At the present day there is the usual, perhaps more than the usual, passion to know whether, if a man die, he shall live again, and it takes the form of an intenser interest in the nature of the life after death than in the scientific question of the fact. This problem is discussed at some length in this work. It is not easy to satisfy inqui'rers on this point. Most of them sup pose that, if we can communicate with the discarnate, they can easily tell us all about the transcendental world. But this is an illusion and the sooner that we learn that there is a very large problem before us in that matter the better for our intellectual sanity. It is comparatively easy to prove survival, when you have once eliminated fraud and subconscious fabrica tions. But it is a very different matter to determine just what we shall believe or how we shall conceive the nature of the existence beyond the grave. It will be a matter of long investigation and all that I can hope to do in this work is to suggest the considera tions that must be taken into account when discussing the problem.
