But I perceive I am got ſomewhat too far: Let us firſt enquire a little concerning the bodily Senſes of theſe Planetary Perſons; for without ſuch, neither will Life be any Pleaſure to them, nor Reaſon of any Uſe. And I think it very probable, that all their Animals, as well their Beaſts as rational Creatures, are like ours in all that relates to the Senſes: For without the Power of Seeing we ſhould find it impoſſible for Animals to provide Food for themſelves, or be ſore-warn’d of any approaching Danger, ſo as to guard themſelves from it. So that where-ever we plant any Animals, except we wou’d have them lead the Life of Worms or Moles, we muſt allow them Sight; than which nothing can conduce more either to the Preſervation or Pleaſure of their Lives. Then if we conſider the wonderful Nature of Light, and the [Sight.] amazing Artifice in the fit framing the Eye for the Reception of it, we cannot but ſee that Bodies ſo vaſtly remote could not be perceived by us in their proper Figures and juſt Diſtances, any other way than by Sight. For this Senſe, and all others that we know of, muſt proceed from an external Motion. Which in the ſenſe of Seeing muſt come either from the Sun, the fix’d Stars, or Fire: whoſe Particles being put into a very quick Motion, communicate it to the Celeſtial Matter about, whence ’tis convey’d in a very ſhort time to the moſt diſtant parts, juſt like Sound through the Air. If it were not for this Motion of the intermediate Ætherial Matter, we ſhould be all in Darkneſs, and have Sight neither of Sun nor Stars, nor any thing elſe, for all other Light muſt come to us by Reflection from them. This Motion perceived by the Eyes is called Light. And the nice Curioſity of this Perception is admirable, in that it is cauſed by the ſmalleſt Particles of the luminous Body brought to us by that fine Matter, which at the ſame time determine the Coaſt from whence the Motion comes; and in that all theſe different Roads of Motion, theſe Waves croſſing and interfering with one another, are yet no hindrance to every one’s free Paſſage. All theſe Things are ſo wiſely, ſo wonderfully contrived, that it’s above the Power of humane Wit, to invent or frame any thing like them; nay, it is very difficult ſo much as to imagine and comprehend them. For what can be more amazing, than that one ſmall Part of the Body ſhould be ſo deviſed and framed, as by its means to ſhow us the Shape, the Poſition, the Diſtance, and all the Motions, nay, and all the Colours, of a Body that is far remote from us, that it may appear the more diſtinct? And then the artful Compoſition of the Eye, drawing an exact Picture of the Objects without it, upon the concave Side of the Choroides, is even above all Admiration, nor is there any Thing in which God has more plainly manifeſted his excellent Geometry. And theſe Things are not only contriv’d and fram’d with ſo great Wiſdom and Skill, as not to admit of better, but to any one that conſiders them
