“Action is purposive conduct. It is not simply behavior, but behavior begot by judgments of value, aiming at a definite end and guided by ideas concerning the suitability or unsuitability of definite means. . . . It is conscious behavior. It is choosing. It is volition; it is a display of the will.”

-Ludwig von Mises, The Ultimate Foundation of Economic Science p. 34
