  • Ch. 3. Definition of a verb. Indefinite verbs. Tenses of verbs.
  • Ch. 4. Definition of a sentence. Not every sentence a proposition.
  • Ch. 5. Of simple and complex or composite propositions.
  • Ch. 6. Of contradictory propositions.

  • Ch. 10. Affirmative and negative propositions arranged with a diagram in pairs. The correct position of the negative (οὐ). Of the truth and error of certain propositions. Of propositions with indefinite nouns or indefinite nouns and verbs. To transpose the subject and predicate makes no difference to the meaning of propositions.
  • Ch. 11. Some propositions that seem to be simple are really compound. So are some dialectical questions. The nature of dialectical questions. Two simple propositions, which have the same subject, may be true; but we cannot of necessity combine the two predicates into one predicate. Several predicates holding of one subject, when taken by themselves and individually, cannot be combined together to make up one simple proposition, unless all are essential to the subject and none is implied in another.
  • Ch. 12. Of propositions affirming or denying the possible, impossible, contingent and necessary, and of their proper contradictories.
  • Ch. 13. The relations that subsist between such propositions. The relation of the actual to the possible. Three classes of entities.
  • Ch. 14. Of the proper contrary of an affirmation, whether universal or particular.
