The 16 Best Books of 2016

Rewarding reads on love, life, knowledge, history, the future, and tools for thinking. Out of all the books I read this year, here is a list of what I found most worth reading in 2016.

1. The Psychology of Man’s Possible Evolution
These lectures, which were originally called Six Psychological Lectures, were first privately printed in the 1940s. Of the first run of 150 copies, none were sold. The essays were published once again after Ouspensky’s death, and unlike last time became a hit. While the book is about psychology, it’s different than what we think of as psychology — “for thousands of years psychology existed under the name philosophy.” Consider this a study in what man may become — by working simultaneously on knowledge and inner unity.

2. The Island of Knowledge: The Limits of Science and the Search for Meaning
Imagine the sum of our knowledge as an Island in a vast and endless ocean. This is the Island of Knowledge. The coastline represents the boundary between the known and unknown. As we grow our understanding of the world, the Island grows and with it so does the shores of our ignorance. “We strive toward knowledge, always more knowledge,” Gleiser writes, “but must understand that we are, and will remain, surrounded by mystery.” The book is a fascinating and wide-ranging tour through scientific history. (Dig Deeper into this amazing read here.)

3. When Breath Becomes Air
It’s been a while since I’ve cried reading a book. This beautifully written memoir, by a young neurosurgeon diagnosed with terminal cancer, attempts to answer the question What makes a life worth living? If you read this and you’re not feeling something you’re probably a robot.

4. The Sovereign Individual: Mastering the Transition to the Information Age
The book, which argues “the information revolution will destroy the monopoly power of the nation-state as surely as the Gunpowder Revolution destroyed the Church’s monopoly,” is making the rounds in Silicon Valley and being passed around like candy. Even if its forecasts are controversial, the book is a good read and it’s full of interesting and detailed arguments. I have underlines on nearly every page. “Information societies,” the authors write, “promise to dramatically reduce the returns to violence … When the payoff for organizing violence at a large scale tumbles, the payoff from violence at a smaller scale is likely to jump. Violence will become more random and localized.” The Sovereign Individual, who, for the first time “can educate and motivate himself,” will be “almost entirely free to invest their own work and realize the full benefits of their own productivity.” An unleashing of human potential which will, the authors argue, shift the greatest source of wealth to ideas rather than physical capital — “anyone who thinks clearly will potentially be rich.” Interestingly, in this potential transition, the effects are “likely to be centered among those of the middle talent in currently rich countries. They particularly may come to feel that information technology poses a threat to their way of life.” The book predicts the death of politics, “weakened by the challenge from technology, the state will treat increasingly autonomous individuals, its former citizens, with the same range of ruthlessness and diplomacy it has heretofore displayed in its dealings with other governments.” As technology reshapes the world, it also “antiquates laws, reshapes morals, and alters preconceptions. This book explains how.”

5. To Kill a Mockingbird
I know, I know. Hear me out. Someone I respect mentioned that he thought Atticus Finch was the perfect blend of human characteristics. Tough and skilled, yet humble and understanding. He’s frequently rated as a “most admired” hero in fiction, yet he’s a lawyer competing with Jedis, Detectives, Spies, and Superheroes. Isn’t that kind of interesting? Since it had been at least 15 years since I’d read TKM, I wanted to go back and remember what made Atticus so admired. His courage, his humility, his understanding of people. I forgot just how perceptive Finch was when it came to what we’d call “group social dynamics” — he forgives the individual members of the mob that show up to hurt Tom Robinson simply because he understands that mob psychology is capable of overwhelming otherwise good people. How many of us would be able to do that? Atticus Finch is certainly a fictional, and perhaps “unattainably” moral hero. But I will point out that not only do real life “Finch’s” exist, but that even if we don’t “arrive” at a Finchian level of heroic integrity and calm temperament, it’s certainly a goal worth pursuing. Wise words from the book Rules for a Knight sums it up best: “To head north, a knight may use the North Star to guide him, but he will not arrive at the North Star. A knight’s duty is to proceed in that direction.” (Here are some of the lessons I took away from the book.)

6. Lee Kuan Yew: The Grand Master’s Insights on China, the United States, and the World
If you’re not familiar with Lee Kuan Yew, he’s the “Father of Modern Singapore,” the man who took a small, poor island just north of the equator in Southeast Asia with GDP per capita of ~$500 in 1965 and turned it into a modern powerhouse with GDP per capita of over $70,000 as of 2014, with some of the lowest rates of corruption and highest rates of economic freedom in the world. Finding out how he did it is worth anyone’s time. This book is a short introduction to his style of thinking: A series of excerpts of his thoughts on modern China, the modern U.S., Islamic Terrorism, economics, and a few other things. It’s a wonderful little collection. (We’ve actually posted about it before.) Consider this an appetizer (a delicious one) for the main course: From Third World to First, Yew’s full account of the rise of Singapore. (Dig deeper here.)

