Mysticism is folly. Existence, as perceived via the five senses, is permeated with unknowns, but none of them are supernatural.
Unexpected, bizarre new discoveries are just as natural as the most commonplace objects and circumstances. That which is highly unlikely or impossible according to current scientific understanding should be regarded with appropriate suspicion.
Mystery extends endlessly into the profound. Mystical faith cuts mystery off by asserting knowledge, however "transcendental", or by imposing necessarily arbitrary forms upon the incomprehensible.
Mystery and its infinite possibilities begin not with the unlikely, but with the very simple. Anything that is not known is, of course, unknown. This ranges from the minuscule to the massive — from the world beyond blinking eyelids, to the thoughts of minds beyond one's own, to that which outdistances our gaze into the cosmos.
Every unknown hosts infinite possibilities. Any single part of the universe has innumerable possible relationships to any and all other parts of the universe. Any potentiality is a potential possibility.
This is an essential point: It is not necessarily true that absolutely anything is possible. Rather there are infinite possibilities.
This is infinite mystery based within reality. Existence swallows new possibilities in seamless succession, in each of these infinitesimal moments neglecting innumerable alternatives.
What is of interest to me in the extreme depths of the unknown is not what might be, but in the sheer intellectual stimulation elicited through the contemplation of extant infinitudes.
There's too much to be said about this all at once; this will be a persistent topic in my writing, as it has been for over a decade.
