The Four Realms of Existence


Book Description

Joseph LeDoux argues that ideas like the self are increasingly barriers to discovery and understanding. He offers a new framework, theorizing four realms of existence--bodily, neural, cognitive, and conscious. Together, these four realms operate continuously as an "ensemble of being" to make humans who and what we are.




The Four Realms of Existence


Book Description

One of the world’s leading experts on mind and brain takes us on an expedition that reveals a new view of what makes us who we are. Humans have long thought of their bodies and minds as separate spheres of existence. The body is physical—the source of aches and pains. But the mind is mental; it perceives, remembers, believes, feels, and imagines. Although modern science has largely eliminated this mind-body dualism, people still tend to imagine their minds as separate from their physical being. Even in research, the notion of the “self” as somehow distinct from the rest of the organism persists. Joseph LeDoux argues that we have hit an epistemological wall—that ideas like the self are increasingly barriers to discovery and understanding. He offers a new framework of who we are, theorizing four realms of existence—bodily, neural, cognitive, and conscious. The biological realm makes life possible. Hence, every living thing exists biologically. Animals, uniquely, supplement biological existence with a nervous system. This neural component enables them to control their bodies with speed and precision unseen in other forms of life. Some animals with nervous systems possess a cognitive realm, which allows the creation of internal representations of the world around them. These mental models are used to control a wide range of behaviors. Finally, the conscious realm allows its possessors to have inner experiences of, and thoughts about, the world. Together, LeDoux shows, these four realms make humans who and what we are. They cooperate continuously and underlie our capacity to live and experience ourselves as beings with a past, present, and future. The result, LeDoux shows, is not a self but an “ensemble of being” that subsumes our entire human existence, both as individuals and as a species.




The Deep History of Ourselves


Book Description

Longlisted for the PEN/E.O. Wilson Literary Science Writing Award A leading neuroscientist offers a history of the evolution of the brain from unicellular organisms to the complexity of animals and human beings today Renowned neuroscientist Joseph LeDoux digs into the natural history of life on earth to provide a new perspective on the similarities between us and our ancestors in deep time. This page-turning survey of the whole of terrestrial evolution sheds new light on how nervous systems evolved in animals, how the brain developed, and what it means to be human. In The Deep History of Ourselves, LeDoux argues that the key to understanding human behavior lies in viewing evolution through the prism of the first living organisms. By tracking the chain of the evolutionary timeline he shows how even the earliest single-cell organisms had to solve the same problems we and our cells have to solve each day. Along the way, LeDoux explores our place in nature, how the evolution of nervous systems enhanced the ability of organisms to survive and thrive, and how the emergence of what we humans understand as consciousness made our greatest and most horrendous achievements as a species possible.




The Laws of the Spirit World


Book Description

WITH A BRAND NEW LOOK! ON FEBRUARY 22, 1980, KHORSHED AND RUMI BHAVNAGRI’S WORLD WAS SHATTERED. ONE MONTH LATER, A NEW ONE OPENED. Khorshed and Rumi Bhavnagri lost their sons, Vispi and Ratoo, in a tragic car crash. With both their sons gone, the couple felt they would not survive for long. They had lost all faith in God until a miraculous message from the Spirit World gave them hope and sent them on an incredible journey.




Governing Behavior


Book Description

From simple reflexes to complex movements, all animal behavior is governed by a nervous system. But what kind of government is it—a dictatorship or a democracy? Ari Berkowitz explains the variety of structures and strategies that control behavior, while providing an overview of thought-provoking debates and cutting-edge research.




