All too often introductions to political theory and ideology are dry, lacking in contemporary resonance, and seem to assume that ideas are detached from political practice. This book aims to show that political ideas, theories, ideologies 'live', in two senses -- ordinary people live their consequences, and they change and adapt with the rhythms of political life. It explores in depth selected key political ideas, interrogating them through historical and conceptual analysis, and a range of case materials. Chapters cover political legitimacy, nationalism and national self-determination, dissent and ideology, and social justice. There is also an extended reflection on the ideas of 'theory' and 'ideology' themselves. The emphasis throughout is on accessibility to readers who are new to the subject.
