In this first book-length comparative study of these leading eighteenth-century thinkers, Dennis Rasmussen highlights Smith’s sympathy with Rousseau’s concerns and analyzes in depth the ways in which Smith crafted his arguments to defend commercial society against these charges. These arguments, Rasmussen emphasizes, were pragmatic in nature, not ideological: it was Smith’s view that, all things considered, commercial society offered more benefits than the alternatives. Just because of this pragmatic orientation, Smith’s approach can be useful to us in assessing the pros and cons of commercial society today and thus contributes to a debate that is too much dominated by both dogmatic critics and doctrinaire champions of our modern commercial society.
