Lois Lowry

Early on I came to realize something, and it came from the mail I received from kids. That is, kids at that pivotal age, 12, 13 or 14, they're still deeply affected by what they read, some are changed by what they read, books can change the way they feel about the world in general. I don't think that's true of adults as much.

The historical novelist has to consider what has actually happened, while the SF writer is dealing in possibilities, but they are both in the business of imagining a world unlike our own and yet connected to it.

There are clearly many good politicians who are guided by religious belief, so the mix can work. But there's a line to be drawn. It would be hugely dangerous for a country's laws to be set by the scriptures, and particularly those of the expansionist religions.
