And people shutter their minds. What good are reports? History in a news account? Preselected at an editorial conference, digested and excreted by prejudice? Accounts you need seldom come from those who make history. Diaries, memoirs and autobiographies are subjective forms of special pleading. Archives are crammed with such suspect stuff."

"Enter no conflict against fanatics unless you can defuse them. Oppose a religion with another religion only if your proofs (miracles) are irrefutable or if you can mesh in a way that the fanatics accept you as god-inspired."
