We all possess, in our unconscious minds, a kind of servant who performs certain automatic functions. When I learn to type or drive a car or learn a foreign language, I have to do it painfully and consciously; then, suddenly, my robot takes over and does it automatically; in fact, he does it far more quickly and efficiently than "I" could. The main trouble with this mechanical valet is that he often takes over functions I would prefer to keep for myself -- for example, when I am tired I eat "automatically," and so do not enjoy my food. In fact, this is the reason that so much of our experience seems oddly "unreal"; the robot has taken it over. When I am feeling low, I may live for whole days in a "robotic" state, so that experience flows off me like water off a duck's back. And because I am not receiving any "feedback" of pleasure or interest from my activities, I become duller than ever, and experience becomes progressively less interesting. (This is, of course, the mechanism of depression and nervous breakdown.) And this is also why explorers deliberately seek out hardship and danger -- to cheat the robot and "feel the life in them more intensely."
