1912. The chapters in this book were originally delivered as intercollegiate lectures at Westfield College, University of London, during the Michaelmas term. They arose out of the deep respect I feel for the work and personality of Professor Eucken, and from a profound sense of the importance of his teaching for philosophy, for religion, and for everyday life. Partial Contents: Eucken's Philosophical Publications; Eucken's Views on the Relation of Philosophy to History, Particularly to the History of Philosophy, Illustrated by His Own Handling of the Philosophy of Augustine-Eucken's Method; Eucken's Criticism of Naturalism; Eucken's Discussion of the Negative Movement; The Negative Movement Essential to a Religious Philosophy; The Great Alternative: Nature or Spirit, Individuality or Personality; Eucken's View of Revelation; Eucken's Theory of Knowledge; Unity and Multiplicity; and The Limitations of the Foregoing Treatment of Eucken's Philosophy.
