'Beauty is not just what we agree to call it, nor does it go away if we ignore it. We can't remake our values at will. There may of course be shifts in art theory, but that is distinct from beauty itself, and we cannot rid ourselves of the value of beauty by a decision in theory. In this, beauty is like other transcendental ideals, such as goodness. Societies may dispute what is to be considered good, but they cannot do away with the concept. What is more the concept is remarkably stable over time. Exactly what is to be considered good may shift around the edges, but the core remains unchanged. Similarly, exactly what is to be called beautiful may vary a little over time, but the core concepts of beauty remain, which is why we have no difficulty in appreciating the beauty of mediaeval or ancient art despite the passage of centuries. Art theory can pronounce the death of beauty, but in doing so it revives memories of King Canute.'
