Desire and Other Matters

Mark DavisLeave a comment

“What matters?” is a surprisingly interesting question. I think about it constantly since it weighs-in whenever plotting future choices, though often I seem to be more autopilot than consequentialist in these conceptions. It is an essential first consideration when trying to value one option versus another. I can narrow the question a bit to “what ideas matter?” This immediately externalizes the broad reality of actions that meaningfully improve lives, like helping others, but still leaves a solid core of concepts that are valued more abstractly. Does the traditional Western liberal tradition really matter? Do social theories? Are less intellectually-embellished virtues like consistency and trust more relevant and applicable than notions like, well, consequentialism?

Maybe it amounts to how to value certain intellectual systems against others?

Some are obviously more true than others. So “dowsing belief systems” are less effective in a certain sense than “planetary science belief systems.” Yet there are a broader range of issues at work.

But there are some areas of the liberal arts that have a vexing relationship with the modern mind. Take linguistics. The field ranges from catalogers of disappearing languages to theorists concerned with how to structure syntactic trees. Among the latter are the linguists who have followed Noam Chomsky’s paradigm that explains language using a hierarchy of formal syntactic systems, all of which feature recursion as a central feature. What is interesting is that there have been very few impacts of this theory. It is very simple at its surface: languages are all alike and involve phrasal groups that embed in deep hierarchies. The specific ways in which the phrases and their relative embeddings take place may differ among languages, but they are alike in this abstract way.… Read the rest

Subtly Motivating Reasoning

Mark DavisLeave a comment

larson-sheepContinuing on with the general theme of motivated reasoning, there are some rather interesting results reported in New Republic, here. Specifically, Ian Anson from University of Maryland, Baltimore County, found that political partisans reinforced their perspectives on the state of the U.S. economy more strongly when they were given “just the facts” rather than a strong partisan statement combined with the facts. Even when the partisan statements aligned with their own partisan perspectives, the effect held.

The author concludes that people, in constructing their views of the causal drivers of the economy, believe that they are unbiased in their understanding of the underlying mechanisms. The barefaced partisan statements interrupt that construction process, perhaps, or at least distract from it. Dr. Anson points out that subtly manufacturing consent therefore makes for better partisan fellow travelers.

There are a number of theories concerning how meanings must get incorporated into our semantic systems, and whether the idea of meaning itself is as good or worse than simply discussing reference. More, we can rate or gauge the uncertainty we must have concerning complex systems. They seem to form a hierarchy, with actors in our daily lives and the motivations of those we have long histories with in the mostly-predictable camp. Next we may have good knowledge about a field or area of interest that we have been trained in. When this framework has a scientific basis, we also rate our knowledge as largely reliable, but we also know the limits of that knowledge. It is in predictive futures and large-scale policy that we become subject to the difficulty of integrating complex signals into a cohesive framework. The partisans supply factoids and surround them with causal reasoning.… Read the rest

Euhemerus and the Bullshit Artist

Mark DavisLeave a comment

trump-minotaurSailing 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.

Motivation, Boredom, and Problem Solving

Mark DavisLeave a comment

shatteredIn the New York Times Stone column, James Blachowicz of Loyola challenges the assumption that the scientific method is uniquely distinguishable from other ways of thinking and problem solving we regularly employ. In his example, he lays out how writing poetry involves some kind of alignment of words that conform to the requirements of the poem. Whether actively aware of the process or not, the poet is solving constraint satisfaction problems concerning formal requirements like meter and structure, linguistic problems like parts-of-speech and grammar, semantic problems concerning meaning, and pragmatic problems like referential extension and symbolism. Scientists do the same kinds of things in fitting a theory to data. And, in Blachowicz’s analysis, there is no special distinction between scientific method and other creative methods like the composition of poetry.

We can easily see how this extends to ideas like musical composition and, indeed, extends with even more constraints that range from formal through to possibly the neuropsychology of sound. I say “possibly” because there remains uncertainty on how much nurture versus nature is involved in the brain’s reaction to sounds and music.

In terms of a computational model of this creative process, if we presume that there is an objective function that governs possible fits to the given problem constraints, then we can clearly optimize towards a maximum fit. For many of the constraints there are, however, discrete parameterizations (which part of speech? which word?) that are not like curve fitting to scientific data. In fairness, discrete parameters occur there, too, especially in meta-analyses of broad theoretical possibilities (Quantum loop gravity vs. string theory? What will we tell the children?) The discrete parameterizations blow up the search space with their combinatorics, demonstrating on the one hand why we are so damned amazing, and on the other hand why a controlled randomization method like evolutionary epistemology’s blind search and selective retention gives us potential traction in the face of this curse of dimensionality.… Read the rest

Quantum Field Is-Oughts

Mark DavisLeave a comment

teleologySean Carroll’s Oxford lecture on Poetic Naturalism is worth watching (below). In many ways it just reiterates several common themes. First, it reinforces the is-ought barrier between values and observations about the natural world. It does so with particular depth, though, by identifying how coarse-grained theories at different levels of explanation can be equally compatible with quantum field theory. Second, and related, he shows how entropy is an emergent property of atomic theory and the interactions of quantum fields (that we think of as particles much of the time) and, importantly, that we can project the same notion of boundary conditions that result in entropy into the future resulting in a kind of effective teleology. That is, there can be some boundary conditions for the evolution of large-scale particle systems that form into configurations that we can label purposeful or purposeful-like. I still like the term “teleonomy” to describe this alternative notion, but the language largely doesn’t matter except as an educational and distinguishing tool against the semantic embeddings of old scholastic monks.

