| 13745 | Supervenience is not a dependence relation, on the lines of causal, mereological or semantic dependence [Kim] |
| Full Idea: It is a mistake, or at least misleading, to think of supervenience itself as a special and distinctive type of dependence relation, alongside causal dependence, mereological dependence, semantic dependence, and others. | |
| From: Jaegwon Kim (Postscripts on supervenience [1993], 2) | |
| A reaction: The point, I take it, is that supervenience is something which requires explanation, rather than being a conclusion to the debate. Why are statues beautiful? Why do brains generate minds? |
| 13746 | Supervenience is just a 'surface' relation of pattern covariation, which still needs deeper explanation [Kim] |
| Full Idea: Supervenience itself is not an explanatory relation, not a 'deep' metaphysical relation; rather it is a 'surface' relation that reports a pattern of property covariation, suggesting the presence of an interesting dependency relation that might explain it. | |
| From: Jaegwon Kim (Postscripts on supervenience [1993], 2) | |
| A reaction: I think the underlying idea here is that supervenience appeals to the Humean view of physical laws as mere regularities, but it is no good for those who seek underlying mechanisms to explain the patterns and regularities. Humeans are wrong. |
| 14082 | No sortal could ever exactly pin down which set of particles count as this 'cup' [Schaffer,J] |
| Full Idea: Many decent candidates could the referent of this 'cup', differing over whether outlying particles are parts. No further sortal I could invoke will be selective enough to rule out all but one referent for it. | |
| From: Jonathan Schaffer (Deflationary Metaontology of Thomasson [2009], 3.1 n8) | |
| A reaction: I never had much faith in sortals for establishing individual identity, so this point comes as no surprise. The implication is strongly realist - that the cup has an identity which is permanently beyond our capacity to specify it. |
| 14081 | Identities can be true despite indeterminate reference, if true under all interpretations [Schaffer,J] |
| Full Idea: There can be determinately true identity claims despite indeterminate reference of the terms flanking the identity sign; these will be identity claims true under all admissible interpretations of the flanking terms. | |
| From: Jonathan Schaffer (Deflationary Metaontology of Thomasson [2009], 3.1) | |
| A reaction: In informal contexts there might be problems with the notion of what is 'admissible'. Is 'my least favourite physical object' admissible? |
| 7444 | Type-type psychophysical identity is combined with a functional characterisation of pain [Lewis] |
| Full Idea: The materialist theory Armstrong and I proposed joins claims of type-type psychophysical identity with a behaviourist or functionalist way of characterising mental states such as pain. | |
| From: David Lewis (Mad Pain and Martian Pain [1980], §III) | |
| A reaction: Armstrong has backed off from 'type-type' identity, because the realisations of a given mental state might be too diverse to be considered of the same type. Putnam's machine functionalism allows the possibility of dualism. |
| 7445 | The application of 'pain' to physical states is non-rigid and contingent [Lewis] |
| Full Idea: The word 'pain' is a non-rigid designator; it is a contingent matter what state the concept and the word apply to. (Note: so the sort of theory Kripke argues against is not what we propose). | |
| From: David Lewis (Mad Pain and Martian Pain [1980], §III) | |
| A reaction: I like the view that a given quale is necessarily identical to a given mental state, but that many mental states might occupy a given behavioural role. The smell of roses might occupy the behavioural role of pain. Frog pain isn't quite like ours. |
| 7443 | A theory must be mixed, to cover qualia without behaviour, and behaviour without qualia [Lewis, by PG] |
| Full Idea: To pass our test it seems that our theory will have to be a 'mixed' theory, to account for the Madman (whose pain has odd causes, and odd effects) and also for the Martian (who has normal causes and effects, but an odd physical state). | |
| From: report of David Lewis (Mad Pain and Martian Pain [1980], §II) by PG - Db (ideas) | |
| A reaction: A statement that 'pain' is ambiguous (qualia/causal role) would help a lot here. Martians have the causal role but no qualia, and the madman has the qualia but lacks the causal role. I say lots of different qualia might have the same causal role. |
