LessonsFronting, Kull and Negation: Denial of Universality versus Universal DenialQuiz

Kull invokes totality or the members of a class distributively. Its interaction with negation depends on which element falls within the other's scope.

There are two main possibilities:
1. Denying the predicate of every member of a group.
2. Denying that the predicate holds for all members as a group: universal affirmation fails.

These are logically different. The first leaves no member affirmed, while the second may still allow the predicate to hold for some members.
