Aristotle was a Greek philosopher and scientist born in the city of Stagira, Chalkidice, on the northern periphery of Classical Greece.

We are better able to study our neighbors than ourselves, and their actions than our own.
Virtue also depends on ourselves. And so also does vice. For where we are free to act we are also free to refrain from acting, and where we are able to say No we are also able to say Yes; if therefore we are responsible for doing a thing when to do it right, we are also responsible for not doing it when not to do it is wrong, and if we are responsible for rightly not doing a thing, we are also responsible for wrongly doing it.
Any change of government which has to be introduced should be one which men, starting from their existing constitutions, will be both willing and able to adopt, since there is quite as much trouble in the reformation of an old constitution as in the establishment of a new one, just as to unlearn is as hard as to learn.
They should rule who are able to rule best.
The proof that you know something is that you are able to teach it
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.
A tragedy is the imitation of an action that is serious, and also, as having magnitude, complete in itself . . . with incidents arousing pity and terror, with which to accomplish its purgation of these emotions.
Dignity consists not in possessing honors, but in the consciousness that we deserve them.
We should behave to our friends as we would wish our friends to behave to us
Wicked men obey from fear; good men, from love.
