Wat Moet Ons Met Ons Kerk Doen? is 'n poging om te probeer verstaan waar ons as Afrikaners teologies vandaan kom, watter kragte en magte ons en ons Kerk gevorm het en hoe ons Kerk tans daar uitsien.

Die N.G.Kerk was 'n belangrike en rigtinggewende rolspele in die opheffing van die Afrikaner na die Britse vergrype tydens en na die Tweede Vryheidsoorlog. Tans word die N.G.Kerk ervaar as 'n instansie wat ongevoelig teenoor die geestelike behoeftes van haar lidmate staan.

Hierdie is 'n moet-lees boek vir:

• Lidmate wat ons Kerk graag wil help om 'n gesonde, geestelike tuiste vir Suid-Afrikaners van die 21ste eeu te bied.
• Die klakkelose napraters van die dogma wat dink ons Kerk is steeds op die regte pad.
• Die plastiekpredikante van die radio en televisie wat met eentonige reëlmaat soetsappige, sogenaamd godsdienstige, pleisters plak.
• Diegene wat reeds ons Kerk tot die ashoop van die geloof verdoem het.

Everything you need to know about race (but were afraid to ask), previously published in 2015 as Black Brain, White Brain: Is Intelligence Skin Deep?.

In academic journals and on internet message boards, certain scientists and thinkers are laying siege to one of the great taboos. Could it be, they ask, that racism has a rational basis in science? These ideas are no longer limited to the fringe: race-based studies of intelligence have been discussed by thinkers such as Steven Pinker, Sam Harris and Jordan Peterson. If true, it would provide an intellectual foundation for so many of the attitudes that characterise the right wing, justifying inequality and discrimination. Gavin Evans tackles the nature vs nurture debate head-on, examining the latest studies on how intelligence develops and laying out new discoveries in genetics, palaeontology, archaeology and anthropology to unearth the truth about our shared past.

In doing so, Skin Deep demolishes the pernicious myth that our race is our destiny, and instead reveals what really makes us who we are.

WHEN we eat may be as important as WHAT we eat.

Like most people, you probably wake up, get hungry for meals and doze off in bed around the same time every day. If you’ve ever experienced jet lag or pulled an all-nighter, you know that this schedule can easily be thrown off kilter. But for some people, that imbalance—difficulty sleeping at night, hunger at odd times, or sudden fatigue at noon—is a constant. If you're one of those people, Dr. Satchin Panda, one of the leading researchers on circadian rhythms, has a plan to reset your body clock.

Beginning with an in-depth explanation of the circadian clock—why it’s important, how it works, and how to know it isn’t working—The Circadian Code outlines lifestyle changes to make to get back on track. It's a concrete plan to enhance weight loss, improve sleep, optimize exercise, and manage technology so that it doesn’t interfere with your body’s natural rhythm. Dr. Panda’s life changing methods show you how to prevent and reverse ailments like diabetes, cancer, and dementia, as well as microbiome conditions like acid reflux, heartburn, and irritable bowel disease.

An enchanting biography of the most resonant - and most necessary - chemical element on Earth. Carbon. It's in the fibres in your hair, the timbers in your walls, the food that you eat and the air that you breathe. It's worth billions as a luxury and half a trillion as a necessity, but there are still mysteries yet to be solved about the element that can be both diamond and coal. Where does it come from, what does it do, and why, above all, does life need it? With sparkling prose and engaging narrative, earth scientist Robert Hazen leads us on a vibrant journey through the origin and evolution of life's most ubiquitous element. The story unfolds in four movements - Earth, Air, Fire and Water - and transports us through 14 billion years of cosmic history. From the outer reaches of the universe to the cliffs of Scotland and into the precious-metal mines of Namibia, Symphony in C is a sweeping chronicle of carbon: the most essential element on Earth.

