3 ideas
16458 | Semantic vagueness involves alternative and equal precisifications of the language [Lewis] |
Full Idea: If vagueness is semantic indeterminacy, then wherever we have vague statements, we have several alternative precisifications of the vague language involved, all with equal claims of being 'intended'. | |
From: David Lewis (Vague Identity: Evans misunderstood [1988], p.318) |
10494 | Several words may label a category; one word can name several categories; some categories lack words [Ellen] |
Full Idea: Words are not always a good guide to the existence of categories: there may be several words which label the same categories (synonyms). and the same word can be used for quite different ideas. Some categories may exist without being labelled. | |
From: Roy Ellen (Categories, Classification, Cogn. Anthropology [2006], I) | |
A reaction: This is the sort of point which seems obvious to anyone outside philosophy, but which philosophers seem to find difficult to accept. Philosophers should pay much more attention to animals, and to illiterate peoples. Varieties of rice can lack labels. |
16721 | Changes in secondary qualities are caused by changes in primary qualities [Giles of Orleans] |
Full Idea: Every alteration in secondary qualities is caused by some alteration made in the primary qualities. | |
From: Giles of Orleans (On 'Generation and Corruption' [1270], I.6c) | |
A reaction: Pasnau calls this the 'supervenience' thesis, here with the addition of causation. Was this doctrine retained by Locke and Boyle? |
