Often it's true that films just go right through us. You see the film, you might be entertained, and if it's not a great film, it loses its power very quickly. I think even simply acceptable books stay with us a lot longer.

When the father dies, he writes, the son becomes his own father and his own son. He looks at is son and sees himself in the face of the boy. He imagines what the boy sees when he looks at him and finds himself becoming his own father. Inexplicably, he is moved by this. It is not just the sight of the boy that moves him, not even the thought of standing inside his father, but what he sees in the boy of his own vanished past. It is a nostalgia for his own life that he feels, perhaps, a memory of his own boyhood as a son to his father.

Money's important. Everyone cares about money. And when you don't have money, money becomes the overriding obsession of your life.

I met Peter Brook, the theater director, who's been based in Paris for many years at the Bouffes du Nord. I admire him tremendously. Some years ago, he was in New York, and he gave an interview with The Times, and what he said was this: "In my work, I try to capture the closeness of the everyday and the distance of myth. Because, without the closeness, you can't be moved, and without the distance, you can't be amazed." Isn't that extraordinary?

I've been asked several times over the years to become president, and I've always said no, because I didn't want to give up all the time from my work. The position won't be open for another year, but if they still want me then, I'll do it; I'll speak out as often as I can from that platform.

That's all I've ever dreamed of, Mr. Bones. To make the world a better place. To bring some beauty to the drab humdrum corners of the soul. You can do it with a toaster, you can do it with a poem, you can do it by reaching out your hand to a stranger. It doesn't matter what form it takes. To leave the world a little better than you found it. That's the best a man can ever do.

Every life is inexplicable, I kept telling myself. No matter how many facts are told, no matter how many details are given, the essential thing resists telling. To say that so and so was born here and went there, that he did this and did that, that he married this woman and had these children, that he lived, that he died, that he left behind these books or this battle or that bridge – none of that tells us very much.
