Kids draw the Darwinest things

August 19th, 2012 | 1 Comment

My four-year-old was given this worksheet in Sunday School posing the first question in the Westminster Shorter Catechism for Children. The answer (“God”, duh!) was supposed to be written on the line within the cloud…a shape that my daughter somehow visualized as a sock monkey’s head.

Answer: My ape-like ancestors God

Despite appearances, my daughter was not actually trying to make a statement in favor of common descent; I haven’t even broached that topic with her yet.

But I can’t help dreading some sticky questions coming from her PCA Sunday School teachers if they inferred the same thing I did!

Occam’s razor can leave you bloody

June 28th, 2012 | 5 Comments

This will be a fairly short post — more of an excuse to rant than anything else. But I’m seriously tired of the common misuse of Occam’s razor.

Occam’s razor merely states that the simplest explanation is the best one. It’s roughly based on a law of logic that maintains that it is fallacious to posit more than what fully accounts for something as part of its explanation. This works extremely well for items of discernible composition: four quarters make a whole, and any more than that is not part of the whole, but something in addition to it.

What I object to is its use as an aesthetic masquerading as a principle of dispassionate logic. Too often people snip things away after unconsciously making assumptions about the composition of the thing being explained. Occam’s razor can easily cut out too much, and without analyzing those assumptions, it will never be noticed.

For instance, it’s often simply accepted that immediate causes and composition sufficiently explain. But that’s an aesthetic, not a precept of rational analysis: sometimes we would like to know more than the structural composition of a thing to understand it. Describing the raw materials is only enough when all you’re looking for is raw materials. But this is why Occam’s razor is useless for grander subjects: it frontloads the endpoint in question, styling the haircut (so to speak) after a preconceived, predetermined pattern. There are assumptions that go into what you think is necessary to explain things, and Occam’s razor is really handy for excising everything other than what you expected to find.

People wielding Occam’s razor to trim away everything but what they find personally interesting is not the same as saying that everything they trim is spurious, bogus, or otherwise worthless. When I walk into my back yard, see a shed that I didn’t know about, and ask my wife, “Where did this shed come from?” and she answers, “I got it from Big Lots,” I am fully enlightened only insofar that I wanted to know only the source of the raw materials. But it doesn’t answer, “Why is it here? Who assembled it? And where did the money used to buy it come from?”

Similarly, theologians and philosophers are always about answering more things than science answers. So when a materialistic scientists announces, “I’ve explained the natural causes of the universe! No need for the God hypothesis anymore!” we can safely say that they have taken Occam’s razor to everything but what most interested them.

And that’s ok–they can do a fine, parsimonious job of explaining that stuff. Just don’t let them try to tell you that there are no other questions worth asking.

James K. A. Smith on the missing Author in authorial intent hermeneutics

May 2nd, 2012 | 8 Comments

I realize this is a week old, which in the blogosophere can make something quite stale, but I had some thoughts on James K. A. Smith’s surprisingly negative review of Peter Enns’ recent The Evolution of Adam: What the Bible Does and Doesn’t Say about Human Origins.

Smith’s criticism focuses on Enns’ methodology, which is based on the reasonable belief that we can’t decide what God may have meant by a passage until we know the immediate, contextual meaning of that passage.

On the contrary, says Smith, “The church has always staked its reading of the Bible on the conviction that Scripture’s meaning exceeds what the original human authors could have intended.” Smith expects the Church to derive the most appropriate and relevant interpretations of Scripture by basing our interpretation in “worship”, whatever that means, “which will generate meanings…that could never have been intended by [the] human authors,” meanings that are “intended as meanings to be unfolded ‘in front of the text’ by the divine Author.”

The notion that there may be meaning in Scripture above and beyond the original meaning may be a conceivably defensible position (a position I once espoused on this site), but he doesn’t stop there: Smith insists that Enns is wrong to try to recover the meaning of the authors for the original audiences because of the danger of it hindering us from extracting a more appropriate, divinely intended meaning for us. So in reading Genesis, Enns should not expend so much effort in recovering the Ancient Near Eastern context, including relevant literary and archaeological backgrounding. That sort of research is well and good, Smith allows, but it doesn’t tell us what the Bible really means now, because it doesn’t take into account the meaning intended for us as contextualized within the Christian canon:

First of all, the Christian church is not a recipient of the book of Genesis as a discrete unit; we receive the book of Genesis within the Bible and that Bible is received as a whole—as a “canon” of Scripture.  Second, internal to the canon is the conviction that meanings God intends are not constrained by what human authors intended.

