To neglect this and treat demand and supply as a summation of original individual estimates involves an inadequacy of the same nature as there would be in explaining fashion as due to a summation of individual ideas about dress. The explanation would be true at a given instant, in fashion as in the market, but in the case of the former no one could fail to perceive how superficial, how delusive, it would be. This is obvious in the case of fashion because its changes are so rapid and conspicuous that we are compelled to notice them, and to see that the individual takes his ideas from the social current. The slower movement of ideas which determines our more stable wants is, however, of the same character, and the superficiality of treating it as originating in the individual is quite as great, amounting to no less than ignoring the historical factors in pecuniary value. The relation of the individual to the system is not essentially different in this case from what we may see in any institution. The ordinary man is a conformer; he lives in the institution and accepts its established valuations, though not without impressing some degree of individuality upon them. In this way we get our ideas and practices regarding religion, marriage, dress, and so on. So in pecuniary matters one accepts in a general way the current values but has a certain individuality in his choices which makes him to some extent a special factor in the market. There is no absolute conformity; we do everything a little differently from any one else; but this does not prevent our being controlled, in a broad way, by the prevailing institutions. This is what the usual economic analysis ignores, or perhaps omits as beyond its proper range. Along with this we have the phenomenon of non-conformity. Individuals of special natural endowment, or unusual situation, or both, depart widely from the type, and initiate new tendencies which, under favorable conditions, may grow, and modify or destroy the old type. These new movements are likely to derive more directly from human nature than the old, and it is commonly true, though not always, that non-conformity represents human-nature values in conflict with those that are more institutional. We can see this process at the present time in the church, in politics, and in the family. It is taking place no less in pecuniary relations, and our expenditure is being humanized as radically, perhaps, as anything else. Things that seemed indispensable twenty-five years ago no longer seem worth while, and claims unthought of then have become irresistible. What changes have come over the budget of the household, of philanthropy, of the state and the church, during this period! One might say much on this topic, but it would amount simply to an exposition, in this field, of the general relation between institutions and human nature.
