BIALITY: (1) This is the functional range of ordinary consciousness: it defines and confines normal men's perception of how things are; it allows at best, thought to see only two sides to any issue, two aspects in fact, of Life itself. This limited condition does not spell failure in man, but in his mental view of things, provides a balance which makes possible his practical actions in an otherwise confusing and often out-of-kilter, contradictory world.
(2) Because men conceive of only two (instead of the ever present three, and ultimately the undifferentiated whole) each person's vision of things (particularly in man's spiritual, cultural, "un-touchable" realm) is always incomplete: every man's conception of what is real is but partial -- and thus always in partial conflict with other men's; this friction supplies needed fuel to the engine driving man's incorporeal world but furnishes nothing useful to the consciousness of the man out to solve The Puzzle.
(3) The special investigator is helped to keep alert by his resistance to the continual appearance in his own thinking of the Biality; his jarring reaction to his mundane mind's incessant presenting of two doors, one of which it assures leads toward the solution; this serves to remind the secret Sherlock of what a dunce man's natural thinking can be. He shoves his thoughts first into Triality (to instigate the process of original thinking) and once underway, storms his way into the heretofore alien land of: Ideas-never-thought-before (which blow all other ideas out of the universe). --
