No man knows distinctly anything, and no man ever will.

The Ethiopians say that their gods are snub-nosed and black the Thracians that theirs have light blue eyes and red hair.

It takes a wise man to recognize a wise man.

The clear and perfect truth no man has seen, nor will there be anyone who knows about the gods and what I say about all things...; for, however perfect what he says may be, yet he does not know it; all things are matters of opinion.

For all things come from earth, and all things end by becoming earth.

This upper limit, of earth at our feet is visible and touches the air, but below it reaches to infinity

For we are all sprung from earth and water
