peace is preserved and forever established by
the very fact that one function of the mind directly requires the other,
one possession directly guarantees the other. This is the standpoint of the
author, and from it he has endeavored to treat all the questions which are
to be taken into consideration. Should he, by his exposition of this
standpoint, succeed in helping even a few readers in reaching the
conviction of the actual harmony between the scientific, religious, and
ethical acquisitions of mankind, or in confirming them anew in such
conviction, he would find himself amply rewarded for this first extended
venture before the public.

AUTHOR'S PREFACE TO AMERICAN EDITION.

Six years have elapsed since I wrote the book which is now going forth in
English dress. The great leader of the theories in question has passed
away; the waves of thought he set in motion are assuming smoother shape;
and I can only add to what I have already written, that not only have I had
no occasion to retract any of the statements or views laid down in the
book, but I perceive the religious as well as the scientific world growing
more and more into accord with the views I have maintained, and which were
at first so vehemently opposed.

I owe so much to the literary men of the English tongue on both sides of
the Atlantic, that I shall be glad if, through the devoted labors of the
translator, I am enabled to pay them a tribute of gratitude by aiding them
in clearing the way for thought in these much disputed fields, or in
reconciling in their minds the conflict between faith and science.

INTRODUCTION TO AMERICAN EDITION,

BY THE DUKE OF ARGYLL.

* * * * *

It is well known that Mr. Darwin's theory on the Origin of Species has been
accepted in Germany more widely, with more absolute faith, and with more
vehement enthusiasm, than in the country of its birth. In Germany, more
conspicuously than elsewhere, it has itself become the subject of
developments as strange and as aberrant as any which it assumes in the
history of Organic Life. The most extravagant conclusions have been drawn
from it--invading every branch of human thought, in Science, in Philosophy,
and in Religion. These conclusions have been preached, too, with a
dogmatism as angry and as intolerant as any of the old theologies
