Query: Provocative but for the wrong reasons.

This one is a peculiar mix of populist polemic and third rate scientific argument. Deacon's approach to argument is endless repetition and obfuscation with detail. The initial chapters on indexical,iconic and symolic representation and language acquisition are hardly original and here needlessly complicated. Thick knotted prose, sweeping unsupported statements and carelessly "constructed" arguments abound. It is astounding and intensely disappointing to read the gushing uncritical reviews as well. In short, this book is a menace to critical thinking on this subject.
