Book cover of The World as Will and Representation, Vol. 1

Charles P. Webel Author Of The World as Idea: A Conceptual History

From my list on how the world may or may not be what you think it is.

Why am I passionate about this?

As a lifelong student with what I sometimes call “a multidisciplinary disorder,” I have been intrigued both about “the outer world,” or the “external environment of life on planet Earth, and “the mind that knows the world.” Hence, as a teenager in New York City, I read voraciously books in philosophy, history, and the social and natural sciences to learn what “great minds” have thought about “the world.” Much later, as an “academic” researcher and writer, I scoured the shelves of university libraries to examine what I considered the strengths and weaknesses of the academic disciplines that addressed our “knowledge of the world,” and their applications for “changing the world for the better.” My book The World as Idea is the first volume of a projected trilogy modestly entitled The Fate of This World and The Future of Humanity. I’m now working on the second volume, The Reality of This World.

Charles' book list on how the world may or may not be what you think it is

Charles P. Webel Why did Charles love this book?

Schopenhauer is one of the 19th century’s most important, and frequently overlooked, thinkers.

His multivolume work, translated as The World as Will and Representation, or The World as Will and Idea, has had the single greatest impact on my own thinking about “the world,” and as clearly written as a German philosopher can make it, this multi-volume, sometimes appearing as one-volume abridged edition, should be on every educated reader’s bucket list.

By Arthur Schopenhauer,

Why should I read it?

1 author picked The World as Will and Representation, Vol. 1 as one of their favorite books, and they share why you should read it.

What is this book about?

Arthur Schopenhauer's Die Welt als Wille und Vorstellung is one of the most important philosophical works of the nineteenth century, the basic statement of one important stream of post-Kantian thought. It is without question Schopenhauer's greatest work. Conceived and published before the philosopher was 30 and expanded 25 years later, it is the summation of a lifetime of thought.
For 70 years, the only unabridged English translation of this work was the Haldane-Kemp collaboration. In 1958, a new translation by E. F. J. Payne appeared that decisively supplanted the older one. Payne's translation is superior because it corrects nearly 1,000…


Book cover of You Are the Universe: Discovering Your Cosmic Self and Why It Matters

Larry Gottlieb Author Of Hoodwinked: Uncovering Our Fundamental Superstitions

From my list on to help us understand human being.

Why am I passionate about this?

As long as I can remember, I have wanted to understand how the universe works. I studied physics with a firm belief in scientific materialism, the belief that all things can or will be explained by science, including consciousness. However, after earning an advanced degree I found myself no closer to a satisfying answer to my inquiry into the relationship between consciousness and the physical world. Then, a personal experience of unembodied consciousness convinced me that my answers would have to come from a reexamination of all that I had believed, an internal journey over decades that has borne fruit in unexpected and magical ways.

Larry Gottlieb Why did Larry love this book?

Deepak Chopra has been exploring the relationship between spirituality and science for many decades, and Menas Kafatos’s peer-reviewed research on cosmology and astrophysics, among other topics, is well documented. Their work in this book makes it clear that instead of living in a material, unknowing and uncaring universe, we instead live in what they call a human universe, one that is living, conscious, and evolving. This book makes the case convincingly that we create our own reality in a conscious universe that responds to the beliefs and thoughts that reside in our minds. I have watched Mr. Chopra speak numerous times, and I appreciate his loving and gentle delivery. This book gave me a condensed and satisfying explanation of his worldview.

NEW YORK TIMES BESTSELLER • Deepak Chopra joins forces with leading physicist Menas Kafatos to explore some of the most important and baffling questions about our place in the world. 

"A riveting and absolutely fascinating adventure that will blow your mind wide open!" —Dr. Rudolph E. Tanzi
 
What happens when modern science reaches a crucial turning point that challenges everything we know about reality? In this brilliant, timely, and practical work, Chopra and Kafatos tell us that we've reached just such a point. In the coming era, the universe will be completely redefined as a "human universe" radically unlike the…


Book cover of Notes on Complexity: A Scientific Theory of Connection, Consciousness, and Being

Paul J. Mills Author Of Science, Being, & Becoming: The Spiritual Lives of Scientists

From my list on bridging the science and spirituality gap.

Why am I passionate about this?

I started practicing meditation while I was in high school and within 2 months of starting I had a metaphysical experience. That experience led me to become a scientist, I wanted to learn ways to study the spiritual using the methodologies of science. I've had a successful career with over 400 scientific publications and have had my work featured in the media and presented at hundreds of conferences and workshops around the world, including at the United Nations. Many scientists today are working to bridge the so-called gap between science and spirit and the positive effects they are having on increasing our understanding of what it is to be human.

