"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

Great illustration over at Friendly Atheist:

'evolution' on three jigsaw puzzle pieces fitting together perfectly, a DNA sequence in the background, contrasted with 'Creationism' on three mismatched puzzle pieces, an aged-looking creation story from Genesis in the background

... Anyone having sex in front of the altar must be asking god to approve ...

I remember something from the Wiccan "Charge of the Goddess" that "all acts of love and pleasure are my rituals."

They got that so much more right than the Abrahamic religions! (And people who look to the Jewish or Christian Bible for inspiration or authority often forget that "be fruitful and multiply" continues with "fill the earth and subdue it." At 7.4 billion people and counting, and all the pressure that creates on resources, food, water, energy and thus climate... migration... wars... we've certainly fulfilled that command and then some!)

Comment by Michael Penn on November 15, 2016 at 6:59am

Anyone having sex in front of the alter must be asking god to approve of their act. He did that already with the command of be a fruitfly and multiply. A little bit of that and one of you will divide.

o thát statue..

“Give me your tired, your poor,
Your huddled masses yearning to breathe free,
The wretched refuse of your teeming shore.
Send these, the homeless, tempest-tossed to me,
I lift my lamp beside the golden door!”

I often think of it when Americans are so terrified of refugees..

Comment by tom sarbeck on November 15, 2016 at 12:59am

"Come to me all who are weary and burdened..."

Aren't those much like the words on that statue in NY harbor?

Don't tell the GOP's ISIS-like xians; they'll dynamite the statue.

On not locking the door of a chapel frequented by college students:

A male student a decade older than I fretted that couples might enter and copulate in front of the altar. He seemed serious.

Comment by Joan Denoo on November 15, 2016 at 12:14am

Or the church that spends vast amounts of money for chalices and linens and complain that if they leave the door unlocked someone will steal valuable items. 

Tsk! Tsk! Tsk!

Comment by Plinius on November 15, 2016 at 12:08am

Reminds me of that firmly padlocked churchdoor, over it the words "Come to me all who are weary and burdened..."

Comment by Grinning Cat on November 14, 2016 at 3:43pm

Sort of like the doorbell, "Ring bell for psychic"... or the "Psychic ATM" that never simply spit out the amount of cash I wanted to withdraw when I just walked by. (Why should it even need a keypad or a card slot??)

More seriously, wasn't there at least one psychic who was brought up on (totally unforeseen) fraud charges?
