Imagining Transparent Iron and Other Crazy Things

Mark Davis1 Comment

There are some real doozies of arguments that have tied up religious and philosophical thinkers for centuries. Take the Kalam Cosmological Argument or the Ontological Argument. In both of these arguments there is a required reduction of the properties of the universe (or cosmos) to some kind of skeletal representation. In Kalam (and variants) there are assumptions built into the idea of nothingness, for instance, that have no relationship to what we know about the actual cosmos now—specifically that there is no example of such a thing; even in vacuums there are pervasive quantum fields and we have no clear scientific evidence or theories that point to a “philosopher’s nothingness.” In the Ontological Argument, there is the assumption that possibility and existence are inherently combined together, regardless of whether we are talking about a concept of God or a real thing in or supporting the existence of the cosmos. Another example of this philosophical craziness is in the modal argument for the existence of philosophical zombies, where there are people just like us in every way but lacking a phenomenal experience of being conscious beings.

There is a category of thought called “modal skepticism” that argues we should be cautious about making assumptions about things extremely outside of ordinary experience. Whether it’s the properties of gods or nothingness or consciousness, the trouble arises when trying to sketch out the properties that apply to these things. Even before modal logic in its modern form, Kant argued that existence is not a predicate and therefore the existence of God can’t be contained in an a priori definition of God. We are making an incorrect assumption. In Kalam, nothingness is not definable in a way that meaningfully separates it from a posteriori discoveries about the cosmos, where it does not seem to exist.… Read the rest

All Hail Evolved Irrationality

Mark DavisLeave a comment

From an impersonal distance, watching other people make decisions is always interesting. They may apply reason and passion in varied measures to figure out a way forward, or a lifestyle, or even fashion choices. Often they mindfully weigh the choices and decide to moderate even that process, committing to a radical path that has drama and uncertainty. It’s sometimes better to be interesting than cautious and correct. As a virtue this recalls the romantic movements that arose in opposition to the mechanization of the 19th century as trains and steamships criss-crossed the world. Order and peace were at odds with drama, passion, faith, and love that are somehow in our core, animalistic nature.

Motifs of uncertainty crept into science and reason as we transitioned into the 20th century, from the stochastic rumble of thermodynamics, to the realigning of basic concepts like gravity as a space-time curvature, and then the wave-particle duality of quantum reality. The clockwork of the universe that was so oppressively mechanistic showed fuzzy edges and knotty intersections that defied ordinary-scale expectations. The combined mathematical realizations of incompleteness and algorithmic uncomputability overlaid the investigations of the physical to such an extent that new theories were developed that proposed that the quantum world and mind are inextricably laced together; subjective and objective do not exist independently.

Even as our knowledge and management of the universe has grown, there is a background roil of irrationality, like the primal chaos of Tiamat. Human thought has a collection of ways of organizing the world that appear to be natural consequences of our social development. Religious belief is a widespread catalyst for building predictable and supportive communities by slaving our baser tendencies to coordinating strictures, obligations, and status maintenance.… Read the rest

Incredulity as a Moral Failure

Mark Davis4 Comments

I keep encountering arguments from incredulity in the speculative religious community. An argument from incredulity is just an assertion by the arguer that they can’t imagine how something is possible. In two recent examples, the arguers are the Christian faithful and are trying to deconstruct materialist counterarguments to their speculations about collections of facts. I think this is both an intellectual and a moral failure. It is an intellectual failure when the speculators don’t choose the obvious stance with regard to unknowns and unknowables: I don’t know. It is a moral failure when the consequences of such intellectual failures leads to weakly-justifiable faith constructs that harm or might harm others.

Let’s take a couple of examples. First, we have Ross Douthat (I know, I know, I spend too much time on him, but he does have a big platform being at New York Times). He has a forthcoming book about why one should believe in a religion, although he is not forceful about which particular one is the right choice for any individual, it seems. But here is a recent set of three arguments from that book. They all rely on incredulity in some way.

  1. The fine tuning argument. Ross thinks it is highly improbable that some physical constants in our universe happened by chance. He also thinks that one materialist solution to that happenstance is to speculate about multiverses. In the multiverse solution, there are many universes (maybe a cosmic foam with little universe bubbles!) and ours just happened to be goldilocksish for the structure we observe. Of course, we can speculate all day about this. We can instead say perhaps we have been having infinite Big Bangs as a single universe expands then collapses.

