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.

    Was late antiquity therefore merely a time of decline? In this vibrant and compact introduction, Gillian Clark shedslight on the concept of late antiquity and the events of its time, showing that this was in fact a period of great transformation. Late antiquity saw Roman law codified, Christian creeds formulated, the Talmud compiled, and the Qur'an composed. If the Goths sacked the city of Rome, the Vandalsbuilt churches in Africa and Attila the Hun received an embassy from Constantinople. Anthony of Egypt and Simeon Stylites offered spectacular new models of holiness, while Augustine and Basil and Benedict devised rules for monastic communities. Late antique artists produced the mosaics of Ravennaand the first dome of Hagia Sophia. And it was also the period when emperors Diocletian in the third century and Justinian in the sixth enacted extensive and much-needed reforms of government.

    The author illustrates important aspects of Africa's history with a range of fascinating historical examples, drawn from over 5 millennia across this vast continent. The multitude of topics that the reader will learn about in this succinct work include the unity and diversity of African cultures, slavery, religion, colonial conquest, the diaspora, and the importance of history in understanding contemporary Africa. The book examines questions such as: Who invented the idea of "Africa"? How is African history pieced together, given such a lack of documentary evidence? How did Africa interact with the world 1,000 years ago? Africa has been known as 'the cradle of mankind', and its recoverable history stretches back to the Pharaohs. But the idea of studying African history is itself new, and the authors show why it is still contested and controversial. This VSI, the first concise work of its kind, will prove essential reading for anyone interested in the African continent and the diversity of human history.

    Ostracized by the Jewishcommunity in Amsterddam to which he was born, Spinoza developed a political philosophy that set out to justify the secular state ruled by a liberal constitution, and a metaphysics that sought to reconcile human freedom with a belief in scientific explanation. Here, Roger Scruton presents a clear andsystematic analysis of Spinoza's thought and shows its relevance to today's intellectual preoccupations.

    It tackles many questions, such as: What accounts for the perpetuation of ethnic and religious conflict in Ireland? Why has armedviolence proven so hard to control? Who are the major figures and issues in the conflict? Can we expect more Northern Irelands in the future?

    Now, in The American Presidency, presidential authority Charles O. Jones provides invaluable background to the current controversy, in a compact, reliable guide to the office of the chief executive.This marvelously concise survey is packed with information about the presidency, some of it quite surprising. We learn, for example, that the Founders adopted the word president over governor and other alternatives because it suggested a light hand, as in one who presides, rather than rules. Indeed, the Constitutional Convention first agreed to a weak chief executive elected by congress for one seven-year term, later calling for independent election and separation of powers. Jones sheds much light on how assertive leaders, such as Andrew Jackson, Theodore Roosevelt, and FDR enhanced the power of the presidency, and illuminating how such factors as philosophy (Reagan's anti-Communist conservatism), the legacy of previous presidencies (Jimmy Carter following Watergate), relations with Congress, and the impact of outside events have all influenced presidential authority. He also explores the rise of federal power and the dramatic expansion of federal agencies, showing how the president takes a direct hand in this vast bureaucracy, and he examines the political process of selecting presidents, from the days of deadlocked conventions to the rise of the primary after World War II.In 200 years, he writes, the presidency had changed from that of a person--Washington followed by Adams, then Jefferson--to a presidential enterprise with a cast of thousands. Jones explains how this remarkable expansion has occurred and where it may lead in the future.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 growing number of patients being diagnosed with depression, ADD, alcoholism, and other illnesses mean that few people are not touched by it. This book provides a valuable and comprehensible introduction to the subject. It starts with the history of its development as a scientific field, including the identification of major mental illnesses, the rise and fall of the asylum system, and the flourishing of psychoanalysis and other psychotherapies. More than any other branch of medicine, psychiatry has been attacked and criticized. There is a long list of perceived horrors--patient abuse, bizarre medical experiments, mind-control by evil governments, coercion by maniacal hypnotists. Modern psychiatry brings with it new controversies, such as the perceived over-prescription of antidepressants and behavior modifiers for children and teens, or unchecked marketing power of drug companies. This book does not draw conclusions on these issues, but rather provides the reader with a clear understanding of what psychiatry is, and what it does, so that they can draw their own. It is a great reference for anyone with an interest in mental illness and its treatment, students of psychiatry, medicine, psychology, and history of science, and health professionals.

