May I begin by reminding you that when we use the term know-nothing state, we are speaking without precision - what we actually are referring to is a set of know-nothing states. Let's suppose that all know-nothing states are characterized by the full suspension of f2 filters - all language and all other f2 impositions are set aside and we play at FA. If you acdept this characterization, then know-nothing states and what I take to be Casteneda's "stopping the world" are equivalent functionally - although the way you get there might be quite distinct. As to the sensing shifts - yes, these are all to be anticipated and embraced - one of the delights of living at FA is the richness of the sensory world - remember the price that language extracts is high - what you are recovering is that price. In particular, you ask about the perceptions of speed in the 180 degree sphere - it is interesting that you select the term "time distrortion" as my proposal would be the normal (with f2 filter operating) perception of variable speeds around you is the "distorted" one (additional f2 filters stabilizing it to create the illusion. You will note that the epistemology that Carmen and I present in Whispering argues that FA itself is an already transformed (or "distorted" if you prefer) representation of what's out there but less transformed as it has not been subjected to the f2 filter - an additinal layer of "distortion". You are correct that I use different members of this set of know-nothing states in modeling - specifically, phases 2 and 3 which include unconscious assimilation. Finally your point about know-nothing states being well-contextualized is well-made. Part of any useful taxomony refining the general set of know-nothing states will surely refer to such distinctions. John
