It is a mortifying circumstance, which greatly perplexes many a painstaking philosopher, that nature often refuses to second his most profound and elaborate efforts; so that after having invented one of the most ingenious and natural theories imaginable, she will have the perverseness to act directly in the teeth of his system, and flatly contradict his most favorite positions. This is a manifest and unmerited grievance, since it throws the censure of the vulgar and unlearned entirely upon the philosopher; whereas the fault is not to be ascribed to his theory, which is unquestionably correct, but the waywardness of Dame Nature, who, with the proverbial fickleness of her sex, is continually indulging in coquetries and caprices, and seems really to take pleasure in violating all philosophic rules, and jilting the most learned and indefatigable of her adorers. Thus it happened with respect to the foregoing satisfactory explanation of the motion of our planet; it appears that the centrifugal force has long since ceased to operate, while its antagonist remains in undiminished potency; the world, therefore, according to the theory as it originally stood, ought in strict propriety to tumble into the sun; philosophers were convinced that it would do so, and awaited in anxious impatience the fulfilment of their prognostics. But the untoward planet pertinaciously continued her course, notwithstanding that she had reason, philosophy, and a whole university of learned professors opposed to her conduct. The philosophers took this in very ill part, and it is thought they would never have pardoned the slight and affront which they conceived put upon them by the world, had not a good-natured professor kindly officiated as a mediator between the parties, and effected a reconciliation. Finding the world would not accommodate itself to the theory, he wisely determined to accommodate the theory to the world; he therefore informed his brother philosophers, that the circular motion of the earth round the sun was no sooner engendered by the conflicting impulses, above described, than it became a regular revolution, independent of the causes which gave it origin. His learned brethren readily joined in the opinion, being heartily glad of any explanation that would decently extricate them from their embarrassment; and ever since that memorable era the world has been left to take her own course, and to revolve around the sun in such orbit as she thinks proper. =Chapter II.= COSMOGONY, OR CREATION OF THE WORLD; WITH A MULTITUDE OF EXCELLENT THEORIES, BY WHICH THE CREATION OF A WORLD IS SHOWN TO BE NO SUCH DIFFICULT MATTER AS COMMON FOLK WOULD IMAGINE.
