I'll admit, that I didn't finish it. I got to the part where he starts going on and on about the proper price of things and the relationship to the price of gold, and "the torpor of my mind rendered me not only incapable of relishing or bearing a part in any rational conversation, but of conceiving any generous, noble, or tender sentiment, and consequently of forming any just judgement concerning many even of the ordinary duties of private life." WoN is a LONG book!
But I did get past that paragraph, and it seems to have flown out the other ear.
I encourage you to read it. Pick up a copy (or get one of the many electronic versions), and go through it a bit at a time.
The book is well organised, though Smith is Very Wordy. Realise that he's building an argument, based on a great deal of observations, conversation, correspondece, lectures, and study. He's not a perfect guide, but he's a good and early one.
He's also been tremendously mis-cast by a great many others, and reading Smith in his own words is very often an antidote to that.
I'm working my way through various economic works, in a bit of a hop-scotch. There are a few good histories of thought -- The Worldly Philosophers, by Heilbronner, was popular in my uni days (1980s). Backhouse's The Ordinary Business of Life is more comprehensive, though exceedingly dry.
I found Arnold Toynbee (the elder), Lectures on the Industrial Revolution, to be fascinating. I'm going through a bit of John Stuart Mill (both he and his father wrote economics texts), and want to work through Marshall and Keynes. I have a sense that the state of economic theory around the turn of / early 20th century was important.
For more recent theory -- I'm pretty disappointed in economics (it was my major field of study) -- but suggest a mainstream textbook as at least an anchor. Steve Keen, Herman Daly, Nicholaus Georgescu-Roegen, W. Brian Arthur, and the chap at Oxford University I can't think of right now (Eric? Nick?) are interesting. Ah: Erick Beinhocker.