Although he puts his preferred hermeneutic in terms of “recontextualizing” Scripture, in essence Smith is wanting to theologize the text before situating it in history, because we are apparently not allowed to come to any conclusions by examining individual texts like Genesis and Romans that make it hard for this recontextualization (which in practice looks like front-loading) to occur.

Because Jamie Smith is no fundamentalist, or even a Chicago style inerrantist, he concedes, “Enns is exactly right to push back on ‘conservative’ or ‘literal’ readings of the Bible that anachronistically impose a ‘journalistic’ sense of ‘history’ on ancient texts.” But in this review specifically he seems uncomfortable with Enns’ claim that Paul and the author Genesis might not have intended the same meaning in their passages on Adam and Eve: “In fact, if it becomes a contest between ‘the authors of Genesis’ [note the scare quotes, presumably to flag Enns' avoidance of "Moses"] and Paul, Enns sides with ‘the original meaning’ of Genesis as the determinative meaning.” Not having read the book but broadly being aware of Enns’ perspective, I doubt that Enns would actually say either is determinative to the subjugation of the other; instead, it is Smith who wants to subjugate the intended message of both “Moses” and Paul to the meaning of the “divine Author”…whatever that might be. (I presume by Smith’s objection to letting Genesis carry its own meaning that he expects that God’s intended meaning happens to correspond more closely to Paul’s.)

But what of Smith’s “divine Author”? Should we put so much energy into finding the original meaning that we miss the message God intended for the Church to receive? My understanding is that Enns would affirm divine authorship in some capacity, although he rightly cautions us to avoid the “priority of the divine” that Smith here advocates.

To put it bluntly, I am no longer of the opinion that Scripture is layered with a special coating of “what God meant” sauce; neither do I believe that the Bible is composed of the flesh of human words attached to a divinely crafted backbone. Nor am I enamored with Peter Enns’ incarnational model of Scripture as I understand it, which is built off of the belief that divine and human authorship overlaps. In short, I have seen no compelling, non-circular reason to maintain the belief that God should in any meaningful sense be considered the author of the Bible. To believe in God’s providential intentions for the Church in the production and canonization of the Bible is one thing; I can affirm as much myself. To credit Him as the publisher might even work. I have sometimes drawn the analogy of God’s purposing of Scripture to that of King James commissioning the translation of the Bible. It occurs to me now that my view of Scripture as the response of humans to divine revelation and inspiration strikes me as fairly well analogous to a Festschrift. But God as author? Hardly. And the contention that He was the kind of author who overlaid the glaringly human text with some esoteric meaning recoverable independently of the meaning it had to the original audiences and available only to subsequent theologians reminds me quite a lot of the infamous “Bible Codes” from a couple years back. It sounds even more like Gnosticism.

But even if God did ordain a higher meaning upon the text, surely we can only hope to find it by first contextualizing and resituating each passage back in its original habitat and going from there. Otherwise the original meaning becomes completely incidental, despite the fact that something much closer to the original meaning than Smith’s canonical reading was the only one actually available to those who canonized it! They canonized the texts for what they were, not for some divine meaning that would override what they were after their canonization.

For these reasons, Jamie Smith’s canonical approach falls far short, and Enns’ approach – by no means uniquely his – of putting the effort into letting the original authors speak for themselves so that we can attempt to interact with each of them on a case-by-case basis handily continues to carry the day.

How the universe began ≠ why the universe began

May 1st, 2012 | 3 Comments

As I teased earlier, cosmologist Lawrence Krauss and astrophysicist Rodney Holder engaged in a conversation about cosmological origins on Unbelievable over the weekend. It was an entertaining though not altogether surprising debate, confirming my impression of Krauss’s book. I have not read it, but as I always say in these scenarios, reading the book is not a prerequisite for commenting on what the author says is the point and thrust of his own book. This is not a review of the book; it’s a review of some of Krauss’s ideas and his presentation of those ideas, which are presumably not that different from those argued in his book.

