Heidegger is without a doubt one of the most important thinkers in the history of the Western world. He called his philosophy a “fundamental ontology” because he wanted to show the very deepest foundations of Man’s understanding of himself and the world. His interest as a philosopher extended beyond the individual sciences to the underlying question of the meaning of life as a whole. His key question, then, was: “What is the meaning of Being?” But if we are to ask about the meaning of Being, and thus about the meaning of life, we must – so Heidegger argues – first look into the question of just what kind of being it is that poses such questions. This question-posing being, he says, is Man himself. Man is the only living being who can and must ask such questions. Man is constantly looking for orientation. This is why Heidegger also describes human life as a great challenge. Life does not live itself but rather requires constant decisions in order to be lived. But this also means that we can, potentially, fail to realize the meaning of our own life. Heidegger provocatively suggests that most people fail to live out their existence (as he puts it) “authentically”. He confronts us with the fact that, generally speaking, we live our lives doing “the things you’re supposed to do”. “You’re supposed” to go to school, then to university, to get a well-paid job, to take an annual holiday – and so this is what we do, how we live our lives. Instead of living authentic lives of our own, we stay within the tracks made safe and worn by others. But how do I know what life would be authentically mine? How do I make out the life that I am “destined” for? The book Heidegger in 60 Minutes uses key passages quoted from Heidegger’s own works to explain the philosopher’s famous “existential analysis” in a clearly comprehensible way. It takes the reader on an adventurous journey to the deepest structures of his or her own existence. There will surely be few readers of the chapters on the “’care’ character of human existence” or “anxiety in the face of nothingness” who will not recognize something of their own life-experience in the “existential” structures laid bare by Heidegger. In the chapter on “what use Heidegger’s discovery is to us today” it is then shown how broadly and topically relevant Heidegger’s thoughts still are for our personal lives and for the society of the 21st Century. The book forms part of the popular series Great Thinkers in 60 Minutes.

"Great Thinkers in 60 Minutes” is the second ‘omnibus’ volume drawn from the popular book-series of the same name. It comprises the five books, already published as separate volumes, "Marx in 60 Minutes", "Freud in 60 Minutes", "Sartre in 60 Minutes", "Camus in 60 Minutes", and "Heidegger in 60 Minutes". Each short study sums up the key idea at the heart of each respective thinker and asks the question: “Of what use is this key idea to us today?” But above all the philosophers get to speak for themselves. Their most important statements are prominently presented, as direct quotations, in speech balloons with appropriate graphics, with exact indication of the source of each quote in the author’s works. Between 40 and 80 representative passages are given from the work of each of the five philosophers. This light-hearted but nonetheless scholarly precise rendering of the ideas of each thinker makes it easy for the reader to acquaint him- or herself with the great questions of our lives. Because every philosopher who has achieved global fame has posed the “question of meaning”: what is it that holds, at the most essential level, the world together? There have emerged here a range of very different answers. In Marx, it is the relations of production – that is to say, the conditions under which we labour and produce the goods we need – which ultimately determine our sense of our lives, our thinking, and our whole culture. In Freud, it is the libido and thus the energy of our drives, which we can either live out, repress, or sublimate. In Sartre it is the absolutely free human will which compels Man to make himself what he is. In Heidegger, what absorbs us is the struggle for the authenticity of ‘Dasein’ and the ‘care’ for the Being of the world. Camus is the only philosopher in this series who gives no answer at all to the “question of meaning”. There is no “meaning”, says Camus; life is absurd and depends merely upon a sequence of random chance events. In other words, the meaning of the world and thus of our own lives remains, among philosophers, a topic of great controversy. One thing, though, is sure: each of these five thinkers struck, from his own perspective, one brilliant spark out of that complex crystal that is the truth.

