If I search my own life for instances of good or fine behavior I am not overwhelmed by an excess of choice. I did once, shivering with fear, take off my flak jacket in Sarajevo and lend it to an even more frightened woman who I was helping escort to a place of safety (I am not the only one who has been an atheist in a foxhole). I felt at the time that it was the least I could do for her, as well as the most. The people shelling and sniping were Serbian Christians, but then, so was she.
