In Our Time

Jupiter is the largest planet in our solar system, and it’s hard to imagine a world more alien and different from Earth. It’s known as a Gas Giant, and its diameter is eleven times the size of Earth’s: our planet would fit inside it one thousand three hundred times. But its mass is only three hundred and twenty times greater, suggesting that although Jupiter is much bigger than Earth, the stuff it’s made of is much, much lighter. When you look at it through a powerful telescope you see a mass of colourful bands and stripes: these are the tops of ferocious weather systems that tear around the planet, including the great Red Spot, probably the longest-lasting storm in the solar system. Jupiter is so enormous that it’s thought to have played an essential role in the distribution of matter as the solar system formed – and it plays an important role in hoovering up astral debris that might otherwise rain down on Earth. It’s almost a mini solar system in its own right, with 95 moons orbiting around it. At least two of these are places life might possibly be found.

In 1956 Oxford University awarded an honorary degree to the former US president Harry S. Truman for his role in ending the Second World War. One philosopher, Elizabeth Anscombe (1919 – 2001), objected strongly.

She argued that although dropping nuclear bombs on Hiroshima and Nagasaki may have ended the fighting, it amounted to the murder of tens of thousands of innocent civilians. It was therefore an irredeemably immoral act. And there was something fundamentally wrong with a moral philosophy that didn’t see that.

This was the starting point for a body of work that changed the terms in which philosophers discussed moral and ethical questions in the second half of the twentieth century.

A leading student of the philosopher Ludwig Wittgenstein, Anscombe combined his insights with rejuvenated interpretations of Aristotle and Thomas Aquinas that made these ancient figures speak to modern issues and concerns. Anscombe was also instrumental in making action, and the question of what it means to intend to do something, a leading area of philosophical work.

Sophocles’ play Oedipus Rex begins with a warning: the murderer of the old king of Thebes, Laius, has never been identified or caught, and he’s still at large in the city. Oedipus is the current king of Thebes, and he sets out to solve the crime.

His investigations lead to a devastating conclusion. Not only is Oedipus himself the killer, but Laius was his father, and Laius’ wife Jocasta, who Oedipus has married, is his mother.

Oedipus Rex was composed during the golden age of Athens, in the 5th century BC. Sophocles probably wrote it to explore the dynamics of power in an undemocratic society. It has unsettled audiences from the very start: it is the only one of Sophocles’ plays that didn’t win first prize at Athens’ annual drama festival. But it’s had exceptionally good write-ups from the critics:

Melvyn Bragg and guests discuss the power-packs within cells in all complex life on Earth.

Inside each cell of every complex organism there are structures known as mitochondria. The 19th century scientists who first observed them thought they were bacteria which had somehow invaded the cells they were studying. We now understand that mitochondria take components from the food we eat and convert them into energy.

Mitochondria are essential for complex life, but as the components that run our metabolisms they can also be responsible for a range of diseases – and they probably play a role in how we age. The DNA in mitochondria is only passed down the maternal line. This means it can be used to trace population movements deep into human history, even back to an ancestor we all share: mitochondrial Eve.

In 1661 the 23 year-old French king Louis the XIV had been on the throne for 18 years when his chief minister, Cardinal Mazarin, died. Louis is reported to have said to his ministers, “It is now time that I govern my affairs myself. You will assist me with your counsels when I ask for them [but] I order you to seal no orders except by my command… I order you not to sign anything, not even a passport, without my command, and to render account to me personally each day”

So began the personal rule of Louis XIV, which lasted a further 54 years until his death in 1715. From his newly-built palace at Versailles, Louis was able to project an image of himself as the centre of gravity around which all of France revolved: it’s no accident that he became known as the Sun King. He centralized power to the extent he was able to say ‘L’etat c’est moi’: I am the state. Under his rule France became the leading diplomatic, military and cultural power in Europe.

In the year 29 BC the great Roman poet Virgil published these lines:

They’re from his poem the Georgics, a detailed account of farming life in the Italy of the time. ‘Georgics’ means ‘agricultural things’, and it’s often been read as a farming manual. But it was written at a moment when the Roman world was emerging from a period of civil war, and questions of land ownership and management were heavily contested. It’s also a philosophical reflection on humanity’s relationship with the natural world, the ravages of time, and the politics of Virgil’s day.

It’s exerted a profound influence on European writing about agriculture and rural life, and has much to offer environmental thinking today.

Melvyn Bragg and guests discuss the Christian uprising in Japan and its profound and long-term consequences.

In the 1630s, Japan was ruled by the Tokagawa Shoguns, a military dynasty who, 30 years earlier, had unified the country, ending around two centuries of civil war. In 1637 a rebellion broke out in the province of Shimabara, in the south of the country. It was a peasants’ revolt, following years of bad harvests in which the local lord had refused to lower taxes. Many of the rebels were Christians, and they fought under a Christian banner.

The central government’s response was merciless. They met the rebels with an army of 150 000 men, possibly the largest force assembled anywhere in the world during the Early Modern period. Once the rebellion had been suppressed, the Shogun enforced a ban on Christianity and expelled nearly all foreigners from the country. Japan remained more or less completely sealed off from the rest of the world for the next 250 years.

Melvyn Bragg and guests discuss the revelatory collection of Biblical texts, legal documents, community rules and literary writings.

In 1946 a Bedouin shepherd boy was looking for a goat he’d lost in the hills above the Dead Sea. He threw a rock into a cave and heard a hollow sound. He’d hit a ceramic jar containing an ancient manuscript. This was the first of the Dead Sea Scrolls, a collection of about a thousand texts dating from around 250 BC to AD 68. It is the most substantial first hand evidence we have for the beliefs and practices of Judaism in and around the lifetime of Jesus.

The Dead Sea Scrolls have transformed our understanding of how the texts that make up the Hebrew Bible were edited and collected. They also offer a tantalising window onto the world from which Christianity eventually emerged.

Melvyn Bragg and guests discuss the highly influential American poet Walt Whitman.

In 1855 Whitman was working as a printer, journalist and property developer when he published his first collection of poetry. It began:

I celebrate myself,

The book was called Leaves of Grass. In it, Whitman set out to break away from European literary forms and traditions. Using long lines written in free verse, he developed a poetry meant to express a distinctively American outlook.

Leaves of Grass is full of verse that celebrates both the sovereign individual, and the deep fellowship between individuals. Its optimism about the American experience was challenged by the Civil War and its aftermath, but Whitman emerged as a celebrity and a key figure in the development of American culture.
