Dialogue: 0,0:00:04.27,0:00:07.45,Default,,0000,0000,0000,,And the reason was, \Nbecause when I was asked to do this,
Dialogue: 0,0:00:07.45,0:00:11.01,Default,,0000,0000,0000,,I'd just read, in one of the papers,\NI can't remember,

Dialogue: 0,0:00:18.32,0:00:20.36,Default,,0000,0000,0000,,And that's so wrong,
Dialogue: 0,0:00:20.36,0:00:24.30,Default,,0000,0000,0000,,that's such a fundamentally,\Nreactionary view of identity,
Dialogue: 0,0:00:24.30,0:00:26.40,Default,,0000,0000,0000,,and it's going to get us\Ninto all sorts of trouble.
Dialogue: 0,0:00:26.40,0:00:27.64,Default,,0000,0000,0000,,And so what I thought I'd do\N
