A reminder from Amnesty International of the power of free speech in the face of oppression--and of the fact that "ordinary people, not just journalists, novelists, and poets . . . can be saved by international opinion.'' In this collection of addresses delivered at Oxford University, six novelists speak to aspects of political dissent. Just when these speeches were delivered is unclear; Andr‚ Brink's penetrating remarks on the apartheid regime of his native South Africa, for example, suggest that he spoke well before the election of Nelson Mandela.
