It is perhaps rather to the great artists of our race than to any philosopher at all that these invisible ones reveal themselves, but in their gradual disclosure to the consciousness of the human race, they are certainly assisted by the most insane and unbalanced plunges into mystery, of this and the other abnormal individual. The paradox may indeed be hazarded that the madder and more abnormal are the individual's attempts to dig himself into the very nerves and fibres of reality, the clearer and more definite as far as consciousness of the race is concerned, does the revelation of these invisible ones grow. The abnormal individual whose complex vision is distorted almost out of human recognition by the predominance of some one attribute, is yet, in his madness and morbidity, a wonderful engine of research for the clairvoyance of humanity. The vision of the immortals, as a background to all further discussion, is rendered richer and more rhythmical every day, or rather the hidden rhythm of their being is revealed more clearly every day, by the eccentricities and maladies, nay! by the insanities and desperations, of individual victims of life. Thus it comes about that, while the supreme artists, whose approximation, to the vision of the invisible ones is closest, remain our unique masters, the lower crowd of moderately sane and moderately well-balanced persons are of less value to humanity than those abnormal and wayward ones whose psychic distortions are the world's perverted instruments of research. A philosopher of this unbalanced kind is indeed a sort of living sacrifice or victim of self-vivisection, out of whose demonic discoveries--bizarre and fantastic though they may seem to the lower sanity of the mob--the true rhythmic vision of the immortals is made clearer and more articulate. The kind of balance or sanity which such average persons, as are commonly called "men of the world," possess is in reality further removed from true vision than all the madness of these debauches of specialized research. For the consummation of the complex vision is a meeting place of desperate and violent extremes; extremes, not watered down nor modified nor even "reconciled," certainly not cancelled by one another, but held forcibly and deliberately together by an arbitrary act of the apex-thought of the human soul. As I glance at these basic activities of the complex vision one by one, I would beg the reader to sink as far as he can into the recesses of his own identity; so that he may discover whether what he finds there agrees in substance--call it by what name he pleases and explain it how he pleases--with each particular energy I name, as I indicate such energies in my own way.
