A Posteriori: A Comprehensive Guide to Its Legal Meaning

Definition & Meaning

The term a posteriori refers to knowledge that is acquired through experience or empirical evidence.

For instance, knowing that it rains after dark clouds appear is an example of a posteriori knowledge, as it is derived from observing the relationship between the two phenomena.
