| summary | teven Pinker tackles some of the biggest questions in psychology and sociology (How did humans develop the capacity for abstract thought? Will we ever understand what it means to be self aware? Why do we fall in love?) from an evolutionary biology perspective. This book makes some worthwhile points on the nature/nurture debate. |
Book reviews often start "If you only read one book this year...", but considering the slashdot readership, I'll amend that to: "If you only read one non-fiction book not published by O'Reilly this year, this one would be a good choice." The second chapter is about computers, and the second to last chapter is about sex, so a geek's gotta love it.
Though to be honest, the computer bits aren't terribly technical. They focus on the computational theory of the mind, and how as a theory, it gives us a useful, but woefully incomplete understanding of the human mind. There is, however, a fascinating technical explanation of stereo vision and how stereograms (magic-eye pictures) work, why some people can't see them, and a great explanation of how to do the trick with your eyes that you need to see them - the stereogram in the book is the first one I've ever been able to see, and it's almost worth the cover price just for that.
Reading Stephen Pinker, I always get the impression that his style comes from years of trying to keep his first-year university psychology class awake on a Monday morning at 9am. He does this with a combination of some very challenging ideas and highly entertaining writing.
In the first chapter, he makes the somewhat radical claim that innate biology has an equal, if not greater role than culture in shaping our desires, thoughts, and actions. He then spends the next 500 pages convincing us with a combination of well reasoned arguments and the results of rigorous scientific studies. He is, however, careful to remind us regularly of the limits of scientific enquiry, and of how much we still don't know "Virtually nothing is known about the functioning microcircuitry of the human brain, because there is a shortage of volunteers willing to give up their brains to science before they are dead." (p. 184)
His main thrust throughout much of the book is to debunk the "natural = good" equation that is quoted to so often these days. Aggressiveness, for instance, especially in male humans, is 'natural' in the sense that it was once adaptive (i.e. a trait that allowed it's organism to reproduce more successfully). Aggressiveness, is therefore 'natural' to male humans. This doesn't mean that men "can't help" being aggressive, or that men who beat their wives are somehow not at fault because it is "in their genes". As Pinker puts it:
Having explained how the brain thinks and how the eyes see, he goes on to consider how the capacity for emotion may have been adaptive (and therefore selected for) in our early evolution, and starts with a great example: "the yuck factor". We get a very cool theory of why we find certain things disgusting, why what's considered disgusting is highly cultural, and why the thing that elicits the strongest "yuck factor" response is food."...happiness and virtue have nothing to do with what natural selection designed us to accomplish in the ancestral environment. They are for us to determine. In saying this, I am no hypocrite even though I am a conventional straight white male. Well into my procreating years I am, so far, voluntarily childless, having squandered my biological resources reading and writing, doing research, helping out friends, and jogging in circles, ignoring the solemn imperative to spread my genes. By Darwinian standards I am a horrible mistake, a pathetic looser, not one iota less than if I were a card-carrying member of Queer Nation. But I am happy to be that way, and if my genes don't like it, they can go jump in the lake."
The first six chapters have covered key aspects of the human condition:
| Chapter 1: The Standard Equipment | talks about how the brain is wired |
| Chapter 2: Thinking Machines | covers the "human mind as computer" and the computational theory of the mind |
| Chapter 3: Revenge of the Nerds | explains Pinker's theory of how early humans prospered by exploiting what he calls the "cognitive niche" |
| Chapter 4: The Mind's Eye | explains the role that vision, and in particular colour, stereo vision as one of the factors that allowed humans to evolve such prodigious brain-power |
| Chapter 5: Good Ideas | is about how we use logic, comparison, and statistics in interpersonal relationships |
| Chapter 6: Hotheads | deals with the gamut of human emotions from altruism to envy |
All this has laid the groundwork for the second to last chapter, which he calls "Family Values". Some theories in the social sciences claim that people are born as virtually "blank slates" and that their upbringing, socialisation, education, etc. accounts for the way they 'turn out'. Criminality, substance abuse, and even the more petty human failings such as greed and vanity are assumed to have psychological underpinnings that come from one's childhood experiences. Pinker claims instead that some parts of the 'dark side' of being human is genetically encoded. He emphasises that this does not in any way excuse anti-social behaviour, but is simply another way of looking at what our conscience is up against when we feel the urge to take the credit for another's idea, sneak onto the subway without paying, help ourselves to the larger piece of cake, or cheat on our partner.
