In logic, a middle term is a term that appears (as a subject or predicate of a categorical proposition) in both premises but not in the conclusion of a categorical syllogism. The middle term (in bold below) must be distributed in at least one premise but not in the conclusion. The major term and the minor terms, also called the end terms, do appear in the conclusion.
Example:
- Major premise: All men are mortal.
- Minor premise: Socrates is a man.
- Conclusion: Socrates is mortal.
The middle term is bolded above.
Famous quotes containing the words middle and/or term:
“In the middle classes the gifted son of a family is always the poorest—usually a writer or artist with no sense for speculation—and in a family of peasants, where the average comfort is just over penury, the gifted son sinks also, and is soon a tramp on the roadside.”
—J.M. (John Millington)
“I am a colored woman or a Negro woman. Either one is OK. People dislike those words now. Today these use this term African American. It wouldn’t occur to me to use that. I prefer to think of myself as an American, that’s all!”
—Annie Elizabeth Delany (b. 1891)
