If you wish to have a good summary of certain aspects (i.e., the interactions and relations between liberty, wealth and equality) of three great thinkers (Montesquieu, Adam Smith, Tocqueville; Ernst Gellner is also treated but not to much in depth, really), this book is interesting. But not at all enough to cope with its ambitious aims: i) to explain the obstacles which had halted the growth of all great agrarian civilizations up to the18th century ; and ii) to try and explain what has happened since the 18th century. By the end of the book, the author recognizes that "there is still a large gap in the explanation of how the transition to the modern world has occurred" and that there is still pending an explanation of the technological and scientific growth in western Europe between the 12th-19th centuries and why, during the same period, it slowed down, ceased and even partially regressed in other civilizations which had previously been far more advanced than Europe. As of today, nobody has a definitive answer to this, but I would suggest to read the following books: "The Rise of the West" by William H. McNeill, "World History. A new perspective" by Clive Ponting, "Reorient" by Andre Gunder Frank, "The Great Divergence", by Kenneth Pomeranz, "The Dynamics of Global Dominance. European Overseas Empires 1415-1980", by David Abernethy and "The Cash Nexus" by Niall Ferguson.
