Ancient Near Eastern Studies2. Bible and Biblical Studies3. Judaism and Jewish Studies4. The Quran and Quranic Studies5. Islam and Islamic StudiesNoegel and Wheeler treat each entry as a compilation of relevant data culled from these different traditions in order to take the reader beyond the expected parameters of research. Originally envisioned as an initial resource for students of comparative religion, the extensive chronology, bibliography, list of acronyms, and the overall accessibility of the passages make the Dictionary suitable for a much wider audience.

The decline of institutionalized religion in the increasingly secularized West has been offset by the contemporary spiritual development understood in the form of emerging New Age movements. This Dictionary presents the potpourri of spiritual and psycho-physical therapeutic practices associated with this affirmation of the individual's spiritual freedom, the expectation of a future golden age, the emphasis on self-development and the holistic pluralism that sets the dominant pulse for innovative spirituality in the twenty-first century.

Academic philosopher, logician, public intellectual, educator, political activist, and freethinker, Bertrand Russell was and remains a colossus. No other single philosopher in the last 200 years can be said to have created so much and influenced so many. His Principia Mathematica, written with A. N. Whitehead, ranks as one of the greatest books on logic since Aristotle. His philosophical work on language, meaning, logic, mind, and metaphysics formed the basis of 20th-century philosophy.

Aesthetics is not a "factual" discipline; there are no aesthetic facts. The word itself is derived from the Greek word for "feeling" and the discipline arises because of the need to find a place for the passions within epistemology—the branch of philosophy that investigates our beliefs. Aesthetics is more than just the study of beauty; it is a study of that which appeals to our senses, most often in connection with the classification, analysis, appreciation, and understanding of art.The Historical Dictionary of Aesthetics covers its history from Classical Greece to the present, including entries on non-western aesthetics. The book contains a chronology, a list of acronyms and abbreviations, an introductory essay, a bibliography, and hundreds of cross-referenced dictionary entries on the main concepts, terminology, important persons (philosophers, critics, and artists), and the rules and criteria we apply in making judgments on art.

This is done through a chronology, an introductory essay, a bibliography, and over 700 cross-referenced dictionary entries.

The Protestant Reformation of the 16th century has traditionally been viewed as marking the onset of modernity in Europe. It finally broke up the federal Christendom of the middle ages, under the leadership of the papacy and substituted for it a continent of autonomous and national states, independent of Rome.The Historical Dictionary of the Reformation and Counter-Reformation provides a comprehensive account of two chains of events—the Protestant Reformation and the Catholic Counter-Reformation—that have left an enduring imprint on Europe, America, and the world at large. This is done through a chronology, an introductory essay, a bibliography, and over 300 cross-referenced dictionary entries on persons, places, countries, institutions, doctrines, ideas, and events.

It is much harder to define a religious movement than it is to define a religion or denomination. That applies especially when that movement almost defies definition as the Holiness Movement does. The Holiness Movement is a Methodist religious renewal movement that has over 12 million adherents worldwide. Perhaps the most familiar public manifestation of the holiness movement has been its urban holiness missions, and the Salvation Army—noted for its service ministries among poor and people suffering the dislocations that accompany war and disaster—is the most notable example.In the second edition of the Historical Dictionary of the Holiness Movement, important new developments in the Holiness Movement—such as the widely discussed "Holiness Manifesto"—are thoroughly discussed, and the content has also been expanded to include information on figures from Asia and Africa to reflect the continued growth of the Holiness Movement. With a chronology, an introductory essay, a bibliography, and over 400 cross-referenced dictionary entries, this reference has information that cannot be found elsewhere.

Metaphysics is what Aristotle described as "the First Philosophy" or "first science," a comprehensive inquiry into the ultimate nature of reality.

For almost four thousand years, men and women with power have exploited vulnerable populations for cheap or free labor. These slaves, serfs, helots, tenants, peons, bonded or forced laborers, etc., built pyramids and temples, dug canals and mined the earth for precious metals and gemstones.

The history of sexuality is central to social history, the history of ideas, the realization or repression of human rights, and other areas of focus. This is also true about those who have had, or do have, what could be called minority sexualities. Same-sex attraction has generally been a minority sexuality; it has been the object of tremendous repression and vociferous complaint but also one of praise by talented poets and philosophers. The Historical Dictionary of Homosexuality provides a comprehensive survey of same-sex relations from ancient China and Greece to the contemporary world.It covers the gay rights movement from its origins in 19th century Europe to the nascent global network today.

The fiftieth anniversary of many major milestones in what is commonly called the African-American Civil Rights Movement was celebrated in 2013. Fifty years removed from the Birmingham campaign, the assassination of Medgar Evers, and the March on Washington and it is clear that the sacrifices borne by those generations in that decade were not in vain.

