"It’s a hierarchy, isn’t it? Art is like religion. The bible was orally transmitted by priests because the bible was in Latin and wasn’t in German or English, so people couldn’t read for themselves and so the church retained the power of explanation. ‘I will explain to you what God means’ and then you go away and do it. I think that art sometimes retains that power."
