Replying to Science-of-the-Gaps Arguments



I had a commenter named Barry respond to my blog post "Why the Darwinist Version of Life's Origin is Anti-Science". First, he asked whether it is appropriate to couple the origin of life with neo-Darwinian evolution (it is), he then made the following statements:
You can't say "Well, we don't know how life emerged so God musta done it" simply because scientists don't know (yet). … That we don't know NOW how life began doesn't give anyone intellectual license to say that life has a supernatural cause due to a creative moment by a whimsical Omniscient Being. Relax. So we don't know right now what caused life to emerge. That's just the way it is. We'll understand some day. Maybe not in our lifetimes but it's likely to happen in the next fifty years or so.

In the meantime, God-of-the-gaps arguments aren't arguments from the point of evidence. They're arguments from the point of faith and belief. That's not a persuasive rhetorical tactic for the plain reason that reality is preferable to believing in things simply because you want these things to be true."
You will notice that Barry admits a couple of things. First, he holds that arguments that are not from the point of evidence are not strong. He refers to these as "intellectually feeble." He also admits that scientists don’t know how life began. In fact, they have absolutely no idea, no working models, nor even any controlled lab experiments that shows how one can get even a self-replicating RNA molecule from ribozyme components. I also brought this up in my response, pointing him to the enormous odds Dr. David Berlinski offered.

Barry’s response was telling. He replied:
Odds, shmods. It happened. Life DID emerge when it did and that's that. The only thing we don't understand is HOW life emerged—and there is zip evidence that it was due to some supernatural intervention. Evidence is tying a palm print on the rifle to Oswald. Evidence is collecting DNA from a crime scene and connecting it to a suspect. You? You got nuthin' to link to.
Can you see how this paragraph directly contradicts his previously stated view that arguments without evidence are intellectually feeble? Odds schmods?? It’s clear that Barry doesn’t care what the evidence (e.g. the mathematics) shows on the possibility of life emerging by chance. He simply wants it to be true. But that’s what the decried in the previous exchange! He’s not relying on a God-of-the-gaps argument, but a science-of-the-gaps one. He rejects the actual scientific data that that natural laws and chemistry alone could never assemble the first living organism simply because he doesn’t want to believe it to be true!

You’ll also notice that Barry claimed I had "nuthin' to link to." I did link to a couple of articles in fact, one being the Berlinski quote above. One of the main tasks of the scientific method is to either validate or falsify a hypothesis. You see, scientists understand that a negative result is still a result. We have data on what is required for life to exist, and it is showing more and more that spontaneous self-assembly is not a logical option. Asserting "we'll understand some day" is a statement of faith that directly contradicts the increasingly mounting evidence against the hypothesis.

To trust in science alone is not following the evidence wherever it leads. It is seeking to validate a preconception at any cost, something rational individuals should shun.

Can Governments Define Marriage? (video)



The issue of what marriage is who should be allowed to marry is making headlines around the world. With the homosexual lobby pushing for states to recognize same-sex marriage, it becomes more important than ever to understand just what marriage means and who has control over its definition.

In this video, Lenny explains that marriage stems not from any law or court decision, but from the same source as human equality: natural law. Thus marriage, like human equality, cannot be redefined.

The Odds Against a Natural Account of Life's Origin



One of the most fundamental questions human beings have asked "Where did we come from?" The Christian will respond that we are creations of God. Modern atheism, though, seeks to erase God from the picture by proposing that we came about as a result of a very lucky combination of material and the laws of science where short strands of polynucleotides—the stuff that makes up our DNA and RNA molecules—would stick together to form longer chains. The story goes that eventually, an RNA molecule would form that could self-replicate and life would begin.

Just how much luck was involved? Dr. David Berlinski discusses it here:
Was nature lucky? It depends on the payoff and the odds. The payoff is clear: an ancestral form of RNA capable of replication. Without that payoff, there is no life, and obviously, at some point, the payoff paid well. The question is the odds.

For the moment, no one knows precisely how to compute those odds, if only because within the laboratory, no one has conducted an experiment leading to a self-replicating ribozyme. But the minimum length or "sequence" that is needed for a contemporary ribozyme to undertake what the distinguished geochemist Gustaf Arrhenius calls "demonstrated ligase activity" is known. It is roughly 100 nucleotides.

Whereupon, just as one might expect, things blow up very quickly. As Arrhenius notes, there are 4100, or roughly 1060 nucleotide sequences that are 100 nucleotides in length. This is an unfathomably large number. It exceeds the number of atoms in the universe, as well as the age of the universe in seconds. If the odds in favor of self-replication are 1 in 1060, no betting man would take them, no matter how attractive the payoff, and neither presumably would nature.1
Following that description, Berlinski notes that Arrhenius seeks to escape his own dilemma by proposing that such long self-replicating sequences may not have been as rare in the primeval earth as they are today. He then answers:
Why should self-replicating RNA molecules have been common 3.6 billion years ago when they are impossible to discern under laboratory conditions today? No one, for that matter, has ever seen a ribozyme capable of any form of catalytic action that is not very specific in its sequence and thus unlike even closely related sequences. No one has ever seen a ribozyme able to undertake chemical action without a suite of enzymes in attendance. No one has ever seen anything like it.