Paul's book list on bridging the science and spirituality gap

Paul J. Mills Why did Paul love this book?

Dr. Neil Theise is a physician scientist whose been on a spiritual journey since childhood. A constant part of his explorations has been to understand how complex systems behave that illuminate the very nature of life itself, from quantum foam to single-celled organisms, to human beings, to entire ecosystems, and beyond.

In this book, Neil elegantly illuminates in clear and accessible prose the many surprising underlying connections within a universe that is itself one vast complex system. He takes us to the frontiers of human knowledge, where science meets philosophy and beyond.

He restores wonder to our experience of the every day, allowing us to approach the world with greater understanding and a renewed sense of meaning.

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

What is this book about?

An electrifying introduction to complexity theory, the science of how complex systems behave, that explains the interconnectedness of all things and that Deepak Chopra says, "will change the way you understand yourself and the universe."

Nothing in the universe is more complex than life. Throughout the skies, in oceans, and across lands, life is endlessly on the move. In its myriad forms-from cells to human beings, social structures, and ecosystems-life is open-ended, evolving, unpredictable, yet adaptive and self-sustaining. Complexity theory addresses the mysteries that animate science, philosophy, and metaphysics: how this teeming array of existence, from the infinitesimal to the…


Book cover of Event Factory

Chana Porter Author Of The Seep

From my list on to shock, expand, and engulf you.

Why am I passionate about this?

Writer and essayist Agnes Borinsky called my debut novel The Seep, A swift shock of a novel that has shifted how I see our world.Here are five short, urgent novels that continue to live with me in the months and years after reading them. These are some of my most beloved books, all of which happen to be under 200 pages, which ache with the inner mystery of what is hidden, and what is revealed. These books are my teachers, each a precise masterclass in world building, suspense, and purposeful storytelling. Enjoy these ‘swift shocks!’

Chana Porter Why did Chana love this book?

The first in a series of surreal, poetic short novels, set in the fictional city of Ravicka, a linguist-travelerarrives during an unspecified state of emergency. Event Factory feels like a travelog of an unsettling yet beautiful dream. I return to this book often and always get something differentthe events evaporate, but the details remain. You can easily enjoy Event Factory as a standalone novel. Gladman is a master. Fun fact: Dorothy, the small feminist press which publishes these books, began specifically to launch these singular novels.

What is this book about?

“More Kafka than Kafka, Renee Gladman’s achievement ranks alongside many of Borges’ in its creation of a fantastical landscape with deep psychological impact.” —Jeff VanderMeer

A “linguist-traveler” arrives by plane to Ravicka, a city of yellow air in which an undefined crisis is causing the inhabitants to flee. Although fluent in the native language, she quickly finds herself on the outside of every experience. Things happen to her, events transpire, but it is as if the city itself, the performance of life there, eludes her. Setting out to uncover the source of the city’s erosion, she is beset by this…


Book cover of The Courage to be

Dr. CI Author Of DEI-ing: A Guide to Navigating the Gotdamn Mess They’ve Made of Diversity, Equity, and Inclusion

From my list on pushing you into badassery.

Why am I passionate about this?

I’ve been in the DEI trenches for over 20 years, and let me tell you, it's been one hell of a ride. As a Black woman navigating this shit show, I've seen it all—from clueless executives to well-meaning “allies” who can't get out of their own way. My passion? Calling out the bullshit and actually making DEI work. I've gone toe-to-toe with tech giants, founded Inclusology, and now I'm tackling a second PhD because I believe in the work, even at is most discouraging. DEI-ing is my no-holds-barred guide to creating real change. I’m all about busting AI bias and building DEI that sticks, not just some feel-good fluff.

I stumbled upon this one because Trump had it on his desk—go figure. Tillich, a Christian philosopher, explains how fear and anxiety drive people to irrationality. It’s wild because the very ideas he discusses were twisted for Trump’s campaign.

But Tillich’s insights on how fear pushes us to lose our mind—and how to stay courageous when the world seems to have lost its grip—are pure gold. This book is as relevant as ever.

By Paul Tillich,

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

What is this book about?

Paul Tillich describes the dilemma of modern man and points a way to the conquest of the problem of anxiety. This edition includes a new introduction reflecting on the impact of the book since it was written.


Book cover of To Have or to Be?

Steve Taylor Author Of Extraordinary Awakenings: When Trauma Leads to Transformation

From my list on spiritual psychology.

Why am I passionate about this?

