Dust particles are not a billard ball computer a la Fredkin/Toffoli.

A billard ball computer can be entirely reversible. The entropy increase
is not a computation requirement, it's just a case of evolving away from a high order
state, which is an infinitesimal island in the set of all possible states.

Whoa, there. There's a giant gap in logic, and no sign of a bridge across it yet.

It seems Putnam and Searle don't know the difference between a computer
and a rock. Given that Searle thought the Chinese Room was an example of
something other than the depth of his own ignorance, that's not a name
with a lot of ring to it.
As to Putnam, http://en.wikipedia.org/wiki/Hilary_Putnam does not
strike me as an impressive accomplishment track.
So, how many angels can dance on the head of a pin? And did Adam
really have a navel? Can God really make a rock larger than she
And do we really care?
