5. Theory of Logic / K. Features of Logics / 1. Axiomatisation

16886	The truth of an axiom must be independently recognisable [Frege]
	Full Idea: It is part of the concept of an axiom that it can be recognised as true independently of other truths.
	From: Gottlob Frege (On Euclidean Geometry [1900], 183/168), quoted by Tyler Burge - Frege on Knowing the Foundations 4
	A reaction: Frege thinks the axioms of arithmetic all reside in logic.