Time, Consciousness, and Joy in 2025

Mark Davis2 Comments

A glorious 2025 comes roaring in despite the nastiness of contemporary American and (some) worldwide politics. Everyone’s angry, despite the ingenious control of murderous pathogens, the brilliant performance of the post-COVID economic recovery in the United States, dropping crime rates, and the continued progress on reducing and eliminating worldwide poverty. But these are aggregate measures of social and scientific success and far too many individuals remain discontented with their own status and fears that social forces beyond their control are limiting their success and happiness.

In this, one must be circumspect: reading out stats that contradict the mood is not reading the room. So, instead, I try to focus on unexpected innovations that lead us to defocus on our own situational context and instead find a larger reimagining. This is a modern therapy that isn’t dismissive of the effectiveness of our highly successful institutions of scientific achievement, peace-preserving world orders, and liberal democracies that effectively balance individual freedoms against order. It’s a celebration of them, instead.

I give you two new joys as the new year starts to build. First, we have the novel realization that dark energy and matter might be better explained by relativistic distortions of space-time in the universe based on the quantities of matter in denser versus void-like areas of space. Here’s Anton Petrov with a primer:

This certainly simplifies things if true, but it needs to be observationally verified and reconsidered if it doesn’t pan out. There’s that underlying joy in science: everything is tentative because we are all flawed.

The second development changes from an external focus on the monumental scale of the universe to something much more human. I’ve previously covered the curious theory of quantum consciousness proposed by Roger Penrose and Stuart Hameroff, but there have been some recent developments.… 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

Be Persistent and Evolve

Mark DavisLeave a comment

If we think about the evolution of living things we generally start from the idea that evolution requires replicators, variation, and selection. But what if we loosened that up to the more everyday semantics of the word “evolution” when we talk about the evolution of galaxies or of societies or of crystals? Each changes, grows, contracts, and has some kind of persistence that is mediated by a range of internal and external forces. For crystals, the availability of heat and access to the necessary chemicals is key. For galaxies, elements and gravity and nuclear forces are paramount. In societies, technological invention and social revolution overlay the human replicators and their biological evolution. Should we make a leap and just declare that there is some kind of impetus or law to the universe such that when there are composable subsystems and composition constraints, there will be an exploration of the allowed state space for composition? Does this add to our understanding of the universe?

Wong, et. al. say exactly that in “On the roles of function and selection in evolving systems” in PNAS. The paper reminds me of the various efforts to explain genetic information growth given raw conceptions of entropy and, indeed, some of those papers appear in the cites. It was once considered an intriguing problem how organisms become increasingly complex in the face of, well, the grinding dissolution of entropy. It wasn’t really that hard for most scientists: Earth receives an enormous load of solar energy that supports the push of informational systems towards negentropy. But, to the earlier point about composability and constraints, the energy is in a proportion that supports the persistence of systems that are complex.… Read the rest

Contrasts and Failures, Hope and Awe

Mark Davis2 Comments

Russell Moore writes in the Atlantic that American evangelicalism is in crisis. There is a Faustian pact of unholy MAGA politics, conspiracy theories, and religious feelings that can only be remedied with a revival of the faith itself, laser-focused on Moore’s conceptions of what Christianity should strive to become. He acknowledges that there is a dark history to America’s evangelical movement through the 20th century. It was always political in close focus, with the maintenance of racism and exclusion at its core well before abortion was even a talking point. Anti-Catholicism and antisemitism were equally bundled up with the evangelical mindset. Beyond the moral failings that sloshed into politics, there was the structural marketing of the faith by televangelists and traveling ministries that turned the hoped-for internal conversion into a more cynical plot:

In the end, a market-driven religion gives rise to a market-driven approach to truth, and this development ultimately eviscerated conservative Christianity in the US and left it the possession of hypocrites and hucksters.

I’m not at all surprised. As information has become unlocked from the vaults of academic pursuits by modern technologies, the ripples of uncertainty about faith claims have spread and clashed with the desire to totalize the political, personal, pragmatic, and moral dimensions of evangelical beliefs. If a thing is so unquestionably right and good, it must infiltrate and own the mind, the body, the soul, the community, and the nation. So why is the world drifting away, seemingly inexorably?

But even those who leave their faith communities feel adrift, clinging to vague spirituality or buffet gorging across traditions in search of something that is satisfactory but different. But that is only in the best of moments, when a song triggers nostalgia or late after eggnog on Christmas Eve.… 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
