15520 | Existence doesn't come in degrees; once asserted, it can't then be qualified [Lewis] |
Full Idea: Existence cannot be a matter of degree. If you say there is something that exists to a diminished degree, once you've said 'there is' your game is up. | |
From: David Lewis (Parts of Classes [1991], 3.5) | |
A reaction: You might have thought that this was so obvious as to be not worth saying, but as far as I can see it is a minority view in contemporary philosophy. It was Quine's view, and it is mine. |
18899 | Frege takes the existence of horses to be part of their concept [Frege, by Sommers] |
Full Idea: Frege regarded the existence of horses as a property of the concept 'horse'. | |
From: report of Gottlob Frege (Function and Concept [1891]) by Fred Sommers - Intellectual Autobiography 'Realism' |
15504 | Atomless gunk is an individual whose parts all have further proper parts [Lewis] |
Full Idea: A blob can represent atomless gunk: an individual whose parts all have further proper parts. | |
From: David Lewis (Parts of Classes [1991], 1.8) | |
A reaction: This is not the same as 'stuff', since gunk is a precise fusion of all those parts, whereas there is no such precision about stuff. Stuff is neutral as to whether it has atoms, or is endlessly divisible. My love of stuff grows. Laycock is a hero. |
15501 | We have no idea of a third sort of thing, that isn't an individual, a class, or their mixture [Lewis] |
Full Idea: As yet we have no idea of any third sort of thing that is neither individual nor class nor mixture of the two. | |
From: David Lewis (Parts of Classes [1991], 1.2) | |
A reaction: You can see that Lewis was a pupil of Quine. I quote this to show how little impression 'stuff' makes on the modern radar. His defence is that stuff may not be a 'thing', but then he seems to think that 'things' exhaust reality (top p.8 and 9). |
