This Very Short Introduction looks at the Devil in the history of ideas and in the lives of real people. Darren Oldridge shows us that the Devil is an important figure in western history--a richly complex and contradictory one. Oldridge focuses on three main themes: the idea of the Devil being integral to western thought from the early Middle Ages to the beginnings of modernity; the belief that the Devil represents the mirror image of goodness; and the multiplicity and instability of ideas about the Devil. Oldridge concludes by exploring "demonological" ways of thinking in our own time, including allegations of "satanic ritual abuse."

    Indeed, from childhood most of us develop some mental image of a witch--usually an old woman, mysterious and malignant. But why do witches still feature so heavily in our cultures and consciousness? From Halloween superstitions to literary references such as Faust and, of course, Harry Potter, witches seem ever-present in our lives. In this Very Short Introduction, Malcolm Gaskill takes a long historical perspective, from the ancient world to contemporary paganism. This is a book about the strangeness of the past, and about contrasts and change; but it's also about affinity and continuity. He reveals that witchcraft is multi-faceted, that it has always meant different things to different people, and that in every age it has raised questions about the distinction between fantasy and reality, faith and proof. Delving into court records, telling anecdotes, and challenging myths, Gaskill re-examines received wisdom, especially concerning the European witch-hunts of the sixteenth and seventeenth centuries. He also explores the modern memory and reinvention of witchcraft--as history, religion, fiction, and metaphor.

    According to these sources, they were a learned caste who officiated in religious ceremonies, taught the ancient wisdoms, and were revered as philosophers. But few figures flit so elusively through history, and the Druids remain enigmatic and puzzling to this day. In this Very Short Introduction, one of the leading authorities on British archaeology, Barry Cunliffe, takes the reader on a fast-paced look at the ever-fascinating story of the Druids, as seen in the context of the times and places in which they practiced. Sifting through the evidence, Cunliffe offers an expert's best guess as to what can be said and what can't be said about the Druids, discussing the origins of the Druids and the evidence for their beliefs and practices, why the nature of the druid caste changed quite dramatically over time, and how successive generations have seen them in very different ways.

    The book describes dramatic breakthroughs in our knowledge of how sleep occurs, what it does, and what happens to our health if we do not have enough. The authors consider the impact of modern society, examining the relationship between sleep and our 24/7 culture.

    Not only are galaxies fascinatingastronomical structures in themselves, but their study has revealed much of what we know today about the cosmos, providing a window on the Big Bang and the origins of the Universe. Gribben looks at our own Milky Way Galaxy in detail, from the different kinds of stars that are born within it, tothe origins of its magnificent spiral structure. Perhaps most interesting, Gribben describes the many exciting discoveries have been made about our own galaxy and about those beyond: how a supermassive black hole lurks at the center of every galaxy, how enormous forces are released when galaxiescollide, how distant galaxies provide a window on the early Universe, and how the formation of young galaxies shed needed light on the mysteries of Cold Dark Matter.About the Series: Combining authority with wit, accessibility, and style, Very Short Introductions offer an introduction to some of life's most interesting topics.

    The relics of their power, in traditions and behavior, in architecture and the arts, are still all around us. This engaging Very Short Introduction shows how ideas of aristocracy originated in ancient times, were transformed in the middle ages, and have only fallen apart over the last two centuries, following the outbreak of the American and French Revolutions. William Doyle, an authority on eighteen-century European history, here strips away the myths in which aristocracies have always sought to shroud themselves, but he also astutely delineates the true sources of their enduring power. Their outlook and behavior affected the rest of society in innumerable and sometimes surprising ways, but perhaps most surprising was the way in which the centuries-old aristocratic hegemony crumbled away. In this Very Short Introduction William Doyle considers why this happened and what is left today.

    Indeed, without religion, our lives are left without meaning and are likely to degenerate into moral chaos. In this Very Short Introduction, philosopher Stephen Law explains why these claims are false and why humanism--though a rejection of religion--nevertheless provides both a moral basis and a meaning for our lives. Indeed, Law shows that humanism is a quite positive alternative to religion. The humanist is not simply one who denies the truth of religious belief, but one who believes we can enjoy meaningful, purposeful, and good lives without religion. And far from embracing moral nihilism, humanists are often deeply committed people, to be found at the forefront of many important ethical campaigns. Law goes on to show how the term humanism is used in a variety of ways. Marx described himself as a humanist but the Pope has also expressed support for what he calls humanism. Law argues for humanism as it is most commonly understood--as a positive, moral form of atheism.

