| 18005 | Philosophy aims to become more disciplined about categories [Ryle] |
| Full Idea: Philosophy is the replacement of category-habits by category-disciplines. | |
| From: Gilbert Ryle (The Concept of Mind [1949], Intro p.8), quoted by Ofra Magidor - Category Mistakes 1.2 | |
| A reaction: I rather like this. It fits the view the idea that metaphysics aims to give the structure of reality. If there are not reasonably uniform categories for things, then reality is indescribable. Improving our categories seems a thoroughly laudable aim. |
| 14297 | A dispositional property is not a state, but a liability to be in some state, given a condition [Ryle] |
| Full Idea: To possess a dispositional property is not to be in a particular state;..it is to be bound or liable to be in a particular state, or undergo a particular change, when a particular condition is realized. | |
| From: Gilbert Ryle (The Concept of Mind [1949], II (7)) | |
| A reaction: Whether this view is correct is the central question about dispositions. Ryle's view is tied in with Humean regularities and behaviourism about mind. The powers view, which I favour, says a disposition is a drawn bow, an actual state of power. |
| 14300 | No physical scientist now believes in an occult force-exerting agency [Ryle] |
| Full Idea: The old error treating the term 'Force' as denoting an occult force-exerting agency has been given up in the physical sciences. | |
| From: Gilbert Ryle (The Concept of Mind [1949], V (1)) | |
| A reaction: Since 1949 they seem to have made a revival, once they are divested of their religious connotations. The word 'agency' is the misleading bit. Even Leibniz's monads weren't actual agents - he always said that was 'an analogy'. |
| 11897 | A principle of individuation may pinpoint identity and distinctness, now and over time [Mackie,P] |
| Full Idea: One view of a principle of individuation is what is called a 'criterion of identity', determining answers to questions about identity and distinctness at a time and over time - a principle of distinction and persistence. | |
| From: Penelope Mackie (How Things Might Have Been [2006], 8.2) | |
| A reaction: Since the term 'Prime Minister' might do this job, presumably there could be a de dicto as well as a de re version of individuation. The distinctness consists of chairing cabinet meetings, rather than being of a particular sex. |
| 11898 | Individuation may include counterfactual possibilities, as well as identity and persistence [Mackie,P] |
| Full Idea: A second view of the principle of individuation includes criteria of distinction and persistence, but also determines the counterfactual possibilities for a thing. | |
| From: Penelope Mackie (How Things Might Have Been [2006], 8.5) | |
| A reaction: It would be a pretty comprehensive individuation which defined all the counterfactual truths about a thing, as well as its actual truths. This is where powers come in. We need to know a thing's powers, but not how they cash out counterfactually. |
| 11883 | A haecceity is the essential, simple, unanalysable property of being-this-thing [Mackie,P] |
| Full Idea: Socrates can be assigned a haecceity: an essential property of 'being Socrates' which (unlike the property of 'being identical with Socrates') may be regarded as what 'makes' its possessor Socrates in a non-trivial sense, but is simple and unanalysable. | |
| From: Penelope Mackie (How Things Might Have Been [2006], 2.2) | |
| A reaction: I don't accept that there is any such property as 'being Socrates' (or even 'being identical with Socrates'), except as empty locutions or logical devices. A haecceity seems to be the 'ultimate subject of predication', with no predicates of its own. |
| 11889 | Essentialism must avoid both reduplication of essences, and multiple occupancy by essences [Mackie,P] |
| Full Idea: The argument for unshareable properties (the Reduplication Argument) suggests the danger of reduplication of Berkeley; the argument for incompatible properties (Multiple Occupancy) says Berkeley and Hume could be in the same possible object. | |
| From: Penelope Mackie (How Things Might Have Been [2006], 2.8) | |
| A reaction: These are her arguments in favour of essential properties being necessarily incompatible between objects. Whatever the answer, it must allow essences for indistinguishables like electrons. 'Incompatible' points towards a haecceity. |
| 11877 | An individual essence is the properties the object could not exist without [Mackie,P] |
| Full Idea: By essentialism about individuals I simply mean the view that individual things have essential properties, where an essential property of an object is a property that the object could not have existed without. | |
| From: Penelope Mackie (How Things Might Have Been [2006], 1.1) | |
