mes, and as to the part which sex-instruction may play in the attempt
at finding a solution. Such work is now being done splendidly by the
societies named in Sec. 51. The magnitude of the problem of reaching the
public is such that there is abundant work for numerous branches of
such societies or for local groups willing to take a part in the needed
work. As suggested elsewhere, the success of the movement for
sex-instruction of children of school ages will depend largely upon the
attitude and cooperation of parents; and hence it is important that
parents should be led to understand the reasons or arguments for
sex-instruction. In other words, they should know the problems that
indicate the importance of enlightening the rising generation
concerning the great facts of sex and life.

[Sidenote: Books for parents.]

Among the numerous publications that seem to me adapted for convincing
parents that their children need instruction, I commonly mention the
following: Lowry's "False Modesty" and "Teaching Sex Hygiene," Howard's
"Start your Child Right," Wile's "Sex Education," Galloway's "Biology
of Sex," March's "Towards Racial Health," Lyttleton's "Training of the
Young in Laws of Sex," and pamphlets by Dr. Prince Morrow. See also
pages 241-243.

[Sidenote: Knowledge needed concerning eight sex problems.]

There are eight important sex problems of our times that offer reasons
or arguments for sex-instruction, because ignorance plays a large part
in each problem. I shall state them briefly here and discuss each in
succeeding lectures: (1) Many people, especially in youth, need
hygienic knowledge concerning sexual processes as they affect personal
health. (2) There is an alarming amount of the dangerous social
diseases which are distributed chiefly by the sexual promiscuity or
immorality of many men. (3) The uncontrolled sexual passions of men
have led to enormous development of organized and commercialized
prostitution. (4) There are living to-day tens of thousands of
unmarried mothers and illegitimate children, the result of the common
sexual irresponsibility of men and the ignorance of women. (5) There is
need of more general following of a definite moral standard regarding
sexual relationships. (6) There is a prevailing unwholesome attitude of
mind concerning all sexual processes. (7) There is very general
misunderstanding of sexual life as related to healthy and happy
marriage. (8) There is need of eugenic responsibi
