PHIL 1200 Chapter Notes - Chapter 7,9: Abbreviation, Venn Diagram, Categorical Logic
Document Summary
The system of categorical logic developed by aristotle is the study of arguments composed of sentences that state relationships between categories of things. A word is vague if it has borderline cases. Cases where it is not clear whether the word applies or does not apply. A word or term is ambiguous when it can be interpreted in two or more ways: it has two or more meanings, and we are not sure which is intended. Begin with precise definitions for all important terms. Organize results precisely on tables, charts, and in figures. Four basic ways to construct a sentence of a categorical argument: 1. State that all the members of one given category belongs to a second category: 2. State that none of one category belongs to a second category: 3. State that some of one category belong to a second category: 4. State that some of one category do not belong to a second category.
