Disjunctive Inference
To the glossary index · ↑ Top of page
The highest form of the inference of necessity. It grounds a conclusion through the systematic exclusion of all alternatives. "A is either B, C, or D; A is not B and not C; therefore A is D." It presupposes a complete articulation (disjunction) of the universal. This is the basic structure of the "Detective Principle."
Origin: Classical logic (*modus tollendo ponens*). Hegel (highest form of the subjective inference).
