Aristotle's Nicomachean Ethics, said to be dedicated to Aristotle's son, Nicomachus, is widely regarded as one of the most important works in the history of Western philosophy. Addressing the question of how men should best live, Aristotle's treatise is not a mere philosophical meditation on the subject, but a practical examination that aims to provide a guide for living out its recommendations.

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?

Aristotle was a Greek philosopher and polymath during the Classical period in Ancient Greece. His writings cover many subjects including physics, biology, zoology, metaphysics, logic, ethics, aesthetics, poetry, theatre, music, rhetoric, psychology, linguistics, economics, politics and government.

Aristotle’s Nicomachean Ethics and Eudemian Ethics represent, in many ways, the Western classical springboard for the systematic study and implementation of ethics, the optimum behaviour of the individual. (By contrast, Aristotle’s Politics concerns the optimum blueprint for the city-state.) It is in the hands of each individual, he argues in these books on personal ethics, to develop a character which bases a life on virtue, with positive but moderate habits.

Aristotle's Metaphysics was the first major study of the subject of metaphysics - in other words, an inquiry into 'first philosophy', or 'wisdom'. It differs from Physics which is concerned with the natural world: things which are subject to the laws of nature, things that move and change, are measurable. In Metaphysics, the study falls on 'being qua being' - being insofar as it is being; the causes and principles of being, the causes and principles of substances.

Aristotle’s Organon comprises six key essays on logic, initially collected by Theophrastus, his successor as head of the Peripatetic school, and given its final form by Andronicus some three centuries later. The six essays are: Categories, On Interpretation, Prior Analytics, Posterior Analytics, Topics and On Sophistical Refutations. One of the principal topics of Aristotle’s focus is syllogism, in which two premises (one major, one minor) lead to a conclusion. This features in Prior Analytics and On Interpretation.

The Summa Theologica, by Thomas Aquinas, is a fundamental text in Catholic doctrine, a compendium of theology that has been studied and debated since its first publication in the 13th century. Furthermore, it has been widely regarded as one of the classics of Western philosophy, not least because, perhaps for the first time in such a systematic manner, it set out to consider the views of non-Christian figures such as Aristotle, Boethius, Muslim writers including Averroes (Ibn Rushd) and Avicenna (Ibn Sina) and the Sephardic Jewish scholar Maimonides.

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 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.

‘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.

Human Action is the most important book on political economy you will ever own. It was (and remains) the most comprehensive, systematic, forthright, and powerful defense of the economics of liberty ever written. This is the Scholar's Edition: accept no substitute. You will treasure this volume. The Scholar's Edition is the original, unaltered treatise (originally published in 1949) that shaped a generation of Austrians and made possible the intellectual movement that is leading the global charge for free markets.

What does it mean to say that we live in a secular age? Almost everyone would agree that we - in the West, at least - largely do. And clearly the place of religion in our societies has changed profoundly in the last few centuries. In what will be a defining book for our time, Charles Taylor takes up the question of what these changes mean - of what, precisely, happens when a society in which it is virtually impossible not to believe in God becomes one in which faith, even for the staunchest believer, is only one human possibility among others.

Originally published anonymously, The Federalist Papers first appeared in 1787 as a series of letters to New York newspapers exhorting voters to ratify the proposed Constitution of the United States. Still hotly debated and open to often controversial interpretations, the arguments first presented here by three of America's greatest patriots and political theorists were created during a critical moment in our nation's history.

The first volume of Will Durant's Pulitzer Prize-winning series, Our Oriental Heritage: The Story of Civilization, Volume I chronicles the early history of Egypt, the Middle East, and Asia.
