Book cover of A Question of Standing: The History of the CIA

Yakov Ben-Haim Author Of The Dilemmas of Wonderland: Decisions in the Age of Innovation

From my list on making decisions when you don’t know what’s going on.

Why am I passionate about this?

I am a retired university professor. My research, in which I am still actively engaged, deals with decision-making under deep uncertainty: how to make a decision, or design a project, or plan an operation when major relevant factors are unknown or highly uncertain. I developed a decision theory called info-gap theory that grapples with this challenge, and is applied around the world in many fields, including engineering design, economics, medicine, national security, biological conservation, and more.

Yakov Ben-Haim Why did Yakov love this book?

This is an interesting collection of essays on the history of the CIA.

A spy agency thrives on deceit and uncertainty, making plans and taking actions when the adversary also thrives on those same elements.

Arranged in chronological order, the essays cover nearly 20 different incidents, describing the challenges, uncertainties, goals, and decisions made by both high-level political decision-makers and practitioners in the field.

Topics covered include early stages in the development of the CIA (founded in 1947), including covert action against the Soviet Union in the 1950s, the Bay of Pigs (1961), the Iran-Contra affair (mid-1980s), up to more recent events with bin Laden, fake news, and more.

What is this book about?

A Question of Standing deals with recognizable events that have shaped the history of the first 75 years of the CIA. Unsparing in its accounts of dirty tricks and their consequences, it values the agency's intelligence and analysis work to offer balanced judgements that avoid both celebration and condemnation of the CIA.

The mission of the CIA, derived from U-1 in World War I more than from World War II's OSS, has always been intelligence. Seventy-five years ago, in the year of its creation, the National Security Act gave the agency, uniquely in world history up to that point, a…

Yakov's book list on making decisions when you don’t know what’s going on

Yakov Ben-Haim Why did Yakov love this book?

War is the realm of uncertainty. Clausewitz sums this up by referring to the "fog of war".

Military commanders must confront this uncertainty, making far-reaching decisions when the fog of war obscures their understanding of the situation and the implications of their actions.

The book contains concise professional and historical biographies of 6 generals of the IDF, serving from early 1973 (prior to the Yom Kippur War) to 2013. The studies focus on decisions made – or not made – by these generals, the uncertainties that they confronted, and the military, political and social constraints they faced.

An interesting aspect is the personal and individualistic nature of the decision-making process. While military activity has a long history and much theory, it is more of an art than a science. The art of war, and of preventing war, is very personal, and it differs from one general to another. Some generals…

What is this book about?

The commander, or chief of staff, of the Israel Defense Forces (IDF) is a prominent public figure in Israel. His decisions, advice, and persona exert direct influence on force design and military strategy, and indirectly impact social, economic, and foreign affairs. This first-ever in-depth comparative study on the role and performance of the IDF chiefs of staff throughout modern Israel's history offers lessons for practitioners and students of strategy, military history, and leadership everywhere.

Yakov's book list on making decisions when you don’t know what’s going on

Yakov Ben-Haim Why did Yakov love this book?

This is a very readable account of Hannibal and his exploits, though it’s perhaps a somewhat idealized, romantic, and heroic portrayal of the man. Nonetheless it’s a great read.

The book follows Hannibal’s many military exploits in Carthage, Sicily, Spain, and many more, up to Cannae, Rome, and his ultimate fall from power and exile.

One sees the continual tension between three factors: Hannibal’s military genius in making military decisions despite deep uncertainty about his own capabilities and about the adversary's intentions, the military genius of his opponents, and the ruthless hand of uncertainty in human history. Hannibal’s life illustrates all three factors.

1 author picked Hannibal as one of their favorite books, and they share why you should read it.

What is this book about?

Telling the story of a man who stood against the overwhelming power of the mighty Roman empire, Hannibal is the biography of a man who, against all odds, dared to change the course of history.

Over two thousand years ago one of the greatest military leaders in history almost destroyed Rome. Hannibal, a daring African general from the city of Carthage, led an army of warriors and battle elephants over the snowy Alps to invade the very heart of Rome's growing empire. But what kind of person would dare to face the most relentless imperial power of the ancient world?…

Yakov Ben-Haim Why did Yakov love this book?

The author presents a reasoned rational explanation of historical events: Agents act rationally from self-interest. History makes sense.

As I read the book, I was challenged to ask: how rational is human behavior? What does rationality mean in a world that we hardly understand because it is fraught with uncertainty?

Uncertainty and surprise are important in history: What will be the next revolutionary invention? Who will be the next charismatic leader? What new ideology will sweep away conventions? Does history really make sense? Can we really make rational decisions when we face deep uncertainty about the world?

1 author picked The Pursuit of Power as one of their favorite books, and they share why you should read it.

What is this book about?

In this magnificent synthesis of military, technological, and social history, William H. McNeill explores a whole millennium of human upheaval and traces the path by which we have arrived at the frightening dilemmas that now confront us. McNeill moves with equal mastery from the crossbow-banned by the Church in 1139 as too lethal for Christians to use against one another-to the nuclear missile, from the sociological consequences of drill in the seventeenth century to the emergence of the military-industrial complex in the twentieth. His central argument is that a commercial transformation of world society in the eleventh century caused military…


Book cover of The Shortcut: Why Intelligent Machines Do Not Think Like Us

Simon J.D. Prince Author Of Understanding Deep Learning

From my list on machine learning and deep neural networks.

