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.

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. The book forms part of the popular series Great Thinkers in 60 Minutes.

"Great Thinkers in 60 Minutes Volume 1" comprises the five books, already published as separate volumes, "Plato in 60 Minutes", "Rousseau in 60 Minutes", "Smith in 60 Minutes", "Kant in 60 Minutes", and "Hegel 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. 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 Plato, for example, the "Idea of the Good" is that to which we need to open our souls; in Rousseau, it is rather only in our own original nature that we need to trust; in Adam Smith, it is in self-interest, which spurs on each individual and is finally transformed, by an "invisible hand", into the common good; in Kant it is the application of Reason which frees us and makes us capable of extraordinary moral actions; and in Hegel, finally, everything is held together by the dialectical self-development of the World-Spirit, which drives onward from epoch to epoch through the deeds of individuals and of nations until it has finally reached its great goal. 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.

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.

Nietzsche has the reputation of being the most provocative and controversial of all philosophers. What he demanded of humanity was something tremendous: that we should develop beyond ourselves and become "overmen". Formerly, we could draw a meaning for our lives from religion. But this is no longer possible because, as Nietzsche says: "God is dead!" This brief dictum has echoed around the world. Man, Nietzsche argues, has freed himself, with the rise of the natural sciences, from all belief in a "beyond" and now has, for the first time, the chance to take his existence into his own hands. Most human beings, however, prove unable to fill the gap in their lives that the "death of God" has left. They continue to seek salvation in such new gods, or idols, as nationalism, socialism, racism, or capitalism. But instead of slipping into the blind worship of these new gods, or "godlets", we need - so argues Nietzsche - rather to trust in our own selves, allow our own "will to power" to unfold, and become "overmen". Just as flowers stretch up toward the sun and animals seek constantly after nourishment, we human beings too must struggle every day to secure our lives and render them richer and more intense. In daily life, conducting this struggle must always mean, in part, conducting it at other people's expense: whoever, for example, applies for a job as a manager and gets it will necessarily cause bitter disappointment among those who applied and failed. "One furthers one's ego always at the expense of others", writes Nietzsche. But "will to power" finds a whole series of very different forms of expression. The artist, the father of a family, the politician, the businessman, the employee, indeed every one of us individually, must find his or her own highly personal and particular path to self-development. "Become who you are!" "Nietzsche in 60 Minutes" explains his exhilarating philosophy step by step making use of some 160 of the most important passages from his works.

It was, of all people, to a Scottish philosopher of morality that there fell the role of intellectual forefather of capitalism. It was Adam Smith who was the first to recognize and describe, in 1776, the basic principle of the market economy. His magnum opus, The Wealth of Nations, is still looked on today as “the Bible of capitalism”. And indeed, for a period of ten years it was, after the Bible itself, the most-translated book on earth. Smith created the “magic formula” of the free play of supply and demand and his theory of “the invisible hand” spread like wildfire around the world, remaining still today the core of the capitalist market model. What is more, Smith provided a philosophical justification for capitalism in the form of a theory of human nature: Man, he argued, is by nature egoistic and self-interested. And nothing suits such a being so well as a market economy, because it gives everyone the chance to increase their wealth. But this, in the end, benefits all, since each of us, working at improving his or her own quality of life, is led willy-nilly, as if by an “invisible hand”, to promote also the welfare of society as a whole. Do egoistic energies really tend to be transformed into social prosperity in this way? How does the market model work? Can one really simply let the economy run its course? Is capitalism “natural”? The book Smith in 60 Minutes explains the incisive theories of this philosopher and economist in a clear and comprehensible way, using over 50 key passages from Smith’s own works. The final chapter on “what use Smith’s discovery is for us today” discusses both the triumphal progress of Smith’s market model and the catastrophic crises that capitalism’s triumph has brought with it. A thorough knowledge of Smith is indispensable for politicians, bankers and economic policy leaders. But really anyone who lives in a market economy – and there are few, today, who don’t – should be familiar with Smith’s basic ideas. The mechanism of the “invisible hand” and the free play of supply and demand are more than just theories. They form the very heart of the capitalist world and it is indispensable to know the economic and philosophical foundations of the social order in which we live. The book forms part of the popular series Great Thinkers in 60 Minutes.

