... Parmenides, who for a time was initiated both into the Pythagorean mysteries and their mathematical methods, no doubt passed on his teachings to his leading student, Zeno (490-430 B.C.E.) - who may or may not himself have been part of the Pythagorean training. In any case, Zeno came armed not with allegory or myth but with mathematically precise demonstration that things were not as they seemed.

... Zeno supported Parmenides' philosophy with several arguments against the possibility of the key central concept ... of motion. The influence of these paradoxes on philosophical, mathematical and scientific thought has been significant and continuous. As the 20th century philosopher Alfred North Whitehead notes,

"No one has ever touched Zeno without refuting him, and every century thinks it worthwhile to refute him."
