minor adaptations for a general reading audience, the eight chapters in

Abstract Performance Grammar. The book in your hands is an anticipation
of this work in at least three senses: for one thing, it doesn't pretend

philosophy and psychology (as well as in various applied fields like
second language learning and bilingualism); and for yet another thing,
many sections of the planned magnum opus are hardly even touched on