It's a long book, and it may take a little perserverence to get though it, but it's worth the effort because Pinker's ideas are interesting, challenging, and thought provoking. I don't agree with everything he says, and I think he sometimes over-simplifies an example to the point where it's no longer valid. Often, I found myself thinking "But human being are more complicated than that!" when he was explaining some facet of modern human behaviour in terms of the selection pressures of hunter-gatherers on the savannah. But all-in-all it is well worth reading. And at the end of it either you'll be able to see stereograms or you'll know exactly why you can't. To pick this book, head over to Amazon.
Big Assumption (Score:1)
for example, if we take the lungs. you can look at it in two ways.
the mechanic (i.e. scientist) looks at a lung, and makes a machine
which has a pair of balloons, and a diaphram to expand and collapse
those balloons based on the principle of air pressure. as the
articulated branching structure expands and collapses, air is
pumped in and out. they determine the air flow as a by-product of
movements from without created by mechanical processes. then they
say they have made a lung. but this entirely leaves out of the
question how a real lung could put all their technical knowledge
to shame by virtue of the fact that a real lung has no engineers
building it up from outside, but rather it GROWS without any
external assembly-type process (even with nanotechnology, the
assemblers are still just smaller external machines, not actually
growing like a real lung). if the scientists tinker with
biology enough, they find a way to redirect the growth to their
purposes, but they still don't fundamentally know WHY it grows
any more than they know WHY gravity makes massive objects attract.
now, looking at this another way - within the lung, the air flows
move in and out of the lung in a cyclic fashion. the air moves
through the lungs rhymically, and distributes in a branching
pattern to meet up with the air sacks in which the oxygen is
exchanged into the bloodstream, and then is breathed out again.
now, imagine if you will this air pattern continuing to flow in
cyclic fashion without the attendent lung apparatus through
which it flows. i.e. air flowing in and out of lungs in exactly
the same shapes and patterns, with the lungs themselves not present.
if you could imagine water flowing into and out of the branching
structure, and leaving a small deposit of sediment with each
cycle of the breathing, you would find that the lung structure
would slowly begin building itself up from the very process of
the breathing itself! you could then say: "the movement exists;
and the organ forms around it."
this is analagous to the fashion in which i believe the universe
is composed. the LIFE consciousness exists, the strucuture of
the universe forms around the life process as a by-product of
life's activities (think of the development of a baby in the
womb - just *what* directs this development? scientists, at a
loss point to DNA, but who coded the DNA which takes thousands
of scientists years and years just to figure out the code, and
still have no idea how the code is translated into the dynamic
process of organ formation - if it takes intelligence to decode
it, how can we say it was created by random permutation? it is
about as ridiculous as to say that enough monkeys typing at
random will regularly output highly intelligent novels and
scientific papers). similarly, *thinking* is not an attribute
of the brain, but rather the brain's structure and electrical
activity is determined by pre-existent THOUGHTS. the course
of evolution is not determined by CHANCE as the darwinists
would suppose, but rather -- changes in evolution are a natural
outcome of a change in configuration of life consciousness
itself - or put another and somewhat more poetic way: the
universe is the outworking of god's thoughts. the fine tuning
then is therefore not "amazing" at all, but rather to be
expected. it just depends on which side you approach the
problem intially: matter on up, or vice-versa.
the funny thing is the person sitting here ("you"), typing
into a keyboard can't explain his own thoughts or existence
by empirical methods - because consciousness cannot be proven
empirically. you simply know you exist. but only once you
exist can you look for a reason for WHY you exist. so again,
science is at a complete loss to explain the WHY of life,
even if it is very clever at explaining that when a cow
kicks a can, the can tips over. but they don't know WHY
the cow wanted to kick the can in the first place.
(this, of course actually goes on into a discussion of
thoughts, and if all thoughts are simply an: i) input,
ii) black box, iii) output - type of unconscious reaction.
but that ignores the fact of what happenes when one *chooses*
to respond in full conscious awareness to what proceeds in
the thought process. the tricky thing about consciousness is
that you can observe your own thinking, and even stop it
and who is doing that!?).
the assumption that the aggregate
organisation of complex molecules leads to a development
of consciousness as an attribute of the complex organisation.
but that still is far from being demonstrated in any way. in fact, it has failed in the utmost to explain the actual observed facts.

