This book is not for those who may have difficulty navigating the academic discourse of post-modern linguistic philosophy. But if one has an ear for the dialect, the author's development of the implications of a latter-Wittgensteinian approach to meaning is, I believe, unparalleled, refreshing, and imaginatively insightful. Rather than interpreting the subject from within (ultimately leading to philosophical implosion), the trajectory is drawn with an attack on the representational theory of mind, through the work of the Russian psychologist L.S. Vygotsky, into nebulous conclusions that may well beneficially impact education, social theory, and the cognitive sciences in general. If you can hack the academics, it's the best book on the subject I've seen.
