Krauss: …Philosophy used to be a field that had content, but then “natural philosophy” became physics, and physics has only continued to make inroads. Every time there’s a leap in physics, it encroaches on these areas that philosophers have carefully sequestered away to themselves, and so then you have this natural resentment on the part of philosophers. This sense that somehow physicists, because they can’t spell the word “philosophy,” aren’t justified in talking about these things, or haven’t thought deeply about them—
Is that really a claim that you see often?
Krauss: It is. Philosophy is a field that, unfortunately, reminds me of that old Woody Allen joke, “those that can’t do, teach, and those that can’t teach, teach gym.” And the worst part of philosophy is the philosophy of science; the only people, as far as I can tell, that read work by philosophers of science are other philosophers of science. It has no impact on physics what so ever, and I doubt that other philosophers read it because it’s fairly technical. And so it’s really hard to understand what justifies it. And so I’d say that this tension occurs because people in philosophy feel threatened, and they have every right to feel threatened, because science progresses and philosophy doesn’t.
“Even the last remaining trump card of the theologian, ‘Why is there something rather than nothing?,’ shrivels up before your eyes as you read these pages. If ‘On the Origin of Species’ was biology’s deadliest blow to supernaturalism, we may come to see ‘A Universe From Nothing’ as the equivalent from cosmology. The title means exactly what it says. And what it says is devastating.”
“…it ought to be mentioned, quite apart from the question of whether anything Krauss says turns out to be true or false, that the whole business of approaching the struggle with religion as if it were a card game, or a horse race, or some kind of battle of wits, just feels all wrong — or it does, at any rate, to me. When I was growing up, where I was growing up, there was a critique of religion according to which religion was cruel, and a lie, and a mechanism of enslavement, and something full of loathing and contempt for everything essentially human. Maybe that was true and maybe it wasn’t, but it had to do with important things — it had to do, that is, with history, and with suffering, and with the hope of a better world — and it seems like a pity, and more than a pity, and worse than a pity, with all that in the back of one’s head, to think that all that gets offered to us now, by guys like these, in books like this, is the pale, small, silly, nerdy accusation that religion is, I don’t know, dumb.”
“When it comes to the real operational issues that govern our understanding of physical reality, ontological definitions of classical philosophers are, in my opinion, sterile. Moreover, arguments based on authority, be it Aristotle, or Leibniz, are irrelevant. In science, there are no authorities, and appeal to quotes from brilliant scholars who lived before we knew the Earth orbited the Sun, or that space can be curved, or that dark matter or dark energy exist do not generally inform our current understanding of nature. Empirical explorations ultimately change our understanding of which questions are important and fruitful and which are not.”
If all possibilities—all universes with all laws—can arise dynamically, and if anything that is not forbidden must arise, then this implies that both nothing and something must both exist, and we will of necessity find ourselves amidst something. A universe like ours is, in this context, guaranteed to arise dynamically, and we are here because we could not ask the question if our universe weren’t here. It is in this sense that I argued that the seemingly profound question of why there is something rather than nothing might be actually no more profound than asking why some flowers are red or some are blue. I was surprised that this very claim was turned around by the reviewer as if it somehow invalidated this possible physical resolution of the something versus nothing conundrum.
Instead, sticking firm to the classical ontological definition of nothing as “the absence of anything”—whatever this means—so essential to theological, and some subset of philosophical intransigence, strikes me as essentially sterile, backward, useless and annoying. If “something” is a physical quantity, to be determined by experiment, then so is ‘nothing’. It may be that even an eternal multiverse in which all universes and laws of nature arise dynamically will still leave open some ‘why’ questions, and therefore never fully satisfy theologians and some philosophers. But focusing on that issue and ignoring the remarkable progress we can make toward answering perhaps the most miraculous aspect of the something from nothing question—understanding why there is ‘stuff’ and not empty space, why there is space at all, and how both stuff and space and even the forces we measure could arise from no stuff and no space—is, in my opinion, impotent, and useless.
Krauss’ rejection of Leibniz’s famous question, “why is there something, rather than nothing?” reminds me a lot of Meillassoux in After Finitude. In the end, though, Krauss’ universe is made up of “stuff” and “space.” I don’t think it is inconsequential that he fails to mention time (be sure to watch Albert’s video linked above on time if you’ve read this far). It is the false spatialization of time that first sent physics astray from Naturphilosophie. Time is intensity, not extension. Krauss can’t help but picture the pre-big bang quantum vacuum of “no stuff and no space” as some kind of stuff in space. What if we temporalize the question of the nature of the physical universe, relating to it not as a given thing or set of things, but as an evolving community of life, a growing, changing, ensouled creature (ensouled, as in not just stuff in space, but an unfolding process)? All the sudden, the big bang is no longer an event which happened back then, 13.7 billion years ago. Creation is what the universe is still doing. Plato already intuited the fundamental presupposition of physical cosmology in Timaeus (Krauss’ formulation is but an obscure footnote): something (the limited) and nothing (the unlimited) have always already been mixed. This mixing constitutes the life of the universe as a moving image of eternity.
