Nor was civil society founded merely to preserve the lives of its members; but that they might live well: for otherwise a state might be composed of slaves, or the animal creation... nor is it an alliance mutually to defend each other from injuries, or for a commercial intercourse. But whosoever endeavors to establish wholesome laws in a state, attends to the virtues and vices of each individual who composes it; from whence it is evident, that the first care of him who would found a city, truly deserving that name, and not nominally so, must be to have his citizens virtuous.
Aristotle (384 BCE - March 7, 322 BCE) was an ancient Greek philosopher, a student of Plato and teacher of Alexander the Great. He wrote on diverse subjects, including physics, poetry, biology and zoology, logic, rhetoric, politics and government, and ethics. Along with Socrates and Plato, Aristotle was one of the most influential of ancient Greek philosophers. They transformed Presocratic Greek philosophy into the foundations of Western philosophy as we know it. Some consider Plato and Aristotle to have founded two of the most important schools of Ancient philosophy; others consider Aristotelianism as a development and concretization of Plato's insights.
