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.

It's been said that, after 9/11, the 2008 financial crash and the Covid-19 pandemic, we're a more fearful society than ever before. Yet fear, and the panic it produces, have long been driving forces - perhaps THE driving force - of world history: fear of God, of famine, war, disease, poverty, and other people. In Fear: An Alternative History of the World, Robert Peckham considers the impact of fear in history, as both a coercive tool of power and as a catalyst for social change.

Beginning with the Black Death in the fourteenth century, Peckham traces a shadow history of fear. He takes us through the French Revolution and the social movements of the nineteenth century to modern market crashes, Cold War paranoia and the AIDS pandemic, into a digital culture increasingly marked by uniquely twenty-first-century fears.

What did fear mean to us in the past, and how can a better understanding of it equip us to face the future? As Peckham demonstrates, fear can challenge as well as cement authority. Some crises have destroyed societies; others have been the making of them. Through the stories of the people and the moments that changed history, Fear: An Alternative History of the World reveals how fear and panic made us who we are.

Known as the `four horsemen' of New Atheism, these four big thinkers of the twenty-first century met only once. Their electrifying examination of ideas on this remarkable occasion was intense and wide-ranging. Everything that was said as they agreed and disagreed with one another, interrogated ideas and exchanged insights - about religion and atheism, science and sense - speaks with urgency to our present age.

Questions they asked of each other included:

• Is it ever possible to win a war of ideas?
• Is spirituality the preserve of the religious?
• Are there any truths you would rather not know?
• Would you want to see the end of faith?

The dialogue was recorded, and is now transcribed and presented here with new introductions from the surviving three horsemen. With a sparkling introduction from Stephen Fry, it makes essential reading for all their admirers and for anyone interested in exploring the tensions between faith and reason.

The story of YouTube, the global phenomenon which single-handedly upended traditional media and transformed Google into one of the world's most profitable companies.

Since 2005, YouTube has exploded, giving a platform to unique and valuable voices, but also to propaganda, misinformation and illicit videos. The algorithm which determines whether a channel lives or dies - how or when videos are seen, and how much creators earn through advertising - is notoriously secretive, remaining a mystery to consumers and broadcasters alike. At the same time, the site is massively profitable for parent company Google, helping turn it into one of the most influential powers on the planet.

In Like, Comment, Subscribe, Bloomberg tech journalist Mark Bergen delivers the definitive account on YouTube, detailing how it started, how it works and ultimately how it drives Google's success. It can be seen as the story of a technical marvel that has upended traditional media and created stars out of everyday people, or the story of the rise of a ruthless advertising conglomerate with little regard for its impact on the world beyond the bottom line - but in reality, it's the story of both.

There is an invisible weapon among us. By the time you know you are a victim, it has turned you into a killer. A compelling, fast-paced, ticking clock non-fiction thriller from the author of the bestselling Nuclear War: A Scenario.

A lab accident, a bio-attack, a global pandemic, and the collapse of human society. In this explosive new book, based on dozens of new interviews with experts with high-level political, governmental, medical, and military responsibility, Annie Jacobsen examines this very scenario.

There is no mushroom cloud, no shock wave or blast. Instead, the scenario that could end the world as we know it begins with something so small and malicious, that when used for evil, only evil can result.

This is what could happen; a roadmap to the hours, days, and weeks following the release of a biological agent, that serves as the most essential, forward-looking journalism in preparation for urgent societal upheaval.

Science is the most reliable means available for understanding the world around us and our place in it. But, since science draws conclusions based on limited empirical evidence, there is always a chance that a scientific inference will be incorrect. That chance, known as inductive risk, is endemic to science. Though inductive risk has always been present in scientific practice, the role of values in responding to it has only recently gained extensive attention from philosophers, scientists, and policy-makers. Exploring Inductive Risk brings together a set of eleven concrete case studies with the goals of illustrating the pervasiveness of inductive risk, assisting scientists and policymakers in responding to it, and moving theoretical discussions of this phenomenon forward. The case studies range over a wide variety of scientific contexts, including the drug approval process, high energy particle physics, dual-use research, climate science, research on gender disparities in employment, clinical trials, and toxicology. The book includes an introductory chapter that provides a conceptual introduction to the topic and a historical overview of the argument that values have an important role to play in responding to inductive risk, as well as a concluding chapter that synthesizes important themes from the book and maps out issues in need of further consideration.

