Allan Hobson provides a new and increasingly complete picture of how dreaming is created by the brain. Focusing on dreaming to explain the mechanisms of sleep, this book explores how the new science of dreaming is affecting theories in psychoanalysis, and how it is helping our understanding of the causes of mental illness.J. Allan Hobson investigates his own dreams to illustrate and explain some of the fascinating discoveries of modern sleep science, while challenging some of the traditionally accepted theories about the meaning of dreams. He reveals how dreaming maintains and develops the mind, why we go crazy in our dreams in order to avoid doing so when we are awake, and why sleep is not just good for health but essential for life.

    In this Very Short Introduction, one of the world's leading authorities on the philosophy of information and on information ethics, Luciano Floridi, offers an illuminating exploration of information as it relates to both philosophy and science. He discusses the roots of the concept of information in mathematics and science, and considers the role of information in several fields, including biology. Floridi also discusses concepts such as "Infoglut" (too much information to process) and the emergence of an information society, and he addresses the nature of information as a communication process and its place as a physical phenomenon. Perhaps more important, he explores information's meaning and value, and ends by considering the broader social and ethical issues relating to information, including problems surrounding accessibility, privacy, ownership, copyright, and open source. This book helps us understand the true meaning of the concept and how it can be used to understand our world.About the Series: Combining authority with wit, accessibility, and style, Very Short Introductions offer an introduction to some of life's most interesting topics.

    In this lively and accessible introduction, Graham Priest shows how wrong this conception is. He explores the philosophical roots of the subject, explaining how modern formal logic deals with issues ranging from the existence of God and the reality of time to paradoxes of probability and decision theory. Along the way, the basics of formal logic are explained in simple, non-technical terms, showing that logic is a powerful and exciting part of modern philosophy.About the Series: Combining authority with wit, accessibility, and style, Very Short Introductions offer an introduction to some of life's most interesting topics.

    These, along with the introduction of the oral contraceptive, have altered all of our lives. There has also been an increase in the recreational use and abuse of drugs in the Western world. This Very Short Introduction gives a non-technical account of how drugs act on the body and how therapeutic drugs are developed and tested, then goes on to review both legal (prescription, alcohol, nicotine, and caffeine) and illegal drugs, and discuss current ideas about why some drugs are addictive, and whether drug laws need reform.

    The authors introduce the general reader to some of the most important basic findings, concepts, and procedures of evolutionary biology, as it has developed since the first publications of Darwin and Wallace on the subject, over 140 years ago. They show how evolution provides a unifying set of principles for the whole of biology and sheds light on the relation of human beings to the universe and each other.

    During his reign he conquered the Achaemenid Persian Empire, the largest empire that had ever existed, leading his army from Greece to Pakistan, and from the Libyan desert to the steppes of Central Asia. His meteoric career, as leader of an alliance of Greek cities, Pharaoh of Egypt, and King of Persia, had a profound effect on the world he moved through. Even in his lifetime his achievements became legendary and in the centuries that following his story was told and retold throughout Europe and the East. Greek became the language of power in the Eastern Mediterranean and much of the Near East, as powerful Macedonian dynasts carved up Alexander's empire into kingdoms of their own, underlaying the flourishing Hellenistic civilization that emerged after his death.But what do we really know about Alexander? In this Very Short Introduction, Hugh Bowden goes behind the usual historical accounts of Alexander's life and career. Instead, he focuses on the evidence from Alexander's own time -- letters from officials in Afghanistan, Babylonian diaries, records from Egyptian temples -- to try and understand how Alexander appeared to those who encountered him. In doing so he also demonstrates the profound influence the legends of his life have had on our historical understanding and the controversy they continue to generate worldwide.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.

