Historical Consciousness and Deep Time: A Ramble

In my towers and stalagmite-like piles of books - I have over 30 out from the library as I write, as if I hadn't already had owned too many unread books! - and my horribly promiscuous reading in them, I recently realized how utterly different our perception of history and time has changed over the last mere 150 years.

In Stephen Jay Gould's Time's Arrow, Time's Cycle: Myth and Metaphor in the Discovery of Geological Time, he says the slowly-growing acceptance of "deep time" since 1860 (in the West, the Chinese and Hindus had much deeper conceptions than the world being around 6000 years old!) was of Galilean significance. I can "see" that now, but for most of my life I knew that historians and other intellectuals in the West had held to a very (relatively) recent timescale for history...even when fish fossils had been found at the top of mountains. The Flood, the Deluge had done it. It's all in the Bible.

I wasn't brought up on the Bible. That never made sense to me. I had to try to make sense of it by studying Western Civ textbooks, which I now realized just put the Garden of Eden in present-day Iraq, or Mesopotamia. And then I read many books like "C.W. Ceram"'s Gods, Graves and Scholars.

But what about all those Leaky findings...and "Lucy"? How to close the millions-year gap in my personal consciousness about the First Humans and...Barack Obama?

So I studied paleoanthropology, sociobiology, archaeology. What a difference between "history" and these disciplines!

A still-common notion, one I find personally hard to shake, is that "real" history only begins with writing. That just made so much stark sense to me for so long...and it made it easier to compartmentalize, say 3500BCE to now as One Thing, pre-writing humankind Another Thing.

Lately, coming back around to Gould's assertion about our consciousness of "deep time" since Lyell and Darwin, et.al, circa 1860: it still took a long time for college textbooks to incorporate anything about the Paleolithic humans. Even into the first decade of the 20th century, often a mere footnote in a 700 page book mentioned geological time and Paleolithic humans. Then, weirdly, history started with the Germanic hordes running roughshod over Europe!

I remember vividly going to a small bookshop in a smoggy little corner of the San Gabriel Valley, and the owner, knowing I thirsted for knowledge of such things, sold me a used two-volume copy of H.G. Wells's Outline of History. Now here was a history book that made sense to me. Finally! What a tremendous relief! Wells - one of the great Generalists of all time - takes up the first 50 pages with "The World Before Man." How long has Earth been around? (The book first arrived in 1919.) What about fossils and rocks? Climate, the Age of the Reptiles, the rise of mammals...he doesn't get to Neolithic Man until page 82! I still read these two volumes every five years or so. Now I have updated versions, like Jared Diamond.

                                    H.G. Wells, autodidact extraordinaire, seer, generalist, wrote for non-academics,
                                               which pissed the professors off, because he de-emphasized the 
                                               Great Man theory of history. We are here because of biology!

H.G. Wells. This was my first taste of deep time. Like an addictive drug, ever since my "first taste," all I want is more. To get a relatively short narrative about the time of humans before writing was fine, even thrilling at first, but after awhile, I realized there were huge expanses of time in which my imagination was urgently needed to fill in the gaps. And what gaps!

Still: like the Necker Cube, when I looked at it all in a different way, I was in awe of what we don't know, how long our great, great, great, great, great, great, great...grandfathers had been around, dealing with the elements, walking through unfathomably vast expanses of forest and savannah, using fire, communicating with each other in some way. I loved the psychological space! The great expanse of what we have only an inkling of, this feeling of immensity, of the abyss, or the sheer Long Shadow of time, even on the human scale, was vertiginous and thrilling. (I think the idea that others don't like that sort of "buzz" - not at all! - explains a lot about predispositions against a certain number of these types of ideas...)

Vico deals with this by telling his history based on the then-suddenly fashionable catastrophism of the Deluge. It's a clean break with ALL that went before; now: let us deal with history in that truncated period.

Or it was truncated to me. There seem some occult reasons why Vico would want to do this: first: as he lived and studied the reports of the New World were still exciting and it was pretty "wild" stuff. And the earliest writing that was available to him was paltry compared to what anyone can access in a well-stocked public library today. At least Vico tried to explain how language arose. And it's thrilling, but both Vico and I digress, literally.

But quite a lot of knowledge has accreted about our Paleolithic forebears over the last 150 years. Not writing, but, since around 1925, the idea that for all that Paleolithic time there was no absolute stasis, as was supposed by those who wished to hold to the metaphor of paying for being Fallen. No: the idea that self-consciousness arose then! A true, human theory of mind! ("I know that you know that I think that she's desirable, and I wonder what you are going to think if I do or say X?") But how? Some sort of catalyzing event, or series of events that happened over some period of time...made us...different.

A mutation? Accident of birth? A dietary change? Mating with exotic peoples from far over those hills? A relatively quick climate change? Obviously writing changed us: culture became Lamarckian. But before writing? What?

I like Terence McKenna's idea that we stumbled upon psilocybin mushrooms and it catalyzed human consciousness. Academic experts don't lend the idea much credence. But it's an interesting idea, and plausible, and some day I'll blogspew on it in more detail.

In only 500 years we've gone from the Earth being the center of the universe to the idea that we are in a universe that is not 6000 years old but about 13.7 billion years old, it had a beginning, it's expanding, presumably our local universe will undergo heat death when the energy is spread out enough, and there may be billions of other universes, branes, Dark Matter, strings...I think it says something basic about a person when I find out 1.) If they are conversant with these ideas, and 2.) If they tend to embrace them. 3.) If they don't embrace them, why not?

And I like to ask, when the time is right, "What do you think happened to give us a true human theory of mind?"

