I think it's outrageous if a historian has a 'leading thought' because it means they will select their material according to their thesis.

Restorers of paintings and pottery follow a code of conduct in their work to distinguish the original material from what they are adding later.

I read round the subject, I make a skeleton outline, and then I start work in the relevant archives. During the marshaling of the material, I copy the material from each archive file across to the relevant chapter in the skeleton outline.

It was only after five years in the army, when I was having to do a very boring job in a very boring place, that I thought: 'Why not try writing a novel?' partly out of youthful arrogance and partly because there had been a long line of writers in my mother's family.

I am not someone who believes I am going to find a historical scoop.

It is this compulsion to look backwards at a time of crisis because one's got no idea of what lies ahead. There is a notion of security that somehow it must resemble the past. It's never going to. Just because we muddled through in the past doesn't mean we can automatically muddle through in the future.
