| planethood: The Crowded Universe Alan Boss, 2009-02-03 We are nearing a turning point in our quest for life in the universe -- we now have the capacity to detect Earth-like planets around other stars. But will we find any? In The Crowded Universe, renowned astronomer Alan Boss argues that based on what we already know about planetary systems, in the coming years we will find abundant Earths, including many that are indisputably alive. Life is not only possible elsewhere in the universe, Boss argues -- it is common. Boss describes how our ideas about planetary formation have changed radically in the past decade and brings readers up to date on discoveries of bizarre inhabitants of various solar systems, including our own. America must stay in this new space race, Boss contends, or risk being left out of one of the most profoundly important discoveries of all time: the first confirmed finding of extraterrestrial life. |

| planethood: The Oxford Handbook of Contemporary Philosophy of Language Una Stojnić, Ernie Lepore, 2025-01-02 The Oxford Handbook of Contemporary Philosophy of Language introduces readers to the main issues and theories in the philosophy of language as currently practised. Written by leading researchers and covering the central topics in the contemporary philosophical study of language, the twenty-seven chapters provide an overview of the state of the art, and a presentation of cutting-edge developments. Topics covered include: the nature of language; the nature and role of semantic and attitudinal content; the dynamics of communication and speech acts; meta-semantics and reference grounding; tense and modality; discourse dynamics and information structure; and the expressive, evaluative, subjective, and social aspects of language. Although some of the articles focus directly on technical issues following the recent approach of linguistically oriented philosophy of language, the majority of the contributions are primarily focused on foundational questions drawn from traditional philosophy of language. The volume offers a reconsideration of these foundational issues in a new light, while still bearing in mind the formal developments in recent literature, as well as a presentation of new foundational issues that have emerged as a result of these developments. |
| planethood: Reality and Morality Billy Dunaway, 2020-07-03 Reality and Morality develops and defends a framework for moral realism. It defends the idea that moral properties are metaphysically elite, or privileged parts of reality, and argues that realists can hold that this makes them highly eligible as the referents for our moral terms (an application of a thesis sometimes called reference magnetism). Billy Dunaway elaborates on these theses by introducing some natural claims about how we can know about morality, by having beliefs that are free from a kind of risk of error. This package of theses in metaphysics, meta-semantics, and epistemology is motivated with a view to explaining possible moral disagreements. Many writers have emphasized the scope of moral disagreement, and have given compelling examples of possible users of moral language who appear to be genuinely disagreeing, rather than talking past one another, with their use of moral language. What has gone unnoticed is that there are limits to these possible disagreements, and not all possible users of moral language are naturally interpreted as capable of genuine disagreement. The realist view developed in Reality and Morality can explain both the extent of, and the limits to, moral disagreement, and thereby has explanatory power that counts significantly in its favour. |
| planethood: Epistemic Cognition and Development David Moshman, 2014-12-05 Epistemic cognition, the philosophical core of metacognition, concerns people’s knowledge about the justification and truth of beliefs. Multiple literatures in psychology and education address aspects of epistemic cognition. In the absence of a coherent conceptual framework, however, these literatures mostly fail to communicate with each other and often connect only loosely to genuine epistemology. This complicates any effort to achieve a systematic theoretical understanding of epistemic cognition and its development. Deanna Kuhn writes in her foreword, Moshman is not the first to take on this challenge, but he fulfills it elegantly and, I think, the most comprehensively and astutely. After reviewing the basics of philosophical epistemology and cognitive psychology, Epistemic Cognition and Development provides a compelling account of developmental change across childhood and beyond in knowledge about knowledge, especially with regard to fundamental conceptions of objectivity, subjectivity, rationality, justification, and truth. This is followed by detailed consideration of domain-specific epistemologies of science, logic, morality, social convention, history, and identity, including associated forms of reasoning. The final section provides theoretical conclusions, educational and social applications, and suggestions for further research. |

| planethood: Meta-cognition Michael F. Shaughnessy, Marcel Veenman, Cynthia Kleyn Kennedy, 2008 Over the past two decades, the word 'metacognition' has become a regularly used part of our language and vocabulary in both psychology and education. Many research articles have been written about it, the conceptualisation of this construct has expanded, and conferences abound with investigations and empirical research into various facets of this domain. This book provides some of the most recent research by scholars from various parts of the world. It includes differing perspectives -- some empirical, some theory driven, and some application papers. The book focuses on metacognition and it's relevance to gifted and highly able students. Many of the papers focus directly and specifically on this; others are more tangential in nature. |