Longlisted for the National Book Award for Nonfiction and A New York Times Notable Book of 2018. Our understanding of the `tree of life', with powerful implications for human genetics, human health and our own human nature, has recently completely changed. This book is about a new method of telling the story of life on earth - through molecular phylogenetics. It involves a fairly simple method - the reading of the deep history of life by looking at the variation in protein molecules found in living organisms. For instance, we now know that roughly eight per cent of the human genome arrived not through traditional inheritance from directly ancestral forms, but sideways by viral infection. In The Tangled Tree, acclaimed science writer David Quammen chronicles these discoveries through the lives of the researchers who made them - such as Carl Woese, the most important little-known biologist of the twentieth century; Lynn Margulis, the notorious maverick whose wild ideas about `mosaic' creatures proved to be true; and Tsutomu Wantanabe, who discovered that the scourge of antibiotic-resistant bacteria is a direct result of horizontal gene transfer, bringing the deep study of genome histories to bear on a global crisis in public health. Quammen explains how molecular studies of evolution have brought startling recognitions about the tangled tree of life - including where we humans fit into it. Thanks to new technologies, we now have the ability to alter even our genetic composition - through sideways insertions, as nature has long been doing. The Tangled Tree is a brilliant exploration of our transformed understanding of evolution and of life's history itself.

A cutting-edge examination of what it means to be human and to have a 'self' in the face of new scientific developments in genetic editing, cloning and neural downloading. After seeing his own cells used to grow clumps of new neurons - essentially mini-brains - Philip Ball begins to examine the concepts of identity and consciousness. Delving into humanity's deep evolutionary past to look at how complex creatures like us emerged from single-celled life, he offers a new perspective on how humans think about ourselves. In an age when we are increasingly encouraged to regard the 'self' as an abstract sequence of genetic information, or as a pattern of neural activity that might be 'downloaded' to a computer, he return us to the body - to flesh and blood - and anchors a conception of personhood in this unique and ephemeral mortal coil. How to Build a Human brings us back to ourselves - but in doing so, it challenges old preconceptions and values. It asks us to rethink how we exist in the world.

This updated edition provides a fitting tribute to an enduring wildlife classic, destined to enthral the generation who saw it when first published and bring it alive for a whole new generation.

Bone is a marvel, an adaptable and resilient building material developed over 500 million years of evolutionary history. It has manifested itself in wings, sails, horns, armor, and an even greater array of appendages since the time of its origin. In dinosaur fossils, skeletons are biological time capsules that tell us of lives we'll never see in the flesh. Inherited from a common fishy ancestor, it is the stuff that binds all of us vertebrates together into one great family. Swim, slither, stomp, fly, dig, run - all are expressions of what bones make possible. But that's hardly all. In The Secret Life of Bone, Brian Switek frames the history of our species through the importance of bone from instruments and jewellery, to objects of worship and conquest from the origins of religion through the genesis of science and up through this very day. While bone itself can reveal our individual stories, the truth very much depends on who's telling it. Our skeletons are as embedded in our culture as they are in our bodies. Switek, an enthusiastic osteological raconteur, cuts through biology, history, and culture to understand the meaning of what's inside us and what our bones tell us about who we are, where we came from and the legacies we leave behind.

Walking upright on two feet is a uniquely human skill. It defines us as a species. It enabled us to walk out of Africa and to spread as far as Alaska and Australia. It freed our hands and freed our minds. We put one foot in front of the other without thinking - yet how many of us know how we do that, or appreciate the advantages it gives us? In this hymn to walking, neuroscientist Shane O'Mara invites us to marvel at the benefits it confers on our bodies and minds. In Praise of Walking celebrates this miraculous ability. Incredibly, it is a skill that has its evolutionary origins millions of years ago, under the sea. And the latest research is only now revealing how the brain and nervous system performs the mechanical magic of balancing, navigating a crowded city, or running our inner GPS system. Walking is good for our muscles and posture; it helps to protect and repair organs, and can slow or turn back the ageing of our brains. With our minds in motion we think more creatively, our mood improves and stress levels fall. Walking together to achieve a shared purpose is also a social glue that has contributed to our survival as a species. As our lives become increasingly sedentary, we risk all this. We must start walking again, whether it's up a mountain, down to the park, or simply to school and work. We, and our societies, will be better for it.

