A Posteriori Definition

A posteriori is a Latin phrase that means “from the later.” It refers to knowledge gained following the analysis of an issue. It is the opposite of A Priori, which is knowledge obtained prior an analysis. It is deemed to be experiential whereas its opposite – a priori is deemed to be universal.

A Little More on What is A Posteriori

As knowledge gained after the analysis of an issue, it is understood to be synonymous with knowledge acquired via experience.

In philosophy, a posteriori refers to the type of knowledge acquired through experience and the analysis of facts. In this regard, it derives from inductive reasoning. It is very much unlike a priori, which is knowledge gained purely on reason and does not require the validation through experience. Plainly stated, a posteriori requires experiences in order to be valid.

Postulation made a posteriori are generally supported by anecdotal and empirical evidence. For instance: “Some people are tall” is an a posteriori statement validated by the experience of encountering individuals that exceed what you perceive to be the average height.
