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:
“God forgive me, I do still see that my nature is not to be quite conquered, but will esteem pleasure above all things; though, yet in the middle of it, it hath reluctancy after my business, which is neglected by my following my pleasure. However, music and women I cannot but give way to, whatever my business is.”
—Samuel Pepys (1633–1703)
“In eloquence, the great triumphs of the art are when the orator is lifted above himself; when consciously he makes himself the mere tongue of the occasion and the hour, and says what cannot but be said. Hence the term abandonment, to describe the self-surrender of the orator.”
—Ralph Waldo Emerson (1803–1882)
