The Vapors of Hell

Mark DavisLeave a comment

Since Plutonium has now been unearthed in Turkey–no, not the element, but the gates of the underworld where the Priests of Cybele got drunk on gases erupting from below the water table–it seems only appropriate to trace the historic, mythic, and semantic roots of the notion of Hell out from its roots in antiquity straight through to our modern representations.

We can draw a direct line from Tartarus to the concept of punishment and the afterlife that arose during the Hellenistic period and filtered into the Near East, and what better representation of the dangerous threats from deep beneath the earth than a cave that kills animals and makes people drunk on the fumes? Such a place must have captivated the minds of the ancients by providing a corporeal connection to the mythic dancing of the deities.

The great irony is that the Hierapolis and the Plutonium was bulldozed by Christians in the 4th to 6th century CE, thus destroying a touchstone of their own cosmology.… Read the rest

Signals and Noise: Chapter 00010101 (Ennui)

cover-design-epubWhat does one do when one is only living? What does one do when there is nothing to be done. Waking back to the abandoned reactor was already boring after only one night. It was late in the morning judging from the portals of light in the hall outside his cell. He was famished and athirst as he walked down to the central room. Only a few children milled between smoldering fires. He could smell food, though, and followed the scent. It was bacon, he thought, and his mouth began salivating. He hardly ever ate bacon, but he often craved it. He found older kids cooking in a functioning kitchen, though they had converted the sinks into fire pits and were toasting bread and frying bacon in iron skillets thrust into the hot coals. He waited in line for a helping and gobbled it down with his hands off the tin plate that they handed him. He looked behind the cooks and saw several large, blue coolers filled with milk cartons, eggs, and slabs of meat on top of mounds of ice. Zach thought that they must have brought that in this morning since there was no electricity at the facility.

A boy approached him as he leaned against a wall and drank deeply from the cup of milk that he had been given. You a hacker? the boy asked, stammering and averting his gaze just a bit as he spoke, then raising his eyes directly towards Zach until Zach returned the look. Yeah, I spose. Why? Oh, dunno. I’ve never touched a puter, he said, seeming proud of his accomplishment. Really? Zach asked. How long you been here? The boy grinned at him.… Read the rest

Curiouser and Curiouser

Mark DavisLeave a comment

georgeJürgen Schmidhuber’s work on algorithmic information theory and curiosity is worth a few takes, if not more, for the researcher has done something that is both flawed and rather brilliant at the same time. The flaws emerge when we start to look deeply into the motivations for ideas like beauty (is symmetry and noncomplex encoding enough to explain sexual attraction? Well-understood evolutionary psychology is probably a better bet), but the core of his argument is worth considering.

If induction is an essential component of learning (and we might suppose it is for argument’s sake), then why continue to examine different parameterizations of possible models for induction? Why be creative about how to explain things, like we expect and even idolize of scientists?

So let us assume that induction is explained by the compression of patterns into better and better models using an information theoretic-style approach. Given this, Schmidhuber makes the startling leap that better compression and better models are best achieved by information harvesting behavior that involves finding novelty in the environment. Thus curiosity. Thus the implementation of action in support of ideas.

I proposed a similar model to explain aesthetic preferences for mid-ordered complex systems of notes, brush-strokes, etc. around 1994, but Schmidhuber’s approach has the benefit of not just characterizing the limitations and properties of aesthetic systems, but also justifying them. We find interest because we are programmed to find novelty, and we are programmed to find novelty because we want to optimize our predictive apparatus. The best optimization is actively seeking along the contours of the perceivable (and quantifiable) universe, and isolating the unknown patterns to improve our current model.… Read the rest

Minimizing Existential Toaster Threats

Mark DavisLeave a comment

tesla2Philosophy in the modern world has strived for a sense of relevance as the sciences (“natural philosophy”) have become dominant. But philosophy may have found a footing in the complicated space between technological advances and defining human virtues with efforts to address and understand change and its impact on human existence. These efforts have included the ethics of biological manipulation and, critically, existential threats to humanity, including climate change, artificial intelligence, and genetic engineering.

