The first substantial group of semantic fallacies requires separate analysis of matter and form. A premise can be true in one respect but illegitimately deployed in another, and true premises can be arranged in a form that proves nothing.
The characteristic examples are the qualified use of “rational,” the unproductive time-and-sphere inference, begging the question, accidental motion of the passenger, incomplete repetition of the middle term, potential versus actual speech, the scope of “alone,” logical predicates of universals, and misplaced negation.
The following source section continues with mental considerations, part–whole and causal errors, priority relations, and famous fallacies. These belong to the remaining discussion of errors arising from meaning.
