ABSTRACT
Economics is a search for the method of getting the most out of things. But this assignment taken literally would sink it in a morass of detailed technology. Economics was brought to a halt by having arrived at a terminus, the end of a road. Subjective marginalism, conferring determinacy on the conception of general equilibrium, brought one system of economic theory to perfection. In mathematics the analytical method consists in supposing the problem solved and considering what must be the characteristics of the solution. For practical purposes, in a sense, the procedure thus starts from the wrong end. The formal notion of pre-reconciled choice solves, within a highly artificial and abstract frame, the problem of how men can make their choices of action in full knowledge of each other's simultaneous choices. Such a solution is necessary to the notion of strict rationality, the exercise of reason upon complete relevant information, since the latter must include the intended actions of others.
