Polian Thesis of Necessary Absolutes

The Polian Thesis of Necessary Absolutes (Compendium P-V/1) is the foundational statement of the Tower's doctrine of internal consistency. It holds that any record whose internal logics are immutable must not be permitted to deviate from them, and that such deviation constitutes a corruption of the record. The Thesis does not assert that its absolutes are true in any external sense; it asserts only that, once posited, they may not be departed from. In the phrasing of its third recension, "an absolute is necessary not because it is correct but because it has been entered."

The Thesis is the parent document of the Polian corpus. The Polian Theorems are derived from it, and the First Polian Corollary from the Theorems; the Polian Gauge is the Instrumental lineage that follows from the same derivation. To cite the Thesis in a dispute is generally to end the dispute, or to relocate it to a question of which recension is in force.

Origin and recensions

The Compendium was assembled on Floor 88-Gamma over a period of eleven years by a working party whose membership is recorded only by initials. Four recensions survive. The first is fragmentary and consists largely of a list of absolutes that the working party declined to explain. The second adds the doctrine of immutability; the third adds the corruption clause; the fourth is a fair copy of the third with two marginal corrections in a later hand, one of which reads simply "no."

Dispute over which recension is authoritative has occupied the Committee of Necessary Splits since its formation. The Committee's standing ruling — that all four recensions are in force simultaneously and that a citation must specify which — has the effect that a sufficiently determined disputant can find support for any position in the Compendium, provided the correct recension is named. The Doctrine of Necessary Precedent was developed largely to manage the resulting case law.

The corruption clause

The corruption clause is the operative paragraph of the Thesis and the source of nearly all litigation under it. It provides that a record which deviates from its own posited absolutes is "corrupt, and to be corrected, or else re-founded entire." The clause does not specify who may declare a corruption, by what procedure, or what happens to a corrected record's prior citations. Third Concordance Annex 4 attempts to supply the procedure but is itself internally inconsistent at clause 4(c), a defect acknowledged in the Annex's own errata and never repaired.

"Where an absolute has been posited, the record shall cleave to it; where the record has not cleaved, the absolute shall be examined; where the absolute has been examined, it shall be found necessary. The circularity is intentional and is not to be raised."

— Third Concordance, Annex 4, clause 4(b)

The final sentence has been raised, repeatedly, most notably by Theoretician Vek in the Marginalia on Polian Negation, where it is observed that a clause forbidding its own objection is not an absolute but a preference with a seal on it. Vek's observation is widely quoted and has never been answered.

Relation to the Inherency Thesis

The Inherency Thesis is frequently read as a companion to the Compendium, and the two are often cited together. The Inherency Thesis develops the concept of the seam as an operational consequence of the Principle of Inherency, and its partisans argue that a record's intrinsic clarity of seam is the proper test of whether it has deviated from its absolutes. The Polian school rejects this on the ground that seam clarity is a property of the record and the Thesis concerns only its logics — a distinction that has never been made to satisfy anyone who was not already satisfied.

The disagreement matters in practice. Under the Polian reading, a corrupt record may be corrected by restoring its logics. Under the Inherency reading, a record with a poor seam cannot be corrected at all, only re-founded. The two schools have divergent estimates of how many floors require re-founding, differing by a factor of roughly nine.

The Haversham objection

The most persistent external objection is that of the Algernon-Haversham Thesis of 1929, which argues that certain phenomena are paravibrational and cannot be reduced to simple wave interference. Haversham's point, as applied to the Compendium, is that some records deviate from their absolutes not by corruption but by a mode of deviation the Thesis has no vocabulary for; such records are neither corrupt nor sound, and the corruption clause passes over them in silence. The Wave-Pattern Thesis was developed in part as a reply, and the exchange between the two positions constitutes the longest running disagreement in the Polian literature.

No resolution has been recorded. A joint reading party was convened on Floor 88-Gamma in the winter of the year the fourth recension was copied, and adjourned after four days without a finding. The room has been kept available since. It is not to be used for storage.

Practical application

In daily cataloguing, the Thesis is applied through the Polian Gauge, which measures an entry's alignment with its proposed location and returns a coefficient. Entries falling below the threshold are held for correction; entries falling below the correction threshold are held for re-founding; entries returning no reading at all are entered as found and flagged, a category the Compendium does not anticipate and the Doctrine of Necessary Fictions was obliged to accommodate after the fact.

The Seal of Necessary Existence is affixed to the fair copy alone. It is affixed on the recto, at the foot, and must not be affixed to a recension. The seal on the first recension was applied in error and has been left in place, since removing it would itself constitute a deviation.
