Binding Conditions A and B are quite useful generalizations, but they raise many fundamental questions such as 'why must an anaphor be bound within a local domain, but not outside of it?', and 'why does a pronominal obey an almost opposite constraint?' and 'how is the local domain defined?'. This article explores the possibility of providing answers to those fundamental questions by assuming that binding conditions have both lexical and syntactic aspects. I claim that self is a reflexive predicate that requires its two arguments to be co-indexed, whereas a non-reflexive predicate like like requires its two arguments not to be co-indexed.
