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:
“Our children do not want models of perfection, neither do they want us to be buddies, friends, or confidants who never rise above their own levels of maturity and experience. We need to walk that middle ground between perfection and peerage, between intense meddling and apathy—the middle ground where our values, standards, and expectations can be shared with our children.”
—Neil Kurshan (20th century)
“It’s given new meaning to me of the scientific term black hole.”
—Don Logan, U.S. businessman, president and chief executive of Time Inc. His response when asked how much his company had spent in the last year to develop Pathfinder, Time Inc.’S site on the World Wide Web. Quoted in New York Times, p. D7 (November 13, 1995)
