But perhaps it may be asked as well concerning Brutes as rational Creatures, and of their Plants and Trees too, whether they are proportionably [The bigneſs of their Creatures not rightly gueſt at by the bigneſs of the Planets.] larger or leſs than ours. For if the Magnitude of the Planets was to be the Standard of their meaſure, there would be Animals in Jupiter ten or fifteen times larger than Elephants, and as much longer than our Whales, and then their Men muſt be all Giants in reſpect to us. Now tho’ I don’t ſee any ſo great Abſurdity in this as to make it impoſſible, yet there is no reaſon to think it is really ſo, ſeeing Nature has not always ty’d her ſelf to thoſe Rules which we have thought more convenient for her: For example, the Magnitude of the Planets is not anſwerable to their diſtances from the Sun; but Mars, tho’ more remote, is far leſs than Venus: and Jupiter turns round his Axis in ten Hours, when the Earth which is much leſs than him, ſpends 24. But ſince Nature, perhaps ſome will ſay, has not obſerved ſuch a Regularity in the proportion of Things, for ought we know there may be only a Race of Pygmies about the Bigneſs of Frogs and Mice, poſſeſs’d of the Planets. But I ſhall ſhow that this is very improbable by and by. [In the Planets are ſorts of rational Creatures as well as here.] There may ariſe another Queſtion, whether there be in the Planets but one ſort of rational Creatures, or if there be not ſeveral ſorts poſſeſſed of different degrees of Reaſon and Senſe. There is ſomething not unlike this to be obſerved among us. For to paſs by thoſe who have human Shape (altho’ ſome of them would very well bear that Enquiry too) if we do but conſider ſome ſorts of Beaſts, as the Dog, the Ape, the Beaver, the Elephant, nay ſome Birds and Bees, what Senſe and Underſtanding they are maſters of, we ſhall be forced to allow, that Man is not the only rational Animal. For we diſcover ſomewhat in them of Reaſon independent on, and prior to all Teaching and Practice.