| planethood: Window to Ancient India : A Tryst with Ancient Science & Philosophy | Part II : Languages, Linguistic Systems and Indian Logic System vis-a-vis the Greeks Satish S. Joglekar, 2023-06-10 About the Book: Part II traces the evolution of languages from pre-Vedic Sanskrit to modern vernaculars via the Prakrit and the Apabravsha way. Coverage of Sanskrit, Prakrit, Apabravsha and Vernacular literature is illuminating - examples of Chitra Kavya, a genre of Sanskrit poetry, reflect the ingenuity of Sanskrit poets. The evolution of modern scripts from Brahami and families of Indian languages are well exemplified. It explains, why Panini's grammar is sufficiently detailed to qualify as the earliest known computing language. His grammar is one of the earliest context-sensitive grammars with a hint of transformational grammar. Part II covers topics like the Philosophy of Language and Sphota Theory. The latter anticipated psycholinguistics ahead of its time. Indian languages are phonetic and the only languages that are word order independent. Thanks to Panini's Karaka (Case) theory and his categorization of phones depending on various movements of mouth and tongue. No wonder Chomsky has acknowledged Panini as his Guru. Lastly, it compares the Indian and Greek Logic systems through examples, bringing out differences in their approach. For example, Indians were not restricted by the principle of 'Excluded Middle' leading very on to the recognition of multi-valued logic. About the Author: Satish Joglekar is an engineer from IIT Bombay, with a Master’s in computer science. He has worked with several software companies for more than 30 years which included a long stint at Bell Laboratories, USA. Satish is trained in Hindustani classical music and has intense interest in history, non-fiction literature, and travel. |

| planethood: Words and Distinctions for the Common Good Gabriel Abend, 2023-07-25 In this book, Gabriel Abend argues that social scientists need to focus more on the words and distinctions that their empirical claims depend on. He suggests two central questions researchers need to consider. First, how should word w be used in the social science community? Which is to say, how should word w be defined, should it be used at all, and if so, on what grounds? Second, should distinction d be accepted in the social science community? For example, when a social scientist proposes a distinction between childhood, adolescence, adulthood and old age, should they be accepted and on what grounds? Which distinctions and classifications are good for the social science community? Throughout the chapters, Abend carefully investigates these core issues and related questions, arguing along the way that there is not a definitive answer. Instead, the book invites the social science community to work together to collectively address these consequential concerns-- |
| planethood: The Routledge Handbook of Propositions Chris Tillman, Adam Russell Murray, 2022-09-30 Propositions are routinely invoked by philosophers, linguists, logicians, and other theorists engaged in the study of meaning, communication, and the mind. To investigate the nature of propositions is to investigate the very nature of our connection to each other, and to the world around us. As one of the only volumes of its kind, The Routledge Handbook of Propositions provides a comprehensive overview of the philosophy of propositions, from both historical and contemporary perspectives. Comprising 33 original chapters by an international team of scholars, the volume addresses both traditional and emerging questions concerning the nature of propositions, and our capacity to engage with them in thought and in communication. The chapters are clearly organized into the following three sections: I. Foundational Issues in the Theory of Propositions II. Historical Theories of Propositions III. Contemporary Theories of Propositions Essential reading for philosophers of language and mind, and for those working in neighboring areas, The Routledge Handbook of Propositions is suitable for upper-level undergraduate study, as well as graduate and professional research. |

| planethood: Interactive World, Interactive God Carol Rausch Albright, John R. Albright, Mladen Turk, 2017-11-06 Since the dawn of science, ideas about the relation between science and religion have always depended on what else is going on in a society. During the twentieth century, daily life changed dramatically. Technology revolutionized transportation, agriculture, communications, and housework. People came to rely on scientific predictability in their technology. Many wondered whether God's supposed actions were consistent with scientific knowledge. The twenty-first century is bringing new scientific research capabilities. They are revealing that scientific results are not totally predictable after all. Certain types of interaction lead to outcomes that are unpredictable, in principle. These in turn may lead to a whole new range of potential interactions. They do not rule out the reality of a dynamic God who can act in the world without breaking the known principles of science. God may in fact work with the way things really are. Human experience of God may accurately reflect this reality. Interactive World, Interactive God illustrates such new understandings in religion and science by describing recent developments in a wide range of sciences, and providing theological commentary. The book is written for intelligent readers who may not be specialized in science but who are looking for ways to understand divine action in today's world. |

