It is only fair to any one who may take up this book, to say that it is made up of lectures given, for the most part, before the Society for Ethical Culture of Chicago. It is due to my colleagues in the Ethical Movement to say that they are not responsible for the views here expressed, that the book nowise claims to represent the Movement, but simply reflects my own attitude of mind upon the various topics treated. Even in discussing "The Basis of the Ethical Movement," I but give my own interpretation of it. The bond of union between the lecturers, as between the members, of Ethical Societies is not a speculative but a moral one. I must add, however, that my own intellectual indebtedness to Professor Adler is so great that it would be difficult to measure it. Many of the thoughts in this volume - probably the best ones - are really his thoughts; he has given me, or at least quickened in my mind, ideas that will never go from me, that are a part of my better self.
