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.

He regarded the struggle as one between Science and Religion. I believed
then, and am convinced now, that it was a struggle between Science and
Dogmatic Theology.

More and more I saw that it was the conflict between two epochs in the
evolution of human thought--the theological and the scientific.

So I kept on, and from time to time published New Chapters in the
Warfare of Science as magazine articles in The Popular Science Monthly.
This was done under many difficulties. For twenty years, as President of
Cornell University and Professor of History in that institution, I was
immersed in the work of its early development. Besides this, I could not
hold myself entirely aloof from public affairs, and was three times sent
by the Government of the United States to do public duty abroad: first
as a commissioner to Santo Domingo, in 1870; afterward as minister to
Germany, in 1879; finally, as minister to Russia, in 1892; and was
also called upon by the State of New York to do considerable labor in
connection with international exhibitions at Philadelphia and at Paris.
I was also obliged from time to time to throw off by travel the effects
of overwork.

The variety of residence and occupation arising from these causes may
perhaps explain some peculiarities in this book which might otherwise
puzzle my reader.

While these journeyings have enabled me to collect materials over a
very wide range--in the New World, from Quebec to Santo Domingo and from
Boston to Mexico, San Francisco, and Seattle, and in the Old World from
Trondhjem to Cairo and from St. Petersburg to Palermo--they have often
obliged me to write under circumstances not very favora
