Up to the present day Science has ignored psychology and opposed the claims of psycho-therapeutics. Medical science other than that depending on surgery will soon find that the process of readjustment in the human organism rendered necessary by the rapidly changing conditions of modern civilization and the opening-up of new centres of activity in the mind-sphere of the world, will present a new series of pathological conditions to which the prescriptions of the Pharmacopoeia are altogether inadequate. The psychic origin of disease will have to be admitted and provided against. The x-factor in human pathology which defies the action of drugs and evades the scalpel, call it by what name we may, will increasingly assert itself, and medical men will have perforce to take it into their counsels, make friends with it and get to understand its vagaries. The plurality of worlds and the habitability of the other planets in the solar system, taught by Pythagoras in the sixth century B.C., has received a certain speculative recognition by astronomers, notably Camille Flammarion, Richard Proctor, Schiaparelli and Sir Robert Ball, in recent years. It was affirmed as fact by that remarkable man of science and inspiration, Baron Swedenborg. But in a contemporary issue of the journal of the Royal Astronomical Society of Canada, Prof. Aitken, of the Lick Observatory, states, as the result of his researches, that the Moon is a dead world, with the exception perhaps of low forms of vegetable life sustained by water vapour exuding from the Moon’s interior; Mercury gets seven times as much heat as the Earth and keeps the same face towards the Sun, offering the alternative of an eternal night or an equally unending tropical heat and daylight, from which it is not protected by any atmosphere. Venus, having many characteristics similar to the Earth, is admitted to be problematical, since it is not yet decided whether its day and year are equal or not. If they are, then it is uninhabitable. Mars has a rare atmosphere, and there is not enough water on the planet to fill an American lake. It has a low temperature, and there may be vegetable and animal life there, but no beings of intelligence. The “canals” may be natural or artificial canals or merely earthquake markings. Jupiter is a semi-sun, its development is in a state of chaos, and it is probably gaseous throughout with matter distributed as on the Sun, there being no defined surface or crust. Saturn resembles Jupiter, but probably is not so far advanced, and it is even less fitted for human habitation than Jupiter.
