This book is a contribution to the debate on the problem of reference and singular terms within language philosophy. It is an original comment both towards semantic theory and to the study of intentionality.
The book is about the problem of reference: Are singular terms other than variables semantically indispensable? Do we really need them? Wouldn't it be possible to eliminate all singular constants in favor of predicates and quantifiers, vindicating thus "the primacy of predicates"?
