The transformation in attitude, to which I referred, is the growing belief that the proper business of intelligence is discrimination of multiple and present goods and of the varied immediate means of their realization; not search for the one remote aim. The progress of biology has accustomed our minds to the notion that intelligence is not an outside power presiding supremely but statically over the desires and efforts of man, but is a method of adjustment of capacities and conditions within specific situations. History, as the lecturer on that subject told us, has discovered itself in the idea of process. The genetic standpoint makes us aware that the systems of the past are neither fraudulent impostures nor absolute revelations; but are the products of political, economic, and scientific conditions whose change carries with it change of theoretical formulations. The recognition that intelligence is properly an organ of adjustment in difficult situations makes us aware that past theories were of value so far as they helped carry to an issue the social perplexities from which they emerged. But the chief impact of the evolutionary method is upon the present. Theory having learned what it cannot do, is made responsible for the better performance of what needs to be done, and what only a broadly equipped intelligence can undertake: study of the conditions out of which come the obstacles and the resources of adequate life, and developing and testing the ideas that, as working hypotheses, may be used to diminish the causes of evil and to buttress and expand the sources of good. This program is indeed vague, but only unfamiliarity with it could lead one to the conclusion that it is less vague than the idea that there is a single moral ideal and a single moral motive force. From this point of view there is no separate body of moral rules; no separate system of motive powers; no separate subject-matter of moral knowledge, and hence no such thing as an isolated ethical science. If the business of morals is not to speculate upon man’s final end and upon an ultimate standard of right, it is to utilize physiology, anthropology, and psychology to discover all that can be discovered of man, his organic powers and propensities. If its business is not to search for the one separate moral motive, it is to converge all the instrumentalities of the social arts, of law, education, economics, and political science upon the construction of intelligent methods of improving the common lot. If we still wish to make our peace with the past, and to sum up the plural and changing goods of life in a single word, doubtless the term happiness is the one most apt. But we should again exchange free morals for sterile metaphysics, if we imagine that “happiness” is any less unique than the individuals who experience it; any less complex than the constitution of their capacities, or any less variable than the objects upon which their capacities are directed.
