| 6859 | Analytic philosophy has much higher standards of thinking than continental philosophy [Williamson] |
| Full Idea: Certain advances in philosophical standards have been made within analytic philosophy, and there would be a serious loss of integrity involved in abandoning them in the way required to participate in current continental philosophy. | |
| From: Timothy Williamson (Interview with Baggini and Stangroom [2001], p.151) | |
| A reaction: The reply might be to concede the point, but say that the precision and rigour achieved are precisely what debar analytical philosophy from thinking about the really interesting problems. One might as well switch to maths and have done with it. |
| 6862 | Fuzzy logic uses a continuum of truth, but it implies contradictions [Williamson] |
| Full Idea: Fuzzy logic is based on a continuum of degrees of truth, but it is committed to the idea that it is half-true that one identical twin is tall and the other twin is not, even though they are the same height. | |
| From: Timothy Williamson (Interview with Baggini and Stangroom [2001], p.154) | |
| A reaction: Maybe to be shocked by a contradiction is missing the point of fuzzy logic? Half full is the same as half empty. The logic does not say the twins are different, because it is half-true that they are both tall, and half-true that they both aren't. |
| 6858 | Formal logic struck me as exactly the language I wanted to think in [Williamson] |
| Full Idea: As soon as I started learning formal logic, that struck me as exactly the language that I wanted to think in. | |
| From: Timothy Williamson (Interview with Baggini and Stangroom [2001]) | |
| A reaction: It takes all sorts… It is interesting that formal logic might be seen as having the capacity to live up to such an aspiration. I don't think the dream of an ideal formal language is dead, though it will never encompass all of reality. Poetic truth. |
| 6863 | Close to conceptual boundaries judgement is too unreliable to give knowledge [Williamson] |
| Full Idea: If one is very close to a conceptual boundary, then one's judgement will be too unreliable to constitute knowledge, and therefore one will be ignorant. | |
| From: Timothy Williamson (Interview with Baggini and Stangroom [2001], p.156) | |
| A reaction: This is the epistemological rather than ontological interpretation of vagueness. It sounds very persuasive, but I am reluctant to accept that reality is full of very precise boundaries which we cannot quite discriminate. |
| 9476 | If dispositions are more fundamental than causes, then they won't conceptually reduce to them [Bird on Lewis] |
| Full Idea: Maybe a disposition is a more fundamental notion than a cause, in which case Lewis has from the very start erred in seeking a causal analysis, in a traditional, conceptual sense, of disposition terms. | |
| From: comment on David Lewis (Causation [1973]) by Alexander Bird - Nature's Metaphysics 2.2.8 | |
| A reaction: Is this right about Lewis? I see him as reducing both dispositions and causes to a set of bald facts, which exist in possible and actual worlds. Conditionals and counterfactuals also suffer the same fate. |
| 6861 | What sort of logic is needed for vague concepts, and what sort of concept of truth? [Williamson] |
| Full Idea: The problem of vagueness is the problem of what logic is correct for vague concepts, and correspondingly what notions of truth and falsity are applicable to vague statements (does one need a continuum of degrees of truth, for example?). | |
| From: Timothy Williamson (Interview with Baggini and Stangroom [2001], p.153) | |
| A reaction: This certainly makes vagueness sound like one of the most interesting problems in all of philosophy, though also one of the most difficult. Williamson's solution is that we may be vague, but the world isn't. |
| 8425 | For true counterfactuals, both antecedent and consequent true is closest to actuality [Lewis] |
| Full Idea: A counterfactual is non-vacuously true iff it takes less of a departure from actuality to make the consequent true along with the antecedent than it does to make the antecedent true without the consequent. | |
| From: David Lewis (Causation [1973], p.197) | |
| A reaction: Almost every theory proposed by Lewis hangs on the meaning of the word 'close', as used here. If you visited twenty Earth-like worlds (watch Startrek?), it would be a struggle to decide their closeness to ours in rank order. |
| 6860 | How can one discriminate yellow from red, but not the colours in between? [Williamson] |
