of how to account, in completely general terms, for the source of unity within a mereologically complex object. | |
From: report of Plato (works [c.375 BCE]) by Kathrin Koslicki - The Structure of Objects 5.5 | |
A reaction: Plato seems to have simply asserted that some sort of harmony held things together. Aristotles puts the forms [eidos] within objects, rather than external, so he has to give a fuller account of what is going on in an object. He never managed it! |
593 | Plato's holds that there are three substances: Forms, mathematical entities, and perceptible bodies [Plato, by Aristotle] |
Full Idea: Plato's doctrine was that the Forms and mathematicals are two substances and that the third substance is that of perceptible bodies. | |
From: report of Plato (works [c.375 BCE]) by Aristotle - Metaphysics 1028b |
13260 | Plato says wholes are either containers, or they're atomic, or they don't exist [Plato, by Koslicki] |
Full Idea: Plato considers a 'container' model for wholes (which are disjoint from their parts) [Parm 144e3-], and a 'nihilist' model, in which only wholes are mereological atoms, and a 'bare pluralities' view, in which wholes are not really one at all. | |
From: report of Plato (works [c.375 BCE]) by Kathrin Koslicki - The Structure of Objects 5.2 | |
A reaction: [She cites Verity Harte for this analysis of Plato] The fourth, and best, seems to be that wholes are parts which fall under some unifying force or structure or principle. |
11237 | Only universals have essence [Plato, by Politis] |
Full Idea: Plato argues that only universals have essence. | |
From: report of Plato (works [c.375 BCE]) by Vassilis Politis - Aristotle and the Metaphysics 1.4 |
11238 | Plato and Aristotle take essence to make a thing what it is [Plato, by Politis] |
Full Idea: Plato and Aristotle have a shared general conception of essence: the essence of a thing is what that thing is simply in virtue of itself and in virtue of being the very thing it is. It answers the question 'What is this very thing?' | |
From: report of Plato (works [c.375 BCE]) by Vassilis Politis - Aristotle and the Metaphysics 1.4 |
3296 | Sense-data are a false objectification of what is essentially subjective [Nagel] |
Full Idea: The private object or sense datum view is an instance of the false objectification of what is essentially subjective. | |
From: Thomas Nagel (Subjective and Objective [1979], p.207) |
7871 | Perceptual concepts can't just refer to what causes classification [Papineau] |
Full Idea: We may say that a perceptual concept refers to that entity which normally causes classificatory uses of that concept...but this won't work because such deployments are often caused by things which the concept doesn't refer to. A model might cause 'bird'. | |
From: David Papineau (Thinking about Consciousness [2002], 4.6) | |
A reaction: This rejects the causal theory of perceptual concepts. I like the approach, because classifying things strikes me as absolutely basic to what brains do. To see that x is a bird is to place x in the class of birds. |
17085 | A good explanation totally rules out the opposite explanation (so Forms are required) [Plato, by Ruben] |
Full Idea: For Plato, an acceptable explanation is one such that there is no possibility of there being the opposite explanation at all, and he thought that only explanations in terms of the Forms, but never physical explanations, could meet this requirement. | |
From: report of Plato (works [c.375 BCE]) by David-Hillel Ruben - Explaining Explanation Ch 2 | |
A reaction: [Republic 436c is cited] |
3295 | Inner v outer brings astonishment that we are a particular person [Nagel] |
Full Idea: The problem of reconciling the objective and subjective points of view takes its purest form in a sense of incredulity that one should be anyone in particular. | |
From: Thomas Nagel (Subjective and Objective [1979], p.206) | |
A reaction: Nice observation. This idea has always struck me forcibly, and seems to be one of those basic intuitions which motivates philosophy, and yet the subject has almost nothing to say about it. Of course you are you, or you wouldn't be amazed by it… |
7852 | The only serious mind-brain theories now are identity, token identity, realization and supervenience [Papineau] |
Full Idea: Anybody writing seriously about mind-brain issues nowadays needs to explain whether they think of materialism in terms of identity, token identity, realization, or supervenience. | |
From: David Papineau (Thinking about Consciousness [2002], Intro §6) | |
A reaction: Dualists are not invited. Functionalists are attending a different party. I wonder if his four categories collapse into two: the token/supervenience view, and the identity/realization view? |
7864 | Maybe mind and body do overdetermine acts, but are linked (for some reason) [Papineau] |
