Amos Oz on Fanaticism

"The essence of fanaticism lies in the desire to force other people to change—the common inclination to improve your neighbor, mend your spouse, engineer your child, or straighten up your brother, rather than let them be. The fanatic is a most unselfish creature. The fanatic is a great altruist.

In fact, often the fanatic is more interested in you than in himself. He wants to save your soul, he wants to redeem you, he wants to liberate you from sin, from error, from smoking, from your faith or from your faithlessness, he wants to improve your eating habits, or to cure you of your drinking or voting habits. The fanatic cares a great deal for you; he is always either falling on your neck because he truly loves you or else he is at your throat in case you prove to be unredeemable. And, in any case, topographically speaking, falling on your neck and being at your throat are almost the same gesture.

One way or another, the fanatic is more interested in you than in himself, for the simple reason that the fanatic has very little self or no self at all."
