Death induces the sensual person to say: Let us eat and drink, because tomorrow we shall die - but this is sensuality's cowardly lust for life, that contemptible order of things where one lives in order to eat and drink instead of eating and drinking in order to live.

Irony limits, finitizes, and circumscribes and thereby yields truth, actuality, content; it disciplines and punishes and thereby yields balance and consistency.

Happiness is the greatest hiding place for despair.

You train yourself in the art of being mysterious to everyone. My dear friend! What if there were no one, who cared about guessing your riddle, what pleasure would you then take in it?

The unhappy person is never present to themself because they always live in the past or the future.

There is nothing everyone is so afraid of as being told how vastly much he is capable of. You are capable of - do you want to know? - you are capable of living in poverty; you are capable of standing almost any kind of maltreatment, abuse, etc. But you do not wish to know about it, isn't that so? You would be furious with him who told you so, and only call that person your friend who bolsters you in saying: 'No, this I cannot bear, this is beyond my strength, etc.

You love the accidental. A smile from a pretty girl in an interesting situation, a stolen glance, that is what you are hunting for, that is a motif for your aimless fantasy. You who always pride yourself on being an observateur must, in return, put up with becoming an object of observation. Ah, you are a strange fellow, one moment a child, the next an old man; one moment you are thinking most earnestly about the most important scholarly problems, how you will devote your life to them, and the next you are a lovesick fool. But you are a long way from marriage.