New religious movements—commonly known as cults—are defined as organizations that have arisen within the last 200 years. Most treatments of these movements have typically resorted to sensationalism rather than objectivity, and New religious movements tend to receive negative media publicity. Despite their unfavorable portrayal in popular culture, however, new religious movements are a global phenomenon and much remains to be studied about these movements.In this newly updated second edition of the Historical Dictionary of New Religious Movements, George D. Chryssides traces the rise and development of new religious movements throughout the world.

This book is an excellent access point for students, researchers, and anyone wanting to know more about new religious movements.

Organized labor is about the collective efforts of employees to improve their economic, social, and political position. It can be studied from many different points of view—historical, economic, sociological, or legal—but it is fundamentally about the struggle for human rights and social justice. As a rule, organized labor has tried to make the world a fairer place. Even though it has only ever covered a minority of employees in most countries, its effects on their political, economic, and social systems have been generally positive. History shows that when organized labor is repressed, the whole society suffers and is made less just.The Historical Dictionary of Organized Labor looks at the history of organized labor to see where it came from and where it has been. This is done through a chronology, an introductory essay, appendixes, a glossary of terms, and an extensive bibliography. The dictionary section has over 400 cross-referenced entries on most countries, international as well as national labor organizations, major labor unions, leaders, and other aspects of organized labor such as changes in the composition of its membership.

The modern reputation of Friends in the United States and Europe is grounded in the relief work they have conducted in the presence and aftermath of war. Friends (also known as Quakers) have coordinated the feeding and evacuation of children from war zones around the world. They have helped displaced persons without regard to politics. They have engaged in the relief of suffering in places as far-flung as Ireland, France, Germany, Ethiopia, Egypt, China, and India. Their work was acknowledged with the award of the Nobel Peace Prize in 1947 to the American Friends Service Committee (AFSC) and the Friends Service Council of Great Britain. More often, however, Quakers live, worship, and work quietly, without seeking public attention for themselves. Now, the Friends are a truly worldwide body and are recognized by their Christ-centered message of integrity and simplicity, as well as their nonviolent stance and affirmation of the belief that all people—women as well as men—may be called to the ministry.The expanded second edition of the Historical Dictionary of the Friends (Quakers) relates the history of the Friends through a chronology, an introductory essay, an extensive bibliography, and over 700 cross-referenced dictionary entries on concepts, significant figures, places, activities, and periods.

One of Japan's major religions, Shinto has no doctrines and there are no sacred texts from which religious authority can be derived. It does not have an identifiable historical founder, and it has survived the vicissitudes of history through rituals and symbols rather than through continuity of doctrine. Shinto is primarily a religion of nature, centered on the cultivation of rice, the basis of a culture with which the western world is not familiar in terms of either its annual cycle or the kind of lifestyle it generates. The roots of the Shinto tradition probably precede this and reflect an awareness of the natural order. The oldest shrines came to be located in places that inspired awe and wonder in their observers, such as the great Fall of Nachi in Kumano, or in mountains that conveyed a sense of power.The expanded second edition of the Historical Dictionary of Shinto relates the history of Shinto through a chronology, an introductory essay, an extensive bibliography, and over 800 cross-referenced dictionary entries on Shinto concepts, significant figures, places, activities, and periods. Scholars and students will find the overviews and sources for further research provided by this book to be enormously helpful.

There are several eras in the history of Christianity radical forms of the tradition are obvious: the early church of the first five centuries, the medieval era, the age of reform, the early modern era, and the contemporary era. Radical Christian activity and experience may reflect either a primary or a derived level of spirituality. New converts may join a sect or movement with radical characteristics; or they may become dissatisfied with their initial Christian experiences and desire a different or deeper Christian spirituality, usually closely parallel to that seen in the New Testament.The Historical Dictionary of Radical Christianity covers the history of this movement and includes an introductory essay and a bibliography. The dictionary section has over 400 cross-referenced entries. The dictionary entries selected reflect the leading groups, movements, and sects from each major era of Christian history. Especially in the contemporary period, the great proliferation of radical thinkers and groups has necessitated a selection process with those selected exhibiting sustained group activity, possessing an identifiable following, and demonstrating a significant cultural impact. This book is an excellent access point for students, researchers, and anyone wanting to know more about Radical Christianity.

Calvinism is named after 16th century Reformer, John Calvin whose overall theology is contained in his Institutes of the Christian Religion (1559). Calvin's theology and ecclesiology provided the foundation upon which the Reformed Churches of Europe were built.