The odds, then, are daunting; and when considered realistically, they are even worse than this already alarming account might suggest. The discovery of a single molecule with the power to initiate replication would hardly be sufficient to establish replication. What template would it replicate against? We need, in other words, at least two, causing the odds of their joint discovery to increase from 1 in 1060 to 1 in 10120. Those two sequences would have been needed in roughly the same place. And at the same time. And organized in such a way as to favor base pairing. And somehow held in place. And buffered against competing reactions. And productive enough so that their duplicates would not at once vanish in the soundless sea.

In contemplating the discovery by chance of two RNA sequences a mere forty nucleotides in length, Joyce and Orgel concluded that the requisite "library" would require 1048 possible sequences. Given the weight of RNA, they observed gloomily, the relevant sample space would exceed the mass of the Earth. And this is the same Leslie Orgel, it will be remembered, who observed that "it was almost certain that there once was an RNA world." 2
This section of Berlinski's article deals with just one step of a multi-step process that would fashion the first life. Other pieces include the advancement from self-replicating RNA to a fully working cell producing the appropriate amino acids and nucleic acids to function as well as assembling the right nucleic acids to construct the polynucleotides to begin with. And we haven't even factored in the problem of chirality.  However, looking at Berlinski's numbers alone, it seems clear that a reasonable person would not assume life came about by dumb luck.

Answering a Unique Objection to Natural Marriage Laws



Last month, I taught a class on how to engage the culture when discussing the issue of marriage, rights and homosexuality. One of the class attendees asked how she should respond to the argument she had heard from her professor in a university gender studies class. She said the professor, who identified herself as a lesbian, offered several arguments for allowing homosexual marriage, but there was one particular argument she hadn't heard before. She said, "One of the arguments was about hermaphrodites. Given that the intersexed were assigned a sex by their parents or doctor, they didn't get to choose. Because they are not strictly male or female, shouldn't they have the opportunity to marry whomever they want, regardless of the assigned sexed placed upon them growing up?"

I have to admit, I had never heard of such a tenuous argument either. However, this professor is not alone in thinking this way. The Intersex Society of North America (ISNA), a support group for those who are considered intersexed, offers a similar challenge on its web site:
People who are proponents of prohibitions against "same sex" marriage think it is easy to figure out who is "same sex" and who is "opposite sex." Not so…

Lots of people with intersex that we know are legally married. What will happen to them if we end up with simplistic notions of sex?

And lots of people with intersex we know can't get legally married, because some doctor decided for them which sex they would count as forever more. Why should a doctor get to decide who you can grow up to marry?1
While this situation seems pretty strange, it does require a response. First, we should comment on what constitutes an intersexed person. Most of the time, the label of intersexed is given to a person who is genetically male or female (XX or XY) but has ambiguous genitalia. These individuals comprise about .018% of the population, according to Leonard Sax. 2 This is an incredibly small portion of the population to base an argument for disregarding the concept of natural marriage that has been the foundation of human society for millennia. Even if we assume the ISNA's broader estimate, which counts those with chromosomal abnormalities, intersexed people comprise 1.7% of the total population.

Should Laws that Cannot Apply to All Apply At All?

The real objection offered by both the ISNA and the professor is that since the laws defining marriage would be considered unfair to those who are diagnosed as intersexed, they should not apply at all. Does that make sense? In my answer, I offered a counter-example. I pointed to a relatively common traffic law: if an emergency vehicle approaches with both a red light displayed and a siren sounding, drivers are required to pull to the curb. However, in my state, deaf people can legally obtain their driver's license, too. So, a deaf person could be ticketed for not obeying this law, even though it is physically impossible for them to hear the siren. Therefore, should such a law be repealed? Of course not! If the right curb rule was repealed, it would do much more harm than good; obstructing emergency vehicles and endangering drivers and emergency respondents.

A recent study estimates that between .9% to 2.2% of the population suffers from a significant hearing impairment. Does it make sense to change the traffic laws since they make no sense for this segment of society or would it make more sense to keep the law and review any citations individually? Legislation has always taken the latter approach. Similarly, it makes no sense to wipe out all the marriage laws with the advantages they offer society and the protections they provide children simply because they don't make sense to an even narrower portion of the population. The argument smacks to me of desperation.

"Lost Gospels" are to the Gospels as Sci-Fi is to Shakespeare



Yesterday, I began to discuss the so-called Lost Gospels, those second and third century writings claiming to be Gospel accounts by Apostles like Peter, Thomas, and Judas. As I noted, the Apostles names applied to these writing are clearly forged. The writings themselves are too late to come from those living at the same time Jesus ministered, unlike the four recognized Gospels of the New Testament. However, that doesn't stop some skeptics from trying to promote the idea that these documents are somehow on par with the canonical Gospels.

