Nearly every regime today claims to be democratic, but not all democracies allow free politics, and free politics existed long before democratic franchises. This book is a short account of the history of the doctrine and practice of democracy, from ancient Greece and Rome through the American, French, and Russian revolutions, and of the usages and practices associated with it in the modern world. It argues that democracy is a necessary but not asufficient condition for good government, and that ideas of the rule of law, and of human rights, should in some situations limit democratic claims.

    Jonathan Culler, an extremely lucid commentator and much admired in the field of literary theory, offers discerning insights into such theories as the nature of language and meaning, and whether literature is a form of self-expression or a method of appeal to an audience. Concise yet thorough, Literary Theory also outlines the ideas behind a number of different schools: deconstruction, semiotics, postcolonial theory, and structuralism, among others. From topics such as literature and social identity to poetry, poetics, and rhetoric, Literary Theory: A Very Short Introduction is a welcome guide for anyone interested in the importance of literature and the debates surrounding it.About the Series: Combining authority with wit, accessibility, and style, Very Short Introductions offer an introduction to some of life's most interesting topics. Written by experts for the newcomer, they demonstrate the finest contemporary thinking about the central problems and issues in hundreds of key topics, from philosophy to Freud, quantum theory to Islam.

    It explains what algorithms do, how they are used, the risks associated with using them, and why governments should be concerned. Important areas arehighlighted, such as Stream Ciphers, block ciphers, public key algorithms, digital signatures, and applications such as e-commerce. This book highlights the explosive impact of cryptography on modern society, with, for example, the evolution of the internet and the introduction of more sophisticatedbanking methods.

    During his lifetime he worked as a civil servant and published only a handful of short stories, the best known being The Transformation. His other three novels, published after his death, helped to found his reputation as a uniquely perceptive interpreter of the twentieth century.Discussing both Kafka's crisis-ridden life and the subtleties of his art, Ritchie Robertson provides an intriguing and accessible look at the life of this fascinating author. Using Metamorphosis as a recurring example, Robertson shows how Kafka's work explores such characteristically modern themes as the place of the body in culture, the power of institutions over people, and the possibility of religion after Nietzsche had proclaimed the death of God.

    Travel fast enough and you could weigh as much as a jumbo jet, be flattened thinner than a CD without feeling a thing-and live forever! As for the angles of a triangle, they do not always have to add up to 180 degrees. And then, of course, there are black holes. These are but a few of the extraordinary consequences of Einstein's theory of relativity. It is now over a hundred years since he made these discoveries, and yet the general public is still largely unaware of them. Filled with illuminating anecdotes and fascinating accounts of experiments, this book aims to introduce the interested lay person to the subject of relativity in a way which is accessible and engaging and at the same time scientifically rigorous. With relatively few mathematical equations--nothing more complicated than the Pythagoras's Theorem--this VSI packs a lot time into very little space, and for anyone who has felt intimidated by Einstein's groundbreaking theory, it offers the perfect place to start.

    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.

    First, geologists realized that the continents themselves were drifting across the surface of the globe and that oceans were being created and destroyed. Secondly, pictures of the entire planet were returned from space. Suddenly, the Earth began to be viewed as a single entity; a dynamic, interacting whole, controlled by complex processes we scarcely understood. This Introduction explores emerging geological research and explains how new advances in the understanding of plate tectonics, seismology, and satellite imagery have enabled us to begin to see the Earth as it actually is: dynamic and ever changing.

    Moreover, groundbreaking research on genes, and especially key families of genes such as the Homeobox genes which controlthe development of body plans, has led to radical changes in the classification of animals. In this Very Short Introduction, Peter Holland presents a cutting-edge tour of the animal kingdom, providing an authoritative summary of the modern view of animal life, its origins, and the new classificationresulting from DNA studies. Beginning with the definition of animals (not obvious in biological terms), Holland takes the reader through the revolutionary new high-level groupings of animals (phyla) based on evolutionary relationships and ancestry. Ranging from corals and sponges to nematodes, seasquirts, and vertebrates, and illuminating many key topics in zoology, this fascinating, brief overview will be of great value to all students of the life sciences as well as providing a concise summary for the interested lay reader.

