Fodor's denotational conception of the lexicon says that 'dog' means dog, and so on for the words in the lexicon. All of these meanings are atomistic, meaning that they have no internal structure and that they have no inferential relations to other words. I haven't read any of Fodor's main works explaining his theory, although I have read Concepts. A couple of questions just occurred to me. Am I correct in assuming that Fodor's lexicon has the following entries: 'I' means I; 'those' means those; 'yes' means yes; 'of' means of. These are pretty obviously wrong, so I'm curious what his theory actually says.
