'Over a hundred years ago, the German poet Heine warned the French not to underestimate the power of ideas: philosophical concepts nurtured in the stillness of a professor's study could destroy a civilisation' - Isaiah Berlin, Two Concepts of Liberty, 1958. The nineteen essays collected here show Isaiah Berlin at his most lucid: these short, introductory pieces provide the perfect starting point for the reader new to his work. Their linking theme is the crucial social and political role of ideas, and of their progenitors. The subjects vary widely - from philosophy to education, from Russia to Israel, from Marxism to romanticism - and the appositeness of Heine's warning is exemplified on a broad front. The contents include Berlin's last essay - a retrospective autobiographical survey and the classic statement of his Zionist views. As a whole the book exhibits the full range of his expertise, and demonstrates the enormously engaging individuality, as well as the power, of his own ideas.

As the first academic monograph that a Chinese scholar discusses the histories of thoughts and ideas related to the development of digital economics, this book aims to make research from the perspective of the history of ideas and discuss the ideas influencing the development of digital economics and the evolution of related theories and thoughts with the methodology of interdisciplinary research. The human society is in the stage of major historic transition and enters the digital world with the main goal of developing the artificial world. In this world, the development of digital economics is significantly characterized by the deep interaction between the real and the virtual worlds, while the key triggering this paradigm reform is the evolution of ideas since the modern times. While involving the field of computer, these thoughts are also related to the fields of philosophy, ethics, communication and economics. Therefore, the results of the research on the history of ideas related to digital economics are required to really understand the depth of this discipline. If computationalism is the most important paradigm evolution of natural science, the most important paradigm evolution of social science is interdisciplinary complex science. In the meantime, this book is the most significant in understanding the nature of paradigm evolution related to the development of digital economics from the perspective of complex science and interdisciplinary systematic researches. Digital economics is in the foundation-laying phase, while this book mainly aims to historically narrate the thoughts of this discipline and hopes that readers can understand the influence of ideas in the old era on shaping the disciplines in the new era while exploring this new discipline. The construction of digital economics is a process of evolution. This book will be helpful to understand the underlying logic of the ideas constructed by the thinkers in different fields.

Britain's most authentically prophetic voice - Daily Telegraph 'The choice with which humankind is faced is between the idea of power and the power of ideas.' From his appointment as Chief Rabbi in 1991, through to his death in November 2020, Rabbi Lord Jonathan Sacks made an incalculable contribution not just to the religious life of the Jewish community but to the national conversation - and increasingly to the global community - on issues of ethics and morality. Commemorating the first anniversary of his death, this volume brings together a compelling selection of Jonathan Sacks' BBC Radio Thought for the Day broadcasts, Credo columns from The Times, and a range of articles published in the world's most respected newspapers, along with his House of Lords speeches and keynote lectures. First heard and read in many different contexts, these pieces demonstrate with striking coherence the developing power of Sacks' ideas, on faith and philosophy alike. In each instance he brings to bear deep insights into the immediate situation at the time - and yet it as if we hear him speaking to us afresh, giving us new strength to face the challenges and complexities of today's world. These words of faith and wisdom shine as a beacon of enduring light in an increasingly conflicted cultural climate, and prove the timeless nature and continued relevance of Jonathan Sacks' thought and teachings. One of the great moral thinkers of our time - Robert D. Putnam, author of Bowling Alone