`Inferior is more than just a book. It's a battle cry - and right now, it's having a galvanising effect on its core fanbase' Observer Are women more nurturing than men? Are men more promiscuous than women? Are males the naturally dominant sex? And can science give us an impartial answer to these questions? Taking us on an eye-opening journey through science, Inferior challenges our preconceptions about men and women, investigating the ferocious gender wars that burn in biology, psychology and anthropology. Angela Saini revisits the landmark experiments that have informed our understanding, lays bare the problem of bias in research, and speaks to the scientists finally exploring the truth about the female sex. The result is an enlightening and deeply empowering account of women's minds, bodies and evolutionary history. Interrogating what these revelations mean for us as individuals and as a society, Inferior unveils a fresh view of science in which women are included, rather than excluded.

'[A] beautifully written investigation of grief ... As an exploration of love and loss, as a portrait of a person and of the nature of personhood, this book is about as true as any I have read' James McConnachie, Sunday Times An audacious and beautiful account of grief and who we are. Memoir, neuroscience and myth interweave to create a book unlike any other When celebrated neuropsychologist Paul Broks' wife died of cancer, he found himself plunged into the world of the bereaved. As he experienced the pain, alienation and suffering that make us human, his clinician-self seemed to watch on with keen interest. He embarked upon a voyage of experience: a journey through grief, philosophy, consciousness, humanity and magical thinking - seen through the prism of a lifetime's work in neuroscience. Fusing an account of living with and recovering from loss with thought-provoking meditations on the nature of the mind and the self, The Darker the Night, the Brighter the Stars is an audacious and beautiful work by a writer of astonishing wisdom and compassion.

James Lovelock, creator of the Gaia hypothesis and the greatest environmental thinker of our time, has produced an astounding new theory about future of life on Earth. He argues that the anthropocene - the age in which humans acquired planetary-scale technologies - is, after 300 years, coming to an end. A new age - the novacene - has already begun. New beings will emerge from existing artificial intelligence systems. They will think 10,000 times faster than we do and they will regard us as we now regard plants - as desperately slow acting and thinking creatures. But this will not be the cruel, violent machine takeover of the planet imagined by sci-fi writers and film-makers. These hyper-intelligent beings will be as dependent on the health of the planet as we are. They will need the planetary cooling system of Gaia to defend them from the increasing heat of the sun as much as we do. And Gaia depends on organic life. We will be partners in this project. It is crucial, Lovelock argues, that the intelligence of Earth survives and prospers. He does not think there are intelligent aliens, so we are the only beings capable of understanding the cosmos. Maybe, he speculates, the novacene could even be the beginning of a process that will finally lead to intelligence suffusing the entire cosmos. At the age 100, James Lovelock has produced the most important and compelling work of his life.

Explore ecology in this accessible introduction to how the natural world works and how we have started to understand the environment, ecosystems, and climate change. Using a bold, graphic-led approach, The Ecology Book explores and explains over 85 of the key ideas, movements, and acts that have defined ecology and ecological thought. The book has a simple chronological structure, with early chapters ranging from the ideas of classical thinkers through to attempts by Enlightenment thinkers to systematically order the natural world. Later chapters trace the evolution of modern thinking, from the ideas of Thomas Malthus, Henry Thoreau, and others, right the way through to the political and scientific developments of the modern era, including the birth of the environmental movement and the Paris Agreement. The ideal introduction to one of the most important subjects of our time.

