Born in 1933, Philip Zimbardo is a renowned and controversial American social psychologist who is fascinated by why people can sometimes behave in awful ways. Some psychologists believe people who commit cruelty are innately evil. Zimbardo disagrees. In his 2007 book, The Lucifer Effect, he argued that it is the power of situations around us that can cause otherwise good people to commit "evil", citing many historical examples to illustrate his point.

In the 1960s, British historian Jonathan Riley-Smith first began studying the knightly orders of the Middle Ages that formed after the First Crusade. By the late 1970s, he had begun writing books from a "revisionist" point of view, challenging the common belief that the Crusades were motivated by fanaticism, and were designed to plunder the Holy Lands. To an extent, Riley-Smith's 1986 book The First Crusade and the Idea of Crusading overturned this previously held view.

In Citizen and Subject, Ugandan academic and author Mahmood Mamdani challenges dominant views about the crisis of postcolonial Africa. Many studies emphasize that the problems the continent faces are homegrown - the consequence of poor government, widespread corruption, and other local factors. Citizen and Subject challenged these ideas. It argues that the current crisis has come about because of the institutional legacy of colonialism.

Based around a Marxist understanding of class struggle, Lefebvre sees the revolution not just as a political crisis, but also as an assault on inherited privilege and the social hierarchy. Ultimately, it succeeded because people at every level of society - from nobles and the elite bourgeois to peasants and the urban masses - found the will to defy the crown. Lefebvre's book was later interpreted by some as simplistic and overly partisan, designed as a rallying call to his fellow countrymen.

In her 1958 article "Modern Moral Philosophy", British philosopher Elizabeth (G. E. M.) Anscombe does nothing less than challenge the very foundations of moral philosophy, the discipline that tries to understand right and wrong action. The article sets out three main ideas. First, that moral philosophy should not be explored until a philosophy of psychology is already in place. Second, that philosophers who do not believe in God should not use ideas about "obligation" and "duty".

First available in 1689, John Locke's Two Treatises of Government is considered one of the most important works ever written on the foundations of government. Published anonymously, it argues against the popular idea at the time that monarchs have a God-given right to rule. Instead Locke proposes that sovereignty - supreme authority - ultimately resides with the people.

How many books can claim to be so influential as to inspire the development of a whole school of thought? The ancient Greek philosopher Aristotle's Metaphysics did exactly that, laying the foundations for a new branch of philosophy - metaphysics - concerned with the cause and nature of being.

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.

US psychologist Abraham Maslow's 1943 essay "A Theory of Human Motivation" established his idea of humanistic psychology as a "third force" in the field. He outlined a new approach to understanding the mind, saying humans are motivated by their need to satisfy a series of hierarchical needs, starting with the most essential first. He thought it important for the advancement of psychology to identify, group, and rank them in terms of priority.

David Hume's book tackling the subject of belief in God is among the most influential in Western philosophy. Published in 1779, three years after Hume's death, without featuring the author's name, the book was deeply controversial in its day. It is now considered a masterpiece and Hume is regarded as one of the greatest philosophers writing in English.

Under the title "Civil Disobedience", American author Henry David Thoreau's essay was originally published in 1866, four years after his death in 1862. It is based on a lecture, "Resistance to Civil Government", that Thoreau gave many years earlier, in 1848. "Civil Disobedience" asked when an individual should actively oppose a government and its justice system. Thoreau's answer was that opposition was legitimate whenever government actions or institutions were unacceptable to an individual's conscience.

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.

C. S. Lewis may be most famous for his fiction, including children's books like the Chronicles of Narnia series. But in his 1952 book Mere Christianity - originally printed as three separate pamphlets in 1942, 1943, and 1944 - this eclectic and learned man documents his complex journey from atheism to faith.

How do we know what knowledge is? In his 1963 article, "Is Justified True Belief Knowledge?", American philosopher Edmund Gettier radically challenged the accepted definition of knowledge itself. Greek philosopher Plato, discussing knowledge well over 2,000 years ago, defined it as "justified true belief". But in two ingenious cases, Gettier demonstrates that somebody's justified belief can be true because of nothing more than luck.

An extraordinarily ambitious work, Republic has made important contributions to many branches of modern philosophy. The work unfolds as a series of conversations in which participants set out a number of different theories of justice, and then imagine how these theories might become reality within the political structure of a city. In examining justice, Plato investigates an enormous range of questions in the areas of ethics, politics, and even the nature of existence itself.

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.

A work that had a huge influence on great thinkers including celebrated German philosopher Immanuel Kant, An Enquiry is Hume's examination of how we obtain information and form beliefs. He argues that we mainly gain knowledge through our senses, a theory known as empiricism. But while the impressions from our senses are key to our beliefs about the world, Hume argues that reason and facts play only a limited part.

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.

Why has gender inequality persisted for so long without revolutionary change? That's the central question Joan Wallach Scott poses in her 1998 collection of essays, Gender and the Politics of History. Scott notes that obvious economic, social, and class inequalities have produced large-scale social change, but uncovering the reality of gender inequality has not done the same.
