(Duehring having made an attack upon Marx's "Capital" because of its reliance upon the dialectic, and having indulged in the epithets to which he is too prone with respect to this work, Engels takes up its defence in that respect as follows): It is not our business to concern ourselves at this point with the correctness or incorrectness of the investigations of Marx as regards economics, but only with the application which he makes of the dialectic method. So much is certain, that it is only now that the readers of "Capital" will by the aid of Herr Duehring understand what they have read properly, and among them Herr Duehring himself, who in the year 1867 was still in a position, as far as possible to a man of his calibre, to review the book rationally. He did not then, it may be noted, first translate the arguments of Marx into Duehringese, as now seems indispensable to him. Even if he at that time made the blunder of identifying the Marxian dialectic with that of Hegel he had not altogether lost the ability to distinguish methods from the results attained by them and to comprehend that an abuse of the former is no contradiction of the latter. Herr Duehring's most astonishing observation is that from the Marxian standpoint, "in the last analysis everything is identical," that therefore in the eyes of Marx, for example, capitalists and wage workers, feudal, capitalistic and social methods of production are "all one." In order to show the possibility of such sheer stupidity it only remains to point out that the mere word "dialectic" makes Herr Duehring mentally irresponsible and makes what he says and does so inaccurate and confused as to be in the last analysis "all one." * * * * * (Herr Duehring remarks, "How comical for example is the declaration based upon Hegel's confused notions that quantity becomes lost in quality and that money advanced [i.e. for productive purposes. Ed.] becomes capital when it reaches a certain limit merely through quantitative increase." To which Engels replies thus):