| planethood: The Pluto Files: The Rise and Fall of America's Favorite Planet Neil deGrasse Tyson, 2010-07-12 The New York Times bestseller: You gotta read this. It is the most exciting book about Pluto you will ever read in your life. —Jon Stewart When the Rose Center for Earth and Space at the American Museum of Natural History reclassified Pluto as an icy comet, the New York Times proclaimed on page one, Pluto Not a Planet? Only in New York. Immediately, the public, professionals, and press were choosing sides over Pluto's planethood. Pluto is entrenched in our cultural and emotional view of the cosmos, and Neil deGrasse Tyson, award-winning author and director of the Rose Center, is on a quest to discover why. He stood at the heart of the controversy over Pluto's demotion, and consequently Plutophiles have freely shared their opinions with him, including endless hate mail from third-graders. With his inimitable wit, Tyson delivers a minihistory of planets, describes the oversized characters of the people who study them, and recounts how America's favorite planet was ousted from the cosmic hub. |
| planethood: How Long is Now? New Scientist, 2016-11-22 Big or small, there's an answer to every question, and sometimes there are even a few! How long is now? The short answer is somewhere between 2 and 3 seconds. The long answer involves an incredible journey through neuroscience, our subconscious and the time-bending power of meditation. Living in the present may never feel the same. Ready for some more? Okay. Why isn't Pluto a planet? Why are dogs' noses wet? Why do hens cluck more loudly after laying an egg? What happens when one black hole swallows another? Do our fingerprints change as we get older? How young can you die of old age? And what is at the very edge of the universe? Life is full of mind-bending questions, and, as books like What If? and Why Don't Penguins' Feet Freeze? have shown, the route to find each answer can take us on the weirdest and most wonderful journeys. How Long is Now? is a fascinating new collection of questions you never thought to ask, along with answers that will change the way you see everything. |

| planethood: The Case for Pluto Alan Boyle, 2009-10-22 In support of Pluto-the cutest and most unfairly treated planet Pity poor Pluto: It's a planet that was discovered because of a mistake, a planet that turned out not to be a planet at all, thanks to a still-disputed decision made in 2006. And yet, Pluto is the planet best-loved by Americans, especially children, one that may have contained the building blocks of life billions of years ago and may well serve as life's last redoubt billions of years from now. In The Case for Pluto, award-winning science writer Alan Boyle traces the tiny planet's ups and downs, its strange appeal, the reasons behind its demotion, and the reasons why it should be set back in the planetary pantheon. Tells the compelling story of Pluto's discovery and how it became a cultural icon Makes the case for Pluto as planet, countering the books that argue against it Comes in a small, friendly package — just like Pluto — and features a handsome design, making it a great gift The Case for Pluto is the must-read tale of a cosmic underdog that has captured the hearts of millions: an endearing little planet that is changing the way we see the universe beyond our backyard. Alan Boyle is MSNBC.com’s science editor and the award-winning blogger behind Cosmic Log. He’s been a talking head on NBC’s The Today Show and the MSNBC cable channel, holding forth on scientific subjects ranging from the chances of an asteroid Armageddon to the 3-D wizardry behind the “Harry Potter” movies. But he writes better than he talks. |
| planethood: Guide to the Universe: Asteroids, Comets, and Dwarf Planets Andrew S. Rivkin, 2009-10-15 Geared toward students, this guide provides an overview of the small bodies that orbit the sun. This volume in the Greenwood Guides to the Universe series covers asteroids, comets, and dwarf planets—those small bodies that revolve the Sun—and provides readers with the most up-to-date understanding of the current state of scientific knowledge about them. Scientifically sound, but written with the student in mind, Asteroids, Comets, and Dwarf Planets is an excellent first step for researching the exciting scientific discoveries of the smallest celestial bodies in the solar system. The book will introduce students to all of the areas of research surrounding the subject, answering many intriguing questions. It defines a dwarf planet and explains why Pluto is one. It looks at how such small bodies form, what they are made of, and what kind of atmospheres might they have. And it asks—and answers—whether asteroids, comets, and dwarf planets present a hazard to the Earth or to spacecraft. |

