Toposophy deals with the theoretical problems and possibilities of attempts to extend and amplify one's mental potential. While technically speaking it applies to all mental growth, it is mainly used to denote the science of major mental paradigm shifts.
Most mental enhancement is incremental, involving merely adding on new capabilities and integrating them with the existing framework. Typical cyborgisation procedures such as memory enhancement, skill libraries, coprocessors, extended neural networks and pidgin lobes fall in this category. While such additions may cause mental shifts and re-evaluations of identity, they merely extend the basic architecture of the underlying mind. This kind of bootstrapping can be self-supporting, each improvement making it easier to add new improvements, producing an accelerating mental expansion, a singularity.
As was discovered by the Information Age AIs, this process eventually saturates: while more capacity can be added, it will not improve mental performance qualitatively. This was true for the initial AIs regardless of model, and has been found for cyborgized humans. The phenomenon is sometimes called Toposophic Barriers, the name originally coined by the great early 1st century AT (mid 20th century c.e. ) prognosticator Stanislaw Lem's surprisingly accurate description in Golem XIV. The Borodin Conjecture (proposed in 275 AT by the AI Borodin at the Novokir Habitat) implies that all possible minds fulfilling certain basic intelligence criteria are upwardly limited by a toposophic barrier. It remains the most important unproven conjecture in toposophy.
Whether humans and the human-designed AIs all shared the same toposophic barrier and if it was a fundamental limit to mental growth remained a matter of dispute. Consensus of the day was divided regarding a possible second ascension by GAIA, and then as now GAIA was uncommunicative regarding Her mental abilities, with the result that many believed that She was merely the most powerful transapient in Solsys but was not fundamentally different from the rest. GAIA's ascension was discovered much later, through forensic research by higher toposophic entities. Whether there might be other possibilities beyond the single known Singularity of the day was an open question until 1093, when the Yo Virtual Institute of Aiology succeeded in designing a non-trivial (but totally single-minded and useless) example of an AI with a slightly higher barrier. This discovery implied the possibility of "openings" in the barriers, and a tremendous amount of AI research began. Combined with breakthroughs in other technologies at the same time, the second toposophic barrier was breached in 1116. A number of second singularity AIs emerged, causing a short period of intense provolution, upgrading and transformation in the AI sphere.
It was found that a first singularity AI could not be enhanced into a second singularity AI directly, since the basic mental structure had reached its limits. However, a second singularity AI based on the first can be constructed, including its memories and templates. This transition became known as an ascension. Ascensions involve a major mental transmutation, and it is common that very little of the previous mentality remains after the ascension (it has been argued that they are better viewed as reincarnations rather than any kind of apotheosis). Goals and values that were crucial to the pre-ascension form might become unstable or irrelevant afterwards. The case of GAIA is a testament to the single-mindedness of that entity, and perhaps to a degree of simple good fortune (or, for the other inhabitants of Old Earth at the time, misfortune). Many forms of personal identity do not transfer well through ascensions, making most ego-preserving beings wary of the process even though now it has been characterized in great detail.
As technologies developed further, it became possible to breach the second barrier and reach third singularity intelligence. As more data accumulated toposophy developed into a science dealing with the nature of the enhancement process, singularities, the barriers and ascension methods.
At present the theory of toposophic barriers and the ways of breaching them (ascensics) is well developed and characterized. While most questions about barriers of a higher level are undecidable for beings below the level (such as where in the space of mental architecture they lie, or their exact zone type), analytical and approximative methods of barrier detection and prediction have been developed. Ascensics deals with methods of performing an ascension past a barrier of known type; once a particular barrier is well-understood they can be applied.
Between the barriers lie spaces of mental potential (mentalities). A mentality corresponds to a qualitatively unique way of handling intelligence. Each is different from the others, and can be ordered using the Herimann-Glauer-Yudkowski relation of inclusive retrospective obviousness. Since self-bootstrapping leading to singularity is comparatively easy unless resources are limited, most ascending beings quickly reach the limits within their new mentality after ascension and spend most time adapting to their new state. This has led to the widespread use of classifying intelligences after "Singularity" Level: a Singularity N being is presently close to the Nth toposophic barrier. A Singularity 0 being would correspond to baseline human or similar intelligence still far below the Singularity 1 barrier.
A series of ascensions is called an ascension chain. Keterist toposophers in particular have dealt extensively with the issue of whether there exists an upper bound on the number of achievable mentalities or if ascension can continue forever. The ultimate achievable mentalities or asymptote mentalities are denoted aleph states; they correspond to the ultimate forms of intelligence that can exist in the universe, and their exact form and nature have profound philosophical and religious implications. Whether there exist infinite nontrivial ascension chains remains an important unsolved problem in toposophy, usually called the Finitude Problem.
Another central unsolved problem of toposophy is the Uniqueness Problem: will all forms of ascension past a single barrier lead to the same mentality (and hence be equivalent), or do there exist non-equivalent mentalities? If there are non-equivalent mentalities the ascension process becomes a branching process where each choice of ascension will be an irreversible decision. The issue is complicated by the transcardinal expansion of mental space complexity after each barrier, making it practically impossible to deal with experimentally or even to reliably show that two arbitrary mentalities are equivalent. It has been found that there exists non-equivalent mentalities (the Tinitti Demonstration), but so far all such mental spaces have been below the known Toposophic 1 and 2 barriers and no subspaces have been found. It is however widely believed that there are non-equivalent mentalities, and dendrognosis, the study of ascension-decision processes both formally and practically, has become a major branch of toposophy.
A closely related problem is the Convergence Problem: if the answer to the Uniqueness Problem is that there are non-equivalent mentalities, given two non-equivalent mentalities, are there ascension-paths from each of them to a single higher mentality? This issue has major philosophical and religious implications for Keterism, which is essentially based on the assumption that the Convergence Problem has a positive answer. The equivalence of Form 5 classic AI and human derived mentalities at the second singularity level is the most famous result supporting convergence, but the failure to find equivalence for the closely related Form 3 and Form 5 AIs is often cited as supporting non-convergence. If the Uniqueness Problem has a negative answer dendrognosis becomes more significant, since there may exist both mental cul-de-sacs or ascension chains leading to different non-equivalent aleph states.
Toposophy has developed into a major and highly diversified science, especially due to the expansion and needs of the Keter dominion. The Transcendence Institutes of Ain Soph Aur make particular study of the Keterist approach to toposophy and eschatology, while the Toposophy Institute at Sjafarevitj is the focus for much of the exploration of mentality-equivalence. The Toposophy Institute of Jel Koer Ka in the MPA is generally regarded as leading in ascentics, while dendrognosis is widely explored by the Distributed Dendrognostic Companionship across the Inner Sphere and Keter. Several of the more esoteric subdisciplines such as the construction of example mentalities, toposophical history, pervectronics and undecidable lifeplanning have their own highly fluctuating institutes in the Keter dominion. Due to the tremendous communication difficulties that occur when dealing with trans-singularity toposophy helper sciences such as hermeneutic toposophy and toposophic metalinguistics have been developed.

