1. Philosophy / G. Scientific Philosophy / 3. Scientism
All worthwhile philosophy is synthetic theorizing, evaluated by experience [Papineau]
     Full Idea: I would say that all worthwhile philosophy consists of synthetic theorizing, evaluated against experience.
     From: David Papineau (Philosophical Insignificance of A Priori Knowledge [2010], §1)
     A reaction: This is the view that philosophy is just science at a high level of abstraction, and he explicitly rejects 'conceptual analysis' as a fruitful activity. I need to take a stance on this one, but find I am in a state of paralysis. Welcome to philosophy...
3. Truth / A. Truth Problems / 4. Uses of Truth
Truth is what unites, and the profound truths create a community [Jaspers]
     Full Idea: Truth is what unites. ...[p.145] The most profound truth is that which all men might understand so as to form one community.
     From: Karl Jaspers (Philosophy [1932], vol.2)
     A reaction: Nice slogan, for robust realists like me. The hallmark of truth is our convergence on it. This is a 20th century existentialist perfectly expounding the enlightenment dream. The best rhetoric is truthful rhetoric.
7. Existence / D. Theories of Reality / 5. Naturalism
Externalism may be the key idea in philosophical naturalism [Papineau]
     Full Idea: Some people view an externalist approach to epistemology as the essence of philosophical naturalism.
     From: David Papineau (Philosophical Naturalism [1993], Intro)
     A reaction: I suspect philosophers avoid psychology and mental events, simply because they are elusive. Externalism is a theory about justification, and independent of naturalism as a metaphysic.
7. Existence / D. Theories of Reality / 11. Ontological Commitment / e. Ontological commitment problems
Our best theories may commit us to mathematical abstracta, but that doesn't justify the commitment [Papineau]
     Full Idea: Our empirically best-supported theories may commit us to certain abstract mathematical entities, but this does not necessarily mean that this is what justifies our commitment. That we are committed doesn't explain why we should be.
     From: David Papineau (Philosophical Insignificance of A Priori Knowledge [2010], §4)
     A reaction: A nice point. It is only a slightly gormless scientism which would say that we have to accept whatever scientists demand. Who's in charge here - scientists, mathematicians or philosophers? Don't answer that...
7. Existence / E. Categories / 1. Categories
All descriptive language is classificatory [Dupré]
     Full Idea: Classification pervades any descriptive use of language whatever.
     From: John Dupré (The Disorder of Things [1993], 1)
     A reaction: This is because, as Aristotle well knew, language consists almost entirely of universals (apart from the proper names). Language just is classification.
7. Existence / E. Categories / 2. Categorisation
We should aim for a classification which tells us as much as possible about the object [Dupré]
     Full Idea: The most important desideratum of a classificatory scheme is that assigning an object to a particular classification tell us as much as possible about that object.
     From: John Dupré (The Disorder of Things [1993], Ch 1)
     A reaction: We should probably say that the aim is a successful explanation, rather than a heap of information. If we are totally baffled by a particular type of object, it is presumably important to group the instances together, to focus the bafflement.
9. Objects / D. Essence of Objects / 8. Essence as Explanatory
Natural kinds don't need essentialism to be explanatory [Dupré]
     Full Idea: The importance of natural kinds for explanation does not depend on a doctrine of essences.
     From: John Dupré (The Disorder of Things [1993], 3)
     A reaction: He suggest as the alternative that laws do the explaining, employing natural kinds. He allows that individual essences might be explanatory.
9. Objects / D. Essence of Objects / 10. Essence as Species
A species might have its essential genetic mechanism replaced by a new one [Dupré]
     Full Idea: Contradicting one of the main points of essentialism, there is no reason in principle why a species should not survive the demise of its current genetic mechanisms (some other species coherence gradually taking over).
     From: John Dupré (The Disorder of Things [1993], 2)
     A reaction: I would say that this meant that the species had a new essence, because I don't take what is essential to be the same as what is necessary. The new genetics would replace the old as the basic explanation of the species.
