Science Analysis

First published in 1996, Our Ecological Footprint sets out a powerful model for visualizing and measuring humanity's impact on the Earth - the ecological footprint - with the aim of reducing the harm we are causing the planet before it is too late. Although numerous organizations, governments, and individuals worldwide have now adopted the concept of ecological footprinting, the idea has also proved to be controversial.

Max Weber was the first to identify beliefs and practices that influenced economic behavior. He found Catholics generally less motivated to succeed in business than Protestants because of their religious belief that everyone could achieve salvation. The branch of Protestants known as Calvinists, on the other hand, believed God determined everyone's salvation status before birth. Nothing a person might do on earth could save a soul marked for damnation.

Social anthropologist Edward Evans-Pritchard wrote Witchcraft, Oracles, and Magic Among the Azande after 20 months' fieldwork with the Azande people of the South Sudan. It became the founding text in the anthropology of witchcraft, and has been hailed as a classic. Although Witchcraft had little impact when it first appeared in 1937, its popularity grew after World War II. Alongside his subsequent work on the Nuer people, Witchcraft established Evans-Pritchard's reputation as an important anthropologist.

American sociologist and priest Jay MacLeod's 1987 work Ain't No Makin' It is groundbreaking for the novel way it combines field research with theory. The book follows the lives of two groups of young men from a low-income housing project in the greater Boston area. In it, MacLeod shows how poor people who aspire to live the American dream face many more obstacles than their middle-class counterparts.

In his 1996 book The Clash Of Civilizations and the Remaking of World Order, American political scientist Samuel Huntington sets out his vision of the post-Cold War world. While the era from 1945 to 1989 was shaped by ideological conflict (communism vs. capitalism), Huntington predicts a future of cultural conflict.

Published in 1996, Arjun Appadurai's Modernity at Large is an edited collection of earlier essays that had already made the Indian-born anthropologist an influential figure in his field of cultural anthropology. Appadurai here presents a theory of globalization, and suggests ways that other researchers can follow up on his ideas. Many of them continue to do so. For anthropologists, the book offered new ways of thinking about how communities are affected by globalization.

In her original and controversial 2005 book Politics of Piety: The Islamic Revival and the Feminist Subject Saba Mahmood examines the women's mosque movement in Cairo, Egypt as part of a wider turn to religious fervor integral to the broader Islamic revival of the twenty-first century. Mahmood's research suggests that in choosing to embrace the norms of their faith, these pious Muslim women are not limiting, but rather affirming, themselves.

Published by sociologist and historian W. E. B. Du Bois in 1903, this series of essays addresses the plight of African Americans facing everyday racism in the United States at the turn of the 20th century. It has become one of the most important works on race and identity across the world. Du Bois sets out to explain how black interaction with a white world has caused psychological anguish and argues that blacks should demand total equality in their daily realities.

In 2009's Liquidated, anthropologist Karen Z. Ho takes the tools of ethnographic research, which are traditionally used to study distant societies, and instead uses them to dissect the culture of high finance on New York's famous Wall Street. Through close observation of the daily lives of the bankers working there, and the beliefs, rituals, and timeframes that define them, Ho uncovers a distinct culture in which she finds the ultimate causes of the financial crises of recent times.

The era after World War II saw America's urban planners treat the lives of city-dwellers with disdain. It spawned a philosophy of urban renewal that valued the efficient movement of cars more than it valued the lives of people, and that wiped out entire neighborhoods dismissed by bureaucrats as slums. Published in 1961, Jane Jacobs's The Death and Life of Great American Cities examines the shortsightedness and failure of this philosophy. The book turns away from strict statistical study and abstract planning theory in favor of observations.

Plato imagines a dinner party - a symposium - held in the Athens of the late fifth century BC. He invites seven important historical figures including the philosopher Socrates, the comic playwright Aristophanes, and the notorious military general Alcibiades. As entertainment, each guest gives a speech praising eros (human love or erotic desire). Plato then "collects" these seven speeches into Symposium.

In his 1997 work Guns, Germs, and Steel, American geography professor and environmental historian Jared Diamond looks to answer the question of why human history unfolded differently on different continents, and why power and wealth became distributed as they are.

Published in 1990, The Anti-Politics Machine is American anthropologist James Ferguson's first book. It discusses international development projects: how they are conceived, researched, and put into practice. Importantly, it also looks at what these projects actually achieve. Ferguson is critical of the idea of development and argues that the process does not take enough account of the daily realities of the communities it is intended to benefit.

The history of philosophy is beset by unresolved disputes. These disputes are passed down from generation to generation as problems to be solved. If not solved, they engender skepticism. Philosophical disputes, posed as problems, can be resolved or dissolved if we first acknowledge that some things are clear to reason.

Environmental factors shape our history just as much as - and sometimes more than - human factors. That's the premise of Alfred W. Crosby's 1972 work The Columbian Exchange: Biological and Cultural Consequences of 1492, a key text in environmental history.

Social capital - the relationships between people that allow communities to function well - has long been recognized as the grease that oils the wheels of society. It facilitates trust, creates bonds among neighbors, and even helps boost employment. In his 2000 book, Bowling Alone, American sociologist Robert Putnam argues that Americans have become disconnected from one another and from the institutions of their common life and investigates the consequences of this change.

Philosopher Judith Butler's 1990 work, Gender Trouble, shook the foundations of feminist theory and changed the conversation about gender. While many thinkers already accepted that "gender" was a category constructed by society rather than defined by one's genitalia, Butler went further and argued that gender is performative - it exists only in the acts that express it. Society determines that wearing makeup is "feminine" - but some men wear makeup. Are they "women"?

Philosopher Mary Wollstonecraft's 1792 work A Vindication of the Rights of Woman is a key text in the development of what we now know as feminism. Written in the atmosphere created by the French Revolution, which made radical change seem possible, Wollstonecraft's work challenges the idea that society's oppression of women is entirely natural. While her male contemporaries happily argued for the fundamental freedoms of all men, few were interested in extending these revolutionary rights to women.

Our Common Future is a joint work produced in 1987 by a United Nations commission headed by former Norwegian Prime Minister, Gro Brundtland. Intended to respond to a growing number of environmental concerns faced by the global community, it recognized the need for long-term strategies to manage natural resources. It says we must act collaboratively to protect the environment, while at the same time stimulating economic and social development.

British-born American political activist Thomas Paine wrote Rights of Man in 1791 in response to Reflections on the Revolution in France, Edmund Burke's attack on the French Revolution. Burke was wary of tearing down old institutions of government. But Paine argued that revolution is acceptable - in fact, necessary - when government ignores the rights of its people. Not surprisingly, Rights of Man proved very popular in the newly liberated United States, selling over 100,000 copies.
