Der Mensch kann tun was er will; er kann aber nicht wollen was er will.

Man can do what he wills but he cannot will what he wills.

However, the struggle with that sentinel is, as a rule, not so hard as it may seem from a long way off, mainly in consequence of the antagonism between the ills of the body and the ills of the mind. If we are in great bodily pain, or the pain lasts a long time, we become indifferent to other troubles; all we think about is to get well. In the same way great mental suffering makes us insensible to bodily pain; we despise it; nay, if it should outweigh the other, it distracts our thoughts, and we welcome it as a pause in mental suffering. It is this feeling that makes suicide easy; for the bodily pain that accompanies it loses all significance in the eyes of one who is tortured by an excess of mental suffering. This is especially evident in the case of those who are driven to suicide by some purely morbid and exaggerated ill-humor. No special effort to overcome their feelings is necessary, nor do such people require to be worked up in order to take the step; but as soon as the keeper into whose charge they are given leaves them for a couple of minutes, they quickly bring their life to an end.
When, in some dreadful and ghastly dream, we reach the moment of greatest horror, it awakes us; thereby banishing all the hideous shapes that were born of the night. And life is a dream: when the moment of greatest horror compels us to break it off, the same thing happens.

There is not much to be got anywhere in the world. It is filled with misery and pain; if a man escapes these, boredeom lies in wait for him at every corner. Nay more; it is evil which generally has the upper hand, and folly that makes the most noise. Fate is cruel and mankind pitiable.

Of how many a man may it not be said that hope made a fool of him until he danced into the arms of death!

If you want a safe compass to guide you through life, and to banish all doubt as to the right way of looking at it, you cannot do better than accustom yourself to regard this world as a penitentiary... If you accustom yourself to this view of life you will regulate your expectations accordingly, and cease to look upon all its disagreeable incidents, great and small, its sufferings, its worries, its misery, as anything unusual or irregular; nay, you will find that everything is as it should be, in a world where each of us pays the penalty of existence in his own peculiar way.

If you try to imagine as nearly as you can what an amount of misery, pain, and suffering of every kind the sun shines upon in its course, you will admit that it would be much better if on the earth as little as on the moon the sun were able to call forth the phenomena of life; and if, here as there, the surface were still in a crystalline state".
