Finally, production is not only of a special kind. It is always a certain body politic, a social personality that is engaged on a larger or smaller aggregate of branches of production. The connection between the real process and its scientific presentation also falls outside of the scope of this treatise. [We must thus distinguish between] production in general, special branches of production and production as a whole. It is the fashion with economists to open their works with a general introduction, which is entitled “production” (see, e. g., John Stuart Mill) and deals with the general “requisites of production.” This general introductory part treats or is supposed to treat: 1. Of the conditions without which production is impossible, i. e., of the most essential conditions of production. As a matter of fact, however, it dwindles down, as we shall see, to a few very simple definitions, which flatten out into shallow tautologies; 2. Of conditions which further production more or less, as, e. g., Adam Smith’s [discussion of] a progressive and stagnant state of society. In order to give scientific value to what serves with him as a mere summary, it would be necessary to study the _degree of productivity_ by periods in the development of individual nations; such a study falls outside of the scope of the present subject, and in so far as it does belong here is to be brought out in connection with the discussion of competition, accumulation, etc. The commonly accepted view of the matter gives a general answer to the effect that an industrial nation is at the height of its production at the moment when it reaches its historical climax in all respects. Or, that certain races, climates, natural conditions, such as distance from the sea, fertility of the soil, etc., are more favorable to production than others. That again comes down to the tautology that the facility of creating wealth depends on the extent to which its elements are present both subjectively and objectively. As a matter of fact a nation is at its industrial height so long as its main object is not gain, but the process of gaining. In that respect the Yankees stand above the English.
