Abstract

For Perry and many authors, de se thoughts are a species of de re thought ; for Lewis, it is the other way round. To a large extent, the conflict between the two positions is merely apparent: it is due to insufficient appreciation of the crucial distinction between two types of de se thought. In view of this distinction, we can maintain both that de se thought is a special case of de re thought, and that de re thought is a special case of de se thought. Still, I argue, Lewis's position can be criticized on the grounds that it internalizes acquaintance relations.
