The Easy Argument Against Noncontractive Logics Doesn’t Work (Shay Logan)

The Logic and Metaphysics Workshop will meet on March 1st from 4:15-6:15 (NY time) via Zoom for a talk by Shay Logan (Kansas State).

Title: The Easy Argument Against Noncontractive Logics Doesn’t Work

Abstract: The Easy Argument against noncontractivism is the argument that essentially amounts to pointing out that contraction is just repeating oneself. The purpose of this talk is to explain why the Easy Argument fails. I show first that the Easy Argument fails by being insufficiently precise, since there are many ways we can combine premises in an argument. After correcting for this, the Easy Argument then fails by being straightforwardly invalid. The premises required to correct for *this* failure, however, have controversial consequences. Altogether, it seems arguments against noncontractive logics, if there are any, will be Hard—not Easy—Arguments.
