It may be supposed “that the souls of brutes, being but so many eradiations or effuxes from that source of life above, are, as soon as ever those organized bodies of theirs, by reason of their indisposition, become uncapable of being further acted upon by them, then to be resumed again and retracted back to their original head and fountain.  Since it cannot be doubted but what creates anything out of nothing, or sends it forth from itself, by free and voluntary emanation, may be able either to retract the same back again to its original source, or else to annihilate it at pleasure.  And I find that there have not wanted some among the Gentile philosophers themselves who have entertained this opinion, whereof Porphyry is one, λύεται ἑκάστη δύναμις ἀλογος εἰς τὴν ὅλην ζωὴν τοῦ πάντος.”  Cudworth, i. 35.
