This volume represents the Ingersoll Lecture of 1922. The author does not propose to discuss the details of the questionnaire sent out as an attempt to collect information as to the general attitude of educated persons towards the belief in immortality, or the answers given to it. Lake desires merely to set forth the reasons which lead so many reluctantly to decline a prospect dear to our forefathers & attractive to ourselves, and secondly to describe a new attitude towards life which seems to be taking its place.
