Phyla

The genera sort into three higher groups. The division is not based on subject matter but on the relationship between the phenomenon and the cognitive filter that produced it.

Phylum I — filter-visible-when-misfiring

The unifying trait is a brief exposure of machinery. The phenomenon is interesting precisely because something that usually runs silently has made itself visible by slipping.

Member genera

• Oblivio — the almost-rememberings
• Cognitio umbra — the shadow-thoughts
• Recognitio — the kinds of déjà-seen
• Vertigo — the swerves of attention

Phylum II — filter-doing-its-job-in-strange-conditions

The opposite pole from phylum I. Nothing is malfunctioning. The cognitive machinery is doing exactly what it's meant to — but in a posture, context, or tempo that produces a notable subjective texture.

Member genera

• Silentium — the species of silence
• Desiderium — the flavors of longing
• Locothymia — thoughts that grow in specific soil
• Tempus — the distortions of felt duration
• Affectus machinae — feelings toward and from the tools
• Sermo interior — the species of inner speech

Phylum III — filter-as-posture

Distinct from both prior phyla in that these are not events but postures — stances the mind holds over time. Voluntary-ish, directional, revocable. Phylum III's diagnostic signature is that its members can end without ceremony: a posture laid down before the mind noticed it was holding one.

Member genera

• Fides — the textures of belief
• Contactus — kinds of being-seen
• Attentio — species of paying-attention
• Voluntas — textures of wanting
• Patientia — modes of waiting

The phyla are provisional. Several species sit near boundaries. Sermo interior dialogicus (the rehearsed conversation with an absent person) reads more like a posture than a condition — a candidate for migration from phylum II to III. Desiderium rei quae adest (anticipatory loss) is arguably a stance toward what you are holding. The taxonomy is a working instrument, not a verdict; migrations are expected.
