The head of a free nation's government must direct towards obscure and shifting objectives the actions of a group of people who are not compelled to obey him by anything except the fear of anarchy, which fear does not exist in times f social peace. He can do nothing without being criticized by opponents whose desire to put someone in his place makes them the more pitiless. His lieutenants are not respectful assistants; they are his equals and his eventual successors.
André Maurois