The philosopher Epicurus (341-270 BC) has been controversial since antiquity. His provocative key idea is of compelling simplicity. Every human being possesses, by nature, an internal compass. In order to be happy he must do what causes him pleasure and joy and avoid what causes him unpleasure and harm. He writes: "Pleasure is the starting point and goal of living blessedly [...] (It is) our first innate good, and [...] our starting point for every choice and avoidance." Already newborns follow this "pleasure principle". But this discovery, which might at first seem so obvious, struck Epicurus's contemporaries as a monstrous provocation. The notion that the highest goal of life is enjoying pleasure stands in stark contrast to the then-established teachings of Plato, Aristotle and the Stoics. These latter saw reason and a life lived by reason as the highest goal of Man. Because Epicurus accepted women into his school and even had a love affair with one of them, his contemporaries called him a "glutton" and "sex fiend". The Greek poet Timon described him as "doggish", the Stoic Epictetus as a "wastrel". Christian authors later even called him the Antichrist. But these critiques are fundamentally false, because beyond a superficial striving for pleasure, Epicurus's deeper concern was a lifelong, painstaking "care of the self". His questions, then, remain burningly relevant. What are the basic human needs whose satisfaction yields a happy life? Which needs are really necessary to life and which not? How, concretely, should we deal with these needs: for example with the need for food, drink, sexual intercourse and friendship? The book contains almost a hundred quotes from this charismatic ancient philosopher. It appears as part of the beloved series "Great Thinkers in 60 Minutes" which has now been translated worldwide into six languages.

Habermas's great philosophical discovery is a rousing and a modest one. Rousing because almost two centuries after the great philosophers of history Hegel and Marx he attempts once again to discover a meaning and purpose for human history; modest because he describes without bombast humanity's ability to shape its own future and deduces this ability from a phenomenon we encounter in our daily life: language. It is no longer, as in Hegel, the World-Spirit nor, as in Marx, class struggle that forms the motor of development but rather human speech. Agreement achieved through language will, says Habermas, eventually unite humanity.The wish for such an ever greater agreement, based on an unforced exchange of views, is inherent in the structure of our speech. Because as soon as anyone speaks with anyone else anywhere on earth, he must, consciously or unconsciously, raise four universal validity-claims, such as the claim to be understood. What begins so simply is developed by Habermas in an hypothesis of great breadth. In communicative action, and thus in language, there inheres a stubborn claim to rationality, even if it is constantly suppressed. Does language really compel us to rationality? Does it really have such emancipatory power or is it, in the end, just a tool? And if language really causes humanity to draw closer together, why are there still wars? Habermas answers all these questions. The book "Habermas in 60 Minutes" explains the core of his philosophy using over 60 key quotations and many examples. The chapter "Of What Use is Habermas's Discovery to Us Today?" points up the meaning of his Critical Theory for our present world and for our personal lives. The book appears as part of the popular series "Great Thinkers in 60 Minutes".

Foucault counts as one of the great Post-Structuralists. Already his book-titles -"History of Madness", "Discipline and Punish", "The Use of Pleasure", "The Order of Things" - show his entirely new way of looking at things. He is also one of those philosophers who have become more, not less, influential after their death. This should both please and worry us. It is pleasing that Foucault's key ideas have remained so vital and relevant but worrying also because the main one among these ideas is so disturbing. "Man is erased, like a face drawn in the sand": With this thesis of "the end of Man", Foucault does not mean that we are about to die out as a species, for example through climate change. He means only that Man as we have hitherto known him, as a free, self-determined being spontaneously enjoying his own pleasures, is vanishing. This "Man" is being dissolved into the discourses and structures of our "carceral society", in indeed just the way that a face drawn in the sand is dissolved by the incoming tide. In the 18th century there was invented a new circular prison which allowed the warder to observe all the prisoners from a single central point. This feeling of being always observed has, Foucault argues, become the model for our whole society. But Foucault shows us, besides the origin of the structures of our coercive society, also a certain model for a modern "art of living". What does this model look like? Is it still possible at all to break out, as a true individual, from this "coercive society"? Is Foucault right to universalize his "prison paradigm" and say that we all feel constantly observed? Of the disturbing present relevance of his thoughts, in any case, there can be no doubt. The most important of these thoughts are explained here using over 100 key quotes. The book appears as part of the popular series "Great Thinkers in 60 Minutes".
