Insight cannot be taken back. You cannot return to the moment you were in before.

Though I have never thought of myself as a book collector, there are shelves in our house browsed so often, on so many rainy winter nights, that the contents have seeped into me as if by osmosis.

We have a number of very powerful women in the world now - Mrs. [Angela] Merkel, who the Germans call Mutti. What did we call Mrs. [Margaret] Thatcher? When she was minister of education, she stopped the children's free school milk. This may sound quaint, but after the war we were such a malnourished nation that part of the founding of the welfare state were public health initiatives. Every little schoolchild got milk. Mrs. Thatcher stopped it. They called her "Maggie Thatcher, milk snatcher."

For me, it is about using everything that is there and using the gaps in the record, figuring out why the gaps might be there. And then when you move on to the level of what historians said, laying the interpretations side by side. You also have to look back at the documents and make your own judgments. What the record says and what people say about it. A novelist can fill the gaps in a way that a biographer cannot.

To a Brit of my generation, one of the most objectionable things about [Margaret] Thatcher is her falsity. She is a total construct. For one thing, she had a made-over accent.

What [Margaret Thatcher] made a play for was the acquisitive: our greedy nature. She set aside other things like an identification with community, altruism. The only collective that she understood was: Rally around and slay the enemy.

It is better not to try people, not to force them to desperation. Make them prosper; out of superfluidity, they will be generous. Full bellies breed gentle manners. The pinch of famine makes monsters.
