As Roswell Johnson remarks ("The Evolution of Man and its Control," Popular Science Monthly, January, 1910): "While it is undeniable that love when once established defies rational considerations, yet we must remark that sexual selection proceeds usually through two stages, the first being one of mere mutual attraction and interest. It is in this stage that the will and reason are operative, and here alone that any considerable elevation of standard may be effective."

Galton looked upon eugenics as fitted to become a factor in religion (Essays in Eugenics, p. 68). It may, however, be questioned whether this consummation is either probable or desirable. The same religious claim has been made for socialism. But, as Dr. Eden Paul remarks in a recent pamphlet on Socialism and Eugenics, "Whereas both Socialism and Eugenics are concerned solely with the application of the knowledge gained by experience to the amelioration of the human lot, it seems preferable to dispense with religious terminology, and to regard the two doctrines as complementary parts of the great modern movement known by the name of Humanism." Personally, I do not consider that either Socialism or Eugenics can be regarded as coming within the legitimate sphere of religion, which I have elsewhere attempted to define (Conclusion to The New Spirit).