    Readers meet a people highly skilled in sculpture, astronomy, city planning, poetry, and philosophy, who were also profoundly committed tocosmic regeneration through the thrust of the ceremonial knife and through warfare. Dav�d Carrasco looks beyond Spanish accounts that have colored much of the Western narrative to let Aztec voices speak about their origin stories, the cosmic significance of their capital city, their methods of childrearing, and the contributions women made to daily life and the empire. Carrasco discusses the arrival of the Spaniards, contrasts Aztec mythical traditions about the origins of their city with actual urban life in Mesoamerica, and outlines the rise of the Aztec empire. He also explores Aztecreligion, which provided both justification for and alternatives to warfare, sacrifice, and imperialism, and he sheds light on Aztec poetry, philosophy, painting, and especially monumental sculpture and architecture. He concludes by looking at how the Aztecs have been portrayed in Western thought, art, film, and literature as well as in Latino culture and arts.

    It asks questions such as: Do animals have moral rights? If so, what does this mean? What sorts of mental lives do animals have, and how should we understand welfare? By presenting models for understanding animals' moral status and rights, and examining their mental lives and welfare, David DeGrazia explores the implications for how we should treat animals in connection with our diet, zoos, and research. Animal Rights distinguishes itself by combining intellectual rigor with accessibility, offering a distinct moral voice with a non-polemical tone.

    Lyman Sargent discusses the role of utopianism in literature, and in the development of colonies and in immigration. The idea of utopia has become commonplace in social and political thought, both negatively and positively. Some thinkers see a trajectory from utopia to totalitarianism with violence an inevitable part of the mix. Others see utopia directly connected to freedom and as a necessary element in the fight against totalitarianism. In Christianity utopia is labelled as both heretical and as a fundamental part of Christian belief, and such debates are also central to such fields as architecture, town and city planning, and sociology among many othersSargent introduces and summarizes the debates over the utopia in literature, communal studies, social and political theory, and theology.ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area.

    Jan Westerhoff shows that the question "what is real?" is not some esoteric puzzle that only philosophers ponder. Scientists also ask this question when they investigate whether candidates for the fundamental constituents of matter are actually "out there" or just a mere abstraction from a successful theory and cognitive scientists ask it when trying to find out which set of the bewildering array of data processed by our brain could constitute the basis for the self.

    And yet it has excused, and even been thought to justify, the most reprehensible crimes. Why should this be? This Very Short Introduction explores this and other puzzling questions. Do we love someone for their virtue, their beauty, or their moral or other qualities? Are love's characteristic desires altruistic or selfish? Are there duties of love? What do the sciences - neuroscience, evolutionary and social psychology, and anthropology - tell us about love? Many of the answers we give to such questions are determined not so much by the facts of human nature as by the ideology of love. Ronald de Sousa considers some of the many paradoxes raised by love, looking at the different kinds of love - affections, affiliation, philia, storage, agape, but focusses on eros, or romantic love. He considers whether our conventional beliefs about love and sex are deeply irrational and argues that alternative conceptions of love and sex, although hard to formulate and live by, may be worth striving for.

    It has been explained as a combination of romance, science and prophecy; as a genre based on an imagined alternative to the reader's environment; and as a form of fantastic fiction and historical literature. It has also been argued that science fiction narratives are the most engaged, socially relevant, and responsive to the modern technological environment. This Very Short Introduction doesn't offer a history of science fiction, but instead ties examples of science fiction to different historical moments, in order to demonstrate how science fiction has evolved over time. David Seed looks not only at literature, but also at drama and poetry, as well as film. Examining recurrent themes in science fiction he looks at voyages into space, the concept of the alien and alternative social identities, the role of technology in science fiction, and its relation to time - in the past, present, and future.

    Featuring many striking photos, this Very Short Introduction offers a fascinating portrait of the unique world of each planet as well as an illuminating discussion of moons, asteroids, and Trans-Neptunian objects. Leading planetary scientist David A. Rothery, who has chaired the European Space Agency's Mercury surface and composition working group since 2007, gives a stimulating overview of the origin, nature, and evolution of our Solar System, including the controversial issues of what qualifies as a planet, and what conditions are required for a planetary body to support life. He explains how the surfaces of planets and moons have been sculpted by geology, weather, and impacts by meteors and asteroids. Rothery shows how our knowledge has advanced over the centuries, and how it has expanded at a dramatic rate in recent years, going far beyond our Solar System to explore planets orbiting distant stars.
