The Most Dangerous Metaphors

The most dangerous metaphors for us are the ones that cease to be recognizable as metaphors. For many people the analogy between brain and computer has reached that point: the brain isn’t like a computer, they think, it is a computer. (“A computer made of meat,” some say.) When that happens to us, we are in a bad way, because those screens become permanently implanted, and we lose the ability to redirect our attention toward those elements of reality we have ignored.
