The first of the two debates contained in this volume—between Andrew Kliman and Alan Freeman on one hand, and Simon Mohun and Roberto Veneziani on the other—initially focused on a logical issue: is it possible to deduce Marx’s conclusion in a logically valid way? Which, if any, of the different interpretations of his value theory succeeds in doing so? In the course of the debate, however, issues of pluralism, truth, and scientificity increasingly assumed center stage. As I shall document below, behavior that I regard as suppressive and contrary to scientific norms was engaged in with some frequency, and I personally suffered from it. Let me make clear from the outset that I was not personally engaged in this debate. For that reason, and because I have set aside my theoretical commitments as much as possible when drawing conclusions about the debate, this introduction to it is reasonably objective. Although some of my conclusions may unfortunately seem a bit harsh, I think other disinterested but knowledgeable parties would draw similar conclusions, and I certainly do not mean to be disrespectful of any individual. This introduction criticizes certain practices and texts, not authors as persons. MARX’S THEORY OF PROFIT A main purpose of volume 1 of Marx’s Capital is to reveal the shocking secret of where profit (surplus-value) comes from. Although he thought that the classical economists Adam Smith and David Ricardo had come close to having solved the problem, Marx regarded their efforts as ultimately unsuccessful. He first argued that—in the economy as a whole—profit cannot be the result of cheating, buying things for less than they are worth or selling them for more than they are worth. Particular capitalists can get profit in this way, but only at the expense of other capitalists. One’s gain is the other’s loss. “The capitalist class of a given country, taken as a whole, cannot defraud itself” (Marx 1990a: 266). However, the classical economists’ proposition that commodities’ values are determined by the amount of labor needed to produce them seems to make it impossible for profit to arise in the absence of cheating. Consider a worker who sells her labor on the market for $500 per 7 week, and assume that this sum is the full value of her labor; she is not being cheated. If commodities’ values are determined by the amount of labor needed to produce them, then $500 is also the amount of value her labor adds to the products she produces during the week. Now, if the capitalist sells the products at their value—so that the buyers are also not being cheated—he merely recoups the $500 he paid the worker. There is no profit. We therefore seem to have an insoluble dilemma: [Profit] cannot therefore arise from circulation, and it is equally impossible for it to arise apart from circulation. It must have its origin both in circulation and not in circulation.1 We therefore have a double result. The transformation of money into capital has to be developed on the basis of the immanent laws of the exchange of commodities, in such a way that the starting-point is the exchange of equivalents. The money-owner, who is as yet only a capitalist in larval form, must buy his commodities at their value, sell them at their value, and yet at the end of the process withdraw more value from circulation than he threw into it at the beginning. His emergence as a butterfly must, and yet must not, take place in the sphere of circulation. These are the conditions of the problem. Hic Rhodus, hic salta!2 Yet, Marx argued, there is indeed a solution. Contrary to what the classical economists assumed, workers’ labor is not a commodity bought in the “labor market.” Labor is the activity that workers engage in. What capitalists buy when they hire workers is instead their labor-power, or ability to work. The worker we introduced above was hired to be at work for a week, but how much actual work she did during the week is another matter. Thus, profit arises because the worker’s labor creates more value than the value of her labor-power. Although the $500 the worker was paid is the full value of her labor-power, the amount of new value created during a week’s worth of her labor will be greater, say $1,000. During the first half of the week, the worker creates the first $500 of new value, which replaces the amount of value she was paid. At this point, the capitalist has recouped the money he paid out in wages. However, the worker is compelled to work beyond this point—to perform surplus labor. She did, after all, contract to work for a whole week. Her labor during the remaining half-week creates an additional $500 of new value—surplus- value. It does not replace anything; the capitalist obtains it for free. This is the source of the profit and, according to Marx (1991a: 270), it is “the exclusive source of [the] profit.” Marx (1990a: 731) stressed that no cheating, and no violation of property rights, are involved in this process: If .
