D.1. The Functions of an Economist in a Society: An economist fills the gap of Rationality in his or her society (From 1.6.1, and 1.5.6).
E.1. Our society evolves through two contradictions. On the one hand, the means are not fully permissive of the simultaneous gratification of all the ends, and on the other hand, our ends are always contradictory. Faced with such conflicts, a society, if it is willing to progress, requires Rationality as described in 1.6.1. And it is the task of an Economic Analyst to equip his society with the needed Rationality. It is an economic analyst who studies the implications of scarce substitutable means for the multiple ends, identifies the contradictions therein, and informs the society of the costs, or the sacrifices necessitated by reason.
In studying the implications of scarce means and multiple ends, it is natural that he or she discovers the most efficient long run path to achieve the conflicting ends. And due to 1.4.3, acting as trustee of the society, it is logical necessity that he or she informs the society of these paths too. In so doing, an economists acts as the Rational Unit of the society. And since, from 1.5.4, economics is but a logic, an economist is only a logician of a society willing to progress through the manifold contradictions of scarce means and conflicting ends. An economist is only of the service to a society striving to progress, and regardless of how scarce, how impermissive its means, all its ends ..... perpetually multiple, always immutable!!!!
