[11]. “If the petty motions of us mortals afford arguments for the being of a God, much more may those greater motions we see in the world, and the phænomena attending them: I mean, the motions of the planets and heavenly bodies. For these must be put into motion either by one common mighty Mover, acting upon them immediately, or by causes and laws of His appointment; or by their respective movers, who, for reasons to which you can by this time be no stranger,” (referring his reader to preceding arguments), “must depend upon some Superior, that furnished them with the power of doing this. And granting it to be done either of these ways, we can be at no great distance from a demonstration of the existence of a Deity.”—Wollaston’s Rel. of Nat. delineated, sect. v. head 14th.
[12]. A disciple of Anaximenes, and preceptor to Socrates. He died 428 years B. C. in the seventy-second year of his age.
[13]. Thales, of Miletus in Ionia, was one of the seven sages of Greece: he was born about six hundred and forty years before the Christian era. After travelling into other countries, he returned to his own, and there devoted himself exclusively to the study of nature. Being the first of the Greeks who made any discoveries in Astronomy, he is said to have astonished his countrymen, by predicting a solar eclipse; and he instructed them, by communicating the knowledge of geometry and astronomy, which he had acquired while in Egypt. He died in the ninety-sixth year of his age,—544 years B. C.
[14]. Marcus Tullius Cicero—the same that has been already mentioned. He was, himself, not only one of the most learned and eloquent men, but one of the greatest philosophers, of antiquity. This illustrious Roman (whose death occurred forty-three years before the Christian era) firmly believed in the being of a God. He was likewise a decided advocate for the doctrine of the soul’s immortality; concerning which, some fine reasoning will be found in his book on Old Age;—a doctrine, however, by no means confined to Cicero alone, but one maintained by many of the most eminent among the heathen philosophers, in the early ages. Plato appears to have been the first who supported that opinion upon sound and permanent arguments, deduced from truth and established principles.
[15]. Cicero himself says, “If any one doubt, whether there be a God, I cannot comprehend why the same person may not as well doubt, whether there be a sun or not.” [De Naturâ Deorum, 2. 2.]
It is observed by Dr. Turnbull, in his annotations on Heineccius’s System of Universal Law, that Polybius as well as Cicero, and indeed almost all the ancient philosophers, have acknowledged, that a public sense of Religion is necessary to the well-being and support of civil society: and such a sentiment of Religion is inseparable from a reasonable conception of the being and attributes of the Deity. “Society,” says Dr. Turnbull very truly, “can hardly subsist without it: or, at least, it is the most powerful mean for restraining from vice; and for promoting and upholding those virtues by which society subsists, and without which every thing that is great and comely in society must soon perish and go to ruin.”—“With regard to private persons,” continues this learned writer, “he who does not often employ his mind in reviewing the perfections of the Deity, and in consoling and strengthening his mind by the comfortable and mind-exalting reflexions, to which meditation upon the universal providence of an all-perfect mind, naturally, and as it were, necessarily lead, deprives himself of the greatest joy, the noblest exercise and entertainment, the human mind is capable of; and whatever obligations there may to virtue, he cannot be so firm, steady, and unshaken in his adherence to it, as he, who, being persuaded of the truth just mentioned, is daily drawing virtuous strength and comfort from it.” [See the Annotator’s remark on ch. v. b. i. of Heineccius.]
[16]. The Greeks derived their knowledge of astronomy from the Egyptians and Chaldeans. According to Plutarch, the sciences began to unfold themselves about the time of Hesiod, the Greek poet, who flourished upwards of nine centuries before the Christian era; but their progress was very slow, until the time of Thales, which was about three centuries later. And although this celebrated philosopher of antiquity rendered himself famous by foretelling an eclipse of the sun, he only predicted the year in which it was to happen. Even this, it is remarked by Mr. Vince (in his invaluable work, entitled, A Complete System of Astronomy,) he was probably enabled to do by the Chaldean Saros, a period of 223 lunations; after which, the eclipses return again nearly in the same order. Philolaus, a disciple of Pythagoras, lived about four hundred and fifty years before Christ, and is said to have taught the true solar system,—placing the sun in the centre, with the earth and all the planets revolving about it; a system which, it is believed, Pythogaras himself had conceived, and was inclined to adopt.
However, Hipparchus, who lived between one hundred and twenty-five and one hundred and sixty years before the Christian era, and whom Mr. Vince styles “the Father of Astronomy,” was the first person that cultivated every part of that science. His discoveries, together with those of Ptolemy, are preserved in the Μεγαλη Σύνταξις, or Great Construction,—Ptolemy’s celebrated work on Astronomy, named by the Arabs the Almagest, and now usually so called.
[17]. This great philosopher of antiquity, so justly entitled to celebrity for his mathematical works, flourished three hundred years before the Christian era. Care should be taken not to confound him with Euclid of Megara, who lived a century earlier. The latter, as the Abbé Barthelemi observes, being too much familiarized with the writings of Parmenides and the Elean school, had recourse to abstractions; “a method,” says the Abbé, “often dangerous, oftener unintelligible.” Just after, he adds: “The subtleties of metaphysics calling to their aid the quirks of logic, words presently took place of things, and students acquired nothing in the schools but a spirit of acrimony and contradiction.” Travels of the younger Anacharsis, vol. iii. chap. 37.
[18]. That the sun is at rest, and that the planets revolve round him, is an opinion that appears to have been received of old, by Philolaus, Aristarchus of Samos, and the whole sect of the Pythagoreans. It is probable, as Mr. Rowning[[18a]] observes, that this notion was derived from them, by the Greeks: But the opinion that the sun[sun] stood still in the centre, while the whole heavens moved around it, was the prevailing one, until Copernicus, by the establishment of his system, restored the ancient astronomy of the Pythagorean school.
