BERRY THE JOHNS HOPKINS UNIVERSITY NE of the outstanding, possibly the only difference between man and the other animals is his ability to profit by the experience and accumulated wisdom of the race, and yet, despite this characteristic, each generation seems to produce its quota of antivaccinationists, anti-evolutionists and believers in a flat earth. We may still entertain the hope that the race is becoming more rational when we recall that it has taken about three centuries to convince the Anglo-Saxon and a few other races among the countless millions of the globe that the earth is not flat, so that to-day only the leader of Zion City (Voliva) among leading cosmologists defends the pentateuchal view. I do not wish to be thought of as sneering at any one's beliefs, and I fully realize that there are a great many earnest Christian men and women who are perturbed at anything that they think, rightly or wrongly, will shake the foundations of their faith, who are puzzled by the present outspoken opposition to evolution, and who wish to know what is the truth. No truer article of faith was ever penned than the motto of the Johns Hopkins UniversityVeritas vos liberabit—and to you seekers after truth I would like to explain away certain misconceptions, before undertaking to show you that the record of earth history is the record of evolu tion, and not to be disputed by honest people. Evolution is not a theory of origins, nor an article of scientific faith, but an indisputable fact. We could not teach geology without teaching evolution. One of the difficulties to the layman is the confusion of evolution-the record of the past and present history of organisms-with the various theories that have been proposed to explain its factors or mode of operation. Let me emphasize that evolution, the record, is in an altogether different category from the theories such as Darwinism, Lamarckianism, or any other VOL. XV-7 |
