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 Yakov loves 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…

Book cover of The Animal In The Mirror

The Animal In The Mirror by Arnie Benn,

The Animal in the Mirror is a wake-up call to your higher self. Why do we keep reacting, fearing, and repeating the same patterns—no matter how much we know better? Because beneath our thoughts and emotions still lives the animal within: the ancient survival instinct that once kept us alive…

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

Yakov Ben-Haim Why Yakov loves 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 Yakov loves 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.

By Philip Freeman ,

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 Yakov loves 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?

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 Simon loves 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 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 William loves 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…

Book cover of The Ethics of Authenticity

Adam Ellwanger Author Of Metanoia: Rhetoric, Authenticity, and the Transformation of the Self

From my list on why looking for your ‘true self’ is pointless.

Why am I passionate about this?

I'm a professor of rhetoric at the University of Houston – Downtown. In addition to my academic research, I write political and cultural commentary for a variety of right-of-center online publications. Much of my own work focuses on how individuals come to be persuaded about who they are. I argue that much of the frustration people feel when searching for their authentic identity is due to the fact that the existence of the hidden ‘true self’ is an illusion. The quest for authenticity is never complete. The good news, though, is that you can put an end to the suffering… only if you’re willing to give up the fevered pursuit of the “true self.”

Adam's book list on why looking for your ‘true self’ is pointless

Adam Ellwanger Why Adam loves this book

If you want to learn about the history of the concept of authenticity and how it is understood in the western world, this is probably the best book to read (after my book, of course!). Charles Taylor is one of the most prominent living philosophers of selfhood, and this book (topping out at only a little over 100 pages) is an easy-to-read digestion of the ideas that he elaborated in his much-longer book Sources of the Self. Taylor is ambivalent about whether personal authenticity is a good or a bad thing in our era. He recognizes the harms imposed by some of the debased forms that it takes in modern society, but Taylor also tries to articulate an ethics that could rehabilitate authenticity in a way that affirms the dignity of and respect for each individual. I don’t like the fence-sitting, but this remains required reading.

What is this book about?

Everywhere we hear talk of decline, of a world that was better once, maybe fifty years ago, maybe centuries ago, but certainly before modernity drew us along its dubious path. While some lament the slide of Western culture into relativism and nihilism and others celebrate the trend as a liberating sort of progress, Charles Taylor calls on us to face the moral and political crises of our time, and to make the most of modernity's challenges.

"The great merit of Taylor's brief, non-technical, powerful book...is the vigor with which he restates the point which Hegel (and later Dewey) urged against…


Book cover of Towards the Light: The Story of the Struggles for Liberty and Rights that Made the Modern West

Russell Blackford Author Of How We Became Post-Liberal: The Rise and Fall of Toleration

From my list on history of liberalism five persuasive perspectives.

Why am I passionate about this?

I’m a philosopher and author from Australia with a special interest in defending liberal rights and freedoms. For many years now, I’ve been worried about the erosion of liberalism in its fundamental sense that relates to individual liberty. Everywhere we look, unfortunately – and from all sides of politics – there are pressures to conform and attacks on free inquiry and speech. All too often, what’s worse, we cave in to those pressures and attacks. I value deep scholarship and intellectual rigor but also clear, vivid writing. I aim for those qualities in my own books and articles, and I’m sure you’ll find them in the five books on my list.

Russell's book list on history of liberalism five persuasive perspectives

Russell Blackford Why Russell loves this book

The famous British philosopher A.C. Grayling tells the story of a hard-fought struggle over the past five centuries for the rights and freedoms now enjoyed in Western democracies. He emphasizes that our rights and freedoms are both precious and precarious: they could easily be lost if governments and citizens don’t adequately appreciate them or don’t understand how difficult they are to win.

For Grayling, our rights and freedoms began to contract around the beginning of this century. He points, for example, to the rise of state surveillance, particularly in response to terrorism but often just for the convenience of policing.

As Grayling passionately affirms, it is a story - and a struggle - that continues to this day as those in power use the threat of terrorism in the 21st century to roll-back the liberties that so many have fought and died to win for us.

Book cover of The Scottish Enlightenment: The Scots' Invention of the Modern World

Billy Kay Author Of The Scottish World: A Journey Into the Scottish Diaspora

From my list on proving the world, and the Universe, is Scottish.

Why am I passionate about this?

Very little Scottish history or culture was taught in school when I was growing up in the 1950s and 1960s. When I began to read books on the subject from the local library and then studied Scottish literature at Edinburgh University, I realised what my brother and sister Scots had missed out on, and was determined to rectify that by writing accessible books which would both inform and entertain as well as enrich their lives and change the way they perceived their culture. I love their reaction to my work and the influence my books have had. 

Billy's book list on proving the world, and the Universe, is Scottish

Billy Kay Why Billy loves this book

The British edition of this provocative book has the modest title The Scottish Enlightenment with the subheading The Scots’ Invention of the Modern World. I have the original in-your-face American edition though, which rejoices in a title that no Scot would have the brass neck to come up with: How the Scots Invented the Modern World with the subheading The True Story of How Western Europe’s Poorest Nation Created Our World & Everything in It. It was given to me by a Philipino-Californian surfing lawyer, Jesse Quinsaat, who studied with me at Edinburgh University in the early 1970s and continues his interest in Scottish culture when surf’s not up or the cases are not too demanding! He had bought the book in San Diego, loved it, and passed it on to me during a visit to Edinburgh.

A dramatic and intriguing history of how Scotland produced the institutions, beliefs and human character that have made the West into the most powerful culture in the world.

Arthur Herman argues that Scotland's turbulent history, from William Wallace to the Presbyterian Lords of the Covenant, laid the foundations for 'the Scottish miracle'. Within one hundred years, the nation that began the eighteenth century dominated by the harsh and repressive Scottish Kirk had evolved into Europe's most literate society, producing an idea…


Book cover of Future Shock

Jerry Fishenden Author Of Fracture. The collision between technology and democracy-and how we fix it

From my list on technology and democracy.

Why am I passionate about this?

I’ve always loved technology. I like the constant change, the sense of creativity and invention, of how it can act as an incredible force for good and human progress and betterment in the world. I can’t remember a time when I wasn’t tinkering with gadgets—taking radios apart to mend them or learn how they worked; designing electronic circuits for music synthesis; programming computers. But I’ve also always been interested in politics and the complex intersection of technology and public policy. So much so that most of my working life has been spent at this intersection, which is why I love these books—and hope you will too.

Jerry's book list on technology and democracy

Jerry Fishenden Why Jerry loves this book

I remember first reading Future Shock after buying a battered, orange-coloured paperback edition at a bargain price from one of the second-hand bookshops that once saturated London’s Charing Cross Road.

It hadn’t really occurred to me before how much the increasingly rapid technological changes around us might create a sense of shock—‘future shock’— for some people. It changed my thinking about the influence of technology on our world and the impact it has on people, society, economics, and politics.

Even after all these years, many of Alvin Toffler’s insights and ideas remain just as topical today.
