Preface to the English Edition

The publication of an English version of "Das Kapital" needs no apology. On the contrary, an explanation might be expected why this English version has been delayed until now, seeing that for some years past the theories advocated in this book have been constantly referred to, attacked and defended, interpreted and misinterpreted, in the periodical press and the current literature of both England and America.

When, soon after the author's death in 1883, it became evident that an English edition of the work was really required, Mr. Samuel Moore, for many years a friend of Marx and of the present writer, and than whom, perhaps, no one is more conversant with the book itself, consented to undertake the translation which the literary executors of Marx were anxious to lay before the public. It was understood that I should compare the MS. with the original work, and suggest such alterations as I might deem advisable. When, by and by, it was found that Mr. Moore's professional occupations prevented him from finishing the translation as quickly as we all desired, we gladly accepted Dr. Aveling's offer to undertake a portion of the work; at the same time Mrs. Aveling, Marx's youngest daughter, offered to check the quotations and to restore the original text of the numerous passages taken from English authors and Blue books and translated by Marx into German. This has been done throughout, with but a few unavoidable exceptions.

The following portions of the book have been translated by Dr. Aveling: (I) Chapters X. (The Working- Day), and XI. (Rate and Mass of Surplus-Value); (2) Part VI. (Wages, comprising Chapters XIX. to XXII.); (3) from Chapter XXIV., Section 4 (Circumstances that &c.) to the end of the book, comprising the latter part of Chapter XXIV.,. Chapter XXV., and the whole of Part VIII. (Chapters XXVI. to XXXIII); (4) the two Author's prefaces. All the rest of the book has been done by Mr. Moore. While, thus, each of the translators is responsible for his share of the work only, I bear a joint responsibility for the whole.

The third German edition, which has been made the basis of our work throughout, was prepared by me, in 1883, with the assistance of notes left by the author, indicating the passages of the second edition to be replaced by designated passages, from the French text published in 1873.¹ The alterations thus effected in the text of the second edition generally coincided with changes prescribed by Marx in a set of MS. instructions for an English translation that was planned, about ten years ago, in America, but abandoned chiefly for want of a fit and proper translator. This MS. was placed at our disposal by our old friend Mr. F. A. Sorge of Hoboken N. J. It designates some further interpolations from the French edition; but, being so many years older than the final instructions for the third edition, I did not consider myself at liberty to make use of it otherwise than sparingly, and chiefly in cases where it helped us over difficulties. In the same way, the French text has been referred to in most of the difficult passages, as an indicator of what the author himself was prepared to sacrifice wherever something of the full import of the original had to be sacrificed in the rendering.

There is, however, one difficulty we could not spare the reader: the use of certain terms in a sense different from what they have, not only in common life, but in ordinary Political Economy. But this was unavoidable. Every new aspect of a science involves a revolution in the technical terms of that science. This is best shown by chemistry, where the whole of the terminology is radically changed about once in twenty years, and where you will hardly find a single organic compound that has not gone through a whole series of different names. Political Economy has generally been content to take, just as they were, the terms of commercial and industrial life, and to operate with them, entirely failing to see that by so doing, it confined itself within the narrow circle of ideas expressed by those terms. Thus, though perfectly aware that both profits and rent are but sub-divisions, fragments of that unpaid part of the product which the labourer has to supply to his employer (its first appropriator, though not its ultimate exclusive owner), yet even classical Political Economy never went beyond the received notions of profits and rents, never examined this unpaid part of the product (called by Marx surplus-product) in its integrity as a whole, and therefore never arrived at a clear comprehension, either of its origin and nature, or of the laws that regulate the subsequent distribution of its value. Similarly all industry, not agricultural or handicraft, is indiscriminately comprised in the term of manufacture, and thereby the distinction is obliterated between two great and essentially different periods of economic history: the period of manufacture proper, based on the division of manual labour, and the period of modern industry based on machinery. It is, however, self- evident that a theory which views modern capitalist production as a mere passing stage in the economic
