Epistemology, Praxeology, & Empiricism in the Social Sciences Will Porter 2/3/2014The primary task of epistemology is to construct a theory of knowledge that describes its nature and how it is attained. Ludwig von Mises, the founder of the science of Praxeology and master of Austrian School economics, delved into matters which had implications reaching beyond mere economics. Praxeology, the study of the logical implications of human action, provides insight into other areas of philosophy and gives us a foundation for epistemology by distinguishing between that which can be known a priori and that which can be known only a posteriori. A priori here refers to something that is knowable prior to any particular experience, whereas a posteriori knowledge is only known posterior to, or after some specific experience or empirical observation.The ways in which we go about attaining knowledge are different for the two areas of truth. For example, the claim that nothing can be both red all over and green all over at the same time is something that can be known just by thinking about it. In the study of logic, this is known as the Law of Contradiction and states that nothing can simultaneously be itself and its opposite. It is an example of truth which is knowable prior to any given experience.
