In Our Time Folgen

Melvyn Bragg discusses the discovery of Oxygen by Joseph Priestley and Antoine Lavoisier. In the late 18th century Chemistry was the prince of the sciences – vital to the economy, it shaped how Europeans fought each other, ate with each other, what they built and the medicine they took. And then, in 1772, the British chemist, Joseph Priestley, stood in front of the Royal Society and reported on his latest discovery: “this air is of exalted nature…A candle burned in this air with an amazing strength of flame; and a bit of red hot wood crackled and burned with a prodigious rapidity. But to complete the proof of the superior quality of this air, I introduced a mouse into it; and in a quantity in which, had it been common air, it would have died in about a quarter of an hour; it lived at two different times, a whole hour, and was taken out quite vigorous.” For the British dissenting preacher, Joseph Priestley, and the French aristocrat, Antoine Lavoisier, Chemistry was full of possibilities and they pursued them for scientific and political ends. But they came to blows over oxygen because they both claimed to have discovered it, provoking a scientific controversy that rattled through the laboratories of France and England until well after their deaths. To understand their disagreement is to understand something about the nature of scientific discovery itself.

Melvyn Bragg and guests discuss the Persian Islamic philosopher, Avicenna. In the city of Hamadan in Iran, right in the centre, there is a vast mausoleum dedicated to an Iranian national hero. Built in 1952, exactly 915 years after his death, it’s a great conical tower with twelve supporting columns. It’s dedicated not to a warrior or a king but to a philosopher and physician. His name is Ali Al Husayn Ibn-Sina, but he is also known as Avicenna and he is arguably the most important philosopher in the history of Islam.  In a colourful career Avicenna proved the existence of god, amalgamated all known medical knowledge into one big book and established a mind body dualism 600 years before Descartes and still found time to overindulge in wine and sex.

Melvyn Bragg and guests discuss morality by taking a long hard look at the idea of guilt. The 18th century politician and philosopher Edmund Burke was once moved to comment: “Guilt was never a rational thing; it distorts all the faculties of the human mind, it perverts them, it leaves a man no longer in the free use of his reason, it puts him into confusion.”Guilt is a legal category but also a psychological state and a moral idea. Over the centuries theologians, philosophers and psychologists have tried to determine how it relates to morality, reason and the workings of the mind? The answers seem to cut deeply into our understanding of what it is to be human.With Stephen Mulhall, Fellow and Tutor in Philosophy at New College, Oxford; Miranda Fricker, Senior Lecturer in Philosophy at Birkbeck, University of London; Oliver Davies, Professor of Christian Doctrine at King’s College London
