Where now with Optimality Theory?

In this article I discuss the various parts of the OT architecture in phonology: its basic structure as an input-output system, Gen, Con and Eval. These aspects are considered in the light of the question what is innate in language (i.e., part of Universal Grammar) and what could be based on acquisition (i.e., experience with language). We will see that all parts of OT can be related to general cognitive learning strategies, obviating the need for any assumption of innateness. It is hoped that future research in this area will bring OT closer to the field of general cognitive science.
