This paper presents a theory of control (predication), in terms of thematic relations, which makes no use of the element PRO in the syntax. Important consequences of the theory are that the θ-Criterion must be relativized to particular local domains, and the Projection Principle cannot be maintained. A number of syntactic arguments against PRO are summarized, and the arguments of Koster & May 1982 in favor of PRO are addressed. It is concluded that, given a thematic relation-based account of predication, the Projection Principle in its current form is not a useful postulate in the theory of grammar.
