2. The computational theory of mind

The theory says that the basic processes that govern the mind work in a similar way to other systems: that is, information transfer, processing, storage and output.
It musn't be confused with they way computers work. Rather, computers do work according to the computational theory.
1. Boolean logic can make informational processing easier, faster and cheaper. It is interesting to quote that information processing in the brain seems to have a similar architecture, although far more complex, to that of Boolean logic.
The primary architecture of a Boolean system is made of decision gates (neurons?), and its language uses binary number combinations (0,1).
2. The mind software, given the amount of input received from the outside, could resemble a Turing machine. That is, logic circuits that follow the classic computational rules: "if-then". They are, of course, programmable.

What do neurons use as an information system? We don't know and for the sake of this discussion, we will keep it aside.
This discussion if about the systems and their origin:
What is it about gates and binary information that makes them so universal?
