former, when there is in man no Astral spirit beside the Plastic of the
soul itself, which is always inseparable from that which is rational.
Nor upon any other account can it be called Astral, but as it is liable
to that corporeal temperament which proceeds from the stars, or rather
from any material causes in general, as not being yet sufficiently
united with the divine body--that vehicle of divine virtue or power."
So he maintains that the Kabalistic three souls--Nephesh, Ruach,
Neschamah--originate in a misunderstanding of the true Platonic
doctrine, which is that of a threefold "vital congruity." These
correspond to the three degrees of bodily existence, or to the three
"vehicles," the terrestrial, the aerial, and the ethereal. The latter
is the augoeides--the luciform vehicle of the purified soul whose
irrational part has been brought under complete subjection to the
rational. The aerial is that in which the great majority of mankind
find themselves at the dissolution of the terrestrial body, and in which
the incomplete process of purification has to be undergone during long
ages of preparation for the soul's return to its primitive, ethereal
state. For it must be remembered that the preexistence of souls is a
distinguishing tenet of this philosophy as of the Kabala. The soul has
"sunk into matter." From its highest original state the revolt of its
irrational nature has awakened and developed successively its "vital
congruities" with the regions below, passing, by means of its "Plastic,"
first into the aerial and afterwards into the terrestrial condition.
Each of these regions teems also with an appropriate population which
never passes, like the human soul, from one to the other--"gods,"
"demons," and animals.* As to duration, "the shortest of all is that of
the terrestrial vehicle. In the aerial, the soul may inhabit, as they
define, many ages, and in the ethereal, for ever."
