Part 91

Footnote 379:

Mr. Maclaurin having noticed that the Author of Nature has made it impossible for us to have any communication, from this earth, with the other great bodies of the universe, in our present state; and after remarking on some phænomena in the planetary system, makes the following just reflections, which correspond with those expressed by Dr. Rittenhouse, in the concluding pages of his Oration:—“From hence, as well as from the state of the moral world and many other considerations, we are induced to believe, that our present state would be very imperfect without a subsequent one; wherein our views of nature, and of its great Author, may be more clear and satisfactory. It does not appear to be suitable to the wisdom that shines throughout all nature, to suppose that we should see so far, and have our curiosity so much raised concerning the works of God, only to be disappointed in the end. As man is undoubtedly the chief being upon this globe, and this globe may be no less considerable, in the most valuable respects, than any other in the solar system, and this system, for ought we know, not inferior to any other in the universal system; so, if we should suppose man to perish, without ever arriving at a more complete knowledge of nature, than the very imperfect one he attains in his present state; by analogy, or parity of reason, we might conclude, that the like desires would be frustrated in the inhabitants of all the other planets and systems; and that the beautiful scheme of nature would never be unfolded, but in an exceedingly imperfect manner, to any of them. This, therefore, naturally leads us to consider our present state as only the dawn or beginning of our existence, and as a state of preparation or probation for farther advancement: which appears to have been the opinion of the most judicious philosophers of old. And whoever attentively considers the constitution of human nature, particularly the desires and passions of men, which appear greatly superior to their present objects, will easily be persuaded that man was designed for higher views than of this life. Surely, it is in His power to grant us a far greater improvement of the faculties we already possess, or even to endow us with new faculties, of which, at this time, we have no idea, for penetrating farther into the scheme of nature, and approaching nearer to Himself, the First and Supreme Cause.”

The striking coincidence of the foregoing sentiments, with those expressed by Dr. Rittenhouse; in addition to the sublimity of the conceptions; the cogency of the argument; and the weight of the concurring opinions of two so great astronomers and mathematicians, on a subject of such high importance to mankind; all plead an apology for the length of this extract, from Maclaurin’s Account of Sir Isaac Newton’s Philosophical Discoveries.

Such were the pious reflections of a Christian Philosopher; the sublime sentiments of an eminently distinguished Astronomer.

Should it be enquired: What was the system of Philosophy, to which Dr. Rittenhouse adhered? though such a question can scarcely be anticipated, after what has been already said; the answer may be furnished in a few words: He was a thorough and zealous disciple of the Newtonian school. He early embraced, and perseveringly cultivated, “the Philosophy of Newton;” which “disdains to make use of subterfuges,” which “is not reduced to the necessity of using them, because it pretends not to be of nature’s privy council;” while “other systems of philosophy have ever found it necessary to conceal their weakness and inconsistency, under the veil of unintelligible terms and phrases, to which no two mortals perhaps ever affixed the same meaning.”

Footnote 381:

The words between inverted commas, in the above paragraph, are quoted from Rittenhouse’s Oration.

Notwithstanding the fanciful theories introduced into physics by Descartes, concerning his materia subtilis and vortices, and his doctrine of a plenum, which were prostrated by the general adoption of the Newtonian system, the improvements that had been made in the mathematical sciences and some other branches of physics, by the Cartesian system, produced a great revolution in the species of philosophy which till then prevailed. The philosophy of Descartes, erroneous and defective as, in some particulars, it was found to be, triumphed, by its superior energy, over the crude and feeble systems of the schools. The peripatetic doctrines which had revived in Europe, after she emerged from the barbarism and gloom that succeeded the final declension of the Roman empire, continued from that period to be the prevailing philosophy; and tinctured, also, the whole mass of the scholastic theology: but the systems of Descartes first dissipated most of the useless subtleties of the schoolmen; while the truths brought to light by the philosophy of Newton, still further exposed their absurdities. According to Dr. Reid (in his Essays on the intellectual and active powers of Man,) even the most useful and intelligible parts of the writings of Aristotle himself had, among them, become neglected; and philosophy was reduced to an art of speaking learnedly and disputing subtilely, without producing any invention of utility in the affairs of human life. “It was,” to use the language of Dr. Reid, “fruitful in words, but barren of works; and admirably contrived for drawing a veil over human ignorance, and putting a stop to the progress of knowledge, by filling men with a conceit that they knew every thing. It was very fruitful also in controversies; but, for the most part, they were controversies about words, or things above the reach of the human faculties.”

