The work of the great philosophers of the past is well known. From Aristotle and Plato to Kant and Wittgenstein, the answers to life's biggest questions have been discussed and debated endlessly. But, as philosophy itself teaches, there is never a final solution to a philosophical problem.

In the search for higher meaning, Nicholas Fearn has travelled the globe to interview the world's most distinguished thinkers, from Derek Parfit, David Wiggins and Bernard Williams, to Donald Davidson, Richard Rorty and Bernard-Henri Lévi. Philosophy is a brilliant and compelling guide to the latest answers to the oldest questions, bringing to light what today's philosophers think about what it is to be human.

preface

All the interests of my reason, speculative as well as practical, combine in following three questions: (1) What can I know? (2) What ought I to do? (3) What may I hope?

Immanuel Kant

There is room for words on subjects other than last words. Indeed, the usual manner of presenting philosophical work puzzles me. Works of philosophy are written as though their authors believe them to be the absolutely final word on their subject.

Robert Nozick

The Great philosophers such as Aristotle, Immanuel Kant and Ludwig Wittgenstein achieved their status because they preferred revolution to evolution. They would rather introduce new ideas and systems than work with their predecessors’ materials. The result was that over two and half thousand years of philosophy, successive thinkers covered their subjects’ canvas with so many brushstrokes that no discernible image remained. Only lately has a restoration started to bear results. Layers have been removed and more naive cleanings discarded. Old impressions have been revealed as the ideas of ancient thinkers have gained new purchase, and contemporary inks have refreshed the strongest lines. This has been made possible by new techniques in the analysis of arguments, new ideas to test them on and new raw material provided by the sciences.

Now is an ideal time to take an audit of Western philosophy. This book assesses the current state of the philosophical art, taking a wide view of what has been achieved in recent years in the most hotly contested areas, and examines the latest approaches to problems that were first tackled in the ancient world. In order to complete my audit, I decided to consult a cross section of the main players in the key debates from various parts of the world. My task was made easier in the end by the concentration of most of the finest philosophical minds in a single – if large – place, the United States. It was made harder by the advanced age of the interviewees, several of whom, including Robert Nozick and W.V.O. Quine, died before I could get to see them. Most of those who survived were amenable, though some were more amenable than others. Several, such as David Chalmers, Jerry Fodor and Colin McGinn welcomed me into their homes, while others such as Thomas Nagel and Alasdair MacIntyre were so suspicious of journalists that they refused to speak to me. Daniel Dennett and Tyler Burge kindly allowed me second drafts and follow-up questions, while Jacques Derrida telephoned me before sunrise to decline to help when I was in no fit state to argue.

In the end I was able to interview over thirty of the world’s most prominent thinkers. After the first few meetings, I noticed that the conversation usually took the same direction. First they would inform me that, sadly, there had been little progress in philosophical understanding during their lifetime. Then they would begin a long exposition of evidence to the contrary. It seems that the typical modern philosopher is nothing if not modest. Philosophy has always suffered from excessive expectations, but if it is foolhardy to declare a final solution to any philosophical problem, it is equally rash to dismiss anything less as worthless. Over the past fifty years, revolution has gone out of fashion in the philosophical world. Answers have tended to come in a smaller size than those of the past – as, cynics would add, have the thinkers who proffer them. Even cynics, however, would admit that technical ability is at an all-time high. A decent graduate student in the subject today should be able to hold his own in a debate against any illustrious thinker from the ancient world. There are fewer gurus, fewer giants, but a greater division of labour in an increasingly fragmented and specialized field. On the face of it there is little agreement among these disparate schools, but the consensus is often stronger than it seems, for once a field has been more or less wrapped up, the researchers who persist in working in it tend to be the eccentrics. For example, most scientists are satisfied that aliens have not been visiting the Earth in flying saucers recently, yet a survey of the specialist literature on ‘alien abduction’ shows that the vast majority of so-called ‘experts’ are firm believers in UFOs and little green men. This is because most scientists have better things to do than tackle questions that have already been settled within reasonable doubt.

Philosophy has entered a ‘post-heroic’ age. Contemporary philosophers hope to advance our understanding incrementally as they build on a distributed achievement – the work of over twenty-six thousand professionals worldwide according to the Philosophical Documentation Center – informed by the latest work in the rest of the humanities and sciences. The role of the genius has diminished, perhaps because of a dearth of such individuals in recent years, perhaps due to the time it takes to recognize them as such, but more likely because the discipline has learned from its imperialistic mistakes. One of these mistakes is overreach. At the beginning of the nineteenth century, the German philosopher Georg Hegel used his philosophical system to predict that there could be only seven planets in the solar system. Today, one hopes, philosophers have a better idea of what can and cannot be achieved by reasoned argument. Neither do philosophers find it necessary to turn their subject on its head in order to solve philosophical problems. There is no need for revolution when constant, steady progress is already being made.

