3626 | Knowing the attributes is enough to reveal a substance [Descartes] |
Full Idea: I have never thought that anything more is required to reveal a substance than its various attributes. | |
From: René Descartes (Reply to Fifth Objections [1641], 360) |
15537 | If cats are vague, we deny that the many cats are one, or deny that the one cat is many [Lewis] |
Full Idea: To deny that there are many cats on the mat (because removal of a few hairs seems to produce a new one), we must either deny that the many are cats, or else deny that the cats are many. ...I think both alternatives lead to successful solutions. | |
From: David Lewis (Many, but almost one [1993], 'The paradox') | |
A reaction: He credits the problem to Geach (and Tibbles), and says it is the same as Unger's 'problem of the many' (Idea 15536). |
15536 | We have one cloud, but many possible boundaries and aggregates for it [Lewis] |
Full Idea: Many surfaces are equally good candidates to be boundaries of a cloud; therefore many aggregates of droplets are equally good candidates to be the cloud. How is it that we have just one cloud? And yet we do. This is Unger's (1980) 'problem of the many'. | |
From: David Lewis (Many, but almost one [1993], 'The problem') | |
A reaction: This is the problem of vague objects, as opposed to the problem of vague predicates, or the problem of vague truths, or the problem of vague prepositions (like 'towards'). |
