In this Essay on Professor Oman’s beautifully written and meticulously researched book, The Dignity of Commerce, I do three things. First, I describe what I take to be the central message of the book, namely, that markets promote liberal values of tolerance, pluralism, and cooperation among rival, even hostile groups. Second, I show how Oman’s argument draws from a line of political and economic thought that dates to the Enlightenment, the so-called doux commerce thesis of thinkers like Montesquieu and Adam Smith. Finally, I discuss what I consider the most penetrating criticism of that thesis, Edmund Burke’s critique from tradition, which suggests we should be careful attributing too much to markets’ ability to promote liberal pluralism. According to Burke, it is the Western tradition, not commerce, which creates the tolerant, pluralist marketplace of the doux commerce thesis. That Burke was correct is suggested by several historical examples and by contemporary events in the United States and across the globe. That is not to say that Oman is entirely wrong about the potential political benefits of the market, only that we should be careful not to overstate them.
