Another quote from the great proponent of Republican Government - Marcus Tullius Cicero

Cicero in re Power and Law

        Power and law are not synonymous. In truth they are frequently in opposition and irreconcilable. There is God's Law from which all Equitable laws of man emerge and by which men must live if they are not to die in oppression, chaos and despair. Divorced from God's eternal and immutable Law, established before the founding of the suns, man's power is evil no matter the noble words with which it is employed or the motives urged when enforcing it. 

        Men of good will, mindful therefore of the Law laid down by God, will oppose governments whose rule is by men, and if they wish to survive as a nation they will destroy the government which attempts to adjudicate by the whim of venal judges.

Marcus Tullius Cicero 106-43 B.C.
