This year's Reith Lecturer is British historian Arnold J Toynbee. The former Director of Studies at the Royal Institute of International Affairs, he is currently the Koraes Professor of History at London University. He considers how Europe interacts with other countries in his Reith Lecture series entitled 'The World and the West'.

In his fifth lecture entitled 'The Psychology of Encounters', Professor Toynbee examines ways in which countries respond to new cultures. He argues that the most important differences are invariably rejected, but that minor "culture strands" are often allowed to flourish, thus creating a patchwork of cultural identities.

This year's Reith Lecturer is British lawyer Lord Radcliffe. He was Director-General of the Ministry of Information during the Second World War, and is most famous for his role in Partition, the division of the British Indian Empire, His work led directly to the creation of Pakistan and India as independent nations. He examines the features of democratic society, and considers the problematic notions of power and authority in his series of seven Reith Lectures entitled 'Power and the State'.

The inaugural Reith Lecturer is the philosopher, mathematician, and social reformer Bertrand Russell. One of the founders of analytic philosophy and a Nobel Laureate, he is the author of Principia Mathematica, and the bestselling History of Western Philosophy, written in 1946. His Reith lecture series is entitled 'Authority and the Individual'.

In his final lecture, entitled 'Individual and Social Ethics', he relates social and political doctrines to the individual ethics by which people guide their personal lives. He argues that Man needs a sense of personal morality to guide his conduct, and must learn to be critical of tribal customs and beliefs that may be generally accepted amongst his neighbours. Primitive impulses, he says, can find harmless outlets in adventure and creation. He suggests that Man has always been subject to two miseries: firstly, those imposed by external nature which are now largely diminished by science; and secondly, those that men inflict on each other, such as through war. Russell rejects the argument that human nature demands war, believing instead that the greed for possession will lessen as the fear of destitution is removed from society.

In his penultimate Reith lecture, entitled 'Control and Initiative: Their Respective Spheres', Bertrand Russell considers which matters should be controlled by the state in a healthy and progressive society, and what should be left to private initiative. He argues that in our complex world, there cannot be fruitful initiative without government, but nor can there be government without initiative.

In his fourth lecture, entitled 'The Conflict of Technique and Human Nature', he examines what part human nature has played in the development of civilised society, and argues that poverty, suffering and cruelty are no longer necessary to the existence of civilisation. He believes these can be eliminated with the help of modern science, provided it operates in a humane spirit, and with an understanding of the springs of happiness and life.