With Newton, too, our Philosopher entertained the most exalted conceptions of the Deity. He did not imagine, as his illustrious predecessor was unjustly charged with having done, that infinite space is an attribute of the Deity; that He is present in all parts of space, by diffusion; but, like that great man, he did believe, that the Deity endures from eternity to eternity, and is present from infinity to infinity; yet that He is not eternity or infinity, space or duration. For, says Dr. Rittenhouse, “Nothing can better demonstrate the immediate presence of the Deity in every part of space, whether vacant or occupied by matter, than Astronomy does. It was from an Astronomer St. Paul quoted that exalted expression, so often since repeated, ‘In God we live, and move, and have our being.’”

Footnote 382:

The celebrated Dr. Samuel Johnson has remarked, that “Leibnitz persisted in affirming that Newton called Space, Censorium Numinis, notwithstanding he was corrected, and desired to observe that Newton’s words were, QUASI Censorium Numinis. See Boswell’s Journal of a Tour to the Hebrides.

Footnote 383:

This concise, yet beautiful and expressive sentence, is contained in St. Paul’s address to the Athenians, cited in the 17th chapter of the Acts of the Apostles.

The terms of profound veneration, in which our Philosopher spoke, on all occasions, of the character of Newton, demonstrate most clearly his complete and undeviating attachment to the Principles of that astonishing man. Indeed, he appears to have taken him as his model; and, certainly, he resembled him much, in many points of character. Parallels have often been drawn between distinguished men; and in comparatively a few instances, a strong resemblance has been discovered, in some prominent features of character, between two or more persons. Yet the infinite variety of talent, that appears throughout the human race; the almost incredible difference in the grades of intellectual endowment, distinguishing the sons of men from each other; and the adventitious circumstances peculiar to each individual, which either direct or controul his conduct, and seem to mark his destiny in life; all these, taken together, produce such an endless diversity of character in the species, as to render it impracticable, if not absolutely impossible, to find any two men who greatly resemble each other in many particulars.

-----

Footnote 384:

A strong proof of this veneration will be found in Dr. Rittenhouse’s Oration, wherein he expresses himself in these remarkable words:—“It was, I make no doubt, by a particular appointment of Providence, that at this time the immortal Newton appeared.”

There are, nevertheless, so many circumstances founded on natural causes, that indicate an extraordinary similitude in the genius, disposition and principles of Rittenhouse, and his great Prototype; so many, moreover, of a singular nature, connected with events purely adventitious, wherein the condition, occupations and pursuits of these philosophers, with other eventual relations depending wholly on accident, resembled each other; that an interesting parallel, between them, might be attempted with no inconsiderable share of success.

In the course of these Memoirs, the Biographer of RITTENHOUSE has endeavoured to furnish a faithful representation of the Philosopher and of the Man. He was desirous of delineating his true character, in both points of view; that the world may be enabled to make a just estimate of the genius, the principles, and the conduct of a person, so celebrated in name. But, in order that the more correct judgment might be formed of his virtues and talents, and of the services he has rendered to society, it became necessary to describe the sphere in which he moved; so far, at least, as to present to view occasional sketches of the complexion of the Times in which he lived, and of some of the more prominent Characters who were his compatriots. The Memorialist has therefore conveyed to the mind of his reader some idea of the moral, political, and literary state of society, more particularly in the country of our Philosopher’s residence, within the same period. This rendered it proper to notice the rise, nature, and progress of certain Institutions, upon which science and the arts, with many of the benefits of civil polity, greatly depend; such as tend to diffuse useful knowledge throughout the community, to promote the general weal, and to meliorate the condition of the great family of mankind.

It has been already observed, that every individual in society is more or less closely connected with it, in various ways: and it is obvious, that an eminent citizen, one, especially, standing in relations of a public nature in the community of which he is a member, usually has his history and character so interwoven with those of his own times, that it is difficult to understand the former thoroughly, without possessing a competent knowledge of the latter. The Life of such a man as RITTENHOUSE could not, therefore, in many respects, be either well comprehended or duly estimated, unless there had been connected with it some account of men and things, to which his private pursuits and public employments were, directly or indirectly, related.
