Not losing sight of the truth in the fog of war.

 A War of Words? How to Tell Who Won the Tour-Farina Debate


A few years ago, just as I was finishing writing my PhD thesis, I received an email from an Internet questioner with the subject “War of Words.” This person expressed concerns that there is so much back and forth between experts in the debate over the origin and evolution of life and intelligent design, that it can sometimes be difficult for a non-expert to determine who is right. I can sympathize with this: Even though I have multiple science degrees, took many undergraduate and graduate courses in evolution, and have closely followed the science for years, it’s still a challenge to keep up with everything. What’s a non-expert to do?

Last Friday we witnessed a debate on the origin of life (OOL) between two widely followed voices on the topic: Rice University chemistry Professor James Tour, and YouTube science educator Dave Farina, aka “Professor Dave.” This debate, which took place on the Rice University campus, was at times turbulent, but it provides an apt example of how to answer my “War of Words” Internet questioner.

“No Viable Model”

The topic of the debate was: “Are We Clueless About the Origin of Life?” Discovery Institute did not organize this debate and I was not a big fan of this framing because it would be much harder to prove a high standard, that OOL researchers are “clueless,” than it would be to prove some lesser — but still entirely reasonable — claim like “There is no viable model for the origin of life.” Nonetheless, Tour faithfully stuck to the debate topic, and he made a strong scientific case against the natural chemical origin of life. 

Dave Farina represented the standard view that unguided natural chemical processes could have produced the first life on earth. Unfortunately, however, Farina decided to focus on a very different debate topic. His topic was essentially — no exaggeration — Is James Tour a liar and a fraud? — and that is precisely what he asserted over and over again throughout the night. Farina’s venom and personal attacks and insults against Tour knew almost no boundaries. It was a spectacle, and I was shocked that the moderator allowed it to proceed. But Farina’s focus on personal attacks and his repeated refusals to answer Tour’s reasonable scientific challenges made it clear to many viewers that Tour had the better argument. 

If you don’t believe me, consider some comments on the YouTube chat posted by viewers who are apparently self-described as atheists, agnostics, and/or former supporters of Farina:

“Am I the only non-religious person that finds Tour much more convincing than Dave? This debate made me further convinced. The problem with Dave is that strangely, as an educator, he in no way tried to educate James Tour, but only attack him and slander him, he has zero class, and from a psychology standpoint, seems like he did nothing but dodge and deflect, which would suggest he doesn’t have a deep understanding of the subject, but merely a surface level one, a true scientist wants people to understand the truth, and would carefully address Tours questions concisely and on a deeper level.”
“I’m an atheist, however, Farina’s smug and snide attacks on Tour throughout this debate, disgusted me. I may disagree with Tour’s mission, however, no one can ignore his considerable contribution to science.”
“I’m agnostic, but hearing Dr. Farina’s statements, grounded on insulting and sarcasm sincerely show more how clueless he or his community are…usually when you use sarcasm it is because you have [little] to say. I say this as an academic myself (other field though) when I see colleagues use sarcasm is because they don’t know how to ground their statements.”

“I’m [an] atheist and this was embarrassing to watch. Dave claiming that James doesn’t know how to read papers, while…citing barely anything beyond the titles of a bunch of papers. I think that disrespecting the audience and claiming to know what they do and don’t know was the worst move of the entire debate. It shows that he’s arguing emotionally.”
“I’ve been floating around this conflict, viewing from the outside. Dave’s videos helped me in middle-high school. Dave poisoned the well, then used insults and rhetoric as the substance of his ‘argument’. This was disappointing, I was hoping he would bring something of value. Dr. Tour won this one.”

You Don’t Need a PhD

So even though my “War of Words” questioner worried that you need to be an expert to sort through these issues, I’m going argue here that you don’t need a PhD in science and unlimited time to read the literature to quickly see who has the better argument.

