From the Arsenal of Marxism Value, Price and Profit By Karl Marx
Part 2
IV. Supply and Demand Our friend Weston accepts the Latin proverb that repetitio est mater studiorum, that is to say, that repetition is the mother of study, and consequently he repeated his original dogma again under the new form, that the contraction of currency, resulting from an enhancement of wages, would produce a diminution of capital, and so forth. Having already dealt with his currency crotchet, I consider it quite useless to enter upon the imaginary consequences he fancies to flow from his imaginary currency mishap. I shall proceed to at once reduce his one and the same dogma, repeated in so many different shapes, to its simplest theoretical form. The uncritical way in which he has treated his subject will become evident from one single remark. He pleads against a rise of wages or against high wages as the result of such a rise. Now, I ask him, What are high wages and what are low wages? Why constitute, for example, five shillings weekly low, and twenty shillings weekly high wages? If five is low as compared with twenty, twenty is still lower as compared with two hundred. If a man was to lecture on the thermometer, and commenced by declaiming on high and low degrees, he would impart no knowledge whatever. He must first tell me how the freezing-point is found out, and how the boiling-point, and how these standard points are settled by natural laws, not by the fancy of the sellers or makers of thermometers. Now, in regard to wages and profits, Citizen Weston has not only failed to deduce such standard points from economical laws, but he has not even felt the necessity to look after them. He satisfied himself with the acceptance of the popular slang terms of low and high as something having a fixed meaning, although it is self-evident that wages can only be said to be high or low as compared with a standard by which to measure their magnitudes. He will be unable to tell me why a certain amount of money is given for a certain amount of labor. If he should answer me, This was settled by the law of supply and demand, I should ask him, in the first instance, by what law supply and demand are themselves regulated. And such an answer would at once put him out of court. The relations between the supply and demand of labor undergo perpetual change, and with them the market prices of labor. If the demand overshoots the supply wages rise; if the supply overshoots the demand wages sink, although it might in such circumstances be necessary to test the real state of demand and supply by a strike, for example, or any other method. But if you accept supply and demand as the law regulating wages, it would be as childish as useless to declaim against a rise of wages, because, according to the supreme law you appeal to, a periodical rise of wages is quite as necessary and legitimate as a periodical fall of wages. If you do not accept supply and demand as the law regulating wages, I again repeat the question, why a certain amount of money is given for a certain amount of labor? But to consider matters more broadly: You would be altogether mistaken in fancying that the value of labor or any other commodity whatever is ultimately fixed by supply and demand. Supply and demand regulate nothing but the temporary fluctuations of market prices. They will explain to you why the market price of a commodity rises above or sinks below its value, but they can never account for the value itself. Suppose supply and demand to equilibrate, or, as the economists call it, to cover each other. Why, the very moment these opposite forces become equal they paralyze each other, and cease to work in the one or other direction. At the moment when supply and demand equilibrate each other, and therefore cease to act, the market price of a commodity coincides with its real value, with the standard price round which its market prices oscillate. In inquiring into the nature of that VALUE, we have therefore nothing at all to do with the temporary effects on market prices of supply and demand. The same holds true of wages and of the prices of all other commodities. V. Wages and Prices Reduced to their simplest theoretical expression, all our friends arguments resolve themselves into this one dogma: The prices of commodities are determined or regulated by wages. I might appeal to practical observation to bear witness against this antiquated and exploded fallacy. I might tell you that the English factory operatives, miners, shipbuilders, and so forth, whose labor is relatively high-priced, undersell by the cheapness of their produce all other nations; while the English agricultural laborer, for example, whose labor is relatively low-priced, is undersold by almost every other nation because of the dearness of his produce. By comparing article with article in the same country, and the commodities of different countries, I might show, apart from some exceptions more apparent than real, that on an average the high-priced labor produces the low-priced, and low priced labor produces the high-priced commodities. This, of course, would not prove that the high price of labor in the one, and its low price in the other instance, are the respective causes of those diametrically opposed effects, but at all events it would prove that the prices of commodities are not ruled by the prices of labor. However, it is quite superfluous for us to employ this empirical method. It might, perhaps, be denied that Citizen Weston has put forward the dogma: The prices