"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 cartoon, Ruth!

Rereading the intro here... one of my favorite examples of invalid logic producing a true conclusion is "simplifying" the fraction 16/64 by canceling sixes: 16/64 = 1/4.

NO! This way, head!

And while I'm on your case, the sign you put up is so biased that I'm betting you won't tell us what's eating you.

I almost always head out of the country for my news, Sk8ey.

Thanks for the Ruby Bridges video! I remembered her from a newspaper clipping seen when very young, and I always wanted to know how she went on from that first day at school.

We haven't had true freedom of the press in 200 years. 

The last gasp for me was when the Los Angeles Times was sold to the Chicago Tribune conglomerate about 20 years ago.  They fired the best political columnists, and kept on cutting staff, and the number and size of the pages until the thing looks like a tabloid.  I want to cancel our subscription, but it's sort of an 80+ year tradition in our family.  My sister reads it. I don't.  So I told her to pay for it.

Just reading the newspapers will inform anyone when there's controversial legislation being brought out. If it's concerning immigration it'll be a daily dose of ''Somali women housed in six bedroomed house all at the taxpayers cost'' or something along those lines. Similarly for welfare ''Benefit scrounger's costing the country billions, say's report''. These 'revelations' curiously stop when the legislation has been passed.

How can the west so proudly proclaim ''freedom of the press'' when the press is so unashamedly used for government propaganda.

It seems news censorship and manipulation is a disgrace when conducted by authoritarian states, but quite acceptable under the flag of free enterprise.

I remember British rock bands in the sixties coming back aghast at what they'd witnessed in the American south.

"The first purpose of government," a graduate student in political science told me decades ago, "is to make large numbers of people governable."

And as Joan says, religion was and is a device to control people.

Keeping church and state separate is my first purpose.
