First published in 1651, Leviathan drove important discussions about where kings get their authority to rule and what those kings must, in turn, do for their people. This is known as the "social contract". Thomas Hobbes wrote the book while exiled from his native England following the English Civil War that unseated King Charles I. In the face of England's radical - if temporary - rejection of its monarchy, Hobbes wanted to explain why it was important to have a strong central government, which in his time meant having a sovereign at its head.

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.

Arguing first that what might be termed a morally good action is one that increases the general sum of happiness in the world, Mill then says that general principles of justice should be based on this idea. Therefore, in life, there is no conflict between what is just and what is morally right. Mill published Utilitarianism toward the end of a lifetime spent as a moral philosopher, political activist, and social reformer.

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.

Clifford Geertz's first collection of essays, The Interpretation of Cultures (1973), made him a leading voice of anthropology's "symbolic" movement, which believed scholars should read the signs and symbols of a culture from the perspective of its natives. Geertz's approach helped anthropology reinvent itself as a scientific discipline that is still relevant today, making him - in the words of one critic - "a true giant of social and cultural theory."

Western thinking about the Middle and Far East has been distorted by stereotype and inaccuracy. This argument lies at the center of Palestinian-American literary theorist Edward Said's groundbreaking book, Orientalism. Originally published in 1978, it cemented Said's reputation as the father of postcolonial studies.

Linguistic structuralism studies the meaning of language based not just on definitions, but also on the relationships of words and sounds to each other. Lévi-Strauss's insight was to see that this concept of structuralism in linguistics could be applied to anthropology as well. He saw that while some cultures are very different from others, they all seem to have certain internal structural relationships in common. By tracing these structures across cultures, he tried to answer nothing less than the eternal question: "What is man?"

Sociologist Émile Durkheim's 1897 work On Suicide is a powerful evidence-based study of why people take their own lives. In the late 19th century it was generally accepted that each suicide was an individual phenomenon, caused by such personal factors as grief, loss, and financial problems. But Durkheim felt there were patterns in suicide rates, and believed that a more likely cause of suicide lay in the individual's relationship to society.

Published in 1974 in the journal Science, the article Judgment Under Uncertainty had a profound impact across the social sciences. Two relatively young Israeli psychologists were challenging the leading ideas about human thought. For decades, social scientists had used a mythical figure to describe how humans make decisions: homo economicus. Homo economicus was logical and conscientious.

Politics as a Vocation examines what makes good political leaders and explores the effects of political action on modern societies. On one level it summarizes the political scholarship of one of the founding fathers of social science. On another it reflects a leading German academic and political activist's practical concerns about the future at a time of great volatility following defeat in World War I.
