"The Devil, it is true, is not exactly a doctor who has taken degrees, but he is very learned, very expert for all that. He has not been carrying on his business during thousands of years for nothing."

Once efficiency is universally accepted as a rule, it becomes an inner compulsion and weighs like a sense of sin, simply because no one can ever be efficient enough, just as no one can ever be virtuous enough. And this new sense of sin only contributes further to the enervation of leisure, for the rich as well as the poor. The difficulty of carrying on a leisure-oriented tradition of culture in a work-oriented society is enough in itself to keep the present crisis in our culture unresolved.