That the longstanding antagonism between science and religion is irreconcilable has been taken for granted. And in the wake of recent controversies over teaching intelligent design and the ethics of stem-cell research, the divide seems as unbridgeable as ever.
In Science vs. Religion, Elaine Howard Ecklund investigates this unexamined assumption in the first systematic study of what scientists actually think and feel about religion. In the course of her research, Ecklund surveyed nearly 1,700 scientists and interviewed 275 of them. She finds that most of what we believe about the faith lives of elite scientists is wrong. Nearly 50 percent of them are religious. Many others are what she calls "spiritual entrepreneurs," seeking creative ways to work with the tensions between science and faith outside the constraints of traditional religion. The book centers around vivid portraits of 10 representative men and women working in the natural and social sciences at top American research universities. Ecklund's respondents run the gamut from Margaret, a chemist who teaches a Sunday-school class, to Arik, a physicist who chose not to believe in God well before he decided to become a scientist. Only a small minority are actively hostile to religion. Ecklund reveals how scientists-believers and skeptics alike-are struggling to engage the increasing number of religious students in their classrooms and argues that many scientists are searching for "boundary pioneers" to cross the picket lines separating science and religion.
With broad implications for education, science funding, and the thorny ethical questions surrounding stem-cell research, cloning, and other cutting-edge scientific endeavors, Science vs. Religion brings a welcome dose of reality to the science and religion debates.

An exciting challenge to how the internet and ICT have been understood in academia and popular culture and shows how important cultural assumptions are in how we understand technology. The Internet, Power and Society argues that the way in which we view technology such as the internet owes much to older, historic views of the media and to issues in contemporary society. Such perspectives are deeply rooted in a Western view of technology and the book concludes by offering a radically new perspective as to how the internet can change a society that is truly global in its application.
An original approach to ICT and the Internet that challenges the orthodoxyVery topical subject matter - the book addresses many of the issues regarded of key import in high level political discussions (such as the World Summit on the Information Society); the current understanding of ICT and how to move beyond this interpretationAn approach that moves the debate forward and offers a truly global way of understanding the Internet and ICT"

After centuries of neglect, the ethics of food are back with a vengeance. Justice for food workers and small farmers has joined the rising tide of concern over the impact of industrial agriculture on food animals and the broader environment, all while a global epidemic of obesity-related diseases threatens to overwhelm modern health systems. An emerging worldwide social movement has turned to local and organic foods, and struggles to exploit widespread concern over the next wave of genetic engineering or nanotechnologies applied to food. Paul B. Thompson's book applies the rigor of philosophy to key topics in the first comprehensive study explore interconnections hidden deep within this welter of issues. Bringing more than thirty years of experience working closely with farmers, agricultural researchers and food system activists to the topic, he explores the eclipse of food ethics during the rise of nutritional science, and examines the reasons for its sudden re-emergence in the era of diet-based disease. Thompson discusses social injustice in the food systems of developed economies and shows how we have missed the key insights for understanding food ethics in the developing world. His discussions of animal production and the environmental impact of agriculture breaks new ground where most philosophers would least expect it. By emphasizing the integration of these issues, Thompson not only brings a comprehensive philosophical approach to moral issues in the production, processing, distribution, and consumption of food - he introduces a fresh way to think about practical ethics that will have implications in other areas of applied philosophy.

