Just listened to a talk Robert Anton Wilson gave about general semantics. He's a good speaker, humorous. He mentioned reality tunnels a few times, talked about confusing the map with the territory, which I guess comes from Korzybski.
Didn't really get into the topics at hand, here, though. Just mentioned it cause it was the first time I've heard/read "reality tunnel" coming from him.
A reality tunnel seems to describe a particular view of shared reality, a view that imparts a particular perspective, a perspective against which values are formed.
Something about values/positions are necessarily limited in scope - positions can only be taken from perspectives that only get part of the picture. Seemingly, the kind of all-knowing perspective described indirectly by certain enlightenment discourse is a perspective that does not take positions, does not even speak, or if it does it does with marvelous discretion.
But perhaps there are still positions available to such a perspective. Such positions would be the sort of higher order net-schizo-meta-position I was describing in some other thread, maybe this one.
But the thing with reality tunnels, if we do consider them perspectives with different value frameworks, is that a shift in such a perspective does not merely provide a different angle on the same system. It does, but it is not felt that way, at least not always. Rather it may be felt as a restructuring of the system itself, a restructuring of reality, which impresses upon you in a phenomenally despotic manner, no?
Perhaps it is worth remembering that the particular nature of this despotic ambiance is, itself, contingent upon your situation. That is, your reality is contingent upon the forces of influence you are subject to.
