Deep Zombies

Mark Davis1 Comment

There is a slang nominal form of the word “deepening” for when a person seems to be purposefully adding awe, mystery, and unknowns to their arguments: deepenings. It often arises in discourse on religion and mystical experiences. As a child in the 70s we had Bigfoot, Nessy, the Bermuda Triangle, UFOs, near-death experiences, and the strange stuff from Velikovsky, von Däniken, and Sitchin. The books and movies built deepenings into communities and businesses just as surely as Catholicism, Mormonism, or Scientology have done. There is a human desire for mystery. But it doesn’t make the mysteries true. But many religious folks hold on to thin threads that point towards mystery as an added data point for justifying their faiths as real, true, valuable, and beautiful.

Given this, I was curious about David Bentley Hart’s All Things are Gods: The Mysteries of Mind and Life after Ross Douthat praised it at New York Times. It’s a big book and I’ve just skimmed around a fair bit so far, but there is a repetition of an error (among the extensive repetitions in the volume) concerning the mind-body problem that is also related to arguments from Alvin Plantinga concerning evolution. Specifically, the notion of philosophical zombies is largely irrelevant I think to claiming that subjective experience (“what it’s like…”) is non-material or of a distinct nature from the brain and the nervous system. Given what we know about evolutionary development, I don’t think that we can even conceive of a p-zombie in the way it was originally proposed.

We might try to imagine an evolutionary development of homo sapiens that does not include this subjective experience, but that would not lead to an identical human sans the qualia-experiencer because the developmental trajectory would have to be different, resulting in differing brains.… Read the rest

Rise, Teleonomatons!

My essay for the Berggruen Prize this year. Of course, the organization missed an opportunity to drop down a staggering rabbit hole and lean into a whole new regime of neologistic energetics, but I do like the prize-winning essays!

Meaning entanglements

I can’t figure out what some statements about science mean, though I have a fair background in a range of scientific areas. Now, I can peruse highly technical papers, browse abstracts, interpret graphs, study conclusions, and typically do just fine. The professional stuff is a procession of arid facts and assumes the reader knows the basic definitions for things. It’s the popular versions of scientific insights that befuddle me—especially the definitions that try mightily to bridge meanings for learners. So do introductory texts. Light is a wave? Not exactly. Atoms are particles? Well, not quite, but they are small. Electrons orbit the nucleus? No, really, no. A force is an influence tending to change the motion of a body? OK, but what is an influence? People are influenced, aren’t they? Or under the influence.

And then there are texts like those of existential philosophers that leave me completely befuddled. What is this “Being” that they write about and how did it get so enlarged in significance, capitalized, and shoehorned by the translator into incomprehensible juxtapositions with other bulbous words?

It may be low pedantry to expect clarity from words and writing. We generally just roll with it and use the terms according to conventions inferred from reading and learning. We rush over the imperfect metaphorical bridges, the analogies, the similes. For physics, definitions are bound to the equations and measurement properties that accompany the words of description, and they become a semantic pier that is constantly informing our relationship with the ideas.… Read the rest

Causally Emergent vs. Divine Spark Murder Otherwises

Mark DavisLeave a comment

One might claim that a metaphysical commitment to strong determinism is only porous to quantum indeterminacy or atomic indeterminacy (decay behavior for instance). Those two can be lumped together and simply called subatomic indeterminacy or something. Everything else is conceptually derivative of state evolution and therefore deterministic. So does that mean that my model for R fails unless I can invoke these two candidates? My suggestion of amplifying thermodynamic noise doesn’t really cut the mustard (an amusing semantic drift from pass muster, perhaps) because it only appears random and solely characterizable by these macroscopic variables like pressure and temperature, not because it actually is random in the molecule swirl.

But I can substitute an atomic decay counter for my thermodynamic amplifier, or use a quantum random number generator based on laser measurements of vacuum fluctuations. There, I’ve righted the ship, though I’ve jettisoned my previous claim that randomness is not necessary for R’s otherwises. Now it is, but it is not sufficient because of the need for a device like the generative subsystem that uses randomness in a non-arbitrary way to revise decisions. We do encounter a difficulty in porting subatomic indeterminacy into a human analog, of course, though some have given it a try.

But there is some new mathematics for causal emergence that fits well with my model. In causal emergence, ideas like necessity and sufficiency for causal explanations can be shown to have properties in macroscale explanations that are not present at microscales. The model used is a simple Markov chain that flips between two states and information theory is applied to examine a range of conceptual structures for causation running from David Hume’s train of repeating objects (when one damn thing comes after another and then again and again, we may have a cause), up through David Lewis’s notion of counterfactuals in alternative probabilistic universes (could it have happened that way in all possible worlds?),… Read the rest

Indeterminacy and the Ethics of Emergence

Mark DavisLeave a comment

Continuing on with this theme of an ethics of emergence, can we formulate something interesting that does better than just assert that freedom and coordination are inherent virtues in this new scheme? And what does that mean anyway in the dirty details? We certainly see natural, emergent systems that exhibit tight regulatory control where stability, equilibrium, and homeostasis prevent dissipation, like those hoped-for fascist organismic states. There is not much free about these lower level systems, but we think that though they are necessary they are insufficient for the higher-order challenges of a statistically uncertain world. And that uncertainty is what drives the emergence of control systems in the first place. The control breaks out at some level, though, in a kind of teleomatic inspiration, and applies stochastic exploration of the adaptive landscape. Freedom then arises as an additional control level, emergent itself.

