Title: How to Adopt a Logic
What is commonly referred to as the Adoption Problem is a challenge to the idea that the principles of logic can be rationally revised. The argument is based on a reconstruction of unpublished work by Saul Kripke. As the reconstruction has it, Kripke essentially extends the scope of Willard van Orman Quine’s regress argument against conventionalism to the possibility of adopting new logical principles. In this talk I want to discuss the scope of this challenge. Are all revisions of logic subject to the regress problem? If not, are there interesting cases of logical revisions that are subject to the regress problem? I will argue that both questions should be answered negatively. (The talk is based on joint work with Carlo Nicolai.)

The Centre for Logic and Language hosts a regular seminar series - the Logic, Epistemology and Metaphysics Forum (LEM). The forum generally meets fortnightly in term time.
