I have rarely found so much nonsense compressed between the covers of a book. This a collection of unwarranted, groundless assertions, irresponsible generalizations and shameless one-upmanship. The success of the book in the 60's is proof of the intellectual despair that marked that decade, attempting to get out of the Vietnam Tragedy throug false gurus and other unsubstantiated claims to objectivity. The few pearls are buried under such a mountain of bull that it is not worth the effor to search for them. Mr. McLuhan pretends to know about everything, and shows he knows absout nothing, with the possible exception of English literature. And even there, his judgments are rarely valid and most of the time intellectually irresponsible. This is not a serious book. Future generations will look at it and judge our enthusiasm for it as proof of our immaturity. I gave it one star because I could not give it zero.
