I might go on for pages, citing contradictory and self-contradictory definitions. But it would only weary the reader. It is unnecessary to multiply quotations. Those already given are sufficient to show how wide a difference exists as to the comprehension of the term capital. Anyone who wants further illustration of the “confusion worse confounded” which exists on this subject among the professors of political economy may find it in any library where the works of these professors are ranged side by side.
Now, it makes little difference what name we give to things, if when we use the name we always keep in view the same things and no others. But the difficulty arising in economic reasoning from these vague and varying definitions of capital is that it is only in the premises of reasoning that the term is used in the peculiar sense assigned by the definition, while in the practical conclusions that are reached it is always used, or at least it is always understood, in one general and definite sense. When, for instance, it is said that wages are drawn from capital, the word capital is understood in the same sense as when we speak of the scarcity or abundance, the increase or decrease, the destruction or increment, of capital—a commonly understood and definite sense which separates capital from the other factors of production, land and labor, and also separates it from like things used merely for gratification. In fact, most people understand well enough what capital is until they begin to define it, and I think their works will show that the economic writers who differ so widely in their definitions use the term in this commonly understood sense in all cases except in their definitions and the reasoning based on them.
This common sense of the term is that of wealth devoted to procuring more wealth. Dr. Adam Smith correctly expresses this common idea when he says: “That part of a man’s stock which he expects to afford him revenue is called his capital.” And the capital of a community is evidently the sum of such individual stocks, or that part of the aggregate stock which is expected to procure more wealth. This also is the derivative sense of the term. The word capital, as philologists trace it, comes down to us from a time when wealth was estimated in cattle, and a man’s income depended upon the number of head he could keep for their increase.
The difficulties which beset the use of the word capital, as an exact term, and which are even more strikingly exemplified in current political and social discussions than in the definitions of economic writers, arise from two facts—first, that certain classes of things, the possession of which to the individual is precisely equivalent to the possession of capital, are not part of the capital of the community; and, second, that things of the same kind may or may not be capital, according to the purpose to which they are devoted.
With a little care as to these points, there should be no difficulty in obtaining a sufficiently clear and fixed idea of what the term capital as generally used properly includes; such an idea as will enable us to say what things are capital and what are not, and to use the word without ambiguity or slip.
Land, labor, and capital are the three factors of production. If we remember that capital is thus a term used in contradistinction to land and labor, we at once see that nothing properly included under either one of these terms can be properly classed as capital. The term land necessarily includes, not merely the surface of the earth as distinguished from the water and the air, but the whole material universe outside of man himself, for it is only by having access to land, from which his very body is drawn, that man can come in contact with or use nature. The term land embraces, in short, all natural materials, forces, and opportunities, and, therefore, nothing that is freely supplied by nature can be properly classed as capital. A fertile field, a rich vein of ore, a falling stream which supplies power, may give to the possessor advantages equivalent to the possession of capital, but to class such things as capital would be to put an end to the distinction between land and capital, and, so far as they relate to each other, to make the two terms meaningless. The term labor, in like manner, includes all human exertion, and hence human powers whether natural or acquired can never properly be classed as capital. In common parlance we often speak of a man’s knowledge, skill, or industry as constituting his capital; but this is evidently a metaphorical use of language that must be eschewed in reasoning that aims at exactness. Superiority in such qualities may augment the income of an individual just as capital would, and an increase in the knowledge, skill, or industry of a community may have the same effect in increasing its production as would an increase of capital; but this effect is due to the increased power of labor and not to capital. Increased velocity may give to the impact of a cannon ball the same effect as increased weight, yet, nevertheless, weight is one thing and velocity another.
Thus we must exclude from the category of capital everything that may be included either as land or labor. Doing so, there remain only things which are neither land nor labor, but which have resulted from the union of these two original factors of production. Nothing can be properly capital that does not consist of these—that is to say, nothing can be capital that is not wealth.
But it is from ambiguities in the use of this inclusive term wealth that many of the ambiguities which beset the term capital are derived.