Full Idea: Maybe physical effects of mental causes are always overdetermined by distinct causes (the 'belt and braces' view). Defenders say the two are still counterfactually dependent - but that would raise the question of why, if they are ontologically distinct. | |
From: David Papineau (Thinking about Consciousness [2002], 1.5) | |
A reaction: [He cites D.H. Mellor as defending 'belt and braces'] This strikes me as the sort of theory that arises from desperation: traditional dualism won't work, but we MUST keep mind separate, so that we can have free will, and save morality. All very confused! |
7873 | Young children can see that other individuals sometimes have false beliefs [Papineau] |
Full Idea: The classic manifestation of being able to think about other individuals' mental states is success on the 'false belief test', which requires attribution of mistaken representations to other agents. Children aged three or four can do this. | |
From: David Papineau (Thinking about Consciousness [2002], 4.7) | |
A reaction: There may be an other minds problem, but there is empirical evidence that we can 'read' the minds of others (from their behaviour) even if other animals can't. That seems to be clear, even if folk psychology is fiction, and we make mistakes. |
7874 | Do we understand other minds by simulation-theory, or by theory-theory? [Papineau] |
Full Idea: There is debate about whether we attribute beliefs and desires to others, and predict their behaviour, by simulating the decisions we would make ourselves ('simulation-theory'), or by deducing them from some general theory ('theory-theory'). | |
From: David Papineau (Thinking about Consciousness [2002], 4.7) | |
A reaction: Could be both. If someone is hurt, empathy leads to direct mind-reading (which seems like simulation), but if someone is behaving strangely we may have to bring theories to bear, because this person seems to be different. |
7882 | Researching phenomenal consciousness is peculiar, because the concepts involved are peculiar [Papineau] |
Full Idea: It is a mistake to suppose that research into phenomenal consciousness can proceed just like other kinds of scientific research. Phenomenal concepts are peculiar, and some of the questions they pose for empirical investigation are peculiar too. | |
From: David Papineau (Thinking about Consciousness [2002], 7.01) | |
A reaction: This arises from Papineau's Conceptual Dualism, that our concepts are deeply dualist, when the underlying ontology is not. Brain researchers are wise to ignore phenomenology, and creep slowly forward from the physical end, where the concepts are clear. |
7854 | Whether octopuses feel pain is unclear, because our phenomenal concepts are too vague [Papineau] |
Full Idea: Our phenomenal concepts are irredeemably vague in certain dimensions, in ways that preclude there being any fact of the matter about whether octopuses feel phenomenal pain, or silicon-based humanoids would have any phenomenal consciousness. | |
From: David Papineau (Thinking about Consciousness [2002], Intro §7) | |
A reaction: It would be hard for Papineau to prove this point, but clearly our imagination finds it very hard to grasp the idea of a thing which is 'somewhat conscious'. The concept of being much more conscious than humans also bewilders us. |
7889 | Our concept of consciousness is crude, and lacks theoretical articulation [Papineau] |
Full Idea: Our phenomenal concept of consciousness-as-such is a crude tool, lacking theoretical articulation | |
From: David Papineau (Thinking about Consciousness [2002], 7.13) | |
A reaction: This is a point well made. Given that the human brain is the most complex thing (for its size) in the known universe, we shouldn't expect it to divide up into three or four clear-cut activities. Compare the precision of 'geography' as a concept. |
7891 | We can’t decide what 'conscious' means, so it is undecidable whether cats are conscious [Papineau] |
Full Idea: If consciousness is availability for HOT judgements, then cats are not conscious, but if it consists in attention, then they are. I say the concept of consciousness is indefinite between the two, so there is no fact about whether cats are conscious. | |
From: David Papineau (Thinking about Consciousness [2002], 7.16) | |
A reaction: Nice point. My personal view is that the question of whether cats are conscious is hopeless because philosophers insist on making consciousness all-or-nothing (e.g. Idea 5786). If I experienced cat mentality, I might say I was 'semi-conscious'. |
7890 | Maybe a creature is conscious if its mental states represent things in a distinct way [Papineau] |
Full Idea: The thesis of 'representational theories of consciousness' is that a creature is conscious just in case it is in a certain kind of representational state, some state which represents in a certain way. | |
