Liberty and Nature: An Aristotelian Defense of Liberal Order is a 1991 political philosophy book by the philosophers Douglas B. Rasmussen and Douglas Den Uyl. Tom G. Palmer writes that Rasmussen and Den Uyl, who are influenced by Aristotle's Nicomachean Ethics, defend a version of "moral realism" and explore "the idea that rights are a requirement of the life of a living reasoning entity."