    Aristotle wrote an important treatise on it and Demosthenes remains famous to this day for his skills as a rhetorician. But skill with rhetoric today is no longer admired. Rhetoric is often seen as a synonym for shallow, deceptive language-empty words, empty rhetoric--and therefore as something quite negative. But if we view rhetoric in more neutral terms, as the art of persuasion, it is clear that we are all forced to engage with it at some level, if only because we are constantly exposed to the rhetoric of others. In this Very Short Introduction, Richard Toye explores the purpose of rhetoric. Rather than presenting a defense of it, he considers it as the foundation-stone of civil society, and an essential part of any democratic process. Using wide-ranging examples from ancient Greece, medieval Islamic preaching, the wartime speeches of Winston Churchill, and modern cinema, Toye considers why we should all have an appreciation of the art of rhetoric.About the Series:Oxford's Very Short Introductions series offers concise and original introductions to a wide range of subjects--from Islam to Sociology, Politics to Classics, Literary Theory to History, and Archaeology to the Bible.

    This Very Short Introduction, addresses a variety of questions, including what a black hole actually is, how they are characterized and discovered, and what would happen if you came too close to one. Professor Katherine Blundell looks at the seemingly paradoxical, mysterious, and intriguing phenomena of black holes. Outlining their nature and characteristics, both those resulting from the spectacular collapse of heavy stars, and the giant black holes found at the centres of galaxies, she separates scientific fact from science fiction, and demonstrates the important role they play in the cosmos.

    But as Morris Rossabi reveals in this VeryShort Introduction, within two generations of their bloody conquests, the Mongols evolved from conquerors and predators to wise rulers who devised policies to foster the economies of the lands they had subjugated. By adopting political and economic institutions familiar to the local populations andrecruiting native officials, they won over many of their non-Mongol subjects. In addition, Mongol nobles were ardent patrons of art and culture, supporting the production of Chinese porcelains and textiles, Iranian tiles and illustrated manuscripts, and Russian metalwork. Perhaps most important, thepeace imposed by the Mongols on much of Asia and their promotion of trade resulted in considerable interaction among merchants, scientists, artists, and missionaries of different ethnic groups--including Europeans. Modern Eurasian and perhaps global history starts with the Mongol empire.

    This book gives a lucid, exciting, and accessible account of the surprising and counterintuitive ideas that shape our understanding of the sub-atomic world. It does not disguise the problems of interpretation that still remain unsettled 75 years after the initial discoveries. The main text makes no use of equations, but there is a Mathematical Appendix for those desiring stronger fare. Uncertainty, probabilistic physics, complementarity, the problematic character of measurement, and decoherence are among the many topics discussed. This volume offers the reader access to one of the greatest discoveries in the history of physics and one of the outstanding intellectual achievements of the twentieth century.About the Series: Combining authority with wit, accessibility, and style, Very Short Introductions offer an introduction to some of life's most interesting topics.

    How then did it come to be that there was a Second World War causing twiceas much loss of life and more destruction than any other previous conflict? In this Very Short Introduction, Gerhard L. Weinberg provides an introduction to the origins, course, and impact of the war on those who fought and the ordinary citizens who lived through it. Starting by looking at the inter-war years and the German invasion of Poland in September 1939, he examines how the war progressed by examining a number of key events, including the war in the West in 1940, Barbarossa, the German Invasion of the Soviet Union, the expansion of Japan's war with China, developments on the home front, and the Allied victory from 1944-45. Exploring the costs and effects of the war, Weinberg concludes by considering the long-lasting mark World War II has left on society today.

    During that time, it has spread among the neighboring peoples - the Mongol, Himalayan, and Siberian peoples, Manchus and Chinese. At its height is has been practiced in regions as far west as the Volga river and to the east in Beijing. Its capacity for creative adaptation is demonstrated by its recent growth in Europe and America. At the same time, it is at the center of political contestation in ethnically Tibetan regions of China, while its best known exponent, the Dalai Lama, has become one of the most admired religious leaders in the world today. But what does this religion teach? Just what is the position of the Dalai Lama, and how will his succession be assured? Is it true that Tibetan Buddhism in entirely suppressed in China? Scholar Matthew Kapstein offers a brief account responding to these questions and more in this Very Short Introduction, in terms that are accessible to students, general readers, journalists, and others who are curious to learn the most essential features of Tibetan Buddhist history, teachings, and practice.
