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.

Among the general public, Descartes is probably most famous for his pronouncement "I think, therefore I am." That statement first appeared in an earlier work, but he expands on it in Meditations as he considers the idea of the mind as a separate entity to the body - the "dualist" approach. Descartes also set out to dispel skepticism - the idea that one cannot truly know anything. Using his "methodological skepticism," he showed that by doubting everything, we can know some things beyond doubt.

First published in Germany in 1980, British historian Ian Kershaw's The "Hitler Myth" is recognized as one of the most important books ever written about Adolf Hitler and the Nazi State. Kershaw wanted to focus on what he called the "history of everyday life", and so investigated the attitude of the German public to Hitler at the time, rather than looking at the dictator from the perspective of those in positions of power. He was intrigued to find out how someone like Hitler could have become such a powerful figure.

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.

Richard Dawkins' 1976 investigation into the science of evolution has become an enormous success, selling over a million copies in 25 languages. Drawing on the work of renowned evolutionary scientists, Dawkins makes his argument about evolution by focusing on the gene itself. While others considered evolution to occur at the level of the individual or the group, here Dawkins sees the process of natural selection differently.

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.

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.

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.

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.

Sigmund Freud was born in 1856, in Vienna, Austria, and died in London in 1939, but his reputation as "the father of psychoanalysis" lives on. The theories he introduced in his masterwork, The Interpretation of Dreams, revolutionized the treatment of mental illness in the late 19th century. Based on his success in using new techniques he had developed with his patients, and on conclusions he drew from analyzing his own dreams, Freud said that dreams offered a window into the workings of the unconscious mind.

In his 1986 book War Without Mercy, American historian John Dower examines Japanese-American relations during World War II and investigates links between popular culture, stereotypes, and extreme violence. He argues that it was the concept of racism - used equally by both sides - that underpinned the military conflict and led to a particularly brutal war in the Pacific and East Asia.

Nineteenth-century American politician John C. Calhoun was unashamedly pro-slavery. So it may seem odd that A Disquisition on Government (1850), written in part to protect that practice, is so respected today. But South Carolina-born Calhoun was undoubtedly a great political thinker. Calhoun - who served his country as senator, vice president, secretary of war, and secretary of state - believed that "majority rule" inevitably led to abuse of power.

What is the past - and what can we really know about it? This is the big question that 20th-century French historian Lucien Febvre works his way through in 1942's The Problem of Unbelief. Relying on his own innovative technique championing "problem-based history", Febvre focuses specifically on 16th-century French writer François Rabelais to answer one controversial question: Was Rabelais, as historians had always agreed, really one of his country's first atheists?

Since it was first published in 1973, A Random Walk Down Wall Street has been a highly influential best seller. Burton G. Malkiel demolishes the idea that investment "experts" can predict stock price changes and thereby "beat the market." With all available information that could affect the value of a company's shares known almost instantly to all investors, Malkiel says, shares quickly find the price that reflects that information. This is known as the efficient market hypothesis.

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.

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.

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.
