This book is a plea for religion, worship, prayer—for the inner life. Darwin, James, Bergson and others are discussed. The facts of science and of Biblical criticism are surveyed, and the conclusion that is reached is that there is a world of spirit, and that in this spiritual life Jesus is the best guide. The author’s style of writing is vigorous, eloquent and suggestive. “A book of unusually fine quality. The author has a great message for such a time as this. The book will help men to be efficient instruments of God in the world.”—_Christian Intelligencer._ “A book from the pen of this Quaker professor is always worth while, and this little volume is in the same worthy class. It combines scholarship and mystic interpretation, and furnishes at once food for thought and inspiration for devotion.”—_Western Christian Advocate._ Studies in Mystical Religion _Cloth, gilt top, 518 pages, $3.00_ PRESS NOTICES “The book is written with clearness and quiet dignity. It is animated throughout by breadth of fine and kindly sympathies, and by a sense of the character of religion as a light and a power that from within control all the social fulfilments of our nature.”—_Philosophical Review._ “Such a work as this is not only a contribution of great timeliness in these days when the thoughts of scholarly men are turning perhaps as not before for centuries toward religion, but will go far to give mysticism, of which perhaps Quakerism is the best American illustration, a standing even at the bar of science.”—_American Journal of Religious Psychology._ “It is a book of wide and conscientious research, solid and steady structure and noble aim. The style is clear and definite, free of any attempt to dazzle or confuse. Those who have come to feel that the seat of authority in religion lies in the first-hand experience of the soul will turn eagerly to it, opening up as it does so many channels of the spiritual life in the past.”—_North American Review._ “It is a careful study of subjective religion, from the New Testament down to modern times. A vast field is covered and covered completely. The writer has made excellent use of his materials and given a sympathetic study of religion on its subjective and personal side.”—_New York Times._ “It shows abundant evidence of conscientious research and a careful study of sources either not easily accessible or generally passed over by the student. Sufficient attention has been given to the analytical investigation of the subject.”—_The Churchman._
