I think wars, climate change, all that stuff is going to move people. And so I wanted to say, "What if the migration apocalypse occurs and it isn't an apocalypse at all?" Maybe we will still find ways to be happy and for our children and grandchildren to thrive and the world to move on.

And also I think the rise of other, you could say, destinations for international jihadis mean that Pakistan isn't necessarily the place where people from all over the world who want to engage in these activities gravitate to. They're going now to places like Syria or Yemen Libya, elsewhere.

I really do believe that people surprise you. And one of the powerful things about novels is that they're about characters, and those characters live their lives.

It's in being read that a book becomes a book, and in each of a million different readings a book become one of a million different books . . .

I think we should be prepared, given environmental and political change for large-scale migration. If sea levels rise and 200 million people in Bangladesh and 300 million people in Indonesia need to move, and the entire Chinese seaboard, New York City - that's going to be huge.

I actually feel that personal matters, like religion and spirituality, are things that I really discuss only with intimates. I think it's, in a way, like sexuality, something where it touches upon something very private.

Yes, Manila had its slums; one saw them on the drive from the airport: vast districts of men in dirty white undershirts lounging idly in front of auto-repair shops - like a poorer version of the 1950s America depicted in such films as Grease.