'Mind-blowing ... It is a hugely important book ... His story is crucial' Matt Ridley, The Times One of the world's top behavioural geneticists argues that we need a radical rethink about what makes us who we are The blueprint for our individuality lies in the 1% of DNA that differs between people. Our intellectual capacity, our introversion or extraversion, our vulnerability to mental illness, even whether we are a morning person - all of these aspects of our personality are profoundly shaped by our inherited DNA differences. In Blueprint, Robert Plomin, a pioneer in the field of behavioural genetics, draws on a lifetime's worth of research to make the case that DNA is the most important factor shaping who we are. Our families, schools and the environment around us are important, but they are not as influential as our genes. This is why, he argues, teachers and parents should accept children for who they are, rather than trying to mould them in certain directions. Even the environments we choose and the signal events that impact our lives, from divorce to addiction, are influenced by our genetic predispositions. Now, thanks to the DNA revolution, it is becoming possible to predict who we will become, at birth, from our DNA alone. As Plomin shows us, these developments have sweeping implications for how we think about parenting, education, and social mobility. A game-changing book by a leader in the field, Blueprint shows how the DNA present in the single cell with which we all begin our lives can impact our behaviour as adults.

A sober-minded philosophical exploration of what AI can and cannot achieve Humans may not be Earth (TM)s most intelligent species for much longer: the world chess, Go, and Jeopardy! champions are now all AIs. Given the rapid pace of progress in AI, many predict that AI could advance to human-level intelligence within the next several decades. From there, it could quickly outpace human intelligence. What do these developments mean for the future of the mind? In Artificial You, Susan Schneider urges that it is inevitable that AI will take intelligence in new directions, but it is up to us to carve out a sensible path forward. As AI technology turns inward, reshaping the brain, as well as outward, potentially creating machine minds, it is crucial to beware. Homo sapiens, as mind designers, will be playing with "tools" they do not understand how to use: the self, the mind, and consciousness. Schneider argues that an insufficient grasp of the nature of self, consciousness, and mind could undermine the use of AI and brain enhancement technology, bringing about the demise or suffering of conscious beings. To flourish, we must grasp the philosophical issues lying beneath the algorithms. At the heart of her exploration is a sober-minded discussion of what AI can truly achieve: Can robots really be conscious? Can we merge with AI, as tech leaders like Elon Musk and Ray Kurzweil, suggest? Is the mind just a program? Examining these thorny issues, Schneider proposes ways we can test for machine consciousness, questions whether consciousness is an unavoidable byproduct of sophisticated intelligence, and considers the overall dangers of creating machine minds.

'This is a book of miracles. Fascinating... An absorbing compendium of unlikely recoveries from physical and mental ailments offers evidence that the brain can heal... brings Oliver Sacks to mind' Lisa Appignanesi, Observer The Brain's Way of Healing explores the astonishing advances in the discovery of neuroplasticity, showing that the brain has its own unique way of healing, only recently uncovered. Norman Doidge discusses a series of remarkable recoveries: patients told they would never improve have years of chronic pain alleviated or damage from debilitating strokes undone, and symptoms of multiple sclerosis, Parkinson's disease, brain injury, autism or learning disorders are reversed. He also shows how the risk of dementia can be lowered by 60%. Using stories to present cutting-edge science, Doidge illustrates principles that everyone can apply to improve their brain's performance.

As read by James Corden, Fearne Cotton, Jim Chapman and Dougie Poytner. 'We have a responsibility, every one of us' David Attenborough Around 12.7 million tonnes of plastic are entering the ocean every year, killing over 1 million seabirds and 100,000 marine mammals. By 2050 there could be more plastic in the ocean than fish by weight. Plastic pollution is the environmental scourge of our age, but how can YOU make a difference? This accessible guide, written by the campaigner at the forefront of the anti-plastic movement, will help you make the small changes that make a big difference, from buying a reusable coffee cup to running a clean-up at your local park or beach. Tips on giving up plastic include: * Washing your clothes within a wash bag to catch plastic microfibers (the cause of 30% of plastic pollution in the ocean) * Replacing your regular shampoo with bar shampoo * How to lobby your supermarket to remove unnecessary packaging * How to throw a plastic-free birthday party * How to convince others to join you in giving up plastic Plastic is not going away without a fight. We need a movement made up of billions of individual acts, bringing people together from all backgrounds and all cultures, the ripples of which will be felt from the smallest village to the tallest skyscrapers. This is a call to arms - to join forces across the world and to end our dependence on plastic. #BreakFreeFromPlastic Plastic is not going away without a fight. We need a movement made up of billions of individual acts, bringing people together from all backgrounds and all cultures, the ripples of which will be felt from the smallest village to the tallest skyscrapers. 'Plastic waste is one of the greatest environmental challenges facing the world' Theresa May 'As Head of Oceans at Greenpeace, Will is on the front line of humanity's global fight against plastic. This timely book not only explains how we got into this mess, but most importantly offers an optimistic and proactive approach as to how we can get out of it'. - Richard Walker, Managing Director at Iceland

