to young men the estimates as to
prevalence of social diseases and, therefore, of promiscuity. Fear of
consequences will not control one who is led to believe that he is
doing what most men do. (See Parkinson in _Educational Review_, Jan.
1911, pp. 44-46.)

[3] Many writers have discounted the value of warnings involved in
sex-instruction concerning social disease (see especially Cabot's
papers referred to in Sec. 46, and Parkinson in _Educational Review_,
January, 1911).

[4] Louise Creighton, in her excellent little book on "The Social
Disease and How to Fight It" (Longmans), has well presented the
problems of social impurity from woman's point of view.

Dr. W.S. Hall, in "Life's Problems," has given in a few pages the
necessary protective knowledge.

[5] See "The Sexual Necessity," by Drs. Howell and Keyes.

[6] See also, Henderson's "Education with Reference to Sex."

[7] See chapter on "Motherhood and Marriage" in Foerster's "Marriage
and the Sex Problem."

[8] As an illustration of this fact, out of 558 Pittsburgh
professional prostitutes, 406 had never had children. Of the 152 who
were mothers, only 24 had two or more children.

[9] Many thinking men and women now agree with Ellen Key that
"marriage is immoral without mutual love," that "love is the sole
decisive point of view in questions concerning this relationship,"
that "it will come to pass that no finely sensitive woman will become
a mother except through mutual love," that "everything which is
exchanged between husband and wife in their life together can only be
the free gift of love, can never be demanded by one or the other as a
right." (Key--"The Morality of Woman.")

[10] Foerster, in his "Marriage and the Sex Problem," urges that
self-control over sexual passions is the working of the old idea of
asceticism, which he believes "should be regarded, not as a negation
of nature nor as an attempt to extirpate natural forces, but as
practice in the art of self-discipline. Its object should be to show
humanity what the human will is capable of performing, to serve as an
encouraging example of the conquest of the spirit over the animal
self." My personal view is that nothing is gained by confusing
self-control and the old asceticism.

[11] Misunderstood, it seems to me, because her philosophy demanding
that marriage begin with, exist with, and end with love means freedom
in love, and this has been misinterpreted as "free love" in the sense
of p
