women's rights movement depends on precisely the same cause.
It is clear that the principle of the existence of innumerable individual proportions of the male and female principles is a basis of the study of character which must be applied in any rational scheme of pedagogy.
The science of character must be associated with some form of psychology that takes into account some theory of the real existence of mental phenomena in the same fashion that anatomy is related to physiology. And so it is necessary, quite apart from theoretical reasons, to attempt to pursue a psychology of individual differences. This attempt will be readily enough followed by those who believe in the parallelism between mind and matter, for they will see in psychology no more than the physiology of the central nervous system, and will readily admit that the science of character must be a sister of morphology. As a matter of fact there is great hope that in future characterology and morphology will each greatly help the other. The principle of sexually intermediate forms, and still more the parallelism between characterology and morphology in the widest application, make us look forward to the time when physiognomy will take its honourable place amongst the sciences, a place which so many have attempted to gain for it but as yet unsuccessfully.
The problem of physiognomy is the problem of the relation between the static mental forces and the static bodily forces, just as the problem of physiological psychology deals with the dynamic aspect of the same relations. It is a great error in method, and in fact, to treat the study of physiognomy, because of its difficulty, as impracticable. And yet this is the attitude of contemporary scientific circles, unconsciously perhaps rather than consciously, but occasionally becoming obvious as for instance in the case of the attempt of von Möbius to pursue the work of Gall with regard to the physiognomy of those with a natural aptitude for mathematics. If it be possible, and many have shown that it is possible, to judge correctly
