Misplaced Modification and the Illusion of Opacity

In a number of groundbreaking publications, John Perry has stressed the importance of avoiding a class of fallacies that he and Barwise (1983) formerly called Fallacies of Misplaced Information and that Perry (2001) now prefers to call subject matter fallacies. One commits a subject matter fallacy when one supposes that: …the content of a statement or belief is wholly constituted by the conditions its truth puts on the subject matter of the statement or belief; that is, the conditions it puts on the objects the words designate or the ideas are of. (Perry 2001) Avoiding the bewitching influence of subject matter fallacies, Perry has argued, is one key to seeing that two alleged failures of referentialism-viz., its apparent inability to solve both what Perry calls the co-reference problem and what he calls the no-reference problem-are really only apparent.

The no reference problem is the problem of explaining how possibly, consistent with referentialism, names entirely lacking a referent may be cognitively significant at all. Naïve forms of referentialism maintain that all there is to the meaning, semantic content, or cognitive significance of a name is its property of standing for a certain
