"The fourth way out is that of weakness. It consists in seeing the truth of the situation and yet clinging to life, knowing in advance that nothing can come of it. People of this kind know that death is better than life, but not having the strength to act rationally - to end the deception quickly and kill themselves - they seem to wait for something. This is the escape of weakness, for if I know what is best and it is within my power, why not yield to what is best? ... I found myself in that category. So people of my class evade the terrible contradiction in four ways. Strain my attention as I would, I saw no way except those four. One way was not to understand that life is senseless, vanity, and an evil, and that it is better not to live. I could not help knowing this, and when I once knew it could not shut my eyes to it. The second way was to use life such as it is without thinking of the future. And I could not do that. I, like Sakya Muni, could not ride out hunting when I knew that old age, suffering, and death exist. My imagination was too vivid. Nor could I rejoice in the momentary accidents that for an instant threw pleasure to my lot. The third way, having understood that life is evil and stupid, was to end it by killing oneself. I understood that, but somehow still did not kill myself. The fourth way was to live like Solomon and Schopenhauer - knowing that life is a stupid joke played upon us, and still to go on living, washing oneself, dressing, dining, talking, and even writing books. This was to me repulsive and tormenting, but I remained in that position."
