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:
“If these Essays were worthy of being judged, it might fall out, in my opinion, that they would not find much favour, either with common and vulgar minds, or with uncommon and eminent ones: the former would not find enough in them, the latter would find too much; they might manage to live somewhere in the middle region.”
—Michel de Montaigne (1533–1592)
“As the term of my relief from this place [Washington, D.C.] approaches, it’s drudgery becomes more nauseating and intolerable, and my impatience to be with you at Monticello increases daily.”
—Thomas Jefferson (1743–1826)
