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.

Business scholars C. K. Prahalad and Gary Hamel base their 1990 argument for a strategy change on a comparison of case studies. They note that some corporations are adept at inventing new markets, quickly entering emerging markets, and shifting patterns of customer choice in established markets. The authors suggest that the ability to identify core competencies allows companies to develop new products quickly, and they challenge managers to emulate these best practices

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.

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.

Rachel Carson worked at the US Bureau of Fisheries for 15 years while developing a writing career at the same time. Her first book, 1941's Under the Sea Wind, became a best seller. But it was eclipsed by 1962's Silent Spring, one of the first books ever to highlight environmentalist issues. Carson focuses on the negative, widespread, and long-lasting effects of human activity on the environment, and illustrates this through one case study - the use of chemical pesticides in agriculture.

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.

James E. Lovelock says the Earth (Gaia) is a superorganism, made up of all living things, interacting with the air, the oceans, and the surface rocks of the planet. He suggests Gaia takes an active role in keeping the planet safe for life, with automatic feedback mechanisms making adjustments as needed. Lovelock describes feedback mechanisms that are widely accepted. It is the implication that Gaia is somehow self-aware that is controversial.

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.
