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:
“You can always tell a Midwestern couple in Europe because they will be standing in the middle of a busy intersection looking at a wind-blown map and arguing over which way is west. European cities, with their wandering streets and undisciplined alleys, drive Midwesterners practically insane.”
—Bill Bryson (b. 1951)
“Narcissist: psychoanalytic term for the person who loves himself more than his analyst; considered to be the manifestation of a dire mental disease whose successful treatment depends on the patient learning to love the analyst more and himself less.”
—Thomas Szasz (b. 1920)
