5. Though the Devil being corporeal should have entred into the body of the Serpent, yet by no motion that could be made with or upon her organs, could they have been framed to have uttered an articulate sound, because they were not fitted for that purpose, but only to have made a sibilation or hissing. For in Instruments that are artificial, the several sounds and tunes made by them, are but agreeable to the diversity of their parts and their several compactions; so an Harp cannot (when made) be ordered to give forth a sound like a Trumpet, nor the noise of a pair of Organs; nor on the contrary: and if any of their parts be wanting, defective or broken, then the orderly sound and Musick is spoyled. And though a Parret or Paraquet may by vocal and external teaching be brought to learn and speak some words; yet it is not by the teachers entring into her belly, but by his outward, vocal teaching, whereby her senses and phantasie are audibly wrought upon, and not otherwise. But in this action ascribed unto Satan, he is not supposed to be able to speak articulately, nor to have taught the Serpent vocally and audibly, which if he could have done, yet were not her organs capable of any such matter; and therefore it had been more subtilty in the Devil rather to have chosen a Parret than a serpent. The only objection worth taking notice of that _Pererius_ bringeth against the sound and reasonable opinion of learned _Cajetan_, is this: That _Adam_ and _Evah_ being in the state of innocency could not be wrought upon by an interiour tentation, because that neither the sensitive appetite nor the phantasie were corrupted; and therefore Satan could not internally work upon them, and therefore that the whole tentation must be extrinsecal. To which we return this sufficient reply. [Sidenote: _Reas. 1._] 1. It is but a bare assertion without any proof at all, and he doth but only shelter it under the authority of S. _Austin_ and _Gregory_, whose authority in many other matters he doth often reject when they agree not with his humour, end and interest. But however they are but _testimonia humana_; and we are not to regard what the Men are that do speak, so much as to consider the weight and reason of what they do speak. [Sidenote: _Reas. 2._]
