Aristotle was an ancient Greek philosopher born in 384 BCE who founded the Lyceum in Athens and wrote on many topics. He is considered one of the greatest thinkers in Western history. Aristotle viewed the state as a natural condition for humans that allows them to live a good life and fulfill their needs through cooperation and division of labor. He established political science as a discipline and believed the state's purpose was the good life of its citizens. Aristotle died in 322 BCE at age 63 in Chalcis, Greece.
