  3. 3. Four Kinds of Logical Opposition 1. Contrary Opposition 2. Contradictory Opposition 3. Sub- Contrary Opposition 4. Sub- Altern Opposition
  4. 4. 1. Contrary Opposition One which exist between two universal proposition that differ in quality Two propositions with the same subjects and predicates but different qualities and having the same universal quantities.
  5. 5. Rules: a. Contrary proposition cannot be true together. b. Contrary propositions can be false together.
  6. 6. Examples: A: All Cats are Dogs. (F) A: All Diamonds are Gems. (T) E: No Cats are Dogs. (T) E: No diamonds are Gems. (F) A: All Flowers are Roses. (F) E. No Flowers are Roses. (F) Thus, “If one is true the other is false; If one is false the other is doubtful.”
  7. 7. 2. Contradictory Opposition  One which exist between two proposition that differ in both quality or quantity Two propositions with the same subjects and predicates but different in quantities and in qualities.
  8. 8. Rules: a. Contradictory proposition cannot be true together. b.Contradictory proposition cannot be false together.
  9. 9. Example: A: All Dogs are Animals. (T) O: Some Dogs are not Animals. (F) E: no women are married. (F) I. Some Women are married. (T) Thus, “If one is true the other is false or vice versa.”
  10. 10. 3. Sub- Contrary Proposition One which exist between two particular propositions that differ only in quality. Two particular propositions with the same subjects and predicates but different qualities.
  11. 11. Rules: a. Sub-Contrary Proposition cannot be false together. b.Sub-Contrary proposition may be true together.
  12. 12. Examples: I: Some Basketball Players are tall. (T) O: Some Basketball Players are not tall. O: Some Triangles are not Squares. (T) I; Some Triangles are Squares. (F) I: Some Students are present. (F) O: Some Students are not present. (T) Thus, “If one is true the other is false; If one is true the other is doubtful.”
  13. 13. 4. Sub- Altern Opposition One which exist between two propositions that differ in quality. Two propositions with the same subjects and Predicates both with the same qualities and different only in qualities.
  14. 14. Rules: a. Sub-Altern Proposition cannot be false together. b.Sub-Altern Proposition can be true together.
  15. 15. Examples: A: All Dogs are Animals.(T) I: Some Dogs are Animals. (T) E: No Cats are Dogs. (T) O: Some Cats are not Dogs. (T) Thus, “If the universal is true the particular is true but if the universal is false, the particular is doubtful or vice versa.