I'm actually even thinking to myself whether Pinker translated it and adapted it to his words. Even the part about aggressiveness being part of human nature has been said by Laborit. The stuff pretty much resembles Laborit's claims, except that Laborit wrote his book in 1973. Not only does he make the "radical claim" of how much biology influences our actions, he even goes so far as saying that it dictates our actions and that, in fact, we don't really have any "freedom" in our choices more than an electron has of turning around a nucleus.

Why fossils? We have living examples in reptiles, amphibians, and fish like the Siamese walking catfish.
What makes you think that we won't find the fossils of which you speak, let's just think for a moment, the oldest land animals we've found are in the hundreds of millions of years old.

I didn't realize anyone besides Searle actually still clung to that argument.
You should read some of Hofstadter's (or even Pinker's) material regarding The Chinese Room--I think you'll find that in order for Searle to be as wrong as he is, he'd almost have to be trying to deliberately mislead people.
The basic counter-argument is: The whole analogy is false since it presupposes a homunculus in my brain that does the understanding "for me". I think it should already be obvious that "understanding" is not the function of some part of the brain, but a whole brain function. Thus, mapping back to the Chinese Room we might be able to say that the entire system (man, books, paper, pencils, door, etc) does in fact "understand" Chinese.
Of course, the many many concommittant "implementation" problems of Searle's formulation make this a difficult proposition at best. For instance, just how big would The Chinese Room have to be? And how long would it take the man inside to craft a response?
BTW, neither Dennett nor I am a "functionalist" if by that you mean "operationalist".

We know next to nothing at this point in time about the genuine biological causes (if any) of aggression and other human behaviors. Certainly one can postulate an evolutionary origin for them, but really this is no more "scientific" than traditional psychological explanations for aggression such as bad childhoods or too much movie violence. If we can find a series of genes involved in aggression *and* we can find versions of these genes in other animals *then* we can have meaningful research into the evolution of aggression. This is the level of evidence required by modern biology. Until then the subject belongs more to science fiction than science.
As a biologist who has written papers concerning molecular evolution, it worries me that from books like "How the Mind Works" and "The Moral Animal" the general public thinks evolutionary biology is nothing more than coming up with cute stories. No wonder Creationism is still thriving -- if people think evolutionary biology is just a matter of cute stories they feel free to choose another cute story instead.

The popular anti-nativist work is _Educating Eve_, by Geoffrey Sampson. Unfortunately, both sides of this debate use very poor scientific arguments. The "argument from lack of data" (note the medievalist-sounding name) is a fine example: Nativists (Chomsky etc.) claim that there are insufficient data available to a child learning a language, particularly with regard to incorrectly-formed sentences (the child never hears someone being corrected for saying "the the the an orange chimpanzee", yet still knows it's wrong). Therefore, there's got to be some innate knowledge. The empiricists (anti-nativists, in this case) claim that grammar is the "simplest" explanation of the sentences presented to the child, so it gets selected.
But both sides present depressingly unscientific arguments! You'd think someone would go out and CHECK what children actually hear, but Sampson gives an example where Chomsky couldn't possibly have seen data for what he's claiming (creating the yes/no question for a sentence; you need to ask about the main verb, not about the first verb, and Chomsky claims that most children won't have heard a single example). Sampson gives examples of plausible sentences which would settle the matter. Of course, neither side has bothered to check it in the field.
But still, the empiricists seem to have it right

They tend to be modularist in their perspective - claiming that the ability to perform syntax is a product of the development of specialized structures that organically develop to do them.

