5. Theory of Logic / A. Overview of Logic / 1. Overview of Logic

18794	Logic has precise boundaries, and is the formal rules for all thinking [Kant]
	Full Idea: The boundaries of logic are determined quite precisely by the fact that logic is the science that exhaustively presents and strictly proves nothing but the formal rules of all thinking.
	From: Immanuel Kant (Critique of Pure Reason [1781], B Pref ix)
	A reaction: Presumably it does not give the rules for ridiculous thinking, so more will be required. The interesting bit is the universality of the claim.

5. Theory of Logic / A. Overview of Logic / 3. Value of Logic

22275	Logic gives us the necessary rules which show us how we ought to think [Kant]
	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.
	From: Immanuel Kant (Wiener Logik [1795], p.16), quoted by Michael Potter - The Rise of Analytic Philosophy 1879-1930 02 'Trans'
	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.
