acy of eugenic methods. Mention may be made, for instance,
of _Population and Progress_ (1907), by Montague Crackanthorpe,
President of the Eugenics Education Society. See also, Havelock
Ellis, "Eugenics and St. Valentine," _Nineteenth Century and
After_, May, 1906. It may be mentioned that nearly thirty years
ago, Miss J.H. Clapperton, in her _Scientific Meliorism_ (1885,
Ch. XVII), pointed out that the voluntary restraint of
procreation by Neo-Malthusian methods, apart from merely
prudential motives, there clearly recognized, is "a new key to
the social position," and a necessary condition for "national
regeneration." Professor Karl Pearson's _Groundwork of Eugenics_,
(1909) is, perhaps, the best brief introduction to the subject.
Mention may also be made of Dr. Saleeby's _Parenthood and Race
Culture_ (1909), written in a popular and enthusiastic manner.

How widely the general principles of eugenics are now accepted as
the sound method of raising the level of the human race, was well
shown at a meeting of the Sociological Society, in 1905, when,
after Sir Francis Galton had read papers on the question, the
meeting heard the opinions of numerous sociologists, economists,
biologists, and well-known thinkers in various lands, who were
present, or who had sent communications. Some twenty-one
expressed more or less unqualified approval, and only three or
four had objections to offer, mostly on matters of detail
(_Sociological Papers_, published by the Sociological Society,
vol. ii, 1905).

If we ask by what channels this impulse towards the control of procreation
for the elevation of the race is expressing itself in practical life, we
shall scarcely fail to find that there are at least two such channels: (1)
the growing sense of sexual responsibility among women as well as men, and
(2) the conquest of procreative control which has been achieved in recent
years, by the general adoption of methods for the prevention of
conception.

It has already been necessary in a previous chapter to discuss the
far-reaching significance of woman's personal responsibility as an element
in the modification of the sexual life of modern communities. Here it need
only be pointed out that the autonomous authority of a woman over her own
person, in the sexual sphere, involves on her part a consent to the act of
procreation which must be deliberate
