Reason is the slow and torturous method by which those who do not know the truth discover it

Fashion is a tyrant from which nothing frees us. We must suit ourselves to its fantastic tastes. But being compelled to live under its foolish laws, the wise man is never the first to follow, nor the last to keep it.

If we dreamed the same thing every night, it would affect us much as the objects we see every day. And if a common workman were sure to dream every night for twelve hours that he was a king, I believe he would be almost as happy as a king who should dream every night for twelve hours on end that he was a common workman.

We must know where to doubt, where to feel certain, where to submit. He who does not do so, understands not the force of reason.

Muhammad established a religion by putting his enemies to death; Jesus Christ by commanding his followers to lay down their lives.

Curiosity is nothing more than vanity. More often than not we only seek knowledge to show it off.

Look for the truth, it wants to be found.
