In its earlier abridged form this address was given as a Phi Beta Kappa
oration at Brown University, and, as a lecture, at New York, Boston,
New Haven, Ann Arbor, and elsewhere. In that form, substantially, it
was published in THE POPULAR SCIENCE MONTHLY. I have now given it
careful revision, correcting some errors, and extending it largely
by presenting new facts and developing various points of interest in
the general discussion. Among the subjects added or rewrought are: in
Astronomy, the struggle of Galileo and the retreat of the Church after
its victory; in Chemistry and Physics, the compromise between Science
and Theology made by Thomas Aquinas, and the unfortunate route taken
by Science in consequence; in Anatomy and Medicine, the earlier growth
of ecclesiastical distrust of these sciences; in Scientific Education,
the dealings of various European universities with scientific studies;
in Political and Social Science, a more complete statement of the
opposition of the Church, on Scriptural grounds, to the taking of
interest for money; and, in the conclusion, a more careful summing up.
If I have seemed to encumber the text with notes, it has been in the
intention to leave no important assertion unsupported; and in the hope
that others--less engrossed with administrative care than myself--may
find in them indications for more extended studies in various parts of
the struggle which I have but sketched.
