Known only from later sources – the dramatic scene of Plato’s Parmenides (127a–128e), written decades later, and Diogenes Laertius 9.25; that Zeno’s arguments defend Parmenides is widely accepted, a teaching relation as such is not independently attested.

Bergson traced Zeno’s paradoxes to confusing movement with the divisible line it traverses; each step of Achilles is indivisible (Matter and Memory, 1896, ch. 4). H. Bergson, Matière et mémoire (1896), ch. IV; L’Évolution créatrice (1907), ch. IV

Zeno defended Parmenides indirectly, by showing that the common-sense assumptions of plurality and motion lead to absurd consequences. In the most famous paradoxes, swift Achilles can never overtake the tortoise, because he must first reach the point where it was, by which time it has moved on; an arrow in flight is at rest at every instant; and to cross any distance one must first complete infinitely many half-distances. Aristotle called him the inventor of dialectic, the art of refuting a thesis from its own premises. His puzzles about infinity, continuity and time occupied mathematicians and philosophers for more than two thousand years.
Życie i kontekst
Zeno of Elea was a pupil and close associate of Parmenides, active in the fifth century BCE. Plato describes him visiting Athens together with his teacher. Ancient sources report that he died bravely resisting a tyrant. His book of arguments is lost; we know his paradoxes mainly through Aristotle’s Physics and later commentators.
