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.

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.

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.

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.

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 a blossoming garden located far outside all worlds, a group of aging Greek gods have gathered to discuss the nature of existence, the mystery of mind, and whether there is a transcendent God from whom all things come. Turning to Eros, Psyche asks, "Do you see this flower, my love?"

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?

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.

This audiobook narrated by acclaimed archaeologist and best-selling author Eric Cline offers a breathtaking account of how the collapse of an ancient civilized world ushered in the first Dark Ages.

Virtual reality is genuine reality; that’s the central thesis of Reality+. In a highly original work of “technophilosophy,” David J. Chalmers gives a compelling analysis of our technological future. He argues that virtual worlds are not second-class worlds, and that we can live a meaningful life in virtual reality. We may even be in a virtual world already.

As it absorbs data, gains agency, and intermediates between humans and reality, AI will help us to address enormous crises, from climate change to geopolitical conflicts to income inequality. It might well solve some of the greatest mysteries of our universe, revolutionize fields as diverse as medicine and architecture, and elevate the human spirit to unimaginable heights. But it will also pose challenges on a scale and of an intensity that we have never seen.

Humans have long thought of their bodies and minds as separate spheres of existence. The body is physical. 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.

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.

What is our place in the universe? Are we alone? - and provide answers based on the most current data, observations, and theories.

At the end of his career, Albert Einstein was pursuing a dream far more ambitious than the theory of relativity. He was trying to find an equation that explained all physical reality - a theory of everything. Experimental physicist and award-winning educator Dr. Don Lincoln takes you on this exciting journey in The Theory of Everything: The Quest to Explain All Reality. Suitable for the intellectually curious at all levels and assuming no background beyond basic high-school math, these 24 half-hour lectures cover recent developments at the forefront of particle physics and cosmology.

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.

"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.

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.

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.

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.

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.

Part of Ivan Doig’s acclaimed Montana trilogy, English Creek revolves around Jick McCaskill, a 14-year-old growing up in 1930s Montana. This incandescent coming-of-age tale dramatizes the climatic events of one summer that inevitably mark Jick’s awakening from childhood to adulthood.

Thomas Piketty's work has proved that unfettered markets lead to increasing inequality. Without meaningful regulation, capitalist economies will concentrate wealth in an ever smaller number of hands. Armed with this knowledge, democratic societies face a defining challenge: fending off a new aristocracy. For years Piketty has wrestled with this problem in his monthly newspaper column, which pierces the surface of current events to reveal the economic forces underneath.

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.
