This volume is based upon the sixteenth series of lectures delivered at Yale University on the Foundation established by the late Dwight H. Terry of Plymouth, Connecticut, through his gift of an endowment fund for the delivery and subsequent publication of "Lectures on Religion in the Light of Science and Philosophy." The deed of gift declares that "the object of this Foundation is not the promotion of scientific investigation and discovery, but rather the assimilation and interpretation of that which has been or shall be hereafter discovered, and its application to human welfare, especially by the building of the truths of science and philosophy into the structure of a broadened and purified religion.
