Sean McDowell debates James Corbett on whether morality is grounded by atheism

Brian Auten posted the audio a few milliseconds after the debate concluded!

Here is the MP3 file.

Sean’s case is similar to the one I make, but he only has 3 minimal requirements for morality.

First, he explains the difference between objective and subjective truth claims, and points out that statements of a moral nature are meaningless unless morality is objective. Then he states 3 things that are needed in order to ground objective morality.

  1. an objective moral standard
  2. free will
  3. objective moral value of humans

The question of the foundations of morality is without a doubt the easiest issue for beginning apologists to discuss with their neighbor. If you’re new, then you need to at least listen to his opening speech. He’s an excellent speaker, and his rebuttals are very, very smooth. The citations of atheist philosophers like Walter Sinnott-Armstrong, e.g. – to show that “religious” wars had nothing to do with religion, really hurt his opponent. He seems to cite prominent atheists like Thomas Nagel, Richard Taylor, Michael Shermer, etc., constantly in order to get support for his assertions. That took preparation. I can’t believe that McDowell is this calm in a debate situation.

When I listen to Frank Turek, he seems to struggle in his rebuttals. McDowell sounds like he foreknew exactly what his opponent would say and pre-wrote responses. He even had powerpoint slides made in advance for his rebuttals! I am not making this up – Corbett even remarked on it.

For those of you who want to understand how these things work, listen to the debate. There is a period of cross-examination if you like that sort of thing. I do!

Doug Axe explains the chances of getting a functional protein by chance

I’ve talked about Doug Axe before when I described how to calculate the odds of getting functional proteins by chance.

Let’s calculate the odds of building a protein composed of a functional chain of 100 amino acids, by chance. (Think of a meaningful English sentence built with 100 scrabble letters, held together with glue)

Sub-problems:

  • BONDING: You need 99 peptide bonds between the 100 amino acids. The odds of getting a peptide bond is 50%. The probability of building a chain of one hundred amino acids in which all linkages involve peptide bonds is roughly (1/2)^99 or 1 chance in 10^30.
  • CHIRALITY: You need 100 left-handed amino acids. The odds of getting a left-handed amino acid is 50%. The probability of attaining at random only L–amino acids in a hypothetical peptide chain one hundred amino acids long is (1/2)^100 or again roughly 1 chance in 10^30.
  • SEQUENCE: You need to choose the correct amino acid for each of the 100 links. The odds of getting the right one are 1 in 20. Even if you allow for some variation, the odds of getting a functional sequence is (1/20)^100 or 1 in 10^65.

The final probability of getting a functional protein composed of 100 amino acids is 1 in 10^125. Even if you fill the universe with pre-biotic soup, and react amino acids at Planck time (very fast!) for 14 billion years, you are probably not going to get even 1 such protein. And you need at least 100 of them for minimal life functions, plus DNA and RNA.

Research performed by Doug Axe at Cambridge University, and published in the peer-reviewed Journal of Molecular Biology, has shown that the number of functional amino acid sequences is tiny:

Doug Axe’s research likewise studies genes that it turns out show great evidence of design. Axe studied the sensitivities of protein function to mutations. In these “mutational sensitivity” tests, Dr. Axe mutated certain amino acids in various proteins, or studied the differences between similar proteins, to see how mutations or changes affected their ability to function properly. He found that protein function was highly sensitive to mutation, and that proteins are not very tolerant to changes in their amino acid sequences. In other words, when you mutate, tweak, or change these proteins slightly, they stopped working. In one of his papers, he thus concludes that “functional folds require highly extraordinary sequences,” and that functional protein folds “may be as low as 1 in 10^77.”

The problem of forming DNA by sequencing nucleotides faces similar difficulties. And remember, mutation and selection cannot explain the origin of the first sequence, because mutation and selection require replication, which does not exist until that first living cell is already in place.

But you can’t show that to your friends, you need to send them a video. And I have a video!

A video of Doug Axe explaining the calculation

Here’s a clip from Illustra Media’s new ID DVD “Darwin’s Dilemma”, which features Doug Axe and Stephen Meyer (both with Ph.Ds from Cambridge University).

I hope you all read Brian Auten’s review of Darwin’s Dilemma! It was awesome.

Illustra also made two other great DVDs on intelligent design. The first two DVDs “Unlocking the Mystery of Life” and “The Privileged Planet” are must-buys, but you can watch them on youtube if you want, for free.

Here are the 2 playlists:

I also recommend Coldwater Media’s “Icons of Evolution”. All three of these are on sale from Amazon.com.

Harvard-educated evolutionist arrested for multiple-victim school shooting

The leftist NYT reports:

The Huntsville Times identified Dr. Bishop as a Harvard-educated neuroscientist.

[…]Dr. Bishop had told acquaintances recently that she was worried about getting tenure, said a business associate who met her at a business technology open house at the end of January and asked not to be named because of the close-knit nature of the science community in Huntsville.

“She began to talk about her problems getting tenure in a very forceful and animated way, saying it was unfair,” the associate said, referring to a conversation in which she blamed specific colleagues for her problems.

And a student review from her page at RateMyProfessors.com:

This class was great. Bishop makes the class interesting by talking about her research and her friends research. That speaker she had for class was hard to understand but smart. She expects a lot and you need to come to every class and study. She is hot but she tries to hide it. And she is a socialist but she only talks about it after class.

Shot her brother dead:

A Massachusetts police chief is now saying that UAH shooting suspect Amy Bishop shot and killed her brother during an argument, and the case may have been mishandled by the police department more than two decades ago when the fatal shooting occurred.

According to this web page, she likes to advocate evolution to members of the clergy.

UPDATE: From the Boston Herald.

Excerpt:

Reyes confirmed he is working with the FBI to learn more about why Bishop was a suspect in the attempted bombing of Dr. Paul Rosenberg, who received a double-pipe bomb in the mail on Dec. 19, 1993. He ran from his Newton home with his wife, escaping without injury. The bomb never exploded.

[…]A family source said Bishop… was a far-left political extremist who was “obsessed” with President Obama to the point of being off-putting.

Very strange. Like a female version of Bill Ayers.

UPDATE 2: From the Boston Globe.

Excerpt:

In March, 2002, Bishop walked into an International House of Pancakes in Peabody with her family, asked for a booster seat for one of her children, and learned the last seat had gone to another mother.

Bishop, according to a police report, strode over to the other woman, demanded the seat and launched into a profanity-laced rant.

When the woman would not give the seat up, Bishop punched her in the head, all the while yelling “I am Dr. Amy Bishop.”

Sounds like a pretty typical Obama voter to me!
