"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 feel an urge to explain that flying hippo picture.

Proving that QotD is WAY too deep for me.

Comment by Glenn Sogge on September 15, 2010 at 9:53am
QotD: "Few people would deny the need to explain unusual phenomena (e.g., flying hippos), but fewer would demand an explanation for what is common and ordinary (e.g., time), and it is precisely here where the task of the philosopher begins, first in making us de-familiarize ourselves with, and question the nature of, the ordinary, and then in attempting to explain it." ~ Article on The Principal of Sufficient Reason in the Stanford Encyclopedia of Philosophy.

quote of the day:

"If I had a world of my own, everything would be nonsense. Nothing would be what it is, because everything would be what it isn't. And contrary wise, what is, it wouldn't be. And what it wouldn't be, it would. You see?"

(From Alice In Wonderland)

Many in China distrust vaccines - no Zhenny McCarthy yet tho. China mass measles vaccination plan sparks outcry.

A few thoughts-
distrust of vaccines is not just an effete syndrome of silly coddled Westerners. some lessons for us.
Underlying causes of that distrust are an issue - see article.
China is ascendant - will replace US as dominant world power in this century (my opinion, but I think others feel that way). It's an aggressive nation and there is reason for concern. I always feel some schadenfreude when I see articles like this. Bad me.

Interesting. I've always respected CSM even tho the religion itself is so much hooey, and dangerous hooey at that - like many other religions. I just subscribed on my e-reader, based on IJM's recommendation - it's a 14-day free trial, so I like that. I don't know if reading liberal BS is an antidote to conservative BS. Although Dame Judy Dench did state in the Chronicles of Riddick that sometimes you have to fight evil with another kind of evil, or something like that. And I'll believe anything she says in a sci fi movie especially when referring to Vin Diesel.
