In this groundbreaking work, Ellen Meiksins Wood lays out her innovative approach to the history of political theory and traces the development of the Western tradition from classical antiquity through the late Middle Ages. Her social history is a significant departure from other contextual interpretations. Treating canonical thinkers as passionately engaged human beings, Wood examines their ideas not simply in the context of political discourse but as creative responses to the social relations and conflicts of their time and place. From the Ancient Greek polis of Plato and Aristotle, through the Roman Republic of Cicero and the Empire of St. Paul and St. Augustine, to the medieval world of Averroes, Thomas Aquinas and William of Ockham, Citizens to Lords offers a rich, dynamic exploration of thinkers and ideas that have stamped their imprint upon history and the present day.
