But in the sense of common people, not all the universe is called body, but only such parts thereof as they can discern by the sense of feeling, to resist their force, or by the sense of their eyes, to hinder them from a farther prospect. Therefore in the common language of men, _air_, and _aerial substances_, use not to be taken for _bodies_, but (as often as men are sensible of their effects) are called _wind_, or _breath_, or (because the same are called in the Latin _spiritus_) _spirits_; as when they call that aerial substance, which in the body of any living creature gives it life and motion, _vital_ and _animal spirits_. But for those idols of the brain, which represent bodies to us, where they are not, as in a looking-glass, in a dream, or to a distempered brain waking, they are, as the apostle saith generally of all idols, nothing; nothing at all, I say, there where they seem to be; and in the brain itself, nothing but tumult, proceeding either from the action of the objects, or from the disorderly agitation of the organs of our sense. And men, that are otherwise employed, than to search into their causes, know not of themselves, what to call them; and may therefore easily be persuaded, by those whose knowledge they much reverence, some to call them _bodies_, and think them made of air compacted by a power supernatural, because the sight judges them corporeal; and some to call them _spirits_, because the sense of touch discerneth nothing in the place where they appear, to resist their fingers: so that the proper signification of _spirit_ in common speech, is either a subtle, fluid, and invisible body, or a ghost, or other idol or phantasm of the imagination. But for metaphorical significations, there be many: for sometimes it is taken for disposition or inclination of the mind; as when for the disposition to controul the sayings of other men, we say, _a spirit of contradiction_; for _a disposition to uncleanness_, _an unclean spirit_; for _perverseness_, _a froward spirit_; for _sullenness_, _a dumb spirit_; and for _inclination to godliness and God’s service_, _the Spirit of God_: sometimes for any eminent ability or extraordinary passion, or disease of the mind, as when _great wisdom_ is called _the spirit of wisdom_; and _madmen_ are said to be _possessed with a spirit_.
