at therefore they do not exist. How many of us have seen the
microbe that kills? There are at least as many persons who testify they
have seen apparitions as there are men of science who have examined the
microbe. You and I, who have seen neither, must perforce take the
testimony of others. The evidence for the microbe may be conclusive, the
evidence as to apparitions may be worthless; but in both cases it is a
case of testimony, not of personal experience.

The first thing to be done, therefore, is to collect testimony, and by
way of generally widening the mind and shaking down the walls of
prejudice which lead so many to refuse to admit the clearest possible
evidence as to facts which have not occurred within their personal
experience, I preface the report of my "Census of Hallucinations" or
personal experiences of the so-called supernatural by a preliminary
chapter on the perplexing subject of "Personality." This is the question
that lies at the root of all the controversy as to ghosts. Before
disputing about whether or not there are ghosts outside of us, let us
face the preliminary question, whether we have not each of us a
veritable ghost within our own skin?

Thrilling as are some of the stories of the apparitions of the living
and the dead, they are less sensational than the suggestion made by
hypnotists and psychical researchers of England and France, that each of
us has a ghost inside him. They say that we are all haunted by a
Spiritual Presence, of whose existence we are only fitfully and
sometimes never conscious, but which nevertheless inhabits the innermost
recesses of our personality. The theory of these researchers is that
besides the body and the mind, meaning by the mind the Conscious
Personality, there is also within our material frame the soul or
Unconscious Personality, the nature of which is shrouded in unfathomable
mystery. The latest word of advanced science has thus landed us back to
the apostolic assertion that man is composed of body, soul and spirit;
and there are some who see in the scientific doctrine of the Unconscious
Personality a welcome confirmation from an unexpected quarter of the
existence of the soul.

The fairy tales of science are innumerable, and, like the fairy tales of
old romance, they are not lacking in the grim, the tragic, and even the
horrible. Of recent years nothing has so fascinated the imagination even
of the least imaginative of men as the theory of disease which
