What is Man? - Martin Buber

Individualism understands only a part of man; collectivism understands man only as a part. Neither advances to the wholeness of man, to man as a whole. Individualism sees man only in relation to himself; but collectivism does not see man at all - it sees only society. The fundamental fact of human existence is neither the individual as such nor the aggregate as such. The fundamental fact of human existence is man-with-man.
