"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

Request For A Discussion Thread --
Since I know we all have so much time, it would nice if someone (Felch, Jacqueline, ??) could do a thread with information about how to document the research we may do. Although we know that a site, section, page, document, description, link, etc. would never just disappear or change on the internet, planning for a worst case seems prudent. I'm thinking printouts, screen caps, torrents, etc. What are the pros and cons of each? Not just for possible legal issues ('cause we know that would never happen), but for armoring our conclusions. Along the legal lines, I think the Electronic Frontier Foundation (eff.org) has a guide for bloggers that may also be appropriate. I'll see if I can find it again and forward the information to Sacha.

@Felch. Would you have any idea why I'm not receiving Group notifications of new Discussions? My settings are set correctly. I haven't been receiving them for any groups just Discussions from the main page.

Should I be reporting this or this a new configuration for A/N?

I feel left out. My favorite cartoon was Rocky & Bullwinkle. But I'll get over it, since there is a preponderance of scoobyphilia here and we all have to compromise for the greater good.
