One of the world's most influential logicians, Jaakko Hintikka is a leading figure on the international philosophical scene. Here, he responds to his critics. The 27 critical and descriptive essays in this book, written by important scholars from a variety of fields, challenge Hintikka's innovations in philosophy, logic, and linguistics. His replies, and the essays themselves, all previously unpublished, form a lively, provocative exchange of ideas. Also included is an intellectual autobiography and a complete bibliography of Hintikka's writings.
