Will Herberg, Judaism and Modern Man - An Interpretation of Jewish Religion

"The attempt made in recent decades by secularist thinkers to disengage the moral principles of western civilization from their scripturally based religious context, in the assurance that they could live a life of their own as "humanistic" ethics, has resulted in our "cut flower culture." Cut flowers retain their original beauty and fragrance, but only so long as they retain the vitality that they have drawn from their now-severed roots; after that is exhausted, they wither and die. So with freedom, brotherhood, justice, and personal dignity — the values that form the moral foundation of our civilization. Without the life-giving power of the faith out of which they have sprung, they possess neither meaning nor vitality."
