[Superman]

We could have fun with this. Logically, since this statement is a generalization, it could not possibly be true. Therefore, it is false. That is....if all generalizations are false, then this generalization is false also. And so, we know with certainty it is false.

But if this statement is undeniably false, then there must be at least one generalization which is true. Right?

What generalization is true?