    Reynolds provides a general overview of the history of the subject as it has developed in English, at the same time introducing key debates, developments, and figures in the field. Reynolds demonstrates how writing for children--whether on page or screen--has helped in shaping ideas about culture, society and childhood. She also raises questions about the future of children's literature generally and discusses the shape that it might take.

    This Very Short Introduction looks at the importance accorded to the Bibleby different communities and cultures and attempts to explain why it has generated such a rich variety of uses and interpretations. It explores how the Bible was written, the development of the canon, the role of Biblical criticism, the appropriation of the Bible in high and popular culture, and itsuse for political ends.About the Series: Combining authority with wit, accessibility, and style, Very Short Introductions offer an introduction to some of life's most interesting topics.

    Scerri looks at the trends in properties of elements that led to the construction of the periodic table, and how the deeper meaning of its structure gradually became apparent with the development of atomic theory and quantum mechanics, so that physics arguably came to colonize an entirely different science, chemistry.

    Galileo's own beautifully lucid arguments are used in this volume to show how his scientific method was utterly divorced from the Aristotelian approach to physics; it was based on a search not for causes but for laws. Galileo's methods had an overwhelming significance for the development of modern physics, and they led to a final parting of the ways between science and philosophy. Now, in this extraordinary and concise introduction, Drake provides a stimulating view of Galileo's life and works, providing a fresh perspective on Galileo's methodology and his final incrimination.About the Series: Combining authority with wit, accessibility, and style, Very Short Introductions offer an introduction to some of life's most interesting topics.

    This is an exploration of her relationship with the literary form we have come to know as "science fiction,” a relationship that has been lifelong, stretching from her days as a child reader in the 1940s, through her time as a graduate student at Harvard, where she worked on the Victorian ancestor of the form, and continuing as a writer and reviewer.  This book brings together her three heretofore unpublished Ellmann Lectures from 2010: "Flying Rabbits," which begins with Atwood's early  rabbit superhero creations, and goes on to speculate about masks, capes, weakling alter egos, and Things with Wings; "Burning Bushes," which follows her into Victorian otherlands and beyond; and "Dire Cartographies," which investigates Utopias and Dystopias.  In Other Worlds also includes some of Atwood's key reviews and thoughts about the form. Among those writers discussed are Marge Piercy, Rider Haggard, Ursula Le Guin, Ishiguro, Bryher, Huxley, and Jonathan Swift. She elucidates the differences (as she sees them) between "science fiction" proper, and "speculative fiction," as well as between "sword and sorcery/fantasy" and "slipstream fiction." For all readers who have loved The Handmaid's Tale, Oryx and Crake, and The Year of the Flood, In Other Worlds is a must.  From the Hardcover edition.

    This Very Short Introduction presents a succinct guide to the key episodes in that story - from the very origins of life four million years ago to the extraordinary diversity of species around the globe today.Beginning with an explanation of the controversies surrounding the birth of life itself, each following chapter tells of a major breakthrough that made new forms of life possible: including sex and multicellularity, hard skeletons, and the move to land. Along the way, we witness the greatest mass extinction, the first forests, the rise of modern ecosystems, and, most recently, conscious humans.Introducing ideas from a range of scientific disciplines, from evolutionary biology and earth history, to geochemistry, palaeontology, and systematics, Michael Benton explains how modern science pieces the evidence in this vast evolutionary puzzle together, to build up an accessible and up-to-date picture of the key developments in the history of life on earth.

    Following a brief account of the historical relationship between structuralism and poststructuralism, this Very Short Introduction traces the key arguments that have ledpoststructuralists to challenge traditional theories of language and culture. While the author discusses such well-known figures as Barthes, Foucault, Derrida, and Lacan, she also draws pertinent examples from literature, art, film, and popular culture, unfolding the poststructuralist account ofwhat it means to be a human being.About the Series: Combining authority with wit, accessibility, and style, Very Short Introductions offer an introduction to some of life's most interesting topics.
