"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

I was joking sacha, but I do dislike the cartoon. Another good URL: The Skeptic's Dictionary.

Scooby Doo was the first Skeptic show. That's the reason he is our mascot

I put off joining, because I'm not a fan of animated talking dogs, repressed woman-loving-women, and the obligatory heteronormatives. I'll just avert my eyes since the icon seems so popular.

Let me re-phrase

I think that Skepticcat, Daniel, Felch, Dallas, and Richard Healy (among others) have been able to capture the humour I'm looking for. Skepticcat is right, I do not want more preaching to the choir here, it is too difficult to change the subject once it is about religion. I do not want to alienate anyone either, I just want to make the mission of the group a bit more clear.

I like the idea of combating sloppy thinking, regardless of topic. I don't think we'll have to spend as much time on theist arguments anyway, since theists aren't supposed to be on the site bothering us with illogic. But that doesn't stop anti-vaxxers, troofers, birfers, paranormalists, etc, etc.
Comment by Richard Healy on November 24, 2009 at 9:55pm
I'm actually rather partial to nonsense.*

But I shall oppose lies and distortion and misappropriation of science and the-plain stupid knuckle-draggers of creationism and pseudoscience as long as there is a breath in my body, if that counts.

*The time has come," the Walrus said,
"To talk of many things:
Of shoes--and ships--and sealing-wax--
Of cabbages--and kings--
And why the sea is boiling hot--
And whether pigs have wings."

Can you work out how the new Telepath application reads your mind? http://bit.ly/7bPrHS

Everything can be discussed (or vented about) in many other places on this site.

Exactly what problem are you trying to solve with your guidelines?

IMO as long as the Discussions are related to logical fallacies and erroneous arguments that are used to support idiotic claims they are consistent with the purpose of this group.

Am I wrong?

I think Dallas has the idea. This group was created to have a laugh at all of the nonsense out there, and perhaps hone our skills in counting and identifying the logical fallacies. Guidelines shall be posted soon. : )

cheers