The cutting-edge collection of articles on these topics is an excellent source of the latest information on this fascinating subject. |
| planethood: Weird Worlds David A. J. Seargent, 2013-04-18 “Weird Worlds” is the third book in David Seargent’s “Weird” series. This book assumes a basic level of astronomical understanding and concentrates on the “odd and interesting” aspects of planetary bodies, including asteroids and moons. From our viewpoint here on Earth, this work features the most unusual features of these worlds and the ways in which they appear “weird” to us. Within our own Solar System, odd facts such as the apparent reversal of the Sun in the skies of Mercury, CO2-driven fountains of dust on Mars, possible liquid water (and perhaps primitive life!) deep within the dwarf planet Ceres, and a variety of odd facts about the planetary moons are all discussed. A special chapter is devoted to Saturn’s giant moon Titan, and its methane-based weather system and “hydrological” cycle. This chapter also includes recent speculation on the possibility of methane-based organisms and the form that these might take, if they really do exist. Beyond our Solar System, the book looks at the range of worlds discovered and hypothesized. In “Weird Worlds,” the author discusses planets where temperatures are so high that it rains molten iron, and others so cold that liquid methane floods across plains of ice! Worlds are described where the lightest element acts like a metal and where winds blow at thousands of miles per hour – as well as possible planets whose orbits are essentially parabolic. In keeping with previous titles in David Seargent’s “Weird” series, “Weird Worlds” contains several projects that astronomers of all levels can undertake. |

| planethood: The Pluto Files: The Rise and Fall of America's Favorite Planet Neil deGrasse Tyson, 2009-12-07 The New York Times best-selling author chronicles America's irrational love affair with Pluto, man's best celestial friend. In August 2006, the International Astronomical Union voted Pluto out of planethood. Far from the sun, tiny, and eccentric in orbit, it's a wonder Pluto has any fans. Yet during the mounting debate over Pluto's status, Americans rallied behind the extraterrestrial underdog. The year of Pluto's discovery, Disney created an irresistible pup by the same name, and, as one NASA scientist put it, Pluto was discovered by an American for America. Pluto is entrenched in our cultural, patriotic view of the cosmos, and Neil deGrasse Tyson is on a quest to discover why. Only Tyson can tell this story: he was involved in the first exhibits to demote Pluto, and, consequently, Pluto lovers have freely shared their opinions with him, including endless hate mail from third graders. In his typically witty way, Tyson explores the history of planet classification and America's obsession with the planet that's recently been judged a dwarf. |
| planethood: Lying Eliot Michaelson, Andreas Stokke, 2018-10-04 Philosophers have been thinking about lying for several thousand years, yet this topic has only recently become a central area of academic interest for philosophers of language, epistemologists, ethicists, and political philosophers. Lying: Language, Knowledge, Ethics, Politics provides the first dedicated collection of philosophical essays on the emerging topic of lying. Adopting an inter-subdisciplinary approach, this volume breaks new methodological ground in exploring the ways that a better understanding of language can inform the study of knowledge, ethics, or politics - and vice-versa. How can we lie when it is unclear what exactly we believe, or when we have contradictory beliefs? Can corporations lie, and if so how? Is lying always wrong, or always at least prima facie wrong? What can one learn from a liar? Can we lie to mindless machines? These engaging questions and many more are explored at length in this accessible reference text. |
| planethood: Benjamin Ferencz, Nuremberg Prosecutor and Peace Advocate Tom Hofmann, 2013-11-21 At the conclusion of World War II, war crimes tribunals were carried out at Nuremberg, Germany. Justice was meted out for major war criminals, and Benjamin Ferencz was chief prosecutor for what the Associated Press said was the largest murder trial in history. This biography of the last living Nuremberg prosecutor traces his life from early childhood growing up as an immigrant in Hell's Kitchen in New York City, to Harvard Law School, to the U.S. Army and Patton's Judge Advocate War Crimes Investigation Section, to the Nuremberg Tribunals and beyond. His life has been spent working toward the goal of world peace through law, not war, including the successful formation of the International Criminal Court, in which Ferencz played a key role. |

