No, Your inability to define formal systems means you are bad at logic.

You have never been able to define "formal system", despite many,
many requests to do so. Giving *a* property that a formal system has is
in no way a definition of formal system.  Especially since it is a property
that has been implied false by some of your Olcutt Formal System hand-wavings.

Please give your definition of "formal system"
