Zero.
Does that allow us to argue:
1) A universe selected from an uncountably infinite number of
possibilities has measure
0
2) Our universe exists so it has measure>0
3) Our universe is not selected from uncountably infinite
possibilities
4) MUH indicates any universe must be selected from uncountable
infinite possibilities (since all
of maths includes the real line, etc)
5) MUH is false.
Hmmm. I think we argue that objects in Plato's heaven and Turing
machines are not the right kind of things to support life.
I am very puzzled by this statement. You could help me understand
by answering the following questions:
Why couldn't there be an accurate simulation of life on a Turing
machine?
How can entities within a universe that exists in Plato's heaven
distinguish it from a universe that does not?
That is a good argument which convinces many people, who actually ask
"what is the MGA for?"
Here I can imagine what 1Z could answer to "How can entities within a
universe that exists in Plato's heaven distinguish it from a universe
that does not?".
He assumes the existence of primary matter or of a primitively real
physical universe, and will, by decision, attribute consciousness,
only to the creature made off that primary matter, even if the
consciousness relies in the computation implemented in that matter. So
1Z accepts the idea that arithmetical truth is full of zombies, like
the "1Z" described in arithmetic through the arithmetical emulation of
our galaxy (say).
But that moves is made impossible by the MGA. To attach consciousness
to matter, you have to introduce something non Turing emulable in that
consciousness, or, like Jack Mallah did, attribute a physical activity
to a piece of matter having no physical activity at all relevant with
the computation. But this prevent to say "yes" to the doctor *qua
computatio*.
Do you (the reader of the list, not Jason) agree with the 323
principle? If the physical running of a computer entails some
consciousness, and if that running does not use the register 323, does
the same running of that computer with the "323 register" deleted, run
the same consciousness, or not?