Why am I passionate about this?

I started my career in neuroscience. I wanted to understand brains. That is still proving difficult, and somewhere along the way, I realized my real motivation was to build things, and I wound up working in AI. I love the elegance of mathematical models of the world. Even the simplest machine learning model has complex implications, and exploring them is a joy.

Simon's book list on machine learning and deep neural networks

Simon J.D. Prince Why did Simon love this book?

This is a popular science book, so a little different from the others on this list. It is a beautifully written book that is accessible to people who don’t know much about AI but is simultaneously thought-provoking for experts.

It contains probably the best discussion of "intelligence" that I've read, interesting insights into how Google and other tech giants came to develop their machine learning strategy, and a fascinating chapter that views recommendation engines and their users as parts of a single intelligent organism. It's concise and easy to read.

I've read many popular AI books, which are highly variable in quality, and this criminally underappreciated work is the best by miles. 

By Nello Cristianini,

Why should I read it?

1 author picked The Shortcut as one of their favorite books, and they share why you should read it.

What is this book about?

- The author is one of the most influential AI reseachers of recent decades.

- Written in an accessible language, the book provides a probing account of AI today and proposes a new narrative to connect and make sense of events that happened in the recent tumultuous past and enable us to think soberly about the road ahead.

- The book is divided into ten carefully crafted and easily-digestible chapters, each grapples with an important question for AI, ranging from the scientific concepts that underpin the technology to wider implications for society, using real examples wherever possible.


Book cover of The Scottish World: A Journey Into the Scottish Diaspora

Claire R. McDougall Author Of Veil of Time

From my list on to lose yourself in the dream that is Scotland.

Why am I passionate about this?

There is a saying that you can take the girl out of Scotland but not Scotland out of the girl. I am that girl. Born and raised in Scotland, I earned an MA from Edinburgh University and a M.Litt from Oxford. I met my husband during the summer at  Dartmouth College and the rest, as they say, is history. Or, at least it would be, except for the hankering back to Scotland that never leaves. My novel set in Scotland was published by Simon & Schuster.

Claire's book list on to lose yourself in the dream that is Scotland

Claire R. McDougall Why did Claire love this book?

I value this book because, since joining the United Kingdom in 1707, much of Scottish history has been disregarded. Even though I studied history in my Scottish school to a high level, the details of our past were replaced with English history. Well-known radio personality, Billy Kay, brings together a wealth of information about Scotland’s outside influence through the ages. Scotland was one of the first countries to see the benefit of an educated working class, and in the countries to which they emigrated, their learning stood them in good stead. Scottish culture, over hundreds of years before it was incorporated into the United Kingdom, had well-established cultural centers throughout Europe and even as far as Russia.

Book cover of The Swerve: How the World Became Modern

Benjamin Hoffmann Author Of The Paradoxes of Posterity

From my list on why people write books.

Why am I passionate about this?

I grew up in Bordeaux, a city that became prominent during the eighteenth century. My hometown inspired my love of eighteenth-century French studies, which led me to the Sorbonne, then to Yale University where I earned a PhD. Today, I am an Associate Professor at The Ohio State University. I am the author of eight novels and monographs published in France and the US, including American Pandemonium, Posthumous America, and Sentinel Island. My work explores numerous genres to question a number of recurring themes: exile and the representation of otherness; nostalgia and the experience of bereavement; the social impact of new technologies; America’s history and its troubled present.

Benjamin's book list on why people write books

Benjamin Hoffmann Why did Benjamin love this book?

While The Swerve is not exactly a book about posterity, it nonetheless provides a wonderful case study of a text that remained on the verge of destruction for centuries, before going on to play a tremendously influential role in shaping our modern world. This book is none other than On The Nature of Things by Lucretius –one of the foundational texts of Western culture, whose impact was postponed to the fifteenth century, as it would not have seen the light of day without its serendipitous rediscovery in a German monastery by Poggio Bracciolini (1380-1459). This gripping work offers a fascinating example of the delayed reception of a prominent cultural object, a proof of its extraordinary resilience, and, at the same time, an illustration of the role played by chance and accidents on the transmission of texts to posterity.

5 authors picked The Swerve as one of their favorite books, and they share why you should read it.

What is this book about?

In the winter of 1417, a short, genial, cannily alert man in his late thirties plucked a very old manuscript off a dusty shelf in a remote monastery, saw with excitement what he had discovered, and ordered that it be copied. He was Poggio Bracciolini, the greatest book hunter of the Renaissance. His discovery, Lucretius' ancient poem On the Nature of Things, had been almost entirely lost to history for more than a thousand years.

It was a beautiful poem of the most dangerous ideas: that the universe functions without the aid of gods, that religious fear is damaging to…


Book cover of Wealth Explosion: The Nature and Origins of Modernity

Johan Norberg Author Of Open: The Story of Human Progress

From my list on to make you grateful you live today.