But I guess the point I’m trying to make is that the real, if you wish, miracle that people seem to think requires the existence of God is that you can create a universe full of stuff, full of stars, planets, humans, remarkable things out of nothing, literally where there were no stars, particle, space, etc. And that particular “miracle” is something that the laws of physics certainly has plausible explanations for.

If this summarized Lawrence Krauss’s book A Universe from Nothing: Why There Is Something Rather than Nothing as well as he claims it does, I doubt I would have any major problem with it. I like eliminating the god of the gaps as much as anyone. But Krauss and his New Atheist compadres have bigger ideas for his book than just that.

At one point in the interview he says, ”The key, fascinating thing to try to understand is how we got this amazing universe and how you don’t need a Creator; you don’t need someone to obviate the laws of physics to produce it.” In the book Krauss offers a few variations on how to answer the question of the universe’s origin. This would indeed problematize the cosmological argument, especially when the latter is being used as a proof rather than as a pointer; in science, the more plausible mundane explanations are available to contend with a counter-intuitive explanation, the less likely the counter-intuitive explanation (here, a divine miracle) appears. But Krauss’s interlocutor for this debate was less than convinced that his explanations were compelling enough to make natural theology an entirely superfluous supposition.

Holder, a former priest and a current astrophysicist, argues that in attempting to settle the philosopher’s quandary about the universe’s creation from nothing, Krauss does not properly begin with nothing. Indeed, in the interview, Krauss speaks of this or that conceived pre-Universe state as “approaching” the “philosophers’ nothing“. Holder is not convinced: ”He’s ontologized this nothing.” In one model under consideration, Holder points out that Krauss is not beginning with the absence of anything, but a quantum vaccuum. Krauss did not argue with this point.

Holder then noted that even under an alternative model discussed in the book beginning with an actual “absence of space,” Krauss speaks of this nothing as having properties, which would disqualify that lack of space from being the philosophers’ nothing: “…It has the property of being unstable; it has the property of being able to be acted upon by quantum fields and gravity and so on.”  Krauss objected that those things did not exist in that model: rather, there is a “metaverse” in which there is potential for those things to exist. Rejoined Holder, even the potential is not nothing. The existence of potential is still existence.

This prompted a pointed response from Krauss: “If the universe didn’t have the potential to exist, then how did God create it?” Krauss seemed similarly bothered by the “why? why? why?” question, to which he expected the answer, “turtles all the way down:” that is, if we persist on asking “why this created object?” until we get to an eternal object, we could still always ask “why that eternal object?” And like Dawkins, Krauss maintains that we could do this with the existence of God, as well.

Holder launched into an explanation of God as a necessary being, claiming that most scientists hold that the universe, on the other hand, is contingent. I consider that this difference in types of existence can conceivably be squared with apophatic theology of the Cappadocian variety, which despite on the surface maintaining that God Himself does not exist (and does exist) is really arguing that God has an existence of an altogether different kind than the way we can conceive of existence; He is the very basis for the kind of existence we are familiar with. Holder mentions Hawking’s discussion of what “breathes fire into equations.”

Another point in the book that Krauss wanted to point out is that the laws of physics creating and sustaining the universe could themselves be generated naturally. Holder didn’t repudiate the idea, but he apparently still wants to take it back one more step, asking why these particular laws exist: “So there can be the most wonderful theory, but why is this theory even instantiated?” They did not go far down this road in this discussion, but I wish they had had the time to!

One thing they did have the time to get into was the question of the value of philosophy.

Krauss stated his belief that physics has begun to answer the questions that used to be the domain of theology and philosophy. He argues that the philosophers’ distinction between something and nothing have been shown to be irrelevant distinctions under science’s microscope (note that in answer to the question of why there is something rather than nothing, Krauss in effect wants to deny the premise of the question). Although he occasionally equivocates on this, it certainly appears as though Krauss wants to bookend Sam Harris’s The End of Faith with The End of Philosophy.

