The long republican tradition is characterized by a conception of freedom as non‐domination, which offers an alternative, both to the negative view of freedom as non‐interference and to the positive view of freedom as self‐mastery. The first part of the book traces the rise and decline of the conception, displays its many attractions and makes a case for why it should still be regarded as a central political ideal. The second part of the book looks at the sorts of political and civil institutions that would be required in a society in which freedom as non‐domination is systematically fostered. It outlines the causes and policies, the constitutional and democratic forms, and the regulatory controls that a republican state ought to endorse. And it argues for a vision of the state's relation to civil society in which there is no pretence of doing without widespread civility and trust; the argument is that the state ought, at once, to foster and build on such extra‐political foundations
