The historian Niall Ferguson examines institutions outside the political, economic and legal realms, whose primary purpose is to preserve and transmit particular knowledge and values. In a lecture delivered at the Royal Society of Edinburgh, he asks if the modern state is quietly killing civil society in the Western world? And what can non-Western societies do to build a vibrant civil society?

The historian Niall Ferguson delivers a lecture at Gresham College in the heart of legal London, addressing the relationship between the nature of law and economic success.

The eminent economic historian Niall Ferguson travels to the world's financial centre to deliver a lecture at the New-York Historical Society. He reflects on the causes of the global financial crisis, and argues that many people have drawn erroneous conclusions from it about the role of regulation. Is regulation, he asks, in fact "the disease of which it purports to be the cure"?

The eminent economic historian Professor Niall Ferguson argues that institutions determine the success or failure of nations. In a lecture delivered at the London School of Economics and Political Science, he says that a society governed by abstract, impersonal rules will become richer than one ruled by personal relationships. The rule of law is crucial to the creation of a modern economy and its early adoption is the reason why Western nations grew so powerful in the modern age.

But are the institutions of the West now degenerating? Professor Ferguson asks whether the democratic system has a fatal flaw at its heart. In the West young people are confronting the fact that they must live with the huge financial debt generated by their parents, something they had no control over despite the fact that they were born into a democracy. Is there a way of restoring the compact between different generations?

THE REITH LECTURES 2010

In the last Reith Lecture of 2010, Martin Rees, President of the Royal Society and Astronomer Royal, explores how fast our world is moving in the 21st century. Speaking at the Open University in Milton Keynes, the home of online learning, he acknowledges how the internet and other technologies have transformed our lives. Now he calls on politicians and other authorities to provide the funding that will keep the UK among the world's front runners in scientific research and discovery. Without money and without education to attract young people into science, the UK is in danger of falling behind China and other countries in the Far East that are investing heavily in their science and technology sectors. Professor Rees ends his series of lectures evoking memories of the 'glorious' Ely Cathedral, near Cambridge, a monument built to last a thousand years. If we, like the cathedral builders, redirect our energies and focus on the long-term, he believes together we can solve the problems that face our planet, and secure its future for billions of people worldwide and for generations to come.
