Professor W. McDougall, who made a real contribution to the

cause of peace by his advocacy of an International Air Force for the League of Nations—whether we agree in detail with his scheme or not—now takes the whole of human life for his field in Character and the Conduct of Life (Methuen. 10s. 6d.). Sophistry, as he says in his preface, is out of favour in the modern world, yet sophists are needed, now if ever. The wide range of this book and its compendious form will be rather against it, because most people, while ready to give unlimited time to their hobbies and amusements, consider that the art of living should be allowed to take care of itself, and swallow philosophical abstractions as they do a nasty medicine. None the less, we should be well adviSed to read Professor McDougall's chapters on " Character and Will " and on " Children and Parents," for they contain much high thinking and plain speaking. Another work on psychology, published by the same house, is a translation of Di, Hans Dreisch's Mind and Body (5s.). We only mention this book (" psychological parallelism " and " the manifoldness of the mind" are obviously not subjects to dismiss in a sentence) because Dr. Dreisch is of the vanguard of those who have led us out of the jungle of a materialistic psychology into some- thing saner.
