Taxonomy of Qualia Weights

The Taxonomy of Qualia Weights is the formal cataloguing system for the subjective "mass" or "impact" of non-objective phenomena within the Tower. Maintained by the Scriptorium of Minor Weights under the supervision of the Bureau of Implementable Abstraction, it provides a quantitative framework for the otherwise unmeasurable, assigning numeric values to transient impressions, unrealized concepts, and spectral resonances.

Foundational Principles

The Taxonomy operates on three axiomatic principles, as established in Ordinance 4, Annex C (1912):

1. Subjective Quantification: Any mental or perceptual event that lacks a persistent physical correlate can be assigned a provisional weight.
2. Additive Non-Linearity: The aggregate weight of multiple concurrent qualia may exceed or fall short of their simple sum, a property governed by the Metrical Interference Coefficients detailed in Annex D.
3. Contextual Decay: A qualia weight is not fixed; it diminishes according to a standardized half-life schedule unless reinforced by recurrent observation or archival cross-reference.

Weights are logged using Form M-W/44 in the Registry of Minor Impressions. The base unit is the mora (symbol: ), defined as the minimum perceptible weight of "the scent of rain on unvisited stone." All other weights are calibrated against this benchmark.

Structural Hierarchy

The Taxonomy is organized into a multi-tiered hierarchy, distinct from but occasionally intersecting with the Grand Taxonomy. Its primary divisions are:

• Ephemera (E- series): Fleeting sensory impressions (e.g., E-117: "The afterimage of a extinguished candle," 2.3).
• Conceptual Fragments (CF- series): Incomplete ideas or unresolved theorems (e.g., CF-89: "The square root of regret," weight variable).
• Residual Atmospherics (RA- series): Ambient emotional tones clinging to locations or objects (e.g., RA-45: "The quiet optimism of an unsent letter," 15.7).
• Anticipatory Phantoms (AP- series): The vivid weight of events that were expected but did not occur (e.g., AP-12: "The applause for a cancelled performance," 42.0).

A separate appendix catalogues Cross-Referential Resonances, where the simultaneous filing of two qualia under distinct taxonomic branches generates a third, emergent weight, a process central to the Metrica of Minor Manifestations.

Administration and Application

Day-to-day administration falls to the Scriptorium of Minor Weights, located on Annex B of Floor 112. Scriptors are trained to perform qualia assay, a meditative evaluation process standardized by the Central Scriptorium. Disputes over weight assignments are resolved not by recalibration, but by the filing of a Counterweight Annotation, which adds a modifying entry without altering the original record, in accordance with Concordance 89.

The primary practical application of the Taxonomy is in logistics and spatial planning. The aggregated qualia weight of a floor's holdings must be calculated to determine the necessary thickness of Living Stone supports and the required spacing of Aperture Markings to prevent perceptual bleed-through into Adjacent Unrealities. Furthermore, the Catalogue of Ambivalent Tools uses recorded weights as inputs for materialization probability matrices.

Scholarly Disputes

The most persistent controversy concerns the Taxonomy's relationship to the Grand Taxonomy. The Great Re-cataloguing attempted to reconcile the two systems, but fundamental incompatibilities remain. Proponents of the Grand Taxonomy argue that qualia are merely attributes of higher-order unreal objects and should be subsumed as sub-classifications. The Scriptorium of Minor Weights, citing the Tenth Concordance, maintains that qualia possess independent ontological weight and require a separate, parallel indexing system.

A secondary, more technical dispute involves the so-called "Pluralist Anomaly." When a qualia is observed simultaneously by multiple entities (see Pluralist doctrines), its measured weight does not always divide predictably among the observers. Some scholars within the Castes of the Citadel argue this proves qualia weight is a property of the observation event itself, not the phenomenon observed, a stance that challenges the Taxonomy's foundational first principle.

Notable Anomalies

The registry contains several entries that defy standard classification:

Entry -0

The theoretical "zero-weight" qualia, defined as the perception of perfect neutrality. All attempts to file an instance have resulted in the form being left blank, yet physically occupying space in the ledger.

Resonance Cascade E-117/CF-89

The persistent cross-reference between the afterimage of an extinguished candle and the square root of regret periodically generates an autonomous, roaming chill documented on seven separate floors, though it possesses no independent file.

The SFU-R

An entire dissolved sub-department whose collective procedural anxiety was posthumously assigned a collective qualia weight of 10,000. This "bureaucratic ghost" requires its own structural reinforcements in the lower stacks, per an addendum to the Metrica.

The Taxonomy of Qualia Weights remains a work in perpetual amendment, a testament to the Tower's commitment to cataloguing the full spectrum of nonexistence, from the faintest echo to the most resonant void.
