To the average person knowledge itself is of importance because of its bearing upon what h

e needs to do and to make. It helps him in clarifying his wants, in constructing his ends and in finding means for realizing them. There exist, in other words, values as well as known facts and principles, and philosophy is concerned primarily with values--with the ends for the sake of which man acts. Given the most extensive and accurate system of knowledge, man is still eonfionted with the question of what he is going to do about it and what he is going to do with the knowledge in his possession.
