Safir's monograph develops a theory about the role of anaphora in the formulation of general syntax. He presents the following proposals: firstly, that the complementary distribution of forms that support anaphoric readings is not accidental; secondly, that dependent identity relations are always possible where they are not prohibited by a constraint; and lastly, that there are no parameters for anaphora - that all anaphora-specific principles are universal, and that the patterns of anaphora across languages arise entirely from lexical properties. The goal of this thoroughly comprehensive look at the phenomenon of anaphora is to fundamentally redirect current thinking on the subject.
