Philosophy

How do you write a group biography of people who never actually formed a group? Such is the challenge Wolfram Eilenberger sets himself in a book about the philosophers Martin Heidegger, Ludwig Wittgenstein, Walter Benjamin and — the surprisingly unstarry fourth subject — Ernst Cassirer, an urbane and now nearly forgotten neo-Kantian who might have deserved the made-up title of ‘symbologist’, thus far reserved for the heroes of Dan Brown’s novels. What these men have in common is that they spoke German and were philosophically active during the 1920s, but that is about it. Heidegger and Cassirer met and traded rhetorical blows at a celebrated philosophy conference in Davos; Benjamin

Some books elucidate their subject, mapping and sharpening its boundaries. The Clock Mirage, by the mathematician Joseph Mazur, is not one of them. Mazur is out to muddy time’s waters, dismantling the easy opposition between clock time and mental time, between physics and philosophy, between science and feeling. That split made little sense even in 1922, when the philosopher Henri Bergson and the young physicist Albert Einstein (much against his better judgment) went head-to-head at the Société française de philosophie in Paris to discuss the meaning of relativity. (Or that was the idea. Actually they talked at complete cross-purposes.) Einstein won. At the time, there was more novel insight to

‘You’re never alone with a Strand,’ went the misbegotten advertisement for a new cigarette in 1959. What the copywriter didn’t realise is that smokers often smoke to be alone. As Mass Observation had reported a decade earlier: In an increasingly gregarious world, where fewer and fewer habits and pastimes are entirely individual, the cigarette remains for most people a pleasure that, whatever its social significance, can be enjoyed in entire solitude, and a pleasure that remains entirely individual. At the time, 80 per cent of British men and 40 per cent of women were regular smokers. Smoking was not just a means of inhaling death and of escaping the dead

The reality (or lack thereof) of numbers is the kind of problem some philosophers consider overwhelmingly important, but it’s of no consequence to just about everyone else. It does not make a wink of difference to your life whether the figures in your bank account or the digits on your clock are, in a philosophical sense, really real, so long as they work as expected. The mathematician Paolo Zellini’s book, now translated by Simon Carnell and Erica Segre from the 2016 Italian original, does not exactly elevate the number-reality problem to a matter of concern to non-philosophers, and certainly does not explain the problem in a way that will make

Surely God, if He existed, would find a major source of entertainment down the ages in the activities of theologians, reaching their climax perhaps in the 19th century, when they involved Him with German idealism, and then the descent from that to the present day, when the sheer naivete of anyone who thinks that God is ‘out there’ or actually exists, in some sense we can understand, provokes genial and condescending ridicule from the professionals. Central to the development of thought about Christianity is the work of the melancholy Dane Søren Kierkegaard, who in the course of his short life — he died, aged 42, in 1855 — wrote more

Descartes is most generally known these days for being the guy who was sure he existed because he was thinking. But before he devoted himself to metaphysical meditations, he had spent a decade as a soldier-scholar travelling the hotspots of Europe. How might a greater understanding of this period affect our view of the great man? This is a fascinating if dry kind of pre-intellectual biography, which hopes to hint at how the philosophy grew out of the action. René Descartes was born to a family of minor nobility in 1596, and educated by Jesuits. He studied some mathematics in Paris and then acquired a degree in law, after which

Alan Querry, the central figure in James Wood’s second novel, is someone who, in his own words, doesn’t ‘think about life too much’. His peculiar surname may recall the brooding, godforsaken Querry of Graham Greene’s A Burnt-Out Case, but this Querry — who lives in ‘the poshest part of Northumberland’ — isn’t much troubled by God’s presence or absence: ‘he had a notion that “the question of God” might all have been more or less sorted out in his lifetime, like Cyprus or polio.’ Called upon to visit his daughter Vanessa in upstate New York, Alan stops along the way to meet his younger daughter, Helen, and they make the

The precarious stasis of late pregnancy offers the narrator of Jessie Greengrass’s exceptional first novel a space — albeit an uncomfortable one — for reflection. She sifts through her own immediate and past experience: caring for her dying mother in her early twenties; her relationship with her partner Johannes; her childhood; the birth of her first child. This fragmented narrative is intercut with the stories of Wilhelm Conrad Röntgen, the inventor of the X-ray; Sigmund and Anna Freud; and the 18th-century anatomist, surgeon and empiricist John Hunter — along with other brief cameos from the history of science, from the Lumière brothers to the engraver Jan van Rymsdyk. These figures

Losing our way in life’s trackless forest, whither should we turn for solace and advice? Wisdom used to be the special province of our elders, though for no better reason than that old people were less common than they are now. Aristotle had their measure: ‘As they have a lot of experience,’ he wrote, ‘they are sure about nothing, and under-do everything.’ Now the old are as common as grass, and we draw the truth about life experience as much as possible from the source. If you want to know how a child feels, ask a child. If you want a considered opinion about Muslim dress codes, stop opining into

Is Enlightenment rationalism overrated? Do we spend too much time thinking and not enough time letting our conscious thoughts scatter to the winds? My guest in this week’s Books Podcast is the philosopher Jules Evans, who argues that we human beings have a deep need to get out of our heads. We talk about his new book The Art of Losing Control: A Philosopher’s Search for Ecstatic Experience – in which he explores everything from extreme meditation to tantric swinging parties, from the sublime in Romantic art to the latest findings in psychedelic drug use. Learn what a near-death experience feels like (Jules has had one) – and wonder, with

In 2012, sugar became more dangerous than gunpowder. According to the historian Yuval Noah Harari, of the 56 million people who died that year, 620,000 did so by the hand of their fellow humans: 120,000 in war and 500,000 from crime. By contrast, 1.5 million died from diabetes. Harari’s wry observation adds weight to Steven Pinker’s assertion in The Better Angels of Our Nature (2011) that humans are on a trajectory towards peace and non-violence. But wars in the Middle East, Afghanistan, across the Sahel and Yemen; Russian and Chinese irredentism; nuclear threats from North Korea; Trump’s belligerency, not to mention the asymmetry of terrorism, render urgently relevant the continued
