The laws of physics provide clear-cut principles defining what is possible - and not possible - in the physical world. This book examines and critiques many widely held pseudoscientific beliefs in light of these laws. Rather than treating supernatural claims on a case-by-case basis, Milton Rothman uses the general principles supplied by physics to show why they are, in fact, impossible. Rothman divides the laws of physics into two classes: laws of permission and laws of denial. Laws of permission, such as Newton's laws of motion, generally do not allow precise predictions except in the simplest cases. Laws of denial, such as conservation of energy, permit very accurate conclusions about what cannot possibly occur. He uses these concepts to examine and critique the possible existence of various paranormal phenomena, such as UFOs, telepathy, perpetual motion machines, poltergeists, etc. He also discusses a number of concepts traditional to science fiction: anti-gravity, faster-than-light travel, time travel, etc., which are shown to be impossible when subject to rigorous examination. Written in a technically accurate yet entertaining style, this book will appeal to the non-specialist yet still present concepts of interest to both professional scientists and philosophers of science.

What would happen if you faced your doubts, set aside your preconceptions, and decided to follow the path of truth wherever it might lead? Most people, whether believers or atheists, doggedly defend what they have always believed. Many see this as an expression of faith. Yet, there is something almost inexpressibly sad about the plight of people living out their lives in reliance upon beliefs they dare not question. Perhaps that is why many of us come to a point at which we feel compelled to pursue the truth, no matter what the implications. But even if we found the courage to embark upon such a journey, could we really find a path through the scientific, philosophical, experiential, and theological thickets that surround the great questions of life? And if we did, would we know the truth and be set free? Would we be forced to face a long-feared despair? Or would we find ourselves still staring impotently at an enigmatic universe? This is a book unlike any other. It addresses these questions with unflinching honesty, drawing evidence from a diversity of scientific fields and subjecting the competing arguments to rigorous skeptical analysis.

Mass ideology is unique to modern society and rooted in early modern philosophy. Traditionally, knowledge had been viewed as resting on metaphysics. Rejecting metaphysical truth evoked questions about the source of -truth.- For nineteenth-century ideologists, -truth- comes either from dominating classes in a progressively determined history or from a post-Copernican freedom of the superior man to create it. In From Physics to Politics Robert C. Trundle, Jr. uncovers the relation of modern philosophy to political ideology. And in rooting truth in human nature and Nature by modal reasoning, he resolves the problem of politicized truth. Our concepts of scientific truth, logic, and necessity are essentially connected. Modern philosophy restricts our understanding of necessity to the political dreams and aspirations of Enlightenment intellectuals. As a result, these intellectuals refuse to acknowledge as factual or meaningful whatever is not intelligible within the practical goals of establishing science as a system of enlightened ideas. The effect of these ideas is that in our time metaphysical principles, speculative truths, our understanding of science, and the nature of logic have become subordinated to ideological dreams. Fascism, Nazism, Marxism, political correctness, and moral relativism are not historical aberrations but essential consequences. Trundle's work is groundbreaking and daring, and his underlying thesis demonstrates why scientific truth demands a modal defense. The defense not only integrates science, ethics, and politics, but shows how -truth- may be ascribed to moral and scientific principles in contrast to a modern philosophical tradition. Since this tradition is the origin of political ideology, it has led to an irrational politicization of truth. The book will appeal particularly to those interested in political history, histories of philosophy, the philosophy of sciences, and ethics.

Wittgenstein's Metaphysics offers a radical new interpretation of the fundamental ideas of Ludwig Wittgenstein. It takes issue with the conventional view that after 1930 Wittgenstein rejected the philosophy of the Tractatus and developed a wholly new conception of philosophy. By tracing the evolution of Wittgenstein's ideas, Cook shows that they are neither as original nor as difficult as is often supposed. Wittgenstein was essentially an empiricist, and the difference between his early views (as set forth in the Tractatus) and the later views (as expounded in the Philosophical Investigations) lies chiefly in the fact that after 1930 he replaced his early version of reductionism with a subtler version. So he ended where he began, as an empiricist armed with a theory of meaning. This iconoclastic interpretation is sure to influence all future study of Wittgenstein and will provoke a reassessment of the nature of his contribution to philosophy.

