This book presents a remarkable diversity of contemporary opinions on the prospects of addressing philosophical topics from a psychological perspective. It considers the history and philosophical merits of psychologism, and looks systematically at psychologism in phenomenology, cognitive science, epistemology, logic, philosophy of language, philosophical semantics, and artificial intelligence.
