Plato versus Parmenides investigates the concept of genesis, or coming into being, a problem that has absorbed the greatest philosophical thinkers. Robert J. Roecklein explores two philosophical giants who tackled this issue: Plato and Parmenides from Elea. Particularly interesting to Roecklein is how the respective arguments of reality, or lack thereof, of coming into being functions as a political barometer: how Plato and Parmenides sketch foundations for political regimes. Plato and Parmenides, philosophers of immeasurable respect and influence, represented two sides of a fierce debate. On one side, Parmenides gives the famous argument that coming into being cannot possibly be a reality in nature. The other side, Plato proves in his dialogue the Parmenides that coming into being is a very real thing in nature. He argues that perception does indeed provide accurate information about the external world. In Plato versus Parmenides, Robert J. Roecklein presents the great debate between these two schools, and examines the disposition of other PreSocratic philosophers who were influenced by these great intellectual rivals.
