A
logical fallacy in which the
predicate term of the
conclusion of a
categorical syllogism is a
universal, but the same term in the
premises is a
particular.
Example:
All women are mortals.
No men are women.
Therefore, no men are mortals.
To prove the major illicit, show that there may be members of the predicate category not mentioned in the premises which are contrary to the conclusion. In the above example, "Socrates was a man, and he was mortal, so it is not true that no men are mortals."