We also have this lurking possibility that emergent systems may not be explainable in the same manner that we have come to expect scientific theories to work. Being highly contingent they can only be explained in specificity about their contingent emergence, not by these elegant little explanatory theories that we have now in fields like physics. Stephen Wolfram, and the Santa Fe Institute folks as well, investigated this idea but it has remained inconclusive in its predictive power so far, though that may be changing.

There is an interesting alternative application for deep learning models and, more generally, the application of enormous simulation systems: when emergent complexity is daunting, use simulation to uncover the spectrum of relationships that govern complex system behavior.

Can we apply that to this ethics or virtue system and gain insights from it?… Read the rest

When the Cranes Cry

Mark Davis1 Comment

The crane has a symbolic resonance in Celtic mythology. A magician, assuming an elaborate pose—one eye open and one leg drawn up—was said to see into the otherworld, just as the crane itself moved from sky to land to water. But there is the other meaning of the word crane: the ancient lifting contraption that helped build Greece and likely had a role in Egypt and Sumeria before that. And now they protrude into the urban sky, raising up our buildings and even other cranes as we densify our cities. It was this mechanical meaning that Dan Dennett at Tufts chose to contrast with conceptual skyhooks, the unsupported contrivances that save protagonists in plays by dangling gods above the stage. For Dennett, the building crane is the metaphor we should apply to the mindless, simple algorithm of evolution. The algorithm raises up species and thus creates our mysterious ideas about meaning and purpose. No skyhooks or Deus ex Machina are needed.

Dennett passed away at 82 in Maine leaving a legacy as a public intellectual who engaged in the pursuit of reason throughout his adult career. He was committed to the idea that this world—this teeming ensemble of living matter—is intrinsically miraculous, built up by something dead simple into all the convolutions and perilous ideas that we now use to parse its mysteries. He was one of the Four Horsemen of the Apocalypse during the so-called New Atheism craze of 2008-2010, along with Richard Dawkins, Christopher Hitchens, and Sam Harris, but even then he was committed to the crane metaphor to displace these ancient skyhooks of belief rather than, say, a satirical impact-analysis of religion a la Hitchens.

There is another phrase that Dennett championed in Darwin’s Dangerous Idea: Evolution and the Meanings of Life: universal acid.… Read the rest

Begging the Pseudo-Question

Mark Davis2 Comments

 

I recently got involved in an “audiophile” online discussion thread replete with devious trolling, commenter bans, incivility—the works. I do this from time to time because raucous argumentation forces one to think in tactical and strategic ways that are not the norm in everyday life. I also learn new things. In this case, I went on several quests, hunting down papers on the ability of Chinese language speakers to disambiguate tones in Gaussian noise, how distortion artifacts impact our perception of spatialization in binaural audio presentations, and even Rayleigh wave detection by sand scorpions (I actually worked on a simulator for that as a late undergrad). One of the key disagreements in the thread was over the notion of “science.” There were several perspectives on this, with the first one being that science requires experimentation and therefore using scientifically-derived tools for investigating the performance of audio equipment does not amount to science. This is obviously a shrugger and a distraction. The other primary perspective is always that science is in constant revision and there may be new insights that prove this-or-that subtle hearing capability since human hearing is just sooooo amazing. We are sooooo amazing.

There’s a bit of a Two Cultures-like tension in this universe of audio equipment aficionados: while engineering and science brings them audio gear, they want it to be poetic and ineffable and the work of mastery based in genius rather than Fast Fourier Transforms. Graphs are boring. Listening is beautiful.

Part of the reason for the disagreement is clearly that we just don’t have shared meanings about concepts like science. We circle around them and try to triangulate using metaphors, analogies, and explore the logical consequences of limits and extensions to their meaning.… Read the rest

The Rubbery Road from Original Position to Metaphysical Naturalism

Mark Davis1 Comment

From complaints about student protests over Israel in Gaza, to the morality of new House Speaker Johnson, and even to the reality and consequences of economic inequality, there is a dynamic conversation in the media over what is morally right and, importantly, why it should be considered right. It’s perfectly normal for those discussions and considered monologues to present ideas, cases, and weigh the consequences to American life, power, and the well-being of people around the world. It also demonstrates the fact that ideas like divine command theory become irrelevant for most if not all of these discussions since they still require secular analysis and resolution. Contributions from the Abrahamic faiths (and similarly from Hindu nationalism) are largely objectionable moral ideas (“The Chosen People,” jihad, anti-woman, etc.) that are inherently preferential and exclusionary.

