Right here we may see clearly the main objection to the term, "Labor," as commonly used, and the bad fallacy to which it gives birth. "Labor" is indeed in form and origin an _abstract_ term as much as "service" is, with this difference, that the word "service" radically implies the person serving and another person served at the same instant; but the term "Labor" has long been taking on itself in the mouths of men a _concrete_ meaning, as if it might be something separate from the laborers, as in the common phrase "Labor and Capital," which has already done a world of mischief and is likely to do a good deal more, because it seems to imply, that the two are alike in independent self-existence, and that they stand over against each other on equal terms for a fair bargain or for a free fight. This is not the case, as we shall see more fully later; since capital is something separable from the capitalist, always a commodity or a claim, always transferable, always valuable or else it will not be "Capital." Some of the German economists, and particularly John Conrad of Halle, have avoided this difficulty by a clean nomenclature. They say "_Labor-givers_" and "_Labor-takers_," instead of Laborers and Capitalists, and especially instead of "Labor and Capital," thus emphasizing the personal element in both terms, and also leaving themselves free to define and use the term "Capital" as distinct from any particular capitalist, while the term "Labor" cannot be defined and used as distinct from any given laborer. This precise point, though probably new, is of very considerable consequence in the true doctrine of Wages. We are compelled by the exigencies of the English language and the still stronger fetters of economical custom to continue to use the terms "Labor" and "Laborers" in their technical sense, and in connection with the scientific terms "Capital" and "Capitalist"; but we shall always use each of these words in the same meaning, and free them as far as possible from the fungous accretions that have fastened upon them in the course of time. _Personal effort of any kind put forth for another in view of a return-service and for the sake of it is labor._ _Laborers are persons rendering their peculiar services to other persons for a commercial reward._ _The valuable received by a laborer for his service rendered is Wages._
