By the _Exterior Motions of the Planets_, we may believe their Exterior Shape is Spherical: for, it is to be observed, That all Exterior Actions are according to their Exterior Shape: but, by reason Vegetables and Minerals have not such sorts of Exterior Motions or Actions, as Animals; some Men are of opinion, they have not Sensitive Life; which opinion proceeds from a shallow consideration: neither do they believe the Elements are sensible, although they visibly perceive their Progressive Motions; and yet believe all sorts of Animals to have sense, only because they have Progressive Motions. CHAP. XXXI. Of the Sun, and Planets, and Seasons. The Sun, Moon, Planets, and all those glittering Starrs we see, are several sorts of that Man names _Elemental Creatures_: but Man, having not an infinite Perception, cannot have an infinite perceptive knowledg: for, though the Rational Perception is more subtil than the Sensitive; yet, the particular Parts cannot perceive much further than the Exterior Parts of Objects: but, Human Sense and Reason cannot perceive what the Sun, Moon, and Starrs are; as, whether solid, or rare; or, whether the Sun be a Body of Fire; or the Moon, a Body of Water, or Earth; or, whether the Fixed Starrs be all several Suns; or, whether they be other kinds or sorts of Worlds. But certainly, all Creatures do subsist by each other, because Nature seems to be an Infinite united Body, without _Vacuum_. As for the several Seasons of the Year, they are divided into Four Parts: but the several Changes and Tempers of the Four Seasons, are so various, altering every moment, as it would be an endless work, nay, impossible, for one Creature to perform: for, though the _Almanack-makers_ pretend to foreknow all the variations of the Elements; yet, they can tell no more than just what is the constant and set-motions; but not the variations of every Hour, or Minute; neither can they tell any thing, more than their Exterior Motions. CHAP. XXXII. Of Air corrupting Dead Bodies. Some are of opinion, _That Air is a Corrupter, and so a Dissolver of all dead Creatures, and yet is the Preserver of all living Creatures._ If so, Air hath an Infinite Power: but, all the reason I can perceive for this Opinion, is, That Man perceives, that when any Raw (or that we name _Dead_) _Flesh_, is kept from the air, it will not stink, or corrupt, so soon as when it is in the air: but yet it is well known, that extream cold air will keep Flesh from corrupting. Another Reason is, That a Flye entomb'd in _Amber_, being kept from air, the Flye remains in her Exterior Shape as perfectly as if she were alive.
