In very recent times humanity has learnt a vast amount about the universe, the past, and itself. But through our remarkable successes in acquiring knowledge we have learned how much we have yet to learn: the science we have, for example, addresses just 5% of the universe; pre-history is still being revealed, with thousands of historical sites yet to be explored; and the new neurosciences of mind and brain are just beginning.
What do we know, and how do we know it? What do we now know that we don't know? And what have we learnt about the obstacles to knowing more? In a time of deepening battles over what knowledge and truth mean, these questions matter more than ever.
Bestselling polymath and philosopher A. C. Grayling seeks to answer them in three crucial areas at the frontiers of knowledge: science, history, and psychology. In each area he illustrates how each field has advanced to where it is now, from the rise of technology to quantum theory, from the dawn of humanity to debates around national histories, from ancient ideas of the brain to modern theories of the mind.
A remarkable history of science, life on earth, and the human mind itself, this is a compelling and fascinating tour de force, written with Grayling's verve, clarity and remarkable breadth of knowledge.

If you thought you knew who you were, THINK AGAIN. Did you know that half your DNA isn't human? That somebody, somewhere has exactly the same face? Or that most of your memories are fiction? What about the fact that you are as hairy as a chimpanzee, various parts of your body don't belong to you, or that you can read other people's minds? Do you really know why you blush, yawn and cry? Why 90 per cent of laughter has nothing to do with humour? Or what will happen to your mind after you die? You belong to a unique, fascinating and often misunderstood species. How to be Human is your guide to making the most of it.

What does drug withdrawal have in common with a broken heart? Why is the enemy of memory not time, but other memories? How can a blind person learn to see with her tongue or a deaf person learn to hear with his skin? Why did many people in the 1980s mistakenly perceive book pages to be slightly red in colour? Why is the world's best archer armless? Might we someday control a robot with our thoughts, just as we do our fingers and toes? Why do we dream at night, and what does that have to do with the rotation of the planet? The answer to these questions is right behind our eyes. The greatest technology we have ever discovered on this planet is the three-pound organ carried around in the vault of the skull. This book is not simply about what the brain is, but what it does. The magic of the brain is not found in the parts it's made of, but in the way those parts unceasingly re-weave themselves in an electric, living fabric. Surf the leading edge of neuroscience atop the anecdotes and metaphors that have made Eagleman one of the best scientific translators of our generation. Covering decades of research to the present day, Livewired also presents new discoveries from Eagleman's own laboratory, from synaesthesia to dreaming to wearable neurotech devices that revolutionize how we think about the senses.

Science world luminary John Brockman assembles twenty-five of the most important scientific minds, people who have been thinking about the field artificial intelligence for most of their careers, for an unparalleled round-table examination about mind, thinking, intelligence and what it means to be human. 'Artificial intelligence is today's story--the story behind all other stories. It is the Second Coming and the Apocalypse at the same time: Good AI versus evil AI.' --John Brockman More than sixty years ago, mathematician-philosopher Norbert Wiener published a book on the place of machines in society that ended with a warning: 'we shall never receive the right answers to our questions unless we ask the right questions.... The hour is very late, and the choice of good and evil knocks at our door.' In the wake of advances in unsupervised, self-improving machine learning, a small but influential community of thinkers is considering Wiener's words again. In Possible Minds, John Brockman gathers their disparate visions of where AI might be taking us. The fruit of the long history of Brockman's profound engagement with the most important scientific minds who have been thinking about AI--from Alison Gopnik and David Deutsch to Frank Wilczek and Stephen Wolfram--Possible Minds is an ideal introduction to the landscape of crucial issues AI presents. The collision between opposing perspectives is salutary and exhilarating; some of these figures, such as computer scientist Stuart Russell, Skype co-founder Jaan Tallinn, and physicist Max Tegmark, are deeply concerned with the threat of AI, including the existential one, while others, notably robotics entrepreneur Rodney Brooks, philosopher Daniel Dennett, and bestselling author Steven Pinker, have a very different view. Serious, searching and authoritative, Possible Minds lays out the intellectual landscape of one of the most important topics of our time.

From the world-renowned physicist and bestselling author of The Elegant Universe and The Fabric of the Cosmos, a captivating exploration of deep time and humanity's search for purpose In both time and space, the cosmos is astoundingly vast, and yet is governed by simple, elegant, universal mathematical laws. On this cosmic timeline, our human era is spectacular but fleeting. Someday, we know, we will all die. And, we know, so too will the universe itself. Until the End of Time is Brian Greene's breathtaking new exploration of the cosmos and our quest to understand it. Greene takes us on a journey across time, from our most refined understanding of the universe's beginning, to the closest science can take us to the very end. He explores how life and mind emerged from the initial chaos, and how our minds, in coming to understand their own impermanence, seek in different ways to give meaning to experience: in story, myth, religion, creative expression, science, the quest for truth, and our longing for the timeless, or eternal. Through a series of nested stories that explain distinct but interwoven layers of reality-from the quantum mechanics to consciousness to black holes-Greene provides us with a clearer sense of how we came to be, a finer picture of where we are now, and a firmer understanding of where we are headed. Yet all this understanding, which arose with the emergence of life, will dissolve with its conclusion. Which leaves us with one realization: during our brief moment in the sun, we are tasked with the charge of finding our own meaning. Let us embark.

A lively and highly readable account of the origins, invention and discovery of just about everything on the planet, the truly global coverage of The First of Everything ranges from the Big Bang to driverless cars. The First of Everything follows a context-setting introduction with seven stimulating sections: In the Beginning (The Big Bang to Homo Sapiens), At Home (the first glass windows to dentures and bikinis); Health and Medicine (herbs to heart transplants); Getting About (donkeys to double deckers); Science and Engineering (potter's wheel to webcam); Peace and War (the first king to fighter-bombers); and Culture (cave painting to rap). This fascinating book takes in the full sweep of human development and ingenuity over twelve millennia; Africa, for example, gave us the first monarch, algebra and great religions emerged from the Middle East, democracy was born in Europe, and America made the first flying machines. More than just a string of dry lists, the colourful text's intriguing insights and asides make it as enjoyable for the casual browser as the more serious researcher.

At the end of a steep gravel road in one of the remotest corners of South Africa's Eastern Cape lies the village of Ithanga. Home to a few hundred villagers, the majority of them unemployed, it is inconceivably poor. It is to here that award-winning author Jonny Steinberg travels to explore the lives of a community caught up in a battle to survive the ravages of the greatest plague of our times, the African AIDS epidemic.

He befriends Sizwe, a young local man who refuses to be tested for AIDS despite the existence of a well-run testing and anti-retroviral programme. It is Sizwe's deep ambivalence, rooted in his deep sense of the cultural divide, that becomes the key to understanding the dynamics that thread their way through a terrified community.

As Steinberg grapples to get closer to finding answers that remain just out of reach, he realizes that he must look within himself to unlock the paradoxes at the heart of his country.