This volume consists of written chapters taken from the presentations at the symposium "100+ Years of Plastics: Leo Baekeland and Beyond," held March 22, 2010, at the 239th ACS National Meeting in San Francisco. The symposium celebrates the 100th anniversary of the formation of General Bakelite Corp., which was preceded by Leo Baekland's synthesis of Bakelite in 1907 and the unveiling of the Bakelite process in 1909. It is quite reasonable to use the synthesis of Bakelite as the starting point of the Age of Plastics. Indeed, Time magazine in its June 14, 1999, issue on the 100 most influential people of the 20th century chose Leo Baekeland and his Bakelite synthesis as the sole representative of chemistry.
Leo Baekeland and Bakelite are the topics of the first four chapters of this volume. The first two chapters come from the perspective of Baekeland family members. Carl Kaufmann is related to the Baekeland family through marriage and is the author of the only full-length biography of Baekeland, published as a master's thesis from the University of Delaware. As a family member Kaufmann had access to all of Baekeland's papers. This first chapter (Leo H. Baekeland) is not only a biographical sketch, but an exploration of Baekeland's effect on the chemical industry. Hugh Karraker is Baekeland's great-grandson, and his chapter (A Portrait of Leo H. Baekeland) provides a family picture of the great inventor. Gary Patterson's chapter (Materia Polymerica: Bakelite) goes into the history of Bakelite chemistry, while Burkhard Wagner's contribution (Leo Baekeland's Legacy-100 Years of Plastics) covers the history of Bakelite manufacture through time and space, finishing with a description of another Baekeland legacy, the Baekeland Award given through the North Jersey Section of the ACS.
In later chapters, Les Sperling (History of Interpenetrating Polymer Networks Starting with Bakelite-Based Compositions) covers the improvements in interpenetrating networks. James Economy and Z. Parkar (Historical Perspectives on Phenolic Resins and High-Temperature Aromatic Polyesters of p-Hydroxybenzoic Acid and Their Copolyesters) follow the paths of resoles, novolaks, and related chemicals.

The powerful potential of digital media to engage citizens in political actions has now crossed our news screens many times. But scholarly focus has tended to be on "networked," anti-institutional forms of collective action, to the neglect of advocacy and service organizations. This book investigates the changing fortunes of the citizen-civil society relationship by exploring how social changes and innovations in communication technology are transforming the information expectations and preferences of many citizens, especially young citizens. In doing so, it is the first work to bring together theories of civic identity change with research on civic organizations. Specifically, it argues that a shift in "information styles" may help to explain the disjuncture felt by many young people when it comes to institutional participation and politics. The book theorizes two paradigms of information style: a dutiful style, which was rooted in the society, communication system and citizen norms of the modern era, and an actualizing style, which constitutes the set of information practices and expectations of the young citizens of late modernity for whom interactive digital media are the norm. Hypothesizing that civil society institutions have difficulty adapting to the norms and practices of the actualizing information style, two empirical studies apply the dutiful/actualizing framework to innovative content analyses of organizations' online communications-on their websites, and through Facebook. Results demonstrate that with intriguing exceptions, most major civil society organizations use digital media more in line with dutiful information norms than actualizing ones: they tend to broadcast strategic messages to an audience of receivers, rather than encouraging participation or exchange among an active set of participants. The book concludes with a discussion of the tensions inherent in bureaucratic organizations trying to adapt to an actualizing information style, and recommendations for how they may more successfully do so.

Artificial intelligence (AI) is often discussed as something extraordinary, a dream-or a nightmare-that awakens metaphysical questions on human life. Yet far from a distant technology of the future, the true power of AI lies in its subtle revolution of ordinary life. From voice assistants like Siri to natural language processors, AI technologies use cultural biases and modern psychology to fit specific characteristics of how users perceive and navigate the external world, thereby projecting the illusion of intelligence. Integrating media studies, science and technology studies, and social psychology, Deceitful Media examines the rise of artificial intelligence throughout history and exposes the very human fallacies behind this technology. Focusing specifically on communicative AIs, Natale argues that what we call "AI" is not a form of intelligence but rather a reflection of the human user. Using the term "banal deception," he reveals that deception forms the basis of all human-computer interactions rooted in AI technologies, as technologies like voice assistants utilize the dynamics of projection and stereotyping as a means for aligning with our existing habits and social conventions. By exploiting the human instinct to connect, AI reveals our collective vulnerabilities to deception, showing that what machines are primarily changing is not other technology but ourselves as humans. Deceitful Media illustrates how AI has continued a tradition of technologies that mobilize our liability to deception and shows that only by better understanding our vulnerabilities to deception can we become more sophisticated consumers of interactive media.

