Apparent diameter of the sun being to Neptune but one-fortieth of the sun's apparent diameter to us,
and it is so dim and hazy when seen through the best telescope that it looks like an astronomical romance to call it one of our planets. Neptune's heat and light are reduced to 1/900 part of the heat and light received by the earth. His motion and that of his satellites have always looked suspicious. They do not agree—in appearance, at least—with those of the other planets. His system is retrograde, etc. But even the latter abnormal fact resulted only in the creation of new hypotheses by our Astronomers, who forthwith suggested a probable overturn of Neptune, his collision with another body, etc. Was Adams' and Leverrier's discovery so welcomed because Neptune was as necessary as was Ether to throw a new glory upon astronomical prevision, upon the certitude of modern scientific data, and principally upon the power of mathematical analysis? It would so appear. A new planet that widens our planetary domain by more than four hundred million leagues is worthy of annexation. Yet, as in the case of terrestrial annexation, scientific authority may be proved “right” only because it has “might.” Neptune's motion happens to be dimly perceived: Eureka! it is a planet! A mere motion, however, proves very little. It is now an ascertained fact in Astronomy that there are no absolutely fixed stars in Nature,[408] even though such stars should [pg 218] continue to exist in astronomical parlance, while they have passed from the scientific imagination. Occultism, however, has a strange theory of its own with regard to Neptune.
Occultism says that if several hypotheses resting on mere assumption—which have been accepted only because they have been taught by eminent men of learning—are taken away from the Science of Modern Astronomy, to which they serve as props, then even the presumably universal law of gravitation will be found to be contrary to the most ordinary truths of mechanics. And really one can hardly blame Christians—foremost of all the Roman Catholics—however scientific some of these may themselves be, for refusing to quarrel with their Church for the sake of scientific beliefs. Nor can we even blame them for accepting in the secresy of their hearts—as some of them do—the theological “Virtues” and “Archons” of Darkness, instead of all the blind forces offered them by Science.
Never can there be intervention of any sort in the marshalling and the regular precession of the celestial bodies! The law of gravitation is the law of laws; who ever witnessed a stone rising in the air against gravitation? The permanence of the universal law is shown in the behaviour of the sidereal worlds and globes eternally faithful to their primitive orbits; never wandering beyond their respective paths. Nor is there any intervention needed, as it could only be disastrous. Whether the first sidereal incipient rotation took place owing to an intercosmic chance, or to the spontaneous development of latent primordial forces; or again, whether that impulse was given once for all by God or Gods—it does not make the slightest difference. At this stage of cosmic evolution no intervention, superior or inferior, is admissible. Were any to take place, the universal clock-work would stop, and Kosmos would fall into pieces.
Such are stray sentences, pearls of wisdom, fallen from time to time from scientific lips, and now chosen at random to illustrate a query. We lift our diminished heads and look heavenward. Such seems to be the fact: worlds, suns, and stars, the shining myriads of the heavenly hosts, remind the Poet of an infinite, shoreless ocean, whereon move swiftly numberless squadrons of ships, millions upon millions of cruisers, large and small, crossing each other, whirling and gyrating in [pg 219] every direction; and Science teaches us, that though they be without rudder or compass or any beacon to guide them, they are nevertheless secure from collision—almost secure, at any rate, save in chance accidents—as the whole celestial machine is built upon and guided by an immutable, albeit blind, law, and by constant and accelerating force or forces. “Built upon” by whom? “By self-evolution,” is the answer. Moreover, as dynamics teach that
A body in motion tends to continue in the same state of relative rest or motion unless acted upon by some external force,
this force has to be regarded as self-generated—even if not eternal, since this would amount to the recognition of perpetual motion—and so well self-calculated and self-adjusted as to last from the beginning to the end of Kosmos. But “self-generation” has still to generate from something, generation ex-nihilo being as contrary to reason as it is to Science. Thus we are placed once more between the horns of a dilemma: are we to believe in perpetual motion or in self-generation ex-nihilo? And if in neither, who or what is that something, which first produced that force or those forces?
There are such things in mechanics as superior levers, which give the impulse and act upon secondary or inferior levers. The former, however, need an impulse and occasional renovation, otherwise they would themselves very soon stop and fall back into their original status. What is the external force which puts and retains them in motion? Another dilemma!
As to the law of cosmical non-intervention, it could be justified only in one case, namely, if the celestial mechanism were perfect; but it is not. The so-called unalterable motions of celestial bodies alter and change incessantly; they are very often disturbed, and the wheels of even the sidereal locomotive itself occasionally jump off their invisible rails, as may be easily proved. Otherwise why should Laplace speak of the probable occurrence at some future time of an out-and-out reform in the arrangement of the planets;[409] or Lagrange maintain the gradual narrowing of the orbits; or our modern Astronomers, again, declare that the fuel in the sun is slowly disappearing? If the laws and forces which govern the behaviour of the celestial bodies are immutable, such modifications and wearing-out of substance or fuel, of force and fluids, would be impossible; yet they are not denied. Therefore [pg 220] one has to suppose that such modifications will have to rely upon the laws of forces, which will have to self-regenerate themselves once more on such occasions, thus producing an astral antinomy, and a kind of physical palinomy, since, as Laplace says, one would then see fluids disobeying themselves and reäcting in a way contrary to all their attributes and properties.
Newton felt very uncomfortable about the moon. Her behaviour in progressively narrowing the circumference of her orbit around the earth made him nervous, lest it should end one day in our satellite falling upon the earth. The world, he confessed, needed repairing, and that very often.[410] In this he was corroborated by Herschel.[411] He speaks of real and quite considerable deviations, besides those which are only apparent, but gets some consolation from his conviction that somebody or something will probably see to things.
