Euhemerus and the Bullshit Artist

August 12, 2016 Mark DavisLeave a comment

Sailing down through the Middle East, past the monuments of Egypt and the wild African coast, and then on into the Indian Ocean, past Arabia Felix, Euhemerus came upon an island. Maybe he came upon it. Maybe he sailed. He was perhaps—yes, perhaps; who can say?—sailing for Cassander in deconstructing the memory of Alexander the Great. And that island, Panchaea, held a temple of Zeus with a written history of the deeds of men who became the Greek gods.

They were elevated, they became fixed in the freckled amber of ancient history, their deeds escalated into myths and legends. And, likewise, the ancient tribes of the Levant brought their El and Yah-Wah, and Asherah and Baal, and then the Zoroastrians influenced the diaspora in refuge in Babylon, until they returned and had found dualism, elemental good and evil, and then reimagined their origins pantheon down through monolatry and into monotheism. These great men and women were reimagined into something transcendent and, ultimately, barely understandable.

Even the rational Yankee in Twain’s Connecticut Yankee in King Arthur’s Court realizes almost immediately why he would soon rule over the medieval world as he is declared a wild dragon when presented to the court. He waits for someone to point out that he doesn’t resemble a dragon, but the medieval mind does not seem to question the reasonableness of the mythic claims, even in the presence of evidence.

So it goes with the human mind.

And even today we have Fareed Zakaria justifying his use of the term “bullshit artist” for Donald Trump. Trump’s logorrhea is punctuated by so many incomprehensible and contradictory statements that it becomes a mythic whirlwind. He lets slip, now and again, that his method is deliberate:

DT: Therefore, he was the founder of ISIS.

Build Up That Wall

April 13, 2016April 13, 2016 Mark Davis1 Comment

No, I’m not endorsing the construction of additional walls between the United States and Mexico. There are plenty of those and they may be of questionable value. Instead, it is Thomas Jefferson’s birthday and I’m quoting from Christopher Hitchens (who shared his birthday with Jefferson) in repurposing and inverting Reagan’s famous request of Gorbachev. Hitch promoted the Jeffersonian ideal of separating out the civic from the religious:

Be it enacted by General Assembly that no man shall be compelled to frequent or support any religious worship, place, or ministry whatsoever, nor shall be enforced, restrained, molested, or burthened in his body or goods, nor shall otherwise suffer on account of his religious opinions or belief, but that all men shall be free to profess, and by argument to maintain, their opinions in matters of Religion, and that the same shall in no wise diminish, enlarge or affect their civil capacities.

from Jefferson’s Virginia Statute for Religious Freedom

A rather remarkable continuation of Enlightenment concepts that derive, typically, from a notion of “natural rights” and, even in the Virginia Statue, from religious concepts: “Whereas, Almighty God hath created the mind free.” With the following paragraphs noting that human rulers are fallible and have tended to create false religions down through time, apparently regardless of God’s wishes.

Natural rights are an interesting idea that re-occurs in the Declaration of Independence and were also championed by George Mason in the Virginia Declaration of Rights. The notion that natural rights did not extend to slaves was something that Jefferson was conflicted about, according to Hitchens, until the end of his life, with the issue of state’s rights a pragmatic basis for opposition to an institution that he both profited from and found morally repugnant.… Read the rest

Against Superheroes: Section 18 (Chapter 15)

November 25, 2015November 27, 2015 Mark Davis1 Comment

The sessions with Sakara were illuminative and intimate. She asked me about what I remembered from before the transformation. I sat in the chair across from her, the susurration of the air conditioning that seemed to feed the field projectors as much as our comfort was a constant presence beneath our discussion. I remembered very little: hints of childhood, more about the dig at Mt. Hasan, bits of Ela’s sexual mystique, strange flashes of schools and lights. Interrogating this past revealed very little new or surprising to me. I was candid about my limitations concerning the changes to my memory. I was also candid about how with the loss of a personal history came, inevitably, a loss of the essentials of being human. We are continuitities of experience. I can’t describe who I am except as part of my memories and the feelings that surround and enervate them. The protracted calamity of religious ideas that Sakara raised, from ethical concerns about harming others to the status of the unborn all unravel with this consideration. A baby is alive but only tentatively human in the strongest sense. A god knows this—can even feel it as a ribbon into the future—but humans just arbitrarily assign categories that are driven by misunderstandings of these cognitive postures.

