Empirical evidence for a proposition is evidence, i.e. what supports  this proposition, that is empirical, i.e. constituted by or accessible to sense experience or experimental procedure. Empirical evidence is of central importance to the sciences and plays a role in various other fields, like epistemology and law. Empirical evidence is essential to a posteriori knowledge or empirical knowledge, knowledge whose justification  depends on experience  . A priori knowledge, on the other hand, is seen either as innate or as justified by rational intuition and therefore as not dependent on empirical evidence. Rationalism fully accepts that there is knowledge a priori, which is either outright rejected by empiricism or accepted only in a restricted way as knowledge of relations between our concepts but not as pertaining to the external world.
