Book cover of Quantum Computing Since Democritus

Ran Spiegler Author Of The Curious Culture of Economic Theory

From my list on scholarly and popular-science books that both pros and amateurs can enjoy.

Why am I passionate about this?

I am an academic researcher and an avid non-fiction reader. There are many popular books on science or music, but it’s much harder to find texts that manage to occupy the space between popular and professional writing. I’ve always been looking for this kind of book, whether on physics, music, AI, or math – even when I knew that as a non-pro, I wouldn’t be able to understand everything. In my new book I’ve been trying to accomplish something similar: A book that can intrigue readers who are not professional economic theorists, that they will find interesting even if they can’t follow everything.

Ran Spiegler Why did Ran love this book?

A simple (not perfect) test of whether you’re going to love this book: Just check out the author’s blog, called “shtetl-optimized”. The style is similar: sharp, funny, mixing professional theoretical Computer Science with broader takes.

I am still in the middle of the book, and nevertheless, I’m happy to recommend it. As an amateur with superficial CS knowledge, I am enjoying this introduction to classical complexity theory and the basic theory of quantum computation.

Aaronson’s distinctive style makes the ride all the more enjoyable. It’s neither a “real” textbook nor a pop-science book. It’s in a weird space somewhere in between, and I love it!

Why should I read it?

3 authors picked Quantum Computing Since Democritus as one of their favorite books, and they share why you should read it.

What is this book about?

Written by noted quantum computing theorist Scott Aaronson, this book takes readers on a tour through some of the deepest ideas of maths, computer science and physics. Full of insights, arguments and philosophical perspectives, the book covers an amazing array of topics. Beginning in antiquity with Democritus, it progresses through logic and set theory, computability and complexity theory, quantum computing, cryptography, the information content of quantum states and the interpretation of quantum mechanics. There are also extended discussions about time travel, Newcomb's Paradox, the anthropic principle and the views of Roger Penrose. Aaronson's informal style makes this fascinating book accessible…


Book cover of Synthetic Philosophy of Contemporary Mathematics

Rocco Gangle Author Of Diagrammatic Immanence: Category Theory and Philosophy

From my list on mathematics for the philosophically inclined.

Why am I passionate about this?

Philosophy’s core questions have always obsessed me: What is real? What makes life worth living? Can knowledge be made secure? In graduate school at the University of Virginia I was drawn to mathematically formalized approaches to such questions, especially those of C. S. Peirce and Alain Badiou. More recently, alongside colleagues at Endicott College’s Center for Diagrammatic and Computational Philosophy and GCAS College Dublin I have explored applications of diagrammatic logic, category theory, game theory, and homotopy type theory to such problems as abductive inference and artificial intelligence. Philosophers committed to the perennial questions have much to gain today from studying the new methods and results of contemporary mathematics.

Rocco's book list on mathematics for the philosophically inclined

Rocco Gangle Why did Rocco love this book?

Zalamea’s book is the perfect introduction and survey if you want to understand how developments in contemporary mathematics are relevant to current philosophy.

Zalamea’s own approach follows closely in the steps of Peirce, Lautman, and Grothendieck, merging pragmatism, dialectics, and sheaf theory, but he also engages the work of dozens of other key mathematicians and philosophers coming from different points of view, sometimes cursorily, always tantalizingly.

No philosopher can read this book without a quickened heartbeat and eager plans to clear shelf space for some of the many volumes of mathematics and philosophy of mathematics canvassed here by Zalamea.

What is this book about?

A panoramic survey of the vast spectrum of modern and contemporary mathematics and the new philosophical possibilities they suggest.

A panoramic survey of the vast spectrum of modern and contemporary mathematics and the new philosophical possibilities they suggest, this book gives the inquisitive non-specialist an insight into the conceptual transformations and intellectual orientations of modern and contemporary mathematics.

The predominant analytic approach, with its focus on the formal, the elementary and the foundational, has effectively divorced philosophy from the real practice of mathematics and the profound conceptual shifts in the discipline over the last century. The first part discusses the…

Rocco's book list on mathematics for the philosophically inclined

Rocco Gangle Why did Rocco love this book?

