Interpretation Chapter
Chapter 1: Speech is the symbol of thought. Isolated thoughts or words are neither correct nor incorrect. Correctness and incorrectness are attributes of certain combinations of thoughts or words.
Chapter 2: The definition of nouns. Simple and compound nouns. Indefinite nouns. The case of nouns.
Chapter 3: The definition of verbs. Indefinite verbs. The tense of verbs. Gerunds and adjectives.
Chapter 4: The 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: The definition of singular propositions.
Chapter 9: Propositions about the present or past must be either correct or incorrect. Propositions about the future must be either correct or incorrect, but which one is correct and which one is incorrect cannot be determined.
Chapter 10: The diagrammatic arrangement of names in affirmative and negative propositions. The complement without a verb, the complement with a verb, and the complement 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 obtained by combining the predicates of these two propositions is not necessarily correct.
Chapter 12: Propositions about possibility, impossibility, contingency, and necessity. The appropriate contradictory proposition for such propositions.
Chapter 13: The format showing the relationship between such propositions. Proving the illogicality of this format. What is called possible can be constantly real; sometimes real and sometimes unreal; never real.
Chapter 14: Discussing: Is the proper opposite of a universal or particular affirmative proposition an opposite definite proposition or an opposite negative proposition?
