"The claims of certain so-called scientific men as to 'science overthrowing religion' are as baseless as the fears of certain sincerely religious men on the same subject. The establishment of the doctrine of evolution in our time offers no more justification for upsetting religious beliefs than the discovery of the facts concerning the solar system a few centuries ago. Any faith sufficiently robust to stand the — surely very slight — strain of admitting that the world is not flat and does not move round the sun need have no apprehensions on the score of evolution, and the materialistic scientists who gleefully hail the discovery of the principle of evolution as establishing their dreary creed might with just as much propriety rest it upon the discovery of the principle of gravity." — Theodore Roosevelt