Many philosophers are up at arms against Krauss for dismissing philosophy as increasingly irrelevant in his empiricist’s world of logical positivism, as he does in this interview (he admits that he “discounted” a recent scathing NY Times review because it was by a philosopher rather than a cosmologist). But this is not just some unfortunate parasite intruding on Krauss’s project. As fellow scientist (and atheist) Sean Carroll judiciously pointed out, this is at the core of Krauss’s project: as stated explicitly in this debate, Krauss believes that physics has demonstrated that the question of why is no longer more scientifically interesting than the question of why flowers differ in color. What Krauss is saying is that answering how, i.e. mechanical explanations, make irrelevant the question why, i.e. the question of meaning or purpose.

We can see the folly of approaching why as a how question in much smaller endeavors. If a man presented to his wife a beautiful oil painting he had created out of a spontaneous act of devotion to her, he would be wronged if she dismissed it as the ultimately meaningless result of oil smeared across canvas. In fact, the more brilliant and beautiful the painting, the more poignant its higher purpose would be to her.

More to the point, if my son were to ask me, “Why do I have to get a painful shot?” and I answered, “Because the needle triggers the pain receptors in your arm,” I have misheard his question as “what makes a shot painful?” rather than “why do I need to undergo this painful shot?” Similarly, answering “why does the universe exist?” as Krauss does is no different than if he had heard the question as “what makes the universe exist?” which of course an entirely different question than the one memorably posed by Leibnitz. Answering how manifestly does not render the question of why irrelevant. It is on this point that I agree with Gould’s NOMA principle: science seeks to answer how where philosophy and theology seek to answer why, and despite all of the efforts of Krauss and special creationists, both disciplines are ill-equipped to answer the other’s question.

This is why I’d be happy enough for Krauss’s book to completely decimate the cosmological argument. I don’t need it. I don’t need God to stand in that gap. But don’t try to tell me that knowing how something is accomplished in any way abolishes any attached purpose or meaning behind it, no matter how brilliantly or exhaustively you explain the how‘s.

The vacuity of materialism

April 24th, 2012 | 5 Comments

Most people are familiar with Carl Sagan’s famous declaration that “We are made of star stuff,” if only because of that song from a decade ago. It is often referenced to prove that even stereotypically stodgy, lab-coated scientists can have a sense of awe, an appreciation for intangible aesthetics like beauty, and even the occasional turtleneck sweater. The implication of our unity - solidarity sounds a little too punny – with the building blocks of our material universe on the basis of our common heritage from the Big Bang is a strangely resonating notion that science popularist Lawrence Krauss has recently capitalized on.

Krauss’s version of the motif, now a famous infographic, has gained a lot of recent attention for its having caused an Evangelical backlash against Miley Cyrus when she revealed on Twitter that she found it “Beautiful,” despite Krauss’s snarky materialistic send-up of one of the central ideas of Christianity.

There is indeed undeniable poetry in this. And one mark of a good poet is the ability to find beauty even in the sewage.

Conversely, a good satirist is able to expose a common perception of beauty as hardly more than a misidentification of sewage. To me, this comic from SMBC does a good job of approximating philosophical naturalists’ attempts to synthesize from pure matter the persistent human conviction that the universe has transcendent value, which has traditionally been explained by the belief that reality is comprised of more than merely conveniently-yet-coincidentally arranged atoms:

Why most Protestants need Adam and Eve to be historical

August 30th, 2011 | 16 Comments

…and why the Church in the East never did.

Listening to most Evangelical first-string leaders, you’d get the impression that apart from an historical Fall of Man that marred the souls of all the descendants of the ones who fell, you’d have no need for Jesus, and Christianity sails right out the window. So much more than inerrancy hangs on the question: original sin and total depravity hang on some sort of historical Fall, don’t they?

Perhaps they do (though not necessarily) — but the massive blind spot we have is that a rather large, ancient, and revered segment of the Christian Church rejected both of those teachings long before science came along and refuted the possibility of an historical first pair of human progenitors. And yet these believers still maintain that the work of Christ in atonement is absolutely necessary for every individual regardless.

Archbishop Lazar Puhalo explains:

The Schism between the West and the East is great indeed, so much so that Protestants rarely ever hear that perspective. These sorts of surprises are why I have begun to love glancing at Christian theology through the lens of the Orthodox.

