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:
““When I used to read fairy tales, I fancied that kind of thing never happened, and now here I am in the middle of one! There ought to be a book written about me, that there ought! And when I grow up, I’ll write one—but I’m grown up now,” she added in a sorrowful tone: “At least there’s no room to grow up any more here.””
—Lewis Carroll [Charles Lutwidge Dodgson] (1832–1898)
“Dead drunk
is the term I think of,
insensible,
neither cool nor warm,
without a head or a foot.
To be drunk is to be intimate with a fool.”
—Anne Sexton (1928–1974)
