This volume argues that history reveals our routine failure to even conceive of well-confirmed alternatives to our scientific theories, and similar alternatives to our own theories likely remain unconceived. It shows why defences of scientific realism cannot evade the problem and proposes an alternative image of the scientific enterprise.
Roughly, instrumentalism is the view that science is primarily, and should primarily be, an instrument for furthering our practical ends. It has fallen out of favour because historically influential variants of the view, such as logical positivism, suffered from serious defects. In this book, however, Darrell P. Rowbottom develops a new form of instrumentalism, which is more sophisticated and resilient than its predecessors. This position—‘cognitive instrumentalism’—involves three core theses. First, science makes theoretical progress primarily when it furnishes us with more predictive power or understanding concerning observable things. Second, scientific discourse concerning unobservable things should only be taken literally in so far as it involves observable properties or analogies with observable things. Third, scientific claims about unobservable things are probably neither approximately true nor liable to change in such a way as to increase in truthlikeness. There are examples from science throughout the book, and Rowbottom demonstrates at length how cognitive instrumentalism fits with the development of late nineteenth- and early twentieth-century chemistry and physics, and especially atomic theory. Drawing upon this history, Rowbottom also argues that there is a kind of understanding, empirical understanding, which we can achieve without having true, or even approximately true, representations of unobservable things. In closing the book, he sets forth his view on how the distinction between the observable and unobservable may be drawn, and compares cognitive instrumentalism with key contemporary alternatives such as structural realism, constructive empiricism, and semirealism. Overall, this book offers a strong defence of instrumentalism that will be of interest to scholars and students working on the debate about realism in philosophy of science.
The authors document how four forces--exponential technologies, the DIY innovator, the Technophilanthropist, and the Rising Billion--are conspiring to solve our biggest problems. "Abundance" establishes hard targets for change and lays out a strategic roadmap for governments, industry and entrepreneurs, giving us plenty of reason for optimism.
The incredible achievements of modern scientific theories lead most of us to embrace scientific realism: the view that our best theories offer us at least roughly accurate descriptions of otherwise inaccessible parts of the world like genes, atoms, and the big bang. In Exceeding Our Grasp, Stanford argues that careful attention to the history of scientific investigation invites a challenge to this view that is not well represented in contemporary debates about the nature of the scientific enterprise. The historical record of scientific inquiry, Stanford suggests, is characterized by what he calls the problem of unconceived alternatives. Past scientists have routinely failed even to conceive of alternatives to their own theories and lines of theoretical investigation, alternatives that were both well-confirmed by the evidence available at the time and sufficiently serious as to be ultimately accepted by later scientific communities. Stanford supports this claim with a detailed investigation of the mid-to-late 19th century theories of inheritance and generation proposed in turn by Charles Darwin, Francis Galton, and August Weismann. He goes on to argue that this historical pattern strongly suggests that there are equally well-confirmed and scientifically serious alternatives to our own best theories that remain currently unconceived. Moreover, this challenge is more serious than those rooted in either the so-called pessimistic induction or the underdetermination of theories by evidence, in part because existing realist responses to these latter challenges offer no relief from the problem of unconceived alternatives itself. Stanford concludes by investigating what positive account of the spectacularly successful edifice of modern theoretical science remains open to us if we accept that our best scientific theories are powerful conceptual tools for accomplishing our practical goals, but abandon the view that the descriptions of the world around us that they offer are therefore even probably or approximately true.
A provocative and inspiring look at the future of humanity and science from world-renowned scientist and bestselling author Martin Rees Humanity has reached a critical moment. Our world is unsettled and rapidly changing, and we face existential risks over the next century. Various outcomes—good and bad—are possible. Yet our approach to the future is characterized by short-term thinking, polarizing debates, alarmist rhetoric, and pessimism. In this short, exhilarating book, renowned scientist and bestselling author Martin Rees argues that humanity’s prospects depend on our taking a very different approach to planning for tomorrow. The future of humanity is bound to the future of science and hinges on how successfully we harness technological advances to address our challenges. If we are to use science to solve our problems while avoiding its dystopian risks, we must think rationally, globally, collectively, and optimistically about the long term. Advances in biotechnology, cybertechnology, robotics, and artificial intelligence—if pursued and applied wisely—could empower us to boost the developing and developed world and overcome the threats humanity faces on Earth, from climate change to nuclear war. At the same time, further advances in space science will allow humans to explore the solar system and beyond with robots and AI. But there is no “Plan B” for Earth—no viable alternative within reach if we do not care for our home planet. Rich with fascinating insights into cutting-edge science and technology, this accessible book will captivate anyone who wants to understand the critical issues that will define the future of humanity on Earth and beyond.
