Religion is at the heart of man’s societies. ‘For a long time,’ Durkheim writes early on in his book, ‘it has been known that the first systems of representations with which men have pictured to themselves the world and themselves were of religious origin.’ Durkheim decided to examine how and why this phenomenon functioned and evolved - by looking specifically at simple societies and their religions, rather than at religions in more complex or developed societies.

Called the "fifth-most important sociological book of the 20th century" by the International Sociological Association, this groundbreaking study of knowledge introduces the concept of "social construction" into the social sciences for the first time. In it, Berger and Luckmann reformulate the task of the sociological subdiscipline that, since Max Scheler, has been known as the sociology of knowledge.

Philosophical Investigations was published in 1953, two years after the death of its author. In the preface written in Cambridge in 1945 where he was professor of philosophy he states: ‘Four years ago I had occasion to re-read my first book (the Tractatus Logico-Philosophicus) and to explain its ideas to someone. It suddenly seemed to me that I should publish those old thoughts and the new ones together: that the latter could be seen in the right light only by contrast with and against the background of my old way of thinking.’

Perhaps one of the most revolutionary works of philosophy ever presented, The Phenomenology of Spirit is Hegel's 1807 work that is in numerous ways extraordinary. A myriad of topics are discussed, and explained in such a harmoniously complex way that the method has been termed Hegelian dialectic. Ultimately, the work as a whole is a remarkable study of the mind's growth from its direct awareness to scientific philosophy, proving to be a difficult yet highly influential and enduring work.

Both a history and an examination of human thought and behavior spanning three thousand years, On Politics thrillingly traces the origins of political philosophy from the ancient Greeks to Machiavelli in Book I and from Hobbes to the present age in Book II. Whether examining Lord Acton's dictum that "absolute power corrupts absolutely" or explicating John Stuart Mill's contention that it is "better to be a human dissatisfied than a pig satisfied," Alan Ryan evokes the lives and minds of our greatest thinkers in a way that makes hearing about them a transcendent experience.

Throughout history philosophers have sought to define, understand, and delineate concepts important to human well-being. One such concept is "knowledge." Many philosophers believed that absolute, certain knowledge, is possible—that the physical world and ideas formulated about it could be given solid foundation unaffected by the varieties of mere opinion.

Francis Bacon (1561-1626), 1st Viscount St Albans, Attorney General and then Lord Chancellor of England, was an immensely learned, clever and ambitious man, with considerable political influence. However, he was also a philosopher with a wide interest in science, medicine and the classification of knowledge. Throughout his life he wrote a series of essays - following the manner set particularly by Montaigne, though extending back to Aristotle and others - the first 10 of which appeared in 1597.

Sigmund Freud (1856-1939) is remembered as the father of psychoanalysis. Civilization and Its Discontents (1930) is one of his key works, written three decades after his seminal book The Interpretation of Dreams. In it he considers the conflict between the needs of the individual acting both egotistically and altruistically in the pursuit of happiness and the myriad demands of civilised society and the ensuing tensions this clash of needs and demands generates.

Ever since its first publication in 1992, The End of History and the Last Man has provoked controversy and debate. Francis Fukuyama's prescient analysis of religious fundamentalism, politics, scientific progress, ethical codes, and war is as essential for a world fighting fundamentalist terrorists as it was for the end of the Cold War. Now updated with a new afterword, The End of History and the Last Man is a modern classic.

The front cover of the second edition of Language, Truth and Logic carried this statement in capital letters: ‘THE CLASSIC TEXT WHICH FOUNDED LOGICAL POSITIVISM - AND MODERN BRITISH PHILOSOPHY.’ It was a bold statement, but the book, first published in 1936 when A. J. Ayer was just 25 and a lecturer on philosophy at Christ Church, Oxford, drew unstinting praise from leading figures in the field, including Bertrand Russell.

This recording contains four important and related works by Heidegger: 'What Is Philosophy', 'What Is Metaphysics', 'On the Essence of Truth' and 'The Question of Being'.

