Human Behavior Flows From Three Main

This paraphrase derives from Plato's tripartite psychology of the soul (psyche), most fully developed in Republic Book IV (439–441). Plato divided the soul into three parts: the rational (logistikon), the spirited or emotional (thymoeides), and the appetitive or desiring (epithymetikon). Virtuous character consists in the rational part governing the other two, while vice is the inverse. Aristotle criticised this division and proposed his own account of soul in De Anima, but Plato's tripartite model remained foundational for centuries of moral psychology.
