This collection of Pierce's essays traces the evolution of her thinking about natural law theory--and, more broadly, about talk of "natures" as normatively significant--over a period of 30 years. We see her move from a wholesale rejection of such talk, in her influential 1971 piece "Natural Law Language and Women," to a qualified admission that it can have its liberatory uses. Yet she maintains throughout that, progressive potential or no, natural law is far inferior to Kantian notions of rights and autonomy as a foundation for ethical thought.
