an impassable gulf between them; to keep silence was no longer possible. Marx demonstrates in this reply the irreparable rupture which had taken place.
The summary of Marx's judgment of Proudhon is expressed in the article reproduced as an appendix to this work, which first appeared in the Sozialdemokrat of Berlin, Nos. 16, 17 and 18. It was the only article Marx ever wrote for that journal. The efforts of Herr von Schweitzer to drag the paper into governmental and feudal waters constrained us to publicly withdraw from it after a few weeks.

This is not the place to deal at length with the relations existing between Marx and Rodbertus; I may soon have the opportunity to do it. Suffice it here to say that when Rodbertus accuses Marx of having "pillaged" him, and of having in his "Capital" profited much by his work, "Zur Erkenntniss," &c., without making any acknowledgment, he allows himself to be guilty of a calumny which is only to be explained by the natural ill-humor of a misunderstood genius, and his remarkable ignorance of everything occurring outside of Prussia, and notably of Socialist and economic literature.
