all the essential points of this great controversy are included.
By grouping under these comprehensive heads the facts to be
considered, and dealing with each group separately, we shall
doubtless acquire clear views of their inter-connection and their
historical succession.

I have treated of these conflicts as nearly as I conveniently
could in their proper chronological order, and, for the sake of
completeness, have added chapters on--

An examination of what Latin Christianity has done for modern
civilization.

A corresponding examination of what Science has done.

The attitude of Roman Christianity in the impending conflict, as
defined by the Vatican Council.

The attention of many truth-seeking persons has been so
exclusively given to the details of sectarian dissensions, that
the long strife, to the history of which these pages are devoted,
is popularly but little known. Having tried to keep steadfastly
in view the determination to write this work in an impartial
spirit, to speak with respect of the contending parties, but
never to conceal the truth, I commit it to the considerate
judgment of the thoughtful reader.
