There are even among thoroughgoing Darwinians some who draw the line at this (necessary) application of the development idea. Wallace says, at the conclusion of his defense of Darwinism: "The faculties of man could not possibly have been developed by means of the same laws which have determined the progressive development of the world in general, and also of man's physical organism"--the human body. He finds in the origin of Mind clear indications of "an unseen universe--a world of spirit, to which the world of matter is altogether subordinate." (_"Darwinism,"_ p. 320.) Yet the development of mind through merely physical forces is upheld to the present day by the majority of evolutionists. The doctrine is even found in public school texts. In Davis' _"Physical Geography,"_ a high-school text, we read page 341: "The greater intelligence of many land animals than of sea animals should also be regarded as a result of the development of land animals amid a greater variety of geographical conditions than is found in the seas. . . . The wonderful intelligence of man has been developed on the lands, because only on the lands is to be found the great variety of form, climate and products which can stimulate the development of high intelligence. It would have been as impossible for man to develop as an inhabitant of the dark and monotonous ocean floor as it has been for civilization to arise out of the frozen and lonesome lands of the Antarctic regions." Thus even the children of our generation are taught a doctrine which is not only unproven but so far falls short of explaining that which it was invented to explain that it cannot, by any correct definition, even be dignified with the name of a "working hypothesis." It is a theory of origins which fails to account for one thing precisely--Origins. CHAPTER THREE. The Testimony of the Rocks. We have seen that the principal argument for a development of the higher types of life from lower organisms is based upon a study of fossil remains (paleontology). The older the strata in the earth's surface, the simpler the animal forms imbedded therein; the more recent the strata, the more complex and highly developed the fossil remains. Popular scientific works, and books of refence [tr. note: sic] generally, quote it as an axiom: In the oldest rocks the simplest fossils are found, hence the higher animals are developed from the lower. Davis "Physical Geograhy" [tr. note: sic] says (page 17):
