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:
A groundbreaking exploration of the neuroscience of spirituality and a bold new paradigm for health, healing, and resilience. Whether it's meditation or a walk in nature, reading a sacred text or saying a prayer, there are many ways to tap into a heightened awareness of the world around us and our place in it. Lisa Miller draws on decades of clinical experience and award-winning research to show that humans are universally equipped with this capacity for spirituality, and that our brains become more resilient and robust as a result of it. Bringing scientific rigour to the most intangible aspect of our lives, Miller's counterintuitive findings reveal the measurable positive effects of spirituality: for better decision-making, a healthier brain and an inspired life. Brimming with inspiration and compassion, this landmark book revolutionizes our understanding of spirituality, mental health and how to find meaning and purpose in life.
A true-life scientific adventure story, this thrilling book takes the reader deep into South African caves to discover fossil remains that compel a monumental reframing of the human family tree. In the summer of 2022, Lee Berger lost 50 pounds in order to wriggle though impossibly small openings in the Rising Star cave complex in South Africa—spaces where his team has been unearthing the remains of Homo naledi, a proto-human likely to have coexisted with Homo sapiens some 250,000 years ago. The lead researcher on the site, still Berger had never made his way into the dark, cramped, dangerous underground spaces where many of the naledi fossils had been found. Now he was ready to do so. Once inside the cave, Berger made shocking new discoveries that expand our understanding of this early hominid—discoveries that stand to alter our fundamental understanding of what makes us human. So what does it all mean? Join Berger on the adventure of a lifetime as he explores the Rising Star cave system and begins the complicated process of explaining these extraordinary finds—finds that force a rethinking of human evolution, and discoveries that Berger calls “the Rosetta stone of the human mind.”
J.B.S. Haldane (1892-1964) is widely appreciated as one of the greatest and most influential British scientists of the 20th century, making significant contributions to genetics, physiology, biochemistry, biometry, cosmology, and other sciences. More remarkable, then, is the fact that Haldane had no formal qualification in science. He made frequent appearances in the media, making pronouncements on a variety of poignant topics including mining disasters, meteorites, politics, and the economy, and was a popular scientific essay writer. Haldane also was famed for conducting painful experiments on himself, including several instances in which he permanently himself. A staunch Marxist and convert to Hinduism, Haldane lived a diverse, lively and interesting life that is still revered by today's science community. A biography of Haldane has not been attempted since 1968, and that book provided an incomplete account of the man's scientific achievement. "The Life and Works of J.B.S. Haldane" serves to fix this glaring omission, providing a complete biographical sketch written by Krishna Dronamraju, one of the last living men to have worked personally with Haldane. A new genre of biographies of 20th-century scientists has come into being, and thus far works have been written about men like Einstein, Oppenheimer, Bernal, Galton, and many more; the inclusion of Haldane within this genre is an absolute necessity. Dronamraju evaluates Haldane's social and political background, as well as his scientific creativity and accomplishments. Haldane embodies a generation of intellectuals who believed and promoted knowledge for its own sake, and that spirit of scientific curiosity and passion is captured in this biography.
In the past few years, the subject of climate change has frequently garnered headlines due to the usual political controversy surrounding it. However, setting aside the argument as to whether climate change is a man-made effect or not, we cannot deny the fact that humanity has been discharging carbon increasingly into the atmosphere for centuries. Likewise, similar reports on the growing Great Pacific Garbage Patch-and the general accumulation of plastics everywhere-are alarming. Moreover, it has also been recently demonstrated that microplastics are finally entering the food webs which include the human consumer. Air, soil, and water pollution are increasing; in some ways forcing certain countries and governments to modify their politics, while also creating new opportunities and opening new niches for the marketing of products, such as air and water filters. With current techniques, it is not possible to completely eliminate all toxic and hazardous waste, which means that security deposits are necessary. Security deposits are storage areas prepared for certain toxic and dangerous industrial waste, so that its harmful properties cannot affect the natural environment and human health-at least, in any case, for a very long time. Due to their geomorphological composition, topography, and hydrographic conditions, there are sites that can be used as waste deposits, given their natural isolation and projected stability for hundreds of years. Thus, they become security deposits. In addition, every day new materials and construction techniques are developed that allow for a total isolation of the waste. A relatively new view in the material life cycle is the reuse of the generated waste as new resources. This helps to mitigate the cost increases in raw materials, energy, and regulations regarding waste disposal, which have caused the industry to rethink its production methods, leading to a better use of raw materials and energy. Clean technologies are those used by the industry to reduce the need for treatment or disposal of waste and to reduce the demand for raw materials, energy, and water. For the proper implementation of clean technologies, industries and municipalities must develop a deep understanding of their own processes and activities, and must analyze the characteristics of their equipment and make any possible modifications. An environmental evaluation of the situation provides suitable information on the efficiency of each component and its integration in the whole process, on the proportion of waste, on energy consumption, and on how to reorganize or modify to improve cost-efficiency in economic and environmental terms, which in a middle term view results in synergistic goals. With this concise introduction to the world of waste and pollutant treatment technologies, the editors believe it is clear that the solutions are to be developed on a case-by-case basis; because the larger the number of mixed pollutants, the more complex and intimated the process will be. This book presents a series of selected approaches that can be used to approach different cases, also depending upon budget and viability of a sustainable approach. This book serves as a source of information, triggers ideas, and fosters interaction between all the players taking action in sustainable development initiatives.

