Abstract
While there is no principle of evil (archē kakou) for Plato, evil does exist in the Platonic framework in various ways, and these help to illuminate other important and overlooked features of Platonic thought: human freedom and the ability to choose and act. Using the Timaeus as the basis of investigation, this paper examines the world-soul and its relation to the human soul in order to understand Plato’s notion of congruency between parts and the whole. It specifically highlights the importance of the three fundamental characteristics of the cosmos—singularity, proportionalism, and completeness—and their ability to explain the human being. The paper argues that Plato understands evil as basic incongruence on all levels, but specifically active incongruence on the human level. The incongruence between the human and the cosmic levels of evil reveals perhaps the most important aspect of the Platonic framework, the possibility for progress toward the good.
