Right! Nothing "has to obey" the Uncertainty Principle. Remember that the outcome of any experiment can only be predicted with a probability. So it's "possible" that we could make consecutive alternate measurements of an electron's position and momentum, and find that they seem to be well defined. But that's not usually what is seen. The odds of that are very small. I think (if I may be so bold) that James was trying to point out that we are in a universe that has a lot of non-sensical things going on - just very rarely. If we assume that this idea of a measure over universes is possible to define, then there *will* be some mathematically derivable laws of physics (read, "laws of probability") based on the relative SSA - that is, what the next conscious observer moment will be, given the current conscious observer moment. We'd like to show that these laws are the ones we observe. Regardless, it seems plausible to assume that the laws connecting observer moments when the observer is, say, 10 years old, are qualitatively the same as those when she's, say, 30 years old. Hence consistency. Hence, no flying rabbits. -- Chris Maloney http://www.chrismaloney.com "Knowledge is good" -- Emil Faber
