Interpretation Chapter
Chapter 1: Ordinary language is the symbol of thought. Isolated thoughts or terms are neither correct nor incorrect. Correctness and incorrectness are attributes of certain combinations of thoughts or words.
Chapter 2: Definition of nouns: simple and compound nouns, indefinite nouns, and the case of nouns.
Chapter 3: Definition of verbs: indefinite verbs, verb tenses, gerunds, and adjectives.
Chapter 4: Definition of sentences.
Chapter 5: Simple and compound propositions.
Chapter 6: Contradictory propositions.
Chapter 7: Universal, indefinite, and particular affirmative and negative propositions. Opposite propositions are different from contradictory propositions. In two opposite propositions with universal or particular subjects, the correctness of one implies the incorrectness of the other. But this is not the case with indefinite propositions.
Chapter 8: Definition of singular propositions.
Chapter 9: Propositions about the present or past must be either correct or incorrect, while propositions about the future must also be either correct or incorrect, though which is which cannot be determined.
Chapter 10: Diagrammatic arrangement of names in affirmative and negative propositions. Those without a verb are complements, while those with a verb are complements of the verb, with an indefinite noun as the subject.
Chapter 11: Some seemingly simple propositions are actually compound. Similarly, some dialectical questions are actually compound. The nature of dialectical questions. When both of two simple propositions with the same subject are correct, the proposition derived from the combination of their predicates is not necessarily correct.
Chapter 12: Propositions about possibility, impossibility, contingency, and necessity. Determining the appropriate contradictory proposition for such propositions.
Chapter 13: Formulas showing the relationships between such propositions. Proving the illogicality of this formula. That which is called possible can be constantly real, sometimes real and sometimes unreal, or never real.
Chapter 14: Discussion: Is the proper opposite of a universal or particular affirmative proposition an opposite definite proposition or an opposite negative proposition?