    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.

    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.

    Even today, the war inspires countless articles and books, extensive archaeological excavations, movies, television documentaries, even souvenirs and collectibles. Butwhile the ancients themselves believed that the Trojan War took place, scholars of the modern era have sometimes derided it as a piece of fiction.Combining archaeological data and textual analysis of ancient documents, this Very Short Introduction considers whether or not the war actually took place and whether archaeologists have really discovered the site of ancient Troy. To answer these questions, archaeologist and ancient historian EricH. Cline examines various written sources, including the works of Homer, the Epic Cycle (fragments from other, now-lost Greek epics), classical plays, and Virgil's Aeneid. Throughout, the author tests the literary claims against the best modern archaeological evidence, showing for instance thatHomer, who lived in the Iron Age, for the most part depicted Bronze Age warfare with accuracy. Cline also tells the engaging story of the archaeologists--Heinrich Schliemann and his successors Wilhelm Dörpfeld, Carl Blegen, and Manfred Korfmann--who found the long-vanished site of Troy throughexcavations at Hisarlik, Turkey.Drawing on evidence found at Hisarlik and elsewhere, Cline concludes that a war or wars in the vicinity of Troy probably did take place during the Late Bronze Age, forming the nucleus of a story that was handed down orally for centuries until put into final form by Homer. But Cline suggests that, even allowing that a Trojan War took place, it probably was not fought because of Helen's abduction, though such an incident may have provided the justification for a war actually fought for more compelling economic and political motives.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.

    Aquinas was a controversial figure in his time who was often engaged in fierce theological debates. He was the foremost classical proponent of naturaltheology, and the father of the Thomistic school of philosophy and theology. This Very Short Introduction will look at Aquinas in a historical context, and explore the Church and culture into which Aquinas was born. It will consider Aquinas as philosopher and theologian, and will look at therelationship between philosophy and religion in the thirteenth century. Fergus Kerr, in this engaging and informative introduction, makes the Summa Theologiae, Aquinas's greatest single work, accessible to new readers. He also sheds valuable light on the importance of Thomas Aquinas in modern times, showing why Aquinas matters now, illustrating the significant role that the writings of Aquinas play in contemporary debate.

    After meeting with Americans on extensive travels in the United States, and intense study of documents and authorities, he authored the landmark Democracy in America, publishing its two volumes in 1835 and 1840. Ever since, this book has been the best source for every serious attempt to understand America and democracy itself. Yet Tocqueville himself remains a mystery behind the elegance of his style. Now one of our leading authorities on Tocqueville explains him in this splendid new entry in Oxford's acclaimed Very Short Introduction series. Harvey Mansfield addresses his subject as a thinker, clearly and incisively exploring Tocqueville's writings--not only his masterpiece, but also his secret Recollections, intended for posterity alone, and his unfinished work on his native France, The Old Regime and the Revolution. Tocqueville was a liberal, Mansfield writes, but not of the usual sort. The many elements of his life found expression in his thought: his aristocratic ancestry, his ventures in politics, his voyages abroad, his hopes and fears for America, and his disappointment with France. All his writings show a passion for political liberty and insistence on human greatness. Perhaps most important, he saw liberty not in theories, but in the practice of self-government in America. Ever an opponent of abstraction, he offered an analysis that forces us to consider what we actually do in our politics--suggesting that theory itself may be an enemy of freedom. And that, Mansfield writes, makes him a vitally important thinker for today. Translator of an authoritative edition of Democracy in America, Harvey Mansfield here offers the fruit of decades of research and reflection in a clear, insightful, and marvelously compact introduction.
