John Stuart Mill (1808-1873) was a torchbearer for liberal thought in the 19th century, including liberty of the individual and freedom of speech, and he championed women's suffrage in Parliament. A remarkable man - he learned Greek aged three and at eight had read Herodotus, Xenophon and Plato - he campaigned all his life for a just society. These two essays are his key works.

Often considered the foundation of political liberalism, John Locke's Two Treatises of Government was first published anonymously in 1689, in the wake of England's Glorious Revolution. In The First Treatise of Government, Locke refutes the idea of divine monarchy, while The Second Treatise of Government articulates Locke's philosophy of government, which he based upon his theories of natural rights and the social contract.

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.

Immanuel Kant’s Critique of Pure Reason can lay claim to being the most important single work of modern philosophy, a work whose methodology, if not necessarily always its conclusions, has had a profound influence on almost all subsequent philosophical discourse. In this work Kant addresses, in a groundbreaking elucidation of the nature of reason, the age-old question of philosophy: “How do we know what we know?” and the limits of what it is that we can know with certainty.

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.

Credited as the Father of Liberalism and revered for his ground-breaking theories, John Locke left behind a legacy which has radically shaped political and philosophical thought for over 300 years. His writings continue to inspire and educate people to this day, from founding our central ideas of consciousness and knowledge to creating a framework for society which greatly influenced America’s founding fathers.

The foundation for all modern economic thought and political economy, The Wealth of Nations is the magnum opus of Scottish economist Adam Smith, who introduces the world to the very idea of economics and capitalism in the modern sense of the words.

Virtually all human societies were once organized tribally, yet over time most developed new political institutions which included a central state that could keep the peace and uniform laws that applied to all citizens. Some went on to create governments that were accountable to their constituents. We take these institutions for granted, but they are absent or are unable to perform in many of today’s developing countries—with often disastrous consequences for the rest of the world.

Galbraith's classic on the "economics of abundance" is, in the words of the New York Times, "a compelling challenge to conventional thought". With customary clarity, eloquence, and humor, Galbraith cuts to the heart of what economic security means (and doesn't mean) in today's world and lays bare the hazards of individual and societal complacence about economic inequity.

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 City of God is one of the most important works of Christian history and philosophy ever written. The writings of St. Augustine are as intriguing to the casual reader as it is to Christian researchers. St. Augustine's work provides insight into Western thought and the development of Western civilizations. The City of God provides the reader with an artful contrast between earthy cities and those in heaven as a representation of the eternal struggle between good and evil. The City of God was originally penned in the early 5th century as a response to the prevalent belief that Christianity was to blame for the fall of Rome. St. Augustine is known as one of the most influential Fathers of the Catholic Church. Born November 13, 354, Augustine would eventually be recognized as a Saint by the Catholic Church, the Eastern Christian Church, and the Anglican Communion.

Perhaps the most influential science book ever written, On the Origin of Species has continued to fascinate for more than a century after its initial publication. Its controversial theory that populations evolve and adapt through a process known as natural selection led to heated scientific, philosophical, and religious debate, revolutionizing every discipline in its wake. With its clear, concise, and surprisingly enjoyable prose, On the Origin of Species is both captivating and edifying.

This classic of Mormon literature is based on a series of theological lectures by Talmage, which were created for use in religious education. James E. Talmage was an English chemist and geologist, who moved to the United States and became a prominent figure in the Church of Jesus Christ of Latter-Day Saints. This book provides commentary and doctrinal references for each of Joseph Smith's Thirteen Articles of Faith that form the core beliefs of the LDS Church.

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?
