Abstract

Frege's view, that there cannot be a logic of discovery but only a logic of justification based on deduction, and that the goal of logic is the study of deduction, has had a deep impact on the relation of logic to method. Such relation was a very strict one at the origin of logic and from the sixteenth to the first half of the nineteenth century. But, with Frege, it ended up in a divorce, and the subsequent developments of mathematical logic consolidated the divorce.
