“Therefore do not deceive yourself! Of all deceivers fear most yourself!”

“Do you not know that there comes a midnight hour when every one has to throw off his mask? Do you believe that life will always let itself be mocked? Do you think you can slip away a little before midnight in order to avoid this? Or are you not terrified by it? I have seen men in real life who so long deceived others that at last their true nature could not reveal itself;... In every man there is something which to a certain degree prevents him from becoming perfectly transparent to himself; and this may be the case in so high a degree, he may be so inexplicably woven into relationships of life which extend far beyond himself that he almost cannot reveal himself. But he who cannot reveal himself cannot love, and he who cannot love is the most unhappy man of all.”

“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?”

“Your own tactic is to train yourself in the art of becoming enigmatic to everybody. My young friend, suppose there was no one who troubld himself to guess your riddle--what joy, then, would you have in it?”

“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.”

“Of all ridiculous things the most ridiculous seems to me, to be busy — to be a man who is brisk about his food and his work. Therefore, whenever I see a fly settling, in the decisive moment, on the nose of such a person of affairs; or if he is spattered with mud from a carriage which drives past him in still greater haste; or the drawbridge opens up before him; or a tile falls down and knocks him dead, then I laugh heartily.”

“Let us speak of this in purely human terms. Oh! how pitiable a person who has never felt the loving urge to sacrifice everything for love, who has therefore been unable to do so!”
