Fruit Flies and Free Will

Posted in Science on May 20th, 2007 by Chip Gibbons

A recent experiment with fruit flies has some important implications for the idea of free will.

“Neuroscientists have been claiming free will doesn’t exist,” said Bjorn Brembs, a neurobiologist of the Free University Berlin in Germany who led the study.

The claim is based on work in the 1980s by neuroscientist Benjamin Libet of University of California San Francisco, who discovered that even before a person made a conscious decision to move, the brain had already started the process of movement.

Neuroscientists say this so-called “readiness potential” suggests that the brain simply responds to outside stimuli, and consciousness is just the brain’s way of rationalizing actions the brain has already determined to take.

[…]

Animals, and particularly insects, are often seen as complex robots, responding only to external stimuli, said Brembs, whose work appears in the Public Library of Science journal PLoS One.

The researchers placed a single fruit fly in a pure white chamber — devoid of visual cues. The fly was fixed in place and its attempts to turn were recorded. Researchers repeated their experiment on many flies and analyzed the data using a series of complex mathematical models.

What they found was surprising.

Lacking external input, Brembs said he had expected a pattern of entirely random movement or noise — akin to static on a radio that is tuned between stations. Instead, the flies showed a pattern of flight that was generated spontaneously by the brain and could not have been random.

“The decision for the fly to turn left or turn right, which it changes all the time, has to come from the design of the brain,” Brembs said.

Brembs said the finding reveals a mechanism that could form the biological basis of free will.

“I don’t think we’ve found consciousness in the fruit fly,” he said. “It’s like one of the first building blocks, without which you can’t go on.”

Quotes of the Day

Posted in Quotes, Religion on May 18th, 2007 by Chip Gibbons

“If you’re not a born-again Christian, you’re a failure as a human being.”

“Christians, like slaves and soldiers, ask no questions.”

“I am such a strong admirer and supporter of George W. Bush that if he suggested eliminating the income tax or doubling it, I would vote yes on first blush.”

“You know when I see somebody burning the flag, I’m a Baptist preacher I’m not a Mennonite, I feel it’s my obligation to whip him. In the name of the Lord, of course. I feel it’s my obligation to whip him, and if I can’t do it then I look up some of my athletes to help me. But, as long as at 72 I can handle most of the jobs I do it myself, and I don’t think it’s un-spiritual. When I, when I, when I hear somebody talking about our military and ridiculing and saying terrible things about our President, I’m thinking you know just a little bit of that and I believe the Lord would forgive me if I popped him.”

“You’ll be riding along in an automobile. You’ll be the driver perhaps. You’re a Christian. There’ll be several people in the automobile with you, maybe someone who is not a Christian. When the trumpet sounds you and the other born-again believers in that automobile will be instantly caught away — you will disappear, leaving behind only your clothes and physical things that cannot inherit eternal life. That unsaved person or persons in the automobile will suddenly be startled to find the car suddenly somewhere crashes. … Other cars on the highway driven by believers will suddenly be out of control and stark pandemonium will occur on … every highway in the world where Christians are caught away from the drivers wheel.” (from Falwell’s pamphlet “Nuclear War and the Second Coming of Christ”)

American Idol Surprise

Posted in Bainbridge Island, Music, Television on May 16th, 2007 by Chip Gibbons

Melinda Doolittle, who was easily the most polished and consistent singer on this season’s American Idol got voted off tonight, leaving Jordin Sparks and Blake Lewis to duke it out in the final.

Melinda’s got a great career ahead of her even though she didn’t win. People might have been reacting against Simon’s obvious love of her by voting for the other candidates instead. Since many people probably expected that she would be in the finale, they may have concentrated their votes on the person they wanted to compete against her. That would have given a lot of votes to Jordin and Blake and left Melinda high and dry.

In my perfect world, Melinda and Blake would have been the finalists, but this was not to be. Now I think the finale will be a bore.

The good news is that Blake’s chances of winning the contest just went up with Melinda out of the picture. And as I said before, Blake is an original and also a polished performer. I don’t think Jordin can beat him, although there are some who think that those who voted for Melinda are more likely to vote for Jordin at the finale. I can see that logic because I thought that Blake would be booted off this week because LaKisha’s voters would be more likely to vote for Melinda and Jordin this week, but that didn’t happen.

If Blake can pull off some eye-catching numbers at the finale, he will stand out and Jordin will be just another female singer with a great voice, and the field is already so crowded with them.

Paula Abdul certainly got it wrong when she said that Seattle had the “best delusional” singers. (She appeared to be under the influence of something when she said it.) Both Sanjaya and Blake are from the Seattle area and they both did well. Now, I’ll be surprised if Blake doesn’t win.