Also, Chomsky/Pinker et al tend to leave semantic ability out of the picture.
Structured connectionism offers a plausible explanation for semantic ability - see Terry Regier's "The Human Semantic Potential" for some viable models using neural networks, that do excellent jobs of understanding, for example, the difference between "on," "above" and "over" with fairly quick learning, and distinguishing between the German "auf" and "an".

Let me just point out to you that current computer models of neural networks are not quite the same as animal brains. Computer connection machines like neural networks are all synchronous and therefore deterministic. They are actually Turing machines. However animal brains are asynchronous and chaotic, not deterministic. They are not Turing machines and may therefore compute things that Turing machines may not compute.
However, computer neural networks can serve as a useful and illustrative schematic model of how some low-level structures (cell assemblies) in "wet" neural networks do operate. This much has been proven experimentally.

Oh how typical. It seems that there are people brought up in your culture who are completely unable to think from any other perspective than 'guns are good'.
Why don't you try reasoning for once.
(1) In any society there is always a small proportion of lunatics and wired misfits.
(2) A lunatic with empty hands or even with a knife is dangerous but a lunatic with a gun is an order of magnitude more dangerous in terms of the number of people he can kill before he is forced to stop.
(3) If guns are generally available in society, anyone will be able to get one if they want to; the law just means they have to steal one or buy one illegally.
Therefore - and for the hard of thinking, it really is this simple - if you make guns generally available then you will always see atrocities like this.

Organisms transmit their biological characteristics to their offspring. That is why your children look like you, and that is why selective breeding of domestic animals has been successfully practised for millennia. Genetics has even become an applied science at the molecular level. To deny the validity of this theory is to deny the evidence of your own eyes. It isn't even worthy of debate. By the way, the 'father' of genetics, Gregor Mendel, was a monk.
Natural selection merely states the obvious fact that those organisms who produce no offspring having died young or having been unable to win a mate, will not transmit their biological characteristics to the next generation. Natural selection certainly was and continues to be a major factor in the way species evolve, because ultimately it is only a description of this obvious and observable fact about population dynamics. By the way, Charles Darwin was a deeply religious man throughout his whole life. If you really read his writings you would know this.
I don't deny the possibility of God's existence. I'm not even going to argue about the likelihood (or not) of His Direct and Personal Intervention in the evolution of species on this planet as it would take up too much space. Let's just agree that it can't be ruled out. But whether he did or didn't intervene, evolution would still have happened by the ebb and flow of population dynamics modulated by changing environmental conditions (like climate) and spiked by the very occasional random mutation. We know from common experience and experiment that all these things happen and we also know that when they do they affect the shape of successive generations.
Where does that leave God in terms of a role in evolution? As a 'God of the Gaps'. I don't have any particular philosophical difficulty with that although some do. But throughout history, as these gaps in our knowledge have been progressively illuminated by new discoveries the God of the Gaps has like the darkness been steadily driven away.
At the end of the day I doubt I can convince you because the only line of reasoning that can sustain a viewpoint like yours is a closed and circular one that denies all experience and all logic. But think on this:
There is an epistemological viewpoint that the 'truth' of any theory cannot be regarded as an absolute because we can never know everything there is to know, and some as-yet-unknown fact may just be lurking around the corner waiting to overturn the applecart of that particular theory. Therefore we can only evaluate theories in terms of how useful they are - not merely in providing an explanation of our observations, which could be a false explanation - but in terms of whether they allow us to make accurate predictions of that which is not yet known directly, and in terms of whether the theory can be applied to create new useful technologies.
The scientific community admits that the theories of evolution and the origin of life on Earth are not yet complete. However what is 'known' about them is enough to be usefully applied in selective breeding, genetic engineering and the treatment of genetic diseases. Moreover paleontology has been assembled into a successful and mostly self-consistent picture of biological history. Gaps and a few inconsistencies in the model at any given time do not invalidate the usefulness of the whole theory as long as most of its predictions continue to be in agreement with new discoveries.
What useful predictions and tricks can you or anyone else do with your 'theory'? You can't answer that, can you!
That is the real difference between a a community operating under careful peer review to develop a theory based on solid evidence, and a horde of self-deluded halfwits with a book of ancient fairy stories. Between fact, and fantasy.

