§ 1. The Law of the Increase of Production Depends on those of Three Elements—Labor. Capital, and Land.

Production is not a fixed but an increasing thing. When not kept back by bad institutions, or a low state of the arts of life, the produce of industry has usually tended to increase; stimulated not only by the desire of the producers to augment their means of consumption, but by the increasing number of the consumers.

We have seen that the essential requisites of production are three—labor, capital, and natural agents; the term capital including all external and physical requisites which are products of labor, the term natural agents all those which are not. The increase of production, therefore, depends on the properties of these elements. It is a result of the increase either of the elements themselves, or of their productiveness. We proceed to consider the three elements successively, with reference to this effect; or, in other words, the law of the increase of production, viewed in respect of its dependence, first on Labor, secondly on Capital, and lastly on Land.