It seems that species lack essential properties, so they can't be natural kinds [Dupré]
     Full Idea: It is widely agreed among biologists that no essential property can be found to demarcate species, so that if an essential property is necessary for a natural kind, species are not natural kinds.
     From: John Dupré (The Disorder of Things [1993], 2)
     A reaction: This uses 'essential' to mean 'necessary', but I would use 'essential' to mean 'deeply explanatory'. Biological species are, nevertheless, dubious members of an ontological system. Vegetables are the problem.
11. Knowledge Aims / A. Knowledge / 4. Belief / a. Beliefs
Belief truth-conditions are normal circumstances where the belief is supposed to occur [Papineau]
     Full Idea: The truth condition of the belief is the 'normal' circumstances in which, given the learning process, it is biologically supposed to be present.
     From: David Papineau (Reality and Representation [1987], p.67), quoted by Christopher Peacocke - A Study of Concepts 5.2
     A reaction: How do we account for a belief in ghosts in this story? The notion of 'normal' circumstances and what is 'biologically supposed' to happen don't seem very appropriate. This is the 'teleological' view of belief.
12. Knowledge Sources / A. A Priori Knowledge / 9. A Priori from Concepts
A priori knowledge is analytic - the structure of our concepts - and hence unimportant [Papineau]
     Full Idea: I am a fully paid up-naturalist, but I see no reason to deny that a priori knowledge is possible. My view is that a priori knowledge is unimportant (esp to philosophy). If there is a priori knowledge, it is analytic, true by the structure of our concepts.
     From: David Papineau (Philosophical Insignificance of A Priori Knowledge [2010], §1)
     A reaction: It is one thing to say it is the structure of our concepts, and another to infer that it is unimportant. I take the structure of our concepts to be a shadow cast by the structure of the world. E.g. the structure of numbers reveals the world.
12. Knowledge Sources / B. Perception / 7. Causal Perception
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.
12. Knowledge Sources / E. Direct Knowledge / 2. Intuition
Intuition and thought-experiments embody substantial information about the world [Papineau]
     Full Idea: Naturalists can allow for thought-experiments in philosophy. Intuitions play an important role, but only because they embody substantial information about the world.
     From: David Papineau (Philosophical Insignificance of A Priori Knowledge [2010], §3)
     A reaction: In this sense, intuitions are just memories which are too complex for us to articulate. They are not the intuitions of 'pure reason'. It is hard to connect the intuitive spotting of a proof with memories of the physical world.
14. Science / A. Basis of Science / 4. Prediction
The possibility of prediction rests on determinism [Dupré]
     Full Idea: Determinism is the metaphysical underlay of the possibility of prediction.
     From: John Dupré (The Disorder of Things [1993], Intro)
     A reaction: Not convinced. There might be micro-indeterminacies which iron out into macro-regularities.
15. Nature of Minds / A. Nature of Mind / 1. Mind / e. Questions about mind
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?
15. Nature of Minds / A. Nature of Mind / 3. Mental Causation
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!
15. Nature of Minds / A. Nature of Mind / 4. Other Minds / c. Knowing other minds
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.
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.
15. Nature of Minds / A. Nature of Mind / 8. Brain
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.
15. Nature of Minds / B. Features of Minds / 1. Consciousness / a. Consciousness
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.
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.
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'.
15. Nature of Minds / B. Features of Minds / 1. Consciousness / e. Cause of consciousness
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.
15. Nature of Minds / B. Features of Minds / 1. Consciousness / f. Higher-order thought
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?
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.
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?
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.
16. Persons / F. Free Will / 2. Sources of Free Will
Freedom needs knowledge, the possibility of arbitrariness, and law [Jaspers]
     Full Idea: Without knowledge there is no freedom ....and without an arbitrary act there is no freedom, ....and there is no freedom without law.
     From: Karl Jaspers (Philosophy [1932], vol.2)
     A reaction: He emphasises that an arbitrary act is not a free act, but it is a precondition for being free. The submission to law is active freedom. If you believe in education (and you should) you must believe that knowledge is liberating.
