When shall we open our minds to the conviction that the ultimate reality of the world is neither matter nor spirit, is no definite thing, but a perspective? God is perspective and hierarchy; Satan's sin was an error of perspective. Now, a perspective is perfected by the multiplication of its viewpoints and the precision with which we react to each one of its planes. The intuition of higher values fertilizes our contact with the lesser ones, and love for what is near and small makes the sublime real and effective within our hearts.
