"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

No poop? But you can roll in it right? My dogs seem to think it's O.K.

Yeah, if you stare at the sun long enough you'll probably hallucinate before ruining your eyes...wow.

Those silly religious folk are at it again staring at the sun long enough to have to go to hospital with retina burns. (solar retinopathy)

"We clearly need a set of PSAs targeted specifically at religious audiences. Don't jump off of tall building because you can't fly, don't eat poop because it tastes yucky and is full of bacteria, don't poke yourself in the eye with a fork when you eat, that sort of thing. They clearly need help." -PZ Myers

Chopra: This is the "collusion" get out of jail free card. Nothing is more terrifying to cranks than independent people arriving at the conclusion they are cranks independently. Therefore, there has to be collusion. Cheap, brainless and it works.

Hey, maybe he's right about wrong being wrong! He might even be right about what's left. Depends on what is is (oh wait, that's someone else).

Skepticcat, I think it depends on the nature of the nonsense. Simple incongruity makes you stop and think, "What's wrong with this picture?" That gets the ol' Sesame Street juices flowing. Horseshit presented with plenty of PR can sucker you in, especially if it directs your attention away from any incongruities.
