To make a long review short, this is an educational piece but not an easy read. If you do not have an extremely good grasp on economics and economic terms, this is not a place to start. Thomas Sowell is a well-read economist and that is easily seen through his book which is full of references and direct quotes from early economic writings. If you are already well versed on economics and are looking for a book that summarizes some of the early thoughts and debates about classical economists, this may be just what you're looking for. If you are still in the early years of your economic knowledge looking to broaden it, you may want to start elsewhere with your classical economics education to avoid confusion due to specific terminology and a lack of explanation surrounding the classical concepts.
