people, especially for
those of post-adolescent years. I know of teachers and physicians who
advise young people not much over twenty years of age to read such
psychopathological works as those of Krafft-Ebing, Ellis, and Freud,
and various works dealing with commercialized vice. Here is a grave
danger. The less that people without professional use for knowledge of
sexual pathology know concerning it, the better it will be for their
peace of mind and possibly for their morals. Therefore, I urge that he
who enthusiastically studies the abnormalities of sex life without
reference to scientific research or professional demands, is not likely
to be the kind of teacher who will present abnormal life only so far as
is necessary to an understanding of the perfectly normal.

[Sidenote: Pessimistic teachers.]

The fourth kind of people who ought not to instruct the young in
personal problems of sex-hygiene are the men and women whose own
unhappy romances or married life, or whose knowledge of vice
conditions, have made them pessimistic concerning sex-problems. There
are in our schools and colleges to-day some such men and many such
women, and there will be danger for young people when the growing
freedom of expression allows these sexual pessimists to impress their
own hopeless philosophy of sex upon students. The educational world
does not need such teachers, but rather those who can follow the late
Dr. Morrow in seeing a bright side of life that almost dispels the
darkness of sexual errors.

[Sidenote: Teachers not respected by pupils.]

The fifth kind of persons who ought not to teach the personal side of
sex-hygiene are those who cannot command the most serious respect of
their pupils. This applies especially to many men teachers whose
flippant attitude and even questionable living are not likely to help
their pupils, especially boys, towards a satisfactory interpretation of
sex problems. Of course, such teachers ought not be in schools at all,
but the fact is that for various reasons they sometimes get there and
stay there; and so they must be weighed by the school official who
selects the teachers to be intrusted with special problems of
sex-education.

[Sidenote: No instruction without satisfactory teachers.]

Summarizing, I have in this lecture aimed to warn the school
administrator, and others who must select teachers of classes, against
the kinds of teachers who ought not be chosen for presenting the
