Such a Prothesis can scarce be called less than an ocular Revelation, not only shewing us how reasonable it is to expect a future Life, but as it were, pointing out to us the Business of an Eternity, and what we may with the greatest Confidence expect from the eternal Providence, dignifying our Natures with something analogous to the Knowledge we attribute to Angels; from whence we ought to despise all the Vicissitudes of adverse Fortune, which make so many narrow-minded Mortals miserable. _I am now, &c._ LETTER the NINTH. _Reflections, by Way of_ General Scolia, _of Consequences relating to the Immortality of the Soul, and concerning Infinity and Eternity._ _SIR_, This my last Letter to you, I mean my final astronomical one, I propose as a _General Scolia_ to the rest, the principle Matter being Reflections upon what is gone before, with some Conclusion naturally following or appendant to what has been already said; but which, I could not in any other Place, so properly remark to you. The Probability of the foregoing Conjectures, chiefly built upon very distant Observations, shew an apparent Necessity for some other kind of Doctrine permitted by Providence, to give Mankind a Knowledge of their Immortality and Dependance upon it, in the first Ages of the World. And for the same Reason it evidently appears, that the ancient Philosophers had it not in their Power to prove a supream _Being_ and Director of all Things this Way. And yet, as by a Sort of Instinct, or natural Reason, and Consciousness of a _good Principle_, we see how many noble Steps they made towards it, and was convinc'd at last of this _great Truth_, that since there was a _Mind_ in so imperfect a Creature as Man, the _perfect Universe_, which comprehended all Things, could not possibly be without one; and as Sir _Isaac Newton_ has justly observed in his _Principia_, "If every Particle of Space be _always_, and every individual Moment of Duration _every where_; surely the Maker and Lord of all Things, cannot be _never_ and _no where_." To make manifest the infinite Empire and Agency of God, from celestial Motion, became the Task, but of very late Years; and I can't help being of Opinion, that by means of these primary Bodies, only, we shall at length be able to trace the greater Circulations, and Laws of Nature, to their real original and fountain Head.
