| 24102 | Thoughts are signs (just as words are) [Nietzsche] |
| Full Idea: Thoughts are merely signs, as words are signs for thoughts. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1881-82 [1882], 5[1]272) | |
| A reaction: The obvious question he invites is 'signs of what?'. His point must be that most thinking is both non-verbal and non-conscious, which he took to be true even of intellectual thought. I sympathise with his view. |
| 13475 | The Fregean concept of GREEN is a function assigning true to green things, and false to the rest [Hart,WD] |
| Full Idea: A Fregean concept is a function that assigns to each object a truth value. So instead of the colour green, the concept GREEN assigns truth to each green thing, but falsity to anything else. | |
| From: William D. Hart (The Evolution of Logic [2010], 2) | |
| A reaction: This would seem to immediately hit the renate/cordate problem, if there was a world in which all and only the green things happened to be square. How could Frege then distinguish the green from the square? Compare Idea 8245. |
