Extremes are for us as if they were not, and as if we were not in regard to them; they escape from us, or we from them.

When we see an effect happen always in the same manner, we infer that it takes place by a natural necessity; as, for instance, that the sun will rise to morrow; but nature often deceives us, and will not submit to its own rules.

Words differently arranged have a different meaning, and meanings differently arranged have different effects.

All the unhappiness of men arises from one single fact, that they cannot stay quietly in their own chamber.

If we do not know ourselves to be full of pride, ambition, lust, weakness, misery, and injustice, we are indeed blind. And if, knowing this, we do not desire deliverance, what can we say of a man...?

Human life is thus only a perpetual illusion; men deceive and flatter each other. No one speaks of us in our presence as he does of us in our absence. Human society is founded on mutual deceit; few friendships would endure if each knew what his friend said of him in his absence, although he then spoke in sincerity and without passion.
