[KN]If elimination of the unintellectual (not necessarily of the unintelligent) may be excluded, and if the unintellectual increase by natural generation more rapidly than the intellectual, the general level of intellectuality must, on Professor Weismann's principles, be steadily falling.
[KO]It may also, in part, be due to "organic combination."
