KEELY AND HIS DISCOVERIES AERIAL NAVIGATION BY Mrs. BLOOMFIELD MOORE The universe is ONE. There is no supernatural: all is related, cause and sequence. Nothing exists but substance and its modes of motion. Spinoza. LONDON KEGAN PAUL, TRENCH, TRÜBNER & CO., Ltd. PATERNOSTER HOUSE, CHARING CROSS ROAD 1893 John Stuart Mill, in order to protect science, carried empiricism to its extreme sceptical consequences, and thereby cut the ground from under the feet of all science.--Professor Otto Pfleiderer, D.D. The word of our God shall stand for ever.--Isa. xl. 8. Imagination is wholly taken captive by the stupendous revelation of the God-force which modern conceptions of the Cosmos furnish. Through the whole universe beats the one life-force, that is God, controlling every molecule in the petal of a daisy, in the meteoric ring of Saturn, in the remotest nebula that outskirts space, as though that molecule were the universe. In each molecule and atom God lives and moves and has His being, thereby sustaining theirs.... Prophet after prophet cries, and psalmist after psalmist sings, that so indeed he has found it; that therein is the divine sonship of man, therein the assurance of eternal life.--Rev. R. A. Armstrong. The living man with his interior consciousness of self and individuality is on two planes of nature at once, as a ship is in two media at once, half in the water and half in the air. To manage your ship successfully you must take cognizance of the laws governing each of those media. To deal successfully with your human being you must understand his physiology no doubt, but you must equally understand his psychology, and something of the collateral phenomena of nature in those regions or planes to which the phenomena of the psychic man belong.--A. P. Sinnett.
