Parmenides of Elea was a Pre-Socratic Greek philosopher who founded the Eleatic school of philosophy. His poem 'On Nature' argued that reality is one, unchanging, and eternal, and that change and plurality are illusions of the senses. He profoundly influenced Plato and the subsequent course of Western metaphysics by prioritizing reason over sensory experience.
