OBJECTIVE. To distinguish the price of a thing from its cost; to learn that the number on the tag is the smallest of the three numbers attached to it; to develop the habit of squinting.

A price is a small inscription. It looks like a number. It is, in fact, a sentence missing several of its clauses. The full sentence reads, approximately: this thing costs this many of these to me, this many of these to the person who made it, and this many of these to the air around us, and someone has decided to print only the first. The first lesson is to feel that the inscription is short on purpose.

Take a tag from any object within reach. Hold it in raking light. Notice that the number is centered, that the units are smaller than the figure, that there is a small printer's mark in the bottom corner. None of this is decoration. The centering announces seriousness. The small units announce confidence. The printer's mark announces lineage.

  thing             tag-price       carry-price       residue-price
  ----------        ----------      -----------       -------------
  a hand-loom       12 W            ~ 4.20 W          ~ 1.80 W
  a printed scarf   1.80 W          ~ 0.55 W          ~ 0.20 W
  a cup of water    free            ~ 0.04 W          ~ 0.02 W
                

The tag-price is what is shown. The carry-price is what was paid by hands you will never see — the cotton-puller, the dyer, the miller, the stocker. The residue-price is what is paid by the room: the well that gave up the water, the field that gave up the indigo, the lung that gave up the breath. To see a price is to see all three.

OBJECTIVE. To dissect a receipt as one would dissect a small animal in a 19th-century classroom — gently, with named parts, with respect.

A receipt has six parts and one ghost. The six parts are the heading, the date, the ledger, the rule, the total, and the signature. The ghost is the part that is missing — the line that does not appear, but should. We will name them in turn.

The heading announces the place. It is usually printed in a face one degree more decorative than the body, because the place wishes to be remembered. The date places the transaction in time, but only loosely; receipts are written in present tense even when read in the past. The ledger is the body — three to seven rows of description, quantity, unit, total — set in tabular figures so the eye can run vertically and find the column.

The rule is the silent line above the total. It is a hairline. It is the closest thing in commerce to a held breath. The total is the conclusion of the small argument the ledger has been making. The signature is the proof that the argument was witnessed.

The ghost line is the cost the seller paid that the buyer was not asked to know. Sometimes it is rent. Sometimes it is grief. Sometimes it is the dyer's hands, the dyer's lungs, the dyer's afternoon. To learn to read receipts is to learn to feel the ghost line as a small cool draft from the bottom of the page.

OBJECTIVE. To list, in twelve mono-set words, the things you have already paid for that did not appear on any receipt.

Goodwill is the wax that closes the seam between transactions. It is unbilled, untaxed, untyped. It is what your grandmother folded into the dumplings without telling you. It is what the apprentice did at six in the morning so the bread would be ready. It is what the second clerk did when the first clerk forgot. The list is short, on purpose.

— what is given without an invoice is rarely given without a cost. —

OBJECTIVE. To locate, in any object, the costs that have been folded into other costs and gently coaxed to lie still.

Hidden costs sleep in three rooms. The first is the floor: the rent the seller pays, the lighting the seller pays, the salt the seller throws to keep the snow off. The second is the foundation: the cost the maker paid that the seller no longer remembers — the kiln that fired the cup, the loom that wove the cloth. The third is the weather: the ground-water, the hours of daylight, the small administrative grace that allows the transaction to occur at all.

The student should learn to ask, of any price: what room is this cost sleeping in? The answer changes the price. Not numerically. Morally. A cup of coffee whose floor-cost is rent in a kind neighborhood is a different cup from one whose floor-cost is rent in a cruel one. The numerals are equal. The cups are not.

  ----------------    ---------        ----------
  floor               rent, lights     the lease ends
  foundation          kiln, loom       the maker dies

OBJECTIVE. To learn the small art of comparing a thing with another thing when neither thing is the same shape as the other.

The market would have you believe that two goods become comparable when their prices are written on the same kind of tag. They do not. They become comparable only when their residues are written on the same kind of tag, and those tags are very seldom printed. To compare a hand-loom and a printed scarf is to compare two animals: one that has lived a hundred years in a single room, and one that has lived three months in seven cities. Their prices may be equal. Their lives are not.

The auditor recommends a small ritual. Set both objects on the table. Speak aloud, for each: what hands; what hours; what weather. Three short sentences. Then look at the prices. The prices will look smaller than they did before, or larger. Either is correct.

— two unequal goods are not made equal by being weighed against each other; they are made articulate. —

OBJECTIVE. To meet the small silver coin that is the patron animal of this site, and to understand why a coin is also a sentence.

