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.

"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've got no problem with everyone saying "merry christmas" on christmas day. however, they've turned it into an entire holiday season where it lasts a month or more. in those situations it should be perfectly acceptable to say "happy holidays" or call it a…
I posted the bulk of this on another thread, but wanted to add some context separately.
I finally confronted my faith and embraced the fact of my atheism late last August, 2012. Days after I revealed my "epiphany" to a few friends who knew me from another message board, my sister died from Lou Gehrig's Disease (which pissed her off because she hated catching a disease from someone she never f---ed).
THAT was my sister, understand? She was a beautiful, life-loving, potty-mouthed…
OK. I am venting. My mother died two weeks ago. She was a “god fearing christian.” Before her death she refused all medical treatment. She wanted to be left alone. She even refused to speak with my brother who is a methodist minister. He is a pip, let me tell you! I suspect she did not believe, but a woman born in her time could not and did not state her actual beliefs. This is the opening salvo to all christians; FUCK YOU! I had so many people come and tell…
This probably should not have shocked me as much as it did (especially since I am in Texas). I actually thought my coworkers were playing a joke on me because they know I am an atheist. Sadly, this was no joke. This actually happened.
I work in a psychiatric hospital. The doctors who admit patients are general MDs. (Psychiatrists see patients after admission) Yesterday evening we received several calls from irate parents. A new doctor who was doing admissions yesterday actually…
