One who ascends to one toposophic, then transcends to the next. For example an intelligence may ascend to S1, retaining everything (or at least some of its nature) it had beneath S1, then transcend to SI:2, leaving behind everything of itself that was of S<2. Contrast transcend-ascend.
Often, however, the dividing lines are not this well defined: these terms are purely seen from the modosophont perspective, so that an entity that 'ascends' sometimes presents itself to modosophont observers as an expanded version of the original entity, whereas a 'transcended' entity rarely or never does so.
From a transapient point of view there may be no significant difference between the two terms, and the way a transapient presents itself to modosophonts is only a minor aspect of its existential reality.
Transcendent Being - Text by M. Alan Kazlev An entity that is distinct from physical existence, whether considered ontologically, as a supernatural or supraphysical being, or soteriologically, as a being that is no longer a part of embodied existence or samsara. The existence of a transcendent being or beings (e.g. God, Buddhas, etc.) is central to many religious memeticities, but denied by physicalist memeticities.
Transcension Prediction - Text by Anders Sandberg and M. Alan Kazlev Given the huge population of the civilized galaxy, and the fact that ascensions and transcensions are moderately common and have been going on for thousands of years, many polities and civilizations have developed some fairly reliable methods for predicting the onset of one of these events. Often this is comparable to pre- and post-singularity efforts at predicting the weather (and a large transcendence event does indeed share some conceptual characteristics with a force of nature to those watching from outside at a lower S level).
