I agree. In a way, all there are, are first person views. It's amazing
anything is communicable at all.

It's not obvious to me that understanding requires more than simply
"analysis of patterns". Patterns are all our brains receive from the world

Sensory input from the outside world is just patterns. Why should patterns
of activation in cells of the retina allow for an understanding to develop,
but not patterns of symbols in a corpus of text? The best I've gotten from
you is that we don't know how the brain works, but this doesn't help
convince me your view. Regardless of how the brain does it, we agree it
does it. This indicates it is possible to develop understanding from an
analysis of patterns. Therefore there must be some error in your reasoning
or assumptions that lead you to conclude this is impossible.
Otherwise, with respect to mathematical symbols, we are merely carrying out

Why do we feel it important to ascribe conscious to other humans or to

Occam's razor is about minimizing assumptions and complexity of theories.
For example, compare these two theories:
1. consciousness supervenes on any information processing system.
2. consciousness supervenes on any information processing system that uses
living cells as it's computational substrate.
Regardless of whether either of these is true, one theory is simpler, as it
doesn't introduce exceptions or complications that aren't necessary to fit
the facts and observations.
