Sextus Empiricus Pyrrhoniae Hypotyposes 3.10.65

[65] The main views held about motion are, I imagine, three. It is assumed by ordinary people ¹ and by some philosophers that motion exists, but by Parmenides, Melissus and certain others ² that it does not exist; while the Sceptics have declared that it is ‟no more” existent than non-existent; for so far as the evidence of phenomena goes it seems that motion exists, whereas to judge by the philosophic argument it would seem not to exist. So when we have exposed the contradiction which lies between those who believe in the existence of motion and those who maintain that motion is naught, if we shall find the counter-arguments of equal weight, ³ we shall be compelled to declare that, so far as these arguments go, motion is ‟no more” existent than non-existent.
