“Enq: Still you can hardly escape the charge of having invented a new division of man’s spiritual and psychic constituents; for no philosopher speaks of them, though you believe that Plato does.
Theo: And I support the view. Besides Plato, there is Pythagoras, who also followed the same idea.
“Plato and Pythagoras”, says Plutarch, “distribute the soul into two parts, the rational (noetic) and irrational (agnoia); that that part of the soul of man which is rational is eternal; for though it be not God, yet it is the product of an eternal deity, but that part of the soul which is divested of reason (agnoia) dies.”
The modern term Agnostic comes from Agnosis, a cognate word. We wonder why Mr. Huxley, the author of the word, should have connected his great intellect with “the soul divested of reason” which dies? Is it the exaggerated humility of the modern materialist?
He described the Soul as a self-moving Unit (monad) composed of three elements, the Nous (Spirit), the phren (mind), and thumos (life, breath or the Nephesh of the Kabalists) which three correspond to our “Atma-Buddhi”, (higher Spirit-Soul), to Manas (the Ego), and to Kama-rupa in conjunction with the lower reflection of Manas.
That which the Ancient Greek philosophers termed Soul, in general, we call Spirit, or Spiritual Soul, Buddhi as the vehicle of Atma (the Agathon, or Plato’s Supreme Deity).
The fact that Pythagoras and others state that phren and thumos are shared by us with the brutes, proves that in this case the lower Manasic reflection (instinct) and Kama-rupa (animal living passions) are meant.
And as Socrates and Plato accepted the clue and followed it, if to these five, namely, Agathon (Deity or Atma), Psuche (Soul in its collective sense), Nous (Spirit or Mind), Phren (physical mind), and Thumos (Kama-rupa or passions) we add the eidolon of the Mysteries, the shadowy form of the human double, and the physical body, it will be easy to demonstrate that the ideas of both Pythagoras and Plato were identical with ours.
Even the Egyptians held to the septenary division. In its exit, they taught, the Soul (Ego) had to pass through its seven chambers, or principles, those it left behind, and those it took along with itself.
The only difference is that, ever bearing in mind the penalty of revealing Mystery-doctrines, which was death, they gave out the teaching in a broad outline, while we elaborate it and explain it in its details.
But though we do give out to the world as much as is lawful, even in our doctrine more than one important detail is withheld, which those who study the esoteric philosophy and are pledged to silence, are alone entitled to know.”