In his book Lost Christianities, Bart Ehrman makes the claim that there was some kind of competition between the four Gospels we know and these other writings. He states:
The Gospels that came to be included in the New Testament were all written anonymously; only at a later time were they called by the names of their reputed authors, Matthew, Mark, Luke, and John. But at about the time these names were being associated with the Gospels, other Gospel books were becoming available, sacred texts that were read and revered by different Christian groups throughout the world: a Gospel, for example, claiming to be written by Jesus' closest disciple, Simon Peter; another by his apostle Philip; a Gospel allegedly written by Jesus' female disciple, Mary Magdalene; another by his own twin brother, Didymus Judas Thomas.1
Ehrman then claims "Someone decided that four of these early Gospels, and no others, should be accepted as part of the canon," and then asks "How can we be sure they were right?"2

Obfuscating the Late Composition of the Gnostic Texts

As a New Testament scholar, Ehrman is being extremely disingenuous here. First, notice the phrasing of the sentence "about the time these names were being associated with the Gospels, other Gospel books were becoming available." It is written tom mislead readers that the Gnostic accounts are nearly contemporaneous with the Gospels. That isn't true. The Gospels were well known and circulated from the first century onward. As I've shown here and here, early church fathers named the authors of all four of the Gospels by 100 AD and no other candidates were ever seriously advanced. The Gnostic texts weren't even written until the second and third centuries, and that's when the church began making lists of what counts as Scripture and what doesn't. Thus, when Ehrman claims that "other Gospel books were becoming available," he means other Gospel books were being written. And when he claims this happened "about the same time these names were being associated with the Gospels" he means the Church put down on paper a list of Gospels bearing the names Matthew. Mark, Luke, and John.

But what of Ehrman's other claim that these texts were considered sacred, revered and worthy to be considered as part of the Christian Scripture? Internet skeptics make similar assertions all the time. However, these Gnostic texts, although labeled by their forgers as "Gospels" don't hold a candle to the real Gospels. In fact, all it takes is a quick read of them to show they are about as similar to the Gospels as a pulp science fiction novel is to one of Shakespeare's plays. Let's take a look at a few snippets to get a flavor.

Gospel of Peter

Ehrman points to the Gospel of Peter as a potential candidate for Scripture. Yet, in the Gospel of Peter, Pontius Pilate becomes free of all guilt because he washed his hands, thus flipping John's account on its head. It was the unwashed Jews and Herod that are supposed to take the blame for Jesus's death:
But of the Jews no man washed his hands, neither did Herod nor any one of his judges: and whereas they would not wash, Pilate rose up. And then Herod the king commanded that the Lord should be taken into their hands, saying unto them: All that I commanded you to do unto him, do ye.3

Such a re-envisioning of Herod's washing as a good thing is remarkable enough, but what's worse is how the account of the resurrection portrays Jesus coming out of the tomb on Sunday morning accompanied by two angels. All three of them have elongated necks and there a floating cross that answers God the Father! The passage reads:
They saw again three men come out of the sepulchre, and two of them sustaining the other and a cross following, after them. And of the two they saw that their heads reached unto heaven, but of him that was led by them that it overpassed the heavens. And they heard a voice out of the heavens saying: Hast thou (or Thou hast) preached unto them that sleep? And an answer was heard from the cross, saying: Yea.4

Certainly, the Gospel of Peter does not hold the same historical weight as the Gospel accounts.

Gospel of Thomas

The Gospel of Thomas was another account that Ehrman mentions. This text is interesting because it is probably the earliest of the Gnostic texts written sometime in the early or middle second century. But to call it a Gospel is to malign the term. First of all, it isn't a narrative of Jesus' ministry. It is only 114 verses long and is a collection of supposed sayings or teachings of Jesus. About a third of these are copied from the existing Gospel accounts. About a third are teachings not necessarily incompatible with Christian doctrine, but we don't know if Jesus said them. The last third, though, are completely Gnostic.

For example, take verse 22, which is comprised of double-speak :
 When you make the two into one, and when you make the inner like the outer and the outer like the inner, and the upper like the lower, and when you make male and female into a single one, so that the male will not be male nor the female be female, when you make eyes in place of an eye, a hand in place of a hand, a foot in place of a foot, an image in place of an image, then you will enter [the kingdom].5
Or verse 30, which is not only confusing but seems to reject monotheism:
Where there are three deities, they are divine. Where there are two or one, I am with that one.6
Finally, Thomas ends with a disturbing bit of Gnostic ideology where Jesus states only men can get into heaven and Mary Magdalene must be turned into a man to enter the Kingdom:
Simon Peter said to him, "Let Mary leave us, for women are not worthy of life." Jesus said, "I myself shall lead her in order to make her male, so that she too may become a living spirit resembling you males. For every woman who will make herself male will enter the kingdom of heaven.7
I could go on, but I think my point is made. The so-called Lost Gospels are nothing of the kind. They weren't lost, they were rejected. And they weren't Gospels, because they are devoid of the Good News of salvation. Of course, people can spiritualize anything; that's why a significant number of people in England and Wales identified themselves as holding to the Jedi faith.8 Holding that the Gnostic texts were serious candidates as Gospels falls into the same category as believing Obi-Wan Kenobi is a religious scholar. It makes me wonder in what way Dr. Ehrman watches Star Wars.
