it not comical, this appeal (of Marx) to Hegelian confusion and mistiness, that quantity changes into quality." Confused mixture, who changes his ground, who is a comical fellow Herr Duehring?
All these pretty little statements are not only not "axiomatic utterances" according to label, but are simply taken from foreign sources, that is, from Hegel's "Logic." Of a truth there is not revealed in the whole chapter the shadow of any "inner connection," except so far as it is borrowed from Hegel, and the whole talk about stability and change finally runs out into mere garrulity on the subject of time and space.
From existence Hegel comes to substance, to the dialectic. Here he treats of reflex-movements, antagonisms and contradictions, positive and negative for example, and thence proceeds to causality, or the conditions of cause and effect and closes with necessity. Herr Duehring does not vary this method. What Hegel calls the "doctrines of existence" Herr Duehring has translated into "logical properties of existence." These exist, above all else in the antagonism of forces, in antithesis, Herr Duehring denies the antithesis in toto, but we shall return to this matter later. Then he proceeds to causality and thence to necessity. If Herr Duehring says of himself, "I do not philosophise from a cage," he must mean that he philosophises in a cage, the cage of the Hegelian arrangement of categories.
