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

13831	Logic is based on transitions between sentences [Prawitz]
	Full Idea: I agree entirely with Dummett that the right way to answer the question 'what is logic?' is to consider transitions between sentences.
	From: Dag Prawitz (Gentzen's Analysis of First-Order Proofs [1974], §04)
	A reaction: I always protest at this point that reliance on sentences is speciesism against animals, who are thereby debarred from reasoning. See the wonderful Idea 1875 of Chrysippus. Hacking's basic suggestion seems right. Transition between thoughts.