From: David Papineau (Thinking about Consciousness [2002]) | |
A reaction: [He cites Harman, Dretske and Tye] The immediate impediment I see to this view is the extreme difficulty of explaining what the special 'way' is that turns representations into consciousness. Some mental states are not representational, and vice versa. |
7885 | The 'actualist' HOT theory says consciousness comes from actual higher judgements of mental states [Papineau] |
Full Idea: The 'actualist' HOT theory says that a state is conscious if the subject is 'aware' of it, where this is understood as a matter of the subject forming some actual Higher-Order judgement about it. | |
From: David Papineau (Thinking about Consciousness [2002], 7.11) | |
A reaction: As stated there seems an obvious regress problem. Is the consciousness in the mental state, or in the higher awareness of it? If the former, how does being observed make it conscious? If the latter, what gives the higher level its consciousness? |
7886 | Actualist HOT theories imply that a non-conscious mental event could become conscious when remembered [Papineau] |
Full Idea: Actualist HOT theories face an awkward problem with memory judgements: ...how can an earlier mental state be rendered conscious by some later act of memory? As when I see a red pillar box with no higher-order judgement, and then recall it later. | |
From: David Papineau (Thinking about Consciousness [2002], 7.11) | |
A reaction: [See 7886 for 'Actualist' HOT theories] This is not altogether absurd. A red pillar box could be somewhere in my field of vision, and then I might suddenly become conscious of it (if it moved!). Police interrogation reminds me of what I only glimpsed. |
7887 | States are conscious if they could be the subject of higher-order mental judgements [Papineau] |
Full Idea: The 'dispositional' HOT thesis says that a state is conscious just in case it could have been the subject of an introspective Higher-Order judgement, even if it wasn't actually so subject. | |
From: David Papineau (Thinking about Consciousness [2002], 7.13) | |
A reaction: [He cites Dennett and Carruthers for this view] This is designed to meet other problems, but it sounds odd. Does it really make no difference whether higher-judgement actually occurs? How can conscious events be distinguished once they've gone? |
7888 | Higher-order judgements may be possible where the subject denies having been conscious [Papineau] |
Full Idea: Dispositional Higher-Order judgeability will be present in some cases which the empirical methodology catalogues as not conscious (as when a subject denies having heard a sound, or seen a bird). | |
From: David Papineau (Thinking about Consciousness [2002], 7.13) | |
A reaction: (This attacks Idea 7887) This confirms my intuition, that we can be quite unconscious of things which can still be recalled at a later date. Of course, one could always challenge the reliability of the subject's report in such a case. |
3293 | If you assert that we have an ego, you can still ask if that future ego will be me [Nagel] |
Full Idea: The metaphysical ego, if it is a continuing individual with its identity over time, is just one more thing about which the same problem can be raised - will that ego still be me? | |
From: Thomas Nagel (Subjective and Objective [1979], p.200) | |
A reaction: You can worry too much about some philosophical questions. If it is me now, and it has continuing individual identity over time, I'm not going to lose sleep over the possibility that it might nevertheless somehow cease to be me. I'm overrated. |
3292 | The most difficult problem of free will is saying what the problem is [Nagel] |
Full Idea: The most difficult problem of free will is saying what the problem is. | |
From: Thomas Nagel (Subjective and Objective [1979], p.198) |
7860 | The epiphenomenal relation of mind and brain is a 'causal dangler', unlike anything else [Papineau] |
Full Idea: If epiphenomenalism were true, then the relation between mind and brain would be like nothing else in nature. After all, science recognises no other examples of 'causal danglers', ontologically independent states with causes but no effects. | |
From: David Papineau (Thinking about Consciousness [2002], 1.4) | |
A reaction: This would be a good enough reason for me to reject the epiphenomenalist view, even if I thought it was a coherent proposal. Insofar as it proposes the existence of something (mind) with no causal powers at all, it strikes me as nonsense. |
7862 | Maybe minds do not cause actions, but do cause us to report our decisions [Papineau] |
Full Idea: Even if conscious decisions did not contribute causally to the actions normally attributed to them, they would still presumably be the causes of the sounds I make when I later report my earlier conscious decisions. | |