Indeed, this public dialogue perhaps best shows how modern people build ethical systems. It looks mostly like Rawl’s concept of “reflective equilibrium” with dashes of utilitarianism and occasional influences from religious tradition and sentiment. And reflective equilibrium has few foundational ideas beyond a basic commitment to fairness as justice using the “original position” as its starting point. That is, if we had to create a society with no advance knowledge about what our role and position might be within it (a veil of ignorance), the best for us would be to create an equal, fair, and just society.

So ethics is cognitively rubbery, with changing attachments and valences as we process options into a coherent whole. We might justify civilian deaths for a greater good when we have few options, imprecise weapons, and existential fear (say, the atom bomb in World War II).… Read the rest

Oh, the Humanities!

Mark Davis1 Comment

I often laugh out loud at Ross Douthat’s New York Times columns that worry over strange spiritualisms taking over America, or try to unravel cultural knots that he always suggests might best be resolved by Catholicism (or even one of those lesser faiths), but I did enjoy his take today on the perishing of the humanities in America’s universities and colleges. I routinely read into the 18th and 19th centuries as an exploration of how language was once used. I read analytically, that is. Plots are picked apart. Characterization is considered. Clausal embedding is almost always more ornate than contemporary writing where such elaborations are pretentious or, at least, overwrought. I also (try to) read original versions of Balzac or Flaubert as an exercise in improving my French. What is less interesting to me are the class conflicts, racism, and gender roles from those bygone days. People are rotten enough today; I hardly need a reminder that we were always rotten and had reinforcing institutions and traditions overlaying that malaise.

But is there a threat to a decline in the participation in the humanities and a shift to STEM fields among university students? The argument is that it impacts our understanding of history and the drivers that got us here today. Perhaps it also diminishes our knowledge of logic and reason when philosophy is subtracted from the curriculum. Or just that the student never learns to articulate complex ideas and arguments.

An alternative to Douthat’s calls for monastic recitation and memorization as a grounding for the transmission of ideas is to make it more relevant to the STEM fields that have money and mindshare. In other words, inveigle the humanities into STEM; don’t fight, infiltrate.… Read the rest

Follow the Paths

Mark DavisLeave a comment

There is a little corner of philosophical inquiry that asks whether knowledge is justified based on all our other knowledge. This epistemological foundationalism rests on the concept that if we keep finding justifications for things we can literally get to the bottom of it all. So, for instance, if we ask why we think there is a planet called Earth, we can find reasons for that belief that go beyond just “’cause I know!” like “I sense the ground beneath my feet” and “I’ve learned empirically-verified facts about the planet during my education that have been validated by space missions.” Then, in turn, we need to justify the idea that empiricism is a valid way of attaining knowledge with something like, “It’s shown to be reliable over time.” This idea of reliability is certainly changing and variable, however, since scientific insights and theories have varied, depending on the domain in question and timeframe. And why should we in fact value our senses as being reliable (or mostly reliable) given what we know about hallucinations, apophenia, and optical illusions?

There is also a curious argument in philosophy that parallels this skepticism about the reliability of our perceptions, reason, and the “warrants” for our beliefs called the Evolutionary Argument Against Naturalism (EAAN). I’ve previously discussed some aspects of EAAN, but it is, amazingly, still discussed in academic circles. In a nutshell it asserts that our reliable reasoning can’t be evolved because evolution does not reliably deliver good, truthful ways of thinking about the world.

While it may seem obvious that the evolutionary algorithm does not deliver or guarantee completely reliable facilities for discerning true things from false things, the notion of epistemological pragmatism is a direct parallel to evolutionary search (as Fitelson and Sober hint).… Read the rest

Entanglements: Collected Short Works

Mark DavisLeave a comment

Now available in Kindle, softcover, and hardcover versions, Entanglements assembles a decade of short works by author, scientist, entrepreneur, and inventor Mark William Davis.

The fiction includes an intimate experimental triptych on the evolution of sexual identities. A genre-defying poetic meditation on creativity and environmental holocaust competes with conventional science fiction about quantum consciousness and virtual worlds. A postmodern interrogation of the intersection of storytelling and film rounds out the collected works as a counterpoint to an introductory dive into the ethics of altruism.

The nonfiction is divided into topics ranging from literary theory to philosophical concerns of religion, science, and artificial intelligence. Legal theories are magnified to examine the meaning of liberty and autonomy. A qualitative mathematics of free will is developed over the course of two essays and contextualized as part of the algorithm of evolution. What meaning really amounts to is always a central concern, whether discussing politics, culture, or ideas.

The works show the author’s own evolution in his thinking of our entanglement with reality as driven by underlying metaphors that transect science, reason, and society. For Davis, metaphors and the constellations of words that help frame them are the raw materials of thought, and their evolution and refinement is the central narrative of our growth as individuals in a webwork of societies and systems.

Entanglements is for readers who are in love with ideas and the networks of language that support and enervate them. It is a metalinguistic swim along a polychromatic reef of thought where fiction and nonfictional analysis coexist like coral and fish in a greater ecosystem.

Mark William Davis is the author of three dozen scientific papers and patents in cognitive science, search, machine translation, and even the structure of art.… Read the rest