16. Persons / F. Free Will / 4. For Free Will
I am aware that freedom is possible, and the freedom is not in theory, but in seeking freedom [Jaspers]
     Full Idea: Either there is no freedom or it is in asking about it. But what makes me ask is an original will to be free, so my freedom is anticipated in the fact of asking. I cannot prove it first, then will it. I will it because I am conscious of its possibility.
     From: Karl Jaspers (Philosophy [1932], vol.2)
     A reaction: This presents the subjective claims for free will rather more persuasively than usual. I am conscious of a possibility that I might flap my arms and fly, so that doesn't establish anything. But yearning to be free is a sort of freedom.
17. Mind and Body / A. Mind-Body Dualism / 6. Epiphenomenalism
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.
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?
17. Mind and Body / A. Mind-Body Dualism / 8. Dualism of Mind Critique
How does a dualist mind represent, exist outside space, and be transparent to itself? [Papineau]
     Full Idea: Even dualists must explain how the mind represents things, but then their mind-stuff has so many special powers already (being outside space but in time, being transparent to itself etc.) that one more scarcely seems worth worrying about.
     From: David Papineau (Philosophical Naturalism [1993], 3.1 n1)
     A reaction: I share the exasperation. It is hard to see how a dualist could even begin to formulate a theory about HOW the mind does so many different things. Could Descartes get a research grant for it? Would we understand God if he tried to explain it to us?
17. Mind and Body / C. Functionalism / 8. Functionalism critique
Functionalism needs causation and intentionality to explain actions [Papineau]
     Full Idea: The functionalist approach to the mind needs to invoke assumptions about what desires are for and beliefs are about, in order to infer what agents will do.
     From: David Papineau (Philosophical Naturalism [1993], 3.2)
     A reaction: Isn't the idea that you discover what desires are for and what beliefs are about by examining their function, and what the agent does? Which end should we start?
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.
17. Mind and Body / D. Property Dualism / 2. Anomalous Monism
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'.
17. Mind and Body / D. Property Dualism / 5. Supervenience of mind
Epiphenomenalism is supervenience without physicalism [Papineau]
     Full Idea: Supervenience is a necessary condition for physicalism, but it is not sufficient. Epiphenomenalism rules out mental variation without physical variation, but says mental properties are quite distinct from physical properties.
     From: David Papineau (Philosophical Naturalism [1993], 1.2)
     A reaction: I take full epiphenomenalism about mind to be incoherent, and not worth even mentioning (see Idea 7379). Papineau seems to be thinking of so-called property dualism (which may also be incoherent!).
Supervenience requires all mental events to have physical effects [Papineau]
     Full Idea: The argument for supervenience rests on the principle that any mental difference must be capable of showing itself in differential physical consequences.
     From: David Papineau (Philosophical Naturalism [1993], 1.8)
     A reaction: With our current knowledge of the brain, to assume anything less than this sort of correlation would be crazy.
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.
17. Mind and Body / E. Mind as Physical / 1. Physical Mind
Knowing what it is like to be something only involves being (physically) that thing [Papineau]
     Full Idea: Physicalism does not deny that there are conscious experiences, nor that 'it is like something to have them'. The claim is only that this is nothing different from what it is to be a physical system of the relevant kind.
     From: David Papineau (Philosophical Naturalism [1993], 4.2)
     A reaction: The implication is that no physicalist is an extreme eliminativist about consciousness, which seems to be correct. We all concede that weather exists, but have a reductive view of it. The key question is whether mind is reducible to physics.
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?
17. Mind and Body / E. Mind as Physical / 2. Reduction of Mind
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.
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.
17. Mind and Body / E. Mind as Physical / 5. Causal Argument
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.
17. Mind and Body / E. Mind as Physical / 6. Conceptual Dualism
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.
17. Mind and Body / E. Mind as Physical / 7. Anti-Physicalism / b. Multiple realisability
If a mental state is multiply realisable, why does it lead to similar behaviour? [Papineau]
     Full Idea: If functionalism implies that there is nothing physically in common among the realisations of a given mental state, then there is no possibility of any uniform explanation of why they all give rise to a common physical result.
