Some views about patriotism which thus disparage it seem to be based upon a biological conception of it. Not a few writers apparently think of patriotism as a fixed trait of the human organism, even as a kind of mendelian character unrelated to other social qualities. This trait antagonizes social progress, but it is preserved because of secondary values which it represents, such as moral or aesthetic values. According to these views patriotism may be complex, but it acts like a unitary character. It is subject, theoretically, to selection, but as a matter of fact it remains a strong factor in the temperament of nearly all races. But in our view patriotism is something less precise than all this would imply. It is a form in which the most fundamental and general of desires are expressed, in becoming fixated upon their most natural and necessary objects. It is an aspect of the whole process of development of the affective life. Leaving out patriotism (if such a thing were possible) would mean a break in the continuity of the social life. It would leave one group of functions without their natural support in desire. Economists sometimes seem to leave out of account the profound emotional forces and the irresistible tendencies which make social groups. They want organizations without the moods and impulses by which alone social bodies are formed or sustained; and they expect to see organization broken up or interest in it lost while all the conditions that keep alive the passion for it are intact. Patriotism and the existence of nations seem, however, to be the opposite sides of the same fact. And we may assume that so long as nations exist, at any rate, patriotism will exist, and one of the most necessary functions of public education will be the regulation of the motives and feelings which are contained in this sentiment.
