Consciousness is the feeling information has when it is being processed; if
conscious is fundamental, that is to say it comes at the end of a long line
"what is that?" questions, then after saying that there is just nothing
can be said about it. And hey, it's just as good as a billion other
Ah yes, Max Tegmark's "theory".These aren't theories, is the problem. One needs a
rigorous definition of what consciousness is, to start with, and then a theory that
explains all its observed features, and makes testable predictions. Otherwise all one
has is a jumble of words.
To be precise, we don't need a definition of what consciousness is. WE need only to
agree on some assertion on consciousness. It is the same with line and points. The same
with natural numbers. We don't need to define them (in fact we can't). We need only to
agree on axioms about them, and methods or rules of logical inference/deduction.
And we learn what are natural numbers in the same way, ostensively by one's mother holding
up fingers and saying "one", "two",... And so we generalize and make a theory about
fingers and other countable things. And we know that in all cases we run into we can add
one more and so we casually assume an axiom of infinity because it is convenient and seems
to cause no problems. But if it leads to paradoxes and absurdities...
