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.

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.

Albert Hourani's 1991 work, A History of the Arab Peoples, is unsurpassed as an overview of Arab history, from the rise of Islam to the late 20th century. Going far beyond the political history that had generally characterized previous examinations, Hourani integrates a wide range of scholarship to provide a deep analysis of social, cultural, and economic structures. His interest in the everyday lives of Arab people and his desire to understand what united - rather than divided - many different nationalities gives listeners a new and vital perspective on the region.

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.

The title of Norwegian-born historian Odd Arne Westad's 2005 work - The Global Cold War: Third World Interventions and the Making of Our Times - offers a window into his thesis. Between the end of World War II and the early 1990s, both the Soviet Union and the United States "intervened" (or "offered aid and support to") developing nations in Africa, Asia, and Latin America. In Westad's view, these interventions were more important than events in Europe, where most studies of the Cold War focus.

Written more than 2,000 years ago, this earliest surviving work on how to wage war successfully - and above all, rationally - argues that winning requires careful advance planning, better sources of information than your opponent, and a strategy that's flexible enough to adapt to changing conditions. Sun Tzu concludes that in the end, a decision not to take military action can be every bit as sensible and effective as being able to triumph on the battlefield.

Defining liberty as freedom from interference by state power or popular moral opinion, Mill justifies the individual's right to this liberty by focusing on the role self-development plays in human well-being. His vision of individual rights extends to include freedom of thought and emotion and the freedom to act together with others. Society should protect the development of individuality to aid both social progress and innovation.

Though written around 1513, more than 500 years ago, Italian diplomat Niccolò Machiavelli's The Prince is still both widely listened to and very influential. Listeners turn to it for its direct advice on the question of how to attain - and retain - power. Machiavelli's answer, in brief: Use any means necessary to make sure the state survives.

Iranian American writer and scholar Hamid Dabashi wrote Iran: A People Interrupted amid the political fallout following the 9/11 terrorist attacks on New York - his adopted city - in 2001. As US President George W. Bush declared a "war on terror" and named Iran as part of an "axis of evil" that supported terrorism, Dabashi offered an insider's insight into the Iranian psyche.

Having witnessed some negative effects of democratic revolutions in his native France, Tocqueville visited America in 1831 to see what a functioning republic looked like. His main concerns were that democracy could make people too dependent on the state and that minority voices might not be heard - a problem he termed "the Tyranny of the Majority". By examining America thoroughly, Tocqueville hoped to show how a democratic system could avoid these pitfalls.

In his 1807 work Phenomenology of Spirit, G. W. F. Hegel introduced the world to his philosophical system. His most influential work - and the culmination of the German Idealist movement begun in the late 18th century as a response to the works of Immanuel Kant - the book remains one of the undisputed classics of Western thought.

American sociologist Jack A. Goldstone examines the causes of revolutions and uprisings in the period between 1500 and 1800. Investigating cases in both Europe and Asia, the conclusions he reaches are surprising. Many thinkers had previously believed that Europe's distinctive history - and particularly the rise of capitalism - had created the specific revolutions and political changes that launched the continent on a path to global supremacy. Goldstone says this is wrong, and that European and Asian states were, in fact, all experiencing similar developments.

English historian Christopher Hill turned thinking about the English Civil Wars (1642-51) on its head when he published The World Turned Upside Down in 1972. Instead of focusing on power struggles in the upper echelons of English society - on the battle between the monarchy and would-be republicans - Hill looked to develop "history from below", investigating the lives of ordinary people, the way they saw society, and their political hopes for the future.

World Order draws together Henry Kissinger's thinking on how we make sense of the world politically. Kissinger identifies four principal competing methods by which order has been and is still sought. Those four conceptions are European, Chinese, Islamic, and American. None of these has been accepted as dominant. Kissinger asks whether a new, universal world order can be developed today.

In the century before the Black Death swept across the developed world, economic relations flourished between Europe, the Middle East, and Asia. Before European Hegemony looks at this period. Without any dominant power, the world's economy revolved around eight interlocking sub-systems, with the major world cities and towns playing a crucial role in the system as a whole. But as economic activity spread across borders, so did the Black Death.

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 1974, Roll Jordan, Roll is American historian Eugene Genovese's epic study of slavery in the United States in the late 18th and 19th centuries. It provides a nuanced understanding of the relationship between master and slave. Slave owners saw it as their duty to limit slaves' freedoms for their own good, as a father might deal with his children. But Genovese looked beyond this notion of paternalism to suggest the relationship was more complex.
