A Call for Papers: Mormon Thought and Engineering Vision

I am passing along the following announcement [official site]. My brief comments are below.

The Howard W. Hunter Chair of Mormon Studies in the School of Religion at Claremont Graduate University is pleased to sponsor a conference on:

Parallels and Convergences: Mormon Thought and Engineering Vision

Location:
Claremont Graduate University, 150 E. 10th Street, Claremont, CA 91711

Important Dates:
Abstract deadline: 2008 December 1 (extended abstract)
Conference: 2009 March 7 (Saturday)

Topics:
The Howard W Hunter Chair is interested in expanding the discussion of Latter-day Saint (LDS) perspectives on the attributes of God and the potential of man through a variety of innovative directions. One of the directions to be explored is whether there is a possible resonance between Mormon and engineering thought. The assumption is that according to LDS understanding, God is the architect of the Creation and the engineer of our bodies and spirits. Man, on the other hand, is believed to be capable of growing to become like God. The theological question is: where does engineering fit in the convergence of these two realms?

Papers for Parallels and Convergences: Mormon Thought and Engineering Vision should present scholarly discussions that explore scriptural background and LDS philosophy, set in the context of engineering and technology.
-----------------------
This looks like an interesting conference; I think its best potential lies in exploring connections between Mormonism and advances in technology. However, it could also be a menagerie of naturalistic fallacies--and don't get me started on Intelligent Design. Nevertheless, I'm glad to see these kinds of things happening. Maybe some time they can focus on Mormonism and stochastic processes.

The Argument from Resurrection

In arguments among Mormons regarding science and religion (or among Christians in general), it is not uncommon to see what I call "the argument from resurrection." It usually takes the following general form:

1. You claim that X is scientifically untenable.
2. However, the resurrection is also scientifically untenable.
3. We believe that the resurrection is (or will be) a reality.
4. Therefore, I am justified in believing X.

Something about how the argument from resurrection is often used bothers me, and I'll try to explain why. (Of course, my comments are based on an acceptance of #3 above.)

I think the fundamental problem lies in the difference between X and the resurrection--a false equivalence. Practically speaking, the resurrection is a future event or state, and it can be framed as a technological problem. Somehow, God can put us back together. It may seem impossible from our perspective, it may raise some tough questions, and perhaps our understanding or mental picture of the resurrection is not very accurate, but who is to say that such a technological achievement cannot be made. After all, God is God.

In contrast, the point of contention in #1 above usually involves a matter of history. The issue then is not what God could or could not do, but what the surviving evidence suggests. If the evidence contradicts X, then God's power, as exemplified by the resurrection, is really irrelevant. The question must turn to whether God would tamper with the evidence, which is not a scientific question.

Sometimes people slip into arguing over technical feasibility, which--with some exceptions--I think is a mistake [1]. So, for example, the issue with a global flood is not where all the water came from, or where it went, or whether Noah and his family could care for all of those animals. Although those are important questions, they are resolvable by appealing to miracles (i.e. God's superior technologies). The real issue is why geology, biogeography, and genetics do not give any support to such a flood.

Another example (if I recall correctly) is a certain book in which the author employed the argument from resurrection to support a literal interpretation of Joseph Smith's statement that

...the effect of the Holy Ghost upon a Gentile is to purge out the old blood and make him actually of the seed of Abraham.
If this is to be taken literally (and I don't think it need be), it is totally disconnected from modern biology. Again, the issue is not what God can do, but what we find if we look into the matter [2].

So when you see the argument from resurrection take a step back and determine what is at issue. Is it God's ability to do something, or is it the nature of the evidence? If it is the latter, then the argument from resurrection has probably been misapplied.


Notes:
1. The general exception to this is when someone makes a specific non-miraculous proposal. You can then follow-up on what the consequences of that proposal would be (i.e. what predictions it makes).

2. Remember that the mechanism of heredity was not known for another hundred years. The notion that blood was involved goes back to the ancient Greeks. Having said that, I doubt if a study has ever been done that compared the genetics of a Gentile pre- and post- reception of the Holy Ghost.

Magicians and Neuroscientists

I love a good magic show. Magicians and neuroscientists have teamed up to write a scientific paper. As described by the New York Times,

In a paper published [July 30] in the journal Nature Reviews Neuroscience, a team of brain scientists and prominent magicians described how magic tricks, both simple and spectacular, take advantage of glitches in how the brain constructs a model of the outside world from moment to moment, or what we think of as objective reality.
The paper, Attention and awareness in stage magic: turning tricks into research, is available to read for free. The paper is an outgrowth of a conference last year, of which some videos are also available for viewing. A few specific tricks are explained, but the discussion is mostly about general principles.

Incidentally, if you spend any time paying attention to the skeptics movement, you'll find the involvement of magicians. James Randi, one of the authors of the paper, is particularly prominent. Their expertise in deception, as part of their craft, gives them insight into evaluating paranormal claims. After all, they do make their living by appearing to do or know impossible things.

Scientific Advisors to the Prophet

Discover Magazine has an article, How to Teach Science to the Pope, that highlights a little known organization in the Vatican called the Pontifical Academy of Sciences.

Though it is virtually unknown among laypeople, the Pontifical Academy of Sciences is an independent and remarkably influential body within the Holy See. Over the years its membership roster has read like a who’s who of 20th-century scientists (including Max Planck, Niels Bohr, and Erwin Schrödinger, to name a few), and it currently boasts more than 80 international academicians, many of them Nobel laureates and not all of them Catholic—including the playfully irreligious physicist Stephen Hawking.

