§ 55. This put him to a great deal of trouble, which made him begin to consider with himself, what were the Consequences which did follow from each of these Opinions, and that perhaps they might be both alike. And he perceiv'd, that if he held that the World was created in Time, and existed after a total Privation, it would necessarily follow from thence, that it could not exist of it self, without the help of some Agent to produce it. And that this Agent must needs be such an one as cannot be apprehended by our Senses; for if he should be the Object of Sense, he must: be _Body_, and if _Body_, then a Part of the World, and consequently a Created Being; such an one, as would have stood in need of some other Cause to create him: and if that second Creator was _Body_, he would depend upon a, third, and that third upon upon a fourth, and so _ad infinitum_, which is absurd. Since therefore the World stands in need of an incorporeal Creator: And since the Creator thereof is really incorporeal, 'tis impossible for us to apprehend him by any of our Senses; for we perceive nothing by the help of them, but _Body_, or such Accidents as adhere to _Bodies_: And because he cannot be perceiv'd by the Senses, it is impossible he should be apprehended by the Imagination; for the Imagination does only represent to us the Forms of things in their absence, which we have before learn'd by our Senses. And since he is not _Body_, we must not attribute to him any of the Properties of _Body_; the first of which is Extension, from which he is free, as also from all those Properties of Bodies which flow from it. And seeing that he is the Maker of the World, doubtless he has the Sovereign Command over it. _Shall not he know it, that created it? He is wise, Omniscient!_
§ 56. On the other side, he saw that if he held the Eternity of the World, and that it always was as it now is, without any Privation before it; then it would follow, that its Motion must be Eternal too; because there could be no Rest before it, from whence it might commence its Motion. Now all Motion necessarily requires a Mover; and this Mover must be either a Power diffus'd through the Body mov'd, or else through some other Body without it, or else a certain Power, not diffus'd or dispers'd through any Body at all. Now every Power which passeth, or is diffus'd, through any Body, is divided or doubled. For Instance; The _Gravity_ in a Stone, by which it tends downwards, if you divide the Stone into two parts, is divided into two parts also; and if you add to it another like it, the Gravity is doubled. And if it were possible to add Stones _in infinitum,_ the Gravity would increase _in infinitum_ too. And if it were possible, that that Stone should grow still bigger, till it reach'd to an infinite Extension, the Weight would increase also in the same proportion; and if on the other side, a Stone should grow to a certain size, and stop there, the Gravity would also increase to such a pitch, and no farther. Now it is demonstrated, that all Body must necessarily be finite; and consequently, that Power which is in Body is finite too. If therefore we can find any Power, which produces an Infinite Effect, 'tis plain that it is not in Body. Now we find, that the Heav'n is mov'd about with a Perpetual Motion, without any Cessation. Therefore if we affirm the Eternity of the World, it necessarily follows that the Power which moves it, is not in its own Body, nor in the other Exterior Body; but proceeds from something altogether abstracted from Body, and which cannot be describ'd by Corporeal Adjuncts or Properties. Now he had learn'd from his first Contemplation of the Sublunary World, that the true Essence of Body consisted in its _Form,_ which is its Disposition to several sorts of Motion; but that Part of its Essence which consisted in _Matter_ was very mean, and scarce possible to be conceiv'd; therefore the Existence of the whole World consists in its Disposition to be mov'd by this Mover, who is free from Matter, and the Properties of Body; abstracted from every thing which we can either perceive by our Senses, or reach by our Imagination. And since he is the Efficient Cause of the Motions of the Heavens, in which (notwithstanding their several kinds) there is no difference, no Confusion, no Cessation; without doubt he has a Power over it, and a perfect Knowledge of it.
