13128 | 'Ultimate sortals' cannot explain ontological categories [Westerhoff on Wiggins] |
Full Idea: 'Ultimate sortals' are said to be non-subordinated, disjoint from one another, and uniquely paired with each object. Because of this, the ultimate sortal cannot be a satisfactory explication of the notion of an ontological category. | |
From: comment on David Wiggins (Identity and Spatio-Temporal Continuity [1971], p.75) by Jan Westerhoff - Ontological Categories §26 | |
A reaction: My strong intuitions are that Wiggins is plain wrong, and Westerhoff gives the most promising reasons for my intuition. The simplest point is that objects can obviously belong to more than one category. |
14064 | If a statue is identical with the clay of which it is made, that identity is contingent [Gibbard] |
Full Idea: Under certain conditions a clay statue is identical with the piece of clay of which it is made, and if this is so then the identity is contingent. | |
From: Allan Gibbard (Contingent Identity [1975], Intro) | |
A reaction: This initiated the modern debate about statues, and it is an attack on Kripke's claim that if two things are identical, then they are necessarily identical. Kripke seems right about Hesperus and Phosphorus, but not about the statue. |
14066 | A 'piece' of clay begins when its parts stick together, separately from other clay [Gibbard] |
Full Idea: A 'piece' of clay is a portion of clay which comes into existence when all of its parts come to be stuck to each other, and cease to be stuck to any clay which is not a part of the portion. | |
From: Allan Gibbard (Contingent Identity [1975], I) | |
A reaction: The sort of gormlessly elementary things that philosophers find themselves having to say, but this is a good basic assertion for a discussion of statue and clay, and I can't think of an objection to it. |
14067 | Clay and statue are two objects, which can be named and reasoned about [Gibbard] |
Full Idea: The piece of clay and the statue are 'objects' - that is to say, they can be designated with proper names, and the logic we ordinarily use will still apply. | |
From: Allan Gibbard (Contingent Identity [1975], I) | |
A reaction: An interesting indication of the way that 'object' is used in modern analytic philosophy, which may not be the way that it is used in ordinary English. The number 'seven', for example, seems to be an object by this criterion. |
14069 | We can only investigate the identity once we have designated it as 'statue' or as 'clay' [Gibbard] |
Full Idea: To ask meaningfully what that thing would be, we must designate it either as a statue or as a piece of clay. What that thing would be, apart from the way it is designated, is a question without meaning. | |
From: Allan Gibbard (Contingent Identity [1975], III) | |
A reaction: He obviously has a powerful point, but to suggest that we can only investigate a mysterious object once we have designated it as something sounds daft. It would ruin the fun of archaeology. |
14076 | Essentialism is the existence of a definite answer as to whether an entity fulfils a condition [Gibbard] |
Full Idea: Essentialism for a class of entities is that for one entity and a condition which it fulfills, the question of whether it necessarily fulfills the condition has a definite answer apart from the way the entity is specified. | |
From: Allan Gibbard (Contingent Identity [1975], VII) | |
A reaction: Yet another definition of essentialism, but resting, as usual in modern discussions, entirely on the notion of necessity. Kit Fine's challenge is that if you investigate the source of the necessity, it turns out to be an essence. |
14077 | Essentialism for concreta is false, since they can come apart under two concepts [Gibbard] |
Full Idea: Essentialism for the class of concrete things is false, since a statue necessarily fulfils a condition as 'Goliath', but only contingently fulfils it as 'lumpl'. On the other hand, essentialism for the class of individual concepts can be true. | |
From: Allan Gibbard (Contingent Identity [1975], VII) | |
A reaction: This rests on his definition of essentialism in Idea 14076. He rests his essentialism about concepts on an account given by Carnap ('Meaning and Necessity' §41). The essence of a statue and the essence of a lump of clay do seem distinct. |
14070 | A particular statue has sortal persistence conditions, so its origin defines it [Gibbard] |
Full Idea: A proper name like 'Goliath' denotes a thing in the actual world, and invokes a sortal with certain persistence criteria. Hence its origin makes a statue the statue that it is, and if statues in different worlds have the same beginning, they are the same. | |
From: Allan Gibbard (Contingent Identity [1975], III) | |
A reaction: Too neat. There are vague, ambiguous and duplicated origins. Persistence criteria can shift during the existence of a thing (like a club which changes its own constitution). In replicated statues, what is the status of the mould? |
14073 | Claims on contingent identity seem to violate Leibniz's Law [Gibbard] |
Full Idea: The most prominent objection to contingent identity (as in the case of the statue and its clay) is that it violates Leibniz's Law. | |
From: Allan Gibbard (Contingent Identity [1975], V) | |
A reaction: Depends what you mean by a property. The trickiest one would be that the statue has (right now) a disposition to be worth a lot, but the clay doesn't. But I don't think that is really a property of the statue. Properties are a muddle. |
14065 | Two identical things must share properties - including creation and destruction times [Gibbard] |
Full Idea: For two things to be strictly identical, they must have all properties in common. That means, among other things, that they must start to exist at the same time and cease to exist at the same time. | |
From: Allan Gibbard (Contingent Identity [1975], I) | |
A reaction: I don't accept that coming into existence at time t is a 'property' of a thing. Coincident objects give you the notion of 'existing as' something, which complicates the whole story. |
14074 | Leibniz's Law isn't just about substitutivity, because it must involve properties and relations [Gibbard] |
Full Idea: As a general law of substitutivity of identicals, Leibniz's Law is false. It is a law about properties and relations, that if two things are identical, they have the same properties and relations. It only works in contexts which attribute those. | |
