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. |
18439 | Because things can share attributes, we cannot individuate attributes clearly [Quine] |
Full Idea: No two classes have exactly the same members, but two different attributes may be attributes of exactly the same things. Classes are identical when their members are identical. ...On the other hand, attributes have no clear principle of individuation. | |
From: Willard Quine (On the Individuation of Attributes [1975], p.100) |
18442 | You only know an attribute if you know what things have it [Quine] |
Full Idea: May we not say that you know an attribute only insofar as you know what things have it? | |
From: Willard Quine (On the Individuation of Attributes [1975], p.106) | |
A reaction: Simple, and the best defence of class nominalism (a very implausible theory) which I have encountered. Do I have to know all the things? Do I not know 'red' if I don't know tomatoes have it? |
18441 | No entity without identity (which requires a principle of individuation) [Quine] |
Full Idea: We have an acceptable notion of class, or physical object, or attribute, or any other sort of object, only insofar as we have an acceptable principle of individuation for that sort of object. There is no entity without identity. | |
From: Willard Quine (On the Individuation of Attributes [1975], p.102) | |
A reaction: Note that this is his criterion for an 'acceptable' notion. Presumably that is for science. It permits less acceptable notions which don't come up to the standard. And presumably true things can be said about the less acceptable entities. |
18440 | Identity of physical objects is just being coextensive [Quine] |
Full Idea: Physical objects are identical if and only if coextensive. | |
From: Willard Quine (On the Individuation of Attributes [1975], p.101) | |
A reaction: The supposed counterexample to this is the statue and the clay it is made of, which are said to have different modal properties (destroying the statue doesn't destroy the clay). |
4870 | The most beautiful hand seen through the microscope will appear horrible [Spinoza] |
Full Idea: The most beautiful hand seen through the microscope will appear horrible. | |
From: Baruch de Spinoza (Letters to Hugo Boxel [1674], 1674?) | |
A reaction: Spinoza offers this nicely expressed point to support his view that beauty is strictly relative to observers, but I am unconvinced. If the outline of the hand is its key aesthetic feature, the viewer through the microscope cannot see it. |
