Staudenmaier, who has experimented on himself magically to a great extent and has set down his experiences recently in the interesting book, “Die Magie als experimentelle Naturwissenschaft,” thinks he has observed that through the exercise that he carries on, and which produces an intense introversion, psychophysical energies are set free that make him capable of greater efficiency. Specifically, an actual drawing upon the nerve centers unused in the conscious function of the normal man of to-day would be available for intellectual work, etc. So, as it were, a treasure can be gained (by practices having a significant introversion character), a treasure which permits an increased thinking and feeling activity. If Staudenmaier, even in the critical examination of his anomalous functions, can be influenced by them, it would be a great mistake to put them aside simply as “pathological.” Ennemoser says of the danger of introversion (l. c., p. 175): “Now where in men of impure heart, through the destructive natural powers and evil spiritual relations, the deepest transcendental powers are aroused, dark powers may very easily seize the roots of feeling and reveal moral abysses, which the man fixed in the limits of time hardly suspects and from which human nature recoils. Such an illicit ecstasy and evil inspiration is at least recognized in the religious teachings of the Jews and Christians, and the seers of God describe it as an agreement with hell (Isaiah XXVIII, 15).” Whence comes the danger? It comes from the powerful attraction for us of that world which is opened to us through introversion. We descend there to whet our arms for fresh battles, but we lay them down; for we feel ourselves embraced by soft caressing arms that invite us to linger, to dream enchanting dreams. This fact coincides in large part with the previously mentioned tendency toward comfort, which is unwilling to forego childhood and a mother’s careful hands. Introversion is an excellent road to lazy phantasying in the regressive direction.
