Common Logical Fallacies
Traps that are used in argumentation. May appear correct at first, but are usually very flawed
Some History and Background
What is an "argument"?
Monty Python's "Argument Sketch"
More Common Logical Fallacies
Even More Fallacies
Dear God... Still More?
"What is an argument?"
"Common Logical Fallacies"
Argumentation: Pt. 1
"[A] connected series of statements intended to establish a proposition"
is to offer good
to support a
a back-and-forth "No"-"Yes"-"No"
The actual symbol for "philosophy,"
I kid you not.

1) Emotional Fallacy:
2) Bandwagon Appeal:
3) Ad Hominem (Attacking the Person):
Preys upon people's emotions to win, rather than logic.
Uses words and phrases that conjure up strong images that most likely get people riled up.

Arguer assumes what they are claiming is already true without having proven anything yet
Arguer goes around in a circle, never adding anything new to support their conclusion
"Begging the Question" is a type of Circular Argument
When you limit the choices your opponent can claim
Claim stating that "A" is the reason why "B" when it may not be entirely true
Step 1: Listen to Opponent's claim.
Step 2: Distort, exaggerate, or misrepresent the claim.
Step 3: Attack newly distorted claim.
Step 4: Profit!
What happens when the conclusion has no connection to the premises
"Non sequitur": Latin for "does not follow"
1) Think about the last "argument" you might have had. What was the subject? What was trying to be proven or disproved? (Feel free to change names, places, etc. to whatever is comfortable for you.
2) Log onto the internet and find an example of one of the fallacies we discussed. What fallacy is it? Why is it wrong? What would you do to fix the argument?
