18711 | A proposition is any expression which can be significantly negated [Wittgenstein] |
Full Idea: Any affirmation can be negated: if it has sense to say p it also has sense to say ¬p. ...A proposition therefore is any expression which can be significantly negated. | |
From: Ludwig Wittgenstein (Lectures 1930-32 (student notes) [1931], B I.2) | |
A reaction: I'm not sure about 'therefore'. I'm thinking you would have to already grasp the proposition in order to apply his negation test. |
