But, strange to say, those very men, who in our time assert more than any one else that they care for the amelioration of human life, and who are regarded as the leaders in public opinion, affirm that it is not necessary to do that, and that for the amelioration of the condition of men there exist other, more efficacious means. These men assert that the amelioration of human life does not take place in consequence of the internal efforts of the consciousness of individual men and the elucidation and profession of the truth, but in consequence of the gradual change of the common external conditions of life, and that the profession by every individual man of the truth which is not in conformity with the existing order is not only useless, but even harmful, because on the part of the power it provokes oppressions, which keep these individuals from continuing their useful activity in the service of society. According to this doctrine, all the changes in human life take place under the same laws under which they take place in the life of the animals. Thus, according to this doctrine, all the founders of religions, such as Moses and the prophets, Confucius, Lao-tse, Buddha, Christ, and others preached their teachings, and their followers accepted them, not because they loved truth, elucidated it to themselves, and professed it, but because the political, social, and, above all, economic conditions of the nations among whom these teachings appeared and were disseminated were favourable for their manifestation and diffusion. And so the chief activity of a man wishing to serve society and ameliorate the condition of humanity must according to this doctrine be directed, not to the elucidation of the truth and its profession, but to the amelioration of the external political, social, and, above all else, economic conditions. Now the change of these political, social, and economic conditions is accomplished partly by means of serving the government and of introducing into it liberal and progressive principles, partly by contributing to the development of industry and the dissemination of socialistic ideas, and chiefly by the diffusion of scientific education.
