What We Can Know

The premise of this book is that we are watching two literary historians in the twenty-second century looking back at the most famous poet of the early years of the twenty-first century. Since the early years of the twenty-first century the world has gone through massive climate change, nuclear wars and is clearly a different place than we know. McEwan has found a fascinating way to talk about the present world, from a unique perspective. We learn back in the long ago that the poet composed a paean to his wife, delivered it at his wife’s birthday at a diner for friends. His wife had the only written copy. All consider this potentially his best work, written in a very difficult form, a corona, but it never gets published. It show more disappears. It becomes the holy grail. Somebody must have a copy.

This is the setup behind the first half of this book. We have two historians, a man and a woman who take on the challenge. They are prepared to do all the hard work to find the missing poem. They are ready to search the archives of all the known participants in the diner to trace who was doing what to whom and what that might tell us about what happened and where the poem could possibly be. Sounds like an easy task. But we learn they face a different world. It’s not just ask AI. They are in a post AI world where just getting around is difficult. England, once a large island, is now, because of sea level changes, a series of islands and London no longer exists. Electricity is scarce. Computers still exist but they are the models of a hundred years ago as no one has access to the rare earth metals needed to create new ones. Archives are difficult to access as they’ve moved to the top of mountains and can only be accessed by funicular and by appointment. But they stumble on a clue and believe that they have discovered that the poem might be buried. They set off to find it. But this is a new book so I’m not going to spill the beans and let you know what happens.

The real treat of this book is the second half. We no longer are in the world of our two historians, we’re back in the world they were investigating and what a different world it turns out to be. We learn what really went on and it’s nothing like what they had imagined based on all the available evidence they came up with by going through all the archives. There’s even a small episode of an abandoned child, reminiscence of McEwan's other works. McEwan’s title now makes perfect sense - What We Can Know, only what the past really wants us to know. There are secrets that no one is sharing even with their closest friends. You’ll have to read the book to find out. It keeps its own secret all the way to the last sentence. Somehow I think a movie is in the works. show less

He called it A Corona for Vivien: fourteen sonnets linked head to tail, each feeding upon the last. A perfect ring — like love, or delusion.” - Ian McEwan 2025

Ian McEwan’s latest novel, Wha We Can Know is an interesting look at our world through the eyes of a scholar. Professor Thomas Metcalfe is living a thousand years in the future, on an island in what was once part of an area in southern England. Coupled with the professor’s personal life in the 22nd century we learn of the world pre and post “the Derangement” which was brought about not with a bang but a whimper.

Great Britain has been reduced to an archipelago. The continents largely under water, major cities have vanished under oceans. Oceans transformed into seas. show more Small islands are scattered throughput the globe, though some large land masses still exist. Nigeria and the USA still exist though changed. The USA has become a battleground of warlords, much like Europe in the time of Charlemagne. All this being the result of wars, AI and the climate crisis which have together brought humanity to a world where a new order is yet to develop.

We see both worlds through the eyes of the 22nd century professor, Tom. He’s immediate research interest is that of finding the lost corona, A poem that was written by the celebrated fictional 21st century English poet Francis Blundy to his wife in the mid 21st century.

There’s lots to keep the reader entertained, love affairs, betrayals, even a murder. Looking at our own world through the eyes of people living in the not so distant future is fascinating. This is unlike so many post apocalypses novels, where the emphasis is on the Earth’s destruction and the distant future. The 22nd century people in the novel are close enough in time to our own zeitgeist for us to relate. It is interesting to speculate on how they see our world and what they understand and what they don’t.

What Can Know is McEwan at his best. The novel entertains, is erudite, clever, and its structure echoes the corona form, the subject of one particular poem being the mystery that is the major plot of the novel.

Highly recommended. show less

Summary: A researcher in 2119 seeks a lost poem read at a famous dinner in 2014, reconstructing the circumstances of the dinner.

In 2014, famous poet Francis Blundy hosted a dinner in honor of his wife’s birthday. During the dinner, he read a poem written for Vivien in the form of a corona. A corona is a “crown of sonnets” consisting of fifteen sonnets, often addressed to one person. The last line of each sonnet is repeated in the first line of the next. Finally, the fifteenth sonnet consists of the last lines of the first fourteen, and makes sense! Blundy wrote it out on vellum and, after the reading, presented it to Vivian, After the dinner, its whereabouts became unknown. The dinner became known as the Second Immortals Dinner. show more The first was in 1817, with Wordsworth, Keats, and Charles Lamb among the guests of painter Ben Haydon.

