This is the standard editon of John Locke's classic early work Essays on the Law of Nature. Also included are selected shorter philosophical writings from the 1660s, unpublished elsewhere, whose topics include happiness, pleasure and pain, faith and reason. The great Locke scholar W. von Leyden introduces each of these works, setting them in their historical context. This volume is an invaluable source for Locke's early thought, of interest to philosophers, political theorists, jurists, theologians, and historians.
