I have always felt uneasy with this book since I was an under graduated student, 30 years ago. This is undoubtedly a quiet useful book for anyone who needs a bird's-eye view of the classics in economics. If you don't have time to read Smith's Wealth of Nations or Marshall's Principles, here you have the book you need. However, it is not here that you can look for a good analysis of the meaning and implications of the main schools of economic thought, as well as the relevance of the work of its most distinguished authors and their social and intellectual environment. That is reason why I always preferred Schumpeter's History of Economic Analysis. Today, that I am lecturing this course my dissatisfaction has increased, among other reasons because you have more and better textbooks, such as Lionel Robbins' History of Economic Thought, Mark Skoussen's Making of Modern Economics, or Jürg Niehams' History of Economic Theory, which I really enjoyed reading because they try to make a portrayal of the intellectual and human stature of the most important economists of all times and their background.
