This book is perhaps the most stunning available demonstration of the explanatory power of the parametric approach to linguistic theory. It is akin, not to a deductive proof, but to the discovery of a footprint in a far-off place which leaves an archeologist elated. The book is full of intricate reasoning, but the stunning aspect is that the reasoning moves between not only complex syntax and diverse languages, but it makes predictions about what two-year-old children will assume about the jumble of linguistic input that confronts them. Those predictions, Hyams shows, are supported by a...
