  1. Validity and Conditionals There is a relationship between validity of an argument and a corresponding conditional.

  2. Validity and Conditionals There is a relationship between validity of an argument and a corresponding conditional. Argument: P, -P>-Q | Q Corresponding Conditional: (P&(-P>-Q))>Q

  3. Validity and Conditionals There is a relationship between validity of an argument and a corresponding conditional. Argument: P, -P>-Q | Q Corresponding Conditional: (P&(-P>-Q))>Q An argument is valid iff its corresponding conditional is a logical truth.

  4. Example Argument: P, -P>-Q | Q Corresponding Conditional: (P&(-P>-Q))>Q An argument is valid iff its corresponding conditional is a logical truth. P Q P & (-P > -Q)) > Q P -P>-Q | Q T F T F T T F F T F T F * T F T T * T T F F *

  5. Example Argument: P, -P>-Q | Q Corresponding Conditional: (P&(-P>-Q))>Q An argument is valid iff its corresponding conditional is a logical truth. P Q P & (-P > -Q)) > Q P -P>-Q | Q T F T F T T F F T F T F T F T T T T F F T F T F * T F T T * T T F F *
