Julian Jaynes Quote
Such trade was not, however, a true market. There were no prices under the pressures of supply and demand, no buying and selling, and no money. It was trade in the sense of equivalences established by divine decree. There is a complete lack of reference to business profits or loss in any of the cuneiform tablets that have been so far translated.
