"Formal equivalence" does not have any causal significance. > They don't have the same macroscopic properties Exactly... see the above... Whenever you taalk about "formal" equivalece you mean: ignoring the causal semantics for the formula describing the system. "2 + 2 = 4" is eqv. to "2 + 2 = 4" even when talking about wars, people, cars, animals, ... sand, cells, brains, bodies... NO, obvious not. This isnt hard, this is obvious. It requires some extraordinary magical thinking to suppose that field configurations of sand are equivalent to arbitary systems... this is obvious nonesense |
