This volume concerns Theophrastus, Aristotle's pupil and successor as head of the Peripatetic School. The focus is twofold. First, it deals with discoveries and inventions, both useful and pleasurable, and more generally changes that transformed the way people live. Theophrastus wrote a work entitled On Discoveries, which may be regarded as cultural history. Second, the volume focuses on proverbs: familiar sayings containing useful truths that have been observed by earlier generations and passed on in a form that is concise and attractive. Theophrastus wrote a work entitled On Proverbs and made use of proverbs in his writings on ethics, rhetoric and humor. He recognized their importance in educating the young and maintaining the traditions of an earlier age.
