In a democratic culture people are inclined to believe that it is presumptuous to claim to have better taste than your neighbour. By doing so you are implicitly denying his right to be the thing that he is. You like Bach, she likes U2; you like Leonardo, he likes Mucha; she likes Jane Austen, you like Danielle Steele. Each of you exists in his own enclosed aesthetic world, and so long as neither harms the other, and each says good morning over the fence, there is nothing further to be said.
But things are not so simple, as the democratic argument already implies. […] It is part of our rational nature to strive for a community of judgement, a shared conception of value, since that is what reason and the moral life require. And this desire for a reasoned consensus spills over into the sense of beauty.
– Roger Scruton, Beauty (2009)