You may not be an expert in chemistry like James Tour with a lifelong career trying to synthesize molecules in the laboratory. You may not have published hundreds of peer-reviewed chemistry papers like Tour. You may not even have taken any college-level science courses. But you can watch the debate and learn a lot about who has the upper hand on the OOL question. If you want to know who has the better argument, examining the rhetorical styles of different “sides” of a debate can speak volumes.

Over three subsequent posts, I’m going to elaborate on three reasons that we can see that Tour won, based upon a rhetorical analysis of the debate (plus a little science):

Tour focused on science, Farina focused on character assassination.
Tour posed reasonable scientific challenges which Farina refused to answer
Farina relied heavily upon playground tactics, appeals to authority, and citation bluffing.
We’ll tackle the first reason in the next post. But first a viewer’s warning.

Not for the Faint of Heart

As the debate wore on, at times both participants got quite intense; if you don’t like raised voices, don’t watch this debate. Frankly, as Farina spewed more and more venom against Tour, at times he (Tour) became animated, and even took a few shots at Farina’s chemistry knowledge. Tour’s words about Farina weren’t remotely comparable in intensity or number to Farina’s personal attacks on Tour. In my next post you will read a sampling of just some of those personal attacks. So if you are bothered by Tour’s irritation, ask yourself: Could you withstand such hatred and not get a little hot under the collar? James Tour is a great man…but like the rest of us, he is after all just a man. 

Regardless, it’s undeniable that this debate got a bit ugly and it reminded me why sometimes I don’t like debates. I do wonder if it was wise to give a platform to a person like Farina who was so thoroughly and unabashedly dedicated to making the night about assassinating James Tour’s character rather than investigating the science. Perhaps the moderator was given instructions to keep the debate going no matter how much nastiness and personal venom Farina threw at Tour. I really don’t know. But this is the kind of thing, unfortunately, that needlessly turns some people away from otherwise serious scientific conversations and dialogues over important questions about origins and science / faith issues. 

One Other Thing Is Clear

Farina is a skilled at quickly throwing out lots of arguments of varying quality and then using passive-aggressive maneuvers aimed at provocation. If you are the type of person who is susceptible to theatrics, intimidation, mockery, and character assassination, you might think Farina won. But once you climb out of Farina’s world of venom, invectives, mockery, and rapid-fire citation bluffs, you realize there isn’t much there. On substance, James Tour won the debate handily. Despite a few lapses here and there as the night wore on, overall he focused strongly on the science and made loads of good arguments that Farina did not address. That’s simply a fact.

But even if you didn’t know much about the science, you can easily tell who came armed with facts, knowledge, and a passion for seeking out the truth, and who came with a simple goal to destroy his opponent, at all costs. I’ll be back tomorrow.

 “Well, Everyone Has to Have a Birthday” — How Professor Dave Botches Probability


This past Friday (May 19, 2023), Rice University professor James Tour “debated” (I use that word advisedly) YouTube personality and influencer David Farina (known as “Professor Dave”). The question up for discussion was “Are we clueless about the origin of life?” Tour took the position that the origin of life is a completely unsolved problem. Farina took the position that research in the origin of life is making good progress. Tour focused on the chemistry. Farina focused on discrediting Tour, calling him a liar and even a pathological liar over and over again. He also called Tour and his supporters clueless. (Does it take a pathological liar to falsely call someone a pathological liar? How clueless does one have to be to falsely call someone clueless?)

Farina’s antics got so wearisome that I could not watch the entirety of the debate. Indeed, I would not call it a debate. On the one hand, there was Tour trying to engage in substantive questions about prebiotic chemistry. And there was Farina, attacking him personally, both as someone completely unqualified to address the origin of life and as someone so biased by his religious beliefs as not to be trustworthy on scientific issues (Tour is unreserved in affirming his Christian belief). 

Citing Article Titles

The only science, such as it can be called, that I saw from Farina during the exchange was citing titles of origin-of-life articles that he claimed redressed the problems Tour was raising. But these seemed to be just arguments by irrelevant reference that fittingly complemented his arguments ad hominem. Farina gave no evidence that he understood the articles he was citing. It was as though origin-of-life researchers hostile to Tour had simply provided Farina with ammunition for the exchange.

