Iain Banks said this quote

Oh, no, Cameron; I believe we're born free of sin and free of guilt. It's just that we all catch it, eventually. There are no clean rooms for morality, Cameron, no boys in bubbles kept in a guilt-free sterile zone. There are monasteries and nunneries, and people become recluses, but even that's just an elegant way of giving up. Washing one's hand didn't work two thousand years ago, and it doesn't work today. Involvement, Cameron, connection.
