The assertion fallacy is the fallacy of confusing the conditions for the performance of the speech act of assertion with the analysis of the meaning of particular words occurring in certain assertions.

Well, what does "good" mean anyway? As Wittgenstein suggested, "good," like "game," has a family of meanings. Prominent among them is this one: "meets the criteria or standards of assessment or evaluation."

There are clear cases in which "understanding" literally applies and clear cases in which it does not apply; and these two sorts of cases are all I need for this argument.

It seemed to a number of philosophers of language, myself included, that we should attempt to achieve a unification of Chomsky's syntax, with the results of the researches that were going on in semantics and pragmatics. I believe that this effort has proven to be a failure. Though Chomsky did indeed revolutionize the subject of linguistics, it is not at all clear, at the end the century, what the solid results of this revolution are. As far as I can tell there is not a single rule of syntax that all, or even most, competent linguists are prepared to agree is a rule.

In the performance of an illocutionary act in the literal utterance of a sentence, the speaker intends to produce a certain effect by means of getting the hearer to recognize his intention to produce that effect; and furthermore, if he is using the words literally, he intends this recognition to be achieved in virtue of the fact that the rules for using the expressions he utters associate the expression with the production of that effect.

The reason that no computer program can ever be a mind is simply that a computer program is only syntactical, and minds are more than syntactical. Minds are semantical, in the sense that they have more than a formal structure, they have a content.
