Professor Bergson himself admits that his discussion of Dreams (T.
Fisher Unwin, 2s. 6d. net), now first translated by E. E. Slosson, stops on the very threshold of the mystery; but it is well worth reading.-At the same time we have received Henri Bergson (Macmillan and Co., 5s. net), a con- scientious account of his life and philosophy by two of his closest students and translators, Algot Ruhe and Nancy M. Paul.-The Philosophy of Change (same publishers, 6s. net) is a study of the fundamental principle of M. Bergson's philosophy, by H. Wildon Carr, which was originally delivered as a course of lectures in the University of London.-Those who wish to work up to K Bergson gradually may do so in the clear and comprehensive History of Philosophy (G. Bell and Sons, 10s. 6d. net) just published by Professor Frank Thilly, of Cornell University.
