Dear Russel, Could we associate this "psychological time" with the orderings that obtain when considering successive measurements of various measurements of non-commutative canonically conjugate (QM) states? Also, re your Occam's razor paper, have you considered the necessity of a principle that applies between observers, more than that involved with the Anthropic principle? Something along the lines of: the allowable communications between observers is restrained to only those that are mutually consistent. We see hints of this in EPR situations. ;-)

The observer needs a a temporal dimension in which to appreciate differences between states. "Physical time" presupposes a physics, which I haven't done in "Occam". It is obviously a little more structured than an ordering. A space dimension is insufficient for an observer to appreciate differences, isn't it? Cheers snip
