LessonsFurther Conditional Divisions, Quantification and Conditional QuantifiersQuiz

A conditional’s quality is whether the relation is affirmed or denied; its quantity specifies whether the judgment extends to all or some relevant cases. These are separate axes.

Universal affirmative: the relation holds in all relevant cases.
Particular affirmative: it holds in some cases.
Universal negative: it fails in all relevant cases.
Particular negative: it fails in some cases.

One must also separately determine whether the conditional is connective or disjunctive. Distinguishing kind, quality, and quantity prevents category errors.