From: Allan Gibbard (Contingent Identity [1975], V) | |
A reaction: I'm not convinced about relations, which are not intrinsic properties. Under different descriptions, the relations to human minds might differ. |
14072 | Possible worlds identity needs a sortal [Gibbard] |
Full Idea: Identity across possible worlds makes sense only with respect to a sortal | |
From: Allan Gibbard (Contingent Identity [1975], IV) | |
A reaction: See Gibbard's other ideas from this paper. I fear that the sortal invoked is too uncertain and slippery to do any useful job, and I can't see any principled difficulty with naming something before you can think of a sortal for it. |
14078 | Only concepts, not individuals, can be the same across possible worlds [Gibbard] |
Full Idea: It is meaningless to talk of the same concrete thing in different possible worlds, ...but it makes sense to speak of the same individual concept, which is just a function which assigns to each possible world in a set an individual in that world. | |
From: Allan Gibbard (Contingent Identity [1975], VII) | |
A reaction: A lovely bold response to the problem of transworld identity, but one which needs investigation. It sounds very promising to me. 'Aristotle' is a cocept, not a name. There is no separate category of 'names'. Wow. (Attach dispositions to concepts?). |
14079 | Kripke's semantics needs lots of intuitions about which properties are essential [Gibbard] |
Full Idea: To use Kripke's semantics, one needs extensive intuitions that certain properties are essential and others accidental. | |
From: Allan Gibbard (Contingent Identity [1975], X) | |
A reaction: As usual, we could substitute the word 'necessary' for 'essential' without changing his meaning. If we are always referring to 'our' Hubert Humphrey is speculations about him, then nearly all of his properties will be necessary ones. |
21833 | Research suggest that we overrate conscious experience [Flanagan] |
Full Idea: The emerging consensus is that we probably overrate the power of conscious experience in our lives. Freud, of course, said the same thing for different reasons. | |
From: Owen Flanagan (The Really Hard Problem [2007], 3 'Ontology') | |
A reaction: [He cites Pockett, Banks and Gallagher 2006]. Freud was concerned with big deep secrets, but the modern view concerns ordinary decisions and perceptions. An important idea, which should incline us all to become Nietzscheans. |
21834 | Sensations may be identical to brain events, but complex mental events don't seem to be [Flanagan] |
Full Idea: There is still some hope for something like identity theory for sensations. But almost no one believes that strict identity theory will work for more complex mental states. Strict identity is stronger than type neurophysicalism. | |
From: Owen Flanagan (The Really Hard Problem [2007], 3 'Ontology') | |
A reaction: It is so hard to express the problem. What needs to be explained? How can one bunch of neurons represent many different things? It's not like computing. That just transfers the data to brains, where the puzzling stuff happens. |
14071 | Naming a thing in the actual world also invokes some persistence criteria [Gibbard] |
Full Idea: The reference of a name in the actual world is fixed partly by invoking a set of persistence criteria which determine what thing it names. | |
From: Allan Gibbard (Contingent Identity [1975], III) | |
A reaction: This is offered as a modification to Kripke, to deal with the statue and clay. I fear that the 'persistence criteria' may be too vague, and too subject to possible change after the origin, to do the job required. |
21837 | Morality is normative because it identifies best practices among the normal practices [Flanagan] |
Full Idea: Morality is 'normative' in the sense that it consists of the extraction of ''good' or 'excellent' practices from common practices. | |
From: Owen Flanagan (The Really Hard Problem [2007], 4 'Naturalism') |
21830 | For Darwinians, altruism is either contracts or genetics [Flanagan] |
Full Idea: Two explanations came forward in the neo-Darwinian synthesis. Altruism is either 1) person-based reciprocal altruism, or 2) gene-based kin altruism. | |
From: Owen Flanagan (The Really Hard Problem [2007], 2 'Darwin') | |
A reaction: Flanagan obviously thinks there is also 'genuine psychological atruism'. Presumably we don't explain mathematics or music or the desire to travel as either contracts or genetics, so we have other explanations available. |
21835 | We need Eudaimonics - the empirical study of how we should flourish [Flanagan] |
Full Idea: It would be nice if I could advance the case for Eudaimonics - empirical enquiry into the nature, causes, and constituents of flourishing, …and the case for some ways of living and being as better than others. | |
From: Owen Flanagan (The Really Hard Problem [2007], 4 'Normative') | |
A reaction: Things seem to be moving in that direction. Lots of statistics about happiness have been appearing. |
21831 | Alienation is not finding what one wants, or being unable to achieve it [Flanagan] |
Full Idea: What Marx called 'alienation' is the widespread condition of not being able to discover what one wants, or not being remotely positioned to achieve. | |
From: Owen Flanagan (The Really Hard Problem [2007], 2 'Expanding') | |
A reaction: I took alienation to concern people's relationship to the means of production in their trade. On Flanagan's definition I would expect almost everyone aged under 20 to count as alienated. |
21832 | Buddhists reject God and the self, and accept suffering as key, and liberation through wisdom [Flanagan] |
Full Idea: Buddhism rejected the idea of a creator God, and the unchanging self [atman]. They accept the appearance-reality distinction, reward for virtue [karma], suffering defining our predicament, and that liberation [nirvana] is possible through wisdom. | |
From: Owen Flanagan (The Really Hard Problem [2007], 3 'Buddhism') | |
A reaction: [Compressed] Flanagan is an analytic philosopher and a practising Buddhist. Looking at a happiness map today which shows Europeans largely happy, and Africans largely miserable, I can see why they thought suffering was basic. |
