Hypothesis 1: False
formulas are unprovable.
Hypothesis 2:
Formula A is unprovable.
3. If A is false
then A is not-unprovable.
4. Then, by modus
tollens H2 and 3.: A is true.
5. Ergo, when A is
true it is unprovable.
We cannot define
provability in semantical terms.
The concept of provability has only syntactical meaning, therefore is useless for life.
