Biology as Ideology: The Doctrine of DNABiology as Ideology: The Doctrine of DNA by Richard C. Lewontin

Lewontin is a leftist and he couldn’t be more obvious about it. When he unconvincingly accuses all science of being ideological, it seems like he’s preparing the ground for and justifying the strong ideology behind his own writing. He refuses the extreme idea that genes are the source of all causation in the human sphere, only to replace them with bourgeoisie and capitalism! Yes, he takes particular delight in linking everything from reductionism as a scientific tool to the information-theoretical paradigm in biology back to “the bourgeois revolutions of the eighteenth century”. It’s funny how reductionistic leftists can become when trying to refute reductionism.

It’s one thing to dream of a more egalitarian, more democratic and more fair society; it’s another to filter facts according to that dream. I find this confusion especially troubling for a scientist: everything he writes suggests that if ever science shows beyond dispute that intelligence – or some other “good” human quality – is differentially inherited, he will reject that conclusion just because it’s not in line with his precious ideals of equality and fairness. (He actually has a go at it in the book, and maybe this isn’t much of a problem for him since he admits that scientists are inevitably ideological creatures.)

Speaking of fairness, I actually loved the book (1) because it is nicely designed and (2) because Lewontin certainly has a rare gift of balancing our thinking against the sometimes lazy Dawkins-Dennett line of thought by pointing out neglected perspectives and offering a lot of food for thought. The problem is that – just like his ally Gould – often he’s pushing it too far, to the point that the poor arguments injected at those specific points compromise his otherwise amazing authorship.

Another problem worth noting is that in some of the corrections he proposes for the Dawkinsian reductionism – again, just like Gould – he is actually overlapping with what Dawkins says, only with a different vocabulary: the contructionism (“the environment of organisms is coded in their DNA” – p.112) that he defends against adaptationism is the same as Dawkins’s concept of extended phenotype (1982), and the below passage with which he closes the book (1991) is one step shy of memetics (1976).

(…) the genes, in making possible the development of human consciousness, have surrendered their power both to determine the individual and its environment. They have been replaced by an entirely new level of causation, that of social interaction with its own laws and its own nature that can be understood and explored only through that unique form of experience, social action.

In this respect, he reminds me of Dennett’s metaphor for Gould in Darwin’s Dangerous Idea: the boy who cried wolf.

Dawkins vs Gould: Survival of the FittestDawkins vs Gould: Survival of the Fittest by Kim Sterelny

I had low expectations for this book because of its (typographically) cheesy cover design and clumsy typesetting. In the end it made me want to read his other books.

The author uses the debate between Dawkins and Gould to walk through many important topics in evolutionary biology, mentioning lots of other scientists and philosophers on the way, and successfully switching between detailed examples and the big picture. He definitely knows what he’s talking about, and his writing is so clear and concise that it somehow resonates with the in-your-face 12-point Baskerville it’s set with. Even so, I would recommend it to those who have read Dawkins/Gould and are somewhat familiar with their ideas. The book ends with an amazing Suggested Reading section where Sterelny makes useful comments on every book he suggests.

In any case, Kim, if you’re reading this: change your publisher. Your book deserves better design.

And this is something I did (based on the original) reflecting where I stand on the debate:

Here it is, finally, Dan Dennett’s Istanbul talk titled “Darwin’s Strange Inversion of Reasoning” from last year. Enjoy.

Filmed, edited and subtitled by me. I thank Eser Aygün, Amaç Herdağdelen, Murat Özsaltık and Bilge Kobaş for their help.

Reminder: This was part of a series of events titled “Darwin and Beyond” organized by Sabancı University to celebrate the Darwin bicentennial, April 10, 2009, Sakıp Sabancı Museum, Istanbul. See also previous related posts.

It’s been some time since I finished reading Darwinizing Culture: the Status of Memetics as a Science edited by Robert Aunger and I’ve been thinking on a few major points that bother me, not in the specific claims of the contributors but in the way the issue of the validity of memetics is often discussed. So even if this may look like a book review, it is in fact the expression of my general discontent about the “meme talk” and my suggestions on how it might be turned into a more healthy discussion.

First of all, I have trouble understanding why nearly all the arguments in the book revolve around human social behaviour and how hard it is for memetics to account for it. My opinion is that this perspective misses the real power of memetics.

Social behaviour is also present in animal species (many of which do not exhibit signs of proto-culture) and yes, it can be explained without much need for memetic theories. So why, when it comes to human social behaviour and psychology, leave this all behind and expect memetics to account for everything on its own? Humans are animals too, and possible memetic explanations will be additions to the basic ethological/psychological explanations. It seems to me that the reactions of psychologists and anthropologists against memetics are based on a misunderstanding that memetics is here to sweep their theories on human nature away and start from scratch.

