The Minimalist Program consists of four recent essays that attempt to situatelinguistic theory in the broader cognitive sciences. In these essays the minimalist approach tolinguistic theory is formulated and progressively developed. Building on the theory of principlesand parameters and, in particular, on principles of economy of derivation and representation, theminimalist framework takes Universal Grammar as providing a unique computational system, withderivations driven by morphological properties, to which the syntactic variation of languages isalso restricted. Within this theoretical framework, linguistic expressions are generated byoptimally efficient derivations that must satisfy the conditions that hold on interface levels, theonly levels of linguistic representation. The interface levels provide instructions to two types ofperformance systems, articulatory-perceptual and conceptual-intentional. All syntactic conditions,then, express properties of these interface levels, reflecting the interpretive requirements oflanguage and keeping to very restricted conceptual resources.The EssaysPrinciples and ParametersTheory.Some Notes on Economy of Derivation and Representation.A Minimalist Program for LinguisticTheory.Categories and Transformations in a Minimalist Framework.
