allow nothing to
interfere with his right to eat such food as he chooses, and is not
going to give up a dish he likes because it happens to be peppered with
arsenic. It may be so, let us grant, among savages. The growth of
civilization lies in ever-extended self-control guided by foresight.

[156] I have summarized some of the evidence on these points, especially
that showing that sexual attraction tends to be towards like persons and
not, as was formerly supposed, towards the unlike, in _Studies in the
Psychology of Sex_, Vol. IV, "Sexual Selection in Man."

[157] In other words, the process of tumescence is gradual and complex.
See Havelock Ellis, _Studies in the Psychology of Sex_, Vol. III, "The
Analysis of the Sexual Impulse."

[158] 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."

[159] 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_).

Pathologique_, 1910, Vol. I, p. 25. Grasset proceeds to discuss the
principles which must guide the physician in such consultations.

[161] This has been clearly realized by the German Society of Eugenics or
"Racial Hygiene," as it is usually termed in Germany (Internationale
