"The crowning intellectual accomplishment of the brain is the real world. Physicists and chemists long ago demonstrated that the real world of our experience is very different from the inanimate universe of physics and chemistry. The sounds and colors we perceive, the apparent objects that integrate them, the space in which those objects are located, the values we attach to them, the intentions we attribute to others -all these fundamental aspects of the real world of our experience are adaptive interpretations of the really real world of physical science."
