Mankind has existed and existed, and never has it existed without the science of that in which the destiny and the welfare of men consist. It is true that the science of the welfare of men appears different on superficial observation, among the Buddhists, the Brahmins, the Hebrews, the Confucians, the Tauists; but nevertheless, wherever we hear of men who have emerged from a state of savagery, we find this science. And all of a sudden it appears that the men of our day have decided that this same science, which has hitherto served as the guiding thread of all human knowledge, is the very thing which hinders every thing. Men erect buildings; and one architect has made one estimate of cost, a second has made another, and a third yet another. The estimates differ somewhat; but they are correct, so that any one can see, that, if the whole is carried out in accordance with the calculations, the building will be erected. Along come people, and assert that the chief point lies in having no estimates, and that it should be built thus--by the eye. And this "thus," men call the most accurate of scientific science. Men repudiate every science, the very substance of science,--the definition of the destiny and the welfare of men,--and this repudiation they designate as science. Ever since men have existed, great minds have been born into their midst, which, in the conflict with reason and conscience, have put to themselves questions as to "what constitutes welfare,--the destiny and welfare, not of myself alone, but of every man?" What does that power which has created and which leads me, demand of me and of every man? And what is it necessary for me to do, in order to comply with the requirements imposed upon me by the demands of individual and universal welfare? They have asked themselves: "I am a whole, and also a part of something infinite, eternal; what, then, are my relations to other parts similar to myself, to men and to the whole--to the world?" And from the voices of conscience and of reason, and from a comparison of what their contemporaries and men who had lived before them, and who had propounded to themselves the same questions, had said, these great teachers have deduced their doctrines, which were simple, clear, intelligible to all men, and always such as were susceptible of fulfilment. Such men have existed of the first, second, third, and lowest ranks. The world is full of such men. Every living man propounds the question to himself, how to reconcile the demands of welfare, and of his personal existence, with conscience and reason; and from this universal labor, slowly but uninterruptedly, new forms of life, which are more in accord with the requirements of reason and of conscience, are worked out.