In a groundbreaking examination of the antislavery origins of liberal Protestantism, Molly Oshatz contends that the antebellum slavery debates forced antislavery Protestants to adopt an historicist understanding of truth and morality. Unlike earlier debates over slavery, the antebellum slavery debates revolved around the question of whether or not slavery was a sin in the abstract. Unable to use the letter of the Bible to answer the proslavery claim that slavery was not a sin in and of itself, antislavery Protestants, including William Ellery Channing, Francis Wayland, Moses Stuart, Leonard Bacon, and Horace Bushnell, argued that biblical principles opposed slavery and that God revealed slavery's sinfulness through the gradual unfolding of these principles. Although they believed that slavery was a sin, antislavery Protestants' sympathy for individual slaveholders and their knowledge of the Bible made them reluctant to denounce all slaveholders as sinners. In order to reconcile slavery's sinfulness with their commitments to the Bible and to the Union, antislavery Protestants defined slavery as a social rather than an individual sin. Oshatz demonstrates that the antislavery notions of progressive revelation and social sin had radical implications for Protestant theology. Oshatz carries her study through the Civil War to reveal how emancipation confirmed for northern Protestants the antislavery notion that God revealed His will through history. She describes how after the war, a new generation of liberal theologians, including Newman Smyth, Charles Briggs, and George Harris, drew on the example of antislavery and emancipation to respond to evolution and historical biblical criticism. The theological innovations rooted in the slavery debates came to fruition in liberal Protestantism's acceptance of the historical and evolutionary nature of religious truth.

An examination of the ways that digital technologies play an increasingly important role in the lives of precarious workers, far beyond the gig economy apps like Uber and Lyft. Over the past three decades, digital technologies like smartphones and laptops have transformed the way we work in the US. At the same time, workers at both ends of the income ladder have experienced rising levels of job insecurity and anxiety about their economic futures. In Left to Our Own Devices, Julia Ticona explores the ways that workers use their digital technologies to navigate insecure and flexible labor markets. Through 100 interviews with high and low-wage precarious workers across the US, she explores the surprisingly similar "digital hustles" they use to find work and maintain a sense of dignity and identity. Ticona then reveals how the digital hustle ultimately reproduces inequalities between workers at either end of polarized labor markets. A moving and accessible look at the intimate consequences of contemporary capitalism, Left to Our Own Devices will be of interest to sociologists, communication and media studies scholars, as well as a general audience of readers interested in digital technologies, inequality, and the future of work in the US.

The role of chance changed in the nineteenth century, and American literature changed with it. Long dismissed as a nominal concept, chance was increasingly treated as a natural force to be managed but never mastered. New theories of chance sparked religious and philosophical controversies while revolutionizing the sciences as probabilistic methods spread from mathematics, economics, and sociology to physics and evolutionary biology. Chance also became more visible in everyday life as Americans struggled to control its power through weather forecasting, insurance, game theory, statistics, military science, and financial strategy. Uncertain Chances shows how the rise of chance shaped the way nineteenth-century American writers faced questions of doubt and belief. Poe in his detective fiction critiques probabilistic methods. Melville in Moby-Dick and beyond struggles to vindicate moral action under conditions of chance. Douglass and other African American authors fight against statistical racism. Thoreau learns to appreciate the play between nature's randomness and order. Dickinson works faithfully to render poetically the affective experience of chance-surprise. These and other nineteenth-century writers dramatize the inescapable dangers and wonderful possibilities of chance. Their writings even help to navigate extremes that remain with us today-fundamentalism and relativism, determinism and chaos, terrorism and risk-management, the rational confidence of the Enlightenment and the debilitating doubts of modernity.

