The Wealth of Nations was a challenge to get through. Although I only had to read the first nine chapters (about 78 pages), it took me about four weeks to finish. Economics is really not my strong suit and it took extra effort to comprehend Smith's words and, now that I'm done, I feel like nearly everything I read has already slipped from my memory.
Consequently, I don't have much to say on this one. I enjoyed the parts when Smith drew on historical examples to prove his points, because of my interest in history, but I found The Wealth of Nations very dry reading overall.
I also think I'm getting Enlightenment fatigue. The last few authors on the Great Books reading list (Locke, Rousseau, Thomas Jefferson, the Federalist authors, and Smith) have all been Enlightenment thinkers and I'm beginning to crave a change of scenery.
