The task of classifying contradictory pairs continues in the chapters that follow, but no new exceptions to RCP are found. Here, assertions are examined and their contradictory pairs set out, beginning with the most basic, in which ’is’ is added to a name. Next the role of the verb ’to be’ as an ’additional predicate’ is seen, in sentences such as ’man is just’, and finally assertions are considered in which there is no ’to be’, and a verb is simply added to a name. Contradictory pairs are examined which involve the use of negative subjects as well as negative predicates, universally and non‐universally. We see here a careful discussion of the different ways in which negation can be applied in a sentence, and guidance on how to tell which assertions are the contradictories of which others.
