Haywood's book list on critical thinking books for the intellectually curious

Haywood Spangler Why Haywood loves this book

I find this book answers questions many people ask: Why aren’t we always logical? What gets in the way of our making effective decisions?

I first read this book when I started my consulting practice and realized I needed to combine psychology with philosophy in teaching critical thinking in professional settings. People want to understand why we can be unreasonable in the first place. Kahneman’s book helped me improve my own thinking, making me aware of the ways my previous experiences quickly provide interpretations of new experiences.

I find the ability to “hit the pause button” regarding my response to a specific situation and to ask myself, “Is my immediate, intuitive response useful or misleading me?” is one of my most important insights from this book.

Book cover of The Robot's Rebellion: Finding Meaning in the Age of Darwin

Marianne Talbot Author Of Critical Reasoning: A Romp through the Foothills of Logic for the Complete Beginner

From my list on to learn how to argue well better.

Why am I passionate about this?

I taught philosophy (in particular critical reasoning!) for the colleges of Oxford University between 1987 and 2021. But, aged 15, I was thrown out of school (for truancy and disruption). Between the ages of 18 and 23 I travelled the world, hitch-hiking through Asia, living in Australasia, then travelling back through Africa. By the time I got home, starved of intellectual stimulation, I started an Open University Course and discovered logic. It was the hardest thing I had ever done. But also the most enjoyable. I loved getting to grips with difficult distinctions and concepts and having to use them precisely. Getting the answers right felt like an achievement. Getting them wrong, a challenge. I’ve loved logic ever since!

Marianne Talbot Why Marianne loves this book

Stanovich takes his title from the very last sentence in Richard Dawkin’s book The Selfish Gene, “We, alone on earth, can rebel against the tyranny of the selfish replicators.” In his book, Stanovich shows how human beings are able to rebel against those selfish replicators – our genes. It involves exercising, in Kahneman’s terminology, our ‘system two’ and exercising tenacity and self-discipline in bringing to bear logic and rationality in our decisions. This book is not an easy read, but it is a fascinating account of why human thinking is different and of what such differences might in principle enable us to do.

What is this book about?

The idea that we might be robots is no longer the stuff of science fiction; decades of research in evolutionary biology and cognitive science have led many esteemed thinkers and scientists to the conclusion that, following the precepts of universal Darwinism, humans are merely the hosts for two replicators (genes and memes) that have no interest in us except as conduits for replication. Accepting and now forcefully responding to this disturbing idea that precludes the possibilities of morality or free will, among other things, Keith Stanovich here provides the tools for the "robot's rebellion," a program of cognitive reform necessary…

Marianne Talbot Why Marianne loves this book

In this book, David-Hillel Ruben introduces the ways in which various philosophers have tried to explain the concept of explanation, before ending with his own account of explanation. Explaining is one of the most important actions a human being can engage in. Diagnoses, for example, are explanations of why you have the symptoms you have, or perhaps they are explanations of why that bridge collapsed or why those people bombed that mosque. In trying to explain something we make our first attempts at trying to understand the phenomenon under investigation. But what actually is an explanation? What do we do when we try to explain something. This is not an easy read, but it is an excellent book.

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

What is this book about?

This book introduces readers to the topic of explanation. The insights of Plato, Aristotle, J.S. Mill and Carl Hempel are examined, and are used to argue against the view that explanation is merely a problem for the philosophy of science. Having established its importance for understanding knowledge in general, the book concludes with a bold and original explanation of explanation.

Book cover of Tetralogue: I'm Right, You're Wrong

Gordon Barnes Author Of How Do You Know? A Dialogue

From my list on philosophy written as engaging dialogues.

Why am I passionate about this?

I am Associate Professor of Philosophy at the State University of New York at Brockport. I have been teaching and writing philosophy for over 20 years. I have published articles in professional journals on a wide range of subjects, from epistemology to philosophy of religion and political philosophy. I think that philosophy, at its best, is a good conversation, in which people give reasons for their views, and listen to others give reasons for theirs. That’s the best way for human beings to think about philosophical questions. That’s why I love philosophical dialogues—they do philosophy in a way that embodies what philosophy is, at its very best.

Gordon's book list on philosophy written as engaging dialogues

Gordon Barnes Why Gordon loves this book

This book grabs your attention right from the start. Four people are on a train, and one of them believes in witches. That’s crazy, right? (The witches part, not the train part.) But can you prove that he is wrong? One character trusts science, and only science. Another is a relativist, who believes that each person’s opinion is “true for them.” And then there is the annoying young philosopher, who is just as irritating as she is logical. This is a great book about truth, knowledge, fallibility, and tolerance. Timothy Williamson is one of the best philosophers alive today, and yet this book is accessible and engaging for anyone who wants to think about fundamental questions. The characters are compelling, and the writing is witty and fun.

2 authors picked Tetralogue as one of their favorite books, and they share why you should read it.

What is this book about?