Check out the Seattle-PI article on Blake’s rise to the top. They also point out that both Jordin and Blake auditioned in Seattle.

Jerry Falwell Dies

Posted in AIDS, Gay Interest, Religion on May 15th, 2007 by Chip Gibbons

Today was a beautiful, unseasonably warm day in Seattle. The temperature hit 83. This little taste of nice weather is long overdue and people were out and about enjoying themselves. It seemed like so many had a smiles on their faces.

It was in the afternoon that I heard the news that Jerry Falwell died today at 73. My immediate reaction was one of joy, but I refrained from running up and down the sunny streets of Seattle, shaking hands, hugging total strangers, singing out loud or going into gay bars and proposing a toast. My joy was followed by some sadness, mostly for all the people that Jerry Falwell had harmed in his life, and for Falwell himself, that he had lived a fantasy for his entire adult life, never understanding the real beauty and majesty of existence.

I was sad for the millions who have died of AIDS, never having the chance to live the 73 years that Falwell lives because Falwell and other religious leaders did everything they could to frustrate scientific research into HIV/AIDS in the crucial early years of the epidemic. Had our understanding of the disease grown faster, many more lives would have been saved and many more people would not have become infected. But to Falwell and other religious fanatics, AIDS was God’s punishment for homosexuality, and therefore it should be allowed to continue its rampage across the planet.

I totally agree with this quote:

Matt Foreman, executive director of National Gay and Lesbian Task Force, extended condolences to those close to Falwell, but added: “Unfortunately, we will always remember him as a founder and leader of America’s anti-gay industry, someone who exacerbated the nation’s appalling response to the onslaught of the AIDS epidemic, someone who demonized and vilified us for political gain and someone who used religion to divide rather than unite our nation.”

That would be appallingly slow response. We can’t know for sure, but he probably helped to kill more people that Hitler killed in concentration camps when you get right down to it. Had discovery of HIV and the drugs that have proven so effective against it taken place even a couple of years sooner it would certainly have saved millions of lives and kept millions of others from getting infected.

I’m sure that many people who were close to Falwell are saddened by his passing. I cannot even begin to put into words the sadness and grief that many of us experienced in San Francisco during the first 10-15 years of the AIDS epidemic as we not only had to watch so many young friends die but also had to endure the relentless insults and hatred of people like Jerry Falwell.

As for homosexuality, Falwell remarked, “AIDS is the wrath of a just God against homosexuals.”

We had to fight for the science and do the hard work of caring for the sick and dying while at the same time fighting the ignorance and bigotry of Christians and delusional religious fanatics like Jerry Falwell. At times it just seemed overwhelming.

If AIDS is the wrath of God against homosexuals, why have 90% of its victims been heterosexuals, women and children?

The fact is that Jerry Falwell and his “moral majority” ultimately lost the battle to keep us in the dark about HIV/AIDS. If Falwell and his comrades had won, how many more millions, even billions of people would now be dead?

We would still know absolutely nothing about HIV, the virus that causes AIDS. We would not know how to prevent its spread or treat it, and we would be decades behind in the quest to put an end to it altogether.

For all his rhetoric about being “pro-life,” he did his part to assure the deaths of millions of babies and children born with HIV.

In the end, Falwell died–just like all the people and the children that he gleefully helped push into their graves. Such is life. We all die. What differentiates us is what we do with our lives. Jerry Falwell chose a self-serving, narcissistic fantasy view of reality that put a supenatural value on his own life in relation to the lives of others. He chose hatred over compassion and the desire to understand the many bright lives he worked so hard to snuff out.

For that, I am sad.

I am sad that a man who did so much evil can delude himself into thinking he is good. I am sad and angry that there are millions of people who share his ignorant view of reality, and gave him millions of dollars to assist him in his war against science, knowledge and the lives of so many, including innocent children.

After 9/11, Falwell blamed the attack on his political opponents rather than the real killers–militant religious fanatics–who like Falwell use religion to justify their crimes against others.

After the September 11, 2001 attacks, Falwell said on the 700 Club, “I really believe that the pagans, and the abortionists, and the feminists, and the gays and the lesbians who are actively trying to make that an alternative lifestyle, the ACLU, People For the American Way, all of them who have tried to secularize America. I point the finger in their face and say ‘you helped this happen.’” Fellow evangelist Pat Robertson concurred with his sentiment.

I am sad that such evil can be viewed by so many as good.

It’s ironic that Tammy Faye Messner is also dying, given that Falwell took over the PTL Club after it imploded in a sex and money scandal. Messner was never as self-righteous in her hatred as people like Falwell, however. See related post: Tammy Faye Bakker Messner Stops Cancer Treatments