From: David Papineau (Thinking about Consciousness [2002], 1.4) | |
A reaction: This is a good reply to my view (borrowed from Dennett - Idea 7379), that epiphenomalism proposes an absurdity (an entity with no causal powers). But if mind can cause speech, why could it not cause arm movements? |
7870 | Role concepts either name the realising property, or the higher property constituting the role [Papineau] |
Full Idea: Role concepts can be of two kinds: they can name whichever property realises the role, or they can name the higher property which constitutes the role. | |
From: David Papineau (Thinking about Consciousness [2002], 4.2 n1) | |
A reaction: This points strikes me as being crucial to discussions of mental functions. Perhaps labels of Realising Properties and Constituting Properties would help. Analytical philosophy rules. |
7858 | If causes are basic particulars, this doesn't make conscious and physical properties identical [Papineau] |
Full Idea: If causes are basic particulars, then the causal argument won't carry you to the identity of conscious and physical properties, since this only requires them to be instantiated in the same particular, not that the properties are themselves identical. | |
From: David Papineau (Thinking about Consciousness [2002], 1.3) | |
A reaction: [See Idea 7857; Papineau is rejecting the Davidson view] This explains how Davidson reaches a token-token identity view. Can two events occur in the same particular at the same moment? Depends what you mean by a 'particular'. |
7865 | Supervenience can be replaced by identifying mind with higher-order or disjunctional properties [Papineau] |
Full Idea: I would argue that any benefits offered by the notion of supervenience are more easily gained simply by identifying mental properties directly with higher-order properties or disjunctions of physical properties. | |
From: David Papineau (Thinking about Consciousness [2002], 1.8) | |
A reaction: Those who talk of supervenience seem to me to have retreated into a mystery that is not far from substance dualism. We want the explanation of a supervenience. If you accompany me everywhere, I think you are stalking me, or are tied to my ankle. |
7892 | The completeness of physics is needed for mind-brain identity [Papineau] |
Full Idea: Without the completeness of physics, there is no compelling reason to identify the mind with the brain. | |
From: David Papineau (Thinking about Consciousness [2002], App 7) | |
A reaction: Papineau says the completeness of physics was accepted from the 1950s. Why were Epicurus and Hobbes physicalists? Do we have a circularity here? How do you establish the completeness of physics, without asserting mind to be physical? |
7879 | Mind-brain reduction is less explanatory, because phenomenal concepts lack causal roles [Papineau] |
Full Idea: Mind-brain reductions are less explanatory than characteristic reductions in other areas of science, ...because phenomenal concepts have no special associations with causal roles. | |
From: David Papineau (Thinking about Consciousness [2002], 5.3) | |
A reaction: This may always have some truth in it, but I would expect reductive accounts in the far future to get much closer to giving explanations of phenomenal experience. We can't work down from the phenomenal end, but we can work up from the physical/causal end. |
20971 | Weak reduction of mind is to physical causes; strong reduction is also to physical laws [Papineau] |
Full Idea: Weak reduction of mind requires only that mental causes be identified with physical causes. A strong reduction requires also that the laws by which such causes operate follow by composition from non-special laws. | |
From: David Papineau (Thinking about Consciousness [2002], App 3 n8) | |
A reaction: I'm cautious about laws, but I still vote for strong reduction. No new principles are needed to make a mind from a brain. |
7856 | It is absurd to think that physical effects are caused twice, so conscious causes must be physical [Papineau] |
Full Idea: Many effects that we attribute to conscious causes have full physical causes. But it would be absurd to suppose that these effects are caused twice over. So the conscious causes must be identical to some part of those physical causes. | |
From: David Papineau (Thinking about Consciousness [2002], 1.2) | |
A reaction: [Papineau labelled this the Causal Argument] Of course two causes can combine to produce an effect, and there can be redundant physical overcausation, but in general I think this is a good argument. |
7881 | Accept ontological monism, but conceptual dualism; we think in a different way about phenomenal thought [Papineau] |
