Logic / Unit 3 Logic 093 short lesson, about 20 seconds
Major, Minor, and Middle Terms
Captions available
The idea
The major term is the conclusion's predicate; the minor term is its subject; the middle term appears only in the premises.
In practice
In the syllogism above: P major, S minor, M middle. The major premise is stated first by convention.
Where people slip
The middle term is the engine — it links the other two and vanishes from the conclusion.
