publication and of sundry attacks which it elicited, I was asked
to maintain my thesis before various university associations and
literary clubs; and I shall always remember with gratitude that
among those who stood by me and presented me on the lecture
platform with words of approval and cheer was my revered
instructor, the Rev. Dr. Theodore Dwight Woolsey, at that time
President of Yale College.

My lecture grew--first into a couple of magazine articles, and
then into a little book called The Warfare of Science, for
which, when republished in England, Prof. John Tyndall wrote a
preface.

Sundry translations of this little book were published, but the
most curious thing in its history is the fact that a very
friendly introduction to the Swedish translation was written by a
Lutheran bishop.

Meanwhile Prof. John W. Draper published his book on The
Conflict between Science and Religion, a work of great ability,
which, as I then thought, ended the matter, so far as my giving
it further attention was concerned.

But two things led me to keep on developing my own work in this
field: First, I had become deeply interested in it, and could not
refrain from directing my observation and study to it; secondly,
much as I admired Draper's treatment of the questions involved,
his point of view and mode of looking at history were different
from mine.
