“Enq: Is it what we call Spirit and Soul, and the man of flesh?
Theo: It is not. That is the old Platonic division. Plato was an Initiate, and therefore could not go into forbidden details; but he who is acquainted with the archaic doctrine finds the seven in Plato’s various combinations of Soul and Spirit.
He regarded man as constituted of two parts – one eternal, formed of the same essence as the Absoluteness, the other mortal and corruptible, deriving its constituent parts from the minor “created” Gods.
Man is composed, he shows, of (1) A mortal body, (2) An immortal principle, and (3) A “separate mortal kind of Soul.” It is that which we respectively call the physical man, the Spiritual Soul or Spirit, and the animal Soul (the Nous and psuche).
This is the division adopted by Paul, another Initiate, who maintains that there is a physical body which is sown in the corruptible (astral soul or body), and a spiritual body that is raised in incorruptible substance.
Even James (iii. 15) corroborates the same by saying that the “wisdom” (of our lower soul) descendeth not from the above, but is terrestrial (“physical”, “demoniacal”, vide Greek text); while the other is heavenly wisdom.
Now so plain is it that Plato and even Pythagoras, while speaking but of three “principles”, give them seven separate functions, in their various combinations, that if we contrast our teachings this will become quite plain.”