From a strictly philosophical perspective, the emergence of category theory as a unifying paradigm rivaling set theory is probably the most important development in mathematics in the last half-century.

But for philosophers without a lot of mathematical background, learning even its rudiments can be daunting. Among many introductory texts (Lawvere and Schanuel, Awodey, Riehl, Spivak), Cheng’s book stands out as perhaps the friendliest and most accessible.

She does not forego rigor, but she isn’t afraid to put aside precise formalism when necessary for intuition and clearer understanding. Her book takes the reader from mathematical beginnings through category theory’s core constructions to glimpses of higher-order categories (one of Cheng’s areas of expertise).

A mathematically novice philosopher who wants to understand the basics of category theory couldn’t do better.

Rocco's book list on mathematics for the philosophically inclined

Rocco Gangle Why did Rocco love this book?

Far too many math books are written in a style so terse and ungenerous that all but the most mathematically gifted readers hardly have a fair chance of understanding.

On the other hand, the discursive style of much philosophy of mathematics gains readability at the expense of formal rigor. Button and Walsh strike the perfect balance in this exceptionally rich introduction to model theory from a distinctively philosophical perspective.

There’s no getting around the fact that the mathematics of model theory is hard going. But this book works through all the relevant proofs in clear and detailed terms (no lazy “we leave this as an exercise for the reader”), and the authors are always careful to motivate each section with well-chosen philosophical concerns right up front.

An Everest, but worth it.

By Tim Button, Sean Walsh,

Why should I read it?

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

What is this book about?

Model theory is used in every theoretical branch of analytic philosophy: in philosophy of mathematics, in philosophy of science, in philosophy of language, in philosophical logic, and in metaphysics.
But these wide-ranging uses of model theory have created a highly fragmented literature. On the one hand, many philosophically significant results are found only in mathematics textbooks: these are aimed squarely at mathematicians; they typically presuppose that the reader has a serious background in mathematics; and little clue is given as to their philosophical significance. On the other hand, the philosophical applications of these results are scattered across disconnected pockets of…


Book cover of Proofs and Refutations

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?

Lots of people have a priori ideas about what mathematics is all about but Lakatos had the brilliant idea of looking at what actually happened. His book is all about one famous theorem: “for all regular polyhedra, V – E + F =2, where V is the number of vertices, E is the number of edges, and F is the number of faces.  Think of a cube where V=8, E = 12, F = 6.  

We tend to think that mathematics proceeds from a well-defined hypothesis to conclusion. But that is only the finishing step. Along the way the definitions keep changing as do the hypotheses and even the conclusion. Everything is moving! This is what makes doing mathematics so exciting!

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

What is this book about?

Imre Lakatos's Proofs and Refutations is an enduring classic, which has never lost its relevance. Taking the form of a dialogue between a teacher and some students, the book considers various solutions to mathematical problems and, in the process, raises important questions about the nature of mathematical discovery and methodology. Lakatos shows that mathematics grows through a process of improvement by attempts at proofs and critiques of these attempts, and his work continues to inspire mathematicians and philosophers aspiring to develop a philosophy of mathematics that accounts for both the static and the dynamic complexity of mathematical practice. With a…

Ian Stewart Author Of Flatterland: Like Flatland Only More So

From my list on to find out why math isn’t what you think.

Why am I passionate about this?

As a kid I read every popular math book I could lay my hands on. When I became a mathematician I wanted to do more than teaching and research. I wanted to tell everyone what a wonderful and vital subject math is. I started writing popular math books, and soon was up to my neck in radio, TV, news media, magazines... For 12 years I wrote the mathematical Recreations Column for Scientific American. I was only the second mathematician in 170 years to deliver the Royal Institution Christmas Lectures, on TV with a live tiger. The University changed my job description: half research, half ‘outreach’. I had my dream job.

Ian's book list on to find out why math isn’t what you think

Ian Stewart Why did Ian love this book?

Mathematicians are constantly baffled by the public’s lack of awareness, not just of what mathematics does, but what it is. Today’s technological society functions only because of a vast range of mathematical concepts, techniques, and discoveries, which go far beyond elementary arithmetic and algebra. This was one of the first books to tackle these misunderstandings head on. It does so by examining not just the math and what it’s used for, but the social structures, the ‘conditions of civilization’ that have brought us to this curious state: utterly dependent on math, almost universally unaware that we are.