I’m a spiritual psychologist who investigates areas such as spiritual experiences, personal transformation, near-death experiences, and psi. I also write spiritual poetry. I had spiritual experiences (feelings of euphoria, harmony, and connection to my surroundings) as a teenager and always wondered why they occurred, how common they were in others, and whether they could become permanent. I became involved in the field of transpersonal psychology (which really is spiritual psychology) largely because I wanted to answer those questions. I see myself as an explorer of “the farther reaches of human nature” (in Abraham Maslow’s phrase). I’ve written many books about my explorations, including The Leap, Spiritual Science, and my new book Extraordinary Awakenings

Steve's book list on spiritual psychology

Steve Taylor Why did Steve love this book?

Erich Fromm isn’t so well known nowadays, but I am a great admirer of his. He developed a wide-ranging vision of individual and collective well-being. He investigated the whole spectrum of human nature, from the cruelty and brutality of Nazi Germany (which he personally experienced, as a German Jew who escaped to the United States) to love and altruism. This book is his last major work, in which he decries modern society’s emphasis on having and suggests that the only authentic and fulfilling mode of life is being. He develops a concept of a new type of human being who lives in harmony with themselves and the world. Fromm rarely wrote explicitly about spirituality, but it’s an underlying theme of almost everything he wrote. 

By Erich Fromm,

Why should I read it?

1 author picked To Have or to Be? as one of their favorite books, and they share why you should read it.

What is this book about?

To Have Or to Be? is one of the seminal books of the second half of the 20th century. Nothing less than a manifesto for a new social and psychological revolution to save our threatened planet, this book is a summary of the penetrating thought of Eric Fromm. His thesis is that two modes of existence struggle for the spirit of humankind: the having mode, which concentrates on material possessions, power, and aggression, and is the basis of the universal evils of greed, envy, and violence; and the being mode, which is based on love, the pleasure of sharing, and…


Book cover of I and Thou

Barbara Newman Author Of The Permeable Self: Five Medieval Relationships

From my list on being a person in community.

Why am I passionate about this?

In my career as a medievalist, I’ve been inspired by L. P. Hartley’s maxim that “the past is a foreign country: they do things differently there.” At the same time, the people who live there are humans like ourselves. So, I’ve always tried to balance the alterity with the universality of the medieval past, asking big questions that bring together a wide range of sources and genres. In my forty years of teaching at Northwestern, I’ve enjoyed watching the impact of medieval texts change with each generation of students as they discover this strange yet immensely generative world. 

Barbara's book list on being a person in community

Barbara Newman Why did Barbara love this book?

I first read this book in college, and it has powerfully shaped my philosophy of life. Martin Buber, the great Jewish thinker, distinguished between “I-It” relationships, in which we use another person instrumentally, and “I-Thou” relationships, in which we encounter another face to face. He argues that personhood begins in the prenatal life of the child flowing to and from its mother, but ends in God where all parallel relations intersect.

As a lifelong cat lover, I’m especially fond of his idea that personhood is not limited by species. Buber recognized that we can authentically say “Thou” to a cat or even a tree. 

By Martin Buber,

Why should I read it?

3 authors picked I and Thou as one of their favorite books, and they share why you should read it.

What is this book about?

Buber's main proposition is that we may address existence in two ways: [1] that of the "I" towards an "It", towards an object that is separate in itself, which we either use or experience; [2] that of the 'I' towards 'Thou', in which we move into existence in a relationship without bounds. One of the major themes of the book is that human life finds its meaningfulness in relationships. All of our relationships, Buber contends, bring us ultimately into relationship with God, who is the Eternal Thou.


Considered a landmark of twentieth-century intellectual history, this is Martin Buber's classic treatment…


Book cover of The Odes of John Keats

Ruth Schwertfeger Author Of A Nazi Camp Near Danzig: Perspectives on Shame and on the Holocaust from Stutthof

From my list on authors shaped by education in medicine.

Why am I passionate about this?

I find that one of the advantages of having worked as a professor (now Emerita ) of German at the University of Wisconsin, Milwaukee, is that it helped me gain perspective. When I study literature–especially in languages other than English–I am forced to step outside of my everyday world to identify the motif and leitmotif of the author. I am proposing that the medical training of these five authors helped them do the same: to dig below the surface to find other structures and root causes and to present their findings and unique diagnoses.  

Ruth's book list on authors shaped by education in medicine

Ruth Schwertfeger Why did Ruth love this book?

Beauty transcends transience and remains a thing of beauty that is a joy forever. The words of the odes of John Keats are familiar, but we forget that the poet was originally apprenticed to a surgeon in 1811. He knew disease and death firsthand, and many of his odes were written while he himself was suffering.

