“Why, sometimes I've believed as many as six impossible things before breakfast.” --Alice in Wonderland

There is a whole move that remains to be named, its source, its purpose not clear from the use: to proceed as if some impossibility were fact. This is separate from the "what-ifs" of conjecture or the "they say" of received stories. It’s not only dream logic, which would be true if dream-things were real, or wishful thinking. It points towards transcendence, towards the unsayable, towards the absolute. Mystery & the most vital parts of all art unite in an asymptote that is at once a horizon & a release from ego.
The category of the impossible includes things which violate known physical limits (Element 139, Pleiadeans, the Wow! Signal, unpronounceable words, stars that are green), things which have now been falsified (ghost planets, apocryphal books, magic, debunked ideas, perhaps time travel), things that seem self-contradictory (the Esperanto Koran, unreadable books, the "living dead", conlang archaicism, alternative histories), & finally, the realm of paradox itself (i include here infrared photography, animal painting, & computer poetry--arts which are highly problematical in conception--as well as various koans & Sufi tales). --Except for the fact that most paradoxes are merely verbal, "paradox" would be a better name for it than “the impossible."
If we consider that the ego is both true & false (metaphorical) but invariably taken for true, it becomes significant that catharsis catalyzed by art-in-experience might be a change in truth-states; also, in more contemporary relevance, it might become clearer just what the threat consists of, when a depiction of the Prophet is offered.

In a field of non-duality, the impossible exists in its obvious form without complications. In a field of forced duality, however, many things of other truth-value become either forbidden or fascinating (i. e. unresolvable). The acme of these is the impossible, & it stands for all the rest.
Fascination with the impossible can end with the relinquishment, not of the object of fascination, but of the dualistic field in which it is embedded. This is a recognition—"dementation"—that creates the possibility for change. This is what koans do. Anything that means deeply enough can be a koan. But every koan has a simple, false name that must first be destroyed. "Nothing must come/ Between you and the shapes you take/ When the crust of shape has been destroyed." --Wallace Stevens. Meister Eckhart: "I pray to God to free me of God."

Every misprision has its corresponding recognition. One could make an analogy with chemical reactions: to make or unmake a misprision requires or releases (psychic) energy. The conversion-experience. The frisson of insight. Intellectual beauty. Are these truly misprisions, or simply react as if they were? "...human kind/ Cannot bear much reality." --When there is only: Love as Love, Death as Death...

"Many the thyrsus-bearers; few the initiates."
The history of philosophy is not a history of continual progress, like the history of science, but a history of intellectual fashions, like the history of art. There has nearly always been a fruitful tension between the sayable & the unsayable, never quite reducing one to the other completely, never quite resting in a final balance. Meanwhile the spontaneous generation of mythemes continues apace, more or less unhindered by the tamper-fingers of philosophy. Looking at it from a standpoint of multivalent logic, one can see that this division of labor has been justified, to the extent that it allows free reign to those who want dogma as well as those who resist it, at least as long as neither party obtains political power. One can imagine representatives of these estates sitting down to some kind of peace talks, but not that they might walk away content with their concluded negotiations. I can only offer on my part the observation that those philosophers who are still read either bring an engaging personal accent to their reflections, or express to the illumination of later celebrants a sense of "the one perfect [mystery] which filleth, foldeth all" (Clark Ashton Smith).
