Marcus Tullius Cicero,
Cicero's Tusculan Disputations
“ Thus by their continual motions backward and forward, upward and downward, the conjunction of the several parts of the universe is preserved; a union which, in the beauty we now behold it, must be eternal, or at least of a very long duration, and almost for an infinite space of time; and, whichever it is, the universe must of consequence be governed by nature. ”