Albert Camus was a legend in his own lifetime, as a successful author, a philosopher and a “ladies’ man”. His philosophical discoveries remain provocative even today. Because, like all great philosophers, Camus posed the question of the meaning of life. But his answer to this question was an answer of an entirely new kind. This question as to the meaning of life has been answered, of course, very differently down the centuries. For Plato it is ‘the Good’ that holds the world together; for Hegel the ‘World-Spirit’; for Marx the relations of production; for Sartre freedom; for Nietzsche ‘will to power’; and for Habermas the development of communicative reason. Really, each philosopher has his own answer to this question. But Camus is the exception here. He has none. Or rather, worse: he has an answer, but one of very sobering effect. His answer to the question ‘what is the meaning of life?’ is simply ‘It has no meaning. Life is absurd’. We plan ahead and make decisions, but in the last analysis our whole life depends on a series of chance events over which we have no control. Nor is there really a goal. Nevertheless, it is our task to live proudly and undauntedly on. Camus compares the life of Man with the myth of Sisyphus. The mythical Sisyphus strained tirelessly to push a boulder up a mountainside, even though it always rolled back down before he reached the top. But precisely in this apparently senseless and absurd activity lay, argued Camus, a chance for a fulfilled life. Camus explains to us how we can live with absurdity. We must, he says, imagine Sisyphus happy. The book Camus in 60 Minutes explains, using selected quotations and examples, this theory of “the absurd” as it is developed by Camus in his main philosophical works The Myth of Sisyphus and The Rebel. The chapter on “what use Camus’ discovery is for us today” describes the “absurd style of life” that Camus recommends. Camus’ colourful examples of “absurd life-projects”, and his descriptions of how one best confronts “the absurd” itself and leads a life without God or ideological orientation are, above all in our modern societies, of powerful relevance and topicality. The book forms part of the popular series Great Thinkers in 60 Minutes.

Never before or since has a single philosopher produced such a tremendous effect as Karl Marx. His great vision of a society without private property was heeded worldwide and had huge historical effects. Allegiance to his ideas was proclaimed by revolutionaries, parties, governments and states. Marxism spread all around the globe. Marxist revolutions occurred in countries as different as Russia, China, Vietnam, Cuba, Nicaragua and Mozambique as well as many others, until at one point almost a third of humanity were living under communism. But some hundred years after Marx’s death the communist world that he had inspired fell apart. After the fall of the Iron Curtain many claimed that Marx had been entirely in error and that the sole viable economic system is really capitalism after all. It was hoped that democracy, market economy, and a fair distribution of wealth could all be combined together. But this optimism did not last long. The global economic and financial crises of recent decades have profoundly shaken belief in the power of the market to regulate itself. It has become ever clearer that capitalism does indeed display the structural flaws that Marx described in his main work, Capital. Certain of Marx’s predictions, such as the forming of powerful economic monopolies and the ever-growing gulf between rich and poor, have already come true. Others can be seen approaching on the horizon of current social developments. His acute critique of capitalism is, then, more relevant today than ever. There is no question but that Marx still has a lot to say to us. The book Marx in 60 Minutes explains in clear and perspicuous terms, using some seventy key quotations from Marx’s works, such topics as the materialist philosophy of history, the doctrine of “base and superstructure”, Marx’s critique of religion, and the analyses developed in Capital of “surplus value”, capital accumulation, and the immiseration of the workers. In the second part of the book, entitled “Of what use is Marx’s discovery to us today?”, Marx’s insights are applied to the present situation. The book forms part of the popular series Great Thinkers in 60 Minutes.

The Viennese physician and psychoanalyst Sigmund Freud moved from hypnotizing his patients to interpreting their dreams and discovered thereby the hitherto unexplored dimension of the unconscious mind. Each of us, argued Freud, has hidden wishes, desires, and drives which influence our actions below the level of our awareness. A great role is played here, already from childhood on, by sexual desire and pleasure. The nursing infant still lives entirely by the “pleasure principle”, taking everything into his mouth, crying when he wants something, and laughing when he is satisfied. But he must soon learn to obey the rules set by his parents, teachers and society in general. The infantile “pleasure principle” is brutally superseded by the “reality principle”. This is an experience we all must undergo. But it is also one which sometimes leads to grievances and traumatization, as do other aspects of the development of our sexuality and of our relationships. Freud was a doctor and practiced a revolutionary method of treatment: psychoanalysis. He was the first to discover that the way people experience their own lives is often to be traced back to experiences which cannot, indeed, be altered but can be emotionally re-evaluated. Furthermore, Freud impressively explains how our “psychical apparatus” functions day to day and how we process in every second, with lightning speed, our drives, thoughts and perceptions. It was with good reason that the readers of the New York Times voted Freud the most important thinker of the 20th Century. The small book Freud in 60 Minutes explains Freud’s new and revolutionary perspective on human life step by step, by means of many examples and over forty quotes from Freud’s own works. Because all the key components of his theory – from the “oral stage”, the Oedipus Complex, the conflict of the drives, sublimation, repression, resistance, symptom-formation, transference, right on to the therapy itself – interlock with one another. In the second part of the book it is asked: “Of what use is Freud’s discovery to us today?” It is astounding how important and helpful his insights can be for forming and directing our own lives, provided they are applied rightly. The book forms part of the popular series Great Thinkers in 60 Minutes.