7. An Illustrated Book of Bad Arguments
Perfect summer reading for adults and kids alike. One friend of mine has created a family game where they all try to spot the reasoning flaws of others. The person with the most points at the end of the week gets to pick where they go for dinner. I have a suspicion his kids will turn out to be politicians or lawyers.

8. Intuition Pumps and Other Tools for Thinking
Dan Dennett is one of the most well known cognitive scientists on the planet . This book is a collection of 77 short essays on different “thinking tools,” basically thought experiments Dennett uses to slice through tough problems, including some tools for thinking about computing, thinking about meaning, and thinking about consciousness. Like Richard Feynman’s great books, this one acts as a window into a brilliant mind and how it handles interesting and difficult problems. If you only walk away with a few new mental tools, it’s well worth the time spent. (You can learn a lot more about Dennett here, here, and here.)

9. The Seven Sins of Memory (How the Mind Forgets and Remembers)
I found this in the bibliography of Judith Rich Harris’ No Two Alike. Schacter is a psychology professor at Harvard who runs the Schacter Memory Lab. The book explores the seven “issues” we tend to find with regard to our memory: Absent-mindedness, transience, blocking, misattribution, suggestibility, bias, and persistence. The fallibility of memory is so fascinating: We rely on it so heavily and trust it so deeply, yet as Schacter shows, it’s extremely faulty. It’s not just about forgetting where you left your keys. Modern criminologists know that eyewitness testimony is deeply flawed. Some of our deepest and most hard-won memories — the things we know are true — are frequently wrong or distorted. Learning to calibrate our confidence in our own memory is not at all easy. Very interesting topic to explore. (We did a three part series on this book. Introduction and parts One, Two, and Three).

10. Talk Lean: Shorter Meetings. Quicker Results. Better Relations
This book is full of useful tips on listening better, being candid and courteous, and learning what derails meetings, conversations, and relationships with people at work. Don’t worry. It’s not about leaving things unsaid that might be displeasing for other people. In fact, leaving things unsaid is often more detrimental to the relationship than airing them out. Rather, it’s about finding a way to say them so people will hear them and not feel defensive. If you want to get right to the point and not alienate people, this book will help you. I know because this is something, personally, I struggle with at times.

11. The Master Algorithm: How the Quest for the Ultimate Learning Machine Will Remake Our World
I recently had a fascinating multi-hour dinner with the author, Pedro Domingos, on where knowledge comes from. Historically, at least, the answer has been evolution, experience, and culture. Now, however, there is a new source of knowledge: Machine learning. The book offers an accessible overview of the different ways of machine learning and the search for a master, unifying, theory. The book also covers how machine learning works and gives Pedro’s thoughts on where we’re headed. (Dig deeper in this podcast.)

12. Why Don’t We Learn from History?
This is a short (~120pp) book by the military historian and strategist B.H. Liddell Hart, a man who not only wrote military history but surely influenced it, especially in Germany in the World War period. He wrote this short synthesis at the end of his life and didn’t have a chance to finish it, but the result is still fascinating. Hart takes a “negative” view of history; in other words, What went wrong? How can we avoid it? The result of that study, as he writes in the introduction, is that “History teaches us personal philosophy.” Those who learn vicariously as well as directly have a big leg up. Something to take to heart. I plan to read more of his works.

13. A Powerful Mind: The Self-Education of George Washington
What a great book idea by Adrienne Harrison. There are a zillion biographies of GW out there, with Chernow's getting a lot of praise recently. But Harrison narrows in on Washington’s self-didactic nature. Why did he read so much? How did he educate himself? Any self-motivated learner is probably going to enjoy this.

14. Sapiens: A Brief History of Humankind
One of the best books I’ve come across in a long time. Sapiens is a work of “Big History” — in the style of Jared Diamond’s Guns, Germs, and Steel — that seeks to understand humanity in a deep way. Many of Professor Harari’s solutions will be uncomfortable for some to read, there is no attempt at political correctness, but his diagnosis of human history is undeniably interesting and at least partially correct. He draws on many fields to arrive at his conclusions; a grand method of synthesis that will be familiar to long-time Farnam Street readers. The book is almost impossible to summarize given the multitude of ideas presented. But then again, most great books are. (Dig deeper into this amazing read here, here, and here.)

