"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

->felch: The best way to handle "specific nonsense angles" would be to deconstruct specific documents or posts to show the tools in use. (I think this is called 'fisking' now on the interwebs.) Are there some major documents (in the sense of important or canonical, not length) that we could do this on? Or maybe we post/link something and ask for a detailed working out of what's wrong?

A useful video to learn from and to pass along to others that could be helped by it is the RDF TV Baloney Detection Kit by Michael Shermer that's been here for awhile.

Oh and Scooby Doo thanks you too

Hello all! Specific links is what I had in mind. Let's dissect each specific nonsense. These links you have provided are a great addition. I'll add some of them to the top of the group. Thanks for joining me.

Folks - intead of just throwing around links, how about creating specific posts about specific nonsense angles and colating the info coherently. Incoherence is the weapon of the spook.

See also the Critical Thinking mini-lessons from the Skeptic's Dictionary

For homework lessons, test out your knowlege on the Hundreds of Proofs of God's Existence page.

The Bad Moves page over at Butterflies and Wheels has some interesting articles by philosopher Julian Baggini.

Although not exactly fallacies, cognitive biases sometimes explain why people argue in fallacious ways. Check out the big list over at the Wiki.
