Dedication
TO MY WIFE
Note
“It is no proof of wisdom to refuse to examine certain phenomena because we think it certain that they are impossible, as if our knowledge of the universe were already completed.”
—Prof. Lodge.
“The most ardent Spiritist should welcome a searching inquiry into the potential faculties of spirits still in the flesh. Until we know more of these, those other phenomena to which he appeals must remain unintelligible because isolated, and are likely to be obstinately disbelieved because they are impossible to understand.”—F. W. H. Myers: “Proceedings of the Society for Psychical Research,” Part XVIII, April, 1891.
