[filed under theme 5. Theory of Logic / A. Overview of Logic / 3. Value of Logic ]

Full Idea

In logic the question is not one of contingent but of necessary rules, not how to think, but how we ought to think.

Gist of Idea

Logic gives us the necessary rules which show us how we ought to think

A Reaction

Presumably it aspires to the objectivity of a single correct account of how we all ought to think. I'm sympathetic to that, rather than modern cultural relativism about reason. Logic is rooted in nature, not in arbitrary convention.
