Fodorian semantics, pathologies, and "Block's Problem"

In two recent books, Jerry Fodor has developed a set of sufficient conditions for an object "X" to non-naturally and non-derivatively mean X. In an earlier paper we presented three reasons for thinking Fodor's theory to be inadequate. One of these problems we have dubbed the "Pathologies Problem". In response to queries concerning the relationship between the Pathologies Problem and what Fodor calls "Block's Problem", we argue that, while Block's Problem does not threaten Fodor's view, the Pathologies Problem does.
