Citizens of a modern society need [...] more than that ordinary "common sense" which was defined by Stuart Chase as that which tells you that the world is flat. They need to be systematically aware of the powers and limitations of symbols, especially words, if they are to guard against being driven into complete bewilderment by the complexity of their semantic environment. The first of the principles governing symbols is this: The symbol is NOT the thing symbolized; the word is NOT the thing; the map is NOT the territory it stands for.
