The author of The Ego and Spiritual Truth (C. W.

Daniel. 7s. 6d.), announced as Mr. I. C. Isbyam, is presumably a mathematical physicist who has been impelled by the meta- physical perplexities so obviously confronting the scientist of to-day to pursue the study of philosophy in quest of a more satisfying outlook. The present book is a development of the ideas expressed in a former work, entitled The Ego and Physical Force, and takes the form of a discourse upon entities other than physical force. The introductory essay by Mr. Louis Zangwill is not particularly germane to the subject.
