Published in 1651, Leviathan is considered to be one of the most important works of political philosophy and a major contribution to the modern idea of central government. In the mid-17th century, England was going through a turbulent time of change and unrest, which likely shaped Hobbes' ideas on strong government. Thomas Hobbes established the social contract theory. He believed that self-government did not create the ideal state due to the human tendency to be self-serving, something he believed would eventually lead to chaos.

This book consists of two parts: the essay "The Idea of Public Reason Revisited" and "The Law of Peoples", a major reworking of a much shorter article by the same name. Taken together, they are the culmination of more than 50 years of reflection on liberalism and on some of the most pressing problems of our times.

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.

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.

From the moment of its publication in 1748, The Spirit of the Laws proved to be a controversial work provoking widespread interest. Within three years it had been translated into various European languages - and was swiftly added to the List of Prohibited Books by the Roman Catholic Church. It is a remarkable book, a potpourri of observations and comments ranging far and wide over the social activities of mankind and it exerted a great influence on political leaders in the following decades.

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.

‘It was a sweet finish after the bitter pills of floggings and bullets with which these same governments, just at that time, dosed the German working-class risings’. The Communist Manifesto is, perhaps surprisingly, a most engaging and accessible work, containing even the odd shaft of humour in this translation by Samuel Moore for the 1888 English edition.

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.

The Pleasure of Finding Things Out is a magnificent treasury of the best short works of Richard P. Feynman, from interviews and speeches to lectures and printed articles. A sweeping, wide-ranging collection, it presents an intimate and fascinating view of a life in science - a life like no other. From his ruminations on science in our culture to his Nobel Prize acceptance speech, this book will delight anyone interested in the world of ideas.

A classic work of military strategy, On War sets forth the theories and tactics of Carl von Clausewitz, a distinguished Prussian general who was notable for his roles in the French Revolutionary and Napoleonic Wars. The book covers a broad range of topics, including weapons, terrain, troops, and leadership, as well as the importance of defense over offence, the balance of power, and the subordination of war to politics. Praised for its timeless insights, Clausewitz’s treatise is often compared to the work of Machiavelli and Sun Tzu, and remains relevant to military leaders.

First published in 1859, John Stuart Mill's On Liberty is an exhaustive exploration of social and civic liberty, its limits, and its consequences. Mill's work is a classic of political liberalism that contains a rational justification of the freedom of the individual in opposition to the claims of the state.

A celebration of individuality, diversity, and nonconformity, On Liberty still makes a persuasive argument for what John Stuart Mill believed to be humankind’s essential liberties: the freedoms of speech, assembly, and the pursuit of pleasure, so long as one’s actions do not impede the liberty of another. These freedoms, he maintained, result in a far more successful society than one ruled by the tyranny of the majority. This treatise on personal liberty has inspired debate since its publication in 1859, and has provided the foundation for modern liberal political thought.

First published in 1936, Keynes’ ideas had evolved during the difficulties following World War 1 in Europe, and the US crash and the Depression of the 1920s-'30s and the misery of mass unemployment. He deplored the situation where a few individuals or companies stored massive wealth while vast numbers experienced poverty and insecurity (his alarm bells ring today!) and sought to promote initiatives where governments could intervene with social projects to keep money fluctuating.

An indictment of the American educational system criticizes the fact that the system has discarded the traditional goals of transmitting knowledge and fostering cognitive skills in favor of building self-esteem and promoting social harmony.

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.

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.

Thomas Hobbes lived through the Thirty Years War and Britain's civil wars, and the trauma of these events led to his great masterpiece of political thought. How could humankind rescue itself from life in the natural state, which was 'poor, nasty, brutish and short'? Vilified and scorned from the moment it was published, Leviathan was publicly burnt for sedition, but ever since it has exercised a unique fascination upon its readers, both for its ideas and its remarkable prose. Its concepts helped to drag Europe into a new world - one in which we still live today.

In the mid-17th century, England was going through a turbulent time of change and unrest, which likely shaped Hobbes' ideas on strong government. Thomas Hobbes established the social contract theory.

Continuing where Thus Spoke Zarathustra left off, Nietzsche's controversial work Beyond Good and Evil is one of the most influential philosophical texts of the 19th century and one of the most controversial works of ideology ever written. Attacking the notion of morality as nothing more than institutionalised weakness, Nietzsche criticises past philosophers for their unquestioning acceptance of moral precepts. Nietzsche tried to formulate what he called "the philosophy of the future".

Born out of the political turmoil of the English Civil War, Leviathan stands out as one of the most in influential political and philosophical texts of the 17th century. It argues for the restoration of the monarchy in light of the republic and calls for a commonwealth ruled by an authoritative, autocratic figure with absolute sovereignty. This would put an end to all controversy, war, and fear and establish peace via social contract.
