It may be here remarked that this incident seems difficult to explain on any other hypothesis than that of independent clairvoyance. To explain it on the principle of telepathy would involve the necessity of presupposing that some person or persons knew of the dangerous situation of the rock, and that they were in telepathic rapport with the percipient. Either supposition seems improbable, although not impossible. Be this as it may be, the fact remains that the subjective mind of man has some means of reaching out beyond the range of our faculties of objective perception, and of knowing when and where danger threatens the individual. That it is constantly on the alert for that purpose, is also certain. But its efforts are not directed exclusively to the protection of the body from harm. It is also on the alert for the protection of the material interests of the individual, and for the advancement of whatever aims and objects he has in life. These objects are, of course, subsidiary to the main one, being means to the end in view,--namely, the preservation of human life. One of the most eminent lawyers in the United States informs me confidentially that he is often guided, in critical emergencies, by a voice which gives him in a single, concise sentence the key to the situation. All the years of his adult life this voice has warned him of impending danger, and guided him to the attainment of the objects of his ambition. He did not, in early life, entertain any well-defined theory on the subject of the origin of the voice, but has always been guided by its monitions, and never to his disadvantage. Of late years, however, he has become convinced of its true source, and now regards his faculty as of the most transcendent interest and scientific importance, to say nothing of its value as a personal mentor.