The Two Selves takes the position that the self is not a "thing" easily reduced to an object of scientific analysis. Rather, the self consists in a multiplicity of aspects, some of which have a neuro-cognitive basis (and thus are amenable to scientific inquiry) while other aspects are best construed as first-person subjectivity, lacking material instantiation. As a consequence of its potential immateriality, the subjective aspect of self cannot be taken as an object and therefore is not easily amenable to treatment by current scientific methods. Klein argues that to fully appreciate the self, its two aspects must be acknowledged, since it is only in virtue of their interaction that the self of everyday experience becomes a phenomenological reality. However, given their different metaphysical commitments (i.e., material and immaterial aspects of reality), a number of issues must be addressed. These include, but are not limited to, the possibility of interaction between metaphysically distinct aspects of reality, questions of causal closure under the physical, the principle of energy conservation, and more. After addressing these concerns, Klein presents evidence based on self-reports from case studies of individuals who suffer from a chronic or temporary loss of their sense of personal ownership of their mental states. Drawing on this evidence, he argues that personal ownership may be the factor that closes the metaphysical gap between the material and immaterial selves, linking these two disparate aspects of reality, thereby enabling us to experience a unified sense of self despite its underlying multiplicity.
A tightly argued and expansive examination of the pitfalls of transhumanism that reacquaints us with what it means to live well. Advocates of transhumanism, or "radical" enhancement, urge us to pursue the biotechnological heightening of select capacities - above all, cognitive ability - so far beyond any human limit that the beings with those capacities would exist on a higher ontological plane. For proponents of such views, humanity's self-transcendence through advancements in science and technology may even be morally required. Consequently, the human stakes of how we respond to transhumanism are immeasurably high. In Posthuman Bliss? The Failed Promise of Transhumanism, Susan B. Levin challenges transhumanists' overarching commitments regarding the mind and brain, ethics, liberal democracy, knowledge, and reality, showing their notion of humanity's self-transcendence into "posthumanity" to be little more than fantasy. Uniting philosophical with scientific arguments, Levin mounts a significant challenge to transhumanists' claim that science and technology support their vision of posthumanity. In a clear and engaging style, she dismantles transhumanists' breezy assurances that posthumans will emerge if we but allocate sufficient resources to that end. Far from offering theoretical and practical "proof of concept" for the vision that they urge upon us, Levin argues, transhumanists engage inadequately with cognitive psychology, biology, and neuroscience, often relying on questionable or outdated views within those fields. Having shown in depth why transhumanism should be rejected, Levin argues forcefully for a holistic perspective on living well that is rooted in Aristotle's virtue ethics but that is adapted to liberal democracy. This holism is thoroughly human, in the best of senses: It directs us to consider worthy ends for us as human beings and to do the irreplaceable work of understanding ourselves rather than relying on technology and science to be our salvation.