My opinions are what they are, so form your own conclusions. Here is the exchange (“debate”). If you are able to watch the whole of it, give yourself brownie points for endurance. 

<iframe width="460" height="259" src="https://www.youtube.com/embed/pxEWXGSIpAI" title="Dr. James Tour vs Dave Farina | Are we clueless about the origin of life? #abiogenesis" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share" allowfullscreen></iframe>


Farina’s performance in the exchange didn’t surprise me. It was consistent with what you see on his YouTube channel when he is promoting atheism, though I would say that in this case it was especially extreme. Was his scalding behavior intended to score points with his atheist supporters? Was it to boost his number of YouTube followers? I wonder how his performance would be interpreted by the unwashed middle, i.e., those who have no particular stake in the origin-of-life controversy. He was arrogant and cocky. I have to think that this didn’t help him with those outside his circle. But who’s to say in this age of social media where sensibilities get so warped. 

To Command an Audience

Tour admitted at the start of the exchange that this was his first debate. I’ve seen him give talks on not just the origin of life but also his own research, and he is able to command an audience, not only with his knowledge but also with his stature. I myself have debated atheists, such as Michael Shermer and Michael Ruse, but those debates were always respectful. To have your interlocutor, like Farina, hurling insult after insult at you has to be disconcerting. And it shifts the focus from the substance of what should be discussed to the credibility of the participants. Should Tour have attacked Farina for his limited chemistry background, which includes only a bachelor’s in chemistry and a master’s not in chemistry per se but in chemistry and science education? Tour is a Nobel laureate caliber chemist. 

Should Tour really have had to endure the constant jibes of Farina? Farina was at Rice at Tour’s invitation, so Tour’s natural inclination would have been to play the gracious host. He even started the exchange with a gift to Farina. But still, Farina should have been reined in. I suspect Tour was unprepared for the vitriol he encountered. I lay some of the responsibility for Farina’s continued shameless display on the moderator. Early on, the moderator should have told Farina that the audience by now had gotten the point that Farina thought Tour was a “pathological liar,” and that he should confine himself to the question that was the topic of the debate. The moderator should also have put an end to the constant interruptions of Tour by Farina.

Information and Probability

Two years ago I was interviewed by Tour for his YouTube channel about my work on information and probability. What prompted Tour to interview me was some probability arguments by Farina against him. Here’s my interview with Tour:

<iframe width="460" height="259" src="https://www.youtube.com/embed/YAVHYhiVbyY" title="The Science &amp; Faith Podcast - James Tour &amp; William Dembski: Information Theory" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share" allowfullscreen></iframe>

At the 31-minute mark, Farina makes a probability argument dismissive of small probabilities in design inferences. When I reject Farina’s discussions of origin-of-life chemistry, it’s as an informed layperson and yet as a non-expert. But when I see how Farina botches his discussion of probability, a field in which I am expert, it suggests to me that either he is confused or he is so committed to his atheist agenda that he will bend any argument to serve that agenda. Farina seems obsessed with Tour, having posted nine YouTube videos against Tour.

At the 31-minute mark, Farina offers the following analogy to argue against inferring design on the basis of small probabilities:

Let’s say 10 people are having a get-together, and they are curious as to what everyone’s birthday is. They go down the line. One person says June 13th, another says November 21st, and so forth. Each of them have a 1 in 365 chance of having that particular birthday. So, what is the probability that those 10 people in that room would have those 10 birthdays? Well, it’s 1 in 365 to the 10th power, or 1 in 4.2 times 10 to the 25, which is 42 trillion trillion. The odds are unthinkable, and yet there they are sitting in that room. So how can this be? Well, everyone has to have a birthday.

But Farina here misses the key second component of design inferences: they do not just require improbability but also specification (namely, conformity to an independently given pattern). Farina’s pattern of birthdays is completely unspecified. Imagine, instead, that each of these ten people had reported that their birthday is January 1. Such a coincidence would be independently given in virtue of its short description, such as “everyone has the same birthday” or “everyone was born New Year’s Day.” It would therefore constitute a specification. By combining small probability and specification, this coincidence would therefore have called for an explanation other than chance. It would not, in that case, be enough to say, as Farina did, “Well, everyone has to have a birthday.”

