[Flaubert] didn’t just hate the railway as such; he hated the way it flattered people with the illusion of progress. What was the point of scientific advance without moral advance? The railway would merely permit more people to move about, meet and be stupid together.

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.

The better you know someone, the less well you often see them (and the less well they can therefore be transferred into fiction). They may be so close as to be out of focus, and there is no operating novelist to dispel the blur.

The imagination doesn't crop annually like a reliable fruit tree. The writer has to gather whatever's there: sometimes too much, sometimes too little, sometimes nothing at all.

Early in life, the world divides crudely into those who have had sex and those who haven't. Later, into those who have known love, and those who haven't.

These divisions are absolute; they are tropics we cross.
