"Anaximander of Miletos, son of Praxiades, a fellow-citizen and associate of Thales, said that the material cause and first element of things was the Infinite, he being the first to introduce this name of the material cause. He says it is neither water nor any other of the so-called elements, but a substance different from them which is infinite" or "from which arise all the heavens and the worlds within them.—Phys, Op. fr. 2 (Dox. p. 476 ; R. P. 16)."
