Lacrima Cogitationis Secundae

Lacrima cogitationis secundae is the designation, per the Third Concordance (Clause 14.7), for an aqueous suspension of cognitohazardous particulate matter, classified as a Class-II Spiritual Residue. It is generated exclusively during processes of active reconsideration and is primarily collected for archival deposition within the Vault of Conditional Authority.

Composition and Generation

Formally defined as a "psychic condensate of dismissed possibilities and abandoned certainties," lacrima cogitationis secundae manifests as a viscous, opalescent fluid. Spectral analysis reveals a matrix of structured water molecules containing suspended particles of solidified doubt, identifiable by their unique, non-repeating crystalline patterns. The generation process is catalysed by a volitional reversal of a concluded thought process, as outlined in the Tenth Concordance (Annex Δ, "Procedures for Cognitive Recursion"). The most common source within the Tower is the review chambers of the Bureau of Implementable Abstraction, where approved abstractions are periodically re-evaluated.

Collection and Containment

Collection is mandated by the Third Concordance (Clause 14.7.3) for any reconsideration event exceeding a Durational Index of 7. Standard procedure involves the use of non-adsorbent ceramic funnels, designated Model LC-4, which channel the condensate via gravity-fed quartz conduits to regional Vaults of Conditional Authority. These vaults function as specialized absorption nodes, where the lacrima is seeped into porous archive-stone. Contrary to some interpretations, the vaults are not storage facilities but permanent sinks; the lacrima is not retrieved, only recorded.

Disputed Properties

A significant scholarly disagreement, frequently cited in petitions to the Librarians, concerns the material's alleged mnemotropic properties. The Archives of the Fifth Cycle posit that exposure to distilled lacrima can induce a state of "productive uncertainty," a claim supported by the experimental logs of Acoustic Engineer Vect. However, the Bureau of Implementable Abstraction's own findings, compiled in the "Treatise on Finality," argue that any perceived effect is a psychosomatic reaction to the containment apparatus, not the substance itself. This dispute remains unresolved, as the Third Concordance mandates collection but is silent on application, while the Tenth Concordance explicitly prohibits its use outside of archival contexts.

Relationship to Other Condensates

Lacrima cogitationis secundae is often compared to, but is chemically distinct from, other psychic exudates catalogued in the Tower. For instance, samples show a 97% spectral congruence with the exudates documented in the Weeping Codex, yet they lack the latter's characteristic trace elements of regret. More notably, its chemical signature is identical to that of Weeping Lacrima, a byproduct condensate from the Weeping Quarry. This has led to the controversial "Single-Source Hypothesis," suggesting both substances originate from the same, as-yet-unlocated cognitive stratum, a theory complicated by the vast geographical and procedural separation between cognitive review chambers and the Quarry's physical excavations.

Regulatory and Archival Status

Its handling is governed by a complex interplay of concordances. While the Third Concordance dictates its collection, its archival taxonomy falls under the purview of the Archives of Extinct Possibilities, which categorizes it as a "liquid potential." All transfer manifests between collection points and the vaults must be copied to the Archives of Satisfied Grievances, a procedural overlap that Clerk-Substrate Lorn famously described as "the bureaucracy of evaporation." Unauthorized possession or distillation is grounds for re-assignment to a lower floor, as per the ruling in the case of ''Provisional Archivist Kelp v. The Spiral Aperture'' (Cycle 89).

Observed Phenomena

Long-term observational records from the Vaults note two peculiar phenomena. First, deposited lacrima exhibits a minuscule but measurable gravitational fluctuation, with a periodicity that matches the Tower's alleged central chronophage cycle. Second, when accidentally exposed to strong narrative coherence fields—such as those emitted by uncatalogued epics in transit—the fluid temporarily organizes its suspended particulates into legible but nonsensical micro-sentences, which dissipate upon removal of the field. These episodes are logged as "Coherence Echoes" but are not considered a property of the lacrima itself, per the current editorial stance of the Bureau of Elevated Archives.