     From: David Papineau (Philosophical Naturalism [1993], 2.2)
     A reaction: This is the well known interaction problem for dualism. The standard reply is to accept interaction as a given (with no apparent explanation). A miracle, if you like.
17. Mind and Body / E. Mind as Physical / 7. Anti-Physicalism / c. Knowledge argument
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.
18. Thought / A. Modes of Thought / 1. Thought
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.
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...
18. Thought / B. Mechanics of Thought / 5. Mental Files
There is a single file per object, memorised, reactivated, consolidated and expanded [Papineau, by Recanati]
     Full Idea: For Papineau there is just one file, which is initialised on the first encounter with the object, stored in memory, reactivated on further encounters, and consolidated with familiarity. Accumulation of information shows it is the same file.
     From: report of David Papineau (Phenomenal and Perceptual Concepts [2006]) by François Recanati - Mental Files 7.2
     A reaction: Recanati attempts to refute this view, defending a more complex taxonomy of files. I'm sympathetic to Papineau, as distinct shift in file type doesn't sound very plausible. Simplicity suggests Papineau as a better starting-point.
18. Thought / C. Content / 5. Twin Earth
Presumably molecular structure seems important because we never have the Twin Earth experience [Dupré]
     Full Idea: It is surely the absence of experiences like the one Putnam describes that makes it reasonable to attach to molecular structure at least most of the importance that Putnam ascribes to it.
     From: John Dupré (The Disorder of Things [1993], 1)
     A reaction: That is, whenever we experience water-like stuff, it always turns out to have the same molecular structure. Twin Earth is a nice thought experiment, except that XZY is virtually inconceivable.
18. Thought / C. Content / 6. Broad Content
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!
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.
19. Language / A. Nature of Meaning / 5. Meaning as Verification
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.
Verificationism about concepts means you can't deny a theory, because you can't have the concept [Papineau]
     Full Idea: Verificationism about concepts implies that thinkers will not share concepts with adherents of theories they reject. Those who reject the phlogiston theory will not possess the same concept as adherents, so cannot say 'there is no phlogiston'.
     From: David Papineau (Philosophical Insignificance of A Priori Knowledge [2010], §6)
     A reaction: The point seems to be more general - that it is hard to see how you can have a concept of anything which doesn't actually exist, if the concept is meant to rest on some sort of empirical verification.
19. Language / C. Assigning Meanings / 2. Semantics
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.
19. Language / C. Assigning Meanings / 8. Possible Worlds Semantics
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.
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.
19. Language / F. Communication / 4. Private Language
The Private Language argument only means people may misjudge their experiences [Papineau]
     Full Idea: I take the moral of the Private Language argument to be that there must be room for error in people's judgements about their experiences, not that those judgements must necessarily be expressed in a language used by a community.
     From: David Papineau (Philosophical Naturalism [1993], 4.4 n10)
     A reaction: These two readings don't seem to be in conflict, and the argument must have something to say about the communal nature of thought expressed in language. Language imposes introspection on us?
20. Action / C. Motives for Action / 4. Responsibility for Actions
My freedom increases as I broaden my vision of possiblities and motives [Jaspers]
     Full Idea: I become free by incessantly broadening my worldly orientation, by limitlessly visualising premises and possibilities of action, and by allowing all motives to speak to me. ...The more the totality determines my vision the freer I know I am.
     From: Karl Jaspers (Philosophy [1932], vol.2)
     A reaction: This matches my naturalistic view of responsibility for actions, which are those performed by the 'full' and knowing self. I note that freedom comes in degrees for him, so he presumably don't believe in absolute freedom. It is wholly subjective.
23. Ethics / F. Existentialism / 1. Existentialism
My helplessness in philosophising reveals my being, and begins its upsurge [Jaspers]
     Full Idea: Philosophising, not knowing, brings me to myself. The helplessness to which philosophising reduces me when I doubt its origin is an expressions of the helplessness of my self-being, and the reality of philosophising is the incipient upsurge of that being.
