Q.E.D. Or New Light on the Doctrine of Creation By GEORGE McCREADY PRICE _Professor of Chemistry and Physics, Lodi Academy, California Author of "Outlines of Modern Science and Modern Christianity," "The Fundamentals of Geology," "God's Two Books," "Back to the Bible," "A Text-Book of General Science," etc._ "... and set you square with Genesis again." --_Robert Browning_. 1917 _To WILLIAM CLEAVER WILKINSON Scholar, Critic, Poet and Christian Gentleman This book is dedicated by one who owes to his advice and kindly sympathy more than can be expressed_ Preface The great world disaster, ushered in with the dawn of that August morning in 1914, has already brought revolutionary changes in many departments of our thinking. But not the least of the surprises awaiting an amazed world, whenever attention can again be directed to such subjects, will be the realization that we have now definitely outgrown many notions in science and philosophy which in the old order of things were supposed to have been eternally settled. There are but two theories regarding the origin of our world and of the various forms of plants and animals upon it, Creation and Evolution,--the latter assuming many modifications. The essential idea of the Evolution theory is _uniformity_; that is, it seeks to show that life in all its various forms and manifestations probably originated by causes similar to or identical with forces and processes now prevailing. It teaches the absolute supremacy and the past continuity of natural law as now observed. It says that the changes now going on in our modern world have always been in action and that these present-day natural changes and processes are as much a part of the origin of things as anything that ever took place in the past. In short, Evolution as a philosophy of nature is an effort to smooth out all distinction between Creation and the ordinary processes of nature that are now under the régime of "natural law."
