This updated edition of a well-established anthology of social and political philosophy combines extensive selections from classical works with significant recent contributions to the field, many of which are not easily available. Its central focus is on the liberal currents in modern Westernpolitical thought--variants of classical liberalism, modern liberalism, and libertarianism--with specific focus on differing conceptions of political obligation, freedom, distributive justice, and representative democracy. The text is organized into four thematic sections: Political Obligation and Consent, Freedom and Coercion, Justice and Equality, and Democracy and Representation, making it easily accessible to students. Each chapter features selections from classical thinkers alongside writings by influentialcontemporary philosophers and political theorists, thus tracing the historical development and transformation of Western political thought on key issues in the field. Among the classical authors represented in this collection are Plato, Hobbes, Locke, Rousseau, and Mill. Contemporary contributorsinclude John Rawls, Isaiah Berlin, Thomas Scanlon, Robert Nozick, Thomas Nagel, Ronald Dworkin, and Hanna Pitkin. Each section is preceded by an introductory overview and followed by a helpful, current bibliography providing guides to further reading.