Why do people find monkeys and apes so compelling to watch? One clear answer is that they seem so similar to us-a window into our own minds and how we have evolved over millennia. As Charles Darwin wrote in his Notebook, "He who understands baboon would do more toward metaphysics than Locke." Darwin recognized that behavior and cognition, and the neural architecture that support them, evolved to solve specific social and ecological problems. Defining these problems for neurobiological study, and conveying neurobiological results to ethologists and psychologists, is fundamental to an evolutionary understanding of brain and behavior. The goal of this book is to do just that. It collects, for the first time in a single book, information on primate behavior and cognition, neurobiology, and the emerging discipline of neuroethology. Here leading scientists in several fields review work ranging from primate foraging behavior to the neurophysiology of motor control, from vocal communication to the functions of the auditory cortex. The resulting synthesis of cognitive, ethological, and neurobiological approaches to primate behavior yields a richer understanding of our primate cousins that also sheds light on the evolutionary development of human behavior and cognition.
In 2005, The Millennium Ecosystem Assessment (MA) provided the
first global assessment of the world's ecosystems and ecosystem
services. It concluded that recent trends in ecosystem change
threatened human wellbeing due to declining ecosystem services.
This bleak prophecy has galvanized conservation organizations,
ecologists, and economists to work toward rigorous valuations of
ecosystem services at a spatial scale and with a resolution that
can inform public policy.
For over thirty years Susan Wolf has been writing about moral and nonmoral values and the relation between them. This volume collects Wolf's most important essays on the topics of morality, love, and meaning, ranging from her classic essay "Moral Saints" to her most recent "The Importance of Love." Wolf's essays warn us against the common tendency to classify values in terms of a dichotomy that contrasts the personal, self-interested, or egoistic with the impersonal, altruistic or moral. On Wolf's view, this tendency ignores or distorts the significance of such values as love, beauty, and truth, and neglects the importance of meaningfulness as a dimension of the good life. These essays show us how a self-conscious recognition of the variety of values leads to new understandings of the point, the content, and the limits of morality and to new ways of thinking about happiness and well-being.
Despite the massive scale of global inequalities, until recently few political philosophers or bioethicists addressed their ethical implications. Questions of justice were thought to be primarily internal to the nation state. Over the last decade or so, there has been an explosion of interest in the philosophical issues surrounding global justice. These issues are of direct relevance to bioethics. The links between poverty and health imply that we cannot separate questions of global health from questions about fair distribution of global resources and the institutions governing the world order. Similarly, as increasing numbers of medical trials are conducted in the developing world, researchers and their sponsors have to confront the special problems of doing research in an unjust world, with corresponding obligations to correct injustice and avoid exploitation. This book presents a collection of original essays by leading thinkers in political theory, philosophy, and bioethics. They address the key issues concerning global justice and bioethics from two perspectives. The first is ideal theory, which is concerned with the social institutions that would regulate a just world. What is the relationship between human rights and the provision of health care? How, if at all, should a global order distinguish between obligations to compatriots and others? The second perspective is from non-ideal theory, which governs how people should behave in the unjust world in which we actually find ourselves. What sort of medical care should actual researchers working in impoverished countries offer their subjects? What should NGOs do in the face of cultural practices with which they deem unethical? If coordinated international action will not happen, what ought individual states to do? These questions have more than theoretical interest; their answers are of direct practical import for policymakers, researchers, advocates, NGOs, scholars, and others. This book is the first collection to comprehensively address the intersection of global justice and bioethical dilemmas.
While scholars typically view Plato's engagement with medicine as uniform and largely positive, Susan B. Levin argues that from the Gorgias through the Laws, his handling of medicine unfolds in several key phases. Further, she shows that Plato views medicine as an important rival for authority on phusis (nature) and eudaimonia (flourishing). Levin's arguments rest on careful attention both to Plato and to the Hippocratic Corpus. Levin shows that an evident but unexpressed tension involving medicine's status emerges in the Gorgias and is explored in Plato's critiques of medicine in the Symposium and Republic. In the Laws, however, this rivalry and tension dissolve. Levin addresses the question of why Plato's rivalry with medicine is put to rest while those with rhetoric and poetry continue. On her account, developments in his views of human nature, with their resulting impact on his political thought, drive Plato's striking adjustments involving medicine in the Laws. Levin's investigation of Plato is timely: for the first time in the history of bioethics, the value of ancient philosophy is receiving notable attention. Most discussions focus on Aristotle's concept of phronesis (practical wisdom); here, Levin argues that Plato has much to offer bioethics as it works to address pressing concerns about the doctor-patient tie, medical professionalism, and medicine's relationship to society.
