evidence: The Republic, one of the most important dialogues of the ancient Greek philosopher Plato, renowned for its detailed expositions of political and ethical justice and its account of the organization of the ideal state (or city-state)—hence the traditional title of the work. As do other dialogues from Plato’s middle period, and unlike his early or Socratic dialogues, the Republic reflects the positive views of Plato himself rather than the generally skeptical stance of the historical Socrates, who had been Plato’s teacher. ("Socrates" is the main character in most of Plato’s dialogues.) The middle dialogues are literary as well as philosophical masterpieces, containing sensitive portrayals of characters and their interactions, dazzling displays of rhetoric, and striking and memorable tropes and myths, all designed to set off their leisurely explorations of philosophy.