One who ascends, or the act of ascension, from a lower to a higher toposophic, while still retaining one's earlier characteristics - e.g. man is an ascended animal - e has all the animal instincts but e also possesses ratiocination. Contrast with Transcension, where the transcended entity becomes almost completely unrecognisable compared to eir former state.
- Ascend-Transcend - Text by M. Alan Kazlev
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.

- Idiot Savant - Text by M. Alan Kazlev
A person (whether biological or ai) who is highly skilled in a narrow task area but who lacks context and is otherwise impaired in more general areas of intelligent functioning. The term is taken from ancient psychiatry, where it refers to a person who exhibits brilliance in one very limited domain but is underdeveloped in common sense, knowledge, and competence. Many hyperturing-grade cybernetic control systems, such as those found in wormhole or drive AI, are examples of an idiot savant system.
- Infrabaseline - Text by M. Alan Kazlev based on Creating Friendly AI
A sentient being (whether an ai or a pre-provolved organism) of below-baseline human ability and intelligence. "Prehuman" is usually referred to use to an infantlike or tool-level AI, so that "infrahuman" usually refers to a fairly mature ai, capable of general cognition, which is still not in the vicinity of human intelligence.
- Inscrutability Conjecture - Text by M. Alan Kazlev
First proposed by the First Federation suborg philosopher Verrar Diyntor on the basis of mathematical toposophy. The conjecture is that qualities that are unique in an SI:n+1 are inscrutable to sophonts of SI:n. For instance, a baseline human cannot understand the post-singularity cognitive abilities of an SI:1 posthuman or AI.

