A decade prior to his main publications in political philosophy, Kant presented his views on the topic in his 1784 course lectures on natural right. This Critical Guide examines this only surviving student transcript of these lectures, which shows how Kant's political philosophy developed in response to the dominant natural law tradition and other theories. Fourteen new essays explore how Kant's lectures reveal his assessment of natural law, the central value of freedom, the importance of property and contract, the purposes and powers of the state, and the role of individual autonomy and the rights of human beings. The essays place his claims in relation to events and other publications of the early 1780s, and show Kant in the process of working out the theories which would later characterize his influential political philosophy. Essays about Kant's 1784 course lectures on political philosophy, which provide the only early overview of his theory of right. Frederick Rauscher is Professor of Philosophy at Michigan State University. He is the editor and co-translator of Kant's Lectures and Drafts on Political Philosophy (Cambridge, 2016).
