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:
“At middle night great cats with silver claws,
Bodies of shadow and blind eyes like pearls,
Came up out of the hole, and red-eared hounds
With long white bodies came out of the air
Suddenly, and ran at them and harried them.”
—William Butler Yeats (1865–1939)
“Orlando. Who stays it still withal?
Rosalind. With lawyers in the vacation; for they sleep
between term and term, and then they perceive not how Time
moves.”
—William Shakespeare (1564–1616)
