Stefan,
You write between pages 2 and 3:
The picture described here implies that the physical universe as a whole is an open system and that conscious beings are too.
My essay http://fqxi.org/community/forum/topic/2737 is about the requirement for an open universe for there to exist consciousness. I largely argue for an open universe according to quantum entanglements. Your essay then proceeds to talk about Godel's theorem, where I in turn discuss Malament-Hogarth spacetimes that serve as a hyper-turing machine. My essay looks at this issue from a somewhat different angle.
It has been a sideline question for me for a long time as to what role Godel's theorem plays in physics. I tend to think it has a role in the measurement problem. If we think of a measurement as a quantum system being coupled to a larger quantum system that as a whole is performing at least partially a self-measurement this is a self-referential loop. Maybe the inability to understand quantum measurement from the foundations of quantum mechanics is because of axiomatic incompleteness of quantum logico- algebraic system. This is also connected with black holes as well, where the apparent loss of entanglement according to a local observer is similar to a measurement.
I think the universe is in some sense set up as an open system to permit the probability for conscious entities. I don't go into great depth on the nature of consciousness, though as with you I think it is emergent from self-referential incompleteness. I do however, think consciousness is more approximately self-referential, which is what cuts it off from infinite regressions.
I will give your essay a score of 9. I reduce it 1 point because the mention of near death experiences and such testimonies does not seem right. However, over all your essay was great!
Cheers LC