| planethood: Forgiveness and Atonement Jonathan Rutledge, 2022-03-31 This book analyzes the relationship between forgiveness, atonement, and reconciliation from a Christian theological perspective. Drawing on both theological and philosophical literature, it addresses the problem of whether atonement is required for forgiveness and considers important related concepts such as sin and justice. The author develops a sacrificial model of atonement that connects an understanding of Christian forgiveness with the biblical narrative of Christ’s sacrifice and makes reconciliation between God and humanity possible. Offering a fresh and coherent argument, the book will be relevant to scholars of Christian theology, biblical studies, and the philosophy of religion. |
| planethood: Habitable Exoplanets for Extra-Terrestrials C.R. Kitchin, 2024-12-19 This book explores the questions of What, Why, When, How and Where we might find Extra-Terrestrials (a.k.a. Aliens) and their habitats throughout the Universe – and Who might they be? Starting from ourselves and the Earth and eventually speculating about life-forms that might span multiple Universes, it provides an accessible introduction to extra-terrestrial life, the search for extra-terrestrial intelligence and exoplanets. It will enable readers to appreciate, follow and sometimes answer questions on life and planets outside Earth. It details these exciting topics by pondering what comprises an alien life form and what suitable habitats might exist for them inside and out of our solar system. The book also looks ahead to the future and the realities of finding alien life and the possibilities of mankind leaving Earth and living on another planet. This guide is accessible to those without a formal scientific or mathematical background. It will also be of interest to students of astrobiology, astronomy, astrophysics, planets throughout the Universe, the origin and evolution of life-forms beyond the Earth and (perhaps) of the ultimate limits attainable by life in the Universe, who are looking to learn more about those same topics, but which are outside their own specialisms. Key Features: Combines the exciting topics of extra-terrestrial life, the search for life outside Earth and exoplanets into one accessible guide Contains no complex mathematical formulae or content Authored by a professional educator and a professional and amateur astronomer, with a life-long interest in getting everyone and anyone as fascinated by astronomy and its related subjects as he himself has been, since discovering the subject in early secondary school |
| planethood: Is Pluto a Planet? David A. Weintraub, 2008-12-14 A Note from the Author: On August 24, 2006, at the 26th General Assembly of the International Astronomical Union (IAU) in Prague, by a majority vote of only the 424 members present, the IAU (an organization of over 10,000 members) passed a resolution defining planet in such a way as to exclude Pluto and established a new class of objects in the solar system to be called dwarf planets, which was deliberately designed to include Pluto. With the discovery of Eris (2003 UB313)—an outer solar system object thought to be both slightly larger than Pluto and twice as far from the Sun—astronomers have again been thrown into an age-old debate about what is and what is not a planet. One of many sizeable hunks of rock and ice in the Kuiper Belt, Eris has resisted easy classification and inspired much controversy over the definition of planethood. But, Pluto itself has been subject to controversy since its discovery in 1930, and questions over its status linger. Is it a planet? What exactly is a planet? Is Pluto a Planet? tells the story of how the meaning of the word planet has changed from antiquity to the present day, as new objects in our solar system have been discovered. In lively, thoroughly accessible prose, David Weintraub provides the historical, philosophical, and astronomical background that allows us to decide for ourselves whether Pluto is indeed a planet. The number of possible planets has ranged widely over the centuries, from five to seventeen. This book makes sense of it all—from the ancient Greeks' observation that some stars wander while others don't; to Copernicus, who made Earth a planet but rejected the Sun and the Moon; to the discoveries of comets, Uranus, Ceres, the asteroid belt, Neptune, Pluto, centaurs, the Kuiper Belt and Eris, and extrasolar planets. Weaving the history of our thinking about planets and cosmology into a single, remarkable story, Is Pluto a Planet? is for all those who seek a fuller understanding of the science surrounding both Pluto and the provocative recent discoveries in our outer solar system. |

According to this ontology, the relata of the belief-relation are an agent and a special sort of object-dependent sense (a thought-content), the latter being an abstract property encoding various syntactic and semantic constraints on sentences of a language of thought. |
