Extinct Emotions

Extinct Emotions are affective states for which there is no longer a living capacity within the Tower’s population, rendering them a subject of purely archival and theoretical study. The primary collection is housed on Floor -Ξ (Negative Xi), with sub-deposits noted on Floors  (Seven) and Ω-Δ (Omega-Delta) per the Annex on Anachronistic Affect. As with all holdings, their reality is not in question within the Tower’s jurisdiction; the scholarly debate concerns their original phenomenology and the mechanisms of their extinction.

Major Holdings and Classification

The Department of Ephemeral Psychology maintains the official taxonomy, last revised under Ordinance 747-B. Emotions are categorized by their proposed somatic markers and contextual triggers, as recovered from fragmentary personal journals, discontinued ritual scripts, and annotated margins in culinary texts. Notable specimens include:

• Kairologos: A profound, calm sorrow triggered by the observation of perfectly aligned shadows at equinox. Believed to have been extinguished following the recalibration of the Central Chronophage in Era 12.
• Vellichor’s Antipode: Not the wistfulness of old bookshops (which persists as a common sentiment), but its opposite: a sharp, joyful contempt for the new, specifically for unvarnished wood and uninked parchment. Last empirically recorded during the Paper Shortage of the Lower Stacks.
• Spiral Nostalgia: The longing for a future event that one knows, rationally, will be unpleasant. Documentation is primarily found in pre-Concordance expedition logs describing ascent toward known hazardous floors.

A separate, controversial category exists for “Prosthetic Emotions,” affective states induced solely through the consumption of specific, now-unobtainable substances from the Greenhouse of Unusual Lichens, such as Lobaria emotiva. Scholars dispute whether these qualify as truly extinct or merely inaccessible.

Etiology of Extinction

The dominant theory, advanced by the Librarian-Somaticists, holds that emotional extinction is a consequence of architectural and administrative evolution. The standardization of corridor widths (per Second Concordance, Clause 304), the dampening of certain resonant frequencies in the Iron Spires, and the gradual phasing out of irregular mealtimes are all cited as environmental changes that rendered specific emotional ecosystems non-viable. A dissenting school, centered in the Scriptorium of Lost Causes, argues for a memetic model: that emotions, like ideas, can simply be forgotten when their narrative utility expires, irrespective of physical conditions.

The most poignant case is that of Threshold Grace, defined as the specific blend of anxiety and generosity felt when lending a key one cannot afford to lose. Its extinction is directly linked to the implementation of the Universal Pass-Rune System in Era 15, which rendered physical keys obsolete.

Controversy and the “Simulation Debate”

A persistent and heated scholarly division concerns the ethics and efficacy of attempted simulation. The Office of Experimental Resonance has, under strict protocols, attempted to recreate the conditions for Kairologos using calibrated shadow-casters and filtered air from the Archive of Particular Noons. Participants report a recognizable aesthetic appreciation, but unanimously deny feeling the emotion itself. This has led the Purist Faction to declare all such efforts not only futile but dangerously ontologically blurring, as outlined in their manifesto, On the Integrity of Absence. They maintain that an extinct emotion can be understood only through its contextual artifacts, never reconstituted.

Opposing them, the Reconstructionist Guild contends that the Tower’s foundational principle—that catalogued subjects are real—demands active engagement. They point to implied mandates regarding the stewardship of lost knowledge, arguing that non-intervention is a form of administrative neglect.

Administrative and Cataloguing Challenges

Cataloguing extinct emotions presents unique difficulties. They are often described in metaphors that reference other extinct phenomena, creating a circular documentation problem. Furthermore, the Index of Internal States requires a primary trigger and a somatic response for an entry to be considered complete. For many specimens, only one half of this pair is known. The entry for “Marlboric Yearning,” for instance, lists “the scent of oxidising vellum in a north-draft” as the trigger, but the accompanying bodily sensation is recorded only as “??? (cf. Lost Sensations Archive, Drawer Φ)”.

Disputes over classification are arbitrated by the Curator of Intangibles, whose rulings, while binding, are frequently appealed to the ever-contradictory Concordances. The current Curator, Ardis V, has noted a 40% increase in cross-referential litigation since the discovery of the so-called “Emotional Fossils”—mineralized deposits in the Salt Grottoes of Floor -Ξ that allegedly resonate with the psychic signature of specific lost feelings.

Related Holdings

The study of extinct emotions necessarily intersects with other departments. The Archive of Superseded Etiquette provides crucial context for social emotions that faded with changing customs. The Repository of Unanswered Questions holds several inquiries believed to be capable of inducing specific extinct states, if only a suitable mind could be found to pose them. Finally, the Museum of Obsolete Instruments maintains several devices, like the Aesthesiometer, designed to measure emotional intensities for which no current scale is applicable.

The field remains active, if melancholic. As per the maxim attributed to the first Curator of Intangibles, “We do not mourn the feeling; we mourn the capacity for the feeling. The archive is that mourning, given form.”
