Gallery of Unspoken Premises

The Gallery of Unspoken Premises is a hanging exhibition hall on Floor 3,417, occupying the twelve-metre span between the western face of the Aviary of Unspoken Premises and the landing known as the Vestibule of Unanswered Premises. It is not an aviary, though it shares the Aviary's catalogue series, and it is not a vestibule, though every visitor reaches it through one. By the definition recorded in Context Notation 3,417-A, the Gallery is "a place where premises are displayed in the state in which they were held, whether or not they were ever spoken."

The Gallery holds no objects. It holds positions — the assumptions on which statements pending elsewhere in the Tower are founded — mounted on iron armatures and lit obliquely from the western clerestory. It has been open continuously since its founding and has never once been closed for maintenance, a fact the Office of the Keeper of Unspoken Components notes with visible irritation in its annual returns.

Founding and the Spoke Dispute

The Gallery was constituted by Concordance 210, Clause 3, following an audit of the Aviary's western span in the winter of the year counted as 3,416. The audit found more than four thousand premises in circulation among the Aviary's researchers that had never been entered in any catalogue, on the grounds that nobody had thought to say them aloud. Concordance 210 required that such premises be given wall space "lest they be mistaken for facts." The Gallery opened nine months later with three hundred and six exhibits and a staff of two.

The first exhibit remains in situ at the head of the entry stair and is identified only by its accession number, G-001. Its armature is visibly bowed. Attendants are instructed not to discuss what it holds, and they do not.

Arrangement of the hang

The Gallery is hung in a single continuous course, west to east, and the course is read as a single argument rather than as a collection. Successive exhibits are meant to be followed as premises in an unbroken chain; a visitor who begins at the entry stair and walks the full twelve metres will arrive at the eastern door in possession of a complete syllogism, which the door will not open to admit. The syllogism is not written down anywhere. Visitors are advised to bring their own pencil.

Three sections are conventionally distinguished:

• The Long Course — the principal hang, comprising some eleven hundred exhibits in sequence, restrung each year in a marginally different order by the Scriptorium of Revised Premises.
• The Annex of Deferred Cases — premises whose truth value is pending before another floor and which may not be displayed in sequence until the matter is settled.
• The Recess — a narrow side gallery containing premises withdrawn by their own holders, kept on view but turned to the wall.

The annual restrung hang is the subject of an ongoing grievance. Curator Ilvahen Marr, appointed to the Long Course in 3,402, maintains that a course read as a sequence cannot be reordered annually without producing a different syllogism each year, and that the Gallery has consequently asserted forty-one distinct conclusions in forty-one years. The Scriptorium's position, recorded in its reply of 3,419, is that the course has only ever asserted one conclusion and that "the variation is in the visitors" (Scriptorium of Revised Premises, Memorandum 88). Curator Marr's rebuttal is still in draft. She has been in draft for nine years.

Harmonics and the clause in dispute

Because the exhibits are armatures under tension, the Gallery produces a continuous low tone, measured at 41 hertz at the centre of the Long Course and falling to 33 at the eastern door. This tone is classified under the Seventh Concordance as a form of procedural auditory residue, and the Gallery therefore falls within the ambit of Echoes of Unspoken Arguments. Attendants carry ear-plugs and are rotated every four hours. The tone is audible in the Vestibule of Unanswered Premises on still days and has been blamed, without evidence, for the peculiar patience of the clerks stationed there.

The classification is contested. Seventh Concordance Clauses 44–92 govern echoes arising from premises "formed but never vocalized," whereas the Gallery's exhibits were never vocalized because they were never formed in language at all. The Gallery's own reading, advanced by the Keeper in 3,388, is that the tone arises from the armatures and not from the premises, and that the Seventh Concordance accordingly has no application.

"The tone is in the iron. The iron is catalogued under the Vault. The Vault does not sing."

— Office of the Keeper of Unspoken Components, Ruling of 3,388, §7

The Bureau of Unspoken Context has declined to resolve the question, noting in Notation 3,417-C that a determination either way would require the Gallery to be reclassified, and that reclassification would require the Long Course to be measured again. The measuring was last attempted in 3,401 and took eleven weeks.

Relationship to the Aviary

The Gallery is administered jointly by the Aviary and by the Bureau of Unspoken Context, under Bureau Directive 440.12, Annex 7, which assigns cataloguing of the Gallery's holdings to the Aviary but reserves to the Bureau any question of whether an exhibited premise has been spoken. In practice this means the Aviary may number a premise but may not say what it is. The distinction has been eroded by custom: attendants on the Long Course routinely announce an exhibit's number aloud as they pass it, which the Bureau has ruled does not constitute speaking the premise, "the number being a handle and not a claim" (Notation 2,904-F).

The Gallery is formally designated a sub-aperture of the Aviary of Indelible Ideas, an arrangement inherited from the Aviary of Unspoken Premises and never separately ratified. Requests for ratification were made in 3,355, 3,372, and 3,414. All three are in the Annex of Deferred Cases.

Access and visiting conditions

The Gallery admits visitors between the second and ninth hours. Premises may be viewed but not leaned upon, and the iron armatures are not to be steadied by hand; several are load-bearing and one is load-bearing for the floor above. Visitors arriving from the Courtyard of Errant Premises should note that the Courtyard's eastern arch does not connect to the Gallery, despite the sign, and that the sign is itself an exhibit, on loan since 3,409 and overdue.

Premises of the visitor's own may be deposited at the entry stair for cataloguing. Deposits are held for one year and then, if unclaimed, turned to the wall in the Recess with the others. The Gallery does not return them, and inquiries should be directed to the Index of Unspoken Conclusions, which maintains the register.
