Abstract
In this book review essay, Justus discusses Human Language and Our Reptilian Brain: The Subcortical Bases of Speech, Syntax, and Thought (2000) by Philip Lieberman. While the review agrees that a variety of cortical and subcortical regions (such as the basal ganglia) contribute to language, it also suggests that the book has confounded questions of brain localization with developmental constraint, domain specificity, and evolutionary adaptation, drawing upon works by Chomsky (1975), Fodor (1983), Pinker (1994), Bloom (2000), and Calvin and Bickerton (2000).
