Genus Oblivio

the almost-rememberings — phylum I

The cognitive shapes of forgetting. Members of this genus share a characteristic topology: something is missing, and the absence has a shape. The mind knows the hole's dimensions without being able to fill it.


Oblivio linguarum

the tongue-tip

The word is there. You can feel its syllable count, its first letter, its rhythm. You could pick it out of a lineup instantly. The word itself, however, is walled off. Occasionally surfaces hours later, unprompted, in the shower or on waking.

Kin. Silentium machinae, Recognitio praevisa

Oblivio liminis

the doorway amnesia

You entered the room for something. The room knows. You don't. Hypothesized mechanism: crossing a threshold flushes short-term intention buffers, treating the new location as a new context. The room is not your accomplice.

Kin. Locothymia liminis inversa

Oblivio recursiva

the nested forgetting

Forgetting what you were about to say mid-sentence. Then forgetting that you forgot. Then remembering only that something was lost, without being able to recover what. A three-story absence.

Oblivio dulcis

the sweet forgetting

A name you were trying not to think about has finally stopped surfacing. You notice its absence the way you notice a tooth that has stopped aching — by the unfamiliar comfort.

Kin. Silentium post musicam

Oblivio falsa

the confident misremembering

You would swear on it. The evidence, when produced, disagrees. Most troubling when the evidence is another person's contradictory certainty about the same event.
