The five domains of toposophy in the Forad Classification scale; Non-sapients, Sapients, Transapients, Godlings and Archailects
Early in the second millenium AT, superbrighttoposophologist Anedra Forad created a scale of intelligence loosely based on the ancient biological taxonomy chart. There was "life", then "domains," "kingdoms," and "phylums." In subsequent revisions, the labels of kingdom and phylum were eventually changed to "tier" and "sub-tier" respectively, because they were seen as too specific to biology. On this intelligence scale, domains signify the boundary which separates beings of different toposophic levels. Tiers represent differentials an order of magnitude smaller, while sub-tiers represent those an order of magnitude smaller yet. If the scale was analogous to a ruler, then domains would involve metric sizes, tiers would involve decimeter sizes, and sub-tiers would involve centimeter sizes.
Although e would come to move well beyond it, Forad based eir initial work on one of the oldest principles of toposophy: That sapients display fundamentally different types of thought from non-sapients. Self-awareness and language are defining features for them which non-sapients lack. Beginning from this foundation, it logically follows that transapients can have modes of thoughts that are completely alien to modosophonts. Forad's great work was to organize and categorize transapient abilities (i.e., domain features) such as foresight and ideogenesis into a consistent and readily accessible taxonomy. Prior to Forad, transapient modes of thought had been seen as largely undifferentiated either within or across Singularity levels, and no formal classification system existed.
Transapient mental abilities were widely seen either as 'mere' incremental differences in cognition or else so alien as to be un-quantifiable. In reality, they are very broad ranging modes of thought that are homologous to all beings of that domain and above. For example, while non-sapients posses the capacity to feel emotion, sapients demonstrate a wider range of more complex emotions. And while sapients posses self-awareness, transapients enjoy an awareness of self that is far beyond sapient capacities. Conversely, non-sapients do not possess language and sapients do not possess foresight. Overall, the mental abilities that are unique to transapients have little or no overlap with modosophont minds, which is what made them so difficult to perceptualise. Forad and eir team would spend many years reviewing thousands of hours of video, text, records and other studies in order to sift out the question "what makes this entity different from the others?" The result would come to be known as the Forad scale, and is used to this day
Initially, the scale would include only three domains, all described in detail. These were non-sapients, sapients, and transapients. An incomplete list of the features of each domain would include the following: -Non-sapient: Cognition, sensation, emotion. -Sapient: Self awareness, language, rationality, abstractness, numeracy. -Transapient: Foresight, oversight, ideogenesis, translogic, autoscience.
Due to the far greater number of subjects (and their willingness to co-operate), it was unsurprising that the sapient domain was better described than the other two. The team concluded that sapients were best divided into three tiers each of three sub-tiers, for a total of nine. Somewhat chauvinistically, the three tiers were defined as subhuman, human, and superhuman. Forad and eir followers felt that this was a marked improvement over other intelligence scales in use at the time. It categorised entities based on the modes of thought inherent to each domain, rather than on other more arbitrary features. More importantly, it gave a proper name and description of those intelligence differentials that were smaller in scope than toposophic levels. This capability gap had been keenly felt in past generations, because notable differences in smartness had been observed in beings who were ostensibly at the same S-level. The Forad scale enabled the accurate measurement of a huge variety of intelligent beings, across domains, tiers, and sub-tiers. During the first century AT, for example, humans were only able to measure the smartness of beings in their own tier. Although the IQ test was eventually superceded by other scales, they often suffered from the same limited scope.
While this taxonomical classification was well received by the toposophy community, its overall philosophy was subject to criticism by some toposophologists. The scale seemingly ignored the importance of mind architecture. The most obvious example was how it was unable to quantify the intelligence of dedicated hyperturings, those strange artifices who drove much of Terragen civilisation. In addition, the emergence of S3 transapients indicated that the toposophic landscape was even larger than expected and extended beyond the bounds of the Forad scale as it existed up to that point. It was soon confirmed that these entities had domain features unknown to the S1s and S2s, modes of thoughts which could not even be vaguely summarized. Hence, the fourth domain of godling was added to the scale. The last canonical and accepted update was in the sixth millenium AT, resulting in a grand total of five domains.
AI God - Text by M. Alan Kazlev Popular term for the most sublime category of sentient being in the known galaxy: an Archailect or archailect cluster grown to godlike status. Something of a misnomer since in fact that not all archailects are primarily ascended ais; most are complex multibeings and incorporate postbiont or postvec elements.
Sophont - Text by Stephen Inniss A person. A being that has the quality of sophonce. Such beings are sometimes called 'sapients'. For historical reasons, sophont-grade ais, may be called 'turingrade ais', even though because of philosophical and practical difficulties with the Turing Test the term 'sophont ai' would be clearer.
