world is, so to speak, a formula of pure logic, to signify the self-contained condition of matter as the point of departure of all enumerable stages of material progress."
We have obviously not yet got away from the original self-contained condition of matter. Here it is explained as consisting of mechanical force and matter, and this as a formula of pure logic, etc. As soon then as the unity of matter and mechanical force is at an end evolution proceeds.
The formula of pure logic is nothing but a lame attempt to make the Hegelian categories "an Sich and fuer Sich" of use in a philosophy of realism. In "an Sich" according to Hegel the original unity of a thing consists; in "fuer Sich" begins the differentiation and movement of the concealed elements, the active antithesis. We shall therefore depict the original condition as one in which there is a unity of matter and mechanical force and the transition to movement as the separating and antithesis of these two elements. But we have not thereby established the proof of the real existence of the fantastic original condition but only this much that it exists according to the Hegelian category "an Sich" and just as fantastically disappears according to the Hegelian category "fuer Sich."
Matter, says Duehring, implies all that is real, therefore there is no mechanical force outside of matter. Mechanical force is furthermore a condition of matter. In the original condition where no change occurred matter and its mechanical force were a unity. Afterwards when the change commenced there was a differentiation from matter. Thus we are obliged to be satisfied with these mystical phrases and with the assurance that the self contained original state was neither static nor
