To say that the American is an idealist is to commit a thoroughgoing platitude. Like most platitudes, the statement is annoying because from one point of view it is indisputably just, while from another it does not seem to fit the facts. With regard to our tradition, it is indisputable. Of the immigrants who since the seventeenth century have been pouring into this continent a proportion large in number, larger still in influence, has been possessed of motives which in part at least were idealistic. If it was not the desire for religious freedom that urged them, it was the desire for personal freedom; if not political liberty, why then economic liberty (for this too is idealism), and the opportunity to raise the standard of life. And of course all these motives were strongest in that earlier immigration which has done most to fix the state of mind and body which we call being American. I need not labor the argument. Our political and social history support it; our best literature demonstrates it, for no men have been more idealistic than the American writers whom we have consented to call great. Emerson, Thoreau, Hawthorne, Whitman--was idealism ever more thoroughly incarnate than in them? And this idealism--to risk again a platitude--has been in the air of America. It has permeated our religious sects, and created several of them. It has given tone to our thinking, and even more to our feeling. I do not say that it has always, or even usually, determined our actions, although the Civil War is proof of its power. Again and again it has gone aground roughly when the ideal met a condition of living--a fact that will provide the explanation for which I seek. But optimism, "boosting," muck- raking (not all of its manifestations are pretty), social service, religious, municipal, democratic reform, indeed the "uplift" generally, is evidence of the vigor, the bumptiousness of the inherited American tendency to pursue the ideal. No one can doubt that in 1918 we believed, at least, in idealism. Nevertheless, so far as the average individual is concerned, with just his share and no more of the race-tendency, this idealism has been suppressed, and in some measure perverted. It is this which explains, I think, American sentimentalism.
