New Atheism: New Irrationality

British sceptic Daniel Came of The Guardian takes New Atheist Richard Dawkins to task for refusing to debate with " intellectually rigorous theist" Daniel Craig.
Given that there isn't much in the way of serious argumentation in the New Atheists' dialectical arsenal, it should perhaps come as no surprise that Dawkins and Grayling aren't exactly queuing up to enter a public forum with an intellectually rigorous theist like Craig to have their views dissected and the inadequacy of their arguments exposed.

Ironically, there is nothing substantively new about the New Atheists either. Despite its self-congratulatory tone, The God Delusion contains no original arguments for atheism. ...

As a sceptic, I tend to agree with Dawkins's conclusion regarding the falsehood of theism, but the tactics deployed by him and the other New Atheists, it seems to me, are fundamentally ignoble and potentially harmful to public intellectual life. For there is something cynical, ominously patronising, and anti-intellectualist in their modus operandi, with its implicit assumption that hurling insults is an effective way to influence people's beliefs about religion. The presumption is that their largely non-academic readership doesn't care about, or is incapable of, thinking things through; that passion prevails over reason. On the contrary, people's attitudes towards religious belief can and should be shaped by reason, not bile and invective. By ignoring this, the New Atheists seek to replace one form of irrationality with another.
That's because New Atheists are ideologists, not honest inquirers.

Update: Dennis Prager shows how university professors are more irrational than evangelicals.

Pale Blue Dot


What's the most epic photo ever taken? - Quora

The answer is a photo of Earth taken from the edge of the solar system.
Pale Blue Dot is a photograph of planet Earth taken from a record distance of 3.7 billion miles, at the edge of our solar system. It was shot and transmitted by the Voyager 1 spacecraft almost 13 years after its launch.

Jeopardy's Watson computer: Just a high-speed moron

Here is the Youtube of IBM's computer, Watson, beating its human challengers like a mongrel dog on Jeopardy last night. Look carefully at the clues? Notice anything?



Almost none of the answers on the game board required any kind of abstract reasoning to answer. In fact, you could put a human with practically no knowledge of the subjects on the board in front of a computer connected to Google and that person could simply type in the nouns of the clues and get the same answers.

Example - the first question of the game:


And the Google:


Strip out Watson's blinding speed, and it is no smarter than human beings at all. Watson, for all its engineering impressiveness, simply did only what computers have always done: collate at blinding speed (and compute mathematical probabilities to choose an answer). It does not matter that Watson was not connected to the Internet since its mass-memory unit holds 16 Terabytes of data, processed by a 2,880 processor core. As my own computer professor said (many years ago!), "A computer is just a high-speed moron." There is nothing about Watson that I have read so far that obviates that observation.

I think its programmers must have realized this since they artificially crippled Watson by design. Note that Watson was programmed not to buzz in unless it computed an answer of at least 50 percent "confidence" of being right. This was an entirely artificial barrier. Why not 75 percent? Or 25 percent? Or any level at all? Watson is so blindingly fast that it could have buzzed in for every question before either champion (making their presence merely ceremonial, which it almost was anyway). Then Watson simply could have given its top answer, regardless of confidence level, and the computer still would have got 90% of the questions right.

In other words, if the game had allowed Watson to give uncrippled answers, it would have always answered first and would have won even more decisively. But then, with access to the same amounts of data resources through Google, I could beat the two champions if the game always allowed me to answer first. In fact, I'd win under the same confidence crippling as long as I could answer first - because clearly Watson will always be able to buzz in faster than a person.

So what does Watson really prove? From a technical, engineering and programming perspective, it's an amazing achievement with enormous potential for a wide range of applications ranging across broad multi-disciplinary subjects and problems. As for the Jeopardy game, there's less than meets the eye. Count it as a proof-of-concept exercise. What it did not do was reason abstractly. It just collated amazing amounts of information very rapidly. But we already knew that computers are faster than we are for specified tasks. That's why we build them to begin with.

Sorry, Prof. Reynolds, the Singularity has not arrived.

Update: Good discussion on this at The Speculist, including this nugget:
@stephentgo: Repercussions of IBM's Watson unknown, but any job that involves answering questions by phone will soon be at risk. http://bit.ly/hp91hW

Richard Dawkins - Protestant Atheist

The problem with Richard Dawkins' atheism is not his atheism, per se, but that his atheism is so Protestant.
My problem with Richard Dawkins is not that he is an atheist. I admire that. It's that he's a Protestant atheist. Religion, many think, has been slain by the experimental method of science. Beginning with Galileo's experiments on free fall, science has succeeded because it is value-free, objective and proves its points not by nebulous belief but by rigorous logic and verified proof. This is a complete misunderstanding.
And as it turns out, scientists are not nearly as atheistic as some folks such as Dawkins make them out to be. More than 70 percent of scientists describe themselves as "religious in the traditional sense" or "spiritual."
