The map-maker and map-user are doing two different things. For the map-maker, the metaphrand is the blank piece of paper on which he operates with the metaphier of the land he knows and has surveyed. But for the map-user, it is just the other way around. The land is unknown; it is the land that is the metaphrand, while the metaphier is the map which he is using, by which he understands the land. And so with consciousness. Consciousness is the metaphrand when it is being generated by the paraphrands of our verbal expressions. But the functioning of consciousness is, as it were, the return journey. Consciousness becomes the metaphier full of our past experience, constantly and selectively operating on such unknowns as future actions, decisions, and partly remembered pasts, on what we are and yet may be. And it is by the generated structure of consciousness that we then understand the world.
