“Man has two cognitive centers.  One is the nous, the organ suited for receiving God’s revelation which is then formulated by our reason, while the other is reason, which knows the tangible world around us.  With our nous we acquire knowledge of God, while with our reason we acquire knowledge of the world and the learning offered by the science of sensory things.”
