It is fortunate for the modern world that there is a considerable number of persons who have time, inclination, and ability to inquire how human communities may best secure a prosperous existence and ultimate salvation from disasters or even annihilation. It is fortunate that the necessity is so widely felt of making such inquiries, and that there is so great an accumulation of facts, and of arguments based thereon, as to enable thinkers to arrive at a complete knowledge of the dangers which menace society, and of the best way of dealing with them. We greatly need light from men who are capable of giving answers to such questions as the following: “What should be the definite aim of all human societies? Whither tend the communities and nations now in existence? What are their special dangers, and how can they best be averted? What should be the true ideals of every people, so that they may be kept clearly in view and realised?”


The Use of Knowledge in Society

What is the problem we wish to solve when we try to construct a rational economic order? On certain familiar assumptions the answer is simple enough. If we possess all the relevant information, if we can start out from a given system of preferences, and if we command complete knowledge of available means, the problem which remains is purely one of logic. That is, the answer to the question of what is the best use of the available means is implicit in our assumptions. The conditions which the solution of this optimum problem must satisfy have been fully worked out and can be stated best in mathematical form: put at their briefest, they are that the marginal rates of substitution between any two commodities or factors must be the same in all their different uses.
