“Calling an interest in Poussin nostalgic or elitist is like calling the interest one has, say, in the person one cares for most deeply ‘hetero- (or homo-) sexist,’ or ‘exclusive’ or ‘proprietorial.’ Yes, that may be right: those may be roughly the parameters, and regrettable; but the interest itself may still be more complete and human—still carry more of human possibility and compassion—than interests uncontaminated by any such affect or compulsion.”
