For fifteen centuries the religion of the Western world has been Christianity, Western Christianity, and there is no other religion now known or even imaginable that could take its place. But it is simply an historical fact, which we must deplore but cannot change, that only a small part of our population today, 12 or 15 per cent., really believes that Christ was the son of God, that the soul is immortal, and that our sins will be punished in a future life. That means that the religious instinct, which is a part of our nature, finds in the majority of our people no satisfaction in an unquestioning faith; so that those frustrated instincts are available for exploitation by any halfway clever scoundrel, as the shysters and punks who now occupy the majority of our pulpits well know. When faith is lost, what Pareto calls the religious residue in a people becomes its most vulnerable point, its Achilles heel. It is the unsatisfied need for an unquestioning faith in a superior power.