| A reaction: This presumably means I could exist without a large part of my reason and consciousness, but could not exist without one of my heart valves. This seems to miss the real point of essence. I couldn't exist without oxygen - not one of my properties. |
| 11882 | No other object can possibly have the same individual essence as some object [Mackie,P] |
| Full Idea: Individual essences are essential properties that are unique to them alone. ...If a set of properties is an individual essence of A, then A has the properties essentially, and no other actual or possible object actually or possibly has them. | |
| From: Penelope Mackie (How Things Might Have Been [2006], 2.1/2) | |
| A reaction: I'm unconvinced about this. Tigers have an essence, but individual tigers have individual essences over and above their tigerish qualities, yet the perfect identity of two tigers still seems to be possible. |
| 11886 | There are problems both with individual essences and without them [Mackie,P] |
| Full Idea: If all objects had individual essences, there would be no numerical difference without an essential difference. But if there aren't individual essences, there could be two things sharing all essential properties, differing only in accidental properties. | |
| From: Penelope Mackie (How Things Might Have Been [2006], 2.5) | |
| A reaction: Depends how you define individual essence. Why can't two electrons have the same individual essence. To postulate a 'kind essence' which bestows the properties on each electron is to get things the wrong way round. |
| 11909 | Unlike Hesperus=Phosophorus, water=H2O needs further premisses before it is necessary [Mackie,P] |
| Full Idea: There is a disanalogy between 'necessarily water=H2O' and 'necessarily Hesperus=Phosphorus'. The second just needs the necessity of identity, but the first needs 'x is a water sample' and 'x is an H2O' sample to coincide in all possible worlds. | |
| From: Penelope Mackie (How Things Might Have Been [2006], 10.1.) | |
| A reaction: This comment is mainly aimed at Kripke, who bases his essentialism on identities, rather than at Putnam. |
| 11899 | Why are any sortals essential, and why are only some of them essential? [Mackie,P] |
| Full Idea: Accounts of sortal essentialism do not give a satisfactory explanation of why any sortals should be essential sortals, or a satisfactory account of why some sortals should be essential while others are not. | |
| From: Penelope Mackie (How Things Might Have Been [2006], 8.6) | |
| A reaction: A theory is not wrong, just because it cannot give a 'satisfactory explanation' of every aspect of the subject. We might, though, ask why the theory isn't doing well in this area. |
| 11906 | The Kripke and Putnam view of kinds makes them explanatorily basic, but has modal implications [Mackie,P] |
| Full Idea: Kripke and Putnam chose for their typical essence of kinds, sets of properties that could be thought of as explanatorily basic. ..But the modal implications of their views go well beyond this. | |
| From: Penelope Mackie (How Things Might Have Been [2006], 10.1) | |
| A reaction: Cf. Idea 11905. The modal implications are that the explanatory essence is also necessary to the identity of the thing under discussion, such as H2O. So do basic explanations carry across into all possible worlds? |
| 11894 | Origin is not a necessity, it is just 'tenacious'; we keep it fixed in counterfactual discussions [Mackie,P] |
| Full Idea: I suggest 'tenacity of origin' rather than 'necessity of origin'. ..The most that we need is that Caesar's having something similar to his actual origin in certain respects (e.g. his actual parents) is normally kept fixed in counterfactual speculation. | |
| From: Penelope Mackie (How Things Might Have Been [2006], 6.9) | |
| A reaction: I find necessity or essentially of origin very unconvincing, so I rather like this. Origin is just a particularly stable way to establish our reference to something. An elusive spy may have little more than date and place of birth to fix them. |
| 11887 | Transworld identity without individual essences leads to 'bare identities' [Mackie,P] |
| Full Idea: Transworld identity without individual essences leads to 'bare identities'. | |
| From: Penelope Mackie (How Things Might Have Been [2006], 2.7) | |
| A reaction: [She gives an argument for this, based on Forbes] I certainly favour the notion of individual essences over the notion of bare identities. We must distinguish identity in reality from identity in concept. Identities are points in conceptual space. |
| 11890 | De re modality without bare identities or individual essence needs counterparts [Mackie,P] |
| Full Idea: Anyone who wishes to avoid both bare identities and individual essences, without abandoning de re modality entirely, must adopt counterpart theory. | |
