This volume endeavors to treat every aspect of the problem regarding a future life and especially emphasizes a large mass of facts that ought to have cumulative weight in deciding the issue. The facts consist of both spontaneous and experimental experiences, the latter designed not only to add to the force of the evidence, but to suggest more problems than the mere fact of survival. The work as a whole makes an effort to help readers who want a scientific view of the subject into a critical way of dealing with problems which are far larger than the case of mere survival.
