Abstract

Here is an apparently straightforward philosophical story about concepts. In the style of Jerry Fodor, a concept is a mental “word” ; it means what it does because of its causal dependencies, and it contributes this meaning to the meanings of the mental “sentences” it helps to form. The mental word OWL means owls because owls have a special causal relationship to OWLs, and when the mental word OWL is combined with other mental words, such as THERE, IS, AN and NEARBY, the meaning of the resulting mental sentence, THERE IS AN OWL NEARBY, is a function of the meaning of the component words, plus the formal structure of the sentence. A cognitive system with these concepts is thereby able to represent the fact that an owl is nearby.
