In Being in the World: Dialogue and Cosmopolis, noted political theorist Fred Dallmayr explores the world’s transition from a traditional Westphalian system of states to today’s interlocking cosmopolis. Drawing upon biblical literature, as well as ancient philosophers such as Plato and Aristotle and current scholars such as Heidegger, Gadamer, and Raimon Panikkar, this manuscript delves into the importance of what Dallmayr calls “ethical-political engagement.” Dallmayr asserts that traditional concepts of individual and national identity, as well as perceived relationships between the self and others, are undergoing profound change. Every town has become a cosmopolis—an international city—affecting the way that nations conceptualize the relationship between general order and political practice. Rather than lamenting current problems, he suggests ways to successfully address them, through civic education and global citizenship. He argues that what is most needed is a politics of the common good, which requires the cultivation of public ethics, open dialogue, and civic responsibility. The book engages varied philosophical traditions in an original conversation about globalization and our world today.
