This final lecture of the course is given "in defense of politics." First, the idea and definition of "politics" and the "political" are discussed with reference to the ideas of Immanuel Kant and twentieth-century political scientists, novelists, and philosophers such as Bernard Crick, E. M. Forster, and Carl Schmitt. Patriotism, nationalism, and cosmopolitanism are also addressed as integral parts of political life. Finally, the role of educators--and "old books"--is discussed as essential to developing a proper understanding of the political.