of commodities are determined or regulated by wages. In point of fact, he has never formulated it. He said, on the contrary, that profit and rent also form constituent parts of the prices of commodities, because it is out of the prices of commodities that not only the working mans wages, but also the capitalists profits and the landlords rents must be paid. But how in his idea are prices formed? First by wages. Then an additional percentage is joined to the price on behalf of the capitalist, and another additional percentage on behalf of the landlord. Suppose the wages of the labor employed in the production of a commodity to be ten. If the rate of profit was 100 per cent, to the wages advanced the capitalist would add ten, and if the rate of rent was also 100 per cent upon the wages, there would be added ten more, and the aggregate price of the commodity would amount to thirty. But such a determination of prices would be simply their determination by wages. If wages in the above case rose to twenty, the price of the commodity would rise to sixty, and so forth. Consequently all the superannuated writers on political economy who propounded the dogma that wages regulate prices, have tried to prove it by treating profit and rent as mere additional percentages upon wages. None of them were, of course, able to reduce the limits of those percentages to any economic law. They seem, on the contrary, to think profits settled by tradition, custom, the will of the capitalist, or by some other equally arbitrary and inexplicable method. If they assert that they are settled by the competition between the capitalists, they say nothing. That competition is sure to equalize the different rates of profit in different trades, or reduce them to one average level, but it can never determine the level itself, or the general rate of profit. What do we mean by saying that the prices of the commodities are determined by wages? Wages being but a name for the price of labor, we mean that the prices of commodities are regulated by the price of labor. As price is exchangeable valueand in speaking of value I speak always of exchangeable valueis exchangeable value expressed in money, the proposition comes to this, that the value of commodities is determined by the value of labor, or that the value of labor is the general measure of value. But how, then, is the value of labor itself determined? Here we come to a standstill. Of course, to a standstill if we try reasoning logically. Yet the propounders of that doctrine make short work of logical scruples. Take our friend Weston, for example. First he told us that wages regulate the price of commodities and that consequently when wages rise prices must rise. Then he turned round to show us that a rise of wages will be no good because the prices of commodities had risen, and because wages were indeed measured by the prices of the commodities upon which they are spent. Thus we begin by saying that the value of labor determines the value of commodities, and we wind up by saying that the value of commodities determines the value of labor. Thus we move to and fro in the most vicious circle, and arrive at no conclusion at all. On the whole, it is evident that by making the value of one commodity, say labor, corn, or any other commodity, the general measure and regulator of value, we only shift the difficulty, since we determine one value by another, which on its side wants to be determined. The dogma that wages determine the price of commodities, expressed in its most abstract terms, comes to this, that value is determined by value, and this tautology means that, in fact, we know nothing at all about value. Accepting this premise, all reasoning about the general laws of political economy turns into mere twaddle. It was, therefore, the great merit of Ricardo that in his work on the principles of political economy, published in 1817, he fundamentally destroyed the old popular, and worn-out fallacy that wages determine prices, a fallacy which Adam Smith and his French predecessors had spurned in the really scientific parts of their researches, but which they reproduced in their more exoterical and vulgarizing chapters. VI. Value and Labor Citizens, I have now arrived at a point where I must enter upon the real development of the question. I cannot promise to do this in a very satisfactory way, because to do so I should be obliged to go over the whole field of political economy. I can, as the French would say, but effleurer la question, touch upon the main points. The first question we have to put is: What is the value of a commodity? How is it determined? At first sight it would seem that the value of a commodity is a thing quite relative, and not to be settled without considering one commodity in its relations to all other commodities. In fact, in speaking of the value, the value in exchange of a commodity, we mean the proportional quantities in which it exchanges with all other commodities. But then arises the question: How are the proportions in which commodities exchange with each other regulated? We know from experience that these proportions vary infinitely. Taking one single commodity, wheat, for instance, we shall find that a quarter of wheat exchanges in almost countless variations of proportion with different commodities. Yet, its value remaining always the same, whether expressed in silk, gold, or any other commodity, it must be something distinct from, and independent of, these different rates of exchange with different articles. It must be