What is a priori meaning?

A priori meaning refers to knowledge or reasoning that is based on logical deduction or self-evidence rather than on experience or empirical evidence. This means that a priori knowledge is considered to be true before any experience or observation is considered, and its truth is not dependent on any particular experience. For example, the knowledge that all bachelors are unmarried is a priori knowledge, as it can be logically deduced without the need for empirical evidence. The concept of a priori meaning is commonly studied in philosophy and is considered important in fields such as mathematics and logic.