Four people with radically different outlooks on the world meet on a train and start talking about what they believe. Their conversation varies from cool logical reasoning to heated personal confrontation. Each starts off convinced that he or she is right, but then doubts creep in.

In a tradition going back to Plato, Timothy Williamson uses a fictional conversation to explore questions about truth and falsity, and knowledge and belief. Is truth always relative to a point of view? Is every opinion fallible? Such ideas have been used to combat dogmatism and intolerance, but are they compatible with taking each…


Book cover of Essentials of Scientific Research: A Practical Guide

Martín López Corredoira Author Of Against the Tide: A Critical Review by Scientists of How Physics and Astronomy Get Done

From my list on mainstream science as monopoly of truth.

Why am I passionate about this?

As a professional, scientific researcher in astrophysics and philosopher, I have been observing many unfair situations in science: hard-working, talented scientists with bright and challenging ideas who get no attention and bureaucrats or administrators of science (I call them “astropolitics” within my field of research) who have no talent, have neither time nor interest to think about science, and however are visible as the most eminent scientists of our time.

Martín's book list on mainstream science as monopoly of truth

Martín López Corredoira Why Martín loves this book

This is a good attempt to teach some rules on how to survive as a scientist under the miseries of scientific research nowadays. I agree with many of his conclusions: integrity and freedom in science are not usual in academia, and one has to be away from official centers to develop creativity and innovative dissenting ideas or otherwise suffer brainwashing, politicization, social conflict, and ostracism.

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

What is this book about?

Despite its technical sophistication, scientific research often has flaws in procedure, logic, and language that undermine its value. In Essentials of Scientific Research, Devon D. Brewer covers indispensable principles and practices for conducting sound scientific research that are rarely taught or mentioned in textbooks. These frequently overlooked principles and practices are based on common sense and logic. In this book, Brewer focuses on four aspects of doing scientific research: steps and procedures common to all fields, communicating research, working and interacting with others in scientific settings, and intellectual and ethical matters. Brewer highlights the timeless nature of the Essentials with…


Book cover of Author Unknown: On the Trail of Anonymous

James E. Crisp Author Of Sleuthing the Alamo: Davy Crockett's Last Stand and Other Mysteries of the Texas Revolution

From my list on history books written from hidden, elusive, and mysterious sources.

Why am I passionate about this?

I am passionate about bringing back to life persons from the past who have been forgotten, misunderstood, or even deliberately mischaracterized. In order to get to the truth, there are a host of myths that must be shattered or discarded. Most of the histories that I have written have done precisely this–showing the fallacy of familiar myths and discovering the hidden truths about people and events that have been distorted, often by some of the most popular literature. In order to achieve these results, I have had to spend years in “boring” archives in order to reveal people and events that are never boring.

James E. Crisp Why James loves this book

I was fascinated by Foster’s detective work in literary history–searching for the actual authors of poems, political novels, and proclamations, the authors of which had always been considered “anonymous.” Using a variety of ingenious methods, Foster tracks down the persons behind mysterious documents ranging from the Unabomber’s threats to “The Night Before Christmas.”

I loved Foster’s wry and sometimes caustic sense of humor, especially when he is skewering the “experts” whom he proves to be wrong. This book is, quite simply, great fun for the intellectually curious.

Book cover of The Seven Deadly Sins of Psychology: A Manifesto for Reforming the Culture of Scientific Practice

Rick Szostak Author Of Integrating the Human Sciences: Enhancing Progress and Coherence across the Social Sciences and Humanities

From my list on reforming the social sciences and humanities.

Why am I passionate about this?

I am proud to be a human (social) scientist but think that we could collectively achieve a much more successful human science enterprise. And I believe that a better human science would translate into better public policy. Most human scientists focus on their own research, paying little attention to how the broader enterprise functions. I have written many works of a methodological nature over the years. I am pleased to point here to a handful of works with sound advice for enhancing the human science enterprise.

Rick's book list on reforming the social sciences and humanities

Rick Szostak Why Rick loves this book

Though this book focuses on psychology, it has lessons for all social sciences.

Chambers, like me, is critical of certain practices and yet deeply respectful of what has been accomplished. He devotes much of his attention to the problem of confirmation bias. We as humans are more likely to accept results that conform to prior beliefs.

Journals are also more likely to publish such results. Scholars play with their findings, adding or removing data points to achieve a target level of statistical significance. The result is that we are often more confident in scholarly consensus than we should be. Chambers explains complex ideas clearly, and is passionate about the need for reform.

Why psychology is in peril as a scientific discipline-and how to save it

Psychological science has made extraordinary discoveries about the human mind, but can we trust everything its practitioners are telling us? In recent years, it has become increasingly apparent that a lot of research in psychology is based on weak evidence, questionable practices, and sometimes even fraud. The Seven Deadly Sins of Psychology diagnoses the ills besetting the discipline today and proposes sensible, practical solutions to ensure that it remains a legitimate and reliable science in the years ahead. In this unflinchingly candid manifesto, Chris Chambers shows how…


Book cover of Laboratory Life: The Construction of Scientific Facts

Michael Strevens Author Of The Knowledge Machine: How Irrationality Created Modern Science

From my list on show how science really works.

