attentively, they ſeem to be of ſuch a Nature as not to allow any other Method. For it’s impoſſible that Light ſhould repreſent Objects to us at ſo vaſt a diſtance, except by ſuch an intervening Motion; and it’s as impoſſible that any other Compoſition of the Eye ſhould be equally fitted to the Reception of ſuch Impreſſions. So that I cannot but think them greatly miſtaken, that maintain theſe Things might have been contrived many other Ways. It’s likely then, and credible, that in theſe Things the Planets have an exact correſpondence with us, and that their Animals have the ſame Organs, and uſe the ſame way of Sight that we do. They muſt have Eyes therefore, and two at leaſt we muſt grant them, otherwiſe they would not perceive thoſe Things cloſe to them, nor hardly be able to walk about with Safety. And if we muſt allow them to all Animals for the Preſervation of their Life, how much more muſt they that make more, and more noble Uſes of them, not be deprived of the Bleſſing of ſo advantageous Members? For by them we view the various Flowers, and the elegant Features of Beauty: with them we read, we write, we contemplate the Heavens and Stars, and meaſure their Diſtances, Magnitudes, and Journeys: which how far they are common to the Inhabitants of thoſe Worlds with us, I ſhall preſently examine. But firſt I ſhall enquire whether now we have given them one, we ought alſo to give them the other [Hearing.] four Senſes. And indeed as to Hearing many Arguments perſwade me to give it a Share in the Animals of thoſe new Worlds. For ’tis of great conſequence in defending us from ſudden Accidents; and, eſpecially when Seeing is of no uſe to us, it ſupplies its Place, and gives us ſeaſonable warning of any imminent Danger. Beſides, we ſee many Animals call their Fellow to them with their Voice, which Language may have more in it than we are aware of, tho’ we don’t underſtand it. But if we do but conſider the vaſt Uſes and neceſſary Occaſions of Speaking on the one ſide, and Hearing on the other, among thoſe Creatures that make uſe of their Reaſon, it will ſcarce ſeem credible that two ſuch uſeful, ſuch excellent Things were deſigned only for us. For how is it poſſible but that they that are without theſe, muſt be without many other Neceſſaries and Conveniences of Life? Or what can they have to recompenſe this Want? Then, if we go ſtill farther, and do but meditate upon the neat and frugal Contrivance of Nature in making the ſame Air, by the drawing in of which we live, by whoſe Motion we ſail, and by whoſe Means Birds fly, for a Conveyance of Sound to our Ears; and this Sound for the Conveyance of another Man’s Thoughts to our Minds: Can we ever imagine that ſhe has left thoſe other Worlds deſtitute of ſo vaſt [A Medium to convey Sound to the Ears.] Advantages? That they don’t want the Means of them is certain, for their having Clouds in Jupiter puts it paſt doubt that they have Air too; that being moſtly formed of the Particles of Water
