Chapter XXIII. Against the Epicureans, Who Deny a Providence, and Refer the Universe to Corporeal Atoms. From Dionysius, Bishop of Alexandria, On Nature

[DIONYSIUS OF ALEXANDRIA] ‘Is the universe one connected whole, as it seems to us and to the wisest of the Greeks, such as Plato and Pythagoras and the Stoics and Heracleitus? Or two, as some one may have supposed, or even many and infinite in number, as it seemed to some others, who by many aberrations of thought and various applications of terms have attempted minutely to divide the substance of the universe, and suppose it to be infinite, and uncreated, and undesigned.

‘For some who gave the name “atoms” to certain imperishable and most minute bodies infinite in number, and assumed a void space of boundless extent, say that these atoms being borne on at random in the void, and accidentally colliding with each other through an irregular drift, become entangled, because they are of many shapes and catch hold of each other, and thus produce the world and all things in it, or rather worlds infinite in number.

‘Epicurus and Democritus were of this opinion: but they disagreed in so far as the former supposed all atoms to be extremely small and therefore imperceptible, while Democritus supposed that there were also some very large atoms. Both, however, affirm that there are atoms, and that they are so called because of their impenetrable hardness.

‘But others change the name of the atoms, and say that they are bodies which have no parts, but are themselves parts of the universe, out of which in their indivisible state all things are composed, and into which they are resolved. And they say that it was Diodorus who invented the name (τὰ ἀμερῆ) of these bodies without parts. But Heracleides, it is said, gave them a different Dame, and called them “weights,” and from him Asclepiades the physician inherited the name.’

After these statements he proceeds to overthrow the doctrine by many arguments, but especially by those which follow: [1]
