If I understand you correctly, you're saying that, since brains are
built out of things that act probabilistically, there is some
inconsistency with their "running" of a logic that is not
probabilistic.  Why is this so?  One can implement an analog neural
network, with arbitrary accuracy, on a digital computer and can
implement a digital system with analong components.  In fact, the
logic gates in a computer, if I am not mistaken (I'm certainly not an
electrical engineer--this is a hardware problem), are devices that, by
switching very fast, simulate a two-state bit, which is a logical
entity.  There are times when the gate is between 0 and 1, but these
intervals don't impair the gates' ability to implement a digital
computer.
