"Extraordinary claims require extraordinary evidence." -- Carl Sagan

"What can be asserted without evidence can also be dismissed without evidence." -- Christopher Hitchens

What is a logical fallacy? All arguments have the same basic structure: A therefore B. They begin with one or more premises (A), which is a fact or assumption upon which the argument is based. They then apply a logical principle (therefore) to arrive at a conclusion (B). An example of a logical principle is that of equivalence. For example, if you begin with the premises that A=B and B=C, you can apply the logical principle of equivalence to conclude that A=C. A logical fallacy is a false or incorrect logical principle. An argument that is based upon a logical fallacy is therefore not valid. It is important to note that if the logic of an argument is valid then the conclusion must also be valid, which means that if the premises are all true then the conclusion must also be true. Valid logic applied to one or more false premises, however, leads to an invalid argument. Also, if an argument is not valid the conclusion may, by chance, still be true. For a more thorough discussion of logical fallacies and how to structure a logical argument, see the New England Skeptical Society's article, How To Argue.

"No skeptic, to my knowledge, ever made a major scientific discovery or advanced the welfare of others."

-- Deepak Chopra (yes, he actually said that)

"The most exciting phrase to hear in science, the one that heralds the most discoveries, is not "Eureka!" (I found it!) but That's funny..." -Isaac Asimov

The scientific world view is full of awe and wonder. Understanding how truly awesome the universe is – in its elegant complexity, its staggering beauty, and the many intricate systems of which it is comprised – gives a profound feeling of connectedness and sparks the imagination. And it has the advantage of being real. -Steven Novella

The glory which is built upon a lie soon becomes a most unpleasant incumbrance. How easy it is to make people believe a lie, and how hard it is to undo that work again.
— Mark Twain

@ Christopher
"comment number 56 by Doctorlogic"

Dr. Logic does not give any sources, and starts out with the statement, "from what I hear". So this judgement is being based on hearesay?

He's also using loaded language ("heavies" and "sinister"). Perhaps he's justified in using this language, but I'd certainly need to more than the word of somebody's blog comment.

Note: He "assumes" Koger had a jury trial - so it's not like he's even following the case very closely.

Oh snap, that's right! And she's all about research too! AND ALL BRAIN DAMAGE IS AUTISM! My mind! She is blown!

Science did that yesterday, didn't it? Yes, yes they did.

Have a good time Christopher, say hello to the wife.
Comment by Christopher on September 8, 2010 at 8:16am
Which is one of the reasons I love this group. I'd forgotten to add, I'm going out of town for about a week. My wife has yet to go to Gruene Hall or the Alamo, and those are absolute requirements for citizenship here, so away we go.

I usually read Ed Brayton's Dispatches From The Culture Wars blog as well, just because it touches on politics and the law much more frequently, but Ed has a huge achilis heal when it comes to law enforcement related issues, frequently goes off half cocked on issues he just doesn't know anything about, and I've bitch slapped him about three or four times. By "bitch slapped" I mean, I compared his post to those by people who push intelligent design and make themselves look like idiots because they just don't know anywhere near enough about evolution to construct an informed opinion on it. It hasn't swayed Ed, though. He just, evidently, has some irrational blind spot in that area. So I'm used to it from Ed, but when PZ did it, my jaw hit the floor. WTF?? Made me wonder if PZ's not all the way back to full function, from the meds and the recent surgery. You dont really need to research anything that much before posting it here, because if the issue needs slapping around, these fuckers round here will bitch slap it in a heartbeat.

You guys are great

I had not heard about the Gregory Koger incident until I saw PZ's post yesterday. I was hoping that someone would have more information, since I had not had the time to do any research.

Thanks for clarifying. The way PZ makes it sound, is not at all like the reality.

Thank you for pointing out comment #56, Christopher.

I really should have done my homework before I posted it. It was a spur of the moment thing. I'm sorry for the lack of critical thinking.
The logical fallacy was argument from authority and I should have known better.

The information is appreciated.

It had to happen eventually, I suppose, because I've been reading PZ's blog daily for about a year or two now, and I kept wondering when he would post something I disagreed with. Well, he finally did. I had intended to reply on his blog, but after scolling down the comments to comment number 56 by Doctorlogic, I found someone had posted pretty much exactly what I would have posted, so I didn't bother. I really couldn't beleive that screed from Sunsara Taylor which PZ quoted in his post. The first couple of paragraphs are fine, but then she descends into nutjob, idealist rantings like a fundamentalist quoting the Left Wing Fringe Bible. She seems about as rational as Donald Wildmon.

Daniel, that is a good idea. According to "like preventing like" principle it would prevent the coming of further "god's children".

Just have him made into homeopathic birth control remedies.
