Synthesized answer
The book "The Sources of Normativity" by Christine M. Korsgaard explores the authority of ethical concepts [Passage 1]. Ethical concepts are described as normative because they make claims on us, such as commanding, obliging, recommending, or guiding [Passage 1]. Alternatively, when we use these concepts, we make claims on one another [Passage 1].
Korsgaard identifies four accounts of where this normativity originates: voluntarism, realism, reflective endorsement, and the appeal to autonomy [Passage 1]. The book traces the history of these accounts, showing how each evolved from the one preceding it, and compares their historical and contemporary forms [Passage 1]. Kant's theory, which posits that normativity arises from our own autonomy, is presented as a combination of the other three accounts [Passage 2]. The passages do not provide further details on how Korsgaard explains these key concepts in her own words beyond this framework.
