Quotes:Agnoia

Blavatsky, Helena Petrovna

Agnoia. “Divested of reason”, lit., “irrationality”, when speaking of the animal Soul. According to Plutarch, Pythagoras and Plato divided the human soul into two parts (the higher and lower manas) — the rational or noëtic and the irrational, or agnoia, sometimes written “annoia”.
