ABSTRACT
The ordinary objects of scientific discourse are more specialized and artificial, and in that measure are more susceptible of intellectual analysis. The ideal of science as demonstrative knowledge excludes the possibility of the obscurity of the very objects of the demonstration; and in the dominant traditions of the philosophy of science, such an obscurity would destroy the claim of science to be knowledge of any worthwhile sort. The account given so far of the further evolution of the materials which may become scientific knowledge is still deficient in one respect. The first is that the continuous increase in the number of solved problems is not at all the same as the deepening and enrichment of scientific knowledge. To reduce the body of scientific knowledge to such elements may seem to dissolve its unity, and indeed to destroy its reality, leaving only a heap of pragmatically justified tools.
