In his recent book Natural Law and Practical Rationality, Mark Murphy develops a sophisticated version of a natural law account of practical rationality. I shall show that with only a few minor changes, Murphy's account can be developed into an environmental ethic that generates human obligations to non-human animals, plants, and perhaps even ecosystems and machines. (I shall not discuss here the plausibility of this extension of Murphy's account, relative to competing accounts in environmental ethics; that discussion will have to wait for another occasion.) I begin with a brief sketch of Murphy's account, and then proceed to show how it can be developed into an environmental ethic, with particular attention to several crucial places in the overall argument of his book and arguments developed in other published works.

The story of the show, The Good Place, begins with a common picture of what happens to us after we die. One of the key philosophical issues in the story involves how to assess correctly the moral goodness or badness of a person's life on Earth, since this is the basis of the judgment concerning their eternal destiny. Thomas Nagel claims that there are four kinds of “moral luck”: luck in the circumstances in which we find ourselves, luck with respect to our constitution or character, luck with respect to the results of our actions, and luck with respect to having free choices at all. Perhaps one moral of the story of The Good Place is that life is really complicated, morally speaking—people are not simply good or evil, and cannot be judged easily.