The creolization of Christianity and the theory of evolution

August 10th, 2011 | 2 Comments

NPR has a rather good article up called “Evangelicals Question The Existence Of Adam And Eve” (sic — what the heck is up with the indiscriminate capitalization?). It vividly showcases how the tide is (finally) starting to turn in this culture war for/against evolutionary theory. Peppered with quotes from several key people, including Dennis Venema, Karl Giberson, Al Mohler, and Reasons to Believe’s Fazale Rana, the article points out that more and more self-described Evangelicals are coming to grips with the fact that the scientific evidence against a literal Adam and Eve is overwhelming.

Calvin College’s Dan Harlow underscores the importance of this discussion to the vitality of Evangelical Christianity when he says, “This stuff is unavoidable. Evangelicals have to either face up to it or they have to stick their head in the sand. And if they do that, they will lose whatever intellectual currency or respectability they have.” Respectability notwithstanding, conservative standard bearers like Al Mohler see nothing in Christianity worth holding onto sans a literal Adam and Eve. Despite Venema’s confident insistence that there’s nothing to be afraid of in accepting mainstream evolution (which decisively refutes two original progenitors), obviously there are some theological implications that remain in need of explanation. And although that end is not out of sight anymore, it’s still going to take a lot more work.

This reminded me of something I learned back in my linguistics program several years ago. (This isn’t a tangent: it’ll come back around!)

When two people groups speaking mutually unintelligible native languages come into contact and have need for communication, especially in a trade situation, they are likely to come up with some sort of compromise that will allow them to interact. Often they will form a sort of hybrid communication system taking elements from each of their languages. This communication system is called a “pidgin”: the vocabulary comes almost completely from the visitors who are seeking trade (historically, usually English or French) and the grammar (morphology, syntax) is taken predominantly from the native language. This system works well enough for trade, but pidgins are not classified by linguists as languages because they lack a number of grammatical features of natural human language. Because of its limitations, the pidgin is often spoken between the two language groups strictly in order to conduct business; the grammatical holes hinder much communication beyond such practical matters.

Yet in cases such as colonization in which the language of the traders makes an established presence, a pidgin may be spoken around young children who naturally adopt it as a native language rather than a limited communication system. In these cases, something very interesting happens: as part of the language acquisition process that comes so naturally to the young of our species, children fill in the pidgin’s holes. When children speak the pidgin to others, they unconsciously and effortlessly begin inserting new parts of speech, formulating verb tenses, bringing in missing vocabulary, and creating any other necessary language features that the pidgin lacked, so that the result is a robust, full-fledged language. This nativized pidgin is what is referred to as a “creole”.

Processes analogous to creolization recur outside language: quite commonly it’s in our children that thesis and antithesis are synthesized and for whom conflicts are likeliest to be resolved or otherwise fall away. Most of my peers in my generation grew up oblivious to and often incredulous of the traumatic struggle for racial equality that our parents and grandparents had to fight so hard for; I anticipate the same for my grandchildren in regard to the currently contentious issue of homosexuality.

I hope and expect this to happen also in the area of evolution and biblical literalism.

As a case in point, I had a conversation about woodenly literalistic interpretations of Scripture and evolution with my young daughter, a science nerd; at first, as a good Sunday School pupil (and my mother’s granddaughter), she was horrified to think about the possibility that what she’d heard wasn’t God’s truth (“But God doesn’t lie!” she once whispered desperately), but it was not too difficult to explain to her that the opinions of her creationist teachers hadn’t been taking all the important information into account. So in a relatively short conversation I was able to assuage her concerns and free her of some latent fears about her beloved science books so that she’ll be a part of the first generation of American Christians that tolerates some variation in the list of acceptable “vocabulary” for the origins question; in turn, theology/philosophy nerds (my son is already heading this direction) will nativize the “grammar” of how it all works and what it all means when taken together. Most importantly, they’ll now be able to look sympathetically at believers on both side of the question to an extent much more difficult for my generation and older.

I’m suggesting that we who have struggled in our exodus from conservative Christian theologies should not despair too quickly or fear too much for our children’s ability to retain and adapt Christian theology: this transition will not be nearly as difficult as it was for us who were more inculcated in our own native tongues before we made contact with those foreigners with their bizarre, barbarian languages. My hope is that, so long as we continue to stand by and tinker at the puzzle we’ve begun and teach our children to lay down their arms when dealing with those who disagree, we can trust that they will come in behind us and, relatively effortlessly, fill in the holes.