In the last fifteen years, there has been significant interest in studying the brain structures involved in moral judgments using novel techniques from neuroscience such as functional magnetic resonance imaging (fMRI). Many people, including a number of philosophers, believe that results from neuroscience have the potential to settle seemingly intractable debates concerning the nature, practice, and reliability of moral judgments. This has led to a flurry of scientific and philosophical activities, resulting in the rapid growth of the new field of moral neuroscience. There is now a vast array of ongoing scientific research devoted towards understanding the neural correlates of moral judgments, accompanied by a large philosophical literature aimed at interpreting and examining the methodology and the results of this research. This is the first volume to take stock of fifteen years of research of this fast-growing field of moral neuroscience and to recommend future directions for research. It features the most up-to-date research in this area, and it presents a wide variety of perspectives on this topic.
Levels of mycotoxin contamination in agricultural commodities are
regulated in more than 100 countries, and exposure to these
naturally occurring toxins presents serious risks to the health of
humans and animals with negative impacts to commodity values. This
symposium series book presents significant scientific developments
in the multifaceted approach to reducing exposure to these
naturally occurring toxins. A broad-spectrum of subject matter of
the multidisciplinary field of mycotoxin research is conveniently
compiled in this single volume, and general themes include
prevention, control, exposure, molecular biology, biosynthesis,
analytical methodology, and emerging techniques. The book opens
with an overview of prevention of mycotoxin production by means of
biological control and human exposure to contaminated foods,
including tofu, apples, figs, and a broad range of fruits.
Although we no longer live in the relative simplicity of the
Jurassic age, and even though we are not aware of them, primitive
mammalian brain that developed in that era still live on inside our
skulls and remain crucial to our daily functions. The challenges we
face today in the information age--how to process the vastly
greater, more varied and quickly changing inputs we receive--are
very different from those that our ancestors faced during the
Jurassic age. As we struggle to process overwhelming amounts of
information, we may sometimes ask whether our brains can change to
help us adapt. In fact, our brains have always changed gradually,
so the questions we should ask are really how our brains will
change, and whether we will be able to take full advantage of the
changes, perhaps even enhance them, to help us keep up with the
accelerating evolution of machines. To understand how our brains
will change, we need to understand how they evolved in the first
place, as well as how the interactions of the resulting brain
structures, including the relics of primitive mammalian and even
reptilian processes, influence how we think and act.
A new theory is taking hold in neuroscience. It is the theory that the brain is essentially a hypothesis-testing mechanism, one that attempts to minimise the error of its predictions about the sensory input it receives from the world. It is an attractive theory because powerful theoretical arguments support it, and yet it is at heart stunningly simple. Jakob Hohwy explains and explores this theory from the perspective of cognitive science and philosophy. The key argument throughout The Predictive Mind is that the mechanism explains the rich, deep, and multifaceted character of our conscious perception. It also gives a unified account of how perception is sculpted by attention, and how it depends on action. The mind is revealed as having a fragile and indirect relation to the world. Though we are deeply in tune with the world we are also strangely distanced from it. The first part of the book sets out how the theory enables rich, layered perception. The theory's probabilistic and statistical foundations are explained using examples from empirical research and analogies to different forms of inference. The second part uses the simple mechanism in an explanation of problematic cases of how we manage to represent, and sometimes misrepresent, the world in health as well as in mental illness. The third part looks into the mind, and shows how the theory accounts for attention, conscious unity, introspection, self and the privacy of our mental world.
Cognitive psychology has matured and flourished in the last half-century, as new theories, research tools, and theoretical frameworks have allowed cognitive psychologists and researchers to explore a broad array of topics. In the same vein, the depth of understanding and the methodological and theoretical sophistication have also grown in wonderful ways. Given the expanse of the field, an up-to-date and inclusive resource such as this handbook is needed for aspiring generalists who wish to read the book cover to cover, and for the many readers who are simply curious to know the current happenings in other cognition laboratories. Guided by this need, this volume's 64 chapters cover all aspects of cognition, spanning perceptual issues, attention, memory, knowledge representation, language, emotional influences, judgment, problem solving, and the study of individual differences in cognition. Additional chapters turn to the control of complex actions and the social, cultural, and developmental context of cognition. The authors include a mix of well-established influential figures and younger colleagues in order to gain an understanding of the field's forward trajectory. The volume also includes a mix of "tutorial" chapters and chapters that powerfully represent a particular research team's point of view.