The point I want to stress here is this: I believe that the strength of the meme theory will unfold when it’s applied to account for the relatively new layer of things which have covered the surface of the Earth within the last 10.000 years: tools, signs, books, roads, cars, ships, airplanes, buildings, cities, factories, toys, songs, computers, cable networks, satellites… Everything “designed” by humans. This is where we differ from animals on a very observable level and this, I submit, is the domain where memetics as a research program can produce its first fruits without too much hassle with other disciplines – thus, the domain where arguments about the validity of memetics should move towards.

Of course, the issue of what Aunger calls Mental Darwinism becomes important here: is human creativity the product of the evolutionary algorithm running in human brains as Susan Blackmore argues, or does this view depicting humans as mere vectors arise from an “insufficient understanding of the autonomy of (memetic) agents” (my italics) as Rosaria Conte asserts in the book? I propose that two things should encourage us to operate under the assumption that Blackmore is right, and embark on the project of analyzing cultural designs within the memetic framework: (1) the stunning power of evolution in creating design, demonstrated in biology and in the digital evolutionary algorithms used today in many areas for creative design or optimization, and (2) the delusional nature of our introspections and intuitions about our precious conscious autonomous agency, as revealed by neuroscience and cognitive sciences (see Dan Dennett’s Consciousness Explained). The second point is echoed, strangely enough, in Conte’s chapter:

But a decision-based process is not necessarily explicit and reflected on: mental filters do not necessarily operate consciously, so agents may not be able to report on them.

Substitute “mental filters” with “mental memetic selection pressures”, and you get a sentence by Blackmore! This simply is the essence of the memetic account of human creativity.

But the project of explaining human design with memetics needs one big adjustment in the way people conceive of memes. This is the second point that disturbs me in the discussions in general: the misguided use of the term meme.

The critics of memetics often talk of things like “the God meme”, “the chair meme” or even “the general relativity meme” in their refutations. These concepts may be straw men created by the early proponents of memetics (like Richard Dawkins in The Selfish Gene), and no wonder they are easily burned down by critics speaking in sarcastic tones. (see Adam Kuper’s section titled ‘The Ecology of Ideas’ for a perfect example.) This simplistic language, still adopted by some memeticists today, is turned against the memetic theory to condemn it as an oversimplification too funny to be true. But although it is true that memeticists haven’t agreed yet upon a single definition for the term meme, it seems obvious to me that, whatever it will be, it won’t be that simple a definition to allow us to talk about “the chair meme”, let alone “the general relativity meme”, for the same reasons why we don’t talk about “the bird gene”, or even “the wing gene”, or even “the feather gene”, and so on – to the point where we realize that there isn’t a one-to-one mapping between the features as we distinguish at the phenotype level and the genes. The genes constitute a recipe, not a blueprint. What makes us think that memes are much more simpler structures?

In fact, the original operational definition by Dawkins of the meme as the unit of cultural selection is sufficient to reveal the absurdity of the “the x meme” talk: even a simple chair design is way too big and complex to be a unit of selection. Just like the biological organisms, cultural objects (artefacts, theories, institutions, etc.) clearly are products of complex interactions between tiny bits of information acting as units of selection. In this perspective, the general relativity theory is a memetic construct, resulting from the interactions of maybe thousands of memes that we may not readily map one-to-one onto the properties that we perceive and talk about on a semantic level.

As Dennett reminds us on various occasions and topics, we must be prepared to, if not expect to, discover that accurate scientific theories are often counter-intuitive. Our intuitions are not a good basis for building or refuting claims about the nature of our minds and the memes, as they lead us to overrate our conscious teleological control over our creativity or to engage in a semantic mapping between whole designs, ideas or theories and single memes.

So it is my belief that memetics should – in the beginning, at least – shift its focus from human social behaviour towards human creativity and objects of culture, and do that with a more refined definition of meme to do justice to the complexity of the phenomena to be explained as well as to the memetic theory itself. Imagine how far population genetics could have gone if geneticists were talking about “the dog gene” and “the human gene”; that’s how far memetics can go if we don’t quit talking of “the chair meme”.

I’ve finally watched Ben Stein’s Expelled: No Intelligence Allowed, an authored documentary on the Intelligent Design (ID) movement. My review of it will deal with the twisted structure of its argumentation and not with the ID ideas themselves because there are experts on the subject who successfully refute the few legitimate ID arguments.

Expelled.No.Intelligence.Allowed

The main argument of Expelled is that the ID proponents are unjustly expelled from the academia to hide the big crisis in evolutionary biology (huh?), and the film starts with the metaphor (which it continues to make large use of) of the Berlin wall and oppressive regimes for the ban of ID from science. I was determined to put my years of reading of evolutionary biology aside and to try my best to watch it as objectively as I could as a person outside the particular scientific academia, and it went quite well for a thirty minutes as examples of “expelled” people were presented. “OK”, I thought, “maybe there really are cases of unjust firings” though Stein wasn’t offering any detail on what those people exactly wrote to call the wrath of the academia upon themselves.