Not so long ago hardly anything was said of the Lesbian Liberation Movement and the Gay Liberation Movement, indeed, the terms gay and lesbian were not even used if some other expression could be found. Today, by contrast, hardly a day passes when something important does not occur, and is carried by the major media and disseminated on more personal levels through blogs and the social media. If anything, there is perhaps too much “news” and not enough “information.” Obviously, a book like this cannot keep up with the news, but it can do something equally important when it comes to information, by reminding us of the past and what has been going and just how fast events are moving. The Historical Dictionary of the Lesbian and Gay Liberation Movements covers the history of this movement through a cross-referenced dictionary with over 1000 entries on specific countries and regions, influential historical figures, laws that criminalized same-sex sexuality, various historical terms that have been used to refer to aspects of same-sex love, and contemporary events and legal decisions. Including a comprehensive chronology and bibliography, this book is an excellent access point for students, researchers, and anyone interested in learning more about the struggle for equality.

The Reformation of the 16th century was a complex and multifaceted political, social, cultural, and religious process. Most historians agree, however, that in the framework of this process it was the religious and theological efforts to reform and renew the late medieval church—decadent and irrelevant in many ways—that were the initiating forces that set a broad historical movement in motion. Among these reforming religious and theological forces, the Lutheran reform movement was the most important and influential one. It was the historical impact of the theological genius of the Wittenberg professor Martin Luther (1483-1546) that profoundly changed and shaped the face of Europe and beyond. Today, Lutheranism has become a worldwide communion of churches that stretches from Germany to Siberia, Papua New Guinea, Madagascar, and Surinam.The second edition of the Historical Dictionary of Lutheranism presents information on major theological issues, historical developments of Lutheranism worldwide, Lutheran ecumenical and missionary involvement and activities, worship and liturgy, spirituality, social ethics, inter-religious and Jewish relations, Lutheranism and the arts, theology, and important representatives of Lutheranism.

This book is an excellent access point for students, researchers, and anyone wanting to know more about Lutheranism.

Witchcraft has proven an important, if difficult, historical subject to investigate and interpret over the last four decades or so. Modern historical research into witchcraft began as an attempt to tease out the worldview of ordinary people in 16th- and 17th-century England, but it quickly expanded to encompass the history of witchcraft in most cultures and societies that have existed with scholarly studies now extending back to the time of earliest law code that punished sorcery, the Babylonian Code of Hammurabi (1792-1750 B.C.E.), and forward to the last witchcraft cases in England, those of Helen Duncan and Jane Yorke, tried in 1944. There has also been a significant amount of interest in the development of the modern religion of witchcraft, or Wicca, as various forms of neo-paganism continue to attract adherents.The second edition of Historical Dictionary of Witchcraft covers the history of the Witchcraft from 1750 B.C.E. though the modern day. This is done through a chronology, an introductory essay, and an extensive bibliography. The dictionary section has over 300 cross-referenced entries on witch hunts, witchcraft trials, and related practices around the world. This book is an excellent access point for students, researchers, and anyone wanting to know more about the history of witchcraft.

Jesus of Nazareth is arguably the most famous and influential human being who has ever lived on earth. In the Historical Dictionary of Jesus, author Daniel J. Harrington delves into the ancient literary sources about Jesus, modern methods of approaching these sources, the major events in Jesus' life, persons and places associated with him, the form and content of his teachings, what can be said about his death and the claim that he was raised from the dead, and the contributions of major modern scholars to the quest of the historical Jesus.The book consists of three parts: an introduction to the major topics pertaining to Jesus as a historical figure; a cross-referenced dictionary containing 400 entries on a range of topics, including things Jesus did and said, ancient sources of historical data, and modern scholarship and interpretation; and a bibliography listing some of the most important books related to Jesus and the world in which he lived. This concise and objective reference work provides a clear and accurate introduction to the study of Jesus as a historical figure.

The most broadly accepted explanation of Sufism i the etymological derivation of the term from the Arabic for “wool,” ?uf, associating practitioners with a preference for poor, rough clothing. This explanation clearly identifies Sufism with ascetical practice and the importance of manifesting spiritual poverty through material poverty. In fact, some of the earliest “Western” descriptions of individuals now widely associated with the larger phenomenon of Sufism identified them with the Arabic term faqir, mendicant, or its most common Persian equivalent, darwish. Sufism, as presented here embraces a host of features including the ritual, institutional, psychological, hermeneutical, artistic, literary, ethical, and epistemological.This second edition of Historical Dictionary of Sufism contains a chronology, an introduction, a glossary, and an extensive bibliography. The dictionary section has over 1,000 cross-referenced entries on important personalities, major historical figures and movements, practices, economy, foreign relations, religion, and culture.
