Apodicticity
（重定向自Apodictic）
"Apodictic" or "apodeictic" (Ancient Greek: ἀποδεικτικός, "capable of demonstration") is an adjectival expression from Aristotelean logic that refers to propositions that are demonstrable, that are necessarily or self-evidently the case or that, conversely, are impossible. Apodicticity or apodixis is the corresponding abstract noun, referring to logical certainty.
