My characters, I find them as I'm writing. It's quite incredible how fully realized they are in my mind, how many details I know about each of them.

The joke is the purest, most essential form of storytelling. Every word has to count.

I see myself as anybody, as everybody; I'm not just telling the story of my life to give the reader a picture of who I am.

Most of my friends' fathers had been in the war - either as soldiers or in some other capacity in the military. Whereas my father had not fought. He was older and he was in a business that was considered essential to the wartime effort - the wire business - and, of course, I was so young I didn't understand any of this.

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.

We are left with nothing but death, the irreducible fact of our own mortality. Death after a long illness we can accept with resignation. Even accidental death we can ascribe to fate. But for a man to die of no apparent cause, for a man to die simply because he is a man, brings us so close to the invisible boundary between life and death that we no longer know which side we are on. Life becomes death, and it is as if this death has owned this life all along. Death without warning. Which is to say: life stops. And it can stop at any moment.

The childhood scenes [ in The Tree of Life] are tremendous. My favorite moment is when the mother levitate - for three seconds. Of course, this is how a child thinks of his mother.
