Zeno of Elea was a pre-Socratic Greek philosopher from Elea, in what is now Southern Italy. He was a student of Parmenides and one of the Eleatics. Zeno defended his instructor's belief in monism, the idea that only one single entity exists that makes up all of reality. He rejected the existence of space, time, and motion. To disprove these concepts, he developed a series of paradoxes to demonstrate why they are impossible. Though his original writings are lost, subsequent descriptions by Plato, Aristotle, Diogenes Laertius, and Simplicius of Cilicia have allowed study of his ideas. 490 BC – 425 BC; died at about 64. Alive at the same time as The Buddha, Sophocles, Hippocrates, Thucydides, and Confucius. Wiki link
