which the natural rivalry of interests persists. Saying nothing of the barbaric notion that wives and children are themselves property, even in the higher types of society it is the desire to safeguard those to whom one is bound by ties of natural affection, by sharing the advantages of property with them, which furnishes the basis for the legal definition of the family group.
THE FUNDAMENTAL POSITION OF ECONOMICS
Closely associated with the right of property—as parts of it in fact—is a group of rights such as that of contract, of transfer, of bequest, and a number of other things with which lawyers occupy themselves. It would be difficult to find any question in the whole science of jurisprudence, or of ethics, or politics, or any of the social sciences for that matter, which does not grow out of the initial fact of economic scarcity and the consequent antagonism of interests among men. This reveals, as nothing else can, the underlying unity of all the social sciences, that is, of all the sciences which have to do with the relations between man and man; and it shows very clearly that the unifying principle is an economic one. Even the so-called gregarious instinct may very probably be the product of the struggle for existence, which, in turn, is the product of scarcity—the advantage of acting in groups being the selective agency in the development of this instinct. But that question, like a great many others, lies beyond the field of positive knowledge. This does not necessarily constitute economics as the "master science," with the other social sciences subordinate to it; but it does signify that, if there is such a thing as a master science, economics has the first claim to that position among the social sciences. The economic problem is the fundamental one, out of which all other social and moral problems have grown.
ECONOMIC COMPETITION
This conflict of man with man, when uncontrolled by society, either through moral codes or legal procedure, does not differ materially from the struggle for existence among brutes. But there is no human society which does not control the struggle in some way. In fact the one purpose for which organized society exists is that of
