We should know mankind better if we were not so anxious to resemble one another.

The most difficult thing is what is thought to be the simplest; to really see the things which are before your eyes.

The dangers of life are infinite, and among them is safety.

Is it not enough that we cannot make one another happy, must we also rob one another of the pleasures that any heart may permit itself now and then? And name me a person who in a bad mood will be decent enough to hide it, to bear it alone, without destroying the joy around him. Is it not rather an inner dissatisfaction with our own unworthiness, a dislike of ourselves that is always associated with envy aggravated by foolish conceit? We see people happy and not made happy by us, and that is unbearable.

Science has been seriously retarded by the study of what is not worth knowing and of what is not knowable.
