Middle Term

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:

    Don’t you realize that as long as you have to sit down to pee, you’ll never be a dominant force in the world? You’ll never be a convincing technocrat or middle manager. Because people will know. She’s in there sitting down.
    Don Delillo (b. 1926)

    Punks in their silly leather jackets are a cliché. I have never liked the term and have never discussed it. I just got on with it and got out of it when it became a competition.
    John Lydon (formerly Johnny Rotten)
