The studious years spent in the reading room of the British Museum complete the anglicization of Marx. "Capital" is essentially an English work, the fact of its having been written in German, by a German writer, being merely incidental. No more distinctively English treatise on political economy was ever written, not even "The Wealth of Nations." Even the method and style of the book are, contrary to general opinion, much more distinctly English than German. I do not forget his Hegelian dialectic with its un-English subtleties, but against that must be placed the directness, vigor, and pointedness of style, and the cogent reasoning, with its wealth of concrete illustrations, which are as characteristically English. Marx belongs to the school of Petty, Smith, and Ricardo, and their work is the background of his. "Capital" was the child of English industrial conditions and English thought, born by chance upon German soil. Toward the middle of the nineteenth century, English economic thought was entirely dominated by the ideas and methods of Ricardo, who has been described by Senior, not without justice, as "the most incorrect writer who ever attained philosophical eminence."[152] So far as such a sweeping criticism can be justified by looseness in the use of terms, it is justified by Ricardo's failing in this respect. That he should have attained the eminence he did, dominating English economic thought for so many years, in spite of the confusion which his loose and uncertain use of words occasioned, is not less a tribute to Ricardo's genius than evidence of the poverty of political economy in England at that time. In view of the constant and tiresome reiteration of the charge that Marx pillaged his labor-value theory from Thompson, Hodgskin, Bray, or some other more or less obscure writer of the Ricardian school, it is well to remember that there is nothing in the works of any of these writers connected with the theory of value which is not to be found in the earlier work of Ricardo himself. In like manner, the theory can be traced back from Ricardo to the master he honored, Adam Smith. Furthermore, almost a century before the appearance of "The Wealth of Nations," Sir William Petty had anticipated the so-called Ricardian labor-value theory of Smith and his followers.
