The purely emotional form of Pietism is, as Ritschl has pointed out, a religious dilettantism for the leisure class.
Max WeberThe impulse to acquisition, pursuit of gain, of money, of the greatest possible amount of money, has in itself nothing to do with capitalism. This impulse exists and has existed among waiters, physicians, coachmen, artists, prostitutes, dishonest officials, soldiers, nobles, crusaders, gamblers, and beggars.
Max WeberCapitalism may even be identical with the restraint, or at least a rational tempering, of this irrational impulse. But capitalism is identical with the restraint, or at least a rational tempering, of this irrational impulse. But capitalism is identical with the pursuit of profit, and forever renewed profit, by means of continuous, rational, capitalistic enterprise.