possible to express, in a very different form, these various equations with various commodities. Besides, if I say a quarter of wheat exchanges with iron in a certain proportion, or the value of a quarter of wheat is expressed in a certain amount of iron, I say that the value of wheat and its equivalent in iron are equal to some third thing, which is neither wheat nor iron, because I suppose them to express the same magnitude in two different shapes. Either of them, the wheat or the iron, must, therefore, independently of the other, be reducible to this third thing which is their common measure. To elucidate this point I shall recur to a very simple geometrical illustration. In comparing the areas of triangles of all possible forms and magnitudes, or comparing triangles with rectangles, or any other rectilinear figure, how do we proceed? We reduce the area of any triangle whatever to an expression quite different from its visible form. Having found from the nature of the triangle that its area is equal to half the product of its base by its height, we can then compare the different values of all sorts of triangles, and of all rectilinear figures whatever, because all of them may be resolved into a certain number of triangles. The same mode of procedure must obtain with the values of commodities. We must be able to reduce all of them to an expression common to all, and distinguishing them only by the proportions in which they contain that identical measure. As the exchangeable values of commodities are only social functions of those things, and have nothing at all to do with the natural qualities, we must first ask, What is the common social substance of all commodities? It is labor. To produce a commodity a certain amount of labor must be bestowed upon it, or worked up in it. And I say not only labor, but social labor. A man who produces an article for his own immediate use, to consume it himself, creates a product, but not a commodity. As a self-sustaining producer he has nothing to do with society. But to produce a commodity, a man must not only produce an article satisfying some social want, but his labor itself must form part and parcel of the total sum of labor expended by society. It must be subordinate to the division of labor within society. It is nothing without the other divisions of labor, and on its part is required to integrate them. If we consider commodities as values, we consider them exclusively under the single aspect of realized, fixed, or, if you like, crystallized social labor. In this respect they can differ only by representing greater or smaller quantities of labor, as, for example, a greater amount of labor may be worked up in a silken handkerchief than in a brick. But how does one measure quantities of labor? By the time the labor lasts, in measuring the labor by the hour, the day, etc. Of course, to apply this measure, all sorts of labor are reduced to average or simple labor as their unit. We arrive, therefore, at this conclusion. A commodity has a value, because it is a crystallization of social labor. The greatness of its value, or its relative value, depends upon the greater or less amount of that social substance contained in it; that is to say, on the relative mass of labor necessary for its production. The relative values of commodities are, therefore, determined by the respective quantities or amounts of labor, worked up, realized, fixed in them. The correlative quantities of commodities which can be produced in the same time of labor are equal. Or the value of one commodity is to the value of another commodity as the quantity of labor fixed in the one is to the quantity of labor fixed in the other. I suspect that many of you will ask, Does then, indeed, there exist such a vast, or any difference whatever, between determining the values of commodities by wages, and determining them by the relative quantities of labor necessary for their production? You must, however, be aware that the reward for labor, and quantity of labor, are quite disparate things. Suppose, for example, equal quantities of labor to be fixed in one quarter of wheat and once ounce of gold. I resort to the example because it was used by Benjamin Franklin in his first Essay published in 1721, and entitled a modest enquiry into the nature and necessity of a paper currency, where he, one of the first, hit upon the true nature of value. Well. We suppose, then, that one quarter of wheat and one ounce of gold are equal values or equivalents, because they are crystallizations of equal amounts of average labor, of so many days or so many weeks labor respectively fixed in them. In thus determining the relative values of gold and corn, do we refer in any way whatever to the wages of the agricultural laborer and the miner? Not a bit. We leave it quite indeterminate how their days or their weeks labor was paid, or even whether wages labor was employed at all. If it was, wages may have been very unequal. The laborer whose labor is realized in the quarter of wheat may receive two bushels only, and the laborer employed in mining may receive one-half of the ounce of gold. Or, supposing their wages to be equal, they may deviate in all possible proportions from the values of the commodities produced by them. They may amount to one-fourth, one-fifth, or any other proportional part of the one-quarter of corn or the one ounce of gold. Their wages can, of course, not exceed, not be more than the values of the commodities they produced, by they can be less in every possible degree. Their