out
that which they considered untrue, they have forced him to a new and
more searching study of the questions involved, thereby strengthening
his belief in the truthfulness of his conclusions._

_To the second edition of The Psychical Correlation of Religious Emotion
and Sexual Desire, the author has seen fit to add certain other essays.
In preparing these essays for publication, he has borrowed freely from
his published papers, therefore, he desires to thank the publishers of
the New York Medical Record, Century Magazine, Denver Medical Times,
Charlotte Monthly and American Naturalist for granting him permission to
use such of his published material (belonging to them) as he saw fit._

_The author asks the indulgence of the reader for certain repetitions in
the text. These have not been occasioned by any lack of data, but occur
simply because he believes that an argument is rendered stronger and
more convincing by the frequent use of the same data whenever and
wherever it is possible to use them. When this plan is followed, the
reader, so the author believes, becomes familiar with the author's line
of thought, and is, consequently, better able to comprehend and
appreciate his meaning._

_Finally, the author has been led to the publication of these essays by
a firm belief in the truthfulness of the propositions advanced therein.
He may not live to see these propositions accepted, yet he believes
that, in the future, perhaps, in worthier and more able hands, they will
be so weightily and forcibly elaborated and advanced that their verity
will be universally acknowledged._

_The author, after mature consideration, has thought it advisable to
confine the subject matter of the Third Edition of Religion and Lust
almost wholly to the psychical correlation of religious emotion and
sexual desire. He has eliminated certain of the psychical problems
embraced in the First and Second Editions and has added instead a
bibliography. The student, he thinks, will find these changes of value,
especially in the matter of reference. The author has also added certain
data to the thesis of the work, as well as foot-notes; which, he thinks,
will strengthen the deductions and conclusions therein enunciated. He
has carefully and conscientiously edited and verified all notes and
quotations to be found in the book and rests satisfied in the conviction
that, whatever may
