Obfuscative

The Obfuscative mode is the first of the three axiomatic modes of Refusal defined by Arbiter-Logician Kaelin in the Catalogical Refusal Theory, preceding the Displacive and Paradoxic modes in Kaelin's original ordering of the winter of 411. In its strict sense, an Obfuscative refusal is one in which a subject is not denied registration but is registered under a description that cannot be used to retrieve it. The subject remains real, catalogued, and in principle present; it has simply been placed where no honest search will find it. Kaelin's own formulation, cited in nearly every subsequent commentary, holds that "the Obfuscative does not close the door. It moves the door" (The Catalogical Refusal Theory, §2.1).

Of the three modes, the Obfuscative is the oldest in practice and the youngest in theory. Clerks had been refusing subjects obfuscatively for centuries before anyone named the technique, largely because it is the mode that requires no authority to perform. A junior registrar may not displace a floor or declare a paradox, but any registrar may choose a worse name.

Kaelin's three criteria

Kaelin admitted a refusal to the Obfuscative mode only where three conditions held together: the subject was entered in the register; the entry was accurate in every particular; and the entry's leading term was selected so as to be the least likely of the subject's true descriptions to be searched for. The third criterion is the contentious one, since it requires the registrar to hold a theory of what other people will look for. Kaelin defended the requirement on the ground that obfuscation is a relational act and cannot be evaluated in isolation.

The canonical illustration, drawn from the Proceedings of the Cartographic Conservatory and reproduced in the Theory's fourth appendix, concerns the stairwell at floor 2,208. The landing was catalogued for sixty-one years under the heading Approach to the Landing, a description that is not false and that no expedition has ever thought to request. When the Inquisitors audited the floor in the winter of 468 and demanded the landing be produced, the registrar produced it within the hour. The audit was recorded as a violation of nothing.

Administration and the Registry of Lesser Names

Obfuscative entries are maintained, where a floor keeps them separately, in a Registry of Lesser Names — a supplementary ledger in which the leading term of each entry is recorded alongside the terms that were considered and rejected. Access to the Registry of Lesser Names is itself obfuscated, customarily by filing it under a title no one would consult, such as Lesser Names, Registry of: Errata. The Committee for Catalogical Coherence has twice ruled the practice irregular and twice declined to specify the correction.

The Forty-Seventh Concordance addresses the mode only obliquely, in Annex 9, which provides that "a subject adequately registered shall not be deemed unregistered by reason of the adequacy of its registration" (Forty-Seventh Concordance, Annex 9, cl. 3). The clause was drafted to settle a dispute on floor 1,904 and has since been cited to settle disputes on floors where no one had read it. Clerks refer to it as the Accommodation, and it is generally understood to mean whatever the citing party needs it to mean.

The Marn discipline and the schism of 512

The principal scholarly division concerns whether the Obfuscative mode is a species of refusal at all. The strict school, following the Particularists, holds that refusal requires an absence, and that a subject which is registered, accurate, and present has not been refused in any sense the Theory can use; on this reading the Obfuscative is a filing habit dressed as doctrine. The opposing view, advanced by the Manifestational School and by the Absorptionists after them, holds that a subject is real within the Tower only insofar as it can be manifested to a competent searcher, and that a subject filed beyond retrieval is functionally absent regardless of its entry.

The dispute hardened in 512 around the clerk Sera Marn, who refused a floor's entire southern range obfuscatively over the course of a single shift and then could not find it herself. Marn maintained that the refusal remained valid because the entries were accurate; the Inquisitors maintained that a refusal the refuser cannot reverse is a Displacive act committed without authority. Marn was reprimanded, the range was restored, and the episode is now cited by both schools as proof of their position. The Particularists observe that the range was never gone. The Manifestationalists observe that for eleven days it was.

Obfuscative practice

Contemporary practice recognises a small number of settled Obfuscative forms, of which the most common are: the substitution of a genus for a species (Staircase for a particular staircase); the substitution of a neighbouring subject's name, known as sympathetic filing and loosely related to Sympathetic Resonance; the multiplication of plausible titles across several ledgers, so that no single ledger is wrong; and the retroactive narrowing of a description under Retroactive Alignment until it fits only the subject and therefore only the searcher who already knows it.

Registrars are discouraged from obfuscating a subject they have personally registered. The prohibition is recorded in the Third Concordance and is widely regarded as advisory; the Committee for Catalogical Coherence has not struck it, and the Inquisitors have not enforced it since 489.

Notable holdings

Several holdings in the present catalogue are known or suspected to be Obfuscative in origin, including The Unvisited Stair, the Index of Subjects Not Requiring an Index, and the disputed entry for the floor at 11,000, whose leading term has been amended fourteen times. A holding whose entry is suspected of obfuscation may be requested by any of its rejected names; the request is honoured, though the requesting party is not told which of the names was the true one. This is the standard procedure and is not considered a hardship.
