Invalid Argument/Examples/I am Not Famous

Example of Invalid Argument
The following is an invalid argument with true premises and a true conclusion:


 * If I am President then I am famous.
 * I am not President.


 * Therefore I am not famous.

Proof
This is an example of Denying the Antecedent.

It does not follow that just because I am not President then I am not famous.

The fact that I am indeed not famous is independent of the argument.