wages will be limited by the values of the products, but the values of their products will not be limited by the wages. And above all, the values, the relative values of corn and gold, for example, will have been settled without any regard whatever to the value of the labor employed, that is to say, to wages. To determine the values of commodities by the relative quantities of labor fixed in them, is, therefore, a thing quite different from the tautological method of determining the values of commodities by the value of labor, or by wages. This point, however, will be further elucidated in the progress of our inquiry. In calculating the exchangeable value of a commodity we must add to the quantity of labor previously worked up in the raw material of the commodity, and the labor bestowed on the implements, tools, machinery, and buildings, with which such labor is assisted. For example, the value of a certain amount of cotton yarn is the crystallization of the quantity of labor added to the cotton during the spinning process, the quantity of labor previously realized in the cotton itself, the quantity of labor realized in the coal, oil, and other auxiliary substances used, the quantity of labor fixed in the steam-engine, the spindles, the factory building, and so forth Instruments of production properly so-called, such as tools, machinery, buildings, serve again and again for longer or shorter period during repeated processes of production. If they were used up at once, like the raw material, their whole value would at once be transferred to the commodities they assist in producing. But as a spindle, for example, is but gradually used up, an average calculation is made, based upon the average time it lasts, and its average waste or wear and tear during a certain period, say a day. In this way we calculate how much of the value of the spindle is transferred to the yarn daily spin, and how much, therefore, of the total amount of labor realized in a pound of yarn, for example, is due to the quantity of labor previously realized in the spindle. For our present purpose it is not necessary to dwell any longer upon this point. It might seem that if the value of a commodity is determined by the quantity of labor bestowed upon its production, the lazier a man, or the clumsier a man, the more valuable his commodity, because the greater the time of labor required for finishing the commodity. This, however, would be a sad mistake. You will recollect that I used the word social labor, and many points are involved in this qualification of social. In saying that the value of a commodity is determined by the quantity of labor worked up or crystallized in it, we mean the quantity of labor necessary for its production in a given state of society, under certain social average conditions of production, with a given social average intensity, and average skill of the labor employed. When, in England, the power-loom came to compete with the hand-loom, only half the former time of labor was wanted to convert a given amount of yarn into a yard of cotton or cloth. The poor hand-loom weaver now worked seventeen or eighteen hours daily, instead of the nine or the hours he had worked before. Still the product of twenty hours of his labor represented now only ten social hours of labor, or ten hours of labor socially necessary for the conversion of a certain amount of yarn into textile stuffs. His product of twenty hours had, therefore, no more value than his former product of ten hours. If then the quantity of socially necessary labor realized in commodities regulates their exchangeable values, every increase in the quantity of labor wanted for the production of a commodity must augment its value, as every diminution must lower it. If the respective quantities of labor necessary for the production of the respective commodities remained constant, their relative values also would be constant. But such is not the case. The quantity of labor necessary for the production of a commodity changes continuously with the changes in the productive powers of labor, the more produce is finished in a given time of labor; and the smaller the productive powers of labor, the less produce is finished in the same time. If, for example, in the progress of population it should become necessary to cultivate less fertile soils, the same amount of produce would be only attainable by a greater amount of labor spent, and the value of agricultural produce would consequently rise. On the other hand, if, with the modern means of production, a single spinner converts into yarn, during one working day, many thousand times the amount of cotton which he could have spun during the same time with the spinning wheel, it is evident that every single pound of cotton will absorb many thousand times less of spinning labor than it did before, and consequently, the value added by spinning to every single pound of cotton will be a thousand times less than before. The value of yarn will sink accordingly. Apart from the different natural energies and acquired working abilities of different peoples, the productive powers of labor must principally depend: Firstly. Upon the natural conditions of labor, such as fertility of soil, mines, and so forth. Secondly. Upon the progressive improvement of the social powers of labor, such as are derived from production on a grand scale, concentration of capital and combination of labor, subdivision of labor, machinery, improved methods, appliance of chemical and other natural agencies, shortening of