Syllogism
simplest possible mediate inference; consists of 3 terms (minor, major, middle); consists of 2 premises; requires proper arrangement to be valid
Middle Term
the term that is in both premises but not in the conclusion
Minor Term
subject of the conclusion
Major Term
predicate of the conclusion
Minor Premise
the premise with the minor term
Major Premise
premise with the major term
Rule 1
can only have 3 terms
Rule 2
can only have 3 propositions/statements
Rule 3
the middle term must be distributed at least once
Rule 4
an undistributed term in a premise can NOT become distributed in the conclusion
Rule 5
cannot have two negative premises
Rule 6
if there is one negative premise the conlusion must be negative
If the subject is universal…
the subject is distributed
If the subject is particular…
the subject is undistributed
If the predicate is affirmative…
the predicate is undistributed
If the predicate is negative…
the predicate is distributed
Strong Argument
is one in which it is probable (but not necessary)
that, if the premises are true, then the conclusion is true.
Weak Argument
is one in which it is not probable that, if the premises
are true, then the conclusion is true.
Cogent Argument
is a strong argument in which all of the premises
are true(kinda like being sound)
Uncogent Argument
is one that is either weak or strong with at
least one false premise.
Deductive Logic
is the part of logic that is concerned with the study of methods
of evaluating arguments for validity and invalidity.
Inductive Logic
is the part of logic that is concerned with the study of methods
of evaluating arguments for strength and weakness.
Argument Against the Person/Ad Homien
Premises: Instead of providing a rational critique of a statement (or argument),
attack the person who advances it.
Conclusion: The statement is false or dubious. (Or the argument is unsound
or uncogent.)
Straw Man Fallacy
Premises: A misrepresentation of the view is false.
Conclusion: The view itself is false.
