Logic and Reasoning: Do the Facts Matter?
Johan van Benthem

Abstract:
Modern logic is undergoing a cognitive turn, side-stepping Frege's
'anti-psychologism'. Collaborations between logicians and colleagues
in more empirical fields are growing, especially in research on
reasoning and information update by intelligent agents. We try to make
more of this common knowledge, and we discuss what this means for our
views of the nature of logic, the sterility of 'barrier theses' like
Frege's, and a modern plausible understanding of 'psychologism'.
