Unqualified belief

"Once knowledge is recognised as conditional, it becomes harder to use as an apology for violence. Unqualified belief in one's own truth system is deadly. It is not from uncertainty about one's own judgements, but from unswerving forms of conviction, unamenable to any flicker of doubt, that the world has most to fear." --Jacqueline Rose, "The Iron Rule" (LRB 31.07.08)