Full Idea: We should be ontological monists, but we should be conceptual dualists. We need to recognise a special phenomenal way of thinking about conscious properties, if we are to dispel the confusions that persuade us that conscious properties cannot be material. | |
From: David Papineau (Thinking about Consciousness [2002], 7.01) | |
A reaction: This idea came to me as a revelation, and strikes me as spot on. We have developed conceptual dualism simply because humans cannot directly see that their thinking is actually physical brain activity. Thought seems ungrounded, and utterly different. |
7866 | Mary acquires new concepts; she previously thought about the same property using material concepts [Papineau] |
Full Idea: While there is indeed a before-after difference in Mary, this is just a matter of coming to think in new ways, and acquiring a new concept. There is no new experiential property. She could think about the property perfectly well, using material concepts. | |
From: David Papineau (Thinking about Consciousness [2002], 2.2) | |
A reaction: I think it is better to talk of Mary encountering a new mode of experiencing something, just as experience becomes blurred when glasses are removed. No one acquires new 'knowledge' of blurred objects when they remove their glasses. |
7850 | Thinking about a thing doesn't require activating it [Papineau] |
Full Idea: Thinking about something doesn't require activating some version of it. | |
From: David Papineau (Thinking about Consciousness [2002], Intro §5) | |
A reaction: E.g. I can discuss 'red' without visualising it. This observation strikes me as simple and basic to what thinking is. Papineau thinks that confusion about this simple point leads to major errors in the philosophy of mind. |
7851 | Consciousness affects bodily movement, so thoughts must be material states [Papineau] |
Full Idea: Conscious states clearly affect our bodily movements. But surely anything that so produces a material effect must itself be a material state. | |
From: David Papineau (Thinking about Consciousness [2002], Intro §6) | |
A reaction: This is Papineau's simplest possible statement of what he calls the Causal Argument, which he considers to be a knock-down argument for materialism. I agree, but it is really only an intuition. You never know... |
1651 | Plato wanted to somehow control and purify the passions [Vlastos on Plato] |
Full Idea: Plato put high on his agenda a project which did not figure in Socrates' programme at all: the hygienic conditioning of the passions. This cannot be an intellectual process, as argument cannot touch them. | |
From: comment on Plato (works [c.375 BCE]) by Gregory Vlastos - Socrates: Ironist and Moral Philosopher p.88 | |
A reaction: This is the standard traditional view of any thinker who exaggerates the importance and potential of reason in our lives. |
7884 | Most reductive accounts of representation imply broad content [Papineau] |
Full Idea: Broadness of content is sometimes defended purely on intuitive grounds, but it is also a corollary of most reductive accounts of representation, including standard teleosemantic and causal accounts. | |
From: David Papineau (Thinking about Consciousness [2002]) | |
A reaction: (For Causal and Teleosemantic views, see Idea 7871, Idea 7872) Presumably a causal/purposeful relationship would only make sense if both halves of the relationship were specified. I suspect this is obscured by over-simplifications. Cf Idea 6634! |
7863 | If content hinges on matters outside of you, how can it causally influence your actions? [Papineau] |
Full Idea: How can 'broad contents', which hinge on matters outside your head, exert a causal influence on your bodily movements? Surely your bodily movements are causally influenced solely by matters inside your skin, not by how matters are outside you. | |
From: David Papineau (Thinking about Consciousness [2002], 1.4) | |
A reaction: This supports my suspicion that there are some extremely simplistic interpretations of the Twin Earth case floating around. If Putnam means by 'elm' whatever experts mean, it is still his idea of what counts as an expert view. |
7883 | Verificationists tend to infer indefinite answers from undecidable questions [Papineau] |
Full Idea: The verificationist sin is to infer an indefiniteness of answers immediately from the undecidability of questions. | |
From: David Papineau (Thinking about Consciousness [2002], 7.02) | |
A reaction: This remark is aimed at Dummett's anti-realism. It strikes me that what is being described really is a sort of arrogance, in believing that reality can somehow be inferred from studying the epistemic apparatus of a few miserable little mammals. |
7872 | Teleosemantics equates meaning with the item the concept is intended to track [Papineau] |
Full Idea: The teleosemantic view of perceptual concepts is that the referential value of the concept can be equated with those items which it is the biological function of the concept to track. | |
