Now Epicurus, despite the fact that he employs in his PhysicsLit. physiology, i.e. nature-lore, almost our Natural Philosophy; cf. Introduction, p. xxvi. elements similar to those of Asclepiades,The ultimate particle of Epicurus was the ἄτομοv or atom (lit. non-divisible), of Asclepiades, the ὄρκοv or molecule. Asclepiades took his atomic theory from Epicurus, and he again from Democritus; cf. p. 49, note 5. yet allows that iron is attracted by the lodestone,Lit. Herculean stone. and chaff by amber. He even tries to give the cause of the phenomenon. His view is that the atoms which flow from the stone are related in shape to those flowing from the iron, and so they become easily interlocked with one another; thus it is that, after colliding with each of the two compact masses (the stone and the iron) they then rebound into the middle and so become entangled with each other, and draw the iron after them. So far, then, as his hypotheses regarding causationLit. aetiology. go, he is perfectly unconvincing; nevertheless, he does grant that there is an attraction. Further, he says that it is on similar principles that there occur in the bodies of animals the dispersal of nutrimentAnadosis; cf. p. 62, note 1. and the discharge of waste matters, as also the actions of cathartic drugs.
