Students of history find a continuous chain of reference to the mysterious influence of one human mind over that of others. In the earliest records, traditions and legends may be found giving reference to the general belief that it was possible for an individual to exert some weird uncanny power over the minds of other persons, which would influence the latter for good or evil. And more than this, the student will find an accompanying belief that certain individuals are possessed of some mental power which bends even things and circumstances to its might. Way back in the dim past of man's history on this planet, this belief existed, and it has steadily persisted in spite of the strenuous opposition of material science, even unto the present day. The years have not affected the belief, and in these dawning days of the Twentieth Century it has taken on a new strength and vitality, for its adherents have boldly stepped to the front, and confronting the doubting materialistic thinkers, have claimed the name of "Science" for this truth and have insisted that it be taken, once and for all, from the category of superstition, credulity and ignorant phantasm.
