The de dicto/de re distinction has provoked a good deal of controversy in both  metaphysics and in logic.  In this talk, Mendelsohn presents some of the many examples of the distinction that have been put forward in the literature, canvasses  the ways in which the distinction has been characterized, and discusses the relation between de dicto and de re claims.  One interesting facet of the distinction that he will develop  is the connection between de re modality and singular propositions.
