as the years go by.
Because of this state of affairs millions of human beings die every
generation, and other millions suffer the tortures of the damned while
they live, when they should enjoy the delights of the elect, and would
do so if they only knew the actual facts in the case, and would act in
accordance with the knowledge that ought to be made theirs.

But there are not wanting signs of the times that there will slowly
come a change in these conditions. The fact is that the intelligent
world is beginning to emerge from a condition of conformity to the
say-so of some one supposed to speak with authority, and to come into
a realm of obedience only to a law that has a scientific basis of
actual knowledge for its foundation.

For untold ages the sex relations of the human family have been
directed and determined by the clergy and by _their_ teachings and
pronunciamentos regarding what was fit and right. There is no need of
saying hard things about such a fact; nevertheless, it is true that,
for the most part, all the dicta of these men have originated amongst
those who knew nothing of the _scientific_ conditions regarding the
subject on which they issue their mandates. So did the blind lead the
blind, and the ditches of the past years are filled to overflowing
with the dead bodies and souls of men and women, who, for this cause,
have fallen therein.

This must not always be! It is neither wise nor right that the
essential matters of human life should always remain a stumbling block
and a rock of offense for the children of men. We are coming to see
that sex is no more unclean and to be denied a scientific knowledge
of, than any other part of the human body--the eye, the ear or
whatsoever. Furthermore, the rank and file are beginning to clamor
for a knowledge of these matters for themselves. This is shown by
the frequency of articles that deal with sex in many of the best
newspapers and magazines in the civilized world, and by similar
discussions in the literature, the works and scientific books that now
go into the hands of the common people. It also shows in the attempts
that are occasionally being made to introduce the subject of sexual
hygiene into our public schools and other educational institutions.
"The world do move!"

It is for these reasons--because it is right to transfer to you and to
those who come after, the sex knowledge that has been acquired by the
author, by reading scientific and professional