Recent years have seen the rise of a remarkable partnership between
the social and computational sciences on the phenomena of emotions.
Rallying around the term Affective Computing, this research can be
seen as revival of the cognitive science revolution, albeit garbed
in the cloak of affect, rather than cognition. Traditional
cognitive science research, to the extent it considered emotion at
all, cases it as at best a heuristic but more commonly a harmful
bias to cognition. More recent scholarship in the social sciences
has upended this view.
Our ability to map and intervene in the structure of the human
brain is proceeding at a very quick rate. Advances in psychiatry,
neurology, and neurosurgery have given us fresh insights into the
neurobiological basis of human thought and behavior. Technologies
like MRI and PET scans can detect early signs of psychiatric
disorders before they manifest symptoms. Electrical and magnetic
stimulation of the brain can non-invasively relieve symptoms of
obsessive-compulsive disorder, depression and other conditions
resistant to treatment, while implanting neuro-electrodes can help
patients with Parkinsons and other motor control-related diseases.
New drugs can help regenerate neuronal connections otherwise
disrupted by schizophrenia and similar diseases.
Unfit for the Future argues that the future of our species depends on our urgently finding ways to bring about radical enhancement of the moral aspects of our own human nature. We have rewritten our own moral agenda by the drastic changes we have made to the conditions of life on earth. Advances in technology enable us to exercise an influence that extends all over the world and far into the future. But our moral psychology lags behind and leaves us ill equipped to deal with the challenges we now face. We need to change human moral motivation so that we pay more heed not merely to the global community, but to the interests of future generations. It is unlikely that traditional methods such as moral education or social reform alone can bring this about swiftly enough to avert looming disaster, which would undermine the conditions for worthwhile life on earth forever. Persson and Savulescu maintain that it is likely that we need to explore the use of new technologies of biomedicine to change the bases of human moral motivation. They argue that there are in principle no philosophical or moral objections to such moral bioenhancement. Unfit for the Future? challenges us to rethink our attitudes to our own human nature, before it is too late.
In The Intelligent Movement Machine: An Ethological Perspective on the Primate Motor System, Michael Graziano offers a fundamentally new theory of motor cortex organization: the rendering of the movement repertoire onto the cortex. The action repertoire of an animal is highly dimensional, whereas the cortical sheet is two-dimensional. Rendering the action space onto the cortex therefore results in a complex pattern, explaining the otherwise inexplicable details of the motor cortex organization. This clearly written book book includes a complete history of motor cortex research from its discovery to the present, a discussion of the major issues in motor cortex research, and an account of recent experiments that led to Graziano's "action map" view. Though focused on the motor cortex, the book includes a range of topics from an explanation of how primates put food in their mouths, to the origins of social beahvior such as smiling and laughing, to the mysterious link between movement disorders and autism. This book is written for a general audience, and should be of interest to experts, students, and the scientific lay.
During the past two decades international collaborative studies
have yielded extensive information on genome sequences, genome
architecture and their variations. The challenge we now face is to
understand how these variations impact structure and function of
organelles, physiological systems and phenotype. The goal of this
book is to present steps in the pathways of exploration to connect
genotype to phenotype and to consider how alterations in genomes
impact disease.
Ethicists and psychologists have become increasingly interested in the development of virtue in recent years, approaching the topic from the perspectives of virtue ethics and developmental psychology respectively. Such interest in virtue development has spread beyond academia, as teachers and parents have increasingly striven to cultivate virtue as part of education and child-rearing. Looking at these parallel trends in the study and practice of virtue development, the essays in this volume explore such questions as: How can philosophical work on virtue development inform psychological work on it, and vice versa? How should we understand virtue as a dimension of human personality? What is the developmental foundation of virtue? What are the evolutionary aspects of virtue and its development? How is virtue fostered? How is virtue exemplified in behavior and action? How is our conception of virtue influenced by context and by developmental and social experiences? What are the tensions, impediments and prospects for an integrative field of virtue study? Rather than centering on each discipline, the essays in this volume are orgnaized around themes and engage each other in a broader dialogue. The volume begins with an introductory essay from the editors that explains the full range of philosophical and empirical issues that have surrounded the notion of virtue in recent years. |
