Cicero (on the Stoics), Tusculan Disputations 1 ¶100

As this is my opinion, I have explained it in these very words, in my book on Consolation. The origin of the soul of man is not to be found upon earth, for there is nothing in the soul of a mixed or concrete nature, or that has any appearance of being formed or made out of the earth; nothing even humid, or airy, or fiery. For what is there in natures of that kind which has the power of memory, understanding, or thought? which can recollect the past, foresee the future, and comprehend the present? for these capabilities are confined to divine beings; nor can we discover any source from which men could derive them, but from God. There is therefore a peculiar nature and power in the soul, distinct from those natures which are more known and familiar to us. Whatever, then, that is which thinks, and which has understanding, and volition, and a principle of life, is heavenly and divine, and on that account must necessarily be eternal. Nor can God himself, who is known to us, be conceived to be anything else except a soul free and unembarrassed, distinct from all mortal concretion, acquainted with everything, and giving motion to everything, and itself endued with perpetual motion.
