Greek and medieval knowledge accepted the world in its qualitative variety, and regarded nature's processes as having ends, or in technical phrase as teleological. New science was expounded so as to deny the reality of all qualities in real, or objective, existence. Sounds, colors, ends, as well as goods and bads, were regarded as purely subjective—as mere impressions in the mind. Objective existence was then treated as having only quantitative aspects—as so much mass in motion, its only differences being that at one point in space there was a larger aggregate mass than at another, and that in some spots there were greater rates of motion than at others. Lacking qualitative distinctions, nature lacked significant variety. Uniformities were emphasized, not diversities; the ideal was supposed to be the discovery of a single mathematical formula applying to the whole universe at once from which all the seeming variety of phenomena could be derived. This is what a mechanical philosophy means.
Such a philosophy does not represent the genuine purport of science. It takes the technique for the thing itself; the apparatus and the terminology for reality, the method for its subject matter. Science does confine its statements to conditions which enable us to predict and control the happening of events, ignoring the qualities of the events. Hence its mechanical and quantitative character. But in leaving them out of account, it does not exclude them from reality, nor relegate them to a purely mental region; it only furnishes means utilizable for ends. Thus while in fact the progress of science was increasing man's power over nature, enabling him to place his cherished ends on a firmer basis than ever before, and also to diversify his activities almost at will, the philosophy which professed to formulate its accomplishments reduced the world to a barren and monotonous redistribution of matter in space. Thus the immediate effect of modern science was to accentuate the dualism of matter and mind, and thereby to establish the physical and the humanistic studies as two dis-
