Dan Klein, of George Mason University, talks with EconTalk host
Russ Roberts about Adam Smith's lesser-known masterpiece,

The Wealth of Nations, Smith's willingness to accept "vague, loose, and indeterminate" rules rather than precise ones, Smith's criteria for assessing what is moral and what is not, and Smith's conception of justice.
