Detailed explanation-1: -A posteriori knowledge is empirical, experience-based knowledge, whereas a priori knowledge is non-empirical knowledge. Standard examples of a posteriori truths are the truths of ordinary perceptual experience and the natural sciences; standard examples of a priori truths are the truths of logic and mathematics.

Detailed explanation-2: -a posteriori knowledge, knowledge derived from experience, as opposed to a priori knowledge (q.v.).

Detailed explanation-3: -For example, the proposition that all bachelors are unmarried is a priori, and the proposition that it is raining outside now is a posteriori. The distinction between the two terms is epistemological and immediately relates to the justification for why a given item of knowledge is held.

Detailed explanation-4: -A priori knowledge is independent from current experience (e.g., as part of a new study). Examples include mathematics, tautologies, and deduction from pure reason. A posteriori knowledge depends on empirical evidence. Examples include most fields of science and aspects of personal knowledge.

Detailed explanation-5: -a priori knowledge, in Western philosophy since the time of Immanuel Kant, knowledge that is acquired independently of any particular experience, as opposed to a posteriori knowledge, which is derived from experience.