I mention all this because I’m really writing about cars but need to fit the discussion somehow into the theme of this blog. So the existential threat of climate change means we need to pollute less and burn less fossil fuels. More tactically, however, my wife and I also needed to buy a new toaster because our five-year-old Oster four-burner unit was failing. There was therefore only one solution to this dilemma: take the brand new Tesla S 70 miles away to the foothills of the Sierra on a test drive and, yes, to buy a new toaster.

I had taken delivery of our Tesla S Performance 85 with Tech Package a week before but didn’t really have any opportunity to drive it because of work obligations that kept me firmly planted in front of a computer monitor. I had driven it briefly but it mostly sat charging in the garage (at the slowish pace of a 120V circuit; Tesla did not deliver my dual charger station in time and I haven’t had the 100A circuit installed to support it either), so when Saturday came, I realized that it was an opportunity to justify a longish trek to test the drivability of the car and to seek out and use the Tesla “supercharger” stations that promise rapid charging in 30 minutes to an hour.… Read the rest

Chinese Feudal Wasps

Mark DavisLeave a comment

waspsIn Fukuyama’s The Origins of Political Order, the author points out that Chinese feudalism was not at all like European feudalism. In the latter, vassals were often unrelated to lords and the relationship between them was consensual and renewed annually. Only later did patriarchal lineages become important in preserving the line of descent among the lords. But that was not the case in China where extensive networks of blood relations dominated the lord-vassal relationship; the feudalism was more like tribalism and clans than the European model, but with Confucianism layered on top.

So when E.O. Wilson, still intellectually agile in his twilight years, describes the divide between kin selection and multi-level selection in the New York Times, we start to see a similar pattern of explanation for both models at far more basic level than just in the happenstances of Chinese versus European cultures. Kin selection predicts that genetic co-representation can lead an individual to self-sacrifice in an evolutionary sense (from loss of breeding possibilities in Hymenoptera like bees and ants, through to sacrificial behavior like standing watch against predators and thus becoming a target, too). This is the traditional explanation and the one that fits well for the Chinese model. But we also have the multi-level selection model that posits that selection operates at the group level, too. In kin selection there is no good explanation for the European feudal tradition unless the vassals are inbred with their lords, which seems unlikely in such a large, diverse cohort. Consolidating power among the lords and intermarrying practices possibly did result in inbreeding depression later on, but the overall model was one based on social ties that were not based on genetic familiarity.… Read the rest

Novelty and the Novel

Mark DavisLeave a comment

stillsuitMy 14-year-old is obsessed with Frank Herbert’s Dune right now, marveling over the complexity and otherworldly ornamentation that Herbert imbued in his strange hyper-future (or past maybe, who knows). Dune might read as an allegory about Middle Eastern oil or about psychotropic drugs or nothing at all, but regardless of any deeper layers in its palimpsest,  it is so surprising to a first reader—especially a young one—that it still has the power to fuel daydreams (I obsessed over building a stillsuit at my son’s age, imagining being able to spend days in the harsh New Mexico summer without the need for water).

So it may be surprising that I found myself agreeing with Ian McEwan in The New Republic where he calls into doubt the validity of fiction, though ultimately he rediscovers his love of fiction in Nabakov’s “Caress [of the] divine details” and in John Updike’s controlled descriptions. He comes back again to fiction but not at the expense of wanting nonfiction that brings him new ideas. We are information harvesting machines and the novelty generation rate of nonfiction (there is always the history you do not know much less the cosmology you can’t understand) is just much greater than that of fiction.