     From: Karl Jaspers (Philosophy [1932], vol.2)
     A reaction: I like the sound of 'philosophy as a way of life', and loosely aspire to it, but I'm still not sure what it means, other than a good way to pass the time. The idea that it leads to higher modes of being sounds a bit arrogant. But it is a good thing!
The struggle for Existenz is between people who are equals, and are utterly honest [Jaspers]
     Full Idea: The struggle for Existenz has to do with ...with utter candour, with the elimination of all kinds of power and superiority, with the other's self-being as well as with my own.
     From: Karl Jaspers (Philosophy [1932], vol.2)
     A reaction: This is reminiscent of Aristotle's conclusion that democracy is the society which is most conducive to true friendship. I like Jaspers's idea that existential enquiry is a team game.
Once we grasp freedom 'from' things, then freedom 'for' things becomes urgent [Jaspers]
     Full Idea: Once the question of 'freedom from what?' has been answered by shattering all objectivities, the question of 'freedom for what?' becomes all the more urgent.
     From: Karl Jaspers (Philosophy [1932], vol.2)
     A reaction: A quintessential existentialist idea, and its most appealing aspect. Message to all teenagers: don't get bogged down in what you are prevented from doing, but focus on what you can do. The first problem will melt away. (Unless you are in handcuffs....).
23. Ethics / F. Existentialism / 6. Authentic Self
Mundane existence is general, falling under universals, but Existens is unique to individuals [Jaspers]
     Full Idea: Mundane being, the being we know, is general because it is generally valid for everyone. ...Existenz is never general, and thus not a case that might be subsumed as particular under a universal.
     From: Karl Jaspers (Philosophy [1932], vol.2)
     A reaction: I'm trying to visualise a mode of existence which would fulfil only me, answering to my unique nature, but it looks like a vain delusion. I may be a one-off combination, but I see all of my ingredients in various other people.
'Existenz' is the potential being, which I could have, and ought to have [Jaspers]
     Full Idea: There is the being which in the phenomenality of existence is not but can be, ought to be, and therefore decides in time whether it is in eternity. This being is myself as 'Existenz'.
     From: Karl Jaspers (Philosophy [1932], vol.2)
     A reaction: This is quintessentially existentialist, in its claim that my mode of being could be quite other than it is. Personally I aim to fulfil the being I've got. Play the cards you have been dealt.
We want the correct grasp on being that is neither solipsism nor absorption in the crowd [Jaspers]
     Full Idea: We want our philosophising to illuminate the free, original, communicative grasp on being that will let us meet the constant threat of solipsism or universalism in existence.
     From: Karl Jaspers (Philosophy [1932], vol.2)
     A reaction: This sounds like the political wing of existentialism: the aim to get the right relationship between citizens - not too withdrawn, and not swallowed in the crowd. Liberal democracy, I should think.
23. Ethics / F. Existentialism / 7. Existential Action
Every decision I make moves towards or away from fulfilled Existenz [Jaspers]
     Full Idea: My Existenz, as a possibility, takes a step toward being or away from being, toward nothingness, in every choice or decision I make.
     From: Karl Jaspers (Philosophy [1932], vol.2)
     A reaction: The existential idea of action involves what you are, as well as what you do. There seems to be a paradox. My being is plastic, and can change enormously, so I should take responsibility for the change. But who is in charge of the changes?
26. Natural Theory / B. Natural Kinds / 1. Natural Kinds
Phylogenetics involves history, and cladism rests species on splits in lineage [Dupré]
     Full Idea: The phylogenetic conception of classification reflects the facts of evolutionary history. Cladism insists that every taxonomic distinction should reflect an evolutionary event of lineage bifurcation.
     From: John Dupré (The Disorder of Things [1993], 1)
     A reaction: Devitt attacks cladism nicely. It rules out species change without bifurcation, and it insists on species change even in a line which remains unchanged after a split.
