In a career spanning 60 years, Sir Karl Popper has made some of the most important contributions to the 20th century discussion of science and rationality. The Myth of the Framework is a collection of some of Popper's most important material on this subject.

All Life is Problem Solving is a stimulating and provocative selection of Popper's writings on his main preoccupations during the last twenty-five years of his life. This collection illuminates Popper's process of working out key formulations in his theory of science, and indicates his view of the state of the world at the end of the Cold War and after the collapse of communism.

Conjectures and Refutations is one of Karl Popper’s most wide-ranging and popular works, notable not only for its acute insights into the way scientific knowledge grows, but also for applying those insights to politics and to history. It provides one of the clearest and most accessible statements of the fundamental idea that guided his work: not only our knowledge but our aims and our standards grow through an unending process of trial and error.

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.

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.’

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.

The brilliantly original French thinker who died in 1984 gives an analysis of how the ancient Greeks perceived sexuality. Throughout The Use of Pleasure Foucault analyzes an irresistible array of ancient Greek texts on eroticism as he tries to answer basic questions: How in the West did sexual experience become a moral issue? And why were other appetites of the body, such as hunger, and collective concerns, such as civic duty, not subjected to the numberless rules and regulations and judgments that have defined, if not confined, sexual behavior?

In this valedictory volume, Yale professor Harold Bloom — who for more than half a century was regarded as America's most daringly original and controversial literary critic — gives us his only book devoted entirely to the art of the novel. With his hallmark percipience, remarkable scholarship, and extraordinary devotion to sublimity, Bloom offers meditations on 48 essential works spanning the Western canon.

Throughout the twentieth century, The Protestant Ethic and the Spirit of Capitalism was regarded as an important sociological and economic text, continuing into the twenty-first century, when extreme capitalism has continued to come under fire. Weber's work provided a history, from where the profit motive could be ethically justified. Max Weber combined his interests in sociology, political economy and history to give perspective to his analysis. Concentrating principally on the experience of the West, he returned to the time when religion, its concepts and practice, dominated society.

The Russian Revolution of 1917 was one of the most cataclysmic events in world history, profoundly shaping politics, international relations, social patterns, economics and science in the century that followed. It created long-lasting aftershocks which travelled far beyond its geographical borders. How did it happen? What were the sequence of events that led, following the shocking upheaval of the old Romanov order, to a fierce and violent rivalry between a variety of revolutionary factions and the ultimate victory of the Bolsheviks?

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'.

Henri Bergson (1859-1941) was the leading French philosopher of the first half of the 20th century. Near the end of his life when he was forced to register with the police in Nazi occupied France he wrote: ‘Academic. Philosopher. Nobel prize winner. Jew.’ Time and Free Will, his doctoral thesis, was published as a book in 1889 and attacks and rejects the mechanistic view of causality described in Kant’s version of space and time and proceeds to attempt to define free-will and consciousness by separating space and time.

A good book may have the power to change the way we see the world, but a great book actually becomes part of our daily consciousness, pervading our thinking to the point that we take it for granted, and we forget how provocative and challenging its ideas once were - and still are. The Structure of Scientific Revolutions is that kind of book.

Few modern voices have had as profound an impact on the black identity and critical race theory as Frantz Fanon, and Black Skin, White Masks represents some of his most important work. Fanon's masterwork is now available in a new translation that updates its language for a new generation of listeners. A major influence on civil rights, anti-colonial, and black consciousness movements around the world, Black Skin, White Masks is the unsurpassed study of the black psyche in a white world.

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.

In a career spanning 60 years, Sir Karl Popper has made some of the most important contributions to the 20th century discussion of science and rationality. The Myth of the Framework is a collection of some of Popper's most important material on this subject.

Upon its first English publication in 1959, Popper's The Logic of Scientific Discovery revolutionized thinking about the scientific method. Largely an exploration of the demarcation problem, or what distinguishes science from non-science, Popper introduced and defended his concept of falsifability -- that scientific systems are ones open to empirical disconfirmation -- against the prevailing views of his day.

An immediate sensation when it was first published in two volumes in 1945, Popper's monumental achievement has attained legendary status on both the Left and Right and is credited with inspiring anticommunist dissidents during the Cold War. Arguing that the spirit of free, critical inquiry that governs scientific investigation should also apply to politics, Popper traces the roots of an opposite, authoritarian tendency to a tradition represented by Plato, Marx, and Hegel.

In a letter of 1932, Karl Popper described Die beiden Grundprobleme der Erkenntnistheorie–The Two Fundamental Problems of the Theory of Knowledge–as ‘…a child of crises, above all of …the crisis of physics.' The two fundamental problems of knowledge that lie at the center of the book are the problem of induction, that although we are able to observe only a limited number of particular events, science nevertheless advances unrestricted universal statements; and the problem of demarcation, which asks for a separating line between empirical science and non-science.
