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...

So it is clear that the search for what is just is a search for the mean; for the law is the mean.
Property should be in a general sense common, but as a general rule private... In well-ordered states, although every man has his own property, some things he will place at the disposal of his friends, while of others he shares the use of them.
Men pay most attention to what is their own: they care less for what is common; or, at any rate, they care for it only to the extent to which each is individually concerned.
Therefore, the good of man must be the end of the science of politics.
Now property is part of a household, and the acquisition of property part of household-management; for neither life itself nor the good life is possible without a certain minimum supply of the necessities.
...the life which is best for men, both separately, as individuals, and in the mass, as states, is the life which has virtue sufficiently supported by material resources to facilitate participation in the actions that virtue calls for.
Poverty is the parent of revolution and crime.
The search for truth is in one way hard and in another way easy, for it is evident that no one can master it fully or miss it wholly. But each adds a little to our knowledge of nature, and from all the facts assembled there arises a certain grandeur.
Every action must be due to one or other of seven causes: chance, nature, compulsion, habit, reasoning, anger, or appetite.
Personal beauty is a greater recommendation than any letter of introduction
Teachers who educate children deserve more honor than parents who merely gave birth; for bare life is furnished by the one, the other ensures a good life
A true friend is one soul in two bodies.
