Which formal structural error is this? Is it still considered Affirming the Consequent if they’re using negations of p and q in the second premise?
P1 If !p then !q
P2 Q
P3 Therefore p
I don't know what formal structural error this is,. It it's a non sequitur. Even if we accept P1 as true, it does not logically follow.
