With this I have finished such a sketch as I am here able to offer you of the genteel tradition in American philosophy. The subject is complex, and calls for many an excursus and qualifying footnote; yet I think the main outlines are clear enough. The chief fountains of this tradition were Calvinism and transcendentalism. Both were living fountains; but to keep them alive they required, one an agonised conscience, and the other a radical subjective criticism of knowledge. When these rare metaphysical preoccupations disappeared--and the American atmosphere is not favourable to either of them--the two systems ceased to be inwardly understood; they subsisted as sacred mysteries only; and the combination of the two in some transcendental system of the universe (a contradiction in principle) was doubly artificial. Besides, it could hardly be held with a single mind. Natural science, history, the beliefs implied in labour and invention, could not be disregarded altogether; so that the transcendental philosopher was condemned to a double allegiance, and to not letting his left hand know the bluff that his right hand was making. Nevertheless, the difficulty in bringing practical inarticulate convictions to expression is very great, and the genteel tradition has subsisted in the academic mind for want of anything equally academic to take its place. The academic mind, however, has had its flanks turned. On the one side came the revolt of the Bohemian temperament, with its poetry of crude naturalism; on the other side came an impassioned empiricism, welcoming popular religious witnesses to the unseen, reducing science to an instrument of success in action, and declaring the universe to be wild and young, and not to be harnessed by the logic of any school.
