‘You’re talking about manipulating feelings and emotions. Would it not be easier to convince people with a rational, simple and straightforward account?’

‘No. It’s impossible to initiate a rational dialogue with someone about beliefs and concepts if he has not acquired them through reason. It doesn’t matter whether we’re looking at God, race, or national pride. That’s why I need something more powerful than a simple rhetorical exposition. I need the strength of art, of stagecraft. We think that we understand a song’s lyrics, buy what makes us believe in them, or not, is the music.‘

– Carlos Ruiz Zafón, from The Angel’s Game
