4. A child's world is a map. It learns to live in the world by mapping it.Its map of the world is a means of being. A child could not think or movewithout its map of the world. The map must contain and describe boththe known and the unknown places. Nothing may be unmapped.Anything unmapped would belike a hole in nothingness. A child's mindresembles a ruler, if part of the ruler moves the whole moves.
