Consider the words of the novelist Philip K. Dick:

What a tragic world this is. Those down here are prisoners, and the ultimate tragedy is that they don’t know it, they think they are free because they never have been free, and do not understand what it means. This is a prison and few men have guessed. But I know, he said to himself. Because that is why I am here. To burn the walls, to tear down the metal gates, to break each chain.
