"According to John Pfeiffer, author of The Human Brain, “There is an entire universe packed inside your skull, a compact model of your surroundings based on all the experiences you have accumulated during the course of a lifetime. Of necessity such a model is limited by the range of one’s perceptions and the nature of one’s experiences. Thus, the world about which I write, the world to which I hold up my distorting mirror, is not the real world in any ultimate sense. It is only my limited, personal image of the real world."
