Logic and cognitive science

psychologism fights back

Abstract

The aim of the paper is to present the historical context and the motivation of an investigation still in progress, together with a sketch of some of its results. It starts with a brief description of the nature and history of cognitive science. The relation of cognitive science to logic is then considered, from which consideration a conception of logic as a descriptive and mentalist discipline emerges. Such conception clashes with Frege's antipsychologism. The purpose of the investigation is to refute Frege's arguments, considered as objections to the view that there are two logics, both mentalist, one descriptive and one normative.
