When I say that the refusal is conscious I do not mean merely that scientists tell themselves that they must ignore their prejudices. They have developed an elaborate method for detecting and discounting their prejudices. It consists of instruments of precision, an accurate vocabulary, [p239] controlled experiment, and the submission not only of their results but of their processes to the judgment of their peers. This method provides a body in which the spirit of disinterestedness can live, and it might be said that modern science, not in its crude consequences but in its inward principle, not, that is to say, as manifested in automobiles, electric refrigerators, and rayon silk, but in the behavior of the men who invent and perfect these things, is the actual realization in a practicable mode of conduct which can be learned and practiced, of the insight of high religion. The scientific discipline is one way in which this insight, hitherto lyrical and personal and apart, is brought down to earth and into direct and decisive contact with the concerns of mankind. It is no exaggeration to say that pure science is high religion incarnate. No doubt the science we have is not the whole incarnation, but as far as it goes it translates into a usable procedure what in the teaching of the sages has been an esoteric insight. Scientific method can be learned. The learning of it matures the human character. Its value can be demonstrated in concrete results. Its importance in human life is indisputable. But the insight of high religion as such could be appreciated only by those who were already mature; it corresponded to nothing in the experience and the necessities of the ordinary man. It could be talked about but not taught; it could inspire only the few who were somehow already inspired. With the discovery of scientific method the insight has ceased to be an intangible and somewhat formless idea and has become an organized effort which moves mankind more profoundly than anything else in human affairs. Therefore, [p240] what was once a personal attitude on the part of a few who were somewhat withdrawn and disregarded has become the central principle in the careers of innumerable, immensely influential, men.
