The discipline of praxeology affirms the ability of the human rational faculty to deductively obtain certain knowledge about aspects of reality. Praxeology, the science of human action, begins with the action axiom. Action, exhibited by all humans, is “purposeful behavior”. An acting man perceives a certain set of ends as subjectively valuable and then chooses means that he thinks will attain those ends. The goal of all action is ultimately the satisfaction of the individual actor.
