Men are so completely fools by necessity that he is but a fool in a higher strain of folly who does not confess his foolishness.

The sum of a man's problems come from his inability to be alone in a silent room.

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.

Most of man's trouble comes from his inability to be still.

Man is so made that if he is told often enough that he is a fool he believes it.

Man is so made that by continually telling him he is a fool he believes it, and by continually telling it to himself he makes himself believe it. For man holds an inward talk with himself, which it pays him to regulate.

Man is full of desires: he loves only those who can satisfy them all. "This man is a good mathematician," someone will say. But I have no concern for mathematics; he would take me for a proposition. "That one is a good soldier." He would take me for a besieged town. I need, that is to say, a decent man who can accommodate himself to all my desires in a general sort of way.

Man is so great that his greatness appears even in the consciousness of his misery. A tree does not know itself to be miserable. It is true that it is misery indeed to know one's self to be miserable; but then it is greatness also. In this way, all man's miseries go to prove his greatness. They are the miseries of a mighty potentate, of a dethroned monarch.

I can well conceive a man without hands, feet, head. But I cannot conceive man without thought; he would be a stone or a brute.
