14. (19). What about the souls of animals inferior to man? The
(rational) souls that have strayed so far as to descend into the bodies
of animals are nevertheless still immortal.[92] Souls of a kind other
(than rational souls), cannot proceed from anything else than the
living nature (of the universal Soul); and they necessarily are the
principles of life for all animals. The case is the same with the souls
that inhere in plants. Indeed, all souls have issued from the same
principle (the universal Soul), all have an individual life, and are
indivisible and incorporeal essences ("beings").
