[catalogued under 12. Knowledge Sources / A. A Priori Knowledge / 10. A Priori as Subjective]

Full Idea

That logic is a priori consists in the fact that we cannot think illogically.

Gist of Idea

Logic is a priori because we cannot think illogically

Book Reference

-: 'Mind' [-], p.973

A Reaction

A rather startling claim. Presumably we have to say that when we draw a stupid inference, then we weren't really 'thinking'?
