Computation and cognition: Toward a foundation for cognitive science. An extension of the productivity argument to deal with this sort of problem has recently been proposed by Fodorand Fodor and Pylyshyn Clark, Andy.

I will frame the discussion in terms of functionalism, because functionalism is the metaphysical doctrine most closely associated and conflated with computationalism. These fine points, however, are not critical for the issues under consideration here. Zombies v. If Strong AI is true, then there is a program for Chinese such that if any computing system runs that program, that system thereby comes to understand Chinese. See Figure 1. Such tables are, in effect, very low level computer programs. Unfortunately, that is an ontic state of affairs that is forever epistemically inaccessible to us: We cannot be any the wiser. Nonhuman symbols only have meaning if they are so interpreted by people; otherwise they are just meaningless "squiggles. These gates work in very different ways, but they are nonetheless computationally equivalent.

After all, if words can ever be understood other than linguistically, then the dilemma might be resolved without resorting to such an innate stock of semantic primitives, which is so complete that it includes concepts sufficient to accommodate any development--no matter how surprising or unexpected it might be--in art, history, science, or technology, including impressionism, totalitarianism, electromagnetism, and color television.

All other relevant knowledge, however, is permissible, and must, in principle, be accessible.

Sterelny, Kim. The question of what a primitive processor does is part of cognitive science, but the question of how it does it is not. Functionalism One of the most prominent views of functional explanation for a general overview see Causal Theories of Functional Explanation was developed by Robert Cummins Cummins ; Cummins ; Cummins The latter conclusion was reached by Putnam some time after drawing his analogy, on independent grounds.

As many of Searle's critics e. Critics stress that the analogy is relatively weak, and neurally quite implausible. Because of this, computers can acquire any number of new capacities simply by acquiring and switching between programs. For instance, imagine that you are given the strings "clb" and "fjb". Fetzer dualism and behaviorism There are two great traditions in the philosophy of mind that continue to exercise their influence in the age of computing machines. However the Virtual Mind reply holds that what is important is whether understanding is created, not whether the Room operator is the agent that understands. These arguments are mainly negative arguments that aim to show that the alternatives to functionalism are unacceptable. The outcome is a completely causal theory of signs and minds. The answer to this question would involve its chemical constitution: H2O. The Turing Test is an informal and open-ended test of whether or not people can discriminate the performance of the implemented simulation from that of a real human being. There is no question that one can write programs that mimic rationality, at least in a limited domain. Fodor and Pylyshyn point out that it is fact about humans that if someone can think the thought that Mary loves John, then she can also think the thought that John loves Mary. It is the activies of the symbols that gives them their meanings, so it is no mystery that a syntax-based system should have rational relations among the meanings of the system's symbols. Given these differences, the manipulation of syntax should be viewed as direct evidence of mentality for the computational conception but only as indirect evidence of mentality for the Cartesian. Cognitive scientists, I think, often forget that, prima facie, there is no more reason for psychologists to be interested in computers per se than they are in, say, toasters.

For a review, see Connectionism and Bechtel and Abrahamsenchap. In this way, the functionalist can incorporate the insight of the view mentioned earlier that meaning has something to do with covariation between symbols and the world.

By parity of argument, there must be far fewer that will enable it to produce grammatical English sentences. The system in the Chinese Room uses the wrong computational strategies. Tim Maudlin disagrees. What counts as the "right kind" of computation, however, is never made very clear, or at least has not been fully worked out as yet though Pylyshyn's notion of "functional equivalence" seems to be generally accepted, if not entirely clear. Parallels with the Turing test. As we have seen, Searle holds that the Chinese Room scenario shows that one cannot get semantics from syntax alone. Presumably, there are few if any other systems whose behavior is explained in terms of this type of program execution.
