Margaret Walker's Moral Understandings offers an "expressive-collaborative," culturally situated, practice-based picture of morality, critical of a "theoretical-juridical" picture in most prefeminist moral philosophy since Henry Sidgwick. This essay compares her approach to ethics with that of John Rawls, another exemplar of the "theoretical-juridical" model, and asks how Walker's approach would apply to several ethical issues, including interaction with (other) animals, social reform and revolution, and basic human rights.
