Man is born free, and everywhere he is in chains. In The Social Contract, Rousseau explores the concept of freedom and the political structures that may enable people to acquire it. He argues that the sovereign power of a state lies not in any one ruler but in the will of the general population. Rousseau argues that the ideal state would be a direct democracy where executive decision making is carried out by citizens who meet in assembly, as they would in the ancient city-state of Athens.

The leviathan is the vast unity of the State. But how are unity, peace, and security to be attained? Hobbes’ answer is sovereignty, but the resurgence of interest today in Leviathan is due less to its answers than its methods: Hobbes sees politics as a science capable of the same axiomatic approach as geometry.

The English philosopher and physician John Locke (1632 - 1704) is widely regarded as one of the most influential of Enlightenment thinkers. His work had a significant effect on the development of epistemology and political philosophy. The Second Treatise on Civil Government places sovereignty in the hands of the people, as Locke's fundamental argument is that people are equal and invested with natural rights in a state of nature in which they live free from outside rule. 

Published in 1762, it had a profound impact on the approach to the education and upbringing of a child, through infancy, childhood, adolescence and into adulthood. This was partly fuelled by the format – for Rousseau presents before us the boy Emile, taking him through the various stages of life, and as Emile becomes a young man, introducing a female counterpart, Sophie. This device personalises what would otherwise be a more formal philosophical presentation.  

On the Social Contract's appeal and influence has been wide-ranging and continuous. It has been called an encomium to democracy and, at the same time, a blueprint for totalitarianism. Individualists, collectivists, anarchists, and socialists have all taken courage from Rousseau's controversial masterpiece.

From his perspective in Renaissance Italy, Machiavelli's aim in this classic work was to resolve conflict with the ruling prince, Lorenzo de Medici. Machiavelli based his insights on the way people really are rather than an ideal of how they should be. This is the world's most famous master plan for seizing and holding power. Astonishing in its candor The Prince even today remains a disturbingly realistic and prophetic work on what it takes to be a prince, a king, or a president.

In On the Genealogy of Morals, subtitled "A Polemic", Nietzsche furthers his pursuit of a clarity that is less tainted by imposed prejudices. He looks at the way attitudes towards 'morality' evolved and the way congenital ideas of morality were heavily colored by the Judaic and Christian traditions.

Thomas Paine published Common Sense in 1776, a time when America was a hotbed of revolution. The pamphlet, which called for America's political freedom, sold more than 150,000 copies in three months. Paine not only spurred his fellow Americans to action but soon came to symbolize the spirit of the Revolution itself. His persuasive pieces, written so elegantly, spoke to the hearts and minds of all those fighting for freedom from England.

The Republic poses questions that endure: What is justice? What form of community fosters the best possible life for human beings? What is the nature and destiny of the soul? What form of education provides the best leaders for a good republic? What are the various forms of poetry and the other arts, and which ones should be fostered and which ones should be discouraged? How does knowing differ from believing?

This classic of American literature, a dramatic autobiography of the early life of an American slave, was first published in 1845, when its author had just achieved his freedom. It is a story that shocked the world with its first-hand account of the horrors of slavery. The book was an incredible success. It sold over 30,000 copies and was an international best seller.

“The problem of the twentieth century is the problem of the color line,” writes Du Bois, in one of the most prophetic works in all of American literature. First published in 1903, this collection of 15 essays dared to describe the racism that prevailed at that time in America—and to demand an end to it. Du Bois’ writing draws on his early experiences, from teaching in the hills of Tennessee, to the death of his infant son, to his historic break with the conciliatory position of Booker T. Washington.

With the same suppleness, energy, and range of voices that won their translation of The Brothers Karamazov the PEN/Book-of-the-Month Club Prize, Pevear and Volokhonsky offer a brilliant translation of Dostoevsky's classic novel that presents a clear insight into this astounding psychological thriller. This audio edition of Crime and Punishment is expressively brought to life by Peter Batchelor.

Sir Francis Bacon's The New Atlantis is a utopian novel about a mythical land called Bensalem, where the inhabitants live happily with the sciences. In The New Atlantis, Bacon focuses on the duty of the state toward science, and his projections for state-sponsored research anticipate many advances in medicine and surgery, meteorology, and machinery. Although The New Atlantis is only a part of his plan for an ideal commonwealth, this work does represent Bacon's ideological beliefs.

This classic, definitive account of totalitarianism traces the emergence of modern racism as an "ideological weapon for imperialism", beginning with the rise of anti-Semitism in Europe in the 19th century and continuing through the New Imperialism period from 1884 to World War I.

John Locke and his works - particularly An Essay Concerning Human Understanding - are regularly and rightly presented as foundations for the Age of Enlightenment. His primary epistemological message - that the mind at birth is a blank sheet waiting to be filled by the experiences of the senses - complemented his primary political message: that human beings are free and equal and have the right to envision, create and direct the governments that rule them and the societies within which they live.
