What is the relationship between mind and body?
Maybe the mind is like a video game controller, moving the body around the world, taking it on joy rides. Or maybe the body manipulates the mind with hunger, sleepiness and anxiety, something like a river steering a canoe. Is the mind like electromagnetic waves, flickering in and out of our light-bulb bodies? Or is the mind a car on the road? A ghost in the machine?
Maybe no metaphor will ever quite fit because there is no distinction between mind and body: There is just experience, or some kind of physical process, a gestalt.
