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

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

4. 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.
