Political theory has traditionally focused on governance within the confines of a specific polity, but with the recent proliferation of environmental realities and national decisions that have global repercussions, political theory must now be re-imagined to confront globalization head-on. Political Theory Without Borders presents a collection scholarship that does just that. Each chapter focuses on answering specific questions that have arisen from issues of global spillover – like climate change and pollution – and the increasingly unrestricted flow of people, products, and financial capital across borders. With contributions from emerging scholars alongside key texts from some of the most well-known theorists of previous generations, this collection illustrates how the classic concerns of political theory – justice and equality, liberty and oppression – have re-emerged with a renewed significance at the global level.
