I know quite well why I became a historian.... It was because dissension was frowned upon when I was a child: 'Don't argue, Claudia,' 'Claudia, you must not answer back like that.' Argument, of course, is the whole point of history. Disagreement; my word against yours; this evidence against that. If there were such a thing as absolute truth the debate would lose its lustre. I, for one, would no longer be interested.
