- adj. Justified by appeal to experience.
- adj. Knowable from experience.
Century Dictionary and Cyclopedia
- n. Literally, from the latter or subsequent; hence, in logic, from a consequent to its antecedent, or from an effect to its cause: used of reasoning which follows this order, formerly called demonstratio quia, or imperfect demonstration. The phrase is also used adjectively: as, a posteriori reasoning. As applied by Kant and all modern writers to knowledge, it is equivalent to from experience, or empirical; and it is opposed by him to a priori, that is, from the intellect independently of all experience. See
a priori .

Examples
“I say special training, meaning, that which takes up the subject scientifically, with a priori, and a posteriori evidence: -- of things not seen -- with homiletical and hermaneutical arrangement, and discussion in sermonizing.”
“But if the term proof or demonstration may be, as it often is, applied to a posteriori or inductive inference, by means of which knowledge that is not innate or intuitive is acquired by the exercise of reason, then it cannot fairly be denied that Catholic teaching virtually asserts that God's existence can be proved.”
The Catholic Encyclopedia, Volume 6: Fathers of the Church-Gregory XI
“But the difficulty is with regard to this preliminary admission, which if challenged -- as it is in fact challenged by Agnostics -- requires to be justified by recurring to the a posteriori argument, i.e. to the inference by way of causality from contingency to self-existence and thence by way of deduction to infinity.”
The Catholic Encyclopedia, Volume 6: Fathers of the Church-Gregory XI
“Well, Aries Tottle flourished supreme until the advent of one Hog, surnamed the 'Ettrick Shepherd', who preached an entirely different system, which he called the a posteriori or inductive.”
“+ The subjective a posteriori method, which, from an examination of the phenomena of consciousness builds up empirically, that is, inductively, conclusions based on those phenomena;”
