When we think of nationalism, we tend to think of its extreme varieties. In fact, it's so ubiquitous in our daily lives that we rarely even notice it, says political theorist and former Israeli politician Yael Tamir. Here, she recommends books to help us better understand nationalism in all its forms and why one ignores its power at one's peril.

Convenient as it is to blame our political woes on the polarizing effect of social media, echo chambers, interference by foreign powers or other shadowy operators, the truth is that human nature and our search for identity and status are more likely culprits. Sociologist Chris Bail, a professor at Duke University and director of its 'Polarization Lab', talks us through what social science has to say about the connection between social media and political polarization.

Johann Wolfgang von Goethe (1749–1832) has been described as ‘the last true polymath to walk the earth’. A defining figure in German literature, Goethe coined the concept of world literature. And his literary and dramatic achievements are matched by his scientific work. David E. Wellbery, Professor of Germanic Studies at the University of Chicago and recipient of the Golden Goethe Medal, introduces us to the life and work of Goethe. He explores why figures such as Beethoven and Napoleon were magnetised to him, how Rousseau influenced Faust, and why Goethe’s Faust does not sell his soul to the devil.

Five fascinating books about scientists, selected by historian of science Jimena Canales. She explains how the scientific persona has been constructed throughout history and explores the implicit assumptions about agency, subjectivity, and causality that underlie scientific biographies.

The art of Francisco de Goya reflects the social and political chaos of Spain in his day, leaving later generations to read into his prolific work—by turns formal and bizarre, official and fantastic—many often contradictory interpretations. Art historian Janis Tomlinson recommends books that disentangle Goya from the retroactive projections of later admirers and situates him in his own time. We also consider what makes for a compelling biography.

Reading the hieroglyphs of ancient Egypt reveals much about the worldview of a civilisation that rose to prominence 5000 years ago and flourished for thousands of years. Here, intellectual historian Diane Greco Josefowicz—whose book, The Riddle of the Rosetta, co-written with Jed Buchwald, tells the story of how the meaning of the hieroglyphs was deciphered in 19th century France—recommends the best books to learn more about hieroglyphics.

Long before the Europeans arrived in the 16th and 17th centuries, sub-Saharan West Africa saw the emergence of a series of African empires that lasted for centuries and stretched over vast swathes of the continent. They were known as the Ghana, Mali and Songhai Empires. Here, historian Michael Gomez discusses what led to their greatness, what sustained them and why they fell.

The beauty of Shakespeare's sonnets speaks to us down the centuries, their lines peaking out at us from the titles of famous books or enjoying outings at weddings or other romantic occasions. But they were not always regarded as perfectly-formed jewels, and the relationships they portray not as conventional as many of us presume. Here, Shakespeare scholar Scott Newstok talks us through books that help us learn more about Shakespeare's sonnets, from the best introduction to the poems for students through to their afterlife and recent creative interpretations.

Is it possible that Augustus was not the first Roman emperor, but the last of Rome's great populist champions? That's what classicist Peter Wiseman argues in his book, The House of Augustus: A Historical Detective Story. Drawing on a lifetime of research and writing on this period, the emeritus professor of classics and ancient history gives a brilliant overview of the Augustan age, and recommends what to read to better understand the adopted son of Julius Caesar, who found Rome in brick and left it in marble.

Our political systems evolved in an era when information was much harder to come by. What challenges does our current reality of information overload pose for democracy? How do we even start thinking about these questions? Political scientist Henry Farrell proposes key books for building a curriculum on 'the politics of information,' starting with a beautifully written novel.
