[140] Dr. Havelock Ellis furnishes a number of proofs of this fact in his frequently quoted book. According thereto, woman, among wild and half-wild people, is not only equal to man in physical strength and size of body, but she is partly superior. On the other side, Ellis agrees with others that, in consequence of our progress in civilization, the difference in the capacity of the skull of the two sexes has steadily become more marked. [141] This is a discovery, first made by Karl Marx, and classically demonstrated by him in his works, especially in "Capital." The Communistic Manifesto, that appeared in 1848, and was composed by K. Marx and Frederick Engels, is grounded upon this fundamental principle, and must be considered, to this day, as the norm for all agitational work, and the most excellent of all. [142] "The Hall of science is the Temple of democracy," Buckle, "History of Civilization in England." [143] Ziegler, quoted above, denies that such is the meaning of Virchow's argument. His own quotation of Virchow's argument, however, confirms the interpretation. Virchow said: "Now, only picture to yourselves _how the theory of the descent of man presents itself in the head of a Socialist_! (Laughter.) Yes, gentlemen, that may seem funny to some; it is, however, a serious matter, and I hope that the theory of the descent of man _may not bring upon us all the horrors that similar theories have actually brought upon our neighboring country. At any rate, this theory, if consistently carried out, has a side of extraordinary gravity; and that Socialism has shown its sympathy therewith, will, it is to be hoped, not have escaped you. We must be perfectly clear upon that._" Now, then, we have simply done what Virchow feared: we have drawn the conclusions from the Darwinian theories, conclusions that Darwin himself and a large portion of his followers either did not draw at all, or drew falsely. And Virchow warned against the gravity of these theories, just because he foresaw that Socialism would _and was bound to draw the conclusions that are involved in them_. [144] Dubois-Reymond repeated this sentence in February, 1883, to the attacks directed upon him, on the occasion of the anniversary celebration of Frederick the Great.
