ction that is
inseparably connected with the perpetuation of life. In short, we now
need a propagandism for extending the sex-education movement among the
masses of people.

For those who have already accepted sex-education, a survey of the
facts that created a demand for sex-instruction will give a clearer
outlook on the movement. The rapid increase of interest in
sex-education has been the result of widespread dissemination of
convincing facts concerning some common disharmonies that grow out of
the sexual problems of the human race. These facts which have led to
sex-education should be kept in mind by all who wish to understand or
to play a part in the instruction of young people.

It is quite unnecessary, and still more undesirable, to recite at
length in these lectures the social, medical, and psycho-pathological
facts concerning abnormal or perverted sexual processes. Fortunately,
the educational ends may be gained by a general review that points out
the bearings of the main lines of the sexual problems, the
misunderstandings and mistakes that education may help prevent and
correct.

[Sidenote: Parents should know reasons for sex-instruction.]

It is important that the general public, especially the parents, should
understand the reasons which have induced numerous physicians,
ministers, and educators to become active advocates of systematic
sex-instruction for young people. Although the movement has made
extensive progress in the ten years of propagandic work, is probably
true that the majority of even intelligent parents are not yet
convinced that their children need sex-instruction. This is due largely
to the fact that the parents have not yet been shown the reasons why it
is now, and always has been, unsafe to allow children to gain more or
less sexual information from unreliable and vulgar sources. In fact, it
is surprising to find many parents, especially mothers, who seem unable
to grasp the idea that their "protected" children can possibly get
impure information.

There are other parents who know that their children are almost sure to
get vulgar information regarding sexual matters, and that some young
people are likely to make sexual mistakes; but they calmly look upon
such things as part of the established order of the world.

Still another type of parents who should know the reasons for
sex-instruction are those who accept the traditional idea that their
daughters must be kept "protected" and "i