His medical training and recognition of death informed his vivid imagery; his awareness of the brevity of life compelled him to capture beauty in the ephemeral and transcendence in the transient. I boldly propose that Keats’s poetry would resonate with this generation of young readers. They will lean into its musicality and find comfort in the cadence of his verse.   

By Helen Vendler,

Why should I read it?

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

What is this book about?

Helen Vendler widens her exploration of lyric poetry with a new assessment of the six great odes of John Keats and in the process gives us, implicitly, a reading of Keats's whole career. She proposes that these poems, usually read separately, are imperfectly seen unless seen together-that they form a sequence in which Keats pursued a strict and profound inquiry into questions of language, philosophy, and aesthetics.

Vendler describes a Keats far more intellectually intent on creating an aesthetic, and on investigating poetic means, than we have yet seen, a Keats inquiring into the proper objects of worship for man,…


Book cover of Imagery, Ritual, and Birth: Ontology between the Sacred and the Secular

Ann W. Duncan Author Of Sacred Pregnancy: Birth, Motherhood, and the Quest for Spiritual Community

From my list on exploring the spirituality of pregnancy and birth.

Why am I passionate about this?

I became a mother while a graduate student. Bombarded by societal expectations and advice on pregnancy, childbirth, and motherhood, I quickly combined this life experience with my scholarly interests and wrote a dissertation on Christian women and childbirth. I later began to explore expressions of religion and spirituality outside of traditional religion – a topic that found expression in my book Sacred Pregnancy. I am a professor of American Studies and Religion at Goucher College in Baltimore, MD and have a Ph.D. in Religious Studies from the University of Virginia. I hope you enjoy these books as much as I have!

Ann's book list on exploring the spirituality of pregnancy and birth

Ann W. Duncan Why did Ann love this book?

Hennessey’s book looks directly at how birthing people use specific objects, ritual, poetry, and other aspects of material culture to infuse experiences of birth with ritual and being.

She blends theory with specific and captivating examples to develop a social ontology of birth – in other words, a description of how meaning in birth is created through these objects. What emerges is a striking case for the potential of birth for ritual and meaning and the necessary interweaving of religion, nonreligion, and a sense of the sacred.

By Anna M. Hennessey,

Why should I read it?

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

What is this book about?

Every human being is born and has gone through a process of birth. Yet the topic of birth remains deeply underrepresented in the humanities, overshadowed by a scholarly focus on death. This book explores how imagery is used ritualistically in religious, secular, and nonreligious ways during birth, through analysis of a wide variety of art, iconography, poetry, and material culture. Objects central to the book's study include religious figurines, paintings about birth, and other items representative of pregnancy, crowning, or giving birth that have an historical or original meaning connected to religion. Contemporary artists are also creating new art in…


Book cover of Being and Time

Lee Braver Author Of Heidegger: Thinking of Being

From my list on everything you want to know on existentialism.

Why am I passionate about this?

I’m a professor of philosophy because when I got to college, philosophy sounded like what Gandalf would study—the closest thing we have to the study of magic. It turns out, I wasn’t far from the mark. Philosophy shows you entire dimensions to the world that you never noticed because they exist at weird angles, and you have to change your way of thinking to see them. Entering them and seeing the world from those perspectives transforms everything. A great work of philosophy is like having the lights turn on in an annex of your mind you didn’t know was there, like an out-of-mind experience—or perhaps, an in-your-mind-for-the-first-time experience.

Lee's book list on everything you want to know on existentialism

Lee Braver Why did Lee love this book?

If aliens land and ask me what it’s like to be a human, I’ll give them Heidegger’s first book, Being and Time. Of course, that might prompt them to destroy all humans out of frustration at the difficulty of his writing, but if they persevere, they will find the best description of what it’s like to live out your time on this planet (One Hundred Years of Solitude comes in second).

By Martin Heidegger, John MacQuarrie (translator), Edward S. Robinson (translator)

Why should I read it?

3 authors picked Being and Time as one of their favorite books, and they share why you should read it.

What is this book about?

A knowledge of Heidegger's Sein und Zeit is essential for anyone who wishes to understand a great deal of recent continental work in theology as well as philosophy. Yet until this translation first appeared in 1962, this fundamental work of one of the most influential European thinkers of the century remained inaccessible to English readers. In fact the difficulty of Heidegger's thought was considered to be almost insuperable in the medium of a foreign language, especially English. That this view was unduly pessimistic is proved by the impressive work of John Macquarrie and Edward Robinson who have succeeded in clothing…
