My favorite books to rationally investigate mystical and psychotic experience

Why am I passionate about this?

My research into the overlap between mysticism and schizophrenia has garnered one academic monograph on James Joyce, with another on Charlie Kaufman’s films and fiction due out in 2025 (both from Routledge). For 15 years, I’ve been a writing professor at New York University, and the two things I want to impart to my students are: 1) the courage to pursue a singular question or unique viewpoint and (2) the compassion to write clearly for the reader! All five books on my list don’t shy away from profound questions of what it is to be a complex spiritual being, but they always remain lucid and engaging for a general audience.

James Joyce's Mandala

By Colm O'Shea,

Book cover of James Joyce's Mandala

What is my book about?

My book started life as a Ph.D. dissertation, but don’t let that put you off. After reading one dry-as-bones dissertation after another, I wanted to produce something readable and engaging that I could share with my friends, none of whom are academics. My initial question was: why is there so much geometric imagery in James Joyce’s work, especially in his final masterpiece, Finnegans Wake? 

There’s a rich tradition of mystics using sacred geometry (mandalas) throughout history and in every culture. The psychologist Carl Jung noticed that mandalas were also produced by schizophrenics in the 19th and 20th centuries. My book investigates the overlap between the twin poles of the mandala, what I call the “mystic and morbid” aspects of this mysterious entity.

The books I picked & why

Book cover of The Discovery of the Art of the Insane

Colm O'Shea Why did I love this book?

MacGregor’s book blew my mind when I first read it. This masterful history reveals the discovery of a secret treasure, one that eventually transformed the art world.

In the 19th and 20th centuries, mental asylums in Europe began experimenting with art therapy, allowing psychotic inmates access to drawing materials. Over seventeen chapters jam-packed with astounding images, MacGregor’s book tracks the evolution of what is now known as Outsider art and the profound effect it had (and continues to have) on avant-garde art.

I love MacGregor’s ability to marry the rigor of a scholar with a humane and sensitive commentary on the lives of these forgotten "schizophrenic masters.” This book inspired my own research into schizophrenic art and is my go-to source for inspiration on this theme. 

By John M. MacGregor,

Why should I read it?

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

What is this book about?

This pioneering work, the first history of the art of the insane, scrutinizes changes in attitudes toward the art of the mentally ill from a time when it was either ignored or ridiculed, through the era when major figures in the art world discovered the extraordinary power of visual statements by psychotic artists such as Adolf Wlfli and Richard Dadd. John MacGregor draws on his dual training in art history and in psychiatry and psychoanalysis to describe not only this evolution in attitudes but also the significant influence of the art of the mentally ill on the development of modern…


Book cover of Rational Mysticism: Spirituality Meets Science in the Search for Enlightenment

Colm O'Shea Why did I love this book?

It’s rare to find someone who writes engagingly about science and even rarer to find someone who is curious about the relationship between science and mysticism; the two realms are often considered to be unrelated, if not wholly incompatible.

John Horgan somehow manages to fuse the skepticism of a science journalist (which he is) with the open-mindedness of a spiritual seeker. I was delighted by his prose, which is detached enough to be fair to the mystics he interviews, but also confessional enough about his doubts and cynicism to win my trust.

Horgan’s odyssey to meet the high-profile mystical thinkers of the early 21st century stimulated me intellectually, but I often found myself moved by the simple humanity of its question: why do we exist? 

By John Horgan,

Why should I read it?

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

What is this book about?

John Horgan, author of the best-selling The End of Science, chronicles the most advanced research into the mechanics—and meaning—of mystical experiences. How do trances, visions, prayer, satori, and other mystical experiences “work”? What induces and defines them? Is there a scientific explanation for religious mysteries and transcendent meditation? John Horgan investigates a wide range of fields — chemistry, neuroscience, psychology, anthropology, theology, and more — to narrow the gap between reason and mystical phenomena. As both a seeker and an award-winning journalist, Horgan consulted a wide range of experts, including theologian Huston Smith, spiritual heir to Joseph Campbell; Andrew Newberg,…


Book cover of Contemporary Psychoanalysis and Eastern Thought

Colm O'Shea Why did I love this book?

