12. Knowledge Sources / A. A Priori Knowledge / 8. A Priori as Analytic

6284	If a tautology is immune from revision, why would that make it true? [Putnam]
	Full Idea: If we held, say, 'All unmarried men are unmarried' as absolutely immune from revision, why would this make it true?
	From: Hilary Putnam (Meaning and the Moral Sciences [1978], Pt Four)
	A reaction: A very nice question. Like most American philosophers, Putnam accepts Quine's attack on the unrevisability of analytic truths. His point here is that defenders of analytic truths are probably desperate to preserve basic truths, but it won't work.