| Full Idea: If one takes a spectrum of colours from yellow to red, it might be that given a series of colour samples along that spectrum, each sample is indiscriminable by the naked eye from the next one, though samples at either end are blatantly different. | |
| From: Timothy Williamson (Interview with Baggini and Stangroom [2001], p.151) | |
| A reaction: This seems like a nice variant of the Sorites paradox (Idea 6008). One could demonstrate it with just three samples, where A and C seemed different from each other, but other comparisons didn't. |
| 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. |
| 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. |
| 8424 | Determinism says there can't be two identical worlds up to a time, with identical laws, which then differ [Lewis] |
| Full Idea: By determinism I mean that the prevailing laws of nature are such that there do not exist any two possible worlds which are exactly alike up to that time, which differ thereafter, and in which those laws are never violated. | |
| From: David Lewis (Causation [1973], p.196) | |
| A reaction: This would mean that the only way an action of free will could creep in would be if it accepted being a 'violation' of the laws of nature. Fans of free will would probably prefer to call it a 'natural' phenomenon. I'm with Lewis. |
| 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... |
| 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. |
| 8420 | A proposition is a set of possible worlds where it is true [Lewis] |
| Full Idea: I identify a proposition with the set of possible worlds where it is true. | |
| From: David Lewis (Causation [1973], p.193) | |
| A reaction: As it stands, I'm baffled by this. How can 'it is raining' be a set of possible worlds? I assume it expands to refer to the truth-conditions, among possibilities as well as actualities. 'It is raining' fits all worlds where it is raining. |
| 8405 | A theory of causation should explain why cause precedes effect, not take it for granted [Lewis, by Field,H] |
| Full Idea: Lewis thinks it is a major defect in a theory of causation that it builds in the condition that the time of the cause precede that of the effect: that cause precedes effect is something we ought to explain (which his counterfactual theory claims to do). | |
| From: report of David Lewis (Causation [1973]) by Hartry Field - Causation in a Physical World | |
| A reaction: My immediate reaction is that the chances of explaining such a thing are probably nil, and that we might as well just accept the direction of causation as a given. Even philosophers balk at the question 'why doesn't time go backwards?' |
| 8427 | I reject making the direction of causation axiomatic, since that takes too much for granted [Lewis] |
| Full Idea: One might stipulate that a cause must always precede its effect, but I reject this solution. It won't solve the problem of epiphenomena, it rejects a priori any backwards causation, and it trivializes defining time-direction through causation. | |
| From: David Lewis (Causation [1973], p.203) | |
| A reaction: [compressed] Not strong arguments, I would say. Maybe apparent causes are never epiphenomenal. Maybe backwards causation is impossible. Maybe we must use time to define causal direction, and not vice versa. |
| 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. |
| 10392 | It is just individious discrimination to pick out one cause and label it as 'the' cause [Lewis] |
| Full Idea: We sometimes single out one among all the causes of some event and call it 'the' cause. ..We may select the abnormal causes, or those under human control, or those we deem good or bad, or those we want to talk about. This is invidious discrimination. | |
| From: David Lewis (Causation [1973]) | |
| A reaction: This is the standard view expressed by Mill - presumably the obvious empiricist line. But if we specify 'the pre-conditions' for an event, we can't just mention ANY fact prior to the effect - there is obvious relevance. So why not for 'the' cause as well? |
| 8419 | The modern regularity view says a cause is a member of a minimal set of sufficient conditions [Lewis] |
| Full Idea: In present-day regularity analyses, a cause is defined (roughly) as any member of any minimal set of actual conditions that are jointly sufficient, given the laws, for the existence of the effect. | |
| From: David Lewis (Causation [1973], p.193) | |
