We, on the other hand, must take for granted that the things that exist by nature are, either all or some of them, in motion.
AristotleThe goodness or badness, justice or injustice, of laws varies of necessity with the constitution of states. This, however, is clear, that the laws must be adapted to the constitutions. But if so, true forms of government will of necessity have just laws, and perverted forms of government will have unjust laws.
Aristotle
