 In contrast, the term "a posteriori" is Latin for 'from what comes later' (or 'after experience').They appear in Latin translations of Euclid's "Elements", of about 300 BC, a work widely considered during the early European modern period as the model for precise thinking.An early philosophical use of what might be considered a notion of "a priori" knowledge (though not called by that name) is Plato's "theory of recollection", related in the dialogue "Meno" (380 BC), according to which something like "a priori" knowledge is knowledge inherent, intrinsic in the human mind.
