What would it be like, I wonder, to live in a world so morally simple, so neat and tidy, so devoid of tragic clashes, so orderly, with its heroes and villains, its Children of Light and its Children of Darkness? I really wouldn’t know. Because the world I inhabit is one permeated by ambiguity and people with mixed motives who are often (usually?) torn between competing moral considerations and imperatives, not a world divided between the absolutely good and the absolutely evil. The line between good and evil doesn’t run between East and West, or North and South, or white and black, or Israel and Palestine. It runs right through every human heart. Or at least most hearts.
