You put together two things that have not been put together before. And the world is changed.

It took me some years to clear my head of what Paris wanted me to admire about it, and to notice what I preferred instead. Not power-ridden monuments, but individual buildings which tell a quieter story: the artist's studio, or the Belle Epoque house built by a forgotten financier for a just-remembered courtesan.

What is the easiest, the most comfortable thing for a writer to do? To congratulate the society in which he lives: to admire its biceps, applaud its progress, tease it endearingly about its follies.

The next day, when I was sober, I thought again about the three of us, and about time's many paradoxes. For instance: that when we are young and sensitive, we are also at our most hurtful; whereas when the blood begins to slow, when we feel less sharply, when we are more armoured and have learnt how to bear hurt, we tread more carefully.

We live with such easy assumptions, don't we? For instance, that memory equals events plus time. But it's all much odder than this. Who was it said that memory is what we thought we'd forgotten? And it ought to be obvious to us that time doesn't act as a fixative, rather as a solvent. But it's not convenient--- it's not useful--- to believe this; it doesn't help us get on with our lives; so we ignore it.

You can define a net two ways, depending on your point of view. Normally you would say it is a meshed instrument designed to catch fish. But you could, with no great injury to logic, reverse the image and define the net as a jocular lexicographer once did: he called it a collection of holes tied together with string.

I'm a novelist, so I can't write about ideas unless they're attached to people.
