Do people always act rationally and in their own best interests? US economist Richard Thaler and legal scholar Cass Sunstein did not believe so, and were convinced that psychological factors often stopped people from making the best decisions. Their 2008 work Nudge: Improving Decisions About Health, Wealth and Happiness argues that governments should "nudge" citizens to make better choices in all sorts of areas, from eating habits, to health, to financial planning.

Before Bernard Bailyn published The Ideological Origins of the American Revolution in 1967, it was generally believed that the Revolution was driven both by social conflict between colonial settlers and the ruling British government, and by differences between classes in American society. Bailyn had a different view. He said that it was radical ideas that fired the American Revolution, and that the Revolution was above all else an ideological, constitutional, and political struggle.

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.

In The Age of Revolution, renowned British Marxist historian Eric Hobsbawm focuses on the historical period from the end of the 18th century to the middle of the 19th. He concludes that the "dual revolutions" of the time - the French Revolution and the British Industrial Revolution - changed the way the whole world thought about politics and power, and fundamentally shaped the modern era.

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.

The Problem of Slavery in the Age of Revolution, 1770-1823 offers a thorough account of the emergence of the antislavery movement in Britain and the United States. But what makes the work unique is the way it explores and unpicks the complex relationships between changes in our understanding of what is moral, the impact of political action, and its effect on social change.

One of the most influential works of political theory ever written, The Federalist Papers collects 85 essays from 1787 and 1788, when the United States was a new country looking to find its way politically. Thomas Jefferson, author of the country's Declaration of Independence and a future US president, called the work "the best commentary on the principles of government which ever was written".

In his best-selling 2013 book, Capital in the Twenty-First Century, Piketty takes issue with the idea that, despite the odd bump along the way (not least the 2007-08 global financial crisis), inequality tends to decline as capitalism matures. Piketty spent 15 years building an unparalleled database on wealth and income in France, the United States, and a number of other countries. He uses this data to argue that the opposite is true. Capitalism's natural tendency is, he says, to move toward ever-greater inequality.

Its arguments would go on to shape global economics and influence world leaders in the late 20th century, but Capitalism and Freedom was largely ignored when it was first published in 1962. The first work written for the general public by American economist Milton Friedman, the book argues that a free market with little government interference is the best way to run society.

"Common Sense" was published in 1776, at a time when America, then a colony of Great Britain, was teetering on the brink of war. It was an immediate success, a best seller, and was credited with galvanizing the people of America and George Washington's army. Paine's approach followed a path blazed by earlier thinkers such as John Locke and Thomas Hobbes, though he radicalized both their positions. For Paine, British rule in America amounted to little more than tyranny.

A winner of the 1992 Bancroft Prize, Nature's Metropolis broke new ground in the burgeoning field of environmental history, while also adding weight to both urban and Western history. Before its publication in 1991, historians generally treated urban and rural areas as distinct from one another, each following separate lines of development and maturity. Using Chicago and its surrounding areas as a model, Cronon's book looks to disprove this idea.

In Philosophical Investigations, the Austrian philosopher Ludwig Wittgenstein presents a radical approach to problems in the philosophy of language and the philosophy of mind. In fact, he sets out a radically new conception of philosophy itself. Published in 1953, two years after Wittgenstein's death, many still consider it one of the finest works of 20th century philosophy.

Mahbub ul Haq died in 1998, three years after the publication of his important work, Reflections on Human Development. The book appeared at the end of Haq's impressive career in international development and described his revolutionary contribution to the discipline. In it, Haq argues that the goal of any society should be to improve the lives of its citizens, therefore economic development should support that aim.

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 the 1960s, researchers into human memory began to understand memory as operating under two systems. The first was a short-term system handling information for mere seconds. The second was a long-term system capable of managing information indefinitely. They also discovered, however, that short-term memory was not simply a filing cabinet, but was actively working on cognitive - or mental - tasks. This is how the phrase "working memory" developed.

History of the Peloponnesian War was the first major work of political inquiry that did not relate events to divine influences. It introduced instead a critical method of looking to the facts of human actions as the basis of our understanding - a method that continues to be used today, more than two millennia later. Many of the most important political thinkers in the Western tradition cite Thucydides as an influence, and major figures including Thomas Hobbes, David Hume, and Friedrich Nietzsche have praised his writing.

Geneva-born thinker Jean-Jacques Rousseau's famous work of political philosophy from 1762 is based on a give-and-take theory of the relation between individual freedom and social order: the social contract that gives the work its name. Rousseau thinks about the issue by starting with what is known as the state of nature, a lawless condition where people are free to do what they like, governed only by their own instinctive sense of justice. People are free, but they are also vulnerable to chaos.

More than two centuries after its initial publication in 1781, Immanuel Kant's Critique of Pure Reason remains perhaps the most influential text in modern philosophy. Kant himself claimed his work as a revolutionary document and insisted that it changed the discipline of philosophy as thoroughly as Copernicus had changed astronomy 300 years earlier, when he said the Earth revolved around the sun and not the other way round.

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.

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.