time and space by means of communication and transport, and every other contrivance by which science presses natural agencies into the service of labor, and by which the social or co-operative character of labor is developed. The greater the productive powers of labor, the less labor is bestowed upon a given amount of produce; hence the smaller the value of the produce. The smaller the productive powers of labor, the more labor is bestowed upon the same amount of produce; hence the greater its value. As a general law we may, therefore, set it down that: The values of commodities are directly as the times of labor employed in their production, and are inversely as the productive powers of the labor employed. Having till now only spoken of value, I shall add a few words about price, which is a peculiar from assumed by value. Price, taken by itself, is nothing but the monetary expression of value. The values of all commodities of the country, for example, are expressed in gold prices, while on the Continent they are mainly expressed in silver prices. The value of gold or silver, like that of all other commodities is regulated by the quantity of labor necessary for getting them. You exchange a certain amount of your national products, in which a certain amount of your national labor is crystallized, for the produce of the gold and silver producing countries, in which a certain quantity of their labor is crystallized. It is in this way, in fact by barter, that you learn to express in gold and silver the values of all commodities, that is the respective quantities of labor bestowed upon them. Looking somewhat closer into the monetary expression of value, or what comes to the same, the conversion of value into price, you will find that it is a process by which you give to the values of all commodities an independent and homogeneous form, or by which you express them as quantities of equal social labor. So far as it is but the monetary expression of value, price has been called natural price by Adam Smith, prix necessaire by the French physiocrats. What then is the relation between value and market prices, or between natural prices and market prices? You all know that the market price is the same for all commodities of the same kind, however the conditions of production may differ for the individual producers. The market price expresses only the average amount of social labor necessary, under the average conditions of production, to supply the market with a certain mass of a certain article. It is calculated upon the whole lot of a commodity of a certain description. So far the market price of a commodity coincides with its value. On the other hand, the oscillations of market prices, rising now over, sinking now under the value or natural price, depend upon the fluctuations of supply and demand. The deviations of market prices from values are continual, but as Adam Smith says: The natural price is the central price to which the prices of commodities are continually gravitating. Different accidents may sometimes keep them suspended a good deal above it, and sometimes force them down even somewhat below it. But whatever may be the obstacles which hinder them from settling in this center of repose and continuance, they are constantly tending towards it. I cannot now sift this matter. It suffices to say the if supply and demand equilibrate each other, the market prices of commodities will correspond with their natural prices, that is to say with their values, as determined by the respective quantities of labor required for their production. But supply and demand must constantly tend to equilibrate each other, although they do so only by compensating one fluctuation by another, a rise by a fall, and vice versa. If instead of considering only the daily fluctuations you analyze the movement of market prices for longer periods, as Mr. Tooke, for example, has done in his History of Prices, you will find that the fluctuations of market prices, their deviations from values, their ups and downs, paralyze and compensate each other; so that apart from the effect of monopolies and some other modifications I must now pass by, all descriptions of commodities are, on average, sold at their respective values or natural prices. The average periods during which the fluctuations of market prices compensate each other are different for different kinds of commodities, because with one kind it is easier to adapt supply to demand than with the other. If the, speaking broadly, and embracing somewhat longer periods, all descriptions of commodities sell at their respective values, it is nonsense to suppose that profit, not in individual cases; but that the constant and usual profits of different trades spring from the prices of commodities, or selling them at a price over and above their value. The absurdity of this notion becomes evident if it is generalized. What a man would constantly win as a seller he would constantly lose as a purchaser. It would not do to say that there are men who are buyers without being sellers, or consumers without being without being producers. What these people pay to the producers, they must first get from them for nothing. If a man first takes your money and afterwards returns that money in buying your commodities, you will never enrich yourselves by selling your commodities too dear to that same man. This sort of transaction might diminish a loss, but would never help in realizing a profit. To explain, therefore, the general nature of profits, you must start from