A priori proposition

A priori propositions have traditionally been defined as those which can be known independent of experience. A priori propositions can be contrasted to a posteriori propositions; the later being those which are gained through experience. An alternative definition of a priori propositions, which is popular among many contemporary philosophers, makes the distinction that rather than being completely independent or prior to experience, an a priori proposition is one which can be grasped independently of the character of an individual's experience. The reason for the alternative definition can be explained in the following manner:

In the case of a priori propositions, much experience, perhaps of a specific character, may be required to grasp the concepts implicated in the proposition or to access the entitlement to believe it; but conditions of grasp and of access remain distinct from the nature of the entitlement.
