Seekers for gold dig much earth, and find little gold. Nature loves to hide. The lord at Delphi neither speaks nor conceals, but gives a sign. And the Sibyl with raving mouth, uttering words solemn, unadorned, and unsweetened, reaches with her voice a thousand years because of the god in her. What can be seen, heard, and learned, this I prize.
Eyes are more exact witnesses than ears.
This order, the same for all things, no one of gods or men has made, but it always was, and is, and ever shall be, an ever-living fire, kindling according to fixed measure, and extinguised according to fixed measure. Want and satiety. Fire coming upon all things will test them, and lay hold of them. The thunderbolt directs the course of all things. If there were no sun, it would be night.
