Above and beyond

"Let's say that the world is in essence neutral – flat, bereft of meaning and significance. It's us, our imaginations, that make it vivid, fill it with colour, feeling, purpose and emotion. Once we understand this we can shape our world in any way we want. In theory." – "Sounds very radical." "On the contrary – it's very commonsensical." (William Boyd, Waiting for Sunrise)
