Helmut - is isn't a mathematical question but a logical question.
Look up: 'Logica Ponens and the fallacy of affirming the consequent.
As an example of your If A then B, try: 'If it rains my car is wet."
But my car is wet [B] is false since my car is in the garage.

Jon, I think I mean: "A is true", "B is false", "C=(if A then B)",
"if C then B". Is C false, because something true cannot have
something false for consequence? Or may C be true, because a
falsity is a false connection of truths, without which it could not
exist? Best, Helmut 28. Februar 2019 um 17:58 Uhr

Helmut: By "B is a fault," do you mean "B is false"? By "B
derives from A," do you mean "if A then B"? By "C is a subset of B,"
do you mean "if C then B"? If these are accurate translations, and A
is true but B is false, then there is no paradox--it is false that B
derives from A; i.e., C is false. Regards, Jon Alan Schmidt

fault, or is this question a paradox? Best, Helmut
