Rationality and the Intelligibility of Philosophy

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

Non-Cognitivist Trajectories in Moral Subjectivism

imageWhen I say that “greed is not good” the everyday mind creates a series of images and references, from Gordon Gekko’s inverse proposition to general feelings about inequality and our complex motivations as people. There is a network of feelings and, perhaps, some facts that might be recalled or searched for to justify the position. As a moral claim, though, it might most easily be considered connotative rather than cognitive in that it suggests a collection of secondary emotional expressions and networks of ideas that support or deny it.

I mention this (and the theories that are consonant with this kind of reasoning are called non-cognitivist and, variously, emotive and expressive), because there is a very real tendency to reduce moral ideas to objective versus subjective, especially in atheist-theist debates. I recently watched one such debate between Matt Dillahunty and an orthodox priest where the standard litany revolved around claims about objectivity versus subjectivity of truth. Objectivity of truth is often portrayed as something like, “without God there is no basis for morality. God provides moral absolutes. Therefore atheists are immoral.” The atheists inevitably reply that the scriptural God is a horrific demon who slaughters His creation and condones slavery and other ideas that are morally repugnant to the modern mind. And then the religious descend into what might be called “advanced apologetics” that try to diminish, contextualize, or dismiss such objections.

But we are fairly certain regardless of the tradition that there are inevitable nuances to any kind of moral structure. Thou shalt not kill gets revised to thou shalt not murder. So we have to parse manslaughter in pursuit of a greater good against any rules-based approach to such a simplistic commandment.… Read the rest

A Critique of Pure Randomness

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

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

On Killing Kids

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

Language Games

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

Humbly Evolving in a Non-Simulated Universe

darwin-changeThe New York Times seems to be catching up to me, first with an interview of Alvin Plantinga by Gary Cutting in The Stone on February 9th, and then with notes on Bostrom’s Simulation Hypothesis in the Sunday Times.

I didn’t see anything new in the Plantinga interview, but reviewed my previous argument that adaptive fidelity combined with adaptive plasticity must raise the probability of rationality at a rate that is much greater than the contributions that would be “deceptive” or even mildly cognitively or perceptually biased. Worth reading is Branden Fitelsen and Eliot Sober’s very detailed analysis of Plantinga’s Evolutionary Argument Against Naturalism (EAAN), here. Most interesting are the beginning paragraphs of Section 3, which I reproduce here because it is a critical addition that should surprise no one but often does:

Although Plantinga’s arguments don’t work, he has raised a question that needs to be answered by people who believe evolutionary theory and who also believe that this theory says that our cognitive abilities are in various ways imperfect. Evolutionary theory does say that a device that is reliable in the environment in which it evolved may be highly unreliable when used in a novel environment. It is perfectly possible that our mental machinery should work well on simple perceptual tasks, but be much less reliable when applied to theoretical matters. We hasten to add that this is possible, not inevitable. It may be that the cognitive procedures that work well in one domain also work well in another; Modus Ponens may be useful for avoiding tigers and for doing quantum physics.

Anyhow, if evolutionary theory does say that our ability to theorize about the world is apt to be rather unreliable, how are evolutionists to apply this point to their own theoretical beliefs, including their belief in evolution?

Instrumenting Others

slave-marketJerry Coyne takes down Ross Douthat’s New York Times column in The New Republic along multiple dimensions, but perhaps the most interesting one is his draw-down of the question of what exactly Christian morality amounts to? We can equally question any other religious morality or even secular ones.

For instance, we mostly agree that slavery is a bad idea in the modern world. Slavery involves treating others instrumentally, using them for selfish outcomes, and exploiting their human capacity. Slavery is almost unquestionable; it lacks many of the conventional ambiguities that dominate controversial social issues. Yet slavery was quite acceptable in the Old Testament, with the only relief coming for the enslavement of Jews by Jews with the release of the slaves after six years (under certain circumstances). Literal interpretations of the Bible resort to expansive apologetics to try to minimize these kinds of problems, but they are just the finer chantilly skimmed off human sacrifice, oppression, and genocide.

So how do people make moral choices? They only occasionally invoke religious sentiments or ideas even when they are believers, though they may often articulate a claim of prayer or meditation. Instead, the predominant moral calculus is girded by modern ideas and conflicts that are evolving faster than even generational change. Pot is OK, gay marriage is just a question of equality, and miscegenation is none of our business. Note that only the second item has a clear reference point in JCM (Judeo-Christian-Muslim) scripture. The others might get some traction using expansive interpretations, but those are expansive interpretations that just justify my central thesis that moral decision-making is really underdetermined by religious thinking (or even formal philosophical ones). Moral decision making is determined by knowledge and education in an ad hoc way that relies on empathic and intellectual reasoning.… Read the rest

The Churches of Evil

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

SOOO or OOO

An ever-present flaw in almost all theology and apologetics–and a flaw that is easily remediable–is the requirement for omnipotence, omnibenevolence, and omniscience (OOO) on the part of the structure of God or the gods. We see this in the argumentative doldrums of the Problem of Evil, with practitioners like William Lane Craig and Richard Swinburne building-out elaborate explanatory theodicies in an effort to justify or, at least, allow for an OOO deity. There are extensional consequences, too, like Paul Draper’s argument that an OOO-deity may be obligated to create more than just a single worshipful species given the known extent of the universe.

And what if we remedy the flaw by simply declaring that the OOO assumptions are unnecessary for deities? What if we simply loosen the requirement to something like “God is super-powerful and super-good?” Let’s call this the semi-OOO god theory or SOOO for short. Does SOOO short-circuit the most problematic issues that arise in placing the gods so far above us that we no longer resemble them at all? (an interesting side note: given Christianity’s obsession with the avatar-like character of Christ, it hardly seems aesthetically wrong to assume a flawed God).

The theological and apologetic problems do seem to evaporate, though philosophical arguments evaporate, too:

  • The Ontological Argument: The premise requiring God to be the greatest possible being (Anselmian formulation) immediately goes away. Therefore, there is no Ontological Argument. God doesn’t exist, but only on the initial premise. God may still exist as an SOOO deity.
  • The Cosmological Argument: No impact; the First Cause could be just about anything, as before. Only pre-scientific societies necessarily associate such a cause with an OOO deity.
  • The Problem of Evil: There are actually many formulations of the Problem of Evil, and it remains debated to this day, yet the primary formulation currently fashionable among apologists requires evil (at least moral evil, but sometimes also “natural” evil) in order to provide a proving ground for our moral character.
