Nicomachean Ethics by Aristotle

Aristotle picks up one of the biggest problems of Plato: if we have to have perfect people to make society run in an orderly fashion, how do we ever get there, or can we get there at all?

In this work, Aristotle comes up with his solution, which seeks the constant moral improvement of people and communities to attempt to make the world better. Some of his specific commentaries on how human beings out to judge one another make this a work that I think is as relevant now as when it was published first in ancient Athens, about 2500 years ago.