15. Becoming Wise: An Inquiry into the Mystery and Art of Living — A refreshing signal in world of noise that should be read and immediately re-read. There is so much goodness in here that scarcely will you find more than a page or two in my copy without a mark, bent page, or highlight. The entire book offers texture to thoughts you knew you had but didn't know how to express.

16. The Happiness Trap: How to Stop Struggling and Start Living
The way most of us search for and attempt to hold onto fleeting moments of happiness ends up ensuring that we’re miserable. A great practical book on developing mindfulness, which is so important in many aspects of your life, including satisfaction. Might be the best self-help book I’ve read.

 

 

The Island of Knowledge: Science and the Meaning of Life

“As the Island of Knowledge grows, so do the shores of our ignorance—the boundary between the known and unknown. Learning more about the world doesn't lead to a point closer to a final destination—whose existence is nothing but a hopeful assumption anyways—but to more questions and mysteries. The more we know, the more exposed we are to our ignorance, and the more we know to ask.”

***

Common across human history is our longing to better understand the world we live in, and how it works. But how much can we actually know about the world?

In his book, The Island of Knowledge: The Limits of Science and the Search for Meaning, Physicist Marcelo Gleiser traces our progress of modern science in the pursuit to the most fundamental questions on existence, the origin of the universe, and the limits of knowledge.

What we know of the world is limited by what we can see and what we can describe, but our tools have evolved over the years to reveal ever more pleats into our fabric of knowledge. Gleiser celebrates this persistent struggle to understand our place in the world and travels our history from ancient knowledge to our current understanding.

While science is not the only way to see and describe the world we live in, it is a response to the questions on who we are, where we are, and how we got here. “Science speaks directly to our humanity, to our quest for light, ever more light.

To move forward, science needs to fail, which runs counter to our human desire for certainty. “We are surrounded by horizons, by incompleteness.” Rather than give up, we struggle along a scale of progress. What makes us human is this journey to understand more about the mysteries of the world and explain them with reason. This is the core of our nature.

While the pursuit is never ending, the curious journey offers insight not just into the natural world, but insight into ourselves.

“What I see in Nature is a magnificent structure that we can comprehend only
very imperfectly,
and that must fill a thinking person with a feeling of humility.”
— Albert Einstein

We tend to think that what we see is all there is — that there is nothing we cannot see. We know it isn't true when we stop and think, yet we still get lulled into a trap of omniscience.

Science is thus limited, offering only part of the story — the part we can see and measure. The other part remains beyond our immediate reach.

What we see of the world,” Gleiser begins, “is only a sliver of what's out there.”

There is much that is invisible to the eye, even when we augment our sensorial perception with telescopes, microscopes, and other tools of exploration. Like our senses, every instrument has a range. Because much of Nature remains hidden from us, our view of the world is based only on the fraction of reality that we can measure and analyze. Science, as our narrative describing what we see and what we conjecture exists in the natural world, is thus necessarily limited, telling only part of the story. … We strive toward knowledge, always more knowledge, but must understand that we are, and will remain, surrounded by mystery. This view is neither antiscientific nor defeatist. … Quite the contrary, it is the flirting with this mystery, the urge to go beyond the boundaries of the known, that feeds our creative impulse, that makes us want to know more.

While we may broadly understand the map of what we call reality, we fail to understand its terrain. Reality, Gleiser argues, “is an ever-shifting mosaic of ideas.”

However…

The incompleteness of knowledge and the limits of our scientific worldview only add to the richness of our search for meaning, as they align science with our human fallibility and aspirations.

What we call reality is a (necessarily) limited synthesis. It is certainly our reality, as it must be, but it is not the entire reality itself:

My perception of the world around me, as cognitive neuroscience teaches us, is synthesized within different regions of my brain. What I call reality results from the integrated sum of countless stimuli collected through my five senses, brought from the outside into my head via my nervous system. Cognition, the awareness of being here now, is a fabrication of a vast set of chemicals flowing through myriad synaptic connections between my neurons. … We have little understanding as to how exactly this neuronal choreography engenders us with a sense of being. We go on with our everyday activities convinced that we can separate ourselves from our surroundings and construct an objective view of reality.

The brain is a great filtering tool, deaf and blind to vast amounts of information around us that offer no evolutionary advantage. Part of it we can see and simply ignore. Other parts, like dust particles and bacteria, go unseen because of limitations of our sensory tools.

As the Fox said to the Little Prince in Antoine de Saint-Exupery's fable, “What is essential is invisible to the eye.” There is no better example than oxygen.

