Subjects which a few years ago were regarded as the exclusive property of cultured thinkers, are now common themes of thought and conversation. Psychology has been popularized. Materialistic doctrines are at a discount even in this age of physical science. It is difficult to explain the somewhat sudden appearance of intense interest in questions which have to do with the life of the spirit; but, whatever the theory of its genesis, there is no doubt of its presence. This, therefore, is a favorable time for a somewhat extended study of the stages through which we pass in our spiritual growth. I shall endeavor to use the inductive method in this inquiry, and trust that I am not presumptuous in giving to these essays the title, THE ASCENT OF THE SOUL.
