This book offers an account of ten crucial moments in the history of ideas, which represent ten key moments of the discovery of pluralism. From the Indian emperor Ashoka to Origen and from Nicola Cusano to Las Casas, Montaigne, Lessing, giants who opened the way to the thought of tolerance, challenging the dogma of a unique truth dictated by authority, followed in this reconstruction by other glowing thinkers of the twentieth century, such as Horace Kallen, Margaret Mead, and Jacques Dupuis. These protagonists, each in their own way, battled against monism for the respect of differences and for the knowledge of otherness. This kind of hall of fame of pluralist thinkers ends with the most important figure of the pluralism of values, Isaiah Berlin, of whom an unpublished interview appears here for the first time in English. The volume is unique in this two-thousand-year-old variety of voices gathered under the denominator of cultural pluralism that they embody in the deepest and most challenging sense, often at the limits and beyond the limits of heresy. It is of great value and interest to scholars and students of theoretical, moral, political philosophy, sociology, comparative studies, comparative literature, religious diversity, religious studies, anthropology, and all those interested in the history of tolerance. 

In The Lesson of this Century Popper's purpose is to warn us against the increasing violence and egoism of our society. What solutions can we offer to the problems of the environment, demography and corruption? How can we prevent the violence our society engenders? How can we preserve our democratic system while at the same time paving the way for global peace? Popper believes that the philosopher has a duty to intervene in politics and he utters a clear call to all of us to recognise our responsibilities. He reminds us that it is our actions which will create the world of tomorrow.
The interviews in this volume were originally given to the Italian journalist Giancarlo Bosetti. The volume also includes the transcript of an interview about the moral dangers of television not previously available in English.
