Then in the sphere of abstract science I said to myself: “All humanity lives and develops on the basis of spiritual principles and ideals which guide it. Those ideals are expressed in religions, in sciences, in arts, in forms of government. Those ideals become more and more elevated, and humanity advances to its highest welfare. I am part of humanity, and therefore my vocation is to forward the recognition and the realization of the ideals of humanity.” And at the time of my weak-mindedness I was satisfied with that; but as soon as the question of life presented itself clearly to me, those theories immediately crumbled away. Not to speak of the unscrupulous obscurity with which those sciences announce conclusions formed on the study of a small part of mankind as general conclusions; not to speak of the mutual contradictions of different adherents of this view as to what are the ideals of humanity; the strangeness, not to say stupidity, of the theory consists in the fact that in order to reply to the question facing each man: “What am I?” or “Why do I live?” or “What must I do?” one has first to decide the question: “What is the life of the whole?” (which is to him unknown and of which he is acquainted with one tiny part in one minute period of time). To understand what he is, one man must first understand all this mysterious humanity, consisting of people such as himself who do not understand one another.

I have to confess that there was a time when I believed this. It was the time when I had my own favourite ideals justifying my own caprices, and I was trying to devise a theory which would allow one to consider my caprices as the law of humanity. But as soon as the question of life arose in my soul in full clearness that reply at once flew to dust. And I understood that as in the experimental sciences there are real sciences, and semi-sciences which try to give answers to questions beyond their competence, so in this sphere there is a whole series of most diffused sciences which try to reply to irrelevant questions. Semi-sciences of that kind, the juridical and the social-historical, endeavour to solve the questions of a man’s life by pretending to decide each in its own way, the question of the life of all humanity.