| A reaction: This is the view Lewis is about to reject. It seem to summarise the essence of the Mackie INUS theory. This account would make the presence of oxygen a cause of almost every human event. |
| 8421 | Regularity analyses could make c an effect of e, or an epiphenomenon, or inefficacious, or pre-empted [Lewis] |
| Full Idea: In the regularity analysis of causes, instead of c causing e, c might turn out to be an effect of e, or an epiphenomenon, or an inefficacious effect of a genuine cause, or a pre-empted cause (by some other cause) of e. | |
| From: David Lewis (Causation [1973], p.194) | |
| A reaction: These are Lewis's reasons for rejecting the general regularity account, in favour of his own particular counterfactual account. It is unlikely that c would be regularly pre-empted or epiphenomenal. If we build time's direction in, it won't be an effect. |
| 17525 | The counterfactual view says causes are necessary (rather than sufficient) for their effects [Lewis, by Bird] |
| Full Idea: The Humean idea, developed by Lewis, is that rather than being sufficient for their effects, causes are (counterfactual) necessary for their effects. | |
| From: report of David Lewis (Causation [1973]) by Alexander Bird - Causation and the Manifestation of Powers p.162 |
| 17524 | Lewis has basic causation, counterfactuals, and a general ancestral (thus handling pre-emption) [Lewis, by Bird] |
| Full Idea: Lewis's basic account has a basic causal relation, counterfactual dependence, and the general causal relation is the ancestral of this basic one. ...This is motivated by counterfactual dependence failing to be general because of the pre-emption problem. | |
| From: report of David Lewis (Causation [1973]) by Alexander Bird - Causation and the Manifestation of Powers p.161 | |
| A reaction: It is so nice when you struggle for ages with a topic, and then some clever person summarises it clearly for you. |
| 8397 | Counterfactual causation implies all laws are causal, which they aren't [Tooley on Lewis] |
| Full Idea: Some counterfactuals are based on non-causal laws, such as Newton's Third Law of Motion. 'If no force one way, then no force the other'. Lewis's counterfactual analysis implies that one force causes the other, which is not the case. | |
| From: comment on David Lewis (Causation [1973]) by Michael Tooley - Causation and Supervenience 5.2 | |
| A reaction: So what exactly does 'cause' my punt to move forwards? Basing causal laws on counterfactual claims looks to me like putting the cart before the horse. |
| 8423 | My counterfactual analysis applies to particular cases, not generalisations [Lewis] |
| Full Idea: My (counterfactual) analysis is meant to apply to causation in particular cases; it is not an analysis of causal generalizations. Those presumably quantify over particulars, but it is hard to match natural language to the quantifiers. | |
| From: David Lewis (Causation [1973], p.195) | |
| A reaction: What authority could you have for asserting a counterfactual claim, if you only had one observation? Isn't the counterfactual claim the hallmark of a generalisation? For one case, 'if not-c, then not-e' is just a speculation. |
| 8426 | One event causes another iff there is a causal chain from first to second [Lewis] |
| Full Idea: One event is the cause of another iff there exists a causal chain leading from the first to the second. | |
| From: David Lewis (Causation [1973], p.200) | |
| A reaction: It will be necessary to both explain and identify a 'chain'. Some chains are extremely tenuous (Alexander could stop a barrel of beer). Go back a hundred years, and the cause of any present event is everything back then. |
| 4795 | Lewis's account of counterfactuals is fine if we know what a law of nature is, but it won't explain the latter [Cohen,LJ on Lewis] |
| Full Idea: Lewis can elucidate the logic of counterfactuals on the assumption that you are not at all puzzled about what a law of nature is. But if you are puzzled about this, it cannot contribute anything towards resolving your puzzlement. | |
| From: comment on David Lewis (Causation [1973]) by L. Jonathan Cohen - The Problem of Natural Laws p.219 | |
| A reaction: This seems like a penetrating remark. The counterfactual theory is wrong, partly because it is epistemological instead of ontological, and partly because it refuses to face the really difficult problem, of what is going on out there. |
| 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. |
| 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. |
| 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. |