Then a familiar problem, familiar from every discussion of evolutionary theory versus religion, surfaced: without even a glance to what evolutionary theory is, Stein focused our attention on our (I’d like to add “current” and “relative”) ignorance on how life began, presenting it as the fatal weakness of the theory. Here are two facts:

  1. Evolutionary theory is not about how life began, it is about how it evolved once it (replication, variation and selection) has started.
  2. There are respectable scientific theories dealing with the origin of life, compatible with the evolutionary theories. We just don’t know which (or either) one is true yet.

So if you have a problem with our current state of knowledge about the origin of life, it’s not evolutionary theory you are opposing, it’s the scientific method in general. By the way, it is ironic that Stein tries to humiliate those theories by asking “Crystals? Aliens? I thought we were talking about science!” since the directed panspermia theory he calls “aliens” actually points to a physicalistic kind of intelligent design; the kind that most ID proponents are obliged to acknowledge in order to be politically correct by saying “We’re not all about God! Any kind of ID is OK!” The idea that the earliest forms of life on this planet were designed by some other sophisticated life form (which is itself evolved) from another planet is a defendable scientific position even if it’s not very strong against Occam’s Razor and apparently not very interesting for the ID people.

Modern science (on the left) stands no chance against the sophisticated ID people.

Modern science (on the left) stands no chance against the sophisticated ID guys.

After the false alarm of crisis I wasn’t surprised to see the next familiar move: evolutionary theory isn’t a good theory because it brings moral corruption! First, we are left to agree with the self-evident fact that life can only get its meaning from religion and wonder why all those atheist people are still alive. Then we are ready to meet the masters of science: Nazis and eugenics. I’m not going to argue about the degree to which Hitler was motivated by his misunderstood and misguided version of the evolutionary theory, because it has NOTHING to do with the scientific questions and theories in question! Likewise, the possibility that learning about the evolutionary theory might take away the precious meaning of our lives – whatever that is – has nothing to do with its being true or false!

Very well, but since it’s certainly true that the eugenics movement was influenced by the theory (mixed with other ideas), isn’t it hypocrite of us to ignore it while blaming religion for all the wars and terrorism it caused? No, because religion is largely a system of ethics telling people what to do, hence responsible for their actions, whereas scientific theories are just descriptions of what is out there, bearing no implications on what to do. This is one of the most important differences between religion and science in my view, and one that is often forgotten. Evolutionary theory is just a description of how life on Earth has been evolving, and is not responsible for the actions of some deluded people who misinterpret it as a to-do list.

Now let’s ask some questions: why does someone spend ten whole minutes to go into the details of how Jewish people were killed in a documentary about Intelligent Design? Could that be because he is too ignorant, like eugenics proponents, to know the difference between science and ethics? Or is it because he is smart enough to manipulate people’s feelings to make his case on scientific questions? I’d go for the latter since that someone is also very keen to flatter the nationalist pride, using his every chance to mention the great “American dream” of freedom to defend the freedom to toy with the definition of a scientific theory. Either way, Hitler is a wise choice to strengthen the oppressive regime metaphor with all the imagery from Nuremberg Rallies; somebody had to do this after Richard Dawkins’s comments in Root of All Evil? on Ted Haggard’s ceremonies. (Not to mention the other wise choice of make-up and lighting which turned Dawkins into Dracula in his interview by Stein. I found it particularly cheap that all we see are Nazi soldiers, crappy scenes from old black-and-white science-fiction films, old books on Darwin’s bookshelves and a marble statue of him whenever Stein talks about the evolutionary theories while the ID guys get to talk over colorful 3D models of DNA in their cool, nicely illuminated labs. His short parody of the film shows that Dawkins isn’t also happy with the way his words are cut.)

Expelled would have been taken more seriously by me (and maybe by the “oppressive science lobby”) had it played the “it’s not about God, we argue for any kind of ID” card all along and explored the expelling cases in more detail. But we know that the possibility of the intelligent designer being something other than God (“Aliens?”) isn’t scientific enough for Stein. Instead, he goes off track by declaring the issue of origin of life as the crisis of the evolutionary theory, by playing irrelevant emotion/ethics cards and by invoking religion as complementary to science. Seeing all those dirty tricks, one starts to wonder whether the superficial presentation of the so-called expellings was a wise choice too. Those people can check out this website by the National Center for Science Education for some insight into the cases.

Expelled is not so much a distress call for ID as an amateur attack on modern science. It is too much authored even for an authored documentary, and is a bad one even for a subject like Intelligent Design.
