Fallacy of Equivocation

 

Bank Argument

1)             I went to the bank today (financial institution).

2)             Anyone who goes to the bank has soggy shoes (river bank)

3)             Therefore, I have soggy shoes.

 

Abortion Argument

1)             It is wrong to kill innocent human beings (moral entity)

2)             Fetuses are innocent human beings (biological entity)

3)             Therefore, it is wrong to kill fetuses

 

These arguments aren’t valid, the premises don’t provide good grounds for the conclusion, as the terms bank and human beings are used differently in the two premises. This argument commits the fallacy of equivocation.

 

Vagueness

·      Things are being worked out so that something can be brought into effect at the appropriate moment.

·      Mistakes were made.

 


From Howard Dean’s Web Page

 

Under the unfair and misguided policies of the Bush Administration, our country has lost nearly 3 million jobs — that means more moms are struggling to earn enough to care for their children, more dads are worrying about being able to provide for their families, young people are still waiting to start jobs out of college, and older workers who were planning to retire must keep working— often at jobs that waste their talents and experience.

 

Euphemism

Collateral damage (Civilian Deaths)

Vertically Challenged (Short People)

 

 

The reason this argument is flawed is because of the conclusion

 

The premises don’t provide any grounds for the conclusion because you have to believe the premises before you can believe the conclusion.
