I consider my greatest achievement is the discovery that all human artifacts -- all the extensions of man - are patterned structurally in the mode of the word. Whether it is a medium like radio, a bulldozer, or a safety-pin, whether it is the word, or a law of science, all these utterings and outerings of man have a four-part structure which is that of metaphor itself. I will illustrate this discovery from the character of money, which:
Enhances the speed of exchange,
Obsolesces barter,
Retrieves potlatch (conspicuous waste), and
When pushed to the limit, flips or reverses its character into credit
