To return to the main drift of the argument. The pecuniary employments have to do with wealth in point of ownership, with market values, with transactions of exchange, purchase and sale, bargaining for the purpose of pecuniary gain. These employments make up the characteristic occupations of business men, and the gains of business are derived from successful endeavors of the pecuniary kind. These business employments are the characteristic activity (constitute the "function") of what are in theory called undertakers. The dispositions which undertakers, _qua_ business men, make are pecuniary dispositions--whatever industrial sequel they may or may not have--and are carried out with a view to pecuniary gain. The wealth of which they have the discretionary disposal may or may not be in the form of "production goods"; but in whatever form the wealth in question is conceived to exist, it is handled by the undertakers in terms of values and is disposed of by them in the pecuniary respect. When, as may happen, the undertaker steps down from the pecuniary plane and directs the mechanical handling and functioning of "production goods," he becomes for the time a foreman. The undertaker, if his business venture is of the industrial kind, of course takes cognizance of the aptness of a given industrial method or process for his purpose, and he has to choose between different industrial processes in which to invest his values; but his work as undertaker, simply, is the investment and shifting of the values under his hand from the less to the more gainful point of investment. When the investment takes the form of material means of industry, or industrial plant, the sequel of a given business transaction is commonly some particular use of such means; and when such industrial use follows, it commonly takes place at the hands of other men than the undertaker, although it takes place within limits imposed by the pecuniary exigencies of which the undertaker takes cognizance. Wealth turned to account in the way of investment or business management may or may not, in consequence, be turned to account, materially, for industrial effect. Wealth, values, so employed for pecuniary ends is capital in the business sense of the word.[10] Wealth, material means of industry, physically employed for industrial ends is capital in the industrial sense. Theory, therefore, would require that care be taken to distinguish between capital as a pecuniary category, and capital as an industrial category, if the term capital is retained to cover the two concepts.[11] The distinction here made substantially coincides with a distinction which many late writers have arrived at from a different point of approach and have, with varying success, made use of under different terms.[12]
