The ninth edition of the famous and popular satire on the true causes of social welfare and riches, in which Mandeville suggests that base behavior produces positive economic effects. The theory of the origin of society so prominent in Part I was widely criticized after the publication of the 1723 edition. In the second volume, probably in response to his critics, Mandeville moved towards a more evolutionary account of society. The work had a clear influence on the thinking of Adam Smith and David Hume.
