Whoever wants to philosophize must do three things: analyze for himself, argue for himself, and interpret for himself. This book enables one to learn the methods of philosophy through exercises and solutions close to philosophical practice. The book will not replace a logic book, but it contains almost everything that one needs to philosophize. Particular emphasis is put on close textual interpretation. This book is excellent both for the university and for self-study.
