A Comparative Analysis of Heraclitus’ Flux, Parmenides’ Stability, and Plato’s Ideas

The issue of ontology and the problem of authentic and unauthentic types of being have always been debated by philosophers since the time of ancient Greece until now. Among Greek philosophers, Heraclitus, Parmenides, and Plato enjoy particular significance because of their particular theories. Heraclitus believed in flux and everlasting change of things and denied stability in being. By contrast, Parmenides denied change and believed in stability and unchangability in being. These two opposite theories were later reformulated in Plato’s theory of Ideas. He developed his particular theory by benefitting from these two theories and employed Heraclitus’ continuous flux in the world of sensibles and Parmenides’ stability of being in the world of Ideas. The present paper comparatively examines the problem of existence from the viewpoint of these three philosophers in order to clarify Plato’s agreement with his two predecessors. A comparison of the ontological views of these three Greek philosophers revealed that Parmenides’ theory of stability (way of truth) and Heraclitus’ theory of unity can be matched with Plato’s world of Ideas. Moreover, the writers conclude that Heraclitus’ theory of flux and Parmenides’ ways of inquiry are compatible with Plato’s world of sensibles.
