IN this volume is presented the balance sheet of the Darwinian theory up to date, in all fields of human thought and endeavor, by the greatest and most brilliant authorities of England, France, Germany, and Scandinavia. Every writer stands internationally at the head of his branch. Thomson gives an historical survey of the antecedents of Darwinism, Bateson writes on heredity; Weismann sums up the results of the selection theory; Haeckel discusses Darwin as an anthropologist; the influence of evolution as philosophy is described by Professor Hoffding of the University of Upsala, one of the most eminent philosophical scholars of the world. Professor J. B. Bury, of Cambridge, tells of the development of history under the spur of the evolutionary idea. Religion is treated from the same point of view by P. H. Waggett, and sociology by C. Bougle, professor at the University of Toulouse and at the Sorbonne. And American scholarship is represented in the introduction by Professor Henry Fairfield Osborn, president of the American Museum of Natural History, one of our greatest scientists, and of world-wide reputation.

The book is an authentic statement of what has been accomplished in science and in thought since the enunciation of the Darwinian theory. It is a trustworthy, invaluable guide to everyone desiring to obtain a truthful picture of the present world of ideas.
