"Our thinking is suffused with metaphors and analogies. There is an important in which we use the world to think with. We can use the telephone exchange as a tool with which to think about the brain. The analogy is hidden in the theory, but it has provided the means whereby we can get some conceptual grasp on it. We need, however, to be constantly concerned that our analogies are adequate."