Darwin's theory of evolution should result in several transitory fossils being found.
Ummm . . . no. It suggests that such transitory organisms existed at some point, but a theory of natural selection makes absolutely no predictions about which fossils must necessarily survive until the 20th century, or which surviving fossils must be found. If such fossils have not at this point been found, that does not prove that they don't exist. I never heard of Columbine High School until this morning. So what? It existed anyway.
I really don't know whether fossils of that sort have been found or not, because I don't follow paleontology very closely.
Finally: Like a lot of theories, evolution is the best explanation that we have for the facts available to us. It makes a hell of a lot of sense. Also like all theories, it's probably not perfect. Do you know how many theories have come and gone trying to explain the building of mountains? The one we've got now looks pretty good, and I'm betting that it will turn out to have been substantially accurate, but no responsible geologist will tell you that he knows the absolute and final truth about it. This is where religion and science part ways. Religion demands a "final truth"; science does not. This is where creationists are coming from when they criticize evolution: They see a discrepancy somewhere, and they conclude that therefore the theory is not the absolute final truth. As religion, evolution is therefore unacceptable. So they reject it. The problem is that it isn't meant to be religion. It's science. Scientists aren't looking for an infallible moral compass, they're just trying to explain what they've observed as best they can.
Evolution fits the evidence reasonably well, while creationism requires us to ignore a massive body of evidence. As for me, I'll go with the one that doesn't ask me to forget half of what I know.

- Kids at that age are incredibly cruel. The pointless insults that adults hold in check are often not held back during adolescence. Humor at the expense of others (because they wear a black trenchcoat, for instance) is easy to add to the "warchest" and is not a tool only for jocks.
- A society that glamourizes adult desires (sex, power) while simultaneously limiting their adult privileges (drugs, alcohol, driving, the ability to make money).

Programming The Trenchcoat Brain (Score:2)
As for the tragedy yesterday and how an understanding of it can be approached from an "evolutionary psychology" perspective, I'll take the first stab at it:
After immediate survival, the next most important goal of the human psyche is to increase social status among peers, which in turn results in increased mating opportunity. There are many tools in the "mental warchest" that humans employ to achieve this goal. Arguably, it is for these very reasons that the human brain has exploded in size over the last million years or so (see Dawkins, Unweaving the Rainbow): Not as a tool of survival in "the wild", but as a tool to manipulate and influence other humans.
The willingness to employ physical violence is one of the natural tools with which we are endowed; particularly among men, there is a certain thrill to the kill of another man, powerful, confidence inspiring, and impressive amongst others (usually both male and female). Witness professional sports, or Quake: A stage upon which to play out all of the symbols of violence, without the actual death. Why do we love to play out these symbols? Because jocks get laid.
And these kids didn't get laid. (Seen their pictures?). And they targeted jocks in their killing spree.
Consider what would have been the outcome of their carefully planned attacked in the "ancestral environment", in which your world consisted of 100-200 persons, all of whom you knew and would likely live your entire life with.
The jocks, who had all of the mating opportunity in your little community, would be conveniently removed from society, while at the same time the killers would wear new mantles of (fearful) respectability.
From natural selection's standpoint, what happened yesterday was a viable and intelligent career move.
From "our" standpoint, however, the evolutionist's mantra must be repeated: " "is" does not mean "ought" ", in other words, to say that we ARE a certain way (in a "natural sense") does not mean we SHOULD be that way, or that we SHOULDN'T bother to try to work against our "natural" inclinations in order to foster a more amicable society. This is why we have laws, against killing for example.
Reason clearly shows anyone who reflects upon it that the "strategy" employed yesterday, although instinctive and "natural" from an animal sense, would be pointless in modern society, in which we have arranged things such that those who commit physical violence are guaranteed to have zero future mating opportunity. And, not seeing any other solution to their "problem", they concluded that their own lives were not worth continuing, thus ending the day in suicide.
There, I hope I have done a decent job "spinning" yesterday's awful events in a style congruent with Pinker's "How the Mind Works". If anyone else (who has actually read the book, please!) can do better, I'd love to hear it.