Kinds don't do anything (including evolve) because they are abstract [Dupré]
     Full Idea: A kind, being an abstract object, cannot do anything, including evolve.
     From: John Dupré (The Disorder of Things [1993], 2)
     A reaction: Maybe. We might have an extensional view of the kind, so that 'gold' is the set of extant gold atoms. But possible gold atoms are also gold, and defunct ones too. Virtually every word in English is abtract if you think about it long enough.
26. Natural Theory / B. Natural Kinds / 7. Critique of Kinds
Natural kinds are decided entirely by the intentions of our classification [Dupré]
     Full Idea: The question of which natural kind a thing belongs to ....can be answered only in relation to some specification of the goal underlying the intent to classify the object.
     From: John Dupré (The Disorder of Things [1993], Intro)
     A reaction: I don't think I believe this. The situation is complex, and our intents are relevant, but to find an intent which no longer classifies tigers into the same category is wilful silliness.
Borders between species are much less clear in vegetables than among animals [Dupré]
     Full Idea: The richest source of illustrations is the vegetable kingdom, where specific differences tend to be much less clear than among animals, and considerable developmental plasticity is the rule.
     From: John Dupré (The Disorder of Things [1993], 1)
     A reaction: Nice. Just as the idea that laws of nature are mathematical suits physics, but founders on biology, so natural kinds founder in an area of biology to which we pay less attention. He cites prickly pears and lilies. I'm thinking oranges, satsumas etc.
Even atoms of an element differ, in the energy levels of their electrons [Dupré]
     Full Idea: Even if we claim that it is really isotopes not atoms that are the natural kinds (thus divorcing chemistry from ordinary language), atoms are said to differ with respect to such features as energy levels of the electrons.
     From: John Dupré (The Disorder of Things [1993], 2)
     A reaction: So we can't just pick out the features of one atom, and say that is the essence. Essence always involves some selection. I say the essence arises from the explanation of the atom's behaviour.
Ecologists favour classifying by niche, even though that can clash with genealogy [Dupré]
     Full Idea: To the extent that the occupants of a particular niche do not coincide with the members of a particular genealogical line, a possibility widely acknowledged to occur, ecologists must favour a method of classification lacking genealogical grounding.
     From: John Dupré (The Disorder of Things [1993], 2)
     A reaction: Zoo keepers probably classify by cages, or which zoo owns what, but that doesn't mean that they reject genealogy. Don't assume ecologists are rejecting any underlying classification that differs from theirs. Compare classification by economists.
Cooks, unlike scientists, distinguish garlic from onions [Dupré]
     Full Idea: It would be a severe culinary misfortune if no distinction were drawn between garlic and onions, a distinction that is not reflected in scientific taxonomy.
     From: John Dupré (The Disorder of Things [1993], 1)
     A reaction: Not every persuasive. We distinguish some cows from others because they taste better, but no one thinks that is a serious way in which to classify cows.
Wales may count as fish [Dupré]
     Full Idea: The claim that whales are not fish is a debatable one
     From: John Dupré (The Disorder of Things [1993], 1)
     A reaction: A very nice challenge to an almost unquestioned orthodoxy.
26. Natural Theory / C. Causation / 8. Particular Causation / b. Causal relata
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.
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.
26. Natural Theory / D. Laws of Nature / 10. Closure of Physics
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.
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.
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.
27. Natural Reality / A. Classical Physics / 2. Thermodynamics / c. Conservation of energy
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.
27. Natural Reality / G. Biology / 5. Species
Species are the lowest-level classification in biology [Dupré]
     Full Idea: Species are, by definition, the lowest-level classificatory unit, or basal taxonomic unit, for biological organisms.
     From: John Dupré (The Disorder of Things [1993], 2)
     A reaction: I think this is the 'infima species' for Aristotelians. What about 'male' and 'female' in each species?
The theory of evolution is mainly about species [Dupré]
     Full Idea: Species are what the theory of evolution is centrally about.
     From: John Dupré (The Disorder of Things [1993], 2)
