De Somniis (lib. i-ii)

There were, therefore, three persons who uttered atrocious words which were to reach even to heaven; these men devoted themselves to studies against nature, or rather against their own souls, saying that this universe was the only thing which was perceptible to the outward senses, and visible, having never been created, and being never destined to be destroyed, but being uncreated and imperishable, not requiring any superintendence, or care, or regulation, or management.

Afterwards piling up fresh attempts one upon another, they built up a doctrine which was not approved, and raised it to a height like a tower; for it is said, "And the whole earth spoke one language," [*](Genesis xi. 1. ) an inharmonious agreement of all the portions of the soul, for the purpose of overthrowing that which is the most comprehensive of all existing principles, namely, authority.
