What is life? This is among the most difficult open problems in science, right up there with the nature of consciousness and the existence of matter. All the definitions we have fall short. None help us understand how life originates or the full range of possibilities for what life on other planets might look like. In Life as No One Knows It, physicist and astrobiologist Sara Imari Walker argues that solving the origin of life requires radical new thinking and an experimentally testable theory for what life is.

Why are we here? What's the point of existence? On the "big questions" of meaning and purpose, Western thought has been dominated by the dichotomy of traditional religion and secular atheism. In this pioneering work, Philip Goff argues that it is time to move on from both God and atheism. Through an exploration of contemporary cosmology and cutting-edge philosophical research on consciousness, Goff argues for cosmic purpose: the idea that the universe is directed towards certain goals, such as the emergence of life.

What links conscious experience of pain, joy, color, and smell to bio-electrical activity in the brain? Christof Koch has devoted much of his career to bridging the seemingly unbridgeable gap between the physics of the brain and phenomenal experience. This engaging book - part scientific overview, part memoir, part futurist speculation - describes Koch's search for an empirical explanation for consciousness.

How do neurons turn into minds? The problem of consciousness has gnawed at us for millennia. In the last century there have been massive breakthroughs that have rewritten the science of the brain, and yet the puzzles faced by the ancient Greeks are still present. In The Consciousness Instinct, the neuroscience pioneer Michael S. Gazzaniga puts the latest research in conversation with the history of human thinking about the mind, giving a big-picture view of what science has revealed about consciousness.

Here are three important but very different Dialogues from the Middle Period. Symposium, the most well-known in this collection, is concerned with the theme of love. In the house of Agathon, a group of friends - each very different in personality and background - meet to consider and discuss various kinds of love. Each one, Phaedrus, Pausanias, Eryximachus, Aristophanes (the playwright) and Agathon (a prize-winning tragic poet), presents his particular view in a short discourse.

How does a neural network become a brain? While neurobiologists investigate how nature accomplishes this feat, computer scientists interested in AI strive to achieve this through technology. The Self-Assembling Brain tells the stories of both fields, exploring the historical and modern approaches taken by the scientists pursuing answers to the quandary: What information is necessary to make an intelligent neural network? As Peter Robin Hiesinger argues, "the information problem" underlies both fields.

Dip below the ocean’s surface and you are soon confronted by forms of life that could not seem more foreign to our own: sea sponges, soft corals, and serpulid worms, whose rooted bodies, intricate geometry, and flower-like appendages are more reminiscent of plant life or even architecture than anything recognizably animal. Yet these creatures are our cousins. As fellow members of the animal kingdom — the Metazoa— they can teach us much about the evolutionary origins of not only our bodies, but also our minds.

In a universe filled by chaos and disorder, one physicist makes the radical argument that the growth of order drives the passage of time - and shapes the destiny of the universe.

For as long as we’ve studied human cognition, we’ve believed that our senses give us direct access to the world. What we see is what’s really there—or so the thinking goes. But new discoveries in neuroscience and psychology have turned this assumption on its head. What if rather than perceiving reality passively, your mind actively predicts it?

We feel, therefore we are. Conscious sensations ground our sense of self. They are crucial to our idea of ourselves as psychic beings: present, existent, and mattering. But is it only humans who feel this way? Do other animals? Will future machines? Weaving together intellectual adventure and cutting-edge science, Nicholas Humphrey describes in Sentience his quest for answers: from his discovery of blindsight in monkeys and his pioneering work on social intelligence to breakthroughs in the philosophy of mind.

In Waves in an Impossible Sea, physicist Matt Strassler tells a startling tale of elementary particles, human experience, and empty space. He begins with a simple mystery of motion. When we drive at highway speeds with the windows down, the wind beats against our faces. Yet our planet hurtles through the cosmos at 150 miles per second, and we feel nothing of it. How can our voyage be so tranquil when, as Einstein discovered, matter warps space, and space deflects matter? The answer, Strassler reveals, is that empty space is a sea, albeit a paradoxically strange one.

