“In his extensive work on the mystical manifestations of human nature, the German naturalist and philosopher, Maximilian Perty, has devoted a whole chapter to the Modern Forms of Magic.
“The manifestations of magical life”, he says in his Preface, “partially repose on quite another order of things than the nature in which we are acquainted with time, space, and causality; these manifestations can be experimented with but little; they cannot be called out at our bidding, but may be observed and carefully followed whenever they occur in our presence; we can only group them by analogy under certain divisions, and deduce from them general principles and laws.”
Thus, for Professor Perty, who evidently belongs to the school of Schopenhauer, the possibility and naturalness of the phenomena which took place in the presence of Kavindasami, the fakir, and are described by Louis Jacolliot, the Orientalist, are fully demonstrated in the principle.”
