But Herr Dühring cannot permit himself such a ****** treatment of the subject. He thinks not only in the name of humanity -- in itself no small achievement -- but in the name of the conscious and reasoning beings on all celestial bodies.
Indeed, it would be "a degradation of the basic forms of consciousness and knowledge to attempt to rule out or even to put under suspicion their sovereign validity and their unconditional claim to truth, by applying the epithet 'human' to them" {2}.
Hence, in order that no suspicion may arise that on some celestial body or other twice two makes five {30-31}, Herr Dühring dare not designate thought as being human, and so he has to sever it from the only real foundation on which we find it, namely, man and nature; and with that he tumbles hopelessly into an ideology [33] which reveals him as the epigone of the "epigone" Hegel {197}. By the way, we shall often meet Herr Dühring again on other celestial bodies.
It goes without saying that no materialist doctrine can be founded on such an ideological basis. Later on we shall see that Herr Dühring is forced more than once to endow nature surreptitiously with conscious activity, with what in plain language is called God.
However, our philosopher of reality had also other motives for shifting the basis of all reality from the real world to the world of thought.
The science of this general world schematism, of these formal principles of being, is precisely the foundation of Herr Dühring's philosophy.
If we deduce world schematism not from our minds, but only through our minds from the real world, if we deduce principles of being from what is, we need no philosophy for this purpose, but positive knowledge of the world and of what happens in it; and what this yields is also not philosophy, but positive science. In that case, however, Herr Dühring's whole volume would be nothing but love's labour lost.
Further: if no philosophy as such is any longer required, then also there is no more need of any system, not even of any natural system of philosophy. The perception that all the processes of nature are systematically connected drives science on to prove this systematic connection throughout, both in general and in particular. But an adequate, exhaustive scientific exposition of this interconnection, the formation of an exact mental image of the world system in which we live, is impossible for us, and will always remain impossible. If at any time in the development of mankind such a final, conclusive system of the interconnections within the world -- physical as well as mental and historical -- were brought about, this would mean that human knowledge had reached its limit, and, from the moment when society had been brought into accord with that system, further historical development would be cut short -- which would be an absurd idea, sheer nonsense. Mankind therefore finds itself faced with a contradiction: on the one hand, it has to gain an exhaustive knowledge of the world system in all its interrelations;and on the other hand, because of the nature both of men and of the world system, this task can never be completely fulfilled. But this contradiction lies not only in the nature of the two factors -- the world, and man --it is also the main lever of all intellectual advance, and finds its solution continuously, day by day, in the endless progressive development of humanity, just as for example mathematical problems find their solution in an infinite series or continued fractions. Each mental image of the world system is and remains in actual fact limited, objectively by the historical conditions and subjectively by the physical and mental constitution of its originator.
But Herr Dühring explains in advance that his mode of reasoning is such that it excludes any tendency to a subjectively limited conception of the world. We saw above that he was omnipresent -- on all possible celestial bodies. We now see that he is also omniscient. He has solved the ultimate problems of science and thus nailed boards across the future of all science.
As with the basic forms of being, so also with the whole of pure mathematics: Herr Dühring thinks that he can produce it a priori that is, without ****** use of the experience offered us by the external world, can construct it in his head.
In pure mathematics the mind deals "with its own free creations and imaginations" {D. Ph. 43}; the concepts of number and figure are "the adequate object of that pure science which it can create of itself" {42}, and hence it has a "validity which is independent of particular experience and of the real content of the world" {43}.
That pure mathematics has a validity which is independent of the particular experience of each individual is, for that matter, correct, and this is true of all established facts in every science, and indeed of all facts whatsoever. The magnetic poles, the fact that water is composed of hydrogen and oxygen, the fact that Hegel is dead and Herr Dühring alive, hold good independently of my own experience or that of any other individual, and even independently of Herr Dühring's experience, when he begins to sleep the sleep of the just. But it is not at all true that in pure mathematics the mind deals only with its own creations and imaginations.
