Contingent

Contingent. A statement is contingent iff it is neither a logical truth nor a contradiction. Contingent. A statement is contingent iff it is neither a logical truth nor a contradiction. So the output row for a contingent statement must contain at least one F and at least one T.

  1. Contingent A statement is contingent iff it is neither a logical truth nor a contradiction.

  2. Contingent A statement is contingent iff it is neither a logical truth nor a contradiction. So the output row for a contingent statement must contain at least one F and at least one T.

  3. Contingent A statement is contingent iff it is neither a logical truth nor a contradiction. So the output row for a contingent statement must contain at least one F and at least one T. Sample contingent statement: P>Q

  4. Contingent To show a statement A is contingent ... with a table: The output row for A has a F and a T.

  5. Contingent To show a statement A is contingent ... with a table: The output row for A has a F and a T. with a proof: No proof test is possible.

  6. Contingent To show a statement A is contingent ... with a table: The output row for A has a F and a T. with a proof: No proof test is possible. There is also no proof test for invalidity.

  7. Contingent To show a statement A is contingent ... with a table: The output row for A has a F and a T. with a proof: No proof test is possible. with a tree: The tree for -A is open and the tree for A is open.

  8. Contingent To show a statement A is contingent ... with a table: The output row for A has a F and a T. with a proof: No proof test is possible. with a tree: The tree for -A is open and the tree for A is open. Common Mistake: The tree has one open and one closed branch.

  9. Contingent To show a statement A is contingent ... with a table: The output row for A has a F and a T. with a proof: No proof test is possible. with a tree: The tree for -A is open and the tree for A is open. Common Mistake: The tree has one open and one closed branch. WRONG! You need to do TWO trees.

  10. Contingent To show a statement A is contingent ... with a table: The output row for A has a F and a T. with a proof: No proof test is possible. with a tree: The tree for -A is open and the tree for A is open. A is not a logical truth and A is not a contradiction.

  11. Contingent To show a statement A is contingent ... with a table: The output row for A has a F and a T. with a proof: No proof test is possible. with a tree: The tree for -A is open and the tree for A is open. A is not a logical truth and A is not a contradiction.

  12. Contingent To show a statement A is contingent ... with a table: The output row for A has a F and a T. with a proof: No proof test is possible. with a tree: The tree for -A is open and the tree for A is open. A is not a logical truth and A is not a contradiction.

  13. Contingent To show a statement A is contingent ... with a table: The output row for A has a F and a T. with a proof: No proof test is possible. with a tree: The tree for -A is open and the tree for A is open. Sample: Here are trees that show that P>Q is contingent. -(P>Q) P -Q P>Q -P Q open open