Finally, the poetry aspect resolves in value theories of the world. Many are compatible with descriptive theories, and our resolution of them is through opinion, reason, communications, and, yes, violence and war. There is no monopoly of policy theories, religious claims, or idealizations that hold sway. Instead we have interests and collective movements, and the above, all working together to define our moral frontiers.

Rationality and the Intelligibility of Philosophy

Mark DavisLeave a comment

6a00d83542d51e69e20133f5650edd970b-800wiThere is a pervasive meme in the physics community that holds as follows: there are many physical phenomena that don’t correspond in any easy way to our ordinary experiences of life on earth. We have wave-particle duality wherein things behave like waves sometimes and particles other times. We have simultaneous entanglement of physically distant things. We have quantum indeterminacy and the emergence of stuff out of nothing. The tiny world looks like some kind of strange hologram with bits connected together by virtual strings. We have a universe that began out of nothing and that begat time itself. It is, in this framework, worthwhile to recognize that our every day experiences are not necessarily useful (and are often confounding) when trying to understand the deep new worlds of quantum and relativistic physics.

And so it is worthwhile to ask whether many of the “rational” queries that have been made down through time have any intelligible meaning given our modern understanding of the cosmos. For instance, if we were to state the premise “all things are either contingent or necessary” that underlies a poor form of the Kalam Cosmological Argument, we can immediately question the premise itself. And a failed premise leads to a failed syllogism. Maybe the entanglement of different things is piece-part of the entanglement of large-scale space time, and that the insights we have so far are merely shadows of the real processes acting behind the scenes? Who knows what happened before the Big Bang?

In other words, do the manipulations of logic and the assumptions built into the terms lead us to empty and destructive conclusions? There is no reason not to suspect that and therefore the bits of rationality that don’t derive from empirical results are immediately suspect.… Read the rest

A Critique of Pure Randomness

Mark DavisLeave a comment

Random MemeThe notion of randomness brings about many interesting considerations. For statisticians, randomness is a series of events with chances that are governed by a distribution function. In everyday parlance, equally-likely means random, while an even more common semantics is based on both how unlikely and how unmotivated an event might be (“That was soooo random!”) In physics, there are only certain physical phenomena that can be said to be truly random, including the probability of a given nucleus decomposing into other nuclei via fission. The exact position of a quantum thingy is equally random when it’s momentum is nailed down, and vice-versa. Vacuums have a certain chance of spontaneously creating matter, too, and that chance appears to be perfectly random. In algorithmic information theory, a random sequence of bits is a sequence that can’t be represented by a smaller descriptive algorithm–it is incompressible. Strangely enough, we simulate random number generators using a compact algorithm that has a complicated series of steps that lead to an almost impossible to follow trajectory through a deterministic space of possibilities; it’s acceptible to be random enough that the algorithm parameters can’t be easily reverse engineered and the next “random” number guessed.

One area where we often speak of randomness is in biological evolution. Random mutations lead to change and to deleterious effects like dead-end evolutionary experiments. Or so we hypothesized. The exact mechanism of the transmission of inheritance and of mutations were unknown to Darwin, but soon in the evolutionary synthesis notions like random genetic drift and the role of ionizing radiation and other external factors became exciting candidates for the explanation of the variation required for evolution to function. Amusingly, arguing largely from a stance that might be called a fallacy of incredulity, creationists have often seized on a logical disconnect they perceive between the appearance of purpose both in our lives and in the mechanisms of biological existence, and the assumption of underlying randomness and non-directedness as evidence for the paucity of arguments from randomness.… Read the rest

The Rise and Triumph of the Bayesian Toolshed

Mark DavisLeave a comment

Bayes LawIn 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

Language Games

Mark Davis6 Comments

Word GamesOn The Thinking Atheist, C.J. Werleman promotes the idea that atheists can’t be Republicans based on his new book. Why? Well, for C.J. it’s because the current Republican platform is not grounded in any kind of factual reality. Supply-side economics, Libertarianism, economic stimuli vs. inflation, Iraqi WMDs, Laffer curves, climate change denial—all are grease for the wheels of a fantastical alternative reality where macho small businessmen lift all boats with their steely gaze, the earth is forever resilient to our plunder, and simple truths trump obscurantist science. Watch out for the reality-based community!

Is politics essentially religion in that it depends on ideology not grounded in reality, spearheaded by ideologues who serve as priests for building policy frameworks?

Likely. But we don’t really seem to base our daily interactions on rationality either. 538 Science tells us that it has taken decades to arrive at the conclusion that vitamin supplements are probably of little use to those of us lucky enough to live in the developed world. Before that we latched onto indirect signaling about vitamin C, E, D, B12, and others to decide how to proceed. The thinking typically took on familiar patterns: someone heard or read that vitamin X is good for us/I’m skeptical/why not?/maybe there are negative side-effects/it’s expensive anyway/forget it. The language games are at all levels in promoting, doubting, processing, and reinforcing the microclaims for each option. We embrace signals about differences and nuances but it often takes many months and collections of those signals in order to make up our minds. And then we change them again.

Among the well educated, I’ve variously heard the wildest claims about the effectiveness of chiropractors, pseudoscientific remedies, the role of immunizations in autism (not due to preservatives in this instance; due to immune responses themselves), and how karma works in software development practice.… Read the rest
