We have no right to shut our eyes to facts and close our ears to evidence merely because Moses forbade the Hebrews to allow witches to live, or because some of the phenomena carry with them suggestions that do not altogether harmonise with the conventional orthodox theories of future life.

The whole question that lies at bottom is whether this world is divine or diabolic.

Those who believe it divine are bound by that belief to regard every phenomenon as a window through which man may gain fresh glimpses of the wonder and the glory of the Infinite.

In this region, as in all others, faith and fear go ill together.
It is impossible for any impartial man to read the narratives of which the present book is composed without feeling that we have at least one hint or suggestion of quite incalculable possibilities in telepathy or thought transference.

If there be, as many of these stories seem to suggest, a latent capacity in the human mind to communicate with other minds, entirely regardless of the conditions of time and space, it is undeniable that this would be a fact of the very first magnitude.
