This book provides a fascinating and highly individual perspective on language. It deals with a wide range of topics including the philosophy of language, its biological basis and evolution, as well as language acquisition, language disorders, language processing and language universals. Andrew Radford, Emeritus Professor of Linguistics, University of Essex, United Kingdom Joseph Galasso builds a beautiful explanatory edifice that, engagingly, weaves together empirical evidence and current abstract theory of grammar in the best tradition of science: it combines a passion for abstraction with a devotion to detail. Implications for language acquisition, philosophy and every dimension of biolinguistics are skillfully incorporated with a core representation of the concept of recursion. It should be very useful for scholars and students alike. Tom Roeper, Professor of Linguistics, UMass, South College
