An image of a thing is not the thing. Salvador Dali liked to point this out. Men have an image of themselves—a hive of memories, hopes, fears, regrets, opinions, preferences. There’s no problem with this until we mistake the hive for the honey.
In the cinema, an audience takes for real the images on the screen. Back on the street, same phenomenon—people feeling this way or that, taking for real the thoughts in their heads.