Anxious


Book Description

“A rigorous, in-depth guide to the history, philosophy, and scientific exploration of this widespread emotional state . . . [LeDoux] offers a magisterial review of the role of mind and brain in the generation of unconscious defense responses and consciously expressed anxiety. . . . [His] charming personal asides give an impression of having a conversation with a world expert.” —Nature A comprehensive and accessible exploration of anxiety, from a leading neuroscientist and the author of Synaptic Self Collectively, anxiety disorders are our most prevalent psychiatric problem, affecting about forty million adults in the United States. In Anxious, Joseph LeDoux, whose NYU lab has been at the forefront of research efforts to understand and treat fear and anxiety, explains the range of these disorders, their origins, and discoveries that can restore sufferers to normalcy. LeDoux’s groundbreaking premise is that we’ve been thinking about fear and anxiety in the wrong way. These are not innate states waiting to be unleashed from the brain, but experiences that we assemble cognitively. Treatment of these problems must address both their conscious manifestations and underlying non-conscious processes. While knowledge about how the brain works will help us discover new drugs, LeDoux argues that the greatest breakthroughs may come from using brain research to help reshape psychotherapy. A major work on one of our most pressing mental health issues, Anxious explains the science behind fear and anxiety disorders. Praise for Anxious: “[Anxious] helps to explain and prevent the kinds of debilitating anxieties all of us face in this increasingly stressful world.” —Daniel J. Levitin, author of The Organized Mind and This Is Your Brain on Music “A careful tour through the current neuroscience of fear and anxiety . . . [Anxious] will reward the informed reader.” —The Wall Street Journal “An extraordinarily ambitious, provocative, challenging, and important book. Drawing on the latest research in neuroscience (including work in his own laboratory), LeDoux provides explanations of the origins, nature, and impact of fear and anxiety disorders.” —Psychology Today




The City of Dusk


Book Description

This dark epic fantasy follows the heirs of four noble houses—each gifted with a divine power—as they form a tenuous alliance to keep their kingdom from descending into a realm-shattering war. The Four Realms—Life, Death, Light, and Darkness—all converge on the city of dusk. For each realm there is a god, and for each god there is an heir. But the gods have withdrawn their favor from the once vibrant and thriving city. And without it, all the realms are dying. Unwilling to stand by and watch the destruction, the four heirs—Risha, a necromancer struggling to keep the peace; Angelica, an elementalist with her eyes set on the throne; Taesia, a shadow-wielding rogue with rebellion in her heart; and Nik, a soldier who struggles to see the light—will sacrifice everything to save the city. But their defiance will cost them dearly.




Many Paths, Many Truths


Book Description

Have you ever wondered why there is so much religious diversity in the world? How did this story of humanity begin and what ancient wisdom has been lost along the way? Can you believe in God and not be religious? Or simply put, why do human beings have a need to believe in something… anything? This book is a journey through the genesis of faith, the evolution of ancient spiritual practices, the dawn of major world religions and an exploration of the emerging frontiers of New Age spirituality.




Rewired


Book Description

Living in an age of digital distraction has wreaked havoc on our brains—but there’s much we can do to restore our tech–life balance. We live in a world that is always on, where everyone is always connected. But we feel increasingly disconnected. Why? The answer lies in our brains. Carl D. Marci, MD, a leading expert on social and consumer neuroscience, reviews the mounting evidence that overuse of smart phones and social media is rewiring our brains, resulting in a losing deal: we are neglecting the relationships that sustain us and keep us healthy in favor of weaker and more ephemeral ties. The ability to connect and form strong social bonds is fundamental to human experience and emerged through unique structures in our brains. But ever-more-powerful technologies and ubiquitous access to media have hijacked our need to connect intimately and emotionally with others. The quick highs of clicking “like” and swiping right overstimulate the same neurological reward centers associated with social relationships. The habits that accompany our digital lifestyles are putting tremendous pressure on critical components of the brain associated with attention, emotion, and memory, changing how we process information and altering how we communicate and relate, even at a physiological level. As a psychiatrist working at the forefront of research on the impact of digital technology, Marci has seen this transformation up close and developed a range of responses. Rewired provides scientifically supported solutions for everyone who wants to restore their tech–life balance—from parents concerned about their children’s exposure to the internet to stressed workers dealing with the deluge of emails and managing the expectation of 24/7 availability.




The Emotional Brain


Book Description

What happens in our brains to make us feel fear, love, hate, anger, joy? Do we control our emotions, or do they control us? Do animals have emotions? How can traumatic experiences in early childhood influence adult behavior, even though we have no conscious memory of them? In The Emotional Brain, Joseph LeDoux investigates the origins of human emotions and explains that many exist as part of complex neural systems that evolved to enable us to survive. One of the principal researchers profiled in Daniel Goleman's Emotional Intelligence, LeDoux is a leading authority in the field of neural science. In this provocative book, he explores the brain mechanisms underlying our emotions -- mechanisms that are only now being revealed.
