"David Lightfoot is addressing the core questions of the study of language: what it is, how it comes to be that way, how the child acquires it. His account is richly textured, integrating many different approaches with lucidity and insight. His analyses and conclusions are challenging and provocative, both for specialists in the particular areas he brings together, and for those seeking a clear picture of current understanding and open problems." Noam Chomsky
'There can be little question that it will represent a major work, required reading for anyone with interests in this area.' Mark Hale, Concordia University
"This book challenges conventional understanding of language learning by showing that language change is essentially contingent-unpredictable but explainable. The role of natural selection in facilitating the understanding of the evolution of the language faculty in the human species is contested." Psycholinguistics
To answer these questions, David Lightfoot looks closely at young children. A child develops a grammar on exposure to some triggering experience. A small perturbation in the trigger may entail a different grammar in the next population of speakers, with dramatic effects. This "sensitive dependence on initial conditions" is the key to explaining how languages change, and why they change in fits and starts.
The "cue-based" approach to language acquisition presented here is a radical departure from formal models of language learning. Lightfoot challenges conventional understanding by showing that language change is essentially contingent - unpredictable but explainable; and he contests how far natural selection enables us to understand the evolution of the language faculty in the species.

2.0 out of 5 stars
A decent introduction to Historical Linguistics,
By A Customer
This review is from: Development of Language (Blackwell/Maryland Lectures in Language and Cognition) (Hardcover)
At the outset Lightfoot states that this book is intended for the "interested layman." As such it is a decent book with some theory, some data and a good deal of scientific philosophy, or maybe the history of science. However to any reader who may have a backround in such subjects the book seems to be a dangerous gloss of important points. It should also be stated at the outset that Lightfoot is not ashamed to put forth his own ideas on these subjects in which he may, or may not be an expert. At times this tendency is obnoxious, and occasionaly, most often in his chapter conclusions, he states his case honestly and makes it clear that there are some things which he may be mistaken in. As for his final conclusions(the last three chapters) there are a few good points, a paragraph here and there which deomonstrate either Lightfoot's knowledge of his own limitations or at least intelectual honesty. Unfortunately, for the most part these chapters are misleading, rehtorical and uninformed.