Why were the gods so capricious, she asked me. Why were they so inhuman? They were good human questions but the answer hardly raised above this faint echo of incapacity. If your mind is subsumed in this web of temporal flux, if you recognize the flammability of experience, and where there are other islands of experiences too, like for a human that there is only instead a moving arc of intransitive expectations and plans, then what is left is the broader permamence of an ineffable now.… Read the rest

Neutered Inventiveness

October 11, 2015October 11, 2015 Mark DavisLeave a comment

I just received an award from my employer for getting more than five patents through the patent committee this year. Since I’m a member of the committee, it was easy enough. Just kidding: I was not, of course, allowed to vote on my own patents. The award I received leaves a bit to be desired, however. First, I have to say that it is a well-crafted glass block about 4″ x 3″ and has the kind of heft to it that would make it invaluable as a weapon in a game of Clue. That being said, I give you Exhibits 1 and 2:

Exhibit 1 is a cell-phone snap through the glass surface of my award at Leonardo da Vinci’s famous Vitruvian Man, so named because it was a tribute to the architect Vitruvius—or so Wikipedia tells me. Exhibit 2 is an image of the original sketch by da Vinci, also borrowed from Wikipedia.

And now, with only minimal scrutiny, my dear reader can see the fundamental problem in the borrowing and translation of old Vitruvius. While Vitruvius was deeply enamored of a sense of symmetry to the human body, and da Vinci took that sense of wonder as a basis for drawing his figure, we can rightly believe that the presence of all anatomical parts of the man was regarded as essential for the accurate portrayal of man’s elaborate architecture.

My inventions now seem somehow neutered and my sense of wonder castrated by this lesser man, no matter what the intent of the good people in charge of the production of the award. I reflect on their motivations in light of recent arguments concerning the proper role of the humanities in our modern lives.… Read the rest

Machine Learning and the Coming Robot Apocalypse

August 20, 2015August 16, 2020 Mark DavisLeave a comment

Slides from a talk I gave today on current advances in machine learning are available in PDF, below. The agenda is pretty straightforward: starting with some theory about overfitting based on algorithmic information theory, we proceed on through a taxonomy of ML types (not exhaustive), then dip into ensemble learning and deep learning approaches. An analysis of the difficulty and types of performance we get from various algorithms and problems is presented. We end with a discussion of whether we should be frightened about the progress we see around us.

Against Superheroes, Section 7 (Chapter 5)

April 23, 2015April 24, 2015 Mark DavisLeave a comment

Section 7

With Chapter 4 we see a combination of narrative forms. There is, first, the factual discussion of the details of the archaeological dig itself. There are the problems that arise from the details of the ground, the water, the shaft, the descent. These problems and the detailed resolution of them lend to a sense of consistent realism concerning the tasks at hand in the everyday lives of the protagonists. The level of detail is strikingly at odds with the other primary narrative form: Sinister’s soliloquy on the symbolism and history of other deities. The position of these paragraphs juxtaposed amongst the more detailed discussion has produced several potential explanations, the most important of which was the requirement for presaging the unknown technology and its role in past conflicts. While there is an element of that, as a memoir presenting a linear sequence of developments (remember that he was concerned about that presentation), it is equally plausible that his recollections were merely jumbled and possessed of a certain confused emotional state.

The content of the soliloquy is worth further analysis. The primary descriptions are of conquest of people and their gods against others. There is a spreading out of the various factions, Hellenists, Israelites, Romans, etc. They are constantly at war with one another and the more powerful gods subjugate the less powerful. The subtle indication that amongst at least some of them, the Hellenists, that the gods were somewhat distant to them is of particular interest because it begs the question of how, amongst all the spirits and entities that are referenced, they were applied during war? What means of attack and influence did they have that apparently led to them conquering Yahweh and others?… Read the rest

Informational Chaff and Metaphors

March 7, 2015 Mark DavisLeave a comment

I received word last night that our scholarship has received over 1400 applications, which definitely surprised me. I had worried that the regional restriction might be too limiting but Agricultural Sciences were added in as part of STEM so that probably magnified the pool.

Dan Dennett of Tufts and Deb Roy at MIT draw parallels between informational transparency in our modern world and biological mechanism in Scientific American (March 2015, 312:3). Their article, Our Transparent Future (related video here; you have to subscribe to read the full article), starts with Andrew Parker’s theory that the Cambrian Explosion may have been tied to the availability of light as cloud cover lifted and seas became transparent. An evolutionary arms race began for the development of sensors that could warn against predators, and predators that could acquire more prey.

They continue on drawing parallels to biological processes, including the concept of squid ink and how a similar notion, chaff, was used to mask radar signatures as aircraft became weapons of war. The explanatory mouthful of the Multiple Independent Reentry Vehicle (MIRV) with dummy warheads to counter anti-ballistic missiles were likewise a deceptive way of reducing the risk of interception. So Dennett and Roy “predict the introduction of chaff made of nothing but megabytes of misinformation,” designed to deceive search engines of the nature of real info.

