This course introduces students to the disciplined study of philosophy through reflection on justice and the grounding and authority of claims invoking justice. The central theme of the course is that conceptions of justice and its authority cannot be understood or established in isolation. The meaning and authority of claims about justice and injustice can only be established through inferential relations to other philosophical issues, for example, concerning reason, knowledge, reality, agency, and identity. These issues will be explored through reflective engagement with classic treatments of these issues by Plato, Hobbes, Kant, and more contemporary philosophical work. The contemporary readings include discussions of distributive justice (concerning access to resources and opportunities); the interplay between gender, race, and conceptions of justice; and whether justice and injustice can be assessed comparatively without reference to a comprehensive, ideal social order.
