And Jim Holt most certainly does love it:
- "I found this idea of a hidden cosmic algebra — an algebra of being! — irresistible."
- "If you turn on your television and tune it between stations, about 10 percent of that black-and-white speckles static you see is caused by photons left over from the birth of the universe. What greater proof of the reality of the Big Bang — you can watch it on TV."
- "As the German diplomat and philosopher Max Scheler wrote, 'He who has not, as it were, looked into the abyss of the absolute Nothing will completely overlook the eminently positive content of the realization that there is something rather than nothing.'"
When I was about 12, my best friend and I collaborated on a poem. We called it "Everything is Nothing," or maybe it was "Nothing Is Everything." Mostly, it was an extensive word game, bending semantics to our will, but there was a burgeoning metaphysics — just a hint — about it, too. It made us hypothesizers. I grew up being that kind of person, who now likes this kind of book.
Jim Holt's question to many is naïve. It seems a lot of philosopher simply don't take the problem of nothing seriously anymore.
"I could understand why someone might think the mystery of existence was, by its very nature, insoluble. But to laugh it off as a pseudo-problem seemed a bit too cavalier. Still, if Grunbaum turned out to be right. the whole quest to explain the existence of the world would be a colossal waste of effort, a fool's errand. Why bother trying to solve a mystery when you can simply dissolve it?"
This book then is a survey of 20th-century philosophy. Holt looks to philosophers, scientists, mathematicians, economists, novelists, his mother, and Woody Allen. As Parfit "hated the 'naturalizing' of epistemology — the idea that the project of justifying our knowledge should be taken away from philosophers and given to cognitive scientists," Holt's book attempts to straddle the rift.
I learn that the now obsolete steady-state theory of the universe was allegedly inspired by a 1945 British horror film, Dead of Night. This awes me. This is the coolest movie I ever saw, or so I thought when I saw it when I was 11. I'm pretty sure this was a year before the Nothing poem. We had to write a radioplay, and I based mine on the coolest movie I'd ever seen, and then my script was one of the plays chosen to be produced. I'd asked my teacher to supply some text — something highfalutin and jargon for the psychiatrist to spout out. So the movie — there's a psychiatrist, goes to work, hears some pretty wacky, creepy supernatural stories in group therapy and at a climactic point wakes up to discover, relieved, that it was all a dream. And his day starts over exactly as it had already unfolded in his dream. It's a loop. So the thing is, 30+ years and I never knew the name of this movie, and Jim Holt brought it to me again and explained how truly significant it was.
Quite apart from steady-state theories, Holt raises lots of arguments that beg to have their assumptions examined:
- It is more perfect to exist than not to exist.
- The reason there is Something rather than Nothing is, as they fancifully put it, that nothingness is unstable.
- A self-subsuming principle is certainly preferable to a brute fact.
- Are the laws of physics somehow to inform the Abyss that it is pregnant with Being?
- No explanation of reality is capable of explaining itself.
- A cosmic possibility chosen at random is overwhelmingly likely to be thoroughly mediocre.
- The existence of this cosmos can be fully explained only on the assumption that it is middling in every way — a vast Walpurgisnacht of mediocrity.
Holt, with the help of Alex Vilenkin, finally achieves a precise definition of nothingness: "a closed spacetime of zero radius."
Surprise, Holt doesn't actually find an answer to his question. Also not surprisingly, there are several hints along the way that while it's important to ask the question, the answer doesn't really matter.
I had a passing familiarity with several of the concepts discussed in this book. While I've picked up a few new facts and technical details, this book has not swayed me in my beliefs. However.
However — and now we move on to the third part of the axiarchic case — is it really plausible that the explaining reason should be that this world is better than an ontological blank? Actually, the axiarchist is committed to a much stronger thesis. He must believe that the world is not merely better than nothing. but that it is maximally good, infinitely good, the nicest reality that money can buy.
There's this theory that the universe exists because it ought to exist (I think it's John Mackie; I remember using a text of his in Moral Philosophy). And even while I think the theory's kind of stupid, it put a smile on my face, and I consider the possibilities of there being something to that. Holt's book has helped me rediscover my awe.
Everything is as it should be.
The Basic Question — Sarah Bakewell in The New York Times
He is an urbane guide, involving us in his personal adventures. We join him for a weekend sipping claret and reading Parfit in a bathtub at the Athenaeum Club in London. He takes us to Paris for no good reason except to sit in the Café de Flore with a volume of Hegel. We stay with him through the death of his dog, and — movingly — even attend his mother’s deathbed, where she undergoes "the infinitesimal transition from being to nothingness."
What Can You Really Know? — Freeman Dyson in the New York Review of Books
When and why did philosophy lose its bite? How did it become a toothless relic of past glories? These are the ugly questions that Jim Holt’s book compels us to ask. Philosophers became insignificant when philosophy became a separate academic discipline, distinct from science and history and literature and religion. The great philosophers of the past covered all these disciplines.
Has the Meaning of Nothing Changed? — Ron Rosenbaum in Slate
Why should you care about nothing? Well, I know what I care most about is the purity of the nothing invoked in this maddening question. Pure nothingness: It’s the last unspoiled, uncluttered concept in the cosmos. I don't believe in God, but I do believe in Nothing, in the sense I want to believe in mysteries beyond the reach of the mind. It makes life more interesting if existence can't yet be reduced to a series of equations.Excerpt.