According to Michael Schneider, "The universe may be a mystery, but it's no secret." This book is a comprehensive yet simple visual guide to understanding the hidden meaning in the mathematical composition of all physical form. It is fun and fascinating to discover the sacred geometry visible throughout nature, in flowers, crystals, plants, shells, and the human body. You don't have to be a mathematician to see the beauty and symmetry of these patterns in every expression of God's creation, once revealed.

Book cover of The Lives of Literature: Reading, Teaching, Knowing

Robert F. Barsky Author Of Clamouring for Legal Protection: What the Great Books Teach Us about People Fleeing from Persecution

From my list on to help us harness the ‘classics’ to address crises.

Why am I passionate about this?

I have taught a broad array of humanities and social sciences courses over the years, sometimes employing case studies from the realm of law, most notably stories about undocumented migrants, refugees, or homeless people. I’ve also had occasion to teach in law schools, usually in ways that bridge the gap between the legality of forced displacement, and the lived experiences of those who have done it. I won a Rockefeller Foundation grant to write my newest book, Clamouring for Legal Protection, in which I considered the idea that we can learn a lot about refugees and vulnerable migrants with references to people we know well: Ulysses, Dante, Satan, and even Alice in Wonderland.

Robert F. Barsky Why did Robert love this book?

Weinstein takes the age-old question – what is literature? – and transforms it into why we (would want to) read literature. For him, literature changes us, allows us to be someone else, and provides us insight into the world we inhabit, and many more worlds we haven’t. He reads a broad array of works, from Sophocles to James Joyce and Toni Morrison, and thinks about such issues as identification, empathy, and sympathy with those we come to ‘know’ through our reading.

Mixing passion and humor, a personal work of literary criticism that demonstrates how the greatest books illuminate our lives

Why do we read literature? For Arnold Weinstein, the answer is clear: literature allows us to become someone else. Literature changes us by giving us intimate access to an astonishing variety of other lives, experiences, and places across the ages. Reflecting on a lifetime of reading, teaching, and writing, The Lives of Literature explores, with passion, humor, and whirring intellect, a professor's life, the thrills and traps of teaching, and, most of all, the power of literature to lead us to…


Book cover of The Collapse of Chaos: Discovering Simplicity in a Complex World

Michael Edgeworth McIntyre Author Of Science, Music, and Mathematics: The Deepest Connections

From my list on to get you past selfish-gene theory.

Why am I passionate about this?

I’m a scientist at the University of Cambridge who’s worked on environmental research topics such as jet streams and the Antarctic ozone hole. I’ve also worked on solar physics and musical acoustics. And other branches of science have always interested me. Toward the end of my career, I became fascinated by cutting-edge issues in biological evolution and natural selection. Evolution is far richer and more complex than you’d think from its popular description in terms of ‘selfish genes’. The complexities are central to understanding deep connections between the sciences, the arts, and human nature in general, and the profound differences between human intelligence and artificial intelligence.

Michael's book list on to get you past selfish-gene theory

Michael Edgeworth McIntyre Why did Michael love this book?

It achieves an important and unusual cross-fertilization between two very different kinds of expertise. Both authors are highly innovative, and creative, thinkers, Cohen in biology and Stewart in mathematics.

Cohen is a biologist fascinated by the complexity observed in the living world, and Stewart is an expert on the mathematics of chaos and complexity. The result is a profound and multifaceted view of many natural phenomena, and of evolution in particular. It becomes very clear how selfish-gene theory fails to take account of important evolutionary mechanisms.

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

What is this book about?

Moving on from his books on chaos ("Does God Play Dice?") and symmetry ("Fearful Symmetry"), the author of this book deals with the wider field of complexity theory. The book tackles the question of how complexity arises in nature, of how life overcomes chaos and entropy to create developing order. Co-written with biologist Jack Cohen, the book will range across the central areas of modern science, from quantum mechanics and cosmology to evolution and intelligence, looking at the central questions of order, chaos, reductionism and complexity.
