To the fanatical believer physical and spiritual suffering is beside the point, compared with salvation. That is why, to him, everything happening around him is irrelevant, a mirror-image, a mere will-o'-the-wisp. … I can really never get shot of them, the fanatics. Whether they appear as religious fanatics or vegetarian fanatics makes no odds. They're catastrophic people. These types whose whole cast of mind as it were looks beyond mere human beings toward some unknown goal. The terrible thing is the great power they often wield over their fellow human beings. Apart from the fact that I believe they suffer like the very devil, I've no sympathy for them.
