I'm ashamed to see how few reviews I've done of Chomsky's books. His deadpan presentation of the evidence has profoundly influenced the way I see the world since I was in my early 20s.
His method is simple. He doesn't construct a big conspiracy theory based on shreds of evidence. He starts from the standpoint that the political processes that we really need to scrutinise are the ones we have a chance of influencing - i.e., our own. From here, he looks at what our politicians say they are doing, and compares this with what they are verifiably reported as doing, and also with what the mainstream media says they are doing. None of this is any more than the scientific method as applied to media studies.
From this method, he draws down devastatingly critical results, in which politicans are condemned by the facts that their own organisations have elicited. Chomsky can ruin your faith in your elected leaders like nobody else. However, he is animated by a vision of freedom and justice that is truly democratic and egalitarian - and he is not blind to the fact that there are people out there who don't believe in freedom or justice but in theocracy. He just wants to point out that some of those people form the backbone of the US government.
This is a selection of op-ed columns, hardly the kind of book-length closely reasoned argument that any Chomsky-experienced radical will be looking for, but a bracing shot in the arm for anyone who just feels bewildered and confused by the whole situation and wants someone to suggest a direction towards clarity. Chomsky is by nature not a guru, positively allergic to 'followers' - merely someone with more access to information than most of us, and so disinclined to tell people what to do. But this little book is a small light that may help to illuminate the road towards an exit from the confusion and impotence that paralyse us every day.
