The name of Eucken has become a familiar one in philosophical and religious circles. Until recent years the reading of his books was confined to those possessing a knowledge of German, but of late several have been translated into the English language, and now the students of philosophy and religion are agog with accounts of a new philosopher who is at once a great ethical teacher and an optimistic prophet. There is no doubt that Eucken has a great message, and those who cannot find time to make a thorough study of his works should not fail to know something of the man and his teachings. The aim of this volume is to give a brief and clear account of his philosophical ideas, and to inspire the reader to study for himself Eucken's great works.