| From: Penelope Mackie (How Things Might Have Been [2006], 4.1) | |
| A reaction: This at least means that Lewis's proposal has an important place in the discussion, forcing us to think more clearly about the identities involved when we talk of possibilities. Mackie herself votes for bare indentities. |
| 11892 | Things may only be counterparts under some particular relation [Mackie,P] |
| Full Idea: A may be a counterpart of B according to one counterpart relation (similarity of origin, say), but not according to another (similarity of later history). | |
| From: Penelope Mackie (How Things Might Have Been [2006], 5.3) | |
| A reaction: Hm. Would two very diverse things have to be counterparts because they were kept in the same cupboard in different worlds? Can the counterpart relationship diverge or converge over time? Yes, I presume. |
| 11893 | Possibilities for Caesar must be based on some phase of the real Caesar [Mackie,P] |
| Full Idea: I take the 'overlap requirement' for Julius Caesar to be that, when considering how he might have been different, you have to take him as he actually was at some time in his existence, and consider possibilities consistent with that. | |
| From: Penelope Mackie (How Things Might Have Been [2006], 6.5) | |
| A reaction: This is quite a large claim (larger than Mackie thinks?), as it seems equally applicable to properties, states of affairs and propositions, as well as to individuals. Possibility that has no contact at all with actuality is beyond our comprehension. |
| 11884 | The theory of 'haecceitism' does not need commitment to individual haecceities [Mackie,P] |
| Full Idea: The theory that things have 'haecceities' must be sharply distinguished from the theory referred to as 'haecceitism', which says there may be differences in transworld identities that do not supervene on qualitative differences. | |
| From: Penelope Mackie (How Things Might Have Been [2006], 2.2 n7) | |
| A reaction: She says later [p,43 n] that it is possible to be a haecceitist without believing in individual haecceities, if (say) the transworld identities had no basis at all. Note that if 'thisness' is 'haecceity', then 'whatness' is 'quiddity'. |
| 11905 | Locke's kind essences are explanatory, without being necessary to the kind [Mackie,P] |
| Full Idea: One might speak of 'Lockean real essences' of a natural kind, a set of properties that is basic in the explanation of the other properties of the kind, without commitment to the essence belonging to the kind in all possible worlds. | |
| From: Penelope Mackie (How Things Might Have Been [2006], 10.1) | |
| A reaction: I think this may be the most promising account. The essence of a tiger explains what tigers are like, but tigers may evolve into domestic pets. Questions of individuation and of explaining seem to be quite separate. |
| 2622 | Can one movement have a mental and physical cause? [Ryle] |
| Full Idea: The dogma of the Ghost in the Machine maintains that there exist both minds and bodies; that there are mechanical causes of corporeal movements, and mental causes of corporeal movements. | |
| From: Gilbert Ryle (The Concept of Mind [1949], I (3)) | |
| A reaction: This nicely identifies the problem of double causation, which can be found in Spinoza (Idea 4862). The dualists have certainly got a problem here, but they can deny a conflict. The initiation of a hand movement is not mechanical at all. |
| 1353 | Reporting on myself has the same problems as reporting on you [Ryle] |
| Full Idea: My reports on myself are subject to the same kinds of defects as are my reports on you. | |
| From: Gilbert Ryle (The Concept of Mind [1949], Ch.6) | |
| A reaction: This may be true of memories or of motives, but it hardly seems to apply to being in pain, where you might be totally lying, where the worst I could do to myself is exaggerate. "You're fine; how am I?" |
| 1354 | We cannot introspect states of anger or panic [Ryle] |
| Full Idea: No one could introspectively scrutinize the state of panic or fury. | |
| From: Gilbert Ryle (The Concept of Mind [1949], Ch.6) | |
| A reaction: It depends what you mean by 'scrutinize'. No human being ever loses their temper or panics without a background thought of "Oh dear, I'm losing it - it would probably be better if I didn't" (or, as Aristotle might say, "I'm angry, and so I should be"). |
| 2624 | I cannot prepare myself for the next thought I am going to think [Ryle] |
| Full Idea: One thing that I cannot prepare myself for is the next thought that I am going to think. | |
| From: Gilbert Ryle (The Concept of Mind [1949], VI (7)) |
| 2620 | Dualism is a category mistake [Ryle] |
| Full Idea: The official theory of mind (as private, non-spatial, outside physical laws) I call 'the dogma of the Ghost in the Machine'. I hope to prove it entirely false, and show that it is one big mistake, namely a 'category mistake'. | |
