22437 | Logical languages are rooted in ordinary language, and that connection must be kept [Quine] |
Full Idea: A logical language is not independent of ordinary language. It has its roots in ordinary language, and these roots are not to be severed. | |
From: Willard Quine (Mr Strawson on Logical Theory [1953], V) | |
A reaction: Music to my ears. When you study logic, no one has to teach you what the words 'or' and 'if-then' mean, but they are disambiguated by the symbolism. The roots of logic are in ordinary talk of 'and', 'or' and 'not', which is the real world. |