Jacques Ellul’s The Technological Society has become a classic in its field, laying the groundwork for all other studies of technology and society that have followed. Ellul offers a penetrating analysis of our technological civilization, showing how technology - which began innocuously enough as a servant of humankind - threatens to overthrow humanity itself in its ongoing creation of an environment that meets its own ends. No conversation about the dangers of technology and its unavoidable effects on society can begin without a careful listening of this book.

From the perspective of an unbeliever, Fear and Trembling explores the paradox of faith, the nature of Christianity, and the complexity of human emotion. Kierkegaard examines the biblical story of Abraham, who was instructed to sacrifice his son Isaac, and forces us to consider Abraham's state of mind. What drove Abraham, and what made him carry out such an absurd and extreme request from God? Kierkegaard argues that Abraham's agreement to sacrifice Isaac, and his suspension of reason, elevated him to the highest level of faith.

First published in 1930, Civilization and Its Discontents is one of the most influential works of pioneering psychologist Sigmund Freud. Focusing on the tension between the primitive drives of the individual and the demands of civilization for order and conformity, Freud draws upon his psychoanalytic theories to explain the fundamental structures, conflicts, and consequences of society.

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.

Max Weber's best-known and most controversial work, The Protestant Ethic and the Spirit of Capitalism, first published in 1904, remains to this day powerful and fascinating. Weber's highly accessible style is just one of many reasons for his continuing popularity. The book contends that the Protestant ethic made possible and encouraged the development of capitalism in the West.

When it appeared in 1670, Baruch Spinoza’s Theological-Political Treatise was denounced as the most dangerous book ever published. In A Book Forged in Hell, Steven Nadler tells the fascinating story of this extraordinary book: its radical claims and their background in the philosophical, religious, and political tensions of the Dutch Golden Age, as well as the vitriolic reaction these ideas inspired.

This sharp commentary on the rise and current decline of Western Civilization touches on historical moments - including the building of early universities in the Middle Ages and the American Revolution - and figures - including Augustine, Acquinas, Edmund Burke, and Adam Smith - that exemplify the faith-reason synthesis at the heart of Western Civilization, as well as the modern villains that threaten to destroy it.

Forged during the tumultuous but triumphant postwar years when America came of age as a world power, The Irony of American History is more relevant now than ever before. Cited by politicians as diverse as Hillary Clinton and John McCain, Niebuhr's masterpiece on the incongruity between personal ideals and political reality is both an indictment of American moral complacency and a warning against the arrogance of virtue.

James V. Schall is a treasure of the Catholic intellectual tradition. A prolific author and essayist, Schall readily connects with his readers on sundry topics from war to friendship, philosophy, politics, and to ordinary everyday living. In his newest work, The Mind That Is Catholic, he presents a retrospective collection of his academic and literary essays written in the past 50 years.

"The fox knows many things, but the hedgehog knows one big thing." This ancient Greek aphorism, preserved in a fragment from the poet Archilochus, describes the central thesis of Isaiah Berlin's masterly essay on Leo Tolstoy and the philosophy of history, the subject of the epilogue to War and Peace. Although there have been many interpretations of the adage, Berlin uses it to mark a fundamental distinction between human beings who are fascinated by the infinite variety of things and those who relate everything to a central, all-embracing system.

Like F.A. Hayek, Ludwig von Mises moved beyond economics in his later years to address questions regarding the foundation of all social science. But unlike Hayek's attempts, Mises' writings on these matters have received less attention than they deserve. Theory and History, writes Rothbard in his introduction, "remains by far the most neglected masterwork of Mises". Here Mises defends his all-important idea of methodological dualism: one approach to the hard sciences and another for the social sciences.

At a time when popular atheism books are talking about the irrationality of believing in God, Willard makes a rigorous intellectual case for why it makes sense to believe in God and in Jesus, the Son.

lf a man cannot stand freedom, he will probably turn fascist. This, in the fewest possible words, is the essential argument in this modem classic, Escape from Freedom. The author, Erich Fromm, is a distinguished psychologist, late of Berlin and Heidelberg, now of New York City.

In this new essay collection she trains her incisive mind on our modern political climate and the mysteries of faith.