Why am I passionate about this?

I did not use to believe in human progress, but thought there must have been good old days behind us – until I studied history and understood that my ancestors did not live ecologically, they died ecologically, at an early age. Since then I’ve been obsessed with progress, what makes it possible and how we can spread it to more people. I am a historian of ideas from Sweden, the host of a video series on innovations in history, New and Improved, and the writer of many books on intellectual history and global economics, translated into more than 25 languages.

Johan's book list on to make you grateful you live today

Johan Norberg Why did Johan love this book?

The great fact of economic history is that we all used to be poor, and now most of us are not. 200 years ago, almost 90 percent of the world’s population lived in extreme poverty, today around 9 percent does. This is the story of that remarkable transformation and what made it possible. Of course, there are many good books on this, and I have greatly enjoyed for example Joel Mokyr, Deirdre McCloskey, and David Landes, but this is a powerful, short book by a great historian, that manages to weave together economic, political, technological and intellectual factors into a very compelling narrative of progress and its preconditions over the past one thousand years.

How did the modern dynamist economy of wealth and opportunity come about? This major new analytical work emphasizes the often surprising, fundamental and continuing processes of innovation and transformation which has produced the world we live in now. / Today we live in a social and economic world that is fundamentally different from the one inhabited by our ancestors. The difference between the experience of people living today and that of all of our ancestors back to the advent of agriculture is as great as that between them and their hunter-gatherer forebears. The processes of transformational changes could have started…


Book cover of The Climate of History in a Planetary Age

Jeremy Bendik-Keymer Author Of Involving Anthroponomy in the Anthropocene: On Decoloniality

From my list on how we got to climate change and mass extinction.

Why am I passionate about this?

I’m the grandson of a coal miner from a multi-generational, Ohio family. What matters most to me is having some integrity and being morally okay with folks. I never thought of myself as an environmentalist, just as someone trying to figure out what we should be learning to be decent people in this sometimes messed-up world. From there, I was taken into our environmental situation, its planetary injustice, and then onto studying the history of colonialism. This adventure cracked open my midwestern common sense and made me rethink things. Happily, it has only reinforced my commitment to, and faith in, moral relations, giving our word, being accountable, and caring.

Jeremy Bendik-Keymer Why did Jeremy love this book?

I love how Dipesh’s book shows a historian at the height of his powers explaining how history has become geological. Decades ago, Chakrabarty began as someone arguing for a history that made Europe “provincial”. Now he argues that all human history is relative to planetary time. His writing is infused with humanism and is up to date on Earth System Science.

Why should I read it?

1 author picked The Climate of History in a Planetary Age as one of their favorite books, and they share why you should read it.

What is this book about?

For the past decade, historian Dipesh Chakrabarty has been one of the most influential scholars addressing the meaning of climate change. Climate change, he argues, upends long-standing ideas of history, modernity, and globalization. The burden of The Climate of History in a Planetary Age is to grapple with what this means and to confront humanities scholars with ideas they have been reluctant to reconsider-from the changed nature of human agency to a new acceptance of universals.

Chakrabarty argues that we must see ourselves from two perspectives at once: the planetary and the global. This distinction is central to Chakrabarty's work-the…


Book cover of The Palliative Society: Pain Today

William Byers Author Of How Mathematicians Think: Using Ambiguity, Contradiction, and Paradox to Create Mathematics

From my list on thinking, creativity, and mathematics.

Why am I passionate about this?

I'm a mathematician but an unusual one because I am interested in how mathematics is created and how it is learned. From an early age, I loved mathematics because of the beauty of its concepts and the precision of its organization and reasoning. When I started to do research I realized that things were not so simple. To create something new you had to suspend or go beyond your rational mind for a while. I realized that the learning and creating of math have non-logical features. This was my eureka moment. It turned the conventional wisdom (about what math is and how it is done) on its head.

William's book list on thinking, creativity, and mathematics

William Byers Why did William love this book?

It’s a little weird that this book should find a place on my list. It’s a book about how society has become resistant to anything that is difficult and painful and the kinds of people that we have become as a result. But mathematics is difficult! To understand mathematics you have to think hard, sometimes for a long time. Moreover understanding something hard is discontinuous, it requires a leap to a new way of thinking. You have to start with a problem and this problem might be an ambiguity or a contradiction. A is true and B is true but A and B seem to contradict one another. When you sort out this problem you will have learned something.

The moral here is to embrace things that are difficult if you want to learn significant new things. “No pain, no gain.” You don’t have to worry about some super AI…

1 author picked The Palliative Society as one of their favorite books, and they share why you should read it.

What is this book about?

Our societies today are characterized by a universal algophobia: a generalized fear of pain. We strive to avoid all painful conditions - even the pain of love is treated as suspect. This algophobia extends into society: less and less space is given to conflicts and controversies that might prompt painful discussions. It takes hold of politics too: politics becomes a palliative politics that is incapable of implementing radical reforms that might be painful, so all we get is more of the same.

Faced with the coronavirus pandemic, the palliative society is transformed into a society of survival. The virus enters…
