Bodies which are smooth and polish'd, as Looking-Glasses and the like; so that those Glasses when ground after a particular manner will Collect so much Light as to kindle a Fire. So that Spirit which comes by the Command of God, do's at all times act upon all Creatures, in some of which notwithstanding, there appears no Impression of it, but the reason of that is, because of their Incapacity into whom it is infus'd; of which kind are things inanimate which are fitly represented in this similitude, by the thin Air. There are another sort again; in which there does appear something of it, as Vegetables and the like, which are represented by the thick Bodies we mention'd, which are not polish'd. And then lastly, there are others, (represented by those Glasses, in our last comparison) in which the impressions of this Spirit are visible, and such we reckon all sorts of Animals. But then, as these smooth and polish'd Bodies which are of the same figure with the Sun [i.e. Spherical] do receive the Rays in a more plentiful manner than any other whatsoever, so also do some Animals receive the Influence of that Spirit more than others, because they are more like to that Spirit and are form'd after his Image: such is Man particularly, which is hinted before where 'tis said that _God made Man after his own Image_[19]. Sec. 7. Now, when this Form prevails to such a degree that all others are nothing before it, but it remains alone, so as to consume, with the glory of its Light, whatsoever stands; in it's way; then it is properly compared to those Glasses, which reflect Light upon themselves, and burn every thing else; But this is a degree which is peculiar to the Prophets. Sec. 8. But to return, and speak something more fully concerning the Opinion of those who account for this kind of generation; They tell us, that as soon as this Spirit was join'd to the Receptacle, all the other powers immediately, by the Command of God, submitted themselves to it. Now, opposite to this Receptacle, there arose another Bubble divided into three Receptacles by thin membranes, with passages from one to the other, which were fill'd with an aerial substance, not much unlike that which was in the first Receptacle, only the first was something finer; and in each of these three Ventricles,which were all taken out of one, were plac'd some of those Faculties, which were subject to this governing Spirit, and were appointed to take care of their respective Stations, and to communicate every thing, both great and small, to that Spirit, which we told you before was plac'd in the first Receptacle. Right against this Receptacle, opposite to the second, there arose another third Bubble, fill'd with an aerial substance, which was grosser than that which was in the other two; this was made for the Entertainment and preservation of some other of the inferior Faculties.