But perhaps there is a détente in the middle where fiction and nonfiction commingle. The historical novel is perhaps the best example. The only fear being that the history is too much bent to the requirements of drama and conflict to be at all accurate. Likewise, there might be modern hard science fiction that provides an accurate and deep glimpse into the hermeneutics of real scientific research, and possible scientific futures. Then, at least, there is information beyond the craft of writing embedded within them.… Read the rest

A Paradigm of Guessing

Mark DavisLeave a comment

boxesThe most interesting thing I’ve read this week comes from Jurgen Schmidhuber’s paper, Algorithmic Theories of Everything, which should be provocative enough to pique the most jaded of interests. And the quote is from way into the paper:

The first number is 2, the second is 4, the third is 6, the fourth is 8. What is the fifth? The correct answer is “250,” because the nth number is n 5 −5n^4 −15n^3 + 125n^2 −224n+ 120. In certain IQ tests, however, the answer “250” will not yield maximal score, because it does not seem to be the “simplest” answer consistent with the data (compare [73]). And physicists and others favor “simple” explanations of observations.

And this is the beginning and the end of logical positivism. How can we assign truth to inductive judgments without crossing from fact to value, and what should that value system be?… Read the rest

The Churches of Evil

Mark DavisLeave a comment

The New York Times continues to mine the dark territory between religious belief and atheism in a series of articles in the opinion section, with the most recent being Gary Cutting’s thoughtful meditation on agnosticism, ways of knowing, and the contributions of religion to individual lives and society. In response, Penn Jillette and others discuss atheism as a religion-like venture.

We can dissect Cutting’s argument while still being generous to his overall thrust. It is certainly true that aside from the specific knowledge claims of religious people that there are traditions of practice that result in positive outcomes for religious folk. But when we drill into the knowledge dimension, Cutting props up Alvin Plantinga and Richard Swinburne as representing “the role of evidence and argument” in advanced religious argument. He might have been better to restrict the statement to “argument” in this case, because both philosophers focus primarily on argument in their philosophical works. So evidence remains elusively private in the eyes of the believer.

Interestingly, many of the arguments of both are simply arguments against a counter-assumption that anticipates a secular universe. For instance, Plantinga shows that the Logical Problem of Evil is not incoherent, resulting in a conclusion that evil (neglect “natural evil” for the moment) is not logically incompatible with omnibenevolence, omnipotence, and omniscience. But, and here we get back to Cutting, it does nothing to persuade us that the rapacious cruelty of Yahweh much less the moral evil expressed in the new concept of Hell in the New Testament are anything more than logically possible. The human dimension and the appropriate moral outrage are unabated and we loop back to the generosity of Cutting towards the religious: shouldn’t we provide equal generosity to the scriptural problem of evil as expressed in everything from the Hebrew Bible through to the Book of Mormon?… Read the rest

Teleology, Chapter 12

Mark DavisLeave a comment

Everything is prediction. Compression is truth. Teleonomy is the new teleology. I’m working on wondermentation. It is of arguable utility to create pithy little epigrams and nonce phrases as markers to different phases of one’s life, but they began to accumulate as graduate school ground down towards a soft landing at Stanford. My studies and research started to get lively towards the end of my undergrad degree with an assistanceship in the Advanced Computing Laboratory. Machine learning and evolutionary computation were my favored areas of interest and I supported my core studies with evolutionary biology, ethology, analytic philosophy and mathematics.

I felt I had crossed a Rubicon late in my senior year at Cornell as I worked on a fundamental challenge in learning patterns directly from data—so-called unsupervised learning and knowledge acquisition. The problem posed as a kind of Manichaean mystery to me, divided between treating every single data point as a singularity and similarly considering them all as a unified whole. Between the two poles was compromise meted out by co-occurrence priorities; events close together in time and space deserved capture as a statistical regularity.

The threshold question was what form that acquisition algorithm could take on that would lead to an efficient coding of the data into a predictive model. The answer was found in an elliptical foray through the fundamentals of mathematics and computing, then straight into the heart of evolutionary thinking. I did not really emerge from it, either. There was a small eureka moment with a gradual fading of interest as summer hit and I was back in Santa Fe after graduating, waiting for my Masters program to kick-off. It stayed with me and I carried a small notebook around, feverishly scribbling notes while once again wandering up those arroyos towards the ruddy canyons above.… Read the rest

Ye Olde Leaden New Year
