Aristotle

Aristotle
Aristotle was a Greek philosopher and scientist born in the city of Stagira, Chalkidice, on the northern periphery of Classical Greece. His father, Nicomachus, died when Aristotle was a child, whereafter Proxenus of Atarneus became his guardian. At eighteen, he joined Plato's Academy in Athens and remained there until the age of thirty-seven. His writings cover many subjects – including physics, biology, zoology, metaphysics, logic, ethics, aesthetics, poetry, theater, music, rhetoric, linguistics, politics and government – and constitute the first comprehensive system...

It is evident that the state is a creation of nature, and that man is by nature a political animal.
The best political community is formed by citizens of the middle class.
A democracy exists whenever those who are free and are not well-off, being in the majority, are in sovereign control of government, an oligarchy when control lies with the rich and better-born, these being few.
The right constitutions, three in number- kingship, aristocracy, and polity- and the deviations from these, likewise three in number - tyranny from kingship, oligarchy from aristocracy, democracy from polity.
.. for desire is like a wild beast, and anger perverts rulers and the very best of men. Hence law is intelligence without appetition.
Perhaps here we have a clue to the reason why royal rule used to exist formerly, namely the difficulty of finding enough men of outstanding virtue ..
A man who examines each subject from a philosophical standpoint cannot neglect them: he has to omit nothing, and state the truth about each topic.
It is clear that those constitutions which aim at the common good are right, as being in accord with absolute justice; while those which aim only at the good of the rulers are wrong.
Phronimos, possessing practical wisdom . But the only virtue special to a ruler is practical wisdom; all the others must be possessed, so it seems, both by rulers and ruled. The virtue of a person being ruled is not practical wisdom but correct opinion; he is rather like a person who makes the pipes, while the ruler is the one who can play them.
To leave the number of births unrestricted, as is done in most states, inevitably causes poverty among the citizens, and poverty produces crime and faction.
The society that loses its grip on the past is in danger, for it produces men who know nothing but the present, and who are not aware that life had been, and could be, different from what it is.
A state is not a mere society, having a common place, established for the prevention of mutual crime and for the sake of exchange. . . .Political society exists for the sake of noble actions, and not mere companionship.
People of superior refinement and of active disposition identify happiness with honour; for this is roughly speaking, the end of political life.
Politicians also have no leisure, because they are always aiming at something beyond political life itself, power and glory, or happiness.