Why am I passionate about this?

I almost became a scientist. But something about my undergraduate physics labs—could it be that none of my measurements came out right?—didn't quite grab me, and I found myself, by the time I earned my degree, an observer of science instead. I was just as fascinated with fundamental particles, the origin of life, and artificial intelligence as before, but now I was doing the philosophy, history, and sociology of science. You might even call it the science of science. So perhaps I became a scientist after all, but one intent on the question of how science works and why it works so well.

Michael's book list on show how science really works

Michael Strevens Why Michael loves this book

I’m always talking to scientists, but I have never undertaken anything like Bruno Latour’s voyage of ethnographic discovery. He decided to figure out how science works by embedding himself in a scientific lab for two years and, discarding all preconceptions, recording what he saw there as though he were an anthropologist visiting a foreign culture.

It turns out to be an intensely political culture: rather than following prescribed laws of method and logic, scientists are making judgment calls and negotiating with one another to decide the significance of their data, making it up as they go along. Latour brings out the subjectivity of much low-level scientific decision-making, in contrast to Kuhn’s picture, in which the blueprint for thinking—the paradigm—rules over the enterprise like a catechism.

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

What is this book about?

This highly original work presents laboratory science in a deliberately skeptical way: as an anthropological approach to the culture of the scientist. Drawing on recent work in literary criticism, the authors study how the social world of the laboratory produces papers and other "texts,"' and how the scientific vision of reality becomes that set of statements considered, for the time being, too expensive to change. The book is based on field work done by Bruno Latour in Roger Guillemin's laboratory at the Salk Institute and provides an important link between the sociology of modern sciences and laboratory studies in the…

From my list on empower women and navigate workplace realities.

Why am I passionate about this?

As an attorney, former TV broadcaster, and workplace consultant, I’ve devoted my career to empowering women and confronting systemic inequities. My passion stems from personal experience navigating the complexities of workplace harassment, which inspired me to write my book and guide others through similar challenges. I am continually drawn to books that illuminate the hidden power structures and offer practical tools for resilience, empowerment, and self-advocacy. The works on this list have profoundly shaped my perspective, providing inspiration and clarity in both my professional and personal journey. I hope they resonate with you as deeply as they have with me.

Adrienne Lawrence Why Adrienne loves this book

This book completely reframed how I see the world. Perez dives into the pervasive gender data gaps that impact everything from workplace policies to public health. Her meticulous research and compelling examples made me realize how much of our world is designed without women in mind. It’s equal parts infuriating and enlightening, and it left me determined to question systems that perpetuate inequality.

This book is a must-read for anyone who wants to understand the hidden ways gender bias shapes our lives.

Winner of the 2019 Royal Society Science Book Prize

Data is fundamental to the modern world. From economic development, to healthcare, to education and public policy, we rely on numbers to allocate resources and make crucial decisions. But because so much data fails to take into account gender, because it treats men as the default and women as atypical, bias and discrimination are baked into our systems. And women pay tremendous costs for this bias, in time, money, and often with their lives.

Book cover of The Logic of Scientific Discovery

James L. Sherley Author Of Missing Elements in the Public Science Supporting the COVID-19 Spread Narrative in the US

From my list on what science and scientists are really all about.

Why am I passionate about this?

A childhood friend says that I am the only person he knows who grew up to be exactly what he said he wanted to become. But he is mistaken because I was born a scientist. I have no memories when I was not thinking about science, learning it, doing it, teaching it, trying to improve it, pondering it, or sharing it with others. Over my life and career as a scientist, I have been further fulfilled by undergirding my scientific work with reflection and introspection through reading the history, philosophy, and practice of science revealed and disclosed in books like the five I recommend here. Enjoy them as I have!

James' book list on what science and scientists are really all about

James L. Sherley Why James loves this book

I don’t remember how this book made it into my hands, but I am so glad it did! This book has made me a better scientist because it taught me scientific humility. Popper rips apart the very fabric of experimental science’s unique and most powerful tool, the scientific method.

When I taught students at MIT how to apply experimental analysis with the scientific method to establish that an observed effect was, in fact, caused by an identified factor, always in my head, I would hear the words of Popper. Past relationships between factors and effects are not necessarily maintained in the future. This understanding of the nature of the universe reveals the imperfections of science, which rarely proves the world’s truths but often does elucidate them.

What is this book about?

Described by the philosopher A.J. Ayer as a work of 'great originality and power', this book revolutionized contemporary thinking on science and knowledge. Ideas such as the now legendary doctrine of 'falsificationism' electrified the scientific community, influencing even working scientists, as well as post-war philosophy. This astonishing work ranks alongside The Open Society and Its Enemies as one of Popper's most enduring books and contains insights and arguments that demand to be read to this day.
