All the shrewdness of 'man' seeks one thing: to be able to live without responsibility.

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.

So to be sick unto death is, not to be able to die-yet not as though there were hope of life; no, the hopelessness in this case is that even the last hope, death, is not available. When death is the greatest danger, one hopes for life; but when one becomes acquainted with an even more dreadful danger, one hopes for death. So when the danger is so great that death has become one's hope, despair is the disconsolateness of not being able to die.

As a result, people have hitherto been beating the air in their struggle against objections, because they have fought intellectually with doubt instead of fighting morally with rebellion.
