Realized Absence

Realized Absence is the condition under which a thing that has never existed, or has ceased to exist with sufficient thoroughness, is entered into the Tower's records as present. It differs from ordinary absence in being administrable. An unrecorded absence is merely empty floor; a realized absence is empty floor with a file, a seal, and at least two witnesses willing to testify that the floor is as they found it. The distinction was drawn formally in Ordinance of Calibrated Absence, Clause 9, and has been litigated at intervals ever since.

The phrase first appears in a memorandum of the Realized Absence Guild dated 11 Fogmonth, in a hand now attributed to Silas the Unseen, concerning three chairs removed from a reading room on floor 1,140. The Guild has never retracted the memorandum, though its procedural manuals cite it without comment; the chairs were returned before the file closed.

Doctrine

Realized Absence is produced, not found. The Realized Absence Guild holds that absence becomes realized only when it has been operationalized — that is, observed under calibration, attested by a Witness of Absence, and sealed in a Certificate of Verified Absence. The Ontological Parity of Absence supplies the underlying claim: that a calibrated absence and a present object occupy the same register for the purposes of cataloguing, and may be shelved adjacently.

In practice the register is easier to assert than to maintain. The standard instruments of realization are the Absence Anchors, which fix an absence to a floor and prevent it drifting into a neighbouring jurisdiction, and the Receivers of Absence, which hold the condition long enough for it to be measured. Where an anchor has been improperly seated, the recorded absence has been known to migrate to the floor above, generally at night, and to be reported the following morning as an unexpected quietness in the stacks.

"No absence shall be realized in a corridor, a lift shaft, or any stair between floors, these being transit spaces in which the condition cannot be brought to rest."

— Ordinance of Calibrated Absence, Schedule 3, Clause 2

The appropriate readings are governed by the Realized Absence Guild, and the manufacture of reference materials by the same body, most notably Absence L-Λ-12, the calibration standard against which a candidate absence is compared. It is a small brass block with nothing in it, and it is checked every seventh year.

The Winter Filing Dispute

In the winter of the year the archive records as 11,842, the Realized Absence Guild and the Guild of Theoretical Mechanics (GTM) filed overlapping claims on the same space: a disused store on floor 1,309, held by the Guild to be a realized absence of a staircase, and by the Mechanics to be an unrealized staircase. Each office produced documentation against the other, and the two files remain bound together under a single spine in the annex.

The matter was settled not on principle but by the intervention of the Guild of Groundskeepers, whose Absence Branch observed that the store had, throughout the dispute, been used for brooms. Neither claimant had noticed. The store was reclassified as a held object, the broom remained, and the finding is cited in the Guild's manuals as the cautionary case of the unexamined room. The Groundskeepers' Absence Branch has collaborated with the Realized Absence Guild on all such matters since, on terms never published.

A related and still unresolved dispute concerns the Constructivist Guild, whose historical adversarial relationship with the Realized Absence Guild stems from its position that an absence is realized by being made rather than by being certified. The Constructivists have twice filed to have Clause 9 amended and twice withdrawn the filing before reading.

Measurement and Tolerance

Realized absence is measured in vacuometric units, calibrated so that the interior of a closed and empty drawer of standard size reads as 1.00. The tolerance for a certified realization is not more than 0.04 units variance from the calibration standard. Anything beyond this is classed as Absence Flux and must be re-anchored before certification; an excess has been recorded on floor 2,206 on two occasions, both in spring, and in both cases traced to a door left ajar by the porter.

Vacuometric readings are recorded by the measuring Clerk of Receipts, a post at present occupied by Clerk Ottilie Vanner, who has requested a change of floor for four consecutive years on the grounds that the vacuity on floor 1,461 is extreme. Her request has not been refused. It has, more precisely, not been answered, though it has been stamped.

Realized Absence of Persons

Persons may be realized as absent, but only with the attestation of a Witness of Absence licensed by the Realized Absence Guild. The Guild maintains a register of realized persons who are, by definition, not available to confirm it. The register is corrected annually, and no correction has yet altered an entry.

The condition of a realized person differs from the records held under Absence 417-Λ9 and Absence 001-Λ9 in that those designations attach to specific withheld holdings rather than to an individual's vacancy. The Guild's manuals refer to Silas the Unseen in this capacity and note, without further remark, that he has signed every annual revision.

Criticism

The received criticism is that Realized Absence is a filing convention dressed as a condition. The Contextualists have argued, in a paper read twice at the Annex of Contested Holdings, that an absence realized in the archive and not in the corridor is a property of the file rather than of the place. The Realized Absence Guild's reply, appended to the paper, runs to one line: "The file is in the corridor."

The Guild has not elaborated. The correction has been adopted in some recensions and omitted in others, and both recensions remain in use.
