Now, according to the law of the division of labour, it is possible to manufacture scientific and artistic factors almost mechanically; and in the space of ten years we shall manufacture more great men of art and science than have been born among all men from the beginning of the world. Nowadays there is a trade corporation of learned men and artists, and by an improved way they prepare all the mental food which is wanted by mankind. And they have prepared so much of it, that there need no longer be any remembrance of the old producers, not only of the very ancient, but also of the more recent,--all their activity, we are told, was the activity of the theological and metaphysical period: all had to be destroyed, and the true, mental activity began some fifty years ago. And in these fifty years we have manufactured so many great men that in a German university there are more of them than have been in the whole world, and of sciences we have manufactured a great number too; for one need only put to a Greek word the termination _logy_, and arrange the subject according to ready-made paragraphs, and the science is created: we have thus manufactured so many sciences that not only cannot one man know them all, but he cannot even remember all their names,--these names alone would fill a large dictionary; and every day new sciences come into existence. In this respect we are like that Finnish teacher who taught the children of a land-owner the Finnish language instead of the French. He taught very well; but there was one drawback,--that nobody, except himself, understood it. We have learned everything very well, but the pity of it is that nobody but ourselves understands it, and that everybody else considers it good-for-nothing nonsense. But to this also there is an explanation: Men do not understand all the utility of the scientific science because they are still under the influence of the theological period of knowledge, that stupid period when all the people of the Hebrew race, as well as the Chinese and Indians and Greeks, understood everything spoken to them by their great teachers. But whatever may be the cause, the fact is this,--that art and science have always existed among mankind; and when they really existed, then they were necessary and intelligible to all men. We are busy about something which we call art and science, and it turns out that what we are busy about is neither necessary nor intelligible to men. So that we have no right to give the name of art or science to our doings. CHAPTER XXXVII But it is said to me, "You only give another narrower definition of art and science, which science does not agree with; but even this does not exclude them, and notwithstanding all you say, there still remains the scientific and art activities of men like Galileo, Bruno, Homer, Michael Angelo, Beethoven, Wagner, and other learned men and artists of lesser magnitude who have devoted all their lives to art and science."
