Q

What is to evaluate an argument?

A

To evaluate an argument is to critically examine the relation between its evidence and its claim, assessing whether the principles of good reasoning are violated.

For an argument to be good in the fullest sense it must accord with all of the principles of good reasoning, not just to one.

A

Occurs when one assumes that because every part of a whole (or every member of a class) has such-and-such attribute, the whole itself (or the class itself) must have that attribute too

20
Q

Explain the Fallacy of Division

A

When one assumes that what is true of the whole must be true of the parts.

A

Does the argument commit a non sequitur?

  • Occurs when the evidence is not logically relevant to the truth of a claim.
23
Q

  3. Appeal to ignorance (Argumentum ad ignorantiam)
  4. Appeal to inappropriate authority
  5. Genetic fallacy
  6. Straw man
  7. Slippery slope
  8. Irrelevant conclusion (ignoratio elenchi)
24
Q

When a person attacks another in order to show that what the other person said is wrong, false, or should not be taken seriously.

  • Whipping the emotions of the audience
  • Truth is not determined by head count
26
Q

Explain the Appeal to Ignorance Fallacy (argumentum ad ignorantiam)

A

When one argues either that a claim is true because it has not been proved to be false, or that a claim is false because it has not been proven to be true.

27
Q

Explain the Fallacy of Appeal to Inappropriate Authority

A

When one appeals to the testimony of an expert in matter outside the domain of that authority’s special field

  • This is different than just reporting what someone says