Farina exudes confidence in the absence of deep knowledge and understanding. In fact, his expertise is quite limited. But he’s a quick study at getting down “industry” talking points. And he can marshal titles, abstracts, and authors associated with research articles to suggest that whatever he wants to assert has in fact been established or is on the verge of being established. But as a YouTube influencer, his main incentive is to play to the gallery. And as an apologist for atheism, his interest is not in advancing science but in using a warped materialistic conception of science as a club to beat religion and religious believers. 

I’ll be interested to see what the aftermath of this exchange will be. As of yesterday it had 11,000+ comments on its YouTube video. So it hit a nerve.

 Where’s the Chemistry? On the Origin of Life, James Tour Exposes Professor Dave as “Clueless”


Last week, renowned Rice University chemistry professor James Tour debated popular YouTuber Dave Farina, aka “Professor Dave,” on the origin of life. The debate took place on the Rice campus in Houston, Texas, in Tour’s own lecture hall, and was Streamed live over the Internet. Unlike Dr. Tour, Farina isn’t a real professor. I suppose in today’s manner of speaking, we could say that he identifies as one, while lacking a PhD, a faculty position, or as it seems now, anything like the needed chemistry expertise to explain how life arose. 

One Thing Seems Clear

The topic of the debate was: “Are We Clueless About the Origin of Life?” After watching it, one thing seems clear: Professor Dave, like the origin-of-life field itself, is certainly “clueless” about any reasonable level of chemical detail about how the origin of life might have occurred.

The mic drop moments of the evening came after the opening statements when each debater was given the opportunity to ask his opponent questions. Tour focused on the science. The challenge he posed to Farina was simple: If Farina really thinks the origin of life has been explained, come to the blackboard and show the audience the chemistry that can produce, under realistic prebiotic conditions, five key elements of biology. Those are polypeptides, polynucleotides, polysaccharides, specified information, and a functional cell. 

In each case, Farina declined. 

Tour listed those five key elements of biology on the blackboard. At the end of each, after Farina had refused to come to the blackboard to explain the chemistry to the audience, Tour wrote “Clueless” next to the item. In another context this might have seemed harsh, but given that the agreed-upon question of the night was whether origin-of-life researchers are “clueless” about how life arose, it seemed entirely fair

A Scientist Comments

While Tour focused on the chemistry, Dave Farina spent most of the evening directing personal attacks against Dr. Tour, calling him a “liar” over and over again as well as many other invectives. We’ll discuss this distasteful aspect of the debate further in a subsequent post. A friend of mine who is a scientist watched the event and had this to say: 

I went into the debate knowing very little about Dave. I had no feel for his level of competence in chemistry or OOL issues. (I know Jim Tour, so I know he’s an expert chemist.) I was open to Dave being a self-taught expert on the issues, willing to push back on Jim’s dismissals with clear evidence.

In his opening volley, Dave made it clear that he wasn’t there to discuss chemistry, he was there to attack Jim. This is less than persuasive, since even if Jim was a donkey, there are prebiotic chemistry questions that need to be answered. It doesn’t matter who’s asking them. (It didn’t help that they were at Jim’s home campus, and Dave is calling him a fraud to his colleagues who know he’s not a fraud from direct experience.)

The turning point in the debate in Jim’s favor was when he wrote, in chalk, the precursor substances and the derived substance schemata. He then called Dave’s bluff: if we are not clueless on how this was made chemically, write the equations. “But mountains of peer-reviewed literature explain it…” Dave suggested. OK, then open those papers, find the equations, and write them here. Dave couldn’t.

It became clear to an outsider like myself that (1) the pathways and equations weren’t actually known, and (2) if they were known and actually in the papers, Dave couldn’t understand them. Or else he would have simply written down the relevant reaction equations.

