not useful for young men. They serve a good
purpose by informing mature men and women and awakening them to the
necessity of legislation, education, and other weapons with which we
may fight the great black plague of social vice. For the average young
man the books recommended in Sec. 8 will give sufficient information and
viewpoint.

[Sidenote: Liaisons.]

(6) Finally, the young man of adolescent years should be made to
understand his responsibility for immorality that is not prostitution,
that is, extra-marital relations with his girl friends and without

Sec. 34. _Need of More Refinement in Men_

While refinement is a part of general culture, it is beyond doubt an
important phase of the problems for the larger sex-education.
Elsewhere I have referred to the need of better understanding and
better adjustment between men and women, especially in marriage.

increasingly important one, for here in America there is growing up a
generation of boys who are far from chivalrous even to their mothers
and sisters; and at the same time, the industrial competition and daily
association of the two sexes is making young men realize that women are
simply human beings and not super beings.

With regard to language, I am thin
