"A German philosopher many years ago said something to the effect that the more a man has in his own heart, the less he will require from the outside; excessive need for support from without is proof of the bankruptcy of the inner man.
If this is true (and I believe it is) then the present inordinate attachment to every form of entertainment is evidence that the inner life of modern man is in serious decline. The average man has no central core of moral assurance, no spring within his own breast, no inner strength to place him above the need for repeated psychological shots to give him the courage to go on living. He has become a parasite on the world, drawing his life from his environment, unable to live a day apart from the stimulation which society affords him."