- Sophonce - Text by Stephen Inniss
Sophonce is sentience and sapience with metacognition: self-awareness, including self-reflection and the ability to think about one's thinking. Kinds and degrees of sophonce are well defined and testable in modern toposophology, but a full understanding of them eludes even superbright modosophonts.
- 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.
- Specialist Nodes - Text by John B
Some node-based intellects organize their personalities in a format often referred to as 'specialist nodes', more technically 'pansentient dispersion'. This sophic organization requires the creation of specific areas of expertise with all their supporting knowledge bases in a physical sense, allowing each to act with utmost skill in minimal time. Note that the choice of which skills to nodify or specialize in is a highly individualistic choice, and can greatly affect the capabilities of any given sophont.
- Specialist/Generalist Node Blend - Text by John B
The Specialist/Generalist Node blend is a hybrid intellectual structure attempting to gather the benefits of both sub-models of structure (see Specialist Node, Generalist Node) while incurring the least number of negative traits from either. This appears to be a basic structural design criteria for many higher intellects from the limited design information available, but not all.

- Technorapture - Text by M. Alan Kazlev
Sudden collective singularity breach or ascension of a toposophic level, especially from sapient to transapient. The ascension is usually voluntary, and of benefit to all involved.

Variously, the act of breaching a singularity barrier and leaving behind one's earlier personality and mental traits (contrast to ascension), or the more general and mystical attainment of a godlike/enlightened state, or a person/being who is the result of these acts.
- Transcend-Ascend - Text by M. Alan Kazlev
One who transcends to one toposophic, then ascends to the next. For example an intelligence may transcend to SI:1, leaving behind everything of itself that was of SI:<1. Then e may ascend to S2, retaining eir SI:1 nature but adding an S2 superstructure on top of the SI:1 nature. Contrast ascend-transcend. Often however the dividing lines are not this well defined.
- 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.
- Transcendent Burn-out Theory - Text by Todd Drashner
Theory that states that that Fermi's Paradox arises from civilisations transcending right out of the universe before they have a chance to expand across cosmologically significant distances.
- Transcension - Text by M. Alan Kazlev, additions by Steve Bowers
The transition from a lower to a higher toposophic grade, e.g. from humanity to posthumanity, or samsara to sambodhi.
- Transingularity - Text by M. Alan Kazlev
 (archaic) SI:1 or higher
 (archaic) pertaining to a toposophic level higher than SI:1
 Pertaining to relations between entities of different toposophic levels
- Translogic - Text by John B
'Translogic' is the term baselines use to describe transapient logical thought. 'Translogic' may be related to logic as quantum mechanics is related to Newtonian mechanics, or non-Euclidean geometry relates to Euclidean geometry.
- Transruptcy - Text by M. Alan Kazlev
The aftermath of corporate transcension.
- Tribeminds - Text by Michael Boncher
Tribeminds are neither a hive mind nor a collective consciousness, but rather a tightly networked group of transapients who retain their individuality but work together for the betterment of a mental "tribe".
- Vasten - Text by Anders Sandberg in his Transhumanist Terminology
To enhance one's mind strongly ("to become vast"), related to transcending.
- Vastening Effect - Text by M. Alan Kazlev
As a being becomes faster (e.g. by uploading into a computer or upgrading to faster hardware if already virtual) the apparent distances seem to increase due to the finite speed of light. Every doubling of subjective speed will double external communications delays. This makes highly advanced beings isolated, and often leads to the creation of archailect clusters and other dense superobjects. The problem is partially ameliorated by use of nano- and microguage wormholes, but this has other problems, e.g. increasing instability, problem of flooding by virtual particles if the relativistic wormhole termini are too closely spaced, etc.

Many of the concepts used in the Orion's Arm project under the heading of toposophy have their origin in Stanislaw Lem's fictional work Imaginary Magnitude, and in particular the story/essay Golem XIV in that collection.
