Q. What are the three important valid argument forms?
Valid Argument Forms
- Modus Ponens. If P then Q. P. ∴ Q.
- Modus Tollens. If P then Q. not Q. ∴ not P.
- Disjunctive Syllogism. P or Q. not P. ∴ Q.
- Hypothetical Syllogism. If P then Q. If Q then R. ∴
- Barbara Syllogism. All A’s are B’s. All B’s are C’s. ∴
- Reductio ad Absurdum. P. ∴
- Replacement. a is an F. a = b. ∴
- Proof by Cases. P or Q. If P then R. If Q then R.
Q. What is a valid argument in logic?
Valid: an argument is valid if and only if it is necessary that if all of the premises are true, then the conclusion is true; if all the premises are true, then the conclusion must be true; it is impossible that all the premises are true and the conclusion is false.
Q. What is form of an argument?
The standard form of an argument is a way of presenting the argument which makes clear which propositions are premises, how many premises there are and which proposition is the conclusion. In standard form, the conclusion of the argument is listed last.
Q. How do you tell if an argument is valid using a truth table?
In general, to determine validity, go through every row of the truth-table to find a row where ALL the premises are true AND the conclusion is false. Can you find such a row? If not, the argument is valid. If there is one or more rows, then the argument is not valid.
Q. Does an argument have to be valid to be good?
Remember for an argument to be good, it must be valid (or strong) AND have true premises. If we judge the argument to be valid, and the lawyer can establish the truth of each premise, it will be difficult to deny the conclusion, unless some new information is presented.
Q. How do you determine the validity of an argument?
Work out the truth-values of premises and conclusion on each row. Check to see if there are any rows on which all of the premises are true and the conclusion false (counterexamples). If there are any counterexample rows, the argument is formally invalid. If there are none, it’s formally valid.
Q. How do you know if an argument is strong or weak?
Definition: A strong argument is a non-deductive argument that succeeds in providing probable, but not conclusive, logical support for its conclusion. A weak argument is a non-deductive argument that fails to provide probable support for its conclusion.
Q. Which of the following is the best definition of validity?
Which of the following is the best definition of validity? An argument is valid if and only if the truth of its premises guarantees the truth of the conclusion.
Q. What is the importance of validity?
