INTRODUCTION: The present work is devoted chiefly to the discussion of three topics which, although in a measure independent one of the other, are, nevertheless, so closely allied that they may be viewed as parts of one and the same subject. The first of these topics embraces a brief sketch of the evolutionary theory from its earliest beginnings to the present time; the second takes up the pros and the cons of the theory as it now stands; while the third deals with the reciprocal and little understood relations between Evolution and Christian faith. This early works is a fascinating and informative look at the subject. Many of the earliest books, particularly those dating back to the 1900's and before, are now extremely scarce and increasingly expensive. We are republishing these classic works in affordable, high quality, modern editions, using the original text and artwork.
