  Immediately after his brief presentation of the Stadium, Aristotle  introduces the most famous of Zeno’s paradoxes of motion, that of  Achilles and the Tortoise: “Second is the one called  ‘Achilles’: this is that the slowest runner never will be overtaken by the fastest; for it is necessary for the one chasing to  come first to where the one fleeing started from, so that it is  necessary for the slower runner always to be ahead some”  (Ph. 6.9, 239b14–18). Simplicius adds the  identification of the slowest runner as the tortoise (in Ph. 1014, 5). Aristotle remarks that this argument is merely a variation  on the Dichotomy, with the difference that it does not depend on  dividing in half the distance taken (Ph. 6.9,  239b18–20), and his analysis, such as it is, emphasizes  that this paradox is to be resolved in the same way as the first  paradox of motion. Whether this is actually the case is debatable.
