Query: Intellectual Uncleanliness

This book exemplifies what can happen to the scholarship level of an academic area of study when there is no significant internal pier-review or criticism. The author makes unsupported assertion after assertion, creates straw men, makes silly characterizations of the positions of those he disagrees with, makes faulty inferences and draws faulty implications throughout the book. The author claims to have carefully kept his political leanings out of the book. In fact, the entire book is an exercise in moral sophistry through redescription, and one more failed attempt at building a moral metaphysical system. Lakoff's underlying theory (assertion) that our metaphors control our mental conceptualization of the world is finally being critically examined and reviewed.(For a devastating critique, read "Concepts as Metaphors" by Matthew S. McGlone in "Understanding Figurative Language" edited by Sam Gluckberg).
