From these amazing Ideas of Space in general, and from the particular Distance of the Stars, which separates as it were, one System of Bodies from another, and by so prodigious an extent, as scarce to be suppos'd a temporal Task. I think it naturally follows, had we no other Way to prove it, or any other Reason to believe it, that the Soul must of Necessity be immaterial; for as this Space seems so impassible to Matter, as not to be undertaken and performed without the Loss of Ages, in a State only of Transmigration, we may well imagine, that Change of Place is not effected this Way, but by some other Virtue or Property, more immediate, if not instantaneous. I own next to _Annihilation_ is the State of Oblivion, and this Way we may solve all Difficulties with regard to our being sensible of such a Loss of Existence; but if we allow the Soul to be immaterial, it no longer has any thing to do with Space, but as operating by Reflection only, or the Faculty of Thinking; it may be like the Imagination where it pleases in a Moment. Objects of the Mind abstracted from the Senses of the Body, has no real or comparative Magnitude; that is, I would say, an Inch, a Foot, a Yard, a Mile, or a Million of Miles are all equally indefinite, and is thus prov'd; every finite Line is formed of an infinite Number of Points, and no finite Line can be solv'd into more. Thus if you will allow me the Expression, the Mind being magnified as all Objects are diminished, what seems impracticable in the natural State of Things, in an Ideal one, becomes very possible; that is, to make myself more intelligible, though we can hardly conceive, how any Being can pass from _Syrius_ to the Sun, by natural Laws in their proper State, yet if proportionally reduced by a new Modification of Ideas, to the Bigness of a Ball 6 Feet Diameter, and to be only 680 Miles asunder; the Thing is very comprehensive and easy. [Illustration: Plate XXXI.] [Illustration: Plate XXXII.] Hence Vision, Light, and Electrical Virtue, seem to be propagated with such Velocity, that nothing but God can possible be the Vehicle; and hence we may justly say with St. _Paul_, _Acts_ xvii, 28. _In him we live, in him we move, in him we have our Being._ It will further appear, from the foregoing Letters, that all the Stars and planetary Bodies within the finite View, are altogether but a very minute Part of the whole rational Creation; I mean that vast collective Body of habitable Beings, which I have endeavoured to demonstrate, are all govern'd by the same Laws, though variously revolving round one common Center, in which Center we may not impertinently venture to suppose the prime Agent of our Natures; or otherwise, the most perfect of all created Beings, illimitable in his Ideas and Faculties of Sensation particularly preside.
