HUMAN UNNATURE:

Charity begins at Homo sapiens (Mark Buchanan, 12 March 2005, NewScientist.com)

IN THE aftermath of the Indian Ocean tsunami last year, people from the world's richest countries were falling over each other to make donations to help rebuild the lives of the survivors. Perhaps it was the conjunction of this terrible natural disaster with the consumerist orgy of Christmas that spurred so many of us to greater generosity. Whatever the reason, conspicuous donation suddenly became the vogue. Individuals, and even entire countries, competed to see who could send most money to people on the other side of the world whose identity they did not know and who they were highly unlikely ever to meet. What an odd species we are.

Not that Homo sapiens is the only species in which individuals bestow kindness on others. Many mammals, birds, insects and even bacteria do likewise. But their largesse tends to be reserved for their genetic relatives; this makes sense in evolutionary terms, because by helping someone who shares many of your genes you improve the chances of propelling this common DNA into the future. Humans are different, for we cooperate with complete genetic strangers - workmates, neighbours, anonymous people in far-off countries. Why on earth do we do that?

For several decades, researchers have had a possible explanation: apparently selfless acts are nothing of the kind, but are instead a clever way of promoting individual self-interest. When rivals meet again and again, for example, the rewards of cooperation can outweigh the costs of conflict, so getting along pays dividends. Scientists have also come to realise what philanthropists such as Getty and Gates have long known: that altruism does wonders for your reputation (see "Why are we so generous? - below"). But does cooperation always have self-interested roots? Some researchers are starting to have their doubts.

Over the past decade, experiments devised by Ernst Fehr of the University of Zurich in Switzerland, among others, have shown that many people will cooperate with others even when it is absolutely clear they have nothing to gain. A capacity for true altruism seems to be a part of human nature. [...]

Across disciplines, researchers now agree that people often act against their own self-interest. "This is the most important empirical work on the human sense of justice in many years," says evolutionary biologist Robert Trivers of Rutgers University in New Jersey.

But when it comes to explaining the origin of our altruism, matters get a whole lot more contentious. In evolutionary terms it is a puzzle because any organism that helps others at its own expense stands at an evolutionary disadvantage. So if many people really are true altruists, as it seems, why haven't greedier, self-seeking competitors wiped them out?


Yes, if you start with the wrong terms many things are puzzling.

Do we have to go back to Spencerianism for all the answers? Charity functions as a form of insurance--a "safety net," if you will, serving to facilitate innovation and mobility without the stifling hand of state power. It is just one one the many ways in which custom and religion contribute to progress.

The Libertine ideal of the economic war of all against all is actually counter-progressive, as the need for security against failure inhibits advancement.

So Sri Lankans will send us medicine if we have a crisis?

Posted by: oj at March 16, 2005 2:19 PM

There has to be a materialistic explanation. There just has to.

Posted by: Roy Jacobsen at March 16, 2005 2:27 PM

why is it so hard to believe/accept that some people are just good/nice ?

think about it this way: we have a pleasure center in our brains; doing things that stimulate that center reinforces certain behaviors; being nice feels good to some people. just that simple.

Dear Sri Lankans,

I would be happy to contribute to your relief efforts if you can demonstrate that my charity would directly benefit two of my sibling, or four aunts and uncles, or eight cousins. I am a magnanimous sort and thus will be happy to accept any combination thereof.

Yours, etc.

News Flash. Sri lankans are our genetic relatives.

And I'd be willing to bet that no one's charitable giving in this case is coming at even the tiniest risk to their continued survival.

(Michael Schumacher, one of those awful, secular, Germans, gave $10,000,000 to tsunami relief efforts last month. Wonderful? Yes. A true sacrifice? Perhaps not, since he has made roughly $60,000,000 per year for the last 10 years...)

Posted by: Jeff Guinn at March 16, 2005 8:35 PM

But obviously not ones much like us. Darwinism assumes competition within the species.If "evolutionary change comes about throught the abundant production of genetic variation in every generation. The relatively few individuals who survive, owing to a particularly well-adapted combination of inheritable characters, give rise to the next generation." Then is is obviously anti-Darwinian to help those who are differently adapted than you.

ghostc: sometimes a cigar is just a cigar :) doing good for its own sake doesn't necessarily have any deeper meaning or cause; it just is.

Posted by: cjm at March 16, 2005 10:22 PM

Mr. Judd;

It is only in very recent times that one could help non-kin {i.e. people not in the local tribe) this way. Social animals evolve at the deme level as well as the individual.

Posted by: Annoying Old Guy at March 16, 2005 10:53 PM

AOG:

Ah, the trusty old "Darwinism was true until us" meme.

Posted by: oj at March 16, 2005 11:04 PM

Kin are who you think they are. Globalization of trade, culture, travel, and immigration has helped to redefine the psychological categories of "us" and "them". You don't try very hard to find explanations, do you?

Posted by: Robert Duquette at March 16, 2005 11:44 PM

Robert:

The Just-So story is a Darwinian specialty. Of course racism is a survival response against those different than us, right? Hard to square all your little circles...

