This external Speech is so excellent, that though it con∣sist but of wind, which is Air striking against the Epiglottis, mo∣difi'd and articulated by the tongue, lipps, palate, and teeth; yet 'tis the interpreter of the reasonable soul, according to whose example 'tis equally receiv'd into all the ears of the Auditors. When this Speech is true, 'tis a sign of the mind's conception, and as natural and peculiar to man as Reason it self, one of whose goodliest priviledges it is. Besides, man being born to live in so∣ciety needed not onely Reason to guide himself, but also Speech, to govern others, which likewise hath more power over Souls, inclining and turning them as it pleases.
The Second said, Some Animals are perfectly mute, as worms and Snails; others render some sound, as Flyes, Grashoppers, though 'tis onely that of their wings; and some have voice, as all perfect animals, amongst whom man hath the particular ad∣vantage of Speech. For sound is a Collision of Air between two solid bodies. Voice is a sound render'd by the mouth of an Ani∣mal to express its affections. But Speech is a voice which signi∣fies by institution, and is call'd a verb if it signifie time; other∣wise a noun. As it signifies by institution 'tis distinguish'd from the voice which is a natural sign, and hath some correspondence with the thing signifi'd. So the hoarse voice of one angry per∣fectly represents the inundation and tempest of the Spirits in this Passion. The lowness and mildness of a sad and afflicted mans voice represents the effect of sadness, which is to compress the Heart and Arteries; for these organs being coarcted, the voice be∣comes more slender; as appears in Women, fat people, chil∣dren, and eunuchs. The Lover's interrupted speech betrayes the inequality of his mind. But words are signes without any refer∣ence to the thing signifi'd, depending onely on the Will of those who first gave names to things. For if they were natural signes, they would be understood by all the world, and be every where the same. But though 'tis not natural, but acquir'd by precepts and use, specially by the hearing, whnce people deaf by nature are also dumb; yea, 'tis very peculiare to man. Wherefore Speech is improperly, figuratively, artificially, or else miraculously ascrib'd to other things; as when The Heavens are said to declare the glory of God, one deep to call on another, &c. When Balaams Ass spoke, 'twas by Miracle. But when Simon Magus's dog spoke to Saint Peter, 'twas by operation of the Devil; as also what is reported of the two Pigeons, the Oke at Dodona, Achilles's Horse, the keel of Argo, and that Elm of the Gymnosophists mention'd by Philostratus to have saluted Apollonius at his arrival, as the River Causus bid Pythagoras good-morrow. But Speech properly belongs onely to man; other creatures are incapable of it, both because they want Reason (which is the principle of it) and organs, which are a tongue, a palate, teeth, and lipps, all rightly proportion∣ated for the articulation of voice; for man's tongue alone is soft, large, moveable and loose; to which qualities those of Pies and Parrots come nearest.
