The aim of the present volume is to indicate the measure of harmony traceable between recent advances in science, and the fundamental character istics of religious thought, and the extent to which harmony is possible. This attempt has been made in the hope of contributing towards a better understanding of the relative positions of scientists and theologians, thereby aiding the formation of public opinion on questions appearing to involve serious antagonism.

The plan followed is to bring under review the great fields of scientific inquiry, advancing from unorganized existence to Man; to present the most recent results of research in these separate fields, without extending to minute details; as far as possible, to allow scientific observers to state results in their own words; and then to examine carefully the reasonings deduced from ascertained facts, and the bearing of facts and inferences on religious thought.

The general result is that marked modifications of thought concerning the structure and order of the universe have arisen on account of scientific discoveries, to be accepted by theologians, as by all thinkers; that the bearing of these modifications on religious conceptions has been greatly mistaken by many scientific observers; and that it must be held clear by scientists and theologians alike, that while scientific methods are reliable within their own spheres, science can bear no testimony, and can offer no criticism, as to the supernatural, inasmuch as science is only an explanation of ascertained facts by recognition of natural law.
