The moral power of the word: Ethical literature in Antiquity

According to an old legend, during the Messenian Wars in Laconia in the 8^th and 7^th centuries BC, the Athenians sent the poet Tyrtaeus to the Spartans who were close to being defeated; he aroused in them the fighting spirit and renewed Spartan virtues. Philosophers in antiquity believed in the psychagogical power of the word, and this belief provided the foundation for ancient ethical literature, whose main purpose was to call for a spiritual transformation and to convert to philosophy. In this paper, I would like to demonstrate what tradition philosophy referred to in these efforts; what concept of man supported that belief; finally, what literary genres were used by ancient philosophers in ethics.
