CONSTRAINTS ON LOGIC: THE PRIMACY OF OPERATIONALISM

Try this:
1) All syllogistic (verbal, set) logic is either tautological or contingent upon premises.
2) All axiomatic logic is contingent upon axioms.
3) All operational logic from first principles is not contingent – it’s either constructible or not: surviving falsification or not.

See?
Everythign we state in P-law is constructed from first principles in operational prose.
We don’t necessarily need to know something is true.
But we can pretty securely say it’s false.
