22427 | To explain object qualities, primary qualities must be more than mere sources of experience [McGinn] |
Full Idea: In order that we have available an explanation of the qualities of objects we need to be able to conceive primary qualities as consisting in something other than powers to produce experiences. | |
From: Colin McGinn (Subjective View: sec qualities and indexicals [1983], 6 n 52) | |
A reaction: I suppose if the qualities are nothing more than the source of the experiences, that is Kant's noumenon. Nothing more could be said. The seems to be a requirement for tacit inference here. We infer the interior of the tomato. |
9559 | If a successful theory confirms mathematics, presumably a failed theory disconfirms it? [Chihara] |
Full Idea: If mathematics shares whatever confirmation accrues to the theories using it, would it not be reasonable to suppose that mathematics shares whatever disconfirmation accrues to the theories using it? | |
From: Charles Chihara (A Structural Account of Mathematics [2004], 05.8) | |
A reaction: Presumably Quine would bite the bullet here, although maths is much closer to the centre of his web of belief, and so far less likely to require adjustment. In practice, though, mathematics is not challenged whenever an experiment fails. |
9566 | No scientific explanation would collapse if mathematical objects were shown not to exist [Chihara] |
Full Idea: Evidently, no scientific explanations of specific phenomena would collapse as a result of any hypothetical discovery that no mathematical objects exist. | |
From: Charles Chihara (A Structural Account of Mathematics [2004], 09.1) | |
A reaction: It is inconceivable that anyone would challenge this claim. A good model seems to be drama; a play needs commitment from actors and audience, even when we know it is fiction. The point is that mathematics doesn't collapse either. |
