Modern Uncertainty: “Meeting the Universe Halfway” 2016-08-23T09:17:39-04:00 Carl Gregg

A member of the congregation I serve emailed me recently on the topic about modern uncertainty:

In the nineteenth century, Robert Browning could write, “God ‘s in His heaven — All’s right with the world!” There was a high level of certainty that we were on the path to an earthly paradise. At the dawn of the twentieth century, quantum effects disrupted the view of science that nature was predictable at the most basic level. Wittgenstein questioned whether there indeed were any philosophical questions or only misunderstandings from the ambiguity of language. Goedel, then Turing and von Neumann shook the foundations of mathematics. Rorty points out that all is contingent, and the ascendency of Europe and America was only an accident of timing.”

Almost 2,500 years ago Socrates loved to expose the ways that many people are deluded about how much they think they know. In contrast, Socrates used to brag that he was the wisest person in Athens not because he knew a lot, but because he was aware of how much he did not know. His advantage was in not fooling himself about his level of certain knowledge about the world. Twenty-five hundred years later, here in the early twenty-first century, we know that Socrates didn’t know the half of it! There’s so much more that we “know we don’t know” than Socrates could’ve ever dreamed of not knowing!

To quote one of the few lines from Donald Rumsfeld that is worth remembering: “There are known knowns…. There are known unknowns… But there are also unknown unknowns.” In the early twenty-first century, despite all we know, we are also increasingly aware of all the known unknowns — much of which is related to our finite human capacities of perception. As the scientist J.S. Haldane said about the implications of quantum mechanics: “The universe is not only queerer than we suppose, but queerer than we can suppose.”

And it is indeed true that when Browning published that poem in 1841, in the wake of the Industrial Revolution, it was much easier to make the argument that we were on our way, as a species, toward building a utopia on this planet. Relatedly to consider one of the nineteenth-century forebears to my Unitarian Universalist tradition (many of whom held utopian ideals), in 1886 the Unitarian minister James Freeman Clarke published his famous “Five Points of the New Theology” that were meant as both a rejection of the Five Points of Calvinism and touchstones for religion in a modern age. (Keep in mind that he was writing almost a century before Second-Wave Feminism):

      1. the fatherhood of God,
      2. the brotherhood of man,
      3. the leadership of Jesus,
      4. salvation by character, and…
      5. the progress of mankind onward and upward forever.

To elaborate briefly on what he meant:

      1. the fatherhood of God, [we share a common source]
      2. the brotherhood of man, [we are all part of the same family]
      3. the leadership of Jesus, [through emulating his ethics]
      4. salvation by character, [human freedom and responsibility]
      5. the progress of mankind onward and upward forever.

You can particularly see nineteenth-century optimism in that final point.

But during World War I in the early twentieth century, we saw that the technology of the Industrial Revolution not only had great promise for increasing our quality of life, but also had potential to cause carnage on a previously unimagined scale. Compared to Clarke’s optimism about the inevitable “progress of mankind onward and upward forever,” consider the first stanza of William Butler Yeats’ poem “The Second Coming,” written in 1919 in the immediate aftermath of World War I:

Turning and turning in the widening gyre

The falcon cannot hear the falconer;

Things fall apart; the centre cannot hold;

Mere anarchy is loosed upon the world,

The blood-dimmed tide is loosed, and everywhere

The ceremony of innocence is drowned;

The best lack all conviction, while the worst

Are full of passionate intensity.

One common way of tracing the history of ideas is that the turn from Modernism to Postmodernism began with the global trauma of the First World War — the move from a trust in One Grand, Overarching Narrative of Progress to many competing (and often contradictory) narratives about how the world is or should be.

It used to be more reasonable to understand our species and our planet as at the center of  “life, the universe, and everything.” But in the sixteenth-century, Copernicus decentered our planet, showing through careful observations that Earth is not the center of the universe, but instead merely the third rock from the sun. In the nineteenth century, Darwin decentered our species, showing through careful observations that we are not special creations “a little lower than the angels,” but merely a species “a little higher than the apes” and deeply interconnected to the ecosystems of this planet.

In the early twentieth century, our place in the universe got even wilder, when Einstein decentered space and time, showing the relativity of space and time, written now as one hyphenated word: space-time. As the particle physicist Karen BaradBarad explores in her excellent — but challenging — book titled Meeting the Universe Halfway: Quantum Physics and the Entanglement of Matter and Meaning, it turns out that, “Time is not a succession of evenly spaced individual moments…. Similarly, space is not a collection of preexisting points set out in a…container, as it were, for matter to inhabit.” Rather, in the words of one physicist, “Spaciality is intra-activity produced” (180-181). Not interactively — as if space and time were two separate things that come together. Rather, they are always already intra-active. Think about the different between inter-murals (“between” two rival schools) and intra-murals (competition from “within” a school). I’ll come back to this point soon.