No, no, no. The smaller your school is, the more likely people won't be able to find a group they can be part of, be comfortable with. If I go to a school with, say, 100 people, and 99 of them are total tools -- sports, pop music, GAP jeans, the whole nine yards -- am I, as a nonconformist, more likely to turn into a conformist and join your "closer student body" or am I more likely to just hate and fear all of the tools?
Or, conversely, if I'm in a school with 10,000 people in it, am I more likely to be an outcast and never find anyone that agrees with me or thinks like me, or am I more likely to find twenty kids who know where I'm coming from and like me?

Our tools didn't accept anyone who didn't fit one of their molds, they instead ridiculed them and cast them out. If you didn't play a sport, go to one of their churches, and agree with most of what they agreed to be truth, then you were only barely acceptable as a person, and you certainly weren't invited to be *friends* with them.
Also, there was more than one operative clique in the school. We also had this group who liked to feel different -- they listened to NIN and wore either black leather or flowers in their hair -- but had nearly the same rules as the preps. The significant change was that you didn't have to play a sport, but you had to have some feature that let them know how different you were.
My point is that stratification is going to happen no matter what the size of the student population is, but if it's bigger instead of smaller you don't get as many strata with only one person on them. My point is NOT that people only get along with people from their own strata, and should be closed minded to all others, please don't read it that way; I had friends and acquaintances that were totally nothing like me.
If you think that your small school is special, and that it's not like that where you're from, you might try a little ad hoc experiment of mine. Look around a crowded room, like your lunch room or some such, and pick out five people that you don't know very well or don't like. Tally all of the parties you've been at and they were there, all of the clubs/teams that you're both on, and all of your mutual friends. Now pick out five people you like and hang out with. Not your best friend or anything that might throw off the numbers, but friends. Add up the same number for them.
LOOK! The number for the strangers is far, far less than the number for the friends, because you are on different social strata! You might not consider those strangers bad people or worthless people, but they certainly aren't nearly as close as the people in your clique. Don't be ashamed of being in a group, be happy, you are cool enough, and a good enough person that you were able to go this long without even noticing the strata!

Meanwhile they "debunk" competing theories that do make testable hypotheses by portraying the failures in the worst possible light, portraying exceptional failures as the typical case, and using them as subject matter for jokes in order to ridicule them.
Meanwhile, if you start looking at the assumptions they build their own theories on -- if I may so stretch the use of the word "theory" -- it always turn out to be ungrounded intuitions and lame arguments of the "it must be the case" type.

Basically, they show that many of the functions that are supposedly impossible, and many of the strange patterns in learning which supposedly can only be accounted for by innate predispositions and knowledge can actually be simulated very well in neural networks which don't build in -any- knowledge of the subject area (e.g., they aren't born knowing Universal Grammar, yet Elman provides an example of a network which has managed to sort linguistic data according to grammatical category. This ability was not programmed in--it was independently learned by the network). Of course, all this is preliminary--we certainly don't have neural nets that can simulate human behaviour in total, or even close. But the assumption that we -need- innate knowledge to account for this type of stuff just doesn't fly.
An interesting point that Elman et. al. mention is that the genome just doesn't contain enough information to specify brain representations--it's not possible for this sort of knowledge to be encoded in the genes. 'Wiring of the microcircuitry'--i.e. specification of synaptic connections--'is essential if language, the quintessential higher cognitive process, is an instinct...' (Pinker, The Language Instinct, 93, 97). But, genetic prespecification of synaptic weights in the brain is just too much information for genes to carry--such specification could reasonably require on the order of 10 trillion base pairs of DNA just for our brain--and that's more than we have for our whole body.
Elman et.al. make another major contribution to the debate by describing an interactionist framework, where outcomes may be highly constrained and universal, but not themselves directly contained in the genes (or the brain) in any domain-specific way. (Notice that this is exactly the faulty inference of which Pinker and many other nativists are guilty.)
In sum, I think that Rethinking Innateness is an extremely valuable contribution to the old nativist/empiricist debate, most especially for their dissection of the concept 'innateness', which nativists use with abandon, but which really is ambiguous between a large number of possible interpretations.
