Whatever we do, do not let us deceive ourselves. We all know very well the motives for building railways and factories, and for producing kerosene and matches. An engineer builds a railway for the government, to facilitate wars, or for the capitalists for their financial purposes. He makes machines for manufacturers for his own advantage and for the profit of capitalists. All that he makes or plans he does for the purpose of the government, the capitalists, and other rich people. His most skilful inventions are either directly harmful to the people, such as guns, torpedoes, solitary prisons, and so on; or they are not only useless but quite inaccessible to them, such as electric light, telephones, and the innumerable improvements of comfort; or lastly, they deprave the people and rob them of their last kopek, that is, their last labour, for spirits, wine, beer, opium, tobacco, finery, and all sorts of trifles. But if it happens sometimes that the inventions of men of science and the works of engineers, are of use to the people, as, for instance, railways, calicoes, steel, scythes, it only proves that in this world of ours everything is mutually connected, and that out of every hurtful activity there may arise an accidental good for those to whom the activity was hurtful. Men of science and of art could say that their activity was useful for the people, only if in their activity they have aimed at serving the people, as they now aim to serve the government and capitalists. We could have said that, only if the men of science and art made the wants of the people their object; but such is not the case. All learned men are occupied with their sacred businesses, which lead to the investigation of protoplasms, the spectrum analysis of stars, and so on: but concerning investigations as to how to set an axe, or with what kind it is more advantageous to hew; which saw is the most handy; with what flour bread shall be made, how it may best be kneaded, how to set it to rise; how to heat and to build stoves; what food, drink or crockery-ware it is best to use; what mushrooms may be eaten, and how they may be prepared more conveniently,--science never troubles itself, or does so very slightly. Yet all this is the business of science. I know that, according to its own definition, science must be useless; but this is only an excuse, and a very impudent one. The business of science is to serve people. We have invented telegraphs, telephones, phonographs, but what improvements have we made in the life of the people? We have catalogued two millions of insects! but have we domesticated a single animal since biblical times, when all our animals had long been domesticated, and still the elk and the deer, and the partridge and the grouse and the wood-hen, are wild? Botanists have discovered the cells, and in the cells protoplasms and in protoplasms something else, and in this something else again.