John Suler is a prodigious writer of academic books, but that’s not what impresses me. Instead, what I love is to read prose that can take dense subject matter and make it accessible to the general reader.

When I was trying to reconcile my own research into Eastern mysticism with Western-oriented approaches to psychology, I found Suler’s work to be the Rosetta Stone I urgently needed to make sense of the impasse.

It’s like having a knowledgeable but personable mentor teaching you how to translate from one “language” about consciousness into another.

Why should I read it?

1 author picked Contemporary Psychoanalysis and Eastern Thought as one of their favorite books, and they share why you should read it.

What is this book about?

This book explores the convergence of psychoanalysis and Asian thought. It explores key theoretical issues. What role does paradox play in psychological transformations? How can the oriental emphasis on attaining "no-self" be reconciled with the western emphasis on achieving an integrated self? The book also inquires into pragmatic questions concerning the nature of psychological change and the practice of psychotherapy. The Taoist I Ching is explored as a framework for understanding the therapeutic process. Principles from martial arts philosophy and strategy are applied to clinical work.

Combining theoretical analyses, case studies, empirical data, literary references, and anecdotes, this book is…


Book cover of Nonduality: In Buddhism and Beyond

Colm O'Shea Why did I love this book?

The problem with a lot of academic philosophy is that it can feel overly cerebral or divorced from any urgent sense of the common suffering of mankind.

What I admire about David Loy’s work is that, despite his incredible erudition about languages and religions, he speaks from the heart about the need for a spiritual path that is accessible to everyone.

Like John Suler, I value Loy as a cultural translator; he effortlessly makes the insights of Eastern and Western philosophy legible in such a way that I feel less alone in the world.

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

What is this book about?

One of Western Buddhism’s most sophisticated thinkers on one of Buddhism’s most central topics.

The concept of nonduality lies at the very heart of Mahayana Buddhism. In the West, it’s usually associated with various kinds of absolute idealism in the West, or mystical traditions in the East—and as a result, many modern philosophers are poorly informed on the topic. Increasingly, however, nonduality is finding its way into Western philosophical debates. In this “scholarly but leisurely and very readable” (Spectrum Review) analysis of the philosophies of nondualism of (Hindu) Vedanta, Mahayana Buddhism, and Taoism, renowned thinker David R. Loy extracts what…


Book cover of Architecture, Mysticism and Myth

Colm O'Shea Why did I love this book?

This is the oldest book on my list, and I worry that readers might dismiss Lethaby as some kind of dusty artifact from a bygone era. I stumbled on his work by accident when I was researching architectural ideas as they related to spiritual concepts.

I’d never heard of Lethaby, but once I started reading his work, I read it through in one (albeit long) sitting. Why? His imaginative grasp of the ancient minds that devised the earliest models of the heavens and who designed temples and homes to reflect those beliefs is a joyous and thrilling tour of the human spirit.

It’s a travesty to me that Lethaby isn’t a household name like William Morris.

Kathleen DuVal Author Of Independence Lost: Lives on the Edge of the American Revolution

New book alert!

Why am I passionate about this?

I’m a professional historian and life-long lover of early American history. My fascination with the American Revolution began during the bicentennial in 1976, when my family traveled across the country for celebrations in Williamsburg and Philadelphia. That history, though, seemed disconnected to the place I grew up—Arkansas—so when I went to graduate school in history, I researched in French and Spanish archives to learn about their eighteenth-century interactions with Arkansas’s Native nations, the Osages and Quapaws. Now I teach early American history and Native American history at UNC-Chapel Hill and have written several books on how Native American, European, and African people interacted across North America.

Native Nations: A Millennium in North America

By Kathleen DuVal,

What is this book about?

Long before the colonization of North America, Indigenous Americans built diverse civilizations and adapted to a changing world in ways that reverberated globally. And, as award-winning historian Kathleen DuVal vividly recounts, when Europeans did arrive, no civilization came to a halt because of a few wandering explorers, even when the strangers came well armed.

A millennium ago, North American cities rivaled urban centers around the world in size. Then, following a period of climate change and instability, numerous smaller nations emerged, moving away from rather than toward urbanization. From this urban past, egalitarian government structures, diplomacy, and complex economies spread…
