Roman stability, in Polybius’ assessment, was owing to the checks each element put on the superiority of any other: a consul at war, for example, required the cooperation of the Senate and the people if he hoped to secure victory and glory, and could not be indifferent to their wishes. This was not to say that the balance was in every way even: Polybius observes that the superiority of the Roman to the Carthaginian constitution (another mixed constitution) at the time of the Hannibalic War was an effect of the latter's greater inclination toward democracy than to aristocracy. Moreover, recent attempts to posit for Rome personal freedom in the Greek sense – "eleutheria": living as you like – have fallen on stony ground, since "eleutheria" (which was an ideology and way of life in the democratic Athens) was anathema in the Roman eyes. Rome's core values included order, hierarchy, discipline, and obedience. These values were enforced with laws regulating the private life of an individual. The laws were applied in particular to the upper classes, since the upper classes were the source of Roman moral examples.
