Time (Lapham's Quarterly 7:04)

 Lapham’s Quarterly 7:04: Time (2014) How do you think about time? Is it a river that carries us along? Is it some abstract something that passes? Is it something that one spends, and once spent, is gone forever?

These metaphors and more are the ways we conceive of Time. Physicists point out that time is a conundrum. On the one hand all closed systems tend towards disorder. Open systems can scavenge energy that drives transformations that maintain or increase order. When that external energy input stops, the system decays into increasing disorder. Thus the forward direction of the Arrow of Time, which we experience as the flow or passing of time.

Expressions and musings about that experience form the bulk of this collection. Any reader will recognise their own experience and thoughts represented here. But there’s almost nothing about time as an aspect of reality.

Albert Einstein’s theories play a cameo role. More recent (and current) problems with time as a physical fact, or an aspect of reality, don’t show up at all. So let me offer a few musings of my own.

For us humans, the central fact of time is that for each of us it will end. For some that end


comes before the body disintegrates, when dementia destroys memories, and in doing so destroys the self. Knowing that this could happen to me creates a dread that I hurriedly push down below the tissue-thin surface of mind that I experience as my self. Time is the essence of what the brain constructs as my experience of reality. Consciousness exists only while it’s happening. That means my self, me, I exist only while I’m happening. Maybe that’s why the Christian creed asserts a belief in the resurrection of the body.

When I was growing up, the usual measure of distance was time. The next village was a half-hour away. Gruber’s farmstead was 3/4 hour away. The post office was 5 minutes away. And so on. So Einstein’s space-time to me seemed fairly obvious when I first read about it. Of course, I didn’t know the math that combines these aspects of reality. But I knew that moving through space always took time. Einstein’s space-time clarifies this: To move through space requires movement through time.

So what happens when we are standing still? Why do we still move through time? Well, we stand still within our frame of reference. But that frame of reference is moving with respect to every other frame of reference you care to specify. Which means we are not standing still. Which also means that time transcends frames of reference. Or that a frame of reference is specifiable only as moving through time. Which makes time, not space, the fundamental “whatever-it-is” of reality.

Maybe.

To exist means moving through time. When an entity ceases to exist, it disappears. But nothing disappears. So to cease to exist means to change into something else. 

Consciousness exists only while it’s happening. Anesthesia interrupts consciousness. Sleep is a different form of consciousness. When you “wake up from” from anesthesia, there is no sense that time has passed. Well, that’s my experience. But when I wake up from sleep, I know that time has passed, because I have memories of dreaming. I don’t know about comas, but descriptions of the experience suggest that comas are interruptions of consciousness like anesthesia.

Since consciousness exists only while it’s happening, time is of the essence of consciousness.

“Exist” implies time. Hence the question “Does God exist?” is a non-question, since by definition God is not in time but beyond it. (That phrasing shows that we can draw logical conclusions from statements that refer to things we cannot imagine.)

Time is a puzzle.

As always, this collection is an excellent overview and sampling of what humans have thought and imagined and reported about its topic. Recommended. ****

Delusions of Perfection (Lapham's Quarterly 7-02: Revolutions)


 Lapham’s Quarterly 7-02: Revolution (2014) Like the collection on States of War, this one is tough reading. People have committed more atrocities in the pursuit of an imagined perfection than for any other purpose. Religious persecution is one example. Revolution is the other. We should perhaps be thankful there is no third.

     There are many noble phrases recorded here, but they all express the same delusionary superstition that some final solution the the problems of humankind will usher in a perfect way of life. Reading them was bad for my equanimity and blood pressure.

A necessary read. Recommended. ****

Oh, To Be Young Again! (Youth, Lapham's Quarterly 7-03)

Lapham’s Quarterly 7-03: Youth (2014). “Youth’s a stuff will not endure” sang Feste the Fool in Twelfth Night. But the response to that insight is mixed. Some mourn what they recall as a time of promise and energy and sweet, sweet love of the world and the people in it. Others are glad it’s over, and they can, at last, embark on a life planned and controlled by themselves. The evidence gathered here suggests that the latter attitude is the more common one.



Me, what I recall from my childhood and youth surprises me in two ways. One, I can’t actually imagine the Me that was six or twelve years old. The photos of me, the letters that my mother kept, the oddments that I know were once precious to me, none of them translate into Oh, now I know what it was like. And two, when I think of the dumb-ass things I did as a teenager, I’m surprised I’m still here to remember them. A fraction of a second one way or the other would have meant my death.

Nevertheless, reading other people’s thoughts and reminiscences does trigger a hint of a feeling of what childhood and youth was like. The imagination supplies what memory cannot.

Medicine (Lapham's Quarterly 2-04, 2009)

 Lapham's’s Quarterly 2-04: Medicine (2009) Some random thoughts in response to this collection:

Archeologists and paleontologists have found evidence of care for the sick dating back millennia before the earliest medical texts. That care, and the signs of intentional burial, were both at one time believed to be species-specific behaviour. Observation of chimpanzees and elephants have blurred that picture, but there’s no doubt that humans have taken medicine very seriously. Every known society gives medical practitioners a special role and responsibility. The roles of physician and the priest are often combined. Cures are often understood as miracles: It’s not surprising that many of Jesus’s miracles were cures.

Through most of our history, what made us sick and what kept us well was summed up in precepts based on random observation. The history of medicine as a science is a nice example of how we humans strive to make sense of inadequate and often unreliable data. The first attempts to create a theoretical framework, the four humours, that might guide the practitioner to diagnose and treat unknown conditions we now know got it wrong. But based on the available data, it was reasonable. After all, whatever insight is claimed in one domain must match or at least not clash with whatever insights are claimed in another. The four humours of Greco-Roman medicine made sense, given what engineers and carpenters and farmers knew about how the material world worked, and what philosophers said about the four elements tied it all together..

Through most of history, medical practice dealt mostly with ameliorating symptoms. Sickness would strike without warning, and pandemics were common. I think it’s difficult for us to imagine the terror that sudden illness would provoke. The reactions to covid-19 show that nowadays we suffer not from the superstitious fear of plagues, but from the superstitious confidence that they won’t kill us.

Quacks have been with us from the beginning. Nowadays, many of them wear the mantel of wellness. I think quackery succeeds because science doesn’t provide the certainty people want from theories of Life, the Universe and Everything (TLUEs). The life sciences are especially prone to revise theories and replace them with more complicated ones. Quacks promise simplicity and certainty wrapped in pseudo-scientific jargon designed to create the illusion that here, at last, we have the Truth. “Natural” figures prominently in their claims. I guess most people just don’t know that the most lethal substances known are all natural. Mother Nature wins again. She always does.

Another wonderfully diverse collection. **** 

My Life Among The Apes (Fagan, 2012)

Cary Fagan. My Life Among the Apes. (2012) Short stories, winner of the 2012 Giller Prize. Some first-person, and mostly including a dash of sometimes dark comedy. Very Canadian, in that they tell of the mundane defeats and victories of our lives. Most feel autobiographical, and not just because of the 1st person narrator.

The title story is in part about the narrator’s infatuation with Jane Goodall’s work with chimpanzees. But we humans are apes, too. Just very clever ones. Clever enough to solve problems, but not clever enough to avoid the unpleasant consequences of some of the solutions. One of the sadder stories is about the narrator’s attempt to please the woman he’s about to dump by accompanying her on her dream vacation to learn chair-making. The after-story makes it clear that he never really understood what he lost. But that’s life.

Worth a read if you can find it. My copy was in the library’s summer book sale. ***