An all-encompassing guide to skeptical thinking from podcast host and academic neurologist at Yale University School of Medicine Steven Novella and his SGU co-hosts, which Richard Wiseman calls "the perfect primer for anyone who wants to separate fact from fiction." It is intimidating to realize that we live in a world overflowing with misinformation, bias, myths, deception, and flawed knowledge. There really are no ultimate authority figures-no one has the secret, and there is no place to look up the definitive answers to our questions (not even Google). Luckily, The Skeptic's Guide to the Universe is your map through this maze of modern life. Here Dr. Steven Novella-along with Bob Novella, Cara Santa Maria, Jay Novella, and Evan Bernstein-will explain the tenets of skeptical thinking and debunk some of the biggest scientific myths, fallacies, and conspiracy theories-from anti-vaccines to homeopathy, UFO sightings to N- rays. You'll learn the difference between science and pseudoscience, essential critical thinking skills, ways to discuss conspiracy theories with that crazy co- worker of yours, and how to combat sloppy reasoning, bad arguments, and superstitious thinking. So are you ready to join them on an epic scientific quest, one that has taken us from huddling in dark caves to setting foot on the moon? (Yes, we really did that.) DON'T PANIC! With The Skeptic's Guide to the Universe, we can do this together. "Thorough, informative, and enlightening, The Skeptic's Guide to the Universe inoculates you against the frailties and shortcomings of human cognition. If this book does not become required reading for us all, we may well see modern civilization unravel before our eyes." -- Neil deGrasse Tyson "In this age of real and fake information, your ability to reason, to think in scientifically skeptical fashion, is the most important skill you can have. Read The Skeptics' Guide Universe; get better at reasoning. And if this claim about the importance of reason is wrong, The Skeptics' Guide will help you figure that out, too." -- Bill Nye

The raging COVID-19 pandemic has shaken our trust in science. This volume reviews the evolution of misconduct and fraud in science, the many steps taken to alleviate the problem, and the likelihood that it will continue, given our profit-driven healthcare system. Contents are set in a clinical context, wherein misconduct and fraud affect rational prescribing, a process that depends on balancing the risk–benefit ratio of treatments, whether pharmacologic or psychotherapeutic. The clinical consequences can be significant, in that the efficacy of treatments can be vastly overplayed, adverse effects minimized, and costs to the healthcare system increased if corrective measures are not taken. Key Features • Discusses the various aspects of cheating in publications: spin, protocol changes; failure to publish negative studies, including current data on the publishing industry and its issues, like the menace of predatory journals, poor peer review, coupled with lack of early education in ethics, and its significant impact on rational prescribing. • Assesses the impact of misconduct and fraud on clinicians and healthcare professionals as they attempt to balance the risk–benefit ratio which is supported by multiple contemporary studies. • Presents shocking data on bribes to physicians, journal editors and other key opinion leaders, exposing the ultimate root of the problem which lies in the economics of the healthcare system, badly in need of repair.

From the bestselling authors and hosts of "The Skeptics' Guide to the Universe," a high-tech roadmap of the future in their beloved voice, cracking open the follies of futurists past and how technology will profoundly change our world, redefining what it means to be human. Our predictions of the future are a wild fantasy, inextricably linked to our present hopes and fears, biases and ignorance. Whether they be the outlandish leaps predicted in the 1920s, like multi-purpose utility belts with climate control capabilities and planes the size of luxury cruise ships, or the forecasts of the ‘60s, which didn’t anticipate the sexual revolution or women’s liberation, the path to the present is littered with failed predictions and incorrect estimations. The best we can do is try to absorb the lessons from futurism's checkered past, perhaps learning to do a little better. In THE SKEPTICS' GUIDE TO THE FUTURE, Steven Novella and his co-authors build upon the work of futurists of the past by examining what they got right, what they got wrong, and how they came to those conclusions. By exploring the pitfalls of each era, they give their own speculations about the distant future, transformed by unbelievable technology ranging from genetic manipulation to artificial intelligence and quantum computing. Applying their trademark skepticism, they carefully extrapolate upon each scientific development, leaving no stone unturned as they lay out a vision for the future.

This book examines central themes in the thought of Rabbi Hasdai Crescas (c. 1340-1410/11), the great Catalan Jewish philosopher who contributed to the revolution of modern science and profoundly influenced Spinoza. Part I treats of Crescas' radical critique of the Aristotelian concepts of space, time, and the vacuum, and analyzes his vision of an infinite universe; it discusses his criticisms of Maimonides' proofs of God, and expounds his own proof; and it concludes with a discussion of his concept of God as infinite Love. Part II contains three essays on Crescas' strictly deterministic theory of human choice.