Sartre is surely one of the most important philosophers of the 20th Century. His “philosophy of existence” influenced not just academic debate but the whole of Western civilization, especially European youth. In France, from the end of WW2 on into the 1960s, a certain “youth culture” milieu composed of secondary school and university students and young artists and intellectuals proclaimed their “existential” attitude to life by wearing the black clothes and horn-rimmed glasses that Sartre was seen to wear in so many photos from the period. The motto of these “existentialists” ran: ‘do not let anyone else tell you how you are to live’. They advocated a frank and intensive style of life, both as regards friendships and love affairs and political commitments. Sartre was the great philosopher of freedom. No other philosopher has so strongly emphasized the freedom of the human will. And because Man is free he must make something out of his life and lives as he believes it right to live, if necessary contrary to existing social rules and traditions. Sartre, for example, opposed many of his country’s wars, fought for a more just society, launched many petitions, and carried on a so-called “open relationship” with his lifelong companion Simone de Beauvoir. In his principal work Being and Nothingness Sartre also became one of the first philosophers to explore the nature of “love”. How does love actually work? What does it mean to lead a free and self-determined life? How free are we? The book Sartre in 60 Minutes explains the most important of Sartre’s theses in a clear and comprehensible way, keeping close to Sartre’s own text and including over fifty selected passages from his work and focussing on the central theme of his ideas about freedom and the structure of inter-human relations. In the chapter on “what use Sartre’s discovery is to us today” it is then shown how important Sartre’s thoughts still are for our personal lives and for the society of the 21st Century. The book forms part of the popular series Great Thinkers in 60 Minutes.

Plato’s great discovery was radically new but has echoed down the ages. His “theory of Ideas” has shaped the whole of Western culture and his name is known worldwide. More than 2000 years ago Plato used his “allegory of the cave” – which envisaged people looking at shadows on a cavern wall and taking them for realities – to express a terrible suspicion. He saw his fellow Athenians living in a manipulated world of appearances – cut off from reality and “put to sleep” by material pleasures, wealth and demagogic politicians – and hoped, with this image, to shake them out of this sleep. Plato’s suspicions here are astonishingly relevant still in our Digital Age. Do we not also risk getting entirely lost in the shadows and projections of our TV-, Internet- and mobile-phone-dominated lives? To know truth, argued Plato, Man must learn to see again with his “inner eye”. We are able to sense the truth if we succeed in looking beyond the mere appearances. For behind the everyday objects that surround us, and the immediately visible world, there is another (invisible) reality, a sort of higher level of Being, which can reveal to us the world as it truly is. This second, higher reality is the realm of the “Ideas”: above all the Ideas of the Good, the True and the Beautiful by which we must be guided in our lives. But what exactly are these Ideas? Where do they come from? What does Plato mean when he speaks of “the Good”? And, most importantly, how can we know this “Good” and live a life in accordance with it? The book Plato in 60 Minutes uses three of Plato’s marvellous allegories – “the chariot”, “the sun”, and “the cave” – to explain the philosopher’s fascinating vision of the Ideas. But it also presents, citing key passages, Plato’s great political vision of an ideal state ruled by philosopher-kings. Finally, in a chapter on “what use Plato’s discovery is for us today”, it is shown how burningly relevant the ancient philosopher’s thoughts still are.
