Since the government did not feel it appropriate to pay for the upkeep of improvidents, prisoners were expected to furnish the full cost of their own imprisonment. If they couldn’t, they simply starved to death.

For thousands of years, the struggle between rich and poor has largely taken the form of conflicts between creditors and debtors—of arguments about the rights and wrongs of interest payments, debt peonage, amnesty, repossession, restitution, the sequestering of sheep, the seizing of vineyards, and the selling of debtors’ children into slavery. By the same token, for the last five thousand years, with remarkable regularity, popular insurrections have begun the same way: with the ritual destruction of the debt records—tablets, papyri, ledgers, whatever form they might have taken in any particular time and place. (After that, rebels usually go after the records of landholding and tax assessments.) As the great classicist Moses Finley often liked to say, in the ancient world, all revolutionary movements had a single program: “Cancel the debts and redistribute the land.”

Since the dead usurer’s friends were very insistent, the priest yielded to their pressure and said, “Let us put his body on a  donkey and see God’s will, and what He will do with the body. Wherever the donkey takes it, be it a church, a cemetery, or elsewhere, there will I bury it.” The body was placed upon the donkey which without deviating either to right or left, took it straight out of town to the place where thieves are hanged from the gibbet, and with a hearty buck, sent the cadaver flying onto the dung beneath the gallows.

the very name, “usurer,” evokes images of loan sharks, blood money, pounds of flesh, the selling of souls, and behind them all, the Devil, often represented as himself a kind of usurer, an evil accountant with the books and ledgers, or alternately, as the figure looming jut behind the usurer, biding his time until he can repossess the soul of a villain who, by his very occupation, has clearly made a compact with Hell.

What, precisely, does it mean to say that our sense of morality and justice is reduced to the language of a business deal? What does it mean when we reduce moral obligations to debts? What changes when the one turns into the other? And how do we speak about them when our language has been so shaped by the market? On one level the difference between an obligation and a debt is simple and obvious. A debt is the obligation to pay a certain sum of money. As a result, a debt, unlike any other form of obligation, can be precisely quantified. This allows debts to become simple, cold, and impersonal—which, in turn, allows them to be transferable. If one owes a favor, or one’s life, to another human being, it is owed to that person specifically. But if one owes forty thousand dollars at 12-percent interest, it doesn’t really matter who the creditor is; neither does either of the two parties have to think much about what the other party needs, wants, is capable of doing—as they certainly would if what was owed was a favor, or respect, or gratitude. One does not need to calculate the human effects; one need only calculate principal, balances, penalties, and rates of interest. If you end up having to abandon your home and wander in other provinces, if your daughter ends up in a mining camp working as a prostitute, well, that’s unfortunate, but incidental to the creditor. Money is money, and a deal’s a deal.

For every subtle and complicated question, there is a perfectly simple and straightforward answer, which is wrong.

“Imagine,” write Parkin and King (Economics, 1995), “you have roosters, but you want roses.”

Aristotle used the term métadosis, which in his day normally meant “sharing” or “sharing out.” Since Smith, this has usually been translated “barter,” but as Karl Polanyi (1957a:93) has long since emphasized, this is probably inaccurate, unless Aristotle was introducing an entirely new meaning for the term. Theorists of the origin of Greek money from Laum (1924) to Seaford (2004) have emphasized that customs of apportioning goods (e.g., war booty, sacrificial meat), probably did play a key role in the development of Greek currency.

The definitive anthropological work on barter, by Caroline Humphrey, of Cambridge, could not be more definitive in its conclusions: “No example of a barter economy, pure and simple, has ever been described, let alone the emergence from it of money; all available ethnography suggests that there never has been such a thing.”

Anne Chapman (1980) goes if anything further, noting that if pure barter is to be defined as concerned only with swapping objects, and not with rearranging relations between people, it’s not clear that it has ever existed.

What all such cases of trade through barter have in common is that they are meetings with strangers who will, likely as not, never meet again, and with whom one certainly will not enter into any ongoing relations. This is why a direct one-on-one exchange is appropriate: each side makes their trade and walks away. It’s all made possible by laying down an initial mantle of sociability in the form of shared pleasures, music, and dance—the usual base of conviviality on which trade must always be built. Then comes the actual trading, where both sides make a great display of the latent hostility that necessarily exists in any exchange of material goods between strangers—where neither party has no particular reason not to take advantage of the other—by playful mock aggression, through in the Nambikwara case, where the mantle of sociability is extremely thin, mock aggression is in constant danger of slipping over into the real thing. The Gunwinggu, with their more relaxed attitude toward sexuality, have quite ingeniously managed to make the shared pleasures and aggression into exactly the same thing.

Recall here the language of the economics textbooks: “Imagine a society without money.” “Imagine a barter economy.” One thing these examples make abundantly clear is just how limited the imaginative powers of most economists turn out to be.

Economics assumes a division between different spheres of human behavior that, among people like the Gunwinngu and the Nambikwara, simply does not exist. These divisions in turn are made possible by very specific institutional arrangements—the existence of lawyers, prisons, and police—to ensure that even people who don’t like each other very much, who have no interest in developing any kind of ongoing relationship, but are simply interested in getting their hands on as much of the others’ possessions as possible, will nonetheless refrain from the most obvious expedient (theft). This in turn allows us to assume that life is neatly divided between the marketplace, where we do our shopping, and the “sphere of consumption,” where we concern ourselves with music, feasts, and seduction. In other words, the vision of the world that forms the basis of the economics textbooks, which Adam Smith played so large a part in promulgating, has by now become so much a part of our common sense that we find it hard to imagine any other possible arrangement.
