OF THE REQUISITES OF PRODUCTION.
s 1. The requisites of production are two: labor, and appropriate natural objects.
Labor is either bodily or mental ; or, to express the distinction more comprehensively, either muscular or nervous ; and it is necessary to include in the idea, not solely the exertion itself, but all feelings of a disagreeable kind, all bodily inconvenience or mental annoyance, connected with the employment of one's thoughts, or muscles, or both, in a particular occupation. Of the other requisite-appropriate natural objects—it is to be remarked, that some objects exist or grow up spontaneously, of a kind suited to the supply of human wants. There are caves and hollow trees capable of affording shelter; fruit, roots, wild honey, and other natural products on which human life can be supported; but even here a considerable quantity of labor is generally required, not for the purpose of creating, but of finding and appropriating them. In all but these few and (except in the very commencement of human society) unimportant cases, the objects supplied by nature are only instrumental VOL. I.
to human wants, after having undergone some degree of transformation by human exertion. Even the wild animals of the forest and of the sea, from which the hunting and fishing tribes derive their sustenance—although the labor of which they are the subject is chiefly that required for appropriating them-must yet, before they are used as food, be killed, divided into fragments, and subjected in almost all cases to some process of cookery, which are operations requiring a certain degree of human labor. The amount of transformation which natural substances undergo before being brought into the shape in which they are directly applied to human use, varies from this or a still less degree of alteration in the nature and appearance of the object, to a change so total that no trace is perceptible of the original shape and structure. There is little resemblance between a piece of a mineral substance found in the earth, and a plough, an axe, or a saw. There is less resemblance between porcelain and the decomposing granite of which it is made, or between sand mixed with sea-weed and glass. The difference is greater still between the fleece of a sheep, or a handful of cotton seeds, and a web of muslin or broadcloth ; and the sheep and seeds themselves are not spontaneous growths, but results of previous labor and care. In these several cases, the ultimate product is so extensively dissimilar to the substance supplied by nature, that in the custom of language nature is represented as only furnishing materials.
Nature, however, does more than supply materials; she also supplies powers. The matter of the globe is not an inert recipient of forms and properties impressed by human hands; it has active energies by which it cooperates with, and may even be used as a substitute for, labor. In the early ages, men converted their corn into four by pounding it between two stones; they next hit on a contrivance which enabled them, by turning a handle, to make one of the stones revolve upon the other; and this process, a little improved, is still the common practice of the East. The muscular exertion, however, which it required, was very severe and exhausting, insomuch that it was often selected as a punishment for slaves who had offended their masters. When the time came at which the labor and sufferings of slaves were thought worth economizing, the greater part of this bodily exertion was rendered unnecessary, by contriving that the upper stone should be made to revolve upon the lower, not by human strength, but by the force of the wind or the falling water. In this case, natural agents, the wind or the gravitation of the water, are made to do a portion of the work previously done by labor.
2. Cases like this, in which a certain amount of labor has been dispensed with, its work being devolved upon some natural agent, are apt to suggest an erroneous notion of the comparative functions of labor and natural powers; as if the co-operation of those powers with human industry were limited to the cases in which they are made to perform what would otherwise be done by labor; as if, in the case of things made (as the phrase is) by hand, nature only furnished passive materials. This is an illusion. The powers of nature are as actively operative in the one case as in the other. A workman takes a stalk of the flax or hemp plant, splits it into separate fibres, twines together several of these fibres with his fingers, aided by a simple instrument called a spindle; having thus formed a thread, he lays many such · threads side by side, and places other similar threads directly across them, so that each passes alternately over and under those which are at right angles to it; this part of the process being facilitated by an instrument called a shuttle. He has now produced a web of cloth, either linen or sackcloth according to the material. He is said to have done this by hand, no natural force being supposed to have acted in concert with him. But by what force is each step of this operation rendered possible, and the web, when produced,
held together? Is it not by the tenacity, or force of cohesion, of the fibres? which is one of the forces in nature, and which we can measure exactly against other mechanical forces, and ascertain how much of any of them it suffices to neutralize or counterbalance.
If we examine any other case of what is called the action of man upon nature, we shall find in like manner that the powers of nature, or, in other words, the properties of matter, do all the work, when once objects are put into the right position. This one operation, of putting things into fit places for being acted upon by their own internal forces, and by those residing in other natural objects, is all that man does, or can do, with matter. He only moves one thing to or from another. He moves a seed into the ground; and the natural forces of vegetation produce in succession a root, a stem, leaves, flowers, and fruit. He moves an axe through a tree, and it falls by the natural force of gravitation; he moves a saw through it, in a particular manner, and the physical properties by which a softer substance gives way before a harder, make it separate into planks, which he arranges in certain positions, with some adhesive matter between them, and produces a table or a house. He moves a spark to fuel, and it ignites, and by the force of combustion it cooks the food, melts or softens the iron, converts into beer or sugar the malt or cane juice, which he has previously moved to the spot. He has no other means of acting on matter than by moving it. Motion, and resistance to motion, are the only things which his muscles are constructed for. By muscular contraction he can create a pressure on an outward object, which, if sufficiently powerful, will set it in motion, or if it be already moving, will check or modify or altogether arrest its motion, and he can do no more. But this is enough to have given him all the command which mankind have acquired over natural forces immeasurably more powerful than themselves; a command
