In Utopia, Thomas More gives us a traveller’s account of a newly-discovered island where the inhabitants enjoy a social order based on natural reason and justice, and human fulfilment is open to all. As the traveller describes the island, a bitter contrast is drawn between this rational society and the practices of Europe. How can the philosopher reform his society? In his discussion, More takes up a question first raised by Plato and which is still a challenge in the contemporary world. In the history of political thought few works have been more influential than Utopia, and few more misunderstood.
