The mind as a symbol-manipulating machine

Since Turing’s time, cognitive science has also assumed the mind to be a symbol-manipulating machine, an analogy to the abstract mathematical Turing machine. But as the example of computers that can play chess illustrates, how a computer does math and how a human does math may be two different things entirely.

The Turing machine as an abstract concept

A Turing machine is a device that carries out calculations using only two types of symbols. These are usually thought of as zeros and ones, but any symbols…

Breaking the circle of meaningless symbols

How can symbols ever be grounded by anything but other meaningless symbols? Part of the problem of ascribing meaning to a symbol requires that the circle of…
