talisqor: (from talis “truth” + qori case tag: standard): the perspective of truth; objectivity, science, and mathematics; reality-as-it-is; existence; history; positive claims.
aelvaqor: (from aelva “beauty” + qori case tag: standard): the perspective of beauty; ambijectivity, art, and the numinous; reality-as-it-ought-be; creation; mythology; normative claims.
alathqor: (from alath “wisdom” + qori case tag: standard): the perspective of wisdom, that attained by the simultaneous affirmation of both talisqor and aelvaqor in fullness, dwelling in the eye of the paradox; see also tarev i-alathqor, “the task of wisdom’s perspective”, the Flamic challenge to bring about the perfect marriage of the two in an unflawed universe, the March of the Flame Against the Fall of Night.
(I must at this point acknowledge a great debt to Scott Alexander and his own worldbuilding project, Raikoth; those familiar with it or his blog posts about it on Slate Star Codex will no doubt have felt a sense of familiarity on reading the words above. The ideas expressed in that particular link helped greatly to clarify some ideas on the shape of the Imperial noösphere I’d been kicking around for a long time without fully congealing, arising from my own ruminations and various inspirations – notably, for one, Pratchett’s Hogfather – so all credit where it is due.)
