Philosophy Flashcards
A defect (mistake error) in an argument but the defect is anything other than merely having false premises.
Fallacy
Two Types of Fallacies
Formal and Informal Fallacies
A type of fallacy where the mistake is in the form or structure of an argument.
Formal Fallacies
A type of fallacy where the mistake is in the content of an argument
Informal Fallacies
Five types of Informal fallacies
Fallacies of Relevance, Weak Induction, Presumption, Ambiguity, Grammatical Analogy
The premises are not logically relevant to the conclusion
Fallacies of Relevance
Fallacy is committed whenever the person giving the argument in some way THREATENS the listener.
Appeal to Force (argumentum ad baculum)
WHAT TYPE OF FALLACY? I’m the best man for the job. Anyone who says otherwise is in for a world of hurt.
Appeal to Force
I guess you will be testifying that I am innocent tomorrow. After all, neither of us wants anything to happen to your children, do we?
Appeal to Force
Fallacy is committed whenever someone tries to support a conclusion by evoking pity.
Appeal to Pity (argumentum ad misericordiam)
“But, I really need to pass this class. I need this class in order to graduate this semester, and I can’t afford to pay for more classes in the future. I already work 60 hours a week and supporting four children all by myself, and I’m barely scraping as it is, you should give me a passing grade”
Appeal to Pity
Fallacy is committed whenever the cause of the listener’s acceptance is that they are made to feel like they are part of something.
Appeal to the People
This occurs whenever the speaker implies to the listener(s) that
they will be left out or left behind if they do not agree with the speaker.
Appeal to the People (Indirect; Bandwagon Argument)
“Really? You don’t own a car? But EVERYONE owns a car.”
Appeal to the People (Indirect; Bandwagon Argument)
This occurs whenever the speaker associates the conclusion they are putting forward with some desirable person or feature. This puts in the listener’s mind the idea that, if they believe the conclusion, they will be JUST LIKE this desirable person, or they will HAVE this desirable feature too!
Appeal to the People (Indirect; Appeal to Vanity)
“You should buy a Ferrari. That’s what Tom Cruise drives.”
Appeal to the People (Indirect; Appeal to Vanity)
This occurs whenever the speaker associates the conclusion with being in an elite class or a lucky member of a select few.
Appeal to the People (Indirect; Snoberry)
“You should accept the offer at the summer internship.
How many people actually get accepted into that program?
SO many apply, and only a few get in.
You’ve got a one in a million opportunity right in front of you—
I can’t believe you’re even considering turning it down.”
Appeal to the People (Indirect; Snoberry)
This fallacy is committed whenever, someone, rather than providing EVIDENCE for their view, merely resorts to attacking their listener instead.
Argument Against the Person (argumentum ad hominem)
This occurs when one person, rather than supplying REASONS for why their opponent is wrong, instead resorts to directly verbally abusing the other.
Argument Against the Person (Abusive)
PEGGY: “I think you should slow down a little bit.”
SUE: “Well, you’re an idiot.”
Argument Against the Person (Abusive)
This occurs whenever someone, rather than supplying REASONS for why someone is mistaken, instead merely tries to make that person seem like a hypocrite.
Argument Against the Person (“You Too”, tu quoque)
PEGGY: “You shouldn’t eat fast food. I hear it’s really bad for you and could lead to health complications.”
SUE: “Whatever! You eat fast food all the time!”
Argument Against the Person (“You Too”, tu quoque)
This fallacy is committed whenever someone misapplies a general rule to one of the cases that is an exception.
Accident
POLICE OFFICER: “Are you lost? Where’s your Mom and Dad? Talk to me.”
CHILD: “I can’t talk to strangers.”’
Accident
This fallacy is committed whenever someone, in order to attack an opponent, attacks some WEAKER, DISTORTED VERSION of their opponent’s argument, rather than the actual argument, the opponent is giving. This often involves twisting an opponent’s words to be saying something much more absurd or ridiculous than they are actually saying. This ridiculous claim is much easier to refute, and (once it is refuted), the speaker then concludes that they have refuted their opponent’s ACTUAL argument.
Straw Man
PEGGY: “I’m just saying that nuclear energy would provide a lot of energy in a clean
way, so we should at least consider it as an option.”
SUE: “Oh, so you’re in favor of nuclear war? Is that what you want? For all of the countries to be nuking each other until we’re all dead? How ridiculous!”
Straw Man
This fallacy is committed whenever someone takes certain premises which support ONE particular conclusion, and—rather than draw THAT conclusion—they instead draw a DIFFERENT (but somewhat related) conclusion instead; and it is one that the premises do NOT support. The fact that the mistaken conclusion is loosely related to the real conclusion that the premises ACTUALLY support often makes the mistake persuasive and difficult to detect.
Missing the Point
“Our daughter got all D’s this semester at D University. Every single professor there should be fired!”
Missing the Point
PEGGY: There is so much welfare corruption! They found out that some people
are using welfare checks for drugs and gambling.
SUE: I know! We should just get rid of the welfare program!
Missing the Point
This fallacy is committed whenever someone responds to their opponent by changing the subject to something completely different. Sometimes, the different topic can be loosely related to the actual topic that was being debated. When this happens, red herrings can be misleading in a very subtle way that is difficult to detect.
Red Herring
PEGGY: “The scientific community is in unanimous agreement. We are altering the climate, and if we continue on our present course, the results will be disastrous. Climate change is a real problem in this world.”
SUE: “You know what’s a problem in this world? People just believing everything they hear. People will believe just about anything, as long as it’s said on television.”
Red Herring
