Zeno of Elea

Zeno of Elea was a Pre-Socratic philosopher and pupil of Parmenides, best known for his paradoxes — ingenious arguments designed to show that motion and plurality are logical impossibilities. His paradoxes of motion, including Achilles and the Tortoise and the Arrow, challenged naive assumptions about space, time, and divisibility, and have fascinated mathematicians and philosophers ever since. Aristotle credited him as the inventor of dialectic.
