This secrecy has not always been maintained. When the Catholic Church was
at the summit of its power and influence it fully realized the magnitude
of sexual problems and took an active and inquiring interest in all the
details of normal and abnormal sexuality. Even to the present time there
are certain phenomena of the sexual life which have scarcely been
accurately described except in ancient theological treatises. As the type
of such treatises I will mention the great tome of Sanchez, _De
Matrimonio_. Here you will find the whole sexual life of men and women
analyzed in its relationships to sin. Everything is set forth, as clearly
and as concisely as it can be--without morbid prudery on the one hand, or
morbid sentimentality on the other--in the coldest scientific language;
the right course of action is pointed out for all the cases that may
occur, and we are told what is lawful, what a venial sin, what a mortal
sin. Now I do not consider that sexual matters concern the theologian
alone, and I deny altogether that he is competent to deal with them. In
his hands, also, undoubtedly, they sometimes become prurient, as they can
scarcely fail to become on the non-natural and unwholesome basis of
asceticism, and as they with difficulty become in the open-air light of
science. But we are bound to recognize the thoroughness with which the
Catholic theologians dealt with these matters, and, from their own point
of view, indeed, the entire reasonableness; we are bound to recognize the
admirable spirit in which, successfully or not, they sought to approach
them. We need to-day the same spirit and temper applied from a different
standpoint. These things concern everyone; the study of these things
concerns the physiologist, the psychologist, the moralist. We want to get
into possession of the actual facts, and from the investigation of the
facts we want to ascertain what is normal and what is abnormal, from the
point of view of physiology and of psychology. We want to know what is
naturally lawful under the various sexual chances that may befall man, not
as the born child of sin, but as a naturally social animal. What is a
