This book would never have been written
had I not been honored with an appointment as Gifford
Lecturer on Natural Religion at the University of
Edinburgh. In casting about me for subjects of
the two courses of ten lectures each for which I thus
became responsible, it seemed to me that the first
course might well be a descriptive one on “Man’s
Religious Appetites,” and the second a metaphysical
one on “Their Satisfaction through Philosophy.”
But the unexpected growth of the psychological
matter as I came to write it out has resulted in the
second subject being postponed entirely, and the description
of man’s religious constitution now fills the
twenty lectures. In Lecture xx I have suggested
rather than stated my own philosophic conclusions,
and the reader who desires immediately to know them
should turn to pages 501-509, and to the “Postscript”
of the book. I hope to be able at some later
day to express them in more explicit form.
In my belief that a large acquaintance
with particulars often makes us wiser than the possession
of abstract formulas, however deep, I have loaded
the lectures with concrete examples, and I have chosen
these among the extremer expressions of the religious
temperament. To some readers I may consequently
seem, before they get beyond the middle of the book,
to offer a caricature of the subject. Such convulsions
of piety, they will say, are not sane. If, however,
they will have the patience to read to the end, I
believe that this unfavorable impression will disappear;
for I there combine the religious impulses with other
principles of common sense which serve as correctives
of exaggeration, and allow the individual reader to
draw as moderate conclusions as he will.
My thanks for help in writing these
lectures are due to Edwin D. Starbuck, of Stanford
University, who made over to me his large collection
of manuscript material; to Henry W. Rankin, of East
Northfield, a friend unseen but proved, to whom I owe
precious information; to Theodore Flournoy, of Geneva,
to Canning Schiller of Oxford, and to my colleague
Benjamin Rand, for documents; to my colleague Dickinson
S. Miller, and to my friends, Thomas Wren Ward, of
New York, and Wincenty Lutoslawski, late of Cracow,
for important suggestions and advice. Finally,
to conversations with the lamented Thomas Davidson
and to the use of his books, at Glenmore, above Keene
Valley, I owe more obligations than I can well express.