In the 2030’s, cataclysmic events occurred. Climate change resulted in wars over resources, including the limited use of nuclear weapons. One of these, intended for the United States landed in the mid-Atlantic, creating a giant tsunami inundating the low lying areas of the Americas and Europe and western Africa. Paradoxically, these bombs resulted in a cooling of the planet. The period was called the Derangement and by the following century, the Earth’s population was down to four billion.

McEwan envisions a world in 2119 that suffered both the loss of much and retained the vestiges of advanced civilization. Regions of the United States are at war. Nigeria controls the internet. But there are still universities in what is left of the United Kingdom. Among the researchers, Thomas Metcalfe studies the years prior to the Derangement. His interest has focused in on the dinner and the lost poem. Instead of the coup of discovery, all he can know are the circumstances surrounding the dinner. Particularly, this included the lives and loves of the guests.

He knows of the tragic first marriage of Vivien Blundy to Percy. This big bear of a man built beautiful musical instruments, including working on a replica of a Guarnieri violin. That is, until early onset Alzheimer’s struck. He knows of the dalliances with Blundy’s brother-in-law Harry, and the meeting pf Francis and Vivien. All this took place prior to Percy’s death from a fall. Vivien subsequently married Francis, setting up in her own studio near the main building called the Barn.

But Metcalfe’s career and life seem stalled. He’s in an off again/on again relationship with Rose, a fellow lecturer on the period. They even teach classes together. Research trips to the Blundy archives turn up lots of trivia about the Blundy’s but nothing on the poem. That is, until an archivist passes along a slip of paper. On it are scratched numbers that Thomas figures out are map coordinates.

When students, no longer interested in how writers dealt with or avoided the impending Derangement, walk out of Thomas and Rose’s class, they conclude it’s time to seek out the coordinates. It turns out they are on the site of the home where Vivien lived after Francis’ death. Could this be the poem’s hiding place? Thomas and Rose embark on a boat trip to an isolated island, hike through overgrowth, find the site and dig up a sealed container.

This is all in the first part of the novel. The second part tells us what they found, and will answer the question of what happened to the poem. It reveals how much they did not know. McEwan leaves the impact of discovery to our imagination.

McEwan foregrounds the quest for a lost poem and what a scholar can know of its past, and that of its author. But part of the work he and Rose do is study the literature leading up to the Derangement. The unspoken question is why so many knew and did so much yet failed to do what was needed. McEwan also creates a situation in which civilization doesn’t end in a cataclysm but withers by degree. It is telling that Rose and Thomas’s students take no interest in what they can know of the past but think they can create a future on a blank slate. They take no interest in knowing the folly of forebears who refused to face and act on what they knew.

It leaves one wondering what historians a century from now, if such still exist, will write about our time. And I can’t help wondering if they will write about what we knew and failed to act upon. Will they wonder about our grand projects and petty squabbles while our own Derangement loomed? I wonder. show less

This novel had me from page one: the narrator visits a library. But something is off — the Bodleian is now on a mountain in Snowdonia; Oxford is submerged. Great Britain in the early years of the 22nd century is a “sleepy overlooked archipelago republic”.

So yes, this is one of the many novels to appear in recent years set in the time after. At one point, the narrator, a professor of English literature, reports on the effect of “the Derangement” (as climate change is referred to in retrospect) on fiction a hundred years earlier (that is, our day): “The conventions of fictional realism, with its close attention to the mundane, the personal and the assumed continuity of everyday life, were inadequate. New forms were needed to show more frame the physical and moral consequences of a global catastrophe and certain writers were struggling to find them”. We can now count Ian McEwan among them.

But while this conceit provides the setting, the author’s overriding theme is our obsession with the past and the question of how well a biographer can ever know his subject. Tom, the narrator, specializes in the early 21st-century poet Francis Blundy, either second only to Seamus Heaney or second to none, depending on whom you ask. Tom’s quest is to find — well, not quite the grail, but Bundy’s most famous poem, oddly enough, one that no one has ever read. It was a corona, a series of fifteen interconnected sonnets dedicated to his wife, Vivien, on her fifty-fourth birthday. He prepared only one copy of it, elaborately hand-written on vellum, which he read out to her and their dinner guests. No one knows what became of the scroll after that.

Tom is aided by Rose, a colleague, friend, and then wife. She alternately encourages and cautions him in his obsession; she repeatedly criticizes the license Tom permits himself to fill gaps in the sources with speculation and educated guesses (shades of Edmund Morris’s Reagan bio, Dutch). But their relationship is a love triangle. Tom’s nostalgia for a past from which he is excluded extends to his idealization of Blundy’s wife, Vivien, and Rose resents having a rival for his affections who has been dead for one hundred years. The trope of two literary couples living a century apart reminded me of the premise of A. S. Byatt’s Possession, but McEwan’s treatment of this is his own.

