=AN INTRODUCTION TO METAPHYSICS=. By HENRI BERGSON. Translated by T. E. Hulme. Fcap. 8vo, Cloth, price, 2s. 6d. net. The "Introduction to Metaphysics," although the shortest, is one of the most important of Bergson's writings. It not only provides the best introduction to his thought, but is also a book which even those familiar with the rest of his work will find necessary to read, for in it he develops at greater length and in greater detail than elsewhere, the exact significance of what he intends by the word "intuition." Every expositor of Bergson has hitherto found it necessary to quote "An Introduction to Metaphysics" at considerable length, yet the book has never before been available in English. =AN INTRODUCTION TO BERGSON=. By T. E. HULME. 7s. 6d. Besides giving a general exposition of the better known parts of Bergson's philosophy, the author has discussed at some length Bergson's "Theory of Art," which may prove to many people the most interesting part of his whole philosophy, although it has so far been written about very little. At the same time this book is no running commentary on a great number of separate ideas; the author has endeavoured by subordinating everything to one dominating conception, to leave in the reader's mind a clearly outlined picture of Bergson's system. During the last few years the author has been able to discuss many points of difficulty with M. Bergson himself. SOCIAL AND POLITICAL SERIES =FROM THEATRE TO MUSIC-HALL=. By W. R. TITTERTON. Crown 8vo, cloth. 3s. 6d. net. This book is neither a history of the drama nor a critical study of well-known playwrights. It is an attempt to account for the weakening of the dramatic sense in modern England, and to explain the enormous importance of the music-hall, and the desperate necessity of maintaining it as a means of popular expression. The theories put forward are bold, and are likely to excite great agreement and great opposition. =THE DOCTOR AND HIS WORK.= With a Hint of his Destiny and Ideals. By CHARLES J. WHITBY, M.D. Cantab., Author of "Triumphant Vulgarity," "Makers of Man," "A Study of Human Initiative," etc. Crown 8vo, cloth. Price 3s. 6d. net. In this book the author has reviewed the existing position of the doctor and indicated the signs of a new sociological era in which he will be called upon to accept new and important functions. The profession has in the past consisted of a mere mob of unorganised units; that of the future will be a disciplined army of experts co-operating for the good of the State. "The Doctor and His Work" may be described as a summary of the modern medical point of view. It appeals not less to the lay than to the professional reader. =IRISH HOME RULE.= The Last Phase. By S. G. HOBSON. Crown 8vo. 3s. 6d. net.
