It is, therefore, fundamentally false to stigmatize the American as a materialist, and to deny his idealism. A people is supposed to be thoroughly materialistic when its sphere of interests comprises problems relating only to the world of matter, and fancies itself to be highly idealistic when it is mainly concerned with intangible objects. But this is a pure confusion of ideas. In philosophy, indeed, the distinction between materialistic and idealistic systems of thought is to be referred to the importance ascribed to material and to immaterial objects. Materialism is, then, that pseudo-philosophical theory which supposes that all reality derives from the existence of material objects; and it is an idealistic system which regards the existence of matter as dependent on the reality of thought. But it is mere play on words to call nations realistic or idealistic on the strength of these metaphysical conceptions, instead of using the words in their social and ethical significations. For in the ethical world a materialistic position would be one in which the aim of life was enjoyment, while that point of view would be idealistic which found its motive not in the pleasant consequences of the deed, but in the value of the deed itself.
If we hold fast to the meaning of materialism and idealism in this ethical sense, we shall see clearly that it is entirely indifferent whether the people who have these diametrically opposed views of life are themselves busy with tangible or with intangible things. The man who looks at life materialistically acts, not for the act itself, but for the comfortable consequences which that act may have; and these consequences may satisfy the selfish pleasure as well if they are immaterial as if they are material objects. It is indifferent whether he works for the satisfaction of the appetites, for the hoarding up of treasures, or for the gratification to be found in politics, science, and art. He is still a materialist so long as he has not devotion, so long as he uses art only as a means to pleasure, science only as a source of fame, politics as a source of power; and, in general, so long as the labour that he does is only the means to an end. But the man who is an idealist in life acts because he believes in the value of the deed. It makes no difference to him whether he is working on material or intellectual concerns; whether he speaks or rhymes, paints, governs, or judges; or whether he builds bridges and railroad tracks, drains swamps and irrigates deserts, delves into the earth, or harnesses the forces of nature. In this sense the culture of the Old World threatens at a thousand points to become crassly materialistic, and not least of all just where it most loudly boasts of intellectual wealth and looks down with contempt on everything which is material. And in this sense the culture of the New World is growing to the very purest idealism, and by no means least where it is busy with problems of the natural world of matter, and where it is heaping up economic wealth.