From: David Papineau (Thinking about Consciousness [2002], 4.6) | |
A reaction: This seems to work quite nicely for 'bird', which is concept which is used to track birds. It might even work for complex entities, or abstract entities, or even negative entities. Imagination must play a role in that last one. |
7869 | Truth conditions in possible worlds can't handle statements about impossibilities [Papineau] |
Full Idea: Basing content on possible worlds that result in truth leaves no room for thoughts about genuine impossibilities, since there are not possible worlds whose actuality would make an 'impossible thought' true. | |
From: David Papineau (Thinking about Consciousness [2002], 3.7) | |
A reaction: Negative existentials like 'no rabbits in this room' and 'no snakes in this room' seem to have the same truth conditions as well. I suppose the sentences must be translated into a logical form which suits the theory, with negation stuck on the end. |
7868 | Thought content is possible worlds that make the thought true; if that includes the actual world, it's true [Papineau] |
Full Idea: The content of our thoughts can be equated with those possible worlds whose actuality would make the thought true. On this model, a true thought is one whose content includes the actual world, while a false thought is one whose content does not. | |
From: David Papineau (Thinking about Consciousness [2002], 3.7) | |
A reaction: This is the possible worlds semantics version of truth conditions theories of meaning. Papineau offers a nice difficulty for the theory (Idea 7869). Dummett says the whole approach is circular, because content precedes truth. |
3324 | Plato's whole philosophy may be based on being duped by reification - a figure of speech [Benardete,JA on Plato] |
Full Idea: Plato is liable to the charge of having been duped by a figure of speech, albeit the most profound of all, the trope of reification. | |
From: comment on Plato (works [c.375 BCE]) by José A. Benardete - Metaphysics: the logical approach Ch.12 | |
A reaction: That might be a plausible account if his view was ridiculous, but given how many powerful friends Plato has, especially in the philosophy of mathematics, we should assume he was cleverer than that. |
7503 | Plato never refers to examining the conscience [Plato, by Foucault] |
Full Idea: Plato never speaks of the examination of conscience - never! | |
From: report of Plato (works [c.375 BCE]) by Michel Foucault - On the Genealogy of Ethics p.276 | |
A reaction: Plato does imply some sort of self-evident direct knowledge about that nature of a healthy soul. Presumably the full-blown concept of conscience is something given from outside, from God. In 'Euthyphro', Plato asserts the primacy of morality (Idea 337). |
2173 | As religion and convention collapsed, Plato sought morals not just in knowledge, but in the soul [Williams,B on Plato] |
Full Idea: Once gods and fate and social expectation were no longer there, Plato felt it necessary to discover ethics inside human nature, not just as ethical knowledge (Socrates' view), but in the structure of the soul. | |
From: comment on Plato (works [c.375 BCE]) by Bernard Williams - Shame and Necessity II - p.43 | |
A reaction: anti Charles Taylor |
9274 | Plato's legacy to European thought was the Good, the Beautiful and the True [Plato, by Gray] |
Full Idea: Plato's legacy to European thought was a trio of capital letters - the Good, the Beautiful and the True. | |
From: report of Plato (works [c.375 BCE]) by John Gray - Straw Dogs 2.8 | |
A reaction: It seems to have been Baumgarten who turned this into a slogan (Idea 8117). Gray says these ideals are lethal, but I identify with them very strongly, and am quite happy to see the good life as an attempt to find the right balance between them. |
94 | Pleasure is better with the addition of intelligence, so pleasure is not the good [Plato, by Aristotle] |
Full Idea: Plato says the life of pleasure is more desirable with the addition of intelligence, and if the combination is better, pleasure is not the good. | |
From: report of Plato (works [c.375 BCE]) by Aristotle - Nicomachean Ethics 1172b27 | |
A reaction: It is obvious why we like pleasure, but not why intelligence makes it 'better'. Maybe it is just because we enjoy intelligence? |
17947 | Plato decided that the virtuous and happy life was the philosophical life [Plato, by Nehamas] |
Full Idea: Plato came to the conclusion that virtue and happiness consist in the life of philosophy itself. | |
From: report of Plato (works [c.375 BCE]) by Alexander Nehamas - Eristic,Antilogic,Sophistic,Dialectic p.117 | |
