“What a chimaera then is man, what a novelty, what a monster, what chaos, what a subject of contradiction, what a prodigy! Judge of all things, yet an imbecile earthworm; depository of truth, yet a sewer of uncertainty and error; pride and refuse of the universe. Who shall resolve this tangle?”

“And while the body is confined to one planet, along which it creeps with pain and difficulty; the thought can in an instant transport us into the most distant regions of the universe; or even beyond the universe, into the unbounded chaos, where nature is supposed to lie in total confusion. What never was seen, or heard or, may yet be conceived; not is any thing beyond the power of thought, except what implies as absolute contradiction.”

“...an animal, at the end of a few months, is what it will be all its life; and its species, at the end of a thousand years, is what it was in the first of those thousand years. Why is man alone subject to becoming an imbecile?”

“No truth is well understood until and unless all the errors it corrects are also understood and all the contradictions found are resolved. It is in the context of a plurality of errors to be corrected and of contradictions to be resolved that the brilliance of the truth shines out and illuminates the scene.”

“What a terrible thing to be a great lord, yet a wicked man.”

“To be feared of a thing and yet to do it, is what makes the prettiest kind of a man.”
