Logic and Heuristic Logic After the 14th Century

The speakers discuss the progress made in logic and heuristic logic after the 14th century, from the development of propositional logic to the emergence of a theory of discovery. They highlight the influence of rhetoric on scholastic philosophers and the concept of tight connections in the logic of inference. The chapter concludes with a discussion on the development of the conception of validity and the search for tighter connections in the late 14th century.
