Note 28 — Chapter XVII · THE EPICUREAN VIEWS ON NATURE.
Oswald J. (Oswald Joseph) Reichel translation
Diog. 43; 47; Cic. N. D. i. 20, 54. What idea Epicurus formed to himself of motion we are not told. We learn, however, from Themist. Phys. 52, b, that he replied to Aristotle’s proof of motion, that no constant quantities can be composed of indivisible particles (Phys. vi. 1), by saying: Whatever moves in a given line moves in the whole line, but not in the individual indivisible portions of which the line consists. With reference to the same question, the Epicureans, according to Simpl. Phys. 219, b, asserted that everything moves equally quickly through indivisible spaces. ↑