This exploration of the scientific limits of knowledge challenges our deep-seated beliefs about our universe, our rationality, and ourselves. “A must-read for anyone studying information science.” —Publishers Weekly, starred review Many books explain what is known about the universe. This book investigates what cannot be known. Rather than exploring the amazing facts that science, mathematics, and reason have revealed to us, this work studies what science, mathematics, and reason tell us cannot be revealed. In The Outer Limits of Reason, Noson Yanofsky considers what cannot be predicted, described, or known, and what will never be understood. He discusses the limitations of computers, physics, logic, and our own intuitions about the world—including our ideas about space, time, and motion, and the complex relationship between the knower and the known. Yanofsky describes simple tasks that would take computers trillions of centuries to complete and other problems that computers can never solve: • perfectly formed English sentences that make no sense • different levels of infinity • the bizarre world of the quantum • the relevance of relativity theory • the causes of chaos theory • math problems that cannot be solved by normal means • statements that are true but cannot be proven Moving from the concrete to the abstract, from problems of everyday language to straightforward philosophical questions to the formalities of physics and mathematics, Yanofsky demonstrates a myriad of unsolvable problems and paradoxes. Exploring the various limitations of our knowledge, he shows that many of these limitations have a similar pattern and that by investigating these patterns, we can better understand the structure and limitations of reason itself. Yanofsky even attempts to look beyond the borders of reason to see what, if anything, is out there.
Andrew Piper grew up liking books and loving computers. While occasionally burying his nose in books, he was going to computer camp, programming his Radio Shack TRS-80, and playing Pong. His eventual love of reading made him a historian of the book and a connoisseur of print, but as a card-carrying member of the first digital generation—and the father of two digital natives—he understands that we live in electronic times. Book Was There is Piper’s surprising and always entertaining essay on reading in an e-reader world. Much ink has been spilled lamenting or championing the decline of printed books, but Piper shows that the rich history of reading itself offers unexpected clues to what lies in store for books, print or digital. From medieval manuscript books to today’s playable media and interactive urban fictions, Piper explores the manifold ways that physical media have shaped how we read, while also observing his own children as they face the struggles and triumphs of learning to read. In doing so, he uncovers the intimate connections we develop with our reading materials—how we hold them, look at them, share them, play with them, and even where we read them—and shows how reading is interwoven with our experiences in life. Piper reveals that reading’s many identities, past and present, on page and on screen, are the key to helping us understand the kind of reading we care about and how new technologies will—and will not—change old habits. Contending that our experience of reading belies naive generalizations about the future of books, Book Was There is an elegantly argued and thoroughly up-to-date tribute to the endurance of books in our ever-evolving digital world.
Satisfy your intrinsic desire to rise above the norm. Isn’t it true that we long to see the extraordinary, experience the extraordinary, do the extraordinary? Yet, so often we settle for mediocrity when greatness is within our grasp. Why are we drawn to stories of heroic triumph over seemingly impossible circumstances? In our fascination with adventure movies, superheroes, and tales of incredible human feats, do we reveal an inherent desire for something larger and greater in life? Maybe what we think is a need to escape or be entertained is actually a God inspired longing…for the extraordinary. Best-selling author John Bevere reveals how all of us were “meant for more,” extraordinarily created and intended for a life that is anything but ordinary. Here is the roadmap for your journey of transformation. You are marked for a life that far surpasses the usual definitions of success or fulfillment. Isn’t it time to pursue your extraordinary life?
“Human beings have been smart enough to turn nature to their ends, generate vast wealth for themselves, and double their average life span. But are they smart enough to solve the problems of the 21st century?” -- Thomas Homer-Dixon In The Ingenuity Gap, Thomas Homer-Dixon, "global guru" (the Toronto Star), asks: is our world becoming too complex, too fast-paced to manage? The challenges facing us converge, intertwine, and remain largely beyond our ken. Most of suspect the "experts don't really know what's going on; that as a species we've released forces that are neither managed nor manageable. We are fast approaching a time when we may no longer be able to control a world that increasingly exceeds our grasp. This is "the ingenuity gap" -- the term coined by Thomas Homer-Dixon -- the critical gap between our need for practical, innovative ideas to solve complex problems and our actual supply of those ideas. Through gripping narrative stories and incidents that exemplify his arguments, he takes us on a world tour that begins with a heartstopping description of the tragic crash of United Airlines Flight 232 from Denver to Chicago and includes Las Vegas in its desert, a wilderness beach in British Columbia, and his solitary search for a little girl in Patna, India. He shows how, in our complex world, while poor countries are particularly vulnerable to ingenuity gaps, our own rich countries are not immune, and we are caught between a requirement for ingenuity and an increasingly uncertain supply. When the gap widens, political disintegration and violent upheaval can result, reaching into our own economies and daily lives in subtle ways. In compelling, lucid, prose, he makes real the problems we face and suggests how we might overcome them.
Christians know that God loves them, but can easily feel that he is perpetually disappointed and frustrated, maybe even close to giving up on them. As a result, they focus a lot—and rightly so—on what Jesus has done to appease God’s wrath for sin. But how does Jesus Christ actually feel about his people amid all their sins and failures? This book draws us to Matthew 11, where Jesus describes himself as “gentle and lowly in heart,” longing for his people to find rest in him. The gospel flows from God’s deepest heart for his people, a heart of tender love for the sinful and suffering. These chapters take readers into the depths of Christ’s very heart for sinners, diving deep into Bible passages that speak of who Christ is and encouraging readers with the affections of Christ for his people. His longing heart for sinners comforts and sustains readers in their up-and-down lives.
