The lines are too large for my screen to handle but I have fixed that by
setting my Netscape to wrap automatically (it does so at around 70
characters). The output is irregular but it's OK.

The limits may just be different orders of infinity.

Immortality does not have to be based on Quantum Theory. It can be
derived from basic philosophical considerations borrowed from the
Anthropic principle, Descartes and Leibniz (all possible worlds). What
Barbour calls Platonia some philosophers call the Plenitude.

The evidence for the Plenitude (Platonia) is the Principle of sufficient
reason or more simply, causality (or the lack of). In the absence of any
cause, for any given instance, all other possible instances must also
exist. For any instance of universe (ours), all other possible universes
must also exist. Hence, the Plenitude. Note, that by invoking the
"absence of any cause", this derivation specifically steers clear of the
"Creation by Design" argument.

In addition, this reliance on rationality, combined with the anthropic
principle, leads to a theory of consciousness: "I am rational because I
am conscious." Bruno may have found a way to express this using a modern
mathematical formulation.