Emerging technologies present a challenging but fascinating set of ethical, legal and regulatory issues. The articles selected for this volume provide a broad overview of the most influential historical and current thinking in this area and show that existing frameworks are often inadequate to address new technologies - such as biotechnology, nanotechnology, synthetic biology and robotics - and innovative new models are needed. This collection brings together invaluable, innovative and often complementary approaches for overcoming the unique challenges of emerging technology ethics and governance.

In recent decades there has been an explosion in work in the social and physical sciences describing the similarities between human and nonhuman as well as human and non-animal thinking. This work has explicitly decentered the brain as the sole, self-contained space of thought, and it has found thinking to be an activity that operates not only across bodies but also across bodily or cellular membranes, as well as multifaceted organic and inorganic environments. For example, researchers have looked at the replication and spread of slime molds (playfully asking what would happen if they colonized the earth) to suggest that they exhibit 'smart behavior' in the way they move as a potential way of considering the spread of disease across the globe. Other scholars have applied this model of non-human thought to the reach of data mining and global surveillance. In The Biopolitics of Alphabets and Embryos, Ruth Miller argues that these types of phenomena are also useful models for thinking about the growth, reproduction, and spread of political thought and democratic processes. Giving slime, data and unbounded entities their political dues, Miller stresses their thinking power and political significance and thus challenges the anthropocentrism of mainstream democratic theories. Miller emphasizes the non-human as highly organized, systemic and productive of democratic growth and replication. She examines developments such as global surveillance, embryonic stem cell research, and cloning, which have been characterized as threats to the privacy, dignity, and integrity of the rational, maximizing and freedom-loving democratic citizen. By shifting her level of analysis from the politics of self-determining subjects to the realm of material environments and information systems, Miller asks what might happen if these alternative, nonhuman thought processes become the normative thought processes of democratic engagement.

Biomedical ethics is a burgeoning academic field with complex and far-reaching consequences. Whereas in Western secular bioethics this subject falls within larger ethical theories and applications (utilitarianism, deontology, teleology, and the like), Islamic biomedical ethics has yet to find its natural academic home in Islamic studies.
In this pioneering work, Abdulaziz Sachedina - a scholar with life-long academic training in Islamic law - relates classic Muslim religious values to the new ethical challenges that arise from medical research and practice. He depends on Muslim legal theory, but then looks deeper than juridical practice to search for the underlying reasons that determine the rightness or wrongness of a particular action. Drawing on the work of diverse Muslim theologians, he outlines a form of moral reasoning that can derive and produce decisions that underscore the spirit of the Shari'a. These decisions, he argues, still leave room to revisit earlier decisions and formulate new ones, which in turn need not be understood as absolute or final. After laying out this methodology, he applies it to a series of ethical questions surrounding the human life-cycle from birth to death, including such issues as abortion, euthanasia, and organ donation.
The implications of Sachedina's work are broad. His writing is unique in that it aims at conversing with Jewish and Christian ethics, moving beyond the Islamic fatwa literature to search for a common language of moral justification and legitimization among the followers of the Abrahamic traditions. He argues that Islamic theological ethics be organically connected with the legal tradition of Islam to enable it to sit in dialogue with secular and scripture-based bioethics in other faith communities. A breakthrough in Islamic bioethical studies, this volume is welcome and long-overdue reading for anyone interested in facing the difficult questions posed by modern medicine not only to the Muslim faithful but to the ethically-minded at large.

Originally published in 1988, Jon Roberts's book provided the first comprehensive analytical overview of public dialogue among nineteenth-century American Protestant intellectuals who struggled with the theory of organic evolution. Before the publication of Darwin's Origin of Species in 1859, most American Protestant intellectuals valued science, especially natural history, for supplying data that appeared to be invaluable for defending many major tenets of the Christian worldview. Arguments over the scientific merits of Darwin's theory gave way to discussions of its theological implications. Roberts's book reconstructs the course of that conversation from 1875 to 1900.