Posted by: oj at March 16, 2005 11:48 PM

How much did you guys give to the Filipinos, who were wiped out by the tens of thousands by weather at just the same time?

Nil, nada, nothing, not any, right?

If feeling better about yourself contributes positively to your survival (a position often advocated by Orrin), then dumping a few shekels on the Sri Lankans is easy enough to explain in darwinian terms, although not everything that is done has to have a darwinian explanation.

It's a whole lot easier to explain, though, how caring, altruistic Americans dumped their unsalable merchandise (like 20 crates of Maui Monkey dolls) on the long-suffering Sri Lankans and claimed a tax deduction from me.

Charity, indeed, begins at home.

Darwinism is the force that shapes all life in the universe but it's intermittent?


Philippinos did, BTW, donate quite a bit to Tsunami victims.

Posted by: oj at March 17, 2005 4:21 PM

"Darwinism is the force that shapes all life in the universe but it's intermittent?"

Perhaps you're thinking of the modern evolutionary synthesis, but yes, evolutionary change is sometimes faster, sometimes slower.

Posted by: creeper at March 17, 2005 5:50 PM

You mean it doesn't have to be gradual, with no major breaks or discontinuities? And there isn't abundant production of genetic variation in every generation?

Posted by: oj at March 17, 2005 6:01 PM

Yes it does, and yes there is, but the change resulting from it in terms of the living organisms changing over successive generations will proceed at varying speeds, sometimes faster, sometimes slower.

Posted by: creeper at March 17, 2005 6:13 PM

Incidentally, wouldn't a potential falsification of the theory of evolution be if a new species had showed up without any clear precedent? Something that had no anatomical similarity to a predecessor?

Posted by: creeper at March 17, 2005 6:20 PM

Like life itself?

Posted by: oj at March 17, 2005 8:26 PM

Not intermittent. Opportunistic.

I know you know this, because I've told you before.

Just reminding the lurkers to be aware how you distort the discussion.

Posted by: Harry Eagar at March 17, 2005 9:01 PM

So there are only certain "opportunities" where Darwinism functions? I don't need to distort--you guys are self-parodistic.

Posted by: oj at March 17, 2005 9:05 PM

"Like life itself?"

You're welcome to read up on the various speculations concerning abiogenesis at your leisure. I'm sure you're aware that the theory of evolution deals with evolution.

So: wouldn't a potential falsification of the theory of evolution be if a new species had showed up without any clear precedent? Something that had no anatomical similarity to a predecessor?

Posted by: creeper at March 18, 2005 1:21 AM

"So there are only certain "opportunities" where Darwinism functions? I don't need to distort"

You already did.

Posted by: creeper at March 18, 2005 1:23 AM

creeper:

No, not unless you think the only way life can arise at all is the precise way it did here. That's a tad teleological for Darwinsm, but it's exactly the kind of athropomorphism we expect of Darwinists.

Posted by: oj at March 18, 2005 7:57 AM

The theory of evolution does not state that the way things went is the only way they could have gone, and I'm not sure how you draw that inference from what I said.

What the theory of evolution does say is that organisms evolve gradually; a potential falsification would be to have something appear in the fossil record that is completely out of step - for example a centaur, without intermediate steps from either horse or man preceding it.

Posted by: creeper at March 18, 2005 9:49 AM

So it would be unsurprising to find that not all life descends from just one organism. Indeed, it's inexplicable under Darwinism that it is so descended.

Posted by: oj at March 18, 2005 10:20 AM

I'll read up on that, Orrin; for the moment I have no response pro or con.

Can I take it that you take the potential falsification on board?

Posted by: creeper at March 18, 2005 11:34 AM

That if all life on Earth--which is all advanced life in the Universe--comes from one just template then Darwinism is likely false? Yes.

Posted by: oj at March 18, 2005 11:38 AM

That is hardly what I posited. I was talking about inexplicable leaps in the fossil record.

As for us being the only advanced life form in the universe, that's an entirely different subject, which you introduced out of the blue, and which has nothing to do with this potential falsification.

Re. 'just one template', I'll get back to you on that.

Posted by: creeper at March 18, 2005 11:51 AM

If we found a fossil of a centaur, and there was no evidence in the fossil record preceding that particular fossil of any intermediary organisms between horse and centaur or man and centaur (or really anything preceding the centaur that resembles it), would you say that that disproved the modern theory of evolution?

Posted by: creeper at March 18, 2005 12:28 PM

Why would a centaur be anymore revealing than the eyeball the hand etc.

Posted by: oj at March 18, 2005 12:46 PM

You raise some rather interesting implications that have as a consequence that the claim one hears occasionally (even on this blog) that evolution is not falsifiable and hence not science is actually null and void.

I take it for now, based on what you just said, that you agree that finding fossils of a centaur under the aforementioned conditions would in fact disprove evolution.

Do you disagree?

Posted by: creeper at March 18, 2005 3:09 PM

No. Darwinists can make them fit the theory.

Posted by: oj at March 18, 2005 4:32 PM

Posted by: creeper at March 18, 2005 4:57 PM

The current fossil record disproves it. What would the centaur fossil add?

