It may be well to suggest rough _differentiae_ which mark off these values from one another. Legal values are social values which will be enforced, if need be, by the organized _physical_ force of the group, through the government. Moral values are social values which the group enforces by approbation and disapprobation, by cold shoulders and ostracism or by honor and praise. Economic values are values which the group enforces under a system of free enterprise, by means of profits and losses, by riches or bankruptcy. The group may, under a communistic or socialistic system, rely in whole or in part upon the machinery of the law; in which case economic values appear not in their own form as immediately guiding production, but as "presuppositions" of some of the legal values. The differentiation of these types of social value may also run in terms of their _functions_,[31] though it is not so easy to mark them off here, since their functions overlap. The function of economic values is to guide and control the economic activities of men, to send labor from one industry to another, to cause one sort of thing to be produced or another, to supply the motive force which _impels_ industry. Legal and moral values also directly affect industry, often working to check the results which the economic values alone would lead to--as when the law forbids the production and sale of liquor, or checks child labor, etc. The law, on the other hand, does not, primarily, in its influence on industry, seek _positively_ to determine its direction. The law forbids the production of liquor, but does not decree the production of bread. The law may seek to affect industry positively, by protective tariffs, for example, which aim at the building up of certain industries, but its effects are here indirect, reached through modifications in the economic values. Economic values, on the other hand, do not primarily aim at the regulation of the conduct of men outside the market place, or the shop or the farm, etc. Economic values are not primarily concerned with making men be good husbands or good neighbors, or brave soldiers. Economic values may be used, in part, for these purposes, as when a father-in-law uses his wealth as a lever to make his son-in-law behave--or, indeed, as a bait to get a son-in-law! It is hard to find a phase of social life which is not touched by all types of social values, but it is possible, roughly, to mark off those phases of social life which are subject to primary regulation by one or the other sort of social value. The differentiation is easier when we look at the social _institutions_ which have to do primarily with the one or the other sort of value. Courts and legislatures are easily marked off from stock exchanges and banking houses. There is not so clearly an institutional nucleus for moral values, since the church has lost its control over the moral situation.
