 With respect to the specific content of natural law, Locke never provides a comprehensive statement of what it requires. In the Two Treatises, Locke frequently states that the fundamental law of nature is that as much as possible mankind is to be preserved. Simmons (1992) argues that in Two Treatises 2.6 Locke presents (1) a duty to preserve one’s self, (2) a duty to preserve others when self-preservation does not conflict, (3) a duty not to take away the life of another, and (4) a duty not to act in a way that “tends to destroy” others. Libertarian interpreters of Locke tend to downplay duties of type 1 and 2. Locke presents a more extensive list in his earlier, and unpublished in his lifetime, Essays on the Law of Nature. Interestingly, Locke here includes praise and honor of the deity as required by natural law as well as what we might call good character qualities.
