If a man cannot forget, he will never amount to much.

To defend something is always to discredit it. Let a man have a warehouse full of gold, let him be willing to give away a ducat to every one of the poor - but let him also be stupid enough to begin this charitable undertaking of his with a defense in which he offers three good reasons in justification; and it will almost come to the point of people finding it doubtful whether indeed he is doing something good. But now for Christianity. Yes, the person who defends that has never believed in it.

If a man wants to set up as an innkeeper and he does not succeed, it is not comic. If, on the contrary, a girl asks to be allowed to set up as a prostitute and she fails, as sometimes happens, it is comic.

It belongs to the imperfection of everything human that man can only attain his desire by passing through its opposite.

A man may perform astonishing feats and comprehend a vast amount of knowledge, and yet have no understanding of himself. But suffering directs a man to look within. If it succeeds, then there, within him, is the beginning of his learning.

Imagine hidden in a simpler exterior a secret receptacle wherein the most precious treasure is deposited - there is a spring which has to be pressed, but the spring is hidden, and the pressure must have a certain strength, so that an accidental pressure would not be sufficient. So likewise is the hope of eternity hidden in man's inmost parts, and affliction is the pressure. When it presses the hidden spring, and strongly enough, then the contents appear in all their glory.

Only one human being recognized as one's neighbour is necessary in order to cure a man of self-love

Man is spirit. But what is spirit? Spirit is the self. But what is the self? The self is a relation which relates itself to itself... Man is a synthesis of the infinite and the finite, of the temporal and the eternal, of possibility and necessity, in short, it is a synthesis. A synthesis is a relation between two factors. So regarded, man is not yet a self.

Personality is only ripe when a man has made the truth his own.
