Error 1: Calling every immā statement a genuine disjunction. Correction: genuine disjunction excludes both joint truth and joint falsehood.
Error 2: Treating every exclusion as oppositional. Correction: an exclusion may depend on contingent circumstances.
Error 3: Treating every “if” statement as universal. Correction: an explicit quantifier determines its stated quantity.
Error 4: Treating “not always” as “never.” Correction: denying universality does not imply a universal negative.
The guiding rule is to justify each classification by the property specific to it.