Today’s philosophers look back on at least five great revolutions in ideas. The first was the birth of reason as an instrument for divining truth in the fifth and sixth centuries BC, which comes to us through the surviving works of the Presocratic philosophers and the dialogues of Plato. Building upon the thoughts of his teacher, Socrates, Plato held our views to be correct or mistaken insofar as they corresponded with the otherworldly ‘Forms’ of Beauty, Goodness, Courage and the like. Plato held these templates to be objects in themselves – more real, in fact, than the objects that we find in the physical world, for they were perfect, pure, eternal and unchanging. He maintained that by employing reason properly we could come to see these truths and attain genuine knowledge with which to replace the mere ‘opinion’ with which we are normally satisfied. The only limit was the material we had to work with – for the physical world contains but inferior copies of the eternal truths.

In Königsberg in the eighteenth century, the second great revolution was effected when Immanuel Kant transferred the emphasis to the human subject. Everything we see and hear, everything the mind apprehends must, he thought, be shaped by the senses and the intellect for our comprehension. We can never behold the intrinsic nature of things as Plato dreamed. We can only ever know an anthropic version of God, Virtue and Beauty. In Kant’s formulation, the more familiar we become with the capabilities of our own minds, the closer we approach true knowledge. We can only understand the limits of our world by examining the limits of human thought.

The third great revolution took place at around the same time in Britain. John Locke and David Hume had worked the scientific methodology of their seventeenth-century predecessor Francis Bacon into a philosophical system known as ‘empiricism’. According to the empiricists, we could only know that which was within our experience. Reason alone could unearth nothing new, but merely rearticulate knowledge already furnished by the senses.

In the nineteenth century, a further revolution occurred when the German thinker Georg Hegel initiated the study of what Man may become rather than simply what he is, citing the historical forces that trump reason in the creation of new ideas and modes of living. His ‘dialectic’ traced the clash of opposing movements to chart ‘the progress in the consciousness of liberty’, and defined the state that embodied this development as ‘the march of God through the world’. Where Hegel attacked reason from above, his fellow countryman Friedrich Nietzsche undercut it with an appeal to motive. He argued that values were rendered true by the individual’s ‘Will to Power’ rather than any recourse to evidence and observation. At a stroke, Nietzsche provided the foundation for the anti-philosophy known as ‘postmodernism’ that remains so popular in humanities departments.

By the early twentieth century, the limits were drawn tighter as philosophers such as the Austrian Ludwig Wittgenstein created a fifth revolution by proposing that the boundaries of thought were delineated by the limits of the language in which it was conducted. The standards for assessing truth resided neither in the heavens nor in the confines of the mind, but in the grammar of public practice. Where philosophers imagined that they were examining the nature of things, all they were really doing, Wittgenstein and his followers argued, were taking words out of their context. The proper objects of study were, for Plato, semi-divine entities and, for Kant, the structures of consciousness. Now, ‘analytic’ philosophers were reduced to analysing the grunts and bodily jerks that human beings use to communicate. For excitement, they could hunt down and extinguish vestiges of metaphysical thinking and pronounce problems ‘dissolved’. For example, the English philosopher Gilbert Ryle argued that the question of where to locate the conscious self was a ‘category mistake’ of the kind made by someone who visits the colleges of Oxford and asks where the ‘university’ is, or watches a procession of battalions and regiments and asks when the ‘army’ will be marching past.

Western thinkers today are informed by all these shifts, but one in particular has captured their imagination in recent years: the empiricist promise of a ‘scientific’ philosophy. Bertrand Russell once compared the branches of human knowledge to a filing cabinet, in which the material discussed by philosophers was found in the compartment marked ‘Don’t Know’. Once we have found out enough about a given subject to approach its questions in a systematic way, the contents are moved into a new compartment with a new title, be it ‘Physics’, ‘Psychology’ or ‘Economics’. This is a fair description of the history of philosophy, which has periodically resulted in new disciplines, new sciences. It also explains the illusion that philosophy never achieves anything. Philosophers never get the credit for their successes, for once real progress has been made on a problem it is taken out of their hands and given to its new custodians. Sir Isaac Newton wrote the Principia and Adam Smith The Wealth of Nations as philosophers, but they are now remembered respectively as a physicist and an economist. The contemporary thinker Noam Chomsky is described as a philosopher as well as the founder of linguistics, but the former half of his title will one day be dropped from encyclopedias.