We humans are the inheritors of a dynasty that has reigned over the planet for nearly 66 million years, through fiery cataclysm and ice ages: the mammals. Our lineage includes saber-toothed tigers, woolly mammoths, armadillos the size of a car, cave bears three times the weight of a grizzly, clever scurriers that outlasted Tyrannosaurus rex, and even other types of humans, like Neanderthals.

Challenging leading scientific theories that claim that our senses report back objective reality, cognitive scientist Donald Hoffman argues that while we should take our perceptions seriously, we should not take them literally. How can it be possible that the world we see is not objective reality? And how can our senses be useful if they are not communicating the truth? Hoffman grapples with these questions and more over the course of this eye-opening work.

Scientists are learning more and more about how brain activity controls behavior and how neural circuits weigh alternatives and initiate actions. As we probe ever deeper into the mechanics of decision making, many conclude that agency—or free will—is an illusion. In Free Agents, leading neuroscientist Kevin Mitchell presents a wealth of evidence to the contrary, arguing that we are not mere machines responding to physical forces but agents acting with purpose.

Technofeudalism says Yanis Varoufakis, is the new power that is reshaping our lives and the world, and is the greatest current threat to the liberal individual, to our efforts to avert climate catastrophe—and to democracy itself. It also lies behind the new geopolitical tensions, especially the New Cold War between the United States and China. Drawing on stories from Greek myth and pop culture, from Homer to Mad Men, Varoufakis explains this revolutionary transformation: how it enslaves our minds, how it rewrites the rules of global power, and, ultimately, what it will take overthrow it.

My Big TOE: Awakening, written by a nuclear physicist in the language of contemporary culture, unifies science and philosophy, physics and metaphysics, mind and matter, purpose and meaning, the normal and the paranormal. The entirety of human experience (mind, body, and spirit) including both our objective and subjective worlds is brought together under one seamless scientific understanding.

We are in the midst of a global mental health crisis, and mental illnesses are on the rise. But what causes mental illness? And why are mental health problems so hard to treat? Drawing on decades of research, Harvard psychiatrist Dr. Chris Palmer outlines a revolutionary new understanding that for the first time unites our existing knowledge about mental illness within a single framework: mental disorders are metabolic disorders of the brain. Brain Energy will transform the field of mental health, and the lives of countless people around the world.

Remarkable new discoveries affirm the octopus as one of nature’s most intelligent and complex animals. This new book brings us closer than ever to these elusive creatures. The companion to the highly anticipated National Geographic television special, this book explores the alluring underwater world of the octopus—a creature that resembles an alien lifeform, but whose behavior has earned it a reputation as one of the most intelligent animals on the planet.

Hilarious, fascinating, and a roller coaster of dizzying, historical what-ifs, Napoleon's Hemorrhoids is a potpourri for serious historians and casual history buffs. In one of Phil Mason's many revelations, you'll learn that Communist jets were two minutes away from opening fire on American planes during the Cuban missile crisis, when they had to turn back as they were running out of fuel. You'll discover that before the Battle of Waterloo, Napoleon's painful hemorrhoids prevented him from mounting his horse to survey the battlefield.

Richard Dawkins' brilliant reformulation of the theory of natural selection has the rare distinction of having provoked as much excitement and interest outside the scientific community as within it. His theories have helped change the whole nature of the study of social biology, and have forced thousands to rethink their beliefs about life.

Psychologists study which cognitive operations underpin a given conscious perception. Neuroscientists track the neural correlates of consciousness in the brain, the organ of the mind. But why the brain and not, say, the liver? How can the brain, three pounds of highly excitable matter, a piece of furniture in the universe, subject to the same laws of physics as any other piece, give rise to subjective experience? Koch argues that what is needed to answer these questions is a quantitative theory that starts with experience and proceeds to the brain.

What links conscious experience of pain, joy, color, and smell to bio-electrical activity in the brain? Christof Koch has devoted much of his career to bridging the seemingly unbridgeable gap between the physics of the brain and phenomenal experience. This engaging book - part scientific overview, part memoir, part futurist speculation - describes Koch's search for an empirical explanation for consciousness.

