Frantz Fanon's Black Skin, White Masks offers a radical analysis of the psychological effects of colonization on the colonized. Born in 1925 on the island of Martinique - at the time a French colony - Fanon witnessed firsthand the abuses of white colonizers and the system's effects on his country. His revulsion was only confirmed later in life when he worked as a psychiatrist in Algeria, another French colony. Fanon's work played a pivotal role in the civil rights movements of the 1960s and was later taken up by scholars of postcolonialist studies.

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.

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.

What might society look like if we were brave enough to emerge fully from the shadow of the Christian God? The German philosopher Friedrich Nietzsche explores this intriguing question in his 1886 work, Beyond Good and Evil. Going further, Nietzsche then asks of his "philosophers of the future" that they take on the challenge of supplying humanity with new ideals to live by.

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.
