"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

How wonderful that Lincoln was gay. He is such an important part of history in the US, and I'm quite sure that would really piss off those who are so "Pro America" and anti-gay.

quote of the day:

"...If I could change just one thing, it would be to dissociate the idea of faith from virtue—now and for good—and to expose it for what it is: a servile weakness, a refuge in cowardice, and a willingness to follow, with credulity, people who are in the highest degree unscrupulous.”

Sacha,
thank you for quoting a famous gay president.

Perhaps I haven't been personally embroiled in enough contretemps, but I don't seem to have too much trouble just ignoring the clowns and the low quantity of moderation. Like I keep saying, A|N beats the hell out of a lot of places I've been on the internet.

If somebody pisses me off on A|N, I let them know it isn't appreciated. If they keep it up, I Report An Issue. Maybe two or three times. After that, I just kinda let it go. There are worse injustices in the world.

If the mods came down on my ass unfairly, I'd defend myself, but even then, this little Speakers' Corner is just one possible outlet for me. I do value it, but I also value my time and my blood pressure. I'm not inclined to fixate overmuch on the lesser slings and arrows.

I'm not sure what my plans are yet, but I no longer enjoy my time here at A|N, but I'll never just disappear from our little group here.

I'll keep everyone posted, and if we decide to have a similar group, or just continue with No Nonsense elsewhere, you will be invited and more than welcome.

I have written about some of my feelings in my comment to Felch's discussion here.

There is much more that I am unhappy about than what I have spoken of publicly, and it has been building for quite a while.

This group and the core members are the main reasons I have have not left, and I don't plan to give up what we have here. As I said, I'm not sure what my plans are, I just know that I am frustrated and annoyed with the way A|N is being run, and it is getting worse by the day.

I see no reason to continue when it is stressful and frustrating. Life itself has enough of that, and I try my best to stay away from drama in every form.

I am going to attempt to come here to NN and ignore the side bar for a while and see how that plays out until I decide what I want to do.

Re: Jason's comment below,
Can the ironic perceive the literal?

Re: Phil's Woody Allen comment. My favorite Woody Allen quote: "How can I believe in God when just last week I got my tongue caught in the roller of an electric typewriter?"

To most of you, the device known as "electric typewriter" was sort of like a computer keyboard attached to a printer, but without the computer in between. You had to place a sheet of paper into it. It didn't remember what you typed, but printed onto paper each letter instantly as you typed it. The paper was held in place by a device called a "roller" which is what Mr. Allen got his tongue stuck in. There was an even earlier device called simply "typewriter" that was actually quite energy efficient, didn't even have a plug. It was powered entirely by its user's actions.

Ah. That explains why Felch was AWOL. He was writing a book about the madness thread. Gonna take me a bit to get thru it.