How to be Human is the only manual you need to help you upgrade your mind as much as you've upgraded your iphone. 'With this marvellous book, Ruby Wax has confirmed her position as one of the most readable, inspirational and engaging writers in the field of human mental health, happiness and fulfilment.' Stephen Fry "It took us 4 billion years to evolve to where we are now - completely brilliant and yet, some might say, emotionally dwarfed. The question is: can our more empathetic side catch up in time to save us and the world? I've got nothing against smarts, but it's smarts without emotional awareness that got us into this position of being able to nuke each other into oblivion and rape the earth for oil." With a little help from a monk (who tells us how our mind works) and a neuroscientist (who tells us how our brain works), Ruby Wax answers every question you've ever had about: evolution, thoughts, emotions, the body, addictions, relationships, sex, kids, the future and compassion. Filled with witty anecdotes from Ruby's own life, and backed up by smart science and practical mindfulness exercises, How to be Human is the only manual you need to help you upgrade your mind as much as you've upgraded your iphone. 'Ruby has beautifully fused neurology and spirituality and given us a means to cope with operating both a mind and a brain. If this mental upgrade works then all other books will become defunct as we repose in bliss.' Russell Brand 'How to Be Human is, without exaggeration, a lifeline; wise, practical and funny, it is a handbook for those in despair. It is actually for everyone alive, for the curious, or disillusioned or muddled or just plain happy.' Joanna Lumley

How do radically new kinds of organisms evolve? The Origin of Higher Taxa addresses this essential question, specifically whether the emergence of higher taxa such as orders, classes, and phyla are the result of normal Darwinian evolution acting over a sufficiently long period of time, or whether unusual genetic events and particular environmental and ecological circumstances are also involved. Until very recently, the combination of an incomplete fossil record and a limited understanding about how raw mutations lead via modified ontogenic processes to significant phenotypic changes, effectively stymied scientific debate. However, it is now timely to revisit the question in the light of the discovery of considerable new fossil material (and new techniques for studying it), together with significant advances in our understanding of phenotypic development at the molecular level. This novel text incorporates evidence from morphology, palaeobiology, developmental biology, and ecology, to review those parts of the fossil record that illustrate something of the pattern of acquisition of derived characters in lineages leading to actual higher taxa as well as the environmental conditions under which they occurred. The author's original ideas are set within the context of a broad and balanced review of the latest research in the field. The result is a book which provides a concise, authoritative, and accessible overview of this fascinating subject for both students and researchers in evolutionary biology and palaeontology.

Are we our brains? How can you map the mind? Can brain scans read our minds?Based on Rob Newman's live stand-up show and new BBC Radio 4 series, his thought-provoking new book explores the scientific breakthroughs that have turned received ideas of brain science upside down. After imagining volunteering for a brain-imaging experiment meant to locate the part of the brain that lights up when you're in love, comedian Robert Newman emerged with more questions than answers. In Neuropolis Newman argues that the current claim that the brain is just a complicated computer derives from science, but from a combination of philosophical stowaways and a version of evolutionary biology that owes little to Darwin. He questions why brain science is devoted to such a peculiarly reductionist world view, when really exciting advances in neuroscience go untold, such as awe-inspiring discoveries about the origins of memory in ancient oceans. He also shows that our brains are inextricably and profoundly intertwined with our bodies, the natural world and the world we have made, including hilarious accounts of his own participation in neurological experiments. Debunking the common, even brainless interpretations of brain science, he celebrates the more intriguing and underreported advances in neuroscience with zest and wit.