I enjoyed this novel throughout, except for a chapter near the middle that recounted the events of the 21st century and felt like it dragged. But what kicked the novel into high gear for me was the second part, with its subversion of much of the first half. I won’t write more about that, so I will spare the spoiler alert. show less

In 2119, Thomas Metcalf has dedicated his career to researching the Second Immortal Dinner, a 2014 birthday gathering during which a storied poem was read before being lost. Thomas has been searching the records hoping to discover a copy of the lost poem.

Information has been retrieved on the cloud; "we know more about the twenty-first century than it knew about its own past," Thomas states. He has become emotionally involved with his work, idealizing the poet's wife for whom the poem was written, half in love with her.

I conceded that I complained too often about our fallen world. It had always been falling and we had to make a life. from What We Can Know by Ian McEwan

Thomas's world is made up of islands, the population all a lovely pale show more brown who ate vegetarian. In 2053, a hydrogen bomb had caused tsunamis that left Britain a series of islands, and destroyed coastal cities along the Atlantic. He idealizes the past for its diversity of species, the fullness of nature, and condemns people's greed and obliviousness, their love of autocrats, their short-sightedness.

A clue sends Thomas to search for the lost poem, but what he discovers is more startling, and shocking, altering everything he thought he knew.

We idealize the past and people of the past and think we know them. The good old days, we say. But the mystery of the human heart is impenetrable.

The first section may seem dull, but for the tantalizing glimpses into a changed world, but the second part reads like a thriller. So, hold on and enjoy the ride.

What a glorious, thought-provoking novel. I loved how it was structured - beginning a hundred years into the future where the humanities professor is trying to recreate the "Second Immortal Dinner," and falling in love with the female writer, secure in his belief that he really knew these people from a hundred years ago. The second half is from the perspective of the female writer and demonstrates how very wrong the future humanities professor was. I loved the imagery of two people on bridges across a river half a mile or a mile from each other and each in a different time period. Time is so often described as a flowing river. But by the end of the novel, I detested everything about Vivien, the female writer. This is a novel that will show more stick with me for quite a while. show less

McEwan’s uncanny ability to pose interesting moral dilemmas in his fiction has impressed me since reading “Amsterdam.” WHAT WE CAN KNOW is in a similar vein but much more ambitious and daring. Its structure is complex and difficult to classify. Is it a dystopia or literary mystery? Is it a meditation on the historical evolution of knowledge, a romance, an examination of mental illness in aging or just a true crime story? Clearly, it’s all of the above. For me its appeal comes from the big questions McEwan ruminates on and the narrative shifts between two periods roughly a century apart focusing on two interesting, but flawed protagonists.

McEwan alludes to his principal focus in his title. Can we ever really know people and show more events from the past? For that matter, can we ever really know ourselves? How do we muddle our motivations and memories? He wraps all of this in two settings: one contemporary and the other about 100 years into the future.

Thomas Metcalfe is a literature professor living in a much-changed Britain of 2119. It’s now an archipelago due to an inundation caused by a nuclear accident and climate degradation. People now quizzically refer to the latter as “the derangement.” Metcalfe’s research involves a poem written by a major poet for his wife during the early 21st century. The only copy has long-since disappeared. People refer to a birthday gathering where it was read by the author but can only speculate about its content. Likewise McEwan teases with it, but never really reveals much about it. Metcalfe’s academic reputation rests on finding that poem, but his research seems to have reached a dead end.

Vivien Blundy is probably one of McEwan’s most complex female characters. She is the poet’s wife. Francis Blundy is her second husband. Her first died of Alzheimer’s shortly before she married the poet. She readily explores her sexuality, while providing a care giving role for her first husband. Moreover, she sacrifices a promising academic career to dutifully serve her second. Francis clearly has abundant talent and fame but also is a self-involved narcissist.

McEwan crafts an intriguing relationship between Thomas and Vivien in spite of a time/space gap that would be daunting for most writers. While never losing focus on the story, he challenges his characters to navigate complex relationships and personal ambitions. The dual settings also provide an opportunity to reflect on the present from the perspective of an uncertain future.

As we have come to expect from McEwan, the prose is polished and reflective. Yet the slow pace requires patience. For those expecting a high-stakes thriller, searching for a lost poem may seem ho-hum. However, the scenes where Thomas searches for it in a surprisingly hostile environment are indeed gripping.

While questions abound in the novel, solid answers are not readily apparent. Maybe that’s the point. We can’t know everything. show less
