Here it will be seen, we lose sight of the specific difference of the
two future vehicles--the ethereal is regarded as a sublimation of the
aerial. This, however, is opposed to the general consensus of Plato's
commentators. Sometimes the ethereal body, or augoeides, is appropriated
to the rational soul, or spirit, which must then be considered as a
distinct entity, separable from the lower soul. Philoponus, a Christian
writer, says, "that the Rational Soul, as to its energie, is separable
from all body, but the irrational part or life thereof is separable only
from this gross body, and not from all body whatsoever, but hath after
death a spirituous or airy body, in which it acteth--this I say is a
true opinion which shall afterwards be proved by us.... The irrational
life of the soul hath not all its being in this gross earthly body, but
remaineth after the soul's departure out of it, having for its vehicle
and subject the spirituous body, which itself is also compounded out of
the four elements, but receiveth its denomination from the predominant
part, to wit, Air, as this gross body of ours is called earthy from what
is most predominant therein."--Cudworth, "Intell. Syst." From the same
source we extract the following: "Wherefore these ancients say that
impure souls after their departure out of this body wander here up and
down for a certain space in their spirituous vaporous and airy body,
appearing about sepulchres and haunting their former habitation. For
which cause there is great reason that we should take care of living
well, as also of abstaining from a fouler and grosser diet; these
Ancients telling us likewise that this spirituous body of ours being
fouled and incrassated by evil diet, is apt to render the soul in this
life also more obnoxious to the disturbances of passions. They further
add that there is something of the Plantal or Plastic life, also
exercised by the soul, in those spirituous or airy bodies after death;
they being nourished too, though not after the same manner, as those
gross earthy bodies of ours are here, but by vapours, and that not by
