Here’s my colleague Dan Klein on Adam Smith’s attitude toward Rousseau. I do especially love the opening quotation from David Hume:
Thus you see, he is a Composition of Whim, Affectation, Wickedness, Vanity, and Inquietude, with a very small, if any Ingredient of Madness. … The ruling Qualities abovementioned, together with Ingratitude, Ferocity, and Lying, I need not mention, Eloquence and Invention, form the whole of the Composition.
