Dear Sir, Replying to your note of the 14th of last month, may I thank you for your kindness in sending me your work on Marx; I had already read it with great interest in the issue of the Archiv which Dr. H. Braun was good enough to send me, and was pleased for once to find such understanding of Capital at a German University. Naturally I can t altogether agree with the wording in which you render Marx s exposition. Especially the definitions of the concept of value which you give on pages 576 and 577 seem to me to be rather all-embracing: I would first limit them historically by explicitly restricting them to the economic phase in which alone value has up to now been known, and could only have been known, namely, the forms of society in which commodity exchange, or commodity production, exists; in primitive communism value was unknown. And secondly it seems to me that the concept could also be defined in a narrower sense. But this would lead too far, in the main you are quite right. Then, however, on page 586, you appeal directly to me, and the jovial manner with which you hold a pistol to my head made me laugh. But you need not worry, I shall not assure you of the contrary. The logical sequence by which Marx deduces the general and equal rate of profit from the different values of s / C = s / (c + v) produced in various capitalist enterprises is completely foreign to the mind of the individual capitalist. Inasmuch as it has a historical parallel, that is to say, as far as it exists in reality outside our heads, it manifests itself for instance in the fact that certain parts of the surplus value produced by capitalist A over and above the rate of profit, or above his share of the total surplus value, are transferred to the pocket of capitalist B whose output of surplus value remains as a rule below the customary dividend. But this process takes place objectively, in the things, unconsciously, and we can only now estimate how much work was required in order to achieve a proper understanding of these matters. If the conscious co-operation of the individual capitalists had been necessary to establish the average rate of profit, if the individual capitalist had known that he produces surplus value and how much of it, and that frequently he has to hand over part of his surplus value, then the relationship between surplus value and profit would have been fairly obvious from the outset and would presumably have already been described by Adam Smith, if not Petty. According to Marx s views all history up to now, in the case of big events, has come about unconsciously, that is, the events and their further consequences have not been intended; the ordinary actors in history have either wanted to achieve something different, or else what they achieved has led to quite different unforeseeable consequences. Applied to the economic sphere: the individual capitalists, each on his own, chase after the biggest profit. Bourgeois economy discovers that this race in which every one chases after the bigger profit results in the general and equal rate of profit, the approximately equal ratio of profit for each one. Neither the capitalists nor the bourgeois economists, however, realise that the goal of this race is the uniform proportional distribution of the total surplus value calculated on the total capital. But how has the equalisation been brought about in reality? This is a very interesting point, about which Marx himself does not say much. But his way of viewing things is not a doctrine but a method. It does not provide ready-made dogmas, but criteria for further research and the method for this research. Here therefore a certain amount of work has to be carried out, since Marx did not elaborate it himself in his first draft. First of all we have here the statements on pages 153-156, III, I,  which are also important for your rendering of the concept of value and which prove that the concept has or had more reality than you ascribe to it. When commodity exchange began, when products gradually turned into commodities, they were exchanged approximately according to their value. It was the amount of labour expended on two objects which provided the only standard for their quantitative comparison. Thus value had a direct and real existence at that time. We know that this direct realisation of value in exchange ceased and that now it no longer happens. And I believe that it won t be particularly difficult for you to trace the intermediate links, at least in general outline, that lead from directly real value to the value of the capitalist mode of production, which is so thoroughly hidden that our economists can calmly deny its existence. A genuinely historical exposition of these processes, which does indeed require thorough research but in return promises amply rewarding results, would be a very valuable supplement to Capital. Finally, I must also thank you for the high opinion which you have formed of me if you consider that I could have made something better of volume III. I cannot share your opinion, and believe I have done my duty by presenting Marx in Marx s words, even at the risk of requiring the reader to do a bit more thinking for himself. ...
