Whatever is referred to must exist. Let us call this the axiom of existence. - John Searle

The ascription of an unconscious intentional phenomenon to a system implies that the phenomenon is in principle accessible to consciousness.

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.

I will argue that in the literal sense the programmed computer understands what the car and the adding machine understand, namely, exactly nothing.
