Time exists in order that everything doesn’t happen all at once…and space exists so that it doesn’t all happen to you. - Susan Sontag

And it is not necessarily better to be moved. Sentimentality, notoriously, is entirely compatible with a taste for brutality and worse.

To an Israeli Jew, a photograph of a child torn apart in the attack on the Sbarro pizzeria in downtown Jerusalem is first of all a photograph of a Jewish child killed by a Palestinian suicide-bomber. To a Palestinian, a photograph of a child torn apart by a tank round in Gaza is first of all a photograph of a Palestinian child killed by Israeli ordnance. To the militant, identity is everything. And all photographs wait to be explained or falsified by their captions. During the fighting between Serbs and Croats at the beginning of the recent Balkan wars, the same photographs of children killed in the shelling of a village were passed around at both Serb and Croat propaganda briefings. Alter the caption, and the children’s deaths could be used and reused.

Someone who is permanently surprised that depravity exists, who continues to feel disillusioned (even incredulous) when confronted with evidence of what humans are capable of inflicting in the way of gruesome, hands-on cruelties upon other humans, has not reached moral or psychological adulthood.