Have you ever wondered why you exist? What had to happen for you to be alive and conscious? Scientists have come a long way in answering this question, and this book describes what they have found out. It also examines whether our existence was inevitable at the universe's birth 13.77 billion years ago—or whether we are just incredibly lucky. The book is aimed at those who are interested in science but are not experts.

From Plato to Westworld, these questions have fascinated and befuddled philosophers, artists, and scientists for centuries. In The Forgetting Machine, neuroscientist Rodrigo Quian Quiroga explains how the mechanics of memory illuminates these discussions, with implications for everything from understanding Alzheimer's disease to the technology of Artificial Intelligence.

Is consciousness a fundamental building block of the universe, like gravity? Can humans develop new senses through neuroscience? And can artificial intelligence ever truly replicate the subjective experience of being conscious? Join Annaka Harris as she calls on distinguished experts in science and philosophy to find answers to today’s most perplexing questions about our minds and the universe at large.

This text revolves around a new and unusual view on the most fundamental puzzle of physics. It focuses on the key aspect that makes the role of the time dimension fundamentally different: causality. The implicit and intuitive way by which causality is usually taken for granted is just made explicit and less self-evident, shedding a new light on the gravity-quantum conflict. The case is made that gravity is a necessary condition for a causal universe.

The Cell: Inside the Microscopic World that Determines Our Health, Our Consciousness, and Our Future is a fascinating story of the incredible complexity and dynamism inside the cell and of the fantastic advancements in our understanding of this microscopic world.

One of the most powerful acts of devotion is also one of the most simple: bowing down and surrendering to the earth. This is the basis for "The Five Prostrations", a time-honored Buddhist meditation practice that joins the mind and body. On Touching the Earth, Buddhist masters Thich Nhat Hanh and Sister Chan Khong update this ancient teaching for the modern student. You learn each phase of this practice, which will help empty your body of resentment while opening it to compassion for all life.

From ventilators to brain implants, medicine has been blurring what it means to die. In a lucid description of modern neuroscientific thinking, Zeleznikow-Johnston explains that death is not the loss of breath, but of personal identity – that the core of our identities is our minds, and that our minds are encoded in the structure of our brains. On this basis, he explores how recent discoveries now offer us all the chance of preserving our minds for future revival. Whether they discovered cures or fought for justice, we are grateful to those of our ancestors who helped craft a kinder world.

In Charged, James Morton Turner unpacks the history of batteries to explore why solving "the battery problem" is critical to a clean energy transition. As climate activists focus on what a clean energy future will create the history of batteries offers a sharp reminder of what building that future will consume. With new insight on the consequences for people and communities on the front lines, Turner draws on the past for crucial lessons that will help us build a just and clean energy future, from the ground up.

Astrophysicist J. Craig Wheeler, former president of the American Astronomical Society, takes a critical look at the technological advances shaping our future. From artificial intelligence to genetic engineering, Wheeler explores how these innovations are interconnected and the potential they hold for humanity's evolution. With thought-provoking insights into the ethical dilemmas we face, Wheeler stresses the importance of staying informed and proactive.

Before being struck down by the US Supreme Court in June 2023, affirmative action remained one of the few remaining policy tools to address racial inequalities, revealing peculiar contours of racism and anti-racist strategies in America. Through personal reflective essays for and about her daughter, OiYan Poon looks at how the debate over affirmative action reveals the divergent ways Asian Americans conceive of their identity.

"Consciousness is what makes the mind-body problem really intractable." So begins Thomas Nagel's classic 1974 essay "What is it Like to be a Bat?" Nagel's essay initiated the now widespread attention to consciousness as a central problem for philosophy, psychology, and neuroscience; it also influenced the recognition of the consciousness of nonhuman creatures as an important subject of study.

What does it mean to “be you” - that is, to have a specific, conscious experience of the world around you and yourself within it? There may be no more elusive or fascinating question. Historically, humanity has considered the nature of consciousness to be a primarily spiritual or philosophical inquiry, but scientific research is now mapping out compelling biological theories and explanations for consciousness and selfhood.