In the seventeenth century, Isaac Newton (1642 – 1727) was a giant figure in the Scientific Revolution. He helped solidify the field of classical mechanics, hugely advancing our understanding of the laws of motion and of gravitation. Within the Newtonian paradigm, science in many ways seemed clear-cut and objective (107). Everything seemed to sort naturally into one category or another. A phenomena being observed might be, for example, either a particle or a wave (100).

But as scientists looked closer and closer, it turns out the universe is a lot messier and more complex than previously thought. We have well-documented, experimental results that “light manifests particle behavior under certain circumstances and wave behavior under other circumstances.” Similarly, “matter — not just light — manifests wave behavior under the right experimental circumstances.” This dynamic is called the “wave-particle duality paradox,” and is one among many examples of what is sometimes called “quantum weirdness” — which calls into question all those conveniently clear-cut categories of classical physics (83).

Related to uncertainty, one specific aspect of quantum weirdness that I should hasten to mention is “Heisenberg’s uncertainty principle,” which shows (at the quantum level) that the very act of observation changes the phenomenon being observed. So there is no possibility of being a neutral, objective observer — a notion, it turns out, that was always an unrealistic dream. We can only estimate probabilities and possibilities from our various intra-active, subjective points of view.

In the early twenty-first century, we’ve come a long way from the idea that we humans are a uniquely special creation at the center of life, the universe, and everything. There are so many more “known unknowns” that ever before. And we are right to have a certain level of humility in the face of so much modern uncertainty.

That being said, I would be remiss if I didn’t celebrate how much we do know here in the early twenty-first century. After all, we live in the age of smart phones, space travel, and the burgeoning promise of nanotechnology. It sometimes feels like our technology is getting closer and closer to Star Trek. (I’m preach each Sunday from an iPad, after all!) We live in an age in which we have moved from Visual-light microscopes (which many of us grew up with in science labs) through electron microscopes (which can examine the structure of molecules) to Scanning Tunneling Microscopes, which can “see” atoms (40). That’s incredible!

Moving to the final sentence of the email I received, the sender wrote, the American Pragmatist philosopher, Richard Rorty “points out that all is contingent, the ascendency of Europe and America was only an accident of timing.” Rorty is relatedly a famous social constructivist, who takes postmodern uncertainty to its extremes. While I am generally a big fan of Rorty, my favorite retort to his more extreme position that “everything is a social construction” is from novelist Philip K. Dick who liked to say that, “Reality is what doesn’t go away when you stop believing in it.”

Now, as I begin to turn toward my conclusion, allow me to try to “stick the landing.” Many western worldviews have historically been very human-centric as well as grounded in a perspective of separate individuals and external objects that could easily be divided into clear-cut categories. But Quantum Physics challenges this notion of original separateness. We are not separate beings who sometimes inter-relate with one another or with the world. Instead we are always already intra-related (139). 

Many objects around you may seem separate and solid, but if we were to examine it more closely with the right tools, we would see that at the atomic level, it is a buzzing sea of particles. As for the “void” between us or at the sub-atomic level:

it isn’t all that was supposed to be (or not be), either. According to quantum field theory, the vacuum is far from empty; indeed, it’s teeming with the full set of possibility of what may come to be. Matter is regularly created and destroyed. And the zoo of subatomic particles — including electrons, quarks, positrons, antiquarks, neutrinos, pions, pluons, and photons — isn’t comprised of simple individual objects occupying specific positions in the vacuum we call space and time: not only is that very idea…not to be taken for granted, but part of their very nature seems to be wrapped up in the bubbling sea of possibilities…. (354)

We are not, nor have we ever been, merely separate beings. We are intra-related becomings. We are deeply entangled, down to the quantum level (ix). We are not separate observers of our world; we are, instead, inextricably “part of that nature that we seek to understand” (26).

I’ll end you for now with this quote from the conclusion of Karen Barad’s book Meeting the Universe Halfway:

Meeting each moment, being alive to the possibilities of becoming, is an ethical call, an invitation that is written into the very matter of all being and becoming. We need to meet the universe halfway, to take responsibility for the role that we play in the world’s…becoming. (396)
