The a priori/a posteriori distinction is sometimes applied to things other than ways of knowing, for instance, to propositions and arguments. An a priori proposition is one that is knowable a priori and an a priori argument is one the premises of which are a priori propositions. Correspondingly, an a posteriori proposition is knowable a posteriori, while an a posteriori argument is one the premises of which are a posteriori propositions.
A priori justification and knowledge of propositions of the form âAll A s are B sâ seem to be justification and knowledge of conditionals that have no existential import and are of the form, â If something is an A, then it's a B â.ecause most philosophers believe that knowledge requires justification, it is widely thought that a priori knowledge is just a special kind of knowledge, namely, knowledge that is based solely on a priori justification.
