Melvyn Bragg and guests discuss the ideas of Jean-Jacques Rousseau (1712-1778) on the education of children, as set out in his novel or treatise Emile, published in 1762. He held that children are born with natural goodness, which he sought to protect as they developed, allowing each to form their own conclusions from experience, avoiding the domineering influence of others. In particular, he was keen to stop infants forming the view that human relations were based on domination and subordination. Rousseau viewed Emile as his most imporant work, and it became very influential. It was also banned and burned, and Rousseau was attacked for not following these principles with his own children, who he abandoned, and for proposing a subordinate role for women in this scheme. The image above is of Emile playing with a mask on his mother's lap, from a Milanese edition published in 1805.

Melvyn Bragg and guests discuss the work and ideas of Dorothy Crowfoot Hodgkin (1910-1994), awarded the Nobel Prize in Chemistry in 1964 for revealing the structures of vitamin B12 and penicillin and who later determined the structure of insulin. She was one of the pioneers of X-ray crystallography and described by a colleague as 'a crystallographers' crystallographer'. She remains the only British woman to have won a Nobel in science, yet rejected the idea that she was a role model for other women, or that her career was held back because she was a woman. She was also the first woman since Florence Nightingale to receive the Order of Merit, and was given the Lenin Peace Prize in recognition of her efforts to bring together scientists from the East and West in pursuit of nuclear disarmament.

Melvyn Bragg and guests discuss the ideas developed by the Anglican priest John Nelson Darby (1800-1882), drawn from his reading of scripture, in which Jesus would suddenly take His believers up into the air, and those left behind would suffer on Earth until He returned with His church to rule for a thousand years before Final Judgement. Some believers would look for signs that civilization was declining, such as wars and natural disasters, or for new Roman Empires that would harbour the Antichrist, and from these predict the time of the Rapture. Darby helped establish the Plymouth Brethren, and later his ideas were picked up in the Scofield Reference Bible (1909) and soon became influential, particularly in the USA. With Elizabeth Phillips Research Fellow at the Margaret Beaufort Institute at the University of Cambridge and Honorary Fellow in the Department of Theology and Religion at Durham University Crawford Gribben Professor of Early Modern British History at Queen’s University Belfast and Nicholas Guyatt Reader in North American History at the University of Cambridge Producer: Simon Tillotson

Melvyn Bragg and guests discuss how, in September 1812, Napoleon captured Moscow and waited a month for the Russians to meet him, to surrender and why, to his dismay, no-one came. Soon his triumph was revealed as a great defeat; winter was coming, supplies were low; he ordered his Grande Armée of six hundred thousand to retreat and, by the time he crossed back over the border, desertion, disease, capture, Cossacks and cold had reduced that to twenty thousand. Napoleon had shown his weakness; his Prussian allies changed sides and, within eighteen months they, the Russians and Austrians had captured Paris and the Emperor was exiled to Elba.

In the 500th edition of the programme, Melvyn Bragg and his guests discuss the philosophical idea of free will. Free will - the extent to which we are free to choose our own actions - is one of the most absorbing philosophical problems, debated by almost every great thinker of the last two thousand years. In a universe apparently governed by physical laws, is it possible for individuals to be responsible for their own actions? Or are our lives simply proceeding along preordained paths? Determinism - the doctrine that every event is the inevitable consequence of what goes before - seems to suggest so. Many intellectuals have concluded that free will is logically impossible. The philosopher Baruch Spinoza regarded it as a delusion. Albert Einstein wrote: "Human beings, in their thinking, feeling and acting are not free agents but are as causally bound as the stars in their motion." But in the Enlightenment, philosophers including David Hume found ways in which free will and determinism could be reconciled. Recent scientific developments mean that this debate remains as lively today as it was in the ancient world.
