Georg C. Lichtenberg

Once we know our weaknesses they cease to do us any harm.

Man is a masterpiece of creation if for no other reason than that, all the weight of evidence for determinism notwithstanding, he believes he has free will.

Perhaps in time the so-called Dark Ages will be thought of as including our own.

People have to liberate themselves, because liberation is not a single act. It's a question of eternal vigilance. Otherwise, you'll just become enslaved by someone else.

It's good to like yourself, and that only comes from hard work, from doing. But vanity is dangerous; it can trip you badly.

Doubt is part of all religion. All the religious thinkers were doubters.
