You say
> mental processes are computational processes
as if this were obvious but... If you accept the possibility of random events (something deeply related to Quantum Mechanics)... There can be lots of non-computable things out there in our minds...
- LolWolf 7y agoSuch as? "Computational processes" ≈ "arbitrarily approximable by a classical computer," and QM absolutely fits in there: I just solve Schrodinger's equation for the Hamiltonian you care about to whatever precision you need. It will take exponential time, but that seems perfectly reasonable.
- lisper 7y agoExactly. Furthermore, there is no evidence that quantum processes are at all salient to what the brain does. There is nothing in the I/O behavior of a human brain that provides any evidence of quantum processes going on. There are also good theoretical reasons to believe that quantum mechanic is not salient to the operation of the human brain. The brain is thoroughly thermalized, so it decoheres in time scales that are vastly faster than any of its interesting behaviors.
