The sole meaning of life is to serve humanity.

Involuntarily it appeared to me that there, somewhere, was someone who amused himself by watching how I lived for thirty or forty years: learning, developing, maturing in body and mind, and how, having with matured mental powers reached the summit of life from which it all lay before me, I stood on that summit -- like an arch-fool -- seeing clearly that there is nothing in life, and that there has been and will be nothing. And he was amused... But whether that "someone" laughing at me existed or not, I was none the better off. I could give no reasonable meaning to any single action or to my whole life. I was only surprised that I could have avoided understanding this from the very beginning -- it has been so long known to all. Today or tomorrow sickness and death will come (they had come already) to those I love or to me; nothing will remain but stench and worms. Sooner or later my affairs, whatever they may be, will be forgotten, and I shall not exist. Then why go on making any effort?... How can man fail to see this? And how go on living? That is what is surprising! One can only live while one is intoxicated with life; as soon as one is sober it is impossible not to see that it is all a mere fraud and a stupid fraud! That is precisely what it is: there is nothing either amusing or witty about it, it is simply cruel and stupid.

Then these moments of perplexity began to recur oftener and oftener, and always in the same form. They were always expressed by the questions: What is it for? What does it lead to? At first it seemed to me that these were aimless and irrelevant questions. I thought that it was all well known, and that if I should ever wish to deal with the solution it would not cost me much effort; just at present I had no time for it, but when I wanted to I should be able to find the answer. The questions however began to repeat themselves frequently, and to demand replies more and more insistently; and like drops of ink always falling on one place they ran together into one black blot. Then occurred what happens to everyone sickening with a mortal internal disease. At first trivial signs of indisposition appear to which the sick man pays no attention; then these signs reappear more and more often and merge into one uninterrupted period of suffering. The suffering increases, and before the sick man can look round, what he took for a mere indisposition has already become more important to him than anything else in the world -- it is death! That is what happened to me.

It was long before I could believe that human learning had no clear answer to this question. For a long time it seemed to me, as I listened to the gravity and seriousness wherewith Science affirmed its positions on matters unconnected with the problem of life, that I must have misunderstood something. For a long time I was timid in the presence in learning, and I fancied that the insufficiency of the answers which I received was not its fault, but was owing to my own gross ignorance, but this thing was not a joke or a pastime with me, but the business of my life, and I was at last forced, willy-nilly, to the conclusion that these questions of mine were the only legitimate questions underlying all knowledge, and that it was not I that was in fault in putting them, but science in pretending to have an answer for them.

The meaning of life is life.
