I wish to begin what I have to say on this theme by frank acknowledgment that the idea of a future life often seems to me, as I suspect it has seemed to many reflective minds, all but unbelievable. It may be true, for all that, as many unbelievable things have turned out to be true. Indeed my present purpose is to argue as best I can that it is true. But I have to start with the recognition of a certain natural repugnance toward it, on the part of minds accustomed to look at things in the cold light of reason and common sense.
