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:
“The goods of fortune ... were never intended to be talked out of the world.—But as virtue and true wisdom lie in the middle of extremes,—on one hand, not to neglect and despise riches, so as to forget ourselves,—and on the other, not to pursue and love them so, as to forget God;Mto have them sometimes in our heads,—but always something more important in our hearts.”
—Laurence Sterne (1713–1768)
“We now demand the light artillery of the intellect; we need the curt, the condensed, the pointed, the readily diffused—in place of the verbose, the detailed, the voluminous, the inaccessible. On the other hand, the lightness of the artillery should not degenerate into pop-gunnery—by which term we may designate the character of the greater portion of the newspaper press—their sole legitimate object being the discussion of ephemeral matters in an ephemeral manner.”
—Edgar Allan Poe (1809–1845)
