You have handled money every day of your adult life and you have almost certainly never been told what it is.
Volume III11 chapters, each with its whole teaching unit, and 3 extensions: one for the practitioner, one for the corporation, one for the translation between them.
The chapters
Plate III.01The Column of Figures.Money has never been a substance. It is the agreement that these two columns must always match, held by enough people, for long enough, that the agreement can be spent.
Plate III.02The Meter and the Kettle.The meter counts joules. Her hand is checking something the meter has no column for — whether this particular heat, in this particular hour, is the heat she actually needed.
Plate III.03The Stamp, at the End of the Month.A currency is not a thing. It is an agreement with a running cost, and somebody is always paying it. The only question a design settles is who.
You have almost certainly been told that Wörgl worked and that the bankers stopped it, that the Swiss have run a parallel currency since 1934 and it keeps them steady in recessions, and that a town in England printed its own pound and it was wonderful until it wasn't.
Plate III.04The Slate Behind the Bar.Every credit system in history began as this slate. The interesting question is never who is owed. It is what the village does when the slate fills up.
Plate III.05The Long Table.The table is the same width at both ends. It is the light that falls away. A discount rate is a claim about how fast it falls, and almost nobody who uses one has ever said out loud what theirs is made of.
Plate III.06The Trade at the Root Collar.Everything here is trading with everything else and none of it is generous. That is not a disappointment. It is the reason the arrangement has lasted four hundred million years.
Plate III.07The Core on the Open Page.One of these two objects is audited and one of them is true, and the work of this chapter is to stop that being two different sentences.
Plate III.08The Third Round.One of those notes came in this morning from the flour merchant's daughter, went out at noon to the greengrocer, and will be back on this street before Thursday. Nobody has ever measured that at the level of a country. It is measured here every evening, by hand, in a book.
Plate III.09The Counter at Closing.Every payment you have ever received arrived through somebody's pipe, and somebody set the price of the pipe. The question is only whether you have ever seen the number.
Plate III.11The Standpipe at Six.She pays four times per litre what the household with the meter pays. There is no tariff on this water. That is precisely why it costs her so much.
This is the last chapter of a volume that has spent ten chapters taking money seriously — what it is made of, what it denominates, how it circulates, how it settles, how it is held in reserve.
Three chapters that make the volume usable by practitioners of Luminous Economics and by people inside corporations alike — because they are not different economies, only different vocabularies.
Plate III.E1The Ledger Between Two Trades.The cash box holds what the day settled. The exercise book holds what the day cleared, which is the larger number and the one nobody taught her to write down.
Plate III.E2The Second Page.The decision was taken on page one. The money is on page nine, in a column that has been the same for eleven years because nobody has ever had a reason to open it.
Plate III.E3The Two Ledgers, One Object.Neither ledger is a translation of the other. They are two readings of one object, taken from opposite ends, and the whole craft is knowing which readings have to agree and which have no counterpart at all.