| From: Gilbert Ryle (The Concept of Mind [1949], I (2)) | |
| A reaction: This is the essence of Ryle's eliminitavist behaviourism. Personally I agree that the idea of a separate 'ghost' running the machine is utterly implausible, but it isn't a 'category mistake'. The mind clearly exists, but the confusion is about what it is. |
| 2388 | Behaviour depends on desires as well as beliefs [Chalmers on Ryle] |
| Full Idea: Another problem for Ryle (from Chisholm and Geach) is that no mental state could be defined by a single range of behavioural dispositions, independent of any other mental states. (Behaviour depends upon desires as well as beliefs). | |
| From: comment on Gilbert Ryle (The Concept of Mind [1949]) by David J.Chalmers - The Conscious Mind 1.1.2 | |
| A reaction: The defence of behaviourism is to concede this point, but suggest that behavioural dispositions come in large groups of interdependent sets, some relating to beliefs, others relating to desires, and each group leads to a behaviour. |
| 3354 | You can't explain mind as dispositions, if they aren't real [Benardete,JA on Ryle] |
| Full Idea: Ryle is tough-minded to the point of incoherence when he combines a dispositional account of the mind with an anti-realist account of dispositions. | |
| From: comment on Gilbert Ryle (The Concept of Mind [1949]) by José A. Benardete - Metaphysics: the logical approach Ch.22 | |
| A reaction: A nice point, but it strikes me that Ryle was, by temperament at least, an eliminativist about the mind, so the objection would not bother him. Maybe a disposition and a property are the same thing? |
| 2387 | How can behaviour be the cause of behaviour? [Chalmers on Ryle] |
| Full Idea: A problem for Ryle is that mental states may cause behaviour, but if mental states are themselves behavioural or behavioural dispositions, as opposed to internal states, then it is hard to see how they could do the job. | |
| From: comment on Gilbert Ryle (The Concept of Mind [1949]) by David J.Chalmers - The Conscious Mind 1.1.2 | |
| A reaction: I strongly approve of this, as an objection to any form of behaviourism or functionalism. If you identify something by its related behaviour, or its apparent function, this leaves the question 'WHY does it behave or function in this way?' |
| 23104 | Dworkin believed we should promote equality, to increase autonomy [Dworkin, by Kekes] |
| Full Idea: Egalitarians believe that most often it is by promoting equality that autonomy is increased; this is the egalitarianism of such liberals as Ronald Dworkin. | |
| From: report of Ronald Dworkin (Taking Rights Seriously [1977]) by John Kekes - Against Liberalism 05.1 | |
| A reaction: Not my idea of equality. The whole point is to ascribe reasonable equality to everyone, including those with a limited capacity for autonomy. Equality is a consequence of universal respect. |
| 23257 | We can treat people as equals, or actually treat them equally [Dworkin, by Grayling] |
| Full Idea: Dworkin distinguishes between treating people as equals, that is, 'with equal concern and respect', and treating them equally. This latter can be unjust. | |
| From: report of Ronald Dworkin (Taking Rights Seriously [1977]) by A.C. Grayling - The Good State 2 | |
| A reaction: The big difference I see between them is that the first is mere words, and the second is actions. Cf. 'thoughts and prayers' after US school shootings. How about equal entitlements, all things being equal? |
| 18621 | Treating people as equals is the one basic value of all plausible political theories [Dworkin, by Kymlicka] |
| Full Idea: Dworkin suggests that every plausible political theory has the same ultimate value, which is equality - in the more abstract and fundamental sense of treating people 'as equals'. | |
| From: report of Ronald Dworkin (Taking Rights Seriously [1977], 179-83) by Will Kymlicka - Contemporary Political Philosophy (1st edn) | |
| A reaction: I associate this idea with Kant (who says they are equal by virtue of their rationality), so that's a pretty influential idea. I would associate the main challenge to this with Nietzsche. |
| 11907 | Maybe the identity of kinds is necessary, but instances being of that kind is not [Mackie,P] |
| Full Idea: One could be an essentialist about natural kinds (of tigers, or water) while holding that every actual instance or sample of a natural kind is only accidentally an instance or a sample of that kind. | |
| From: Penelope Mackie (How Things Might Have Been [2006], 10.2) | |
| A reaction: You wonder, then, in what the necessity of the kind consists, if it is not rooted in the instances, and presumably it could only result from a stipulative definition, and hence be conventional. |