A reaction: This view is obviously ridiculous, because it largely excludes almost the entire human race, which sees philosophy as a cul-de-sac, even if it is good. But virtue and happiness need some serious thought. |
6015 | Plato, unusually, said that theoretical and practical wisdom are inseparable [Plato, by Kraut] |
Full Idea: Two virtues that are ordinarily kept distinct - theoretical and practical wisdom - are joined by Plato; he thinks that neither one can be fully possessed unless it is combined with the other. | |
From: report of Plato (works [c.375 BCE]) by Richard Kraut - Plato | |
A reaction: I get the impression that this doctrine comes from Socrates, whose position is widely reported as 'intellectualist'. Aristotle certainly held the opposite view. |
3294 | As far as possible we should become instruments to realise what is best from an eternal point of view [Nagel] |
Full Idea: The right thing to do is to turn oneself as far as possible into an instrument for the realisation of what is best 'sub specie aeternitatis'. | |
From: Thomas Nagel (Subjective and Objective [1979], p.204) |
2912 | Plato is boring [Nietzsche on Plato] |
Full Idea: Plato is boring. | |
From: comment on Plato (works [c.375 BCE]) by Friedrich Nietzsche - Twilight of the Idols 9.2 |
7853 | Causation is based on either events, or facts, or states of affairs [Papineau] |
Full Idea: Any serious theory of the mind-brain must explain whether it thinks of causation in terms of events, facts, or states of affairs. | |
From: David Papineau (Thinking about Consciousness [2002], Intro §6) | |
A reaction: I instantly prefer events, simply because they can be specified a little more precisely than the other two. Since cause has a direction in time, it would be nice to specify the times of its components, and events have times. |
7857 | Causes are instantiations of properties by particulars, or they are themselves basic particulars [Papineau] |
Full Idea: One view of causes is that they are facts, or instantiations of properties (maybe by particulars, making them 'Kim-events'); the alternative view is that causes themselves are basic particulars ('Davidson-events'). | |
From: David Papineau (Thinking about Consciousness [2002], 1.3) | |
A reaction: Like Papineau, I incline to the Kim view. It is too easy for philosophers to treat key ideas as unanalysable axioms of thought. An event typically has components and features. It is a contingent matter whether there are any events. |
20976 | The completeness of physics cannot be proved [Papineau] |
Full Idea: There is no knock down argument for the completeness of physics. | |
From: David Papineau (Thinking about Consciousness [2002], App 7) | |
A reaction: This is commendably honest, given that he pins his view of the mind on it. He makes the case sound overwhelming, though. The thing which would breach the completeness is like the Loch Ness monster - you can't prove it isn't there, if it hides. |
20970 | Determinism is possible without a complete physics, if mental forces play a role [Papineau] |
Full Idea: We can accept determinism without accepting physical determinism, and so without accepting the completeness of physics. ...We can have a deterministic model in which sui generis mental forces play an essential role. | |
From: David Papineau (Thinking about Consciousness [2002], App 3) | |
A reaction: Papineau cites (on p.241) the 18th century biologist Robert Whytt as an example of this view. |
20974 | Modern biological research, especially into the cell, has revealed no special new natural forces [Papineau] |
Full Idea: In the 1950s a great deal became known about biochemical and neurophysiological processes, especially at the level of the cell, and none of it gave any evidence for the existence of special forces not found elsewhere in nature. | |
From: David Papineau (Thinking about Consciousness [2002], A 6) | |
A reaction: Papineau says that this plus the conservation of energy makes the closure of physics faily conclusive. I would think the similar failure of modern research into the brain to find evidence of weird forces strengthens the case. |
20975 | Quantum 'wave collapses' seem to violate conservation of energy [Papineau] |
Full Idea: The conservation of energy is apparently violated by 'wave collapses' in quantum systems. | |
From: David Papineau (Thinking about Consciousness [2002], A 7 n15) | |
A reaction: One could imagine it being a little harder to verify the conservation of energy at the quantum levels, where particles and anti-particles pop in and out of existence. I've been wondering why there is some suspicion of collapses. |
1526 | Almost everyone except Plato thinks that time could not have been generated [Plato, by Aristotle] |
Full Idea: With a single exception (Plato) everyone agrees about time - that it is not generated. Democritus says time is an obvious example of something not generated. | |
