What is society? Why should citizens obey the law? Is democracy the best form of government? Introducing Political Philosophy expains the central concepts of political thinking through history and presents contexts in which their ideas attracted disciples, controversy and sometimes revolution. How did governments get started? Could we live without them? How much power should they have? What do anarchism, totalitarianism, libertarianism or fascism really mean? In the turmoil of the early 21st century our need for a better grasp of political ideas is greater than ever - Dave Robinson and Judy Groves' concise, enjoyable book is the essential guide.
