Melvyn Bragg and guests discuss one of Plato's most striking dialogues, in which he addresses the real nature of power and freedom, and the relationship between pleasure and true self-interest. As he tests these ideas, Plato creates powerful speeches, notably from Callicles who claims that laws of nature trump man-made laws, that might is right, and that rules are made by weak people to constrain the strong in defiance of what is natural and proper. Gorgias is arguably the most personal of all of Plato's dialogues, with its hints of a simmering fury at the system in Athens that put his mentor Socrates to death, and where rhetoric held too much sway over people.

Melvyn Bragg and guests discuss the author and philosopher Iris Murdoch (1919 - 1999). In her lifetime she was most celebrated for her novels such as The Bell and The Black Prince, but these are now sharing the spotlight with her philosophy. Responding to the horrors of the Second World War, she argued that morality was not subjective or a matter of taste, as many of her contemporaries held, but was objective, and good was a fact we could recognize. To tell good from bad, though, we would need to see the world as it really is, not as we want to see it, and her novels are full of characters who are not yet enlightened enough to do that.

Melvyn Bragg and guests discuss the insight into our relationship with the world that Immanuel Kant (1724-1804) shared in his book The Critique of Pure Reason in 1781. It was as revolutionary, in his view, as when the Polish astronomer Copernicus realised that Earth revolves around the Sun rather than the Sun around Earth. Kant's was an insight into how we understand the world around us, arguing that we can never know the world as it is, but only through the structures of our minds which shape that understanding. This idea, that the world depends on us even though we do not create it, has been one of Kant’s greatest contributions to philosophy and influences debates to this day.

Melvyn Bragg and guests discuss the man who, according to Machiavelli, was the last of the Five Good Emperors. Marcus Aurelius, 121 to 180 AD, has long been known as a model of the philosopher king, a Stoic who, while on military campaigns, compiled ideas on how best to live his life, and how best to rule. These ideas became known as his Meditations, and they have been treasured by many as an insight into the mind of a Roman emperor, and an example of how to avoid the corruption of power in turbulent times.

The philosopher Mary Astell (1666 – 1731) has been described as “the first English feminist”. Born in Newcastle in relatively poor circumstances in the aftermath of the upheaval of the English Civil War and the restoration of the monarchy, she moved to London as a young woman and became part of an extraordinary circle of intellectual and aristocratic women. In her pioneering publications, she argued that women’s education should be expanded, that men and women’s minds were the same and that no woman should be forced to marry against her will. Perhaps her most famous quotation is: “If all Men are born Free, why are all Women born Slaves?” Today, she is one of just a handful of female philosophers to be featured in the multi-volume Cambridge History of Political Thought.

Melvyn Bragg and guests discuss the idea that God created the universe and then left it for humans to understand by reason not revelation. Edward Herbert, 1583-1648 (pictured above) held that there were five religious truths: belief in a Supreme Being, the need to worship him, the pursuit of a virtuous life as the best form of worship, repentance, and reward or punishment after death. Others developed these ideas in different ways, yet their opponents in England's established Church collected them under the label of Deists, called Herbert the Father of Deism and attacked them as a movement, and Deist books were burned. Over time, reason and revelation found a new balance in the Church in England, while Voltaire and Thomas Paine explored the ideas further, leading to their re-emergence in the French and American Revolutions.

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.

Melvyn Bragg and guests discuss the French philosopher Henri Bergson (1859-1941) and his ideas about human experience of time passing and how that differs from a scientific measurement of time, set out in his thesis on 'Time and Free Will' in 1889. He became famous in France and abroad for decades, rivalled only by Einstein and, in the years after the Dreyfus Affair, was the first ever Jewish member of the Académie Française. It's thought his work influenced Proust and Woolf, and the Cubists. He died in 1941 from a cold which, reputedly, he caught while queuing to register as a Jew, refusing the Vichy government's offer of exemption.

Melvyn Bragg and guests discuss what it means to be oneself, a question explored by philosophers from Aristotle to the present day, including St Augustine, Kierkegaard, Heidegger and Sartre. In Hamlet, Polonius said 'To thine own self be true', but what is the self, and what does it mean to be true to it, and why should you be true? To Polonius, if you are true to yourself, ‘thou canst not be false to any man’ - but with the rise of the individual, authenticity became a goal in itself, regardless of how that affected others. Is authenticity about creating yourself throughout your life, or fulfilling the potential with which you were born, connecting with your inner child, or something else entirely? What are the risks to society if people value authenticity more than morality - that is, if the two are incompatible?

The image above is of Sartre, aged 8 months, perhaps still connected to his inner child.

Melvyn Bragg and guests discuss the remarkable achievement of Aristotle (384-322BC) in the realm of biological investigation, for which he has been called the originator of the scientific study of life. Known mainly as a philosopher and the tutor for Alexander the Great, who reportedly sent him animal specimens from his conquests, Aristotle examined a wide range of life forms while by the Sea of Marmara and then on the island of Lesbos. Some ideas, such as the the spontaneous generation of flies, did not survive later scrutiny, yet his influence was extraordinary and his work was unequalled until the early modern period.
