Overlord, I am certainly open to the possibility of SRD making mistakes. I've pointed out several of them myself. Whenever his work seems to contradict my own personal interpretations, that's usually the first thing I suspect! (It couldn't be that
I made a mistake.

The bonefire "appearance" might have been a combination of: aggressive use of metaphor, character hallucination, careless writing, or simply a consistency error. I don't know. What I do know is that anything we observe
in this world cannot possibly prove the existence of an entirely separate world. I don't care how bizarre it is, it's still a phenomenon of this reality--if we're experiencing it
here. Whether or not it comes from beyond this reality is pure speculation, never arising to proof.
At the most, Foul's "appearance" either says something transcendental about the characters, or something transcendental about the "real" world. And, I believe, the same could be said about the Land in general.
Nerdanel, the computer analogy to consciousness can be misleading. Computers are not self-conscious, nor do I believe they can be, not without a radical departure from what we currently think of as computers. I don't care how many parellel processors you put on your mother board, they will never achieve self-consciousness. Self-consciousness is NOT an algorithm. No amount of complexity turns an algorithm into a conscious being. Simulations of consciousness might be possible; in other words, it might be possible to create the appearance of consciousness
from the outside. But subjectivity--the
appearing to oneself--is something we have no idea how to create. We don't even understand it within ourselves.
Forget self-consciousness. ANY kind of consciousness has two parts: subjective part, and an objective part. My consciousness of an apple includes both the appearance
of the apple (the objective part) and the appearing-
to-me (the subjective part). Consciousness has this dual-directional aspect. Now you can have computers relate to objects or manipulate objects, but there is nothing in their algorithms that creates this "appearing-
to-me" quality.
And it is precisely this part of self-consciousness which produces the paradox. We can think about the subjective part, make it an object of our consideration (like we're doing right now in talking about it), and in this sense we objectify it. But we don't reduce subjectivity into objectivity. We don't eliminate it. A subjective aspect always remains. And this is that part that "retreats" as we try to turn our attention to it. The
tail of the dog trying to catch its own tail. The "forkbomb" isn't like this. An endless process on a computer is an endless series of objects, not subjective states. In addition, an endless, nonterminating calculation can still be represented by one algorithm. So its endless nature isn't the result of a paradox like the endless retreat of subjectivity away from its own subjectivity.
The particle "model" of matter isn't a merely simplistic picture to help students. Matter does actually behave like particles in certain situations--usually measurement events. The electron probability cloud can be "collapsed" into discrete particles by measuring them. We can calculate the exact mass or position of an electron or proton--something we cannot do for waves. Waves don't have particular masses or positions. Even light is emitted in discrete photons. The particle nature is REAL. It is precisely because this particle nature is real that its wave behavior is paradoxical!
The wavelike nature of particles is in their probability. They have a probability of being in a certain spot before measuring them. But once we measure them, they never look like waves. They look like particles. The wave phenomenon makes itself known in the group behavior of individual particles; it is a wave of probability that is exhibited once you have enough instances to trace out the wave.
As for Heisenburg's Uncertainty Principle, it has nothing to do with our measuring technique disturbing the picture, because we can measure as precisely as we wish any one single property. Our interference can be accounted for. The energy of a photon, for example, is known, so we can subtract its disturbance from our measurement. The uncertainty I'm talking about goes well beyond practical limitations; it's a fundamental property of nature. It's not an issue of "cheap, fast, reliable--pick two" at all. You're talking about practical issues. I'm talking about a principle of nature, dictated by properties of matter, not measuring limitations.
Here's what Wikipedia has to say about it:
Mathematics provides a positive lower bound for the product of the uncertainties of measurements of the conjugate quantities. The uncertainty principle is one of the cornerstones of quantum mechanics and was discovered by Werner Heisenberg in 1927. The Uncertainty principle follows from the mathematical definition of operators in quantum mechanics; it is represented by a set of theorems of functional analysis. It is often confused with the observer effect.
However, Heisenberg showed that, even in theory with a hypothetical infinitely precise instrument, no measurement could be made to arbitrary accuracy of both the position and the momentum of a physical object.
The uncertainty principle in quantum mechanics is sometimes erroneously explained by claiming that the measurement of position necessarily disturbs a particle's momentum . . . . Such explanations, which are still encountered in popular expositions of quantum mechanics, are debunked by the EPR paradox, which shows that a "measurement" can be performed on a particle without disturbing it directly, by performing a measurement on a distant entangled particle.
And completely unrelated, but cool nonetheless, is this:
* In Stephen Donaldson's Gap Cycle science fiction book series, one of the characters postulates a socio-political version of the uncertainty principle: namely, that by determining his precise "location" in the current political landscape, he is prevented from simultaneously calculating the likely direction of political events in the near future.
