The idea of freedom can never be disassociated from real Prussia. The real Prussian spirit means a synthesis between restraint and freedom, between voluntary subordination and conscientious leadership, between pride in oneself and consideration for others, between rigor and compassion. Unless a balance is kept between these qualities, the Prussian spirit is in danger of degenerating into soulless routine and narrow-minded dogmatism.
