"The book aims to be the best single edition available for introductory Frege courses. It is a well organized, reasonably priced one-stop Frege shop. It is too convenient not to be used in introductory courses on Frege; in fact, as a single volume, it has no competition I can think of. The general conception is excellent. It is easily readable by graduates or advanced under graduates. The forty-six page introduction and notes to the translations make it useful also for Frege scholars. The book's virtues are strong. I recommend it for courses on Frege, philosophy of language, philosophy of logic, and analytic philosophy." Jan Dejnozka, History and Philosophy of Logic
