Freeman Dyson, the eclectic physicist, took good aim at philosophy last week in a review of the silly book by Jim Holt, Why Does the World Exist?" An Existential Detective Story. Holt went around to "a portrait gallery of leading modern philosophers," and asked them the Leibnizian question: Why is there something rather than nothing?" The book offers their answers, along with biographical descriptions.
For Dyson, Holt's book "compels us to ask" these "ugly questions." First, "When and why did philosophy lose its bite?" Philosophers were, once important. In China, Confucius and his followers made a civilization. So too in Greece did Socrates and then the schools of Plato and Aristotle give birth to the western world. In the Christian era Jesus and Paul, then Aquinas and Augustine granted depth to dominant worldviews. Philosophers like Descartes, Hobbes, and Leibniz were central figures in the scientific revolution, and philosophical minds like Nietzsche, Heidegger, and Arendt (even if one was a philologist and the other two refused the name philosopher) have become central figures in the experience of nihilism. Against these towering figures, the "leading philosophers" in Holt's book cut a paltry figure. Here is Dyson:
Holt's philosophers belong to the twentieth and twenty-first centuries. Compared with the giants of the past, they are a sorry bunch of dwarfs. They are thinking deep thoughts and giving scholarly lectures to academic audiences, but hardly anybody in the world outside is listening. They are historically insignificant. At some time toward the end of the nineteenth century, philosophers faded from public life. Like the snark in Lewis Carroll's poem, they suddenly and silently vanished. So far as the general public was concerned, philosophers became invisible.
There are many reasons for the death of philosophy, some of which were behind Hannah Arendt's refusal to call herself a philosopher. Philosophy was born, at least in its Platonic variety, from out of the thinker's reaction to the death of Socrates. Confronted with the polis that put the thinker to death, Plato and Aristotle responded by retreating from the world into the world of ideas. Philosophical truth separated itself from worldly truths, and idealism was born. Realism was less a return to the world than a reactive fantasy to idealism. In both, the truths that were sought were otherworldly truths, disconnected to the world.
Christianity furthered the divorce of philosophy from the world by imagining two distinct realms, the higher realm existing beyond the world. Science, too, taught that truth could only be found in a world of abstract reason, divorced from real things. Christianity and science together gave substance to the philosophical rebellion against the world. The result, as Dyson rightly notes, is that philosophy today is as abstract, worldly, and relevant as it is profound.
What Dyson doesn't explore is why philosophers of the past had such importance, even as they also thought about worlds of ideas. The answer cannot be that ideas had more import in the past than now. On the contrary, we live in an age more saturated in ideas than any other. More people today are college educated, literate, and knowledgeable of philosophy than at any period in the history of the world. Books like Holt's are proof positive of the profitable industry of philosophical trinkets. That is the paradox—at a time when philosophy is read by more people than ever, it is less impactful than it ever was.
One explanation for this paradox is nihilism—The devaluing or re-valuing of the highest values. The truth about truth turned out to be neither so simple nor singular as the philosophers had hoped. An attentive inquiry into the true and the good led not to certainty, but to ideology critique. For Nietzsche, truth, like the Christian God, was a human creation, and the first truth of our age is that we recognized it as such. That is the precondition for the death of God and the death of truth. Nihilism has not expunged ideas from our world, but multiplied them. When speaking about the "true" or the "good" or the "just," Christians, Platonists, and moralists no longer have the stage to themselves. They must now shout to be heard amongst the public relations managers, advertisers, immoralists, epicureans, anarchists, and born again Christians.
Dyson ignores this strain of philosophy. He does point out that Nietzsche was the last great philosopher, but then dismisses Heidegger who "lost his credibility in 1933" and even Wittgentstein who would remain silent if a woman attended his lectures until she would leave. And yet it is Heidegger who has given us the great literary masterpieces of the 20th century philosophy.
His work on technology (The Question Concerning Technik) and art (The Origins of the Work of Art) has been widely read in artistic, literary, and lay circles. It is hard to imagine a philosopher more engaged with the science and literature than Heidegger was. He read physics widely and co-taught courses at the house of the Swiss psychiatrist Medard Boss and also taught seminars with the German novelist Ernst Jünger.
It seems worthwhile to end with a poem of Heidegger's from his little book, Aus der Erfahrung des Denkens/From Out of the Experience of Thinking:
Drei Gefahren drohen dem Denken
Die gute und darum heilsame Gefahr ist die Nachbarschaft des singenden Dichters.
Die böse und darum schärfste Gefahr ist das Denken selber. Es muß gegen sich selbst denken, was es nur selten vermag.
Die schlechte und darum wirre Gefahr ist das Philosophieren.
Three dangers threaten thinking.
The good and thus healthy danger is the nearness of singing poetry.
The evil and thus sharpest danger is thinking itself. It must think against itself, something it can do only rarely.
The bad and thus confusing danger is philosophizing.