the theorem that, on an average, commodities are sold at their real values, and that profits are derived from selling them at their values, that is, in proportion to the quantity of labor realized in them. If you cannot explain profit upon this supposition, you cannot explain it at all. This seems paradox and contrary to every-day observation. It is also paradox that the earth moves round the sun, and that water consists of two highly inflammable gases. Scientific truth is always paradox, if judged by every-day experience, which catches only the delusive appearance of things. VII. Labor Power Having now, as far as it could be done in such a cursory manner, analyzed the nature of value, of the value of any commodity whatever, we must turn our attention to the specific value of labor. And here, again, I must startle you by a seeming paradox. All of you feel sure that what they daily sell is their Labor; that, therefore, Labor has a Price, and that, the price of a commodity being only the monetary expression of its value, there must certainly exist such a thing as the value of labor. However, there exists no such thing as the value of labor in the common acceptance of the word. We have seen that the amount of necessary labor crystallized in a commodity constitutes its value. Now, applying this notion of value, how could we define, say, the value of a ten hours working day? How much labor is contained in that day? Ten hours labor. To say that the value of a ten hours working day is equal to ten hours labor, or the quantity of labor contained in it, would be a tautological and, moreover, a nonsensical expression. Of course, having once found out the true but hidden sense of the expression value of labor, we shall be able to interpret this irrational, and seemingly impossible application of value, in the same way that, having once made sure of the real movement of the celestial bodies, we shall be able to explain their apparent or merely phenomenal movements. What the working man sells is not directly his labor, but his laboring power, the temporary disposal of which he makes over to the capitalist. This is so much the case that I do not know whether by the English Laws, but certainly by some Continental Laws, the maximum time is fixed for which a man is allowed to sell his laboring power. If allowed to do so for any indefinite period whatever, slavery would be immediately restored. Such a sale, if it comprised his lifetime, for example, would make him at once the lifelong slave of his employer. One of the oldest economists and most original philosophers of EnglandThomas Hobbeshas already, in his Leviathan, instinctively hit upon this point overlooked by all his successors. He says: the value or worth of a man is, as in all other things, his price: that is so much as would be given for the use of his power. Proceeding from this basis, we shall be able to determine the value of labor as that of all other commodities. But before doing so, we might ask, how does this strange phenomenon arise, that we find on the market a set of buyers, possessed of land, machinery, raw material, and the means of subsistence, all of them, save land in its crude state, the products of labor, and on the other hand, a set of sellers who have nothing to sell except their laboring power, their working arms and brains? That the one set buys continually in order to make a profit and enrich themselves, while the other set continually sells in order to earn their livelihood? The inquiry into this question would be an inquiry into what the economists call previous or original accumulation, but which ought to be called orginal expropriation. We should find that this so-called original accumulation means nothing but a series of historical processes, resulting in a decomposition of the original union existing between the laboring Man and his Instruments of Labor. Such an inquiry, however, lies beyond the pale of my present subject. The separation between the Man of Labor and the Instruments of Labor once established, such a state of things will maintain itself and reproduce itself upon a constantly increasing scale, until a new and fundamental revolution in the mode of production should again overturn it, and restore the original union in a new historical form. What, then, is the value of laboring power? Like that of every other commodity, its value is determined by the quantity of labor necessary to produce it. The laboring power of a man exists only in his living individuality. A certain mass of necessaries must be consumed by a man to grow up and maintain his life. But the man, like the machine, will wear out, and must be replaced by another man. Beside the mass of necessaries required for his own maintenance, he wants another amount of necessaries to bring up a certain quota of children that are to replace him on the labor market and to perpetuate the race of laborers. Moreover, to develop his laboring power, and acquire a given skill, another amount of values must be spent. For our purpose it suffices to consider only average labor, the costs of whose education and development are vanishing magnitudes. Still I must seize upon this occasion to state that, as the costs of producing laboring powers of different quality differ, so must differ the values of the laboring powers employed in different trades. The cry for an equality of wages rests, therefore, upon a mistake, is an inane wish never to be fulfilled. It is an offspring of that false and superficial radicalism that accepts premises and tries to