Here's 6 minutes of the spellbinding Terence McKenna on how we might have obtained a second-order theory of mind. I wish the sound was a little better:

On the Religious Function of Physicists

Recently I read in M.I.T.'s Technology Review this article. As a lay follower of quantum mechanics and cosmology, this was sheer gold; it gave me the frisson of the Ineffable. As a non-believer in any organized religion, especially any monotheistic creed, I cop the lion's share of my awe from...science. And for a long time I've thought that the public intellectuals - Third Culture-ists - who bring the uncanny, the weirdness from their fields: they serve as secular priests to the atheistic or agnostic Educated Classes.

Now, whether you skipped the link above or not, note how speculative it is, really. But the function of speculative thought is for us to play with those ideas for awhile; who knows, something might come of it. This seems related to abduction.

The multiverse idea seems lately to be taken more seriously by String Theorists, whose ideas are so marvelous it's about all the religion I need. At the same time, from an epistemological standpoint, String Theory seems overly Platonic, and there are severe problems with testing its ideas.

The other idea in the article - the so-called Many Worlds Hypothesis of quantum mechanics, says that, if we interpret the Schrodinger's Wave Equation, the most parsimonious solution is that, any time any observation is made, by anyone anywhere and anywhen, the universe splits into every possible outcome of that observation! First posed in the mid-1950s by Hugh C. Everett, R. Neill Graham, and the incomparable John Archibald Wheeler, it was largely taken as a "wild" idea, even if, of all the interpretations of quantum mechanics, the one that seemed best fit to survive Occam's Razor...it was not taken seriously until the 1970s, and has been gaining more converts since then.

Science fiction writers loved the idea from its beginning. You are reading the next blog over in another possible universe, according to this idea. You've never seen this blog. In another universe, I'm reading YOUR blog right at this very moment. I wanted to start a blog but thought maybe I ought to get a job instead. I was aborted in a billion other universes; in a trillion (I'm winging it, but who cares?) I was born a female. In another possible universe, I had followed the exact course the person who is writing followed, but then was killed eight years ago when visiting London; forgetting about the traffic difference, I stepped off a curb and you hit me. (There are more than enough universes in this theory that when I say "you" I literally mean anyone reading this blog.) It was an accident; try not to let it bother you! These things happen - theoretically - in this interpretation of quantum mechanics.

(I just hope you weren't hurt.)

According to this interpretation/abduction/hypothesis - which is taken quite seriously by many physicists with the PhD from highly reputable universities - you are or are not going to finish reading the OG dude's blog post. And the version of you that does has some sort of counterpart - in a matter of thinking - in another nearby universe in which you do finish this post. "They" - other "you"s - exist, in some philosophical-logical-mathematical sense. Why does this all feel like art? Like surrealism, or really good cannabis?

So, 30 years or so after the Everett-Wheeler-Graham hypothesis (abduction?), some String Theorists did their boggling-beyond abstruse mathematics and came up with an idea that there are possibly either an infinite number of universes or some Very Large Number of the them. Anything that can be imagined seemingly "really" exists in the sum total of those universes, because the physical laws "there" are different...

The late Professor George Carlin wondered in his Napalm and Silly Putty, "If there really are multiple universes, what do they call the thing they're all a part of?"-p.32
-----------------------------------
Edward Shils, a sociologist who also happened to have translated Karl Mannheim's Ideology and Utopia, once wrote in an essay in a book whose title I have forgotten: intellectuals have long served this function: as secular speakers particularly adept at relaying the marvelous to the masses, the given religion one subscribed to was one thing; we all want to hear a mindblowing story that just might be true!
-----------------------------------
In his book The End of Science John Horgan wrote about Ironic Science. What is it? Okay, well, most scientists are people who want to wake up in the morning and go to a secure area to work on a Problem. In this age, these days, those problems are so specialized it takes them 45 minutes to try to tell you what the problem is and why it's important, what's at stake, and why this part of the problem has proven difficult, etc. They need continued funding. Their 45 minute explanation you just heard might have been interesting to you, but politicians are usually morons compared to your understanding of science, and we're not even talking about the scientists themselves yet! So, they must WOW! the morons who control the money. So we get, say, Stephen Hawking, intoning via a remarkable device that, we're not far from "Knowing the mind of God." In the late 1970s, Carl Sagan reached the living rooms of Americans with Cosmos and enchanted us. Today we have Michio Kaku, who I think is better than Sagan in many ways, but I digress...Think of the emissaries from the world of science today: there are many; they have worm-holed their way into the popular imagination and colonized us: Neil de Grasse Tyson, Brian Greene. I'm not saying they're "lying," I'm just saying, "how much of this is a pitch?"


The point is: it's one thing for us Generalists to read all the latest popularizations about String Theory, Theories of Everything (TOEs), nanotechnology, exoplanets, robotics, cloud-computing, etc: but there may be something funny going on too: the specialist technical intelligentsia have gotten better and better at their own version of Public Relations. And perhaps a lot of that has to do with their need to romance us with possible marvels down the road, so they can keep the flow of funds fluid, so that they can get up tomorrow and work on that something-problem that, when explained, does not break down into a 20-second soundbite that fills us with awe and wonder.


But I'm only a Generalist, albeit an overweening one, so take all this with grain of salt...or some melatonin...or HGH?...or methylenedioxymethamphetamine?...or cannabis indica? (There seems more than one road to Religion.)

Hey! You finished reading! In n number of other worlds, you gave up earlier and went to porn, or email, or dinner, or... n number of "things." Now what will "you" do in "this" universe?
