Martin Heidegger (1889-1976) is probably the most divisive philosopher of the twentieth century: Viewed by some as a charlatan and by others as a leader and central figure of modern philosophy. Michael Inwood's lucid introduction to Heidegger's thought focuses on his most important work, "Being and Time," and its major themes of existence in the world, inauthenticity, guilt, destiny, truth, and the nature of time.

Hegel is regarded as one of the most influential figures on modern political and intellectual development. After painting Hegel's life and times in broad strokes, Peter Singer goes on to tackle some of the more challenging aspects of Hegel's philosophy. Offering a broad discussion of Hegel's ideas and an account of his major works, Singer explains what have often been considered abstruse and obscure ideas in a clear and inviting manner.

Foucault is one of those rare philosophers who has become a cult figure. Born in 1926 in France, over the course of his life he dabbled in drugs, politics, and the Paris SM scene, all whilst striving to understand the deep concepts of identity, knowledge, and power. From aesthetics to the penal system; from madness and civilization to avant-garde literature, Foucault was happy to reject old models of thinking and replace them with versions that are still widely debated today.

With his well-known idiosyncrasies and aphoristic style, Friedrich Nietzsche is always bracing and provocative, and temptingly easy to dip into. Michael Tanner's introduction to the philosopher's life and work examines the numerous ambiguities inherent in his writings and explodes many of the misconceptions that have grown in the hundred years since Nietzsche wrote "do not, above all, confound me with what I am not!"

Kant is arguably the most influential modern philosopher, but also one of the most difficult. Roger Scruton tackles his exceptionally complex subject with a strong hand, exploring the background to Kant's work and showing why the Critique of Pure Reason has proved so enduring.

Philosophy for busy people. Listen to this succinct account of the philosophy of Wittgenstein in just one hour. Ludwig Wittgenstein saw himself as ‘the last philosopher’. In his view, philosophy in the traditional sense was finished. A superb logician, Wittgenstein distrusted language and sought to solve the problems of philosophy by reducing them to the purest form of logic. Everything else - metaphysics, aesthetics, ethics, finally even philosophy itself - was excluded.

Friedrich Nietzsche's work blasted the foundation of Western thinking. The death of God, the Übermensch and the slave morality permeate our culture, high and low, and yet he is one of history's most misunderstood philosophers. Nietzsche himself thought that all philosophy was autobiographical, and in this myth-shattering book Sue Prideaux brings listeners into the world of a brilliant, eccentric and deeply troubled man, illuminating the events and people that shaped his life and work.

In this Very Short Introduction Christopher Butler challenges and explores the key ideas of postmodernists, and their engagement with theory, literature, the visual arts, film, architecture, and music. He treats artists, intellectuals, critics, and social scientists 'as if they were all members of a loosely constituted and quarrelsome political party' - a party which includes such members as Cindy Sherman, Salman Rushdie, Jacques Derrida, Walter Abish, and Richard Rorty - creating a vastly entertaining framework in which to unravel the mysteries of the 'postmodern condition', from the politicizing of museum culture to the cult of the politically correct.

One of the two major philosophical traditions of the 20th century was linguistic analysis, derived largely from Wittgenstein. The other, diametrically opposed, came from Heidegger, and its fundamental question was: ‘What is the meaning of existence?’ For Heidegger, this was not a query that could simply be ‘analysed away’ - it was beyond the reach of logic or reason. This was the primary ‘given’ of every individual life. To confront it, Heidegger needed to develop an entirely new form of philosophy. Here is a concise, expert account of Heidegger’s life and philosophical ideas that is entertainingly written and easy to understand.

Philosophy for busy people. Listen to a succinct account of the philosophy of Kierkegaard in just one hour.Although Kierkegaard was not a philosopher in the academic sense, he produced what many people expect of philosophy. He didn’t write about the world, he wrote about life – how we live and how we choose to live, particularly focussing on the individual and the notion of his (or her) existence.

What is life? What is my place in it? What choices do these questions obligate me to make? More than a half-century after it burst upon the intellectual scene - with roots that extend to the mid-19th century - Existentialism's quest to answer these most fundamental questions of individual responsibility, morality, and personal freedom, life has continued to exert a profound attraction.

Philosophy for busy people. Listen to a succinct account of the philosophy of Aquinas in just one hour. Aquinas' influence stretches far across the western world; much modern philosophy has been conceived as either a reaction against, or in accordance with, his original ideas. This audiobook showcases an account of Thomas Aquinas’s life and philosophical ideas - entertainingly written and is above all easy listening. Also included are selections from Thomas Aquinas' work.

Penguin presents the audiobook edition of Enlightenment Now by Steven Pinker, read by Arthur Morey. Is modernity really failing? Or have we failed to appreciate progress and the ideals that make it possible? If you follow the headlines, the world in the 21st century appears to be sinking into chaos, hatred and irrationality. Yet, as Steven Pinker shows, if you follow the trendlines, you discover that our lives have become longer, healthier, safer and more prosperous - not just in the West but worldwide.

Philosophy for busy people. Listen to a succinct account of the philosophy of Hegel in just one hour. With Hegel philosophy became very difficult indeed – even the great man himself conceded that ‘only one man understands me, and even he does not.’ His dialectical method produced the most grandiose metaphysical system known to humanity, and included absolutely everything, its most vital element being the dialectic of the thesis, antithesis and synthesis.

Critical Theory emerged in the 1920s from the work of the Frankfurt School, the circle of German-Jewish academics who sought to diagnose - and, if at all possible, cure - the ills of society, particularly fascism and capitalism. In this book, Stephen Eric Bronner provides sketches of leading representatives of the critical tradition (such as George Lukács and Ernst Bloch, Theodor Adorno and Walter Benjamin, Herbert Marcuse and Jurgen Habermas) as well as many of its seminal texts and empirical investigations.