The academy serves an advisory role to Catholic leadership, and some scientific work is done under its auspices.
In 1992 John Paul II told the members that “the purpose of your academy is precisely to discern and to make known, in the present state of science and within its proper limits, what can be regarded as an acquired truth or at least as enjoying such a degree of probability that it would be imprudent and unreasonable to reject it.”

I wonder if our Church could use a similar organization--maybe an appendage to Correlation. Given how advancing science touches on Church policies and doctrines, it would be nice to know that the Brethren get good information to inform their decisions. You could make a case that BYU can serve that purpose; I wonder how often anybody in the basic sciences are contacted by Church headquarters for information or advice. (Steve P., got any stories?)

My guess is that when Church leaders feel a need, an ad hoc committee is formed involving GAs with the appropriate background and other prominent trusted professionals. Back in the 1970s James O. Mason--later the head of the CDC, and even later a Seventy--served as the Church Commissioner of Health and advised the First Presidency on certain health issues. I have no idea whether such a position still exists or not.

The Church Scientific Advisory Committee--I won't hold my breath, but I can dream.

Measles Up in the U.S.

The CDC released a report this week detailing an increase in measles cases this year. From January to July there have been 131 cases all around the U.S. One hundred twenty three of those are U.S. residents and 112 were unvaccinated--63 of them for religious or philosophical reasons.


The report reminds us of the importance of immunization.

In the United States, measles caused 450 reported deaths and 4,000 cases of encephalitis annually before measles vaccine became available in the mid-1960s (1). Through a successful measles vaccination program, the United States eliminated endemic measles transmission (1). Sustaining elimination requires maintaining high MMR vaccine coverage rates, particularly among preschool (>90% 1-dose coverage) and school-aged children (>95% 2-dose coverage) (7). High coverage levels provide herd immunity, decreasing everyone's risk for measles exposure and affording protection to persons who cannot be vaccinated. However, herd immunity does not provide 100% protection, especially in communities with large numbers of unvaccinated persons. For the foreseeable future, measles importations into the United States will continue to occur because measles is still common in Europe and other regions of the world. Within the United States, the current national MMR vaccine coverage rate is adequate to prevent the sustained spread of measles. However, importations of measles likely will continue to cause outbreaks in communities that have sizeable clusters of unvaccinated persons.

It's also important to remember that vaccination does not always confer immunity; a certain percentage of vaccinated people fail to mount a protective immune response. In fact, recently a co-worker told me that they had to get the MMR vaccine as an adult because even though they were vaccinated as a child, lab tests failed to find antibodies against measles.

The Science Behind the Anthrax Investigation

A Trained Eye Finally Solved the Anthrax Puzzle

The New York Times has a nice article on the scientific end of the anthrax investigation. After missing them using standard methods, scientists found that the spores used in the attacks contained several low-frequency mutants that were matched to Ivins' flask. Since Ivins was only one of a number of people with access to the flask, the science ends there. More interesting to me was that the FBI divided up the work to keep the assisting labs in the dark, just in case the culprit was working on the investigation.

As an aside, I've seen others complain about this before, but I will bring it up anyway. When journalists write about the sequencing of a genome, why are they so fond of using the word "decode"? According to my count, the second page of the story uses a form of the word seven times. Why can't they use the word that scientists use: sequence? The scientists were not decoding anything; they were determining the sequence that makes up the code. It's like saying that a doctor diagnosed a patient, when he really only took a history, performed a physical exam, and ordered lab tests.

Another Nail in Lamarck's Coffin

Last month I did a post on the role of E. coli in defeating the notion of Lamarckian evolution. I mentioned that there have been attempts to revive Lamarckism, specifically for bacteria. Essentially, there was experimental evidence that suggested that when bacteria are under stressful conditions, they can increase their mutation rate in order to increase their chance of hitting on a helpful mutation.

This week's Proceedings of the National Academies of Sciences has a paper dealing with this topic. Here is the abstract (but the full article is free to read):

Several bacterial systems show behavior interpreted as evidence for stress-induced mutagenesis (adaptive mutation), a postulated process by which nongrowing cells temporarily increase their general mutation rate. Theoretical considerations suggest that periodic stress-induced general mutagenesis would not be advantageous in the long term, due to the high cost of deleterious mutations. Alternative explanations have been tested for very few of the systems used as evidence for stress-induced mutation. In one prominent system, mutants resistant to rifampicin (RifR; rpoB; RNA polymerase) accumulate in cell populations that “age” on solid medium with little net growth. Mutant accumulation was initially attributed to stress-induced general mutagenesis in nongrowing cells. Evidence is presented that these RifR mutants accumulate because they grow faster than parent cells during the aging period. Direct tests revealed no increase in the frequency of other mutant types during the aging period.

Facts and Presidential Politics

I've avoided partisan politics on this blog and will continue to do so. However, with the presidential election approaching, debate over the candidates and their proposals is increasing--and as rhetoric increases, truth is often a casualty.

My favorite resource for separating fact from fiction is FactCheck.org. I have added their RSS feed to the sidebar, and I anticipate keeping it there until the election. At the very least, I hope to stay above the sleazy smear tactics, lies, and plain stupidity that seem to circulate at election time.

Happy voting.