Science has increased our view. Our measurement tools and instruments can see bacteria and radiation, subatomic particles and more. However precise these tools have become, their view is still limited.

There is no such thing as an exact measurement. Every measurement must be stated within its precision and quoted together with “error bars” estimating the magnitude of errors. High-precision measurements are simply measurements with small error bars or high confidence levels; there are no perfect, zero-error measurements.

[…]

Technology limits how deeply experiments can probe into physical reality. That is to say, machines determine what we can measure and thus what scientists can learn about the Universe and ourselves. Being human inventions, machines depend on our creativity and available resources. When successful, they measure with ever-higher accuracy and on occasion may also reveal the unexpected.

“All models are wrong, some are useful.”
— George Box

What we know about the world is only what we can detect and measure — even if we improve our “detecting and measuring” as time goes along. And thus we make our conclusions of reality on what we can currently “see.”

We see much more than Galileo, but we can't see it all. And this restriction is not limited to measurements: speculative theories and models that extrapolate into unknown realms of physical reality must also rely on current knowledge. When there is no data to guide intuition, scientists impose a “compatibility” criterion: any new theory attempting to extrapolate beyond tested ground should, in the proper limit, reproduce current knowledge.

[…]

If large portions of the world remain unseen or inaccessible to us, we must consider the meaning of the word “reality” with great care. We must consider whether there is such a thing as an “ultimate reality” out there — the final substrate of all there is — and, if so, whether we can ever hope to grasp it in its totality.

[…]

We thus must ask whether grasping reality's most fundamental nature is just a matter of pushing the limits of science or whether we are being quite naive about what science can and can't do.

Here is another way of thinking about this: if someone perceives the world through her senses only (as most people do), and another amplifies her perception through the use of instrumentation, who can legitimately claim to have a truer sense of reality? One “sees” microscopic bacteria, faraway galaxies, and subatomic particles, while the other is completely blind to such entities. Clearly they “see” different things and—if they take what they see literally—will conclude that the world, or at least the nature of physical reality, is very different.

Asking who is right misses the point, although surely the person using tools can see further into the nature of things. Indeed, to see more clearly what makes up the world and, in the process to make more sense of it and ourselves is the main motivation to push the boundaries of knowledge. … What we call “real” is contingent on how deeply we are able to probe reality. Even if there is such thing as the true or ultimate nature of reality, all we have is what we can know of it.

[…]

Our perception of what is real evolves with the instruments we use to probe Nature. Gradually, some of what was unknown becomes known. For this reason, what we call “reality” is always changing. … The version of reality we might call “true” at one time will not remain true at another. … Given that our instruments will always evolve, tomorrow's reality will necessarily include entitles not known to exist today. … More to the point, as long as technology advances—and there is no reason to suppose that it will ever stop advancing for as long as we are around—we cannot foresee an end to this quest. The ultimate truth is elusive, a phantom.

Gleiser makes his point with a beautiful metaphor. The Island of Knowledge.

Consider, then, the sum total of our accumulated knowledge as constituting an island, which I call the “Island of Knowledge.” … A vast ocean surrounds the Island of Knowledge, the unexplored ocean of the unknown, hiding countless tantalizing mysteries.

The Island of Knowledge grows as we learn more about the world and ourselves. And as the island grows, so too “do the shores of our ignorance—the boundary between the known and unknown.”

Learning more about the world doesn't lead to a point closer to a final destination—whose existence is nothing but a hopeful assumption anyways—but to more questions and mysteries. The more we know, the more exposed we are to our ignorance, and the more we know to ask.

As we move forward we must remember that despite our quest, the shores of our ignorance grow as the Island of Knowledge grows. And while we will struggle with the fact that not all questions will have answers, we will continue to progress. “It is also good to remember,” Gleiser writes, “that science only covers part of the Island.”

Richard Feynman has pointed out before that science can only answer the subset of question that go, roughly, “If I do this, what will happen?” Answers to questions like Why do the rules operate that way? and Should I do it? are not really questions of scientific nature — they are moral, human questions, if they are knowable at all.

There are many ways of understanding and knowing that should, ideally, feed each other. “We are,” Gleiser concludes, “multidimensional creatures and search for answers in many, complementary ways. Each serves a purpose and we need them all.”

“The quest must go on. The quest is what makes us matter: to search for more answers, knowing that the significant ones will often generate surprising new questions.”

The Island of Knowledge is a wide-ranging tour through scientific history from planetary motions to modern scientific theories and how they affect our ideas on what is knowable.
