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 chosen 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.
Aldous Huxley, The Devils of Loudon
