The second doctrine of the Perennial Philosophy — that it is possible to know the Divine Ground by a direct intuition higher than discursive reasoning — is to be found in all the great religions of the world. A philosopher who is content merely to know about the ultimate Reality — theoretically and by hearsay — is compared by Buddha to a herdsman of other men's cows. Mohammed uses an even homelier barnyard metaphor. For him the philosopher who has not realized his metaphysics is just an ass bearing a load of books. Christian, Hindu, Taoist teachers wrote no less emphatically about the absurd pretensions of mere learning and analytic reasoning.

Something that had been a single cell, a cluster of cells, a little sac of tissue, a kind of worm, a potential fish with gills, stirred in her womb and would one day become a man — a grown man, suffering and enjoying, loving and hating, thinking, remembering, imagining. And what had been a blob of jelly within her body would invent a god and worship; what had been a kind of fish would create, and, having created, would become the battleground of disputing good and evil; what had blindly lived in her as a parasitic worm would look at the stars, would listen to music, would read poetry.

No man can concentrate his attention upon evil, or even upon the idea of evil, and remain unaffected. To be more against the devil than for God is exceedingly dangerous. Every crusader is apt to go mad. He is haunted by the wickedness which he attributes to his enemies; it becomes in some sort a part of him.
Possession is more often secular than supernatural. Men are possessed by their thoughts of a hated person, a hated class, race or nation. At the present time the destinies of the world are in the hands of self-made demoniacs - of men who are possessed by, and who manifest, the evil they have chose to see in others. They do not believe in devils; but they have tried their hardest to be possessed - have tried and been triumphantly successful. And since they believe even less in God than in the devil, seems very unlikely that they will ever be able to cure themselves of their possession. Concentrating his attention upon the idea of a supernatural uncommon among secular demoniacs. But his idea of good was also supernatural and metaphysical, and in the end it saved him.
