 Another example follows the work of Adam Smith, claiming that libertarian ideas are inherent in our ordinary moral psychology. Smith famously considered justice to be strictly negative in nature: something we satisfy simply through abstaining from theft, coercion, and other violations of libertarian rights. Thus, in The Theory of Moral Sentiments, Smith wrote that the rules that “call loudest for vengeance and punishment are the laws which guard the life and person of our neighbour; the next are those which guard his property and possessions; and last of all come those which guard what are called his personal rights, or what is due to him from the promises of others” (Smith 1759 [1976], p. 84). These are the only acts that are generally disapproved of in a way calling for punishment (1759 [1976], p. 78). Human rule following of this kind is desirable because it’s conducive to the stability and effectiveness of society (1976 [1759], p. 86).
