These additions certainly afford us a new epoch in the annals of the solar system, and of astronomy itself. It is somewhat remarkable, that Herschel, who in the course of his observations traced certain nebulae, the light from which must have been two millions of years in reaching the earth, should never have remarked these planets, which, so to speak, lay at his feet. It reminds one of Esop's astrologer, who, to the amusement of his ignorant countrymen, while he was wholly occupied in surveying the heavens, suddenly found himself plunged in a pit. These new planets also we are told are fragments of a larger planet: how came this larger planet never to have been discovered?
Till Herschel's time we were content with six planets and the sun, making up the cabalistical number seven. He added another.
But these four new ones entirely derange the scheme. The astronomers have not yet had opportunity to digest them into their places, and form new worlds of them. This is all unpleasant. They are, it seems, "fragments of a larger planet, which had by some unknown cause been broken to pieces." They therefore are probably not inhabited. How does this correspond with the goodness of God, which will suffer no mass of matter in his creation to remain unoccupied? Herschel talks at his ease of whole systems, suns with all their attendant planets, being consigned to destruction. But here we have a catastrophe happening before our eyes, and cannot avoid being shocked by it.
"God does nothing in vain." For which of his lofty purposes has this planet been broken to pieces, and its fragments left to deform the system of which we are inhabitants; at least to humble the pride of man, and laugh to scorn his presumption? Still they perform their revolutions, and obey the projectile and gravitating forces, which have induced us to people ten thousand times ten thousand worlds. It is time, that we should learn modesty, to revere in silence the great cause to which the universe is indebted for its magnificence, its beauty and harmony, and to acknowledge that we do not possess the key that should unlock the mysteries of creation.
One of the most important lessons that can be impressed on the human mind, is that of self-knowledge and a just apprehension of what it is that we are competent to achieve. We can do much. We are capable of much knowledge and much virtue. We have patience, perseverance and subtlety. We can put forth considerable energies, and nerve ourselves to resist great obstacles and much suffering. Our ingenuity is various and considerable. We can form machines, and erect mighty structures. The invention of man for the ease of human life, and for procuring it a multitude of pleasures and accommodations, is truly astonishing. We can dissect the human frame, and anatomise the mind. We can study the scene of our social existence, and make extraordinary improvements in the administration of justice, and in securing to ourselves that germ of all our noblest virtues, civil and political liberty. We can study the earth, its strata, its soil, its animals, and its productions, "from the cedar that is in Lebanon, to the hyssop that springeth out of the wall."
But man is not omnipotent. If he aspires to be worthy of honour, it is necessary that he should compute his powers, and what it is they are competent to achieve. The globe of earth, with "all that is therein," is our estate and our empire. Let us be content with that which we have. It were a pitiful thing to see so noble a creature struggling in a field, where it is impossible for him to distinguish himself, or to effect any thing real.
There is no situation in which any one can appear more little and ludicrous, than when he engages in vain essays, and seeks to accomplish that, which a moment's sober thought would teach him was utterly hopeless.
Even astronomy is to a certain degree our own. We can measure the course of the sun, and the orbits of the planets. We can calculate eclipses. We can number the stars, assign to them their places, and form them into what we call constellations.
But, when we pretend to measure millions of miles in the heavens, and to make ourselves acquainted with the inhabitants of ten thousand times ten thousand worlds and the accommodations which the creator has provided for their comfort and felicity, we probably engage in something more fruitless and idle, than the pigmy who should undertake to bend the bow of Ulysses, or strut and perform the office of a warrior clad in the armour of Achilles.
How beautiful is the "firmament; this majestical roof fretted with golden fire!" Let us beware how we mar the magnificent scene with our interpolations and commentaries! Simplicity is of the essence of the truly great. Let us look at the operations of that mighty power from which we ourselves derive our existence, with humility and reverential awe! It may well become us. Let us not "presume into the heaven of heavens," unbidden, unauthorised guests! Let us adopt the counsel of the apostle, and allow no man to "spoil us through vain philosophy." The business of human life is serious; the useful investigations in which we may engage are multiplied. It is excellent to see a rational being conscious of his genuine province, and not idly wasting powers adapted for the noblest uses in unmeasured essays and ill-concocted attempts.