evade conclusions. Upon the basis of the wages system the value of laboring power is settled like that of every other commodity; and as different kinds of laboring power have different values, or require different quantities of labor for their production, they must fetch different prices in the labor market. To clamor for equal or even equitable retribution on the basis of the wages system is the same as to clamor for freedom on the basis of the slavery system. What you think just or equitable is out of the question. The question is: What is necessary and unavoidable with a given system of production? After what has been said, it will be seen that the value of laboring power is determined by the value of the necessaries required to produce, develop, maintain, and perpetuate the laboring power. VIII. Production of Surplus Value Now suppose that the average amount of the daily necessaries of a laboring man require six hours of average labor for their production. Suppose, moreover, six hours of average labor to be also realized in a quantity of gold equal to 3s. Then 3s. would be the price, or the monetary expression of the daily value of that mans laboring power. If he worked daily six hours he would daily produce a value sufficient to buy the average amount of his daily necessaries, or to maintain himself as a laboring man. But our man is a wages laborer. He must, therefore, sell his laboring power to a capitalist. If he sells it at 3s. daily, or 18s. weekly, he sells it at its value. Suppose him to be a spinner. If he works six hours daily he will add to the cotton a value of 3s. daily. This value, daily added by him, would be an exact equivalent for the wages, or the price of his laboring power, received daily. But in that case no surplus value or surplus produce whatever would go to the capitalist. Here, then, we come to the rub. In buying the laboring power of the workman, and paying its value, the capitalist, like every other purchaser, has acquired the right to consume or use the commodity bought. You consume or use the laboring power of a man by making him work, as you consume or use a machine by making it run. By buying the daily or weekly value of the laboring power of the workman, the capitalist has, therefore, acquired the right to use or make that laboring power during the whole day or week. The working day or the working week has, of course, certain limits, but those we shall afterwards look more closely at. For the present I want to turn your attention to one decisive point. The value of the laboring power is determined by the quantity of labor necessary to maintain or reproduce it, but the use of that laboring power is only limited by the active energies and physical strength of the laborer. The daily or weekly value of the laboring power is quite distinct from the daily or weekly exercise of that power, the same as the food a horse wants and the time it can carry the horseman are quite distinct. The quantity of labor by which the value of the workmans laboring power is limited forms by no means a limit to the quantity of labor which his laboring power is apt to perform. Take the example of our spinner. We have seen that, to daily reproduce his laboring power, he must daily reproduce a value of three shillings, which he will do by working six hours daily. But this does not disable him from working ten or twelve or more hours a day. But by paying the daily or weekly value of the spinners laboring power the capitalist has acquired the right of using that laboring power during the whole day or week. He will, therefore, make him work say, daily, twelve hours. Over and above the six hours required to replace his wages, or the value of his laboring power, he will, therefore, have to work six other hours, which I shall call hours of surplus labor, which surplus labor will realize itself in a surplus value and a surplus produce. If our spinner, for example, by his daily labor of six hours, added three shillings value to the cotton, a value forming an exact equivalent to his wages, he will, in twelve hours, add six shillings worth to the cotton, and produce a proportional surplus of yarn. As he has sold his laboring power to the capitalist, the whole value of produce created by him belongs to the capitalist, the owner pro tem. of his laboring power. By advancing three shillings, the capitalist will, therefore, realize a value of six shillings, because, advancing a value in which six hours of labor are crystallized, he will receive in return a value in which twelve hours of labor are crystalized. By repeating this same process daily, the capitalist will daily advance three shillings and daily pocket six shillings, one half of which will go to pay wages anew, and the other half of which will form surplus value, for which the capitalist pays no equivalent. It is this sort of exchange between capital and labor upon which capitalistic production, or the wages system, is founded, and which must constantly result in reproducing the working man as a working man, and the capitalist as a capitalist. The rate of surplus value, all other circumstances remaining the same, will depend on the proportion between that part of the working day necessary to reproduce the value of the laboring power and the surplus time or surplus labor performed for the capitalist. It will, therefore, depend on the ratio in which the working day is prolonged over and above that extent, by working which the working man would only reproduce the value of his laboring power, or replace his wages.
