Dr. Alfred Russel Wallace: The subject is one on which I have no special knowledge, and the only suggestion I can make is, that perhaps it might be shown how the special mental peculiarities of women have arisen through selection of those who were in every way best fitted for the production and rearing of healthy children. Many, perhaps all of the characteristics mentioned, have almost certainly been thus evolved; and it is, in my opinion, one of the condemnations of our present social system, that it has led to the deterioration of a large proportion of the women both of the highest and the lowest social grades, in these most vital qualities.
