"And are there not in our inner nature phenomena of weight and motion comparable to those of physical nature? Suspense, to choose an example vividly familiar to everybody, is painful only as a result of the law in virtue of which the weight of a body is multiplied by its velocity. The weight of the feeling produced by suspense increases by the constant addition of past pain to the pain of the moment. "And then, to what, unless it be to the electric fluid, are we to attribute the magic by which the Will enthrones itself so imperiously in the eye to demolish obstacles at the behest of genius, thunders in the voice, or filters, in spite of dissimulation, through the human frame? The current of that sovereign fluid, which, in obedience to the high pressure of thought or of feeling, flows in a torrent or is reduced to a mere thread, and collects to flash in lightnings, is the occult agent to which are due the evil or the beneficent efforts of Art and Passion--intonation of voice, whether harsh or suave, terrible, lascivious, horrifying or seductive by turns, thrilling the heart, the nerves, or the brain at our will; the marvels of the touch, the instrument of the mental transfusions of a myriad artists, whose creative fingers are able, after passionate study, to reproduce the forms of nature; or, again, the infinite gradations of the eye from dull inertia to the emission of the most terrifying gleams. "By this system God is bereft of none of His rights. Mind, as a form of matter, has brought me a new conviction of His greatness." After hearing him discourse thus, after receiving into my soul his look like a ray of light, it was difficult not to be dazzled by his conviction and carried away by his arguments. The Mind appeared to me as a purely physical power, surrounded by its innumerable progeny. It was a new conception of humanity under a new form. This brief sketch of the laws which, as Lambert maintained, constitute the formula of our intellect, must suffice to give a notion of the prodigious activity of his spirit feeding on itself. Louis had sought for proofs of his theories in the history of great men, whose lives, as set forth by their biographers, supply very curious particulars as to the operation of their understanding. His memory allowed him to recall such facts as might serve to support his statements; he had appended them to each chapter in the form of demonstrations, so as to give to many of his theories an almost mathematical certainty. The works of Cardan, a man gifted with singular powers of insight, supplied him with valuable materials. He had not forgotten that Apollonius of Tyana had, in Asia, announced the death of a tyrant with every detail of his execution, at the very hour when it was taking place in Rome; nor that Plotinus, when far away from Porphyrius, was aware of his friend's intention to kill himself, and flew to dissuade him; nor the incident in the last century, proved in the face of the most incredulous mockery ever known--an incident most surprising to men who were accustomed to regard doubt as a weapon against the fact