Posted by: oj at March 18, 2005 7:55 PM

I didn't say anything about the Filipinos did. I said you did not behave altruistically toward the suffering Filipinos.

Balances out, I guess, in your crazy version of evolution.

Selection is not like sin, where one slip settles everything. It is opportunistic.

You can cross a busy street against the light, and you might not be selected against the first time. But if you keep at it, the chances you will be selected against rise quickly.

Jesus didn't get variation, but he did get that. Even he.

Posted by: Harry Eagar at March 18, 2005 8:00 PM

The "suffering Filipinos" were sending vast amounts of money to tsunami victims.

Posted by: oj at March 18, 2005 8:07 PM

Orrin,

So I take it for now, based on what you just said, that you agree that finding fossils of a centaur under the aforementioned conditions would in fact disprove evolution.

What in the fossil record disproves the modern evolutionary synthesis?

And please try to be coherent: either evolution is unfalsifiable or it has been disproven. You can't claim both.

Posted by: creeper at March 19, 2005 3:44 AM

Why not?

It's unfalsifiable from within, obvious nonsense frrom without.

Posted by: oj at March 19, 2005 9:07 AM

What in the fossil record disproves the modern evolutionary synthesis?

Posted by: creeper at March 19, 2005 10:01 AM

"Why would a centaur be anymore revealing than the eyeball the hand etc."

Because in the example I named, the centaur would have no anatomic precedents.

Posted by: creeper at March 19, 2005 10:06 AM

No anatomic feature has precedents.

Posted by: oj at March 19, 2005 3:40 PM

I've noticed when you make claims like this -

"The current fossil record disproves [the modern theory of evolution]."

- you avoid the inevitable question to back that up with facts or specifics with remarkable consistency.

Posted by: creeper at March 19, 2005 3:44 PM

i just ex0plained it: there is no precedent in a one-celled organism for anything that followed.

Posted by: oj at March 19, 2005 3:47 PM

My apologies, I had not seen your post from 3:40 when I hit 'post' on mine.

A one-celled organism is a precedent for a multi-celled organism, which in turn, by many small degrees in different directions, became the precedent for everything that followed.

Posted by: creeper at March 19, 2005 4:26 PM

Even you must recognize how inane that is. But accepting it has some validity for the sake of argument then the centaur is implicit in the one-celled organism.

Posted by: oj at March 19, 2005 4:31 PM

Evolution from single-celled to multi-celled organisms and from there to the variety of life around us is hardly inane, and can be followed gradually throughout the fossil record.

Be that as it may, if a centaur showed up in the fossil record, with no intermediate stages preceding it that connect it to either horse or man, that would be a pretty powerful refutation of the theory of evolution. Much as you like to beat around the bush, I take it based on your previous statements that you're inclined to agree with that.

Posted by: creeper at March 19, 2005 4:47 PM

No, it can be folowed in some instances by leaps. Mostly it's just hypothezied about. The two-celled organism is more different than the single than a centaur differs from a horse.

Posted by: oj at March 19, 2005 5:33 PM

I don't know if this is part of the theory of evolution, but there are theories that plausibly explain the transition from prokaryotes to eukaryotes.

A centaur found without predecessors in the fossil record, however, would have evolutionary biologists stumped.

Posted by: creeper at March 21, 2005 3:45 AM


It has predecessors.

Posted by: oj at March 21, 2005 8:11 AM

My point was that if something occurred that did not have any predecessors in the fossil record, so how about we posit a centaur showing up in the fossil record before either man or horse showed up - that would be a falsification of the theory of evolution.

Posted by: creeper at March 21, 2005 10:41 AM

Why? If man and the horse are implicit in the single cell so is the horse/man.

Posted by: oj at March 21, 2005 10:59 AM

The point is that if, say, the centaur shows up in the fossil record without any predecessors (ie. if horse and man show up after it in the fossil record), then that would be a refutation of the claim contained in the theory of evolution that organisms evolve gradually.

Posted by: creeper at March 21, 2005 11:18 AM

creeper:

Y'all would just claim that man and horse had diverged from the man-horse.

Posted by: oj at March 21, 2005 11:30 AM

Most likely, and given those hypothetical circumstances, that might then well be true - but the point is not what the man-horse subsequently turned into.

The point is if there were a centaur in the fossil record with, for example, either nothing or just some simple eukaryote structures preceding it, it would be a powerful refutation of the theory of evolution, and a strong argument in favor of some kind of Creationism or Intelligent Design.

Posted by: creeper at March 21, 2005 12:11 PM

Yes, except that there's no precedent for anything in the fossil record and that doesn't phase you guys. Faith isn't rational.

Posted by: oj at March 21, 2005 12:14 PM

Ah, there's no precedent for anything in the fossil record, I seeeee...

Posted by: creeper at March 21, 2005 12:48 PM

Yes, the one-celled organism was complete and perfect.

Posted by: oj at March 21, 2005 1:11 PM

Then why didn't the Designer stop there?

Posted by: creeper at March 21, 2005 2:39 PM

One-celled organisms don't have souls or free wills.

Posted by: oj at March 21, 2005 2:43 PM

"there's no precedent for anything in the fossil record"

You really should read this sometime.
