Gulf of Unfinished Syllogisms

Definition and Extent

The Gulf of Unfinished Syllogisms is a sunken reading-room and flood-basin occupying the eastern third of Floor 909, entered from the western colonnade of the Hall of Unresolved Syllogisms through a doorway listed in the floor inventory only as Aperture beta. It is not, despite the name, a body of water in the ordinary sense. The Gulf is filled to a depth of between four and eleven metres with a slow, salt-bearing fluid classified by the Office of Acquisitions & Stasis as suspended argument: a brine in which the discarded connective tissue of Unclosed Syllogisms — suppressed premises, orphaned therefore-clauses, marginal objections never answered — remains in colloidal suspension and does not settle.

The Gulf has no tide and one current, called the Drift, which moves west to east at approximately two centimetres per hour and has never been observed to reverse. Sound carries across it poorly. The Librarians who work the basin's edge are issued wading poles graduated in half-metres; the poles are for measuring depth, and regulation forbids their use for any other purpose.

The Reading-Basin and Its Apparatus

Traversal is by raised walkways set at a fixed height of one metre above the mean surface, supported on stone pilings sunk before the basin was flooded. Where a walkway must pass over deeper fluid, the pilings are continued upward into narrow towers from which readers may be lowered in the suspended cradle, or lectern-chair, to examine submerged argument at close range. The cradles seat one. A second person may not be lowered on the same cable, a rule introduced after the winter of the double signature (see below) and reaffirmed under Annex 7 of the Fourth Concordance, which governs all procedure within the Hall of Unresolved Syllogisms.

Argument retrieved from the Gulf does not dry. It is catalogued wet, on waxed cards, and any attempt to reduce it to a dry summary requires the countersignature of two Librarians — one of whom must have stood a full shift at Aperture beta within the preceding year. The wet-card catalogues are kept in the eastern annexe and may not be removed from Floor 909. A borrowing ledger exists; nothing has been borrowed from it since 14 Frost, and the blank line for that date remains blank in the archive's own copy.

Jurisdictional Dispute

Administration of the Gulf is contested. The Chamber of Unfinished Symphonies asserts an interest on the grounds that the Drift's slow eastward movement constitutes a sustained unresolved tone, and has twice attempted to station a tuning clerk at the basin's edge. The Office of Acquisitions & Stasis rejects the claim, quoting its own instrument of 6 Ember: "Detecting Unclosed Syllogisms is a duty of this Office wherever they lie, and lying in brine does not remove them from our detection." The Chamber replies, in a memorandum signed by its Under-Keeper of Sustained Tones, that "detection is not the same as custody, and custody is not the same as ear." Neither office has conceded, and for nine years both have paid the wages of the same basin-keeper, a clerk named Orra Vesk, who accepts both salaries and keeps two sets of books.

Vesk's grievance is a matter of record in her own hand. In a petition submitted to the Panel of Logical Equilibrium she complained that her two employers had each instructed her to record the other's inspections as "irregularities," with the result that every shift produced two irregularities and none could be acted upon. The Panel declined to hear the petition, noting that Vesk had framed her complaint as a syllogism and the syllogism was unclosed. The decision is often cited as the Tower's clearest small joke; it was not intended as one, and Vesk did not find it amusing.

Doctrinal Question: Is the Gulf a Floor?

The more serious dispute concerns what the Gulf is. The Third Concordance, Annex 2, lists the Gulf as a "structural feature" of Floor 909, on the reasoning that no separate floor number has been assigned to it. The Fourth Concordance takes the contrary position in the same Annex 7 that governs the Hall: because the basin was dug after the floor was numbered, it "stands to the floor as a held breath stands to the body," i.e., as a distinct place. Under this reading the Gulf ought to carry its own designation, and four successive floor-numbering boards have declined to issue one.

The practical consequences are small but stubborn. If the Gulf is part of Floor 909, its depths fall under the Hall's jurisdiction and the Contest of Contradiction may be held partly over water, as it was in the seventh and twelfth contests. If it is a separate place, the Contest of Contradiction must remain on dry stone, and the basinside awnings erected for the twelfth contest were unlawful, a matter never resolved and never quite dropped.

"Where a place is both deep and named, the name is the floor and the deep is the place."

Winter of the Double Signature

In the hard winter of that year — the year is recorded inconsistently as 11 and 12 Frost, and the archive keeps both — a reader named Delph Orrin was lowered in a lectern-chair together with a second reader, a breach of the one-person rule, on the theory that two simultaneous readings would close an argument faster. The cable fouled the eastern piling. Neither reader could signal. By the time the cradle was recovered, both had written full and mutually exclusive conclusions on the same submerged premise, and each had signed the other's card. The cards could not be separated without destroying both, and the Gulf's brine made a clean separation impossible; the cards remain, conjoined, under a sealed case in the eastern annexe. Both signatures are legible. Neither reader's conclusion has ever been certified.

Since that winter, no cable has been lowered without a paper strip bound to the wrist of the occupant, renewed each shift, reading in full: One occupant. The strip is not a signature. The strips are printed at Floor 909's own press and are not to be reused.

Inventory of the East Basin

The last complete sounding, taken over four days and entered in the wet-card catalogue, records the following in the deepest reach:

• Thirty-one orphaned therefore-clauses, coherent when raised singly, silent in combination.
• One full argument, undamaged, which no Librarian has been able to read without supplying a premise that is not on the card.
• The conjoined cards of Delph Orrin and the second reader, unrecoverable from above.
• The standard sounding float, returned each day to the same mark without having been moved.

The float's behaviour is noted in the catalogue without comment and has been referred to the Curatorium of Unfinished Likenesses for drawings, which have not yet been made.
