Original sentence: Cicero remained the ”Republic's last true friend”  as he spoke out for his own ideals and that of the libertas(freedom) the Romans had enjoyed for centuries.Cicero's idea of the concordia ordinum was too idealistic.However, Cicero was also too idealistical  to believe that ‘the best men’ would institute large-scale reforms which were contrary to their interests as the ruling oligarchy.That “some sort of free-state” ( we would nowadays call it a democratical state) is the necessary condition of a noble and honourable existence; and that it is the worst calamity for a people to permanently renounce this ideal and to substitute for it the slave’s ideal of a good master.Thirdly, he and all his contemporaries were unable to realise that Rome had grown far too large to be governed by the institutions that were originally created for governing a small town
