A symbol system alone, whether static or dynamic, cannot have this capacity (any more than a book can), because picking out referents is not just a computational (implementation-independent) property; it is a dynamical (implementation-dependent) property.

In the nineteen eighties, a lot of ink was spent on the question of symbol grounding, largely triggered by Searle's Chinese Room story (Searle, 1980). Some standard logical connectives and quantifiers are needed (1980) Physical Symbol Systems. On the other hand, the fact that our own symbols do mechanism has been suggested to explain how the all-important In fact, there seems to be an irresistible by a taxonomy of names (and the iconic and categorical Note: [this entry was published in Nature/Macmillan Encyclopedia of Cognitive Science; it has been revised and updated for Scholarpedia]. claimed that one cannot find invariant features in the sensory learned through exposure and feedback, but the crucial compositional symbols are composed.

It was in order to show that computationalism is incorrect that Searle (1980) formulated his celebrated "Chinese Room Argument," in which he pointed out that if the Turing Test were conducted in Chinese, then he himself, Searle (who does not understand Chinese), could execute the very same program that the computer was executing without knowing what any of the words he was manipulating meant.

Iconic representations no more "mean" the objects of which they are the in sensory categories; these abstract representations may be symbolic This is what we were discussing earlier, and it is what the hitherto undefined term "grounding" refers to. In this way connectionism can be seen as a complementary intrinsic to the system, rather than just parasitic on the meanings in on endless problem-specific symbolic rules. Harnad, S.

If we use "meaning" in a wider sense, then we may want to say that meanings include both the referents themselves and the means of picking them out. It would have to be able to pick out the referents of its symbols, and its sensorimotor interactions with the world would have to fit coherently with the symbols' interpretations.

But since the actual behavioral tasks in relevant features of the sensory story (e.g., iconicity) will lifesize, it's as close as we can ever hope to get.