A good portion of the audience seemed to realize this, too, and began to turn against Dave, prompting him at points to lash out at them. (Pro tip: In a debate, if you ever get to the point where you’re attacking your own audience, you’ve lost.) But I’m biased, so I checked the YouTube comments to see if my perceptions were widespread. I saw more than a few comments from atheists and those on Dave’s side saying he embarrassed them in the debate. Dave literally had nothing but personal attacks and pointing to words in paper titles and abstracts. Jim had actual chemistry. The comments section showed that even Dave’s own crowd saw this as a loss.

A Lost Opportunity

Indeed, Farina made many assertions about various scientific papers — and we’ll be discussing those soon. But Tour gave Farina a clear opportunity: If the paper explains how key aspects of life arose, then write on the board the chemical reaction equations that show how it happened. Farina would not even take the chalk. He couldn’t do it. If he could, he certainly would have done so.

At end of the debate, Farina finally took the chalk and wrote something on the blackboard. It was two words: “NOT CLUELESS.” It was intended as cheekiness, but it only served to highlight the fact that Farina was unable to explain details of the chemistry behind the origin of life. More importantly, it didn’t answer Tour’s request for a scientific explanation. Farina could not answer a single challenge from Tour. 

Professor Dave’s inability to provide the chemistry to back up his claims calls to mind the famous Wendy’s ad from the 1980s, where an elderly woman keeps asking: “Where’s the beef?” One might likewise ask Dave Farina: Where’s the chemistry? For that, don’t look to Professor Dave.

It was a turbulent evening, but that was the main takeaway from the debate. We’ll offer more analysis in subsequent posts.

Dave Farina: team atheism's LVP?

 Atheists Review Professor Dave’s Debate Performance


As someone who purports to educate others about science, Dave Farina has strengths and weaknesses. With 2.48 million subscribers on YouTube, Mr. Farina of “Professor Dave Explains” has a style that many find gratifying. As Professor James Tour said in their debate on the origin of life, Professor Dave has “tremendous reading skills” — he can read from a script, on YouTube or in a debate, with fluency and confidence. What Farina apparently can’t do, as Tour also noted, is “speak chemistry” on his own, when challenged and not using a script as a crutch. It also seems he can’t write chemical formulas, relevant to abiogenesis, on a blackboard with ease. Weak professional training may have something to do with his reliance on mindless sneering and insults. That’s my take.
          
“Do Better Next Time, Dave”

Of those who enjoy Farina’s style of juvenile personal abuse, I guess that most are atheists — by which I mean no disrespect to thoughtful atheists or agnostics! So I was curious what atheists made of his performance against Dr. Tour. In the comments section below the debate on YouTube, we find:

Keith Williams: “I’m an atheist, however, Farina’s smug and snide attacks on Tour throughout this debate, disgusted me. I may disagree with Tour’s mission, however, no one can ignore his considerable contribution to science.”

Artha Peterson: “I wonder why an actual abiogenesist won’t debate him [meaning, Tour]? That’s a serious question. Someone who actually can do the chemistry, unlike Dave. That would be the way to silence Tour on that topic forever. And yes, I am an atheist and yes I believe in abiogenesis.”

Lars Cade: “I’m an atheist and am already quite aware of the many ways in which Tour ignores or misrepresents data in his futile attacks on abiogenesis research, but he did far better in this debate than Farina. He laid out his definitions and stuck to the data and the topic. Because this is a very technical field, that’s all he needed to ‘win’ the debate. Do better next time, Dave.”

CaseAgainstFaith1: “Hi. I’m an atheist and I attended in person. Now I have not the slightest clue about the relevance of many things brought up during the debate. Like I have no clue about the 2,5 vs 3,5. I can say that Dave’s constantly calling Dr. Tour a liar and also insulting the audience was not helpful. Dr. Tour’s screaming wasn’t helpful either. But if I had to pick a winner I am afraid I would give it to Dr. Tour.”

thatwmckid: “I’m an atheist and I actually agree with James Tour.”
