Presents an iconoclastic account of morality and moral discourse from the perspective of Daoist philosophy. Drawing on both western and Chinese philosophy, Those Who Act Ruin It shows how Daoism presents a viable alternative to established moral theories. The Daoist, critical of the Confucian and Mohist discourses of their time, provides an account of morality that can best be understood as achieving an attunement to situations through the cultivation of habits. Furthermore, Daoism's meta-ethical insights outline how moral philosophy, when theorized in a way that ignores our fundamental interdependence, devolves into moralistic narcissism. Another way of putting this, as the Daodejing states perfectly, is that "those who act ruin it" (). Sensitive to this problem, the Daoist account of moral attunement can ameliorate social woes and not "ruin things." In their moral attunement, Daoists can spontaneously respond to situations in ways that are sensitive to the underlying interdependence of all things.
