I read the first 10 chapters of Wealth of Nations for a history of economic thought class. He was suprisingly easy to read. He seemed to be sincerely concerned about the welfare of the working class. And he seemed to be able to separate his view on how society should be from how it actually is, and effectively write about the latter. His political views seemed to be pragmatic rather than dogmatic (compared to some of the people that cite him today), which I like.
