First and foremost, this book is a work of genius. A. A. Gill is the funniest man I have every read and his prose strikingly powerful. Woe to Dr. Johnson, for the tide has fully turned! No other outsider but a Scot could have produced such an insightful and vindictive condemnation of the English.
There is a great deal of silliness about Gill, but as he remarks, the best humour is always deeply serious, and it is his underlying seriousness that gives this book such force. One of the great points of pride of the English is their sense of humour, and here Gill finds them at their most revealing. The English trivialization of day to day existence is shown as being a defence mechanism against the heavy psychological repression of their society. Such repression has allowed the English to achieve great things, and has often been characterized by kindness, tolerance, and self-discipline. However, it has come at a very heavy personal cost indeed, and Gill lays out in detail the idiosyncrasies, and anger that lie behind it.
(It was interesting to read the Guardian's review of this book, which immediately trivialized it, by turning it into a joke, without any real discussion of the content. How typical.)
As a Canadian of English descent, living in the French province of Quebec, I have always been intrigued by the deep cultural and social differences that exist between our two founding ethnic groups. Compounding this intrigue is the existence next door of another anglo culture, the Americans. Traits such as overt and complex individualism, social conservatism, anti-intellectualism, and cultural philistinism, have marked North American anglo culture. Gill's book has better helped me better relate these traits to their roots in the UK.
