2. _Economic production is the origin, or genesis, of value finding its source either in objective things or in services._ The writers of fifty years ago defined economic production as the application of labor to the creation of wealth. But as there are two factors in production, man and material things, so there are two productive sources of value. In some cases the origin of value is attributable to man's action; in other cases scarce uses arise in objective things without man's action. Broad as is this definition of production, it does not include the enjoyment of free goods, as in the case of the care-free darky basking in the sun. Anything that, causing a feeling of greater importance to attach to a thing, changes it from a free good to a scarce good or makes it more scarce, is a cause of its value. A large rainfall causing a greater crop of grain may be thought of as producing utility. The regular surplus of value attributable to the waterfall or to the railroad, is the product of the material services of wealth. Production through human action is the more obvious and is the more usually thought of; the part of material agents must be recognized if the fallacies of the labor theory of value are to be avoided.

In one thing more land and machinery are used, in another more labor is used. But either of these two great classes of agents may touch the vanishing point in the production of value. While it is true that man's part is the most striking aspect of production, yet there may be value without labor. The study of rent puts this abstractly, but in a clear light. In actual life, however, a part of the value is usually attributable to rent, a part to labor. [Sidenote: Value of labor derived from its products]
