Turning to page 298:
When Aristotle argued that coins are merely social conventions, the term he used was symbolon-from which our own word " symbol " is derived. Symbolon was originally the Greek word for "tally"-an object broken in half to mark a contract or agreement, or marked and broken to record a debt. So our word " symbol" traces back originally to objects broken to record debt contracts of one sort or another.
Which leads to the question of what it means to do a torn and restored trick.
From page 269 on paper money:
Tallies weren't just used for loans, but for any sort of contract which is why early paper contracts also had to be cut in half and one half kept by each party. With paper contracts, there was a definite tendency for the creditor's half to function as an IOU and thus become transferable. By 806 AD, for instance, right around the apogee of Chinese Buddhism, merchants moving tea over long distances from the far south of the country and officials transporting tax payments to the capital, all of them concerned with the dangers of carrying bullion over long distances, began to deposit their money with bankers in the capital and devised a system of promissory notes. They were called "Flying Cash," also divided in half, like tallies, and redeemable for cash in their branches in the provinces.
Does putting the corner back onto a borrowed and torn bill mean the magic (contract) is gone too?
Before the magic goes, does a torn IOU for a quarter also move the quarter when you move both parts somewhere else?