The Future of the Disabled in Liberal Society questions developments in human genetic research from the perspective of persons with mental disabilities and their families. Hans S. Reinders argues that when we use terms such as "disease" and "defect" to describe conditions that genetic engineering might well eliminate, we may also be assuming that disabled lives are deplorable and horrific. Reinders points out that the possibility of preventing disabled lives is at odds with our commitment to the full inclusion of disabled citizens in society. The tension between these different perspectives is of concern to all of us as genetic testing procedures proliferate. Reinders warns that preventative uses of human genetics might even become a threat to the social security and welfare benefits that help support disabled persons and their families. Reinders also argues that this conflict cannot be resolved or controlled on the level of public morality. Because a liberal society makes a commitment to individual freedom and choice, its members can consider the diagnostic and therapeutic uses of human genetics as options available to individual citizens. A liberal society will defend reproductive freedom as a matter of principle. Citizens may select their offspring in accord with their own personal values. Reinders concludes that the future of the mentally disabled in liberal society will depend on the strength of our moral convictions about the value of human life, rather than on the protective force of liberal morality. One of the most important aspects of this book is Reinder's attention to parents who have come to see the task of raising a disabled child as an enriching experience. These are people who change their conceptions of success and control and, therefore, their conceptions of themselves. They come to value their disabled children for what they have to give. Even though disabled children and disabled adults present parents and society with real challenges, the rewards are just as real. This powerful critique of contemporary bioethics is sure to become required reading for those interested in human development, special education, ethics, philosophy, and theology.

Bishop Harvey Spencer never thought he'd witness a pandemic-just as he never expected to see the election of a Black president, the election of a female vice president (Black or otherwise), or an insurrection. But all of those things have happened, and our lives have been forever altered. In this book, he seeks to discover what God is trying to reveal to us by letting COVID-19 run rampant. By studying the Bible, he discovered it is not silent when it comes to fighting an infectious disease. He answers questions such as: - How did ancient Israel fight the spread of another infectious disease-leprosy? - What does the Bible tell us about quarantining individuals who are sick or may be sick? - Why do some elected officials continue to display a lack of leadership amid the pandemic? The author also examines what the Bible says about using face coverings, what the world has done to fight other outbreaks of disease, and similarities between COVID-19 and other deadly viruses. Get simple, practical explanations from the Bible that will help you understand the spread of COVID-19-and how to protect yourself-with A Biblical Response to COVID-19.

Professors and research advisors have always endeavored to make the opportunity to gain new knowledge available to their students. However, new knowledge takes different forms. From a student perspective, it comes from reading textbooks and primary literature or attending classes and seminars. Professors share in these activities with their students, but they know that physically taking part in the acquisition of new knowledge through active research is where the true excitement begins. For many, if not all, faculty members research is the source of passion for chemistry, and sharing it with a rising generation of chemists often comprises a substantial part of the decision to pursue a career in the field of undergraduate education. These chapters and additional ones provide starting points for developing such a culture at the department level. In several cases the starting point is redesigning introductory or research methods courses to place a stronger emphasis on authentic research and its associated skills. In other cases the establishment of a thriving research group by one faculty member is the catalyst for initiating the departmental transformation. There are also several examples of how to set up an undergraduate research group in departments that place a heavy emphasis on research, and those that place less emphasis on research. Many of these offer roadmaps for developing interdisciplinary research groups or translating resource-intensive graduate-level research to an environment that is resource-restrictive. In still other cases the research has an experiential learning component. For many of the above examples the departmental/institutional role is not always obvious and may not be influential or important. This is a reminder that undergraduate research need not be "institutional" to be successful.

Newton on Matter and Activity shows persuasively that while the Principia remains within the first two stages of inquiry (mathematical and physical) into nature, Newton spent the next forty years of his life making a philosophical analysis of matter, force, and transmission of force. Close attention is paid to methodological issues, especially Newton's move beyond inductivism and toward a reproductive theoretical schema of interpretation required to treat of attraction, hardness, and impenetrability. --Cross Currents
