Rh clear. That the factor of scarcity creates the necessity for economy is also fairly obvious. That it is the source also of the conflict of human interests out of which most of our moral and social problems grow may not be quite so obvious, but the following considerations will show it to be true. The fact of scarcity means that man has wants for which nature does not spontaneously provide. This in turn implies a lack of harmony between man and nature, which it is the purpose of productive industry to restore.

That phase of the disharmony between man and nature which takes the form of scarcity gives rise also to a disharmony between man and man. Where there is scarcity there will be two men wanting the same thing; and where two men want the same thing there is an antagonism of interests. Where there is an antagonism of interests between man and man, there will be questions to be settled, questions of right and wrong, of justice and injustice; and these questions could not arise under any other condition. The antagonism of interests is, in other words, what gives rise to a moral problem, and it is, therefore, about the most fundamental fact in sociology and moral philosophy.

This does not overlook the fact that there are many harmonies between man and man, as there are between man and nature. There may be innumerable cases where all human interests harmonize, but these give rise to no problem and therefore we do not need to concern ourselves with them. As already pointed out, there are many cases where man and nature are in complete harmony. There are things, for example, which nature furnishes in sufficient abundance to satisfy all our wants, but these also give rise to no problem. Toward these non-economic goods our habitual attitude is one of indifference or unconcern. Where the relations between man and nature are perfect, why should we concern ourselves about them? But the whole industrial world is bent on improving those relations where they are imperfect. Similarly with the relations between man and man; where they are perfect, that is, where interests are all harmonious, why should we concern ourselves about them? As a matter of fact we do not. But where they are imperfect, where