Before the obol there were spits — long iron skewers — and the obol's name comes from the Greek obelos, "spit." Six obols made a drachma; six skewers, in older days, made a handful. The coin began as a tally for what the hand could carry. To this day, a price is, at heart, a question about what a hand can carry. The obol is the smallest unit of accountability that a hand can contain.

An obol was paid to the ferryman; it was placed in the mouth of the dead. This is not a metaphor we will press too hard. We mention it only because it makes a point about the limit of price — there is exactly one transaction that a coin will not buy out of, and that is why every other transaction has a coin attached.

OBJECTIVE. To name three invisible goods that are routinely paid for, and to learn the polite Greek for each.

The Greeks had small words for invisible goods. Charis — grace, the favor a person extends. Aidos — modesty, the willingness to lower one's gaze. Pistis — trust, the credit you extend without paperwork. All three are routinely traded, none of them are taxed. They are the silent currencies that make the loud ones possible.

To audit invisible goods, the auditor uses the wax tablet. She writes nothing, then erases what she did not write. She does this until she has accounted for what is owed and what is owing. The wax tablet is the original double-entry; the second entry is what is missing.

• charis — the favor extended without invoice
• aidos — the discretion that costs the keeper
• pistis — the trust that closes the deal

OBJECTIVE. To find the ghost that lives between the dollar and the cent and to give it a polite name.

The decimal point is a small door. To the left of it, money is solid; to the right, it becomes faintly translucent. $ 4.99 is one cent shy of $ 5.00, and the missing cent is not missing. It is a trick of light. The seller has tilted the price toward the lower whole number, knowing that the eye reads from the left. That tilt is small. It is also a polite haunting.

The student should learn to read prices in round dollars first, and only then in cents. $ 4.99 reads as $ 4 for one second; that second is the ghost's window. To close the window, simply round upward in the head. The ghost will leave. The price will become honest.

— every cent shaved from a round dollar leaves a thin gauze of ghost behind. —

OBJECTIVE. To unwrap a discount and find the original number sleeping inside it.

A discount is a price wearing a costume. It announces itself by crossing out an older price and writing a smaller one beside it, as if the smaller one had won an argument. The argument is rarely real. The older price is sometimes a careful invention. The student must learn to read both numerals as candidates and neither as truth.

To audit a discount: ask when was the original price ever paid? If the answer is often, the discount is genuine. If the answer is rarely or never, the discount is a costume. Costumes are not crimes. They are simply costumes. The student wears them home and then puts them on a hanger.

  -----------   ---------   ---------   ------------   ------------
  scarf         $ 80.00     $ 39.99     rarely         costume
  sofa          $ 1,200     $ 899       sometimes      partial

OBJECTIVE. To learn the small Arabic word tara — what is rejected — and to subtract the container from the contents.

The tare is the weight of the empty vessel. Before you can know how much honey you have bought, you must know how much jar you have bought. Tare is the part of the price that pays for the container, the wrapping, the label, the cardboard the label was glued to. Tare is not bad. It is just not honey.

To find the tare, weigh the empty vessel after the contents are gone. Subtract. The remainder is what was, all along, the contents. The tare-method extends to other things: a service is the contents, the company name is the tare; a meal is the contents, the restaurant rent is the tare. Always weigh the empty vessel.

OBJECTIVE. To watch a scale tilt toward an immaterial thing and to learn what it is teaching.

The Impossible Scale is the auditor's favorite instrument. On one pan she places a small object — an apple, a loaf, a key. On the other she places a written word — honesty, time, consent. The scale tilts. It always tilts toward the word. This is not mysticism. It is arithmetic. A word, properly placed, weighs more than its synonym in bread.

The lesson is this: when you cannot decide between two purchases, ask which word would I place on the empty pan? The pan tilts. You have your answer. Put the apple back. Put the word in your pocket.

— a word, well chosen, weighs more than the bread it costs to choose it. —

OBJECTIVE. To draw, by hand, the receipt for the day you have just spent reading this site.

You came here with a willingness to read. That is the contents. The vessel was the screen, the time, the chair, the small electric hum of the room. You leave with twelve numbered habits and an obol in your pocket. The price of this transaction is set in the next paragraph. You may pay it now, or later, or in some weather you do not yet know is coming.

The price is: the next time someone shows you a tag, look at it for one second longer than you used to. That second is what you owe. The site receives it without further invoice. The marble in the margins receives it as ambient applause. The instructor will not know; she has no nose, and nods to everyone equally.

And now: the small ritual of departure. Stand. Stretch. Thank the seven busts and the fourteen marginal fragments. Close the tab gently — not because the marble would mind, but because you have been quiet for some time, and quiet things deserve to be set down quietly.