This is a curious idea. Search engine optimization (SEO) is a whole industry that combines consulting with tricks and tools to try to raise the position of vendors in the Google rankings. Being in the first page of listings can be make-or-break for retail vendors, and they pay to try to make that happen. The strategies are based around trying to establish links to the vendor from individuals and other pages to try to game the PageRank algorithm.… Read the rest

The Rise and Triumph of the Bayesian Toolshed

January 17, 2015January 18, 2015 Mark DavisLeave a comment

In Asimov’s Foundation, psychohistory is the mathematical treatment of history, sociology, and psychology to predict the future of human populations. Asimov was inspired by Gibbon’s Decline and Fall of the Roman Empire that postulated that Roman society was weakened by Christianity’s focus on the afterlife and lacked the pagan attachment to Rome as an ideal that needed defending. Psychohistory detects seeds of ideas and social movements that are predictive of the end of the galactic empire, creating foundations to preserve human knowledge against a coming Dark Age.

Applying statistics and mathematical analysis to human choices is a core feature of economics, but Richard Carrier’s massive tome, On the Historicity of Jesus: Why We Might Have Reason for Doubt, may be one of the first comprehensive applications to historical analysis (following his other related work). Amusingly, Carrier’s thesis dovetails with Gibbon’s own suggestion, though there is a certain irony to a civilization dying because of a fictional being.

Carrier’s methods use Bayesian analysis to approach a complex historical problem that has a remarkably impoverished collection of source material. First century A.D. (C.E. if you like; I agree with Carrier that any baggage about the convention is irrelevant) sources are simply non-existent or sufficiently contradictory that the background knowledge of paradoxography (tall tales), rampant messianism, and general political happenings at the time lead to a likelihood that Jesus was made up. Carrier constructs the argument around equivalence classes of prior events that then reduce or strengthen the evidential materials (a posteriori). And he does this without ablating the richness of the background information. Indeed, his presentation and analysis of works like Inanna’s Descent into the Underworld and its relationship to the Ascension of Isaiah are both didactic and beautiful in capturing the way ancient minds seem to have worked.… Read the rest

On Killing Kids

November 27, 2014 Mark DavisLeave a comment

Mark S. Smith’s The Early History of God is a remarkable piece of scholarship. I was recently asked what I read for fun and had to admit that I have been on a trajectory towards reading books that have, on average, more footnotes than text. J.P. Mallory’s In Search of the Indo-Europeans kindly moves the notes to the end of the volume. Smith’s Chapter 5, Yahwistic Cult Practices, and particularly Section 3, The mlk sacrifice, are illuminating on the widespread belief that killing children could propitiate the gods. This practice was likely widespread among the Western Semitic peoples, including the Israelites and Canaanites (Smith’s preference for Western Semitic is to lump the two together ca. 1200 BC because they appear to have been culturally the same, possibly made distinct after the compilation of OT following the Exile).

I recently argued with some young street preachers about violence and horror in Yahweh’s name and by His command while waiting outside a rock shop in Old Sacramento. Human sacrifice came up, too, with the apologetics being that, despite the fact that everyone was bad back then, the Chosen People did not perform human sacrifice and therefore they were marginally better than the other people around them. They passed quickly on the topic of slavery, which was wise for rhetorical purposes, because slavery was widespread and acceptable. I didn’t remember the particulars of the examples of human sacrifice in OT, but recalled them broadly to which they responded that there were translation and interpretation errors with “burnt offering” and “fire offerings of first borns” that, of course, immediately contradicted their assertion of acceptance and perfection of the scriptures.

More interesting, though, is the question of why might human sacrifice be so pervasive, whether among Yahwists and Carthiginians or Aztecs?… Read the rest

Inequality and Big Data Revolutions

October 25, 2014October 26, 2014 Mark DavisLeave a comment

I had some interesting new talking points in my Rock Stars of Big Data talk this week. On the same day, MIT Technology Review published Technology and Inequality by David Rotman that surveys the link between a growing wealth divide and technological change. Part of my motivating argument for Big Data is that intelligent systems are likely the next industrial revolution via Paul Krugman of Nobel Prize and New York Times fame. Krugman builds on Robert Gordon’s analysis of past industrial revolutions that reached some dire conclusions about slowing economic growth in America. The consequences of intelligent systems on everyday life will have enormous impact and will disrupt everything from low-wage workers through to knowledge workers. And how does Big Data lead to that disruption?

Krugman’s optimism was built on the presumption that the brittleness of intelligent systems so far can be overcome by more and more data. There are some examples where we are seeing incremental improvements due to data volumes. For instance, having larger sample corpora to use for modeling spoken language enhances automatic speech recognition. Google Translate builds on work that I had the privilege to be involved with in the 1990s that used “parallel texts” (essentially line-by-line translations) to build automatic translation systems based on phrasal lookup. The more examples of how things are translated, the better the system gets. But what else improves with Big Data? Maybe instrumenting many cars and crowdsourcing driving behaviors through city streets would provide the best data-driven approach to self-driving cars. Maybe instrumenting individuals will help us overcome some of things we do effortlessly that are strangely difficult to automate like folding towels and understanding complex visual scenes.

But regardless of the methods, the consequences need to be considered.… Read the rest
