Aristotle was born in Stagira, in northern Greece, in 384 BCE. His father was a physician at the court of Amyntas III of Macedon, and in 367 Aristotle moved to Athens to study at Plato's Academy. He remained there for twenty years, until Plato's death in 347. Aristotle's published works were all lost or destroyed several centuries after his death, and all that remained were his lectures, or notes on the lectures, which Aristotle gave to the Lycée. These works were first collected by Andronicus of Rhodes, about two centuries after his death, and we do not know the chronology of his work. Aristotle's works are vast and thought-provoking; In "The Purpose of Man", Aristotle formed the idea of ​​happiness not only based on the exercise of virtue in an individual's private life, such as among friends and family. He focused on happiness as the exercise of virtue in order to govern an ideal state. I argue that the best states are based on the mutual interests of each person who has the same interests as everyone else, and these interests are closely related to each other. Indeed, a person who acts for his own good must also act for the good of his fellow citizens, which leads to the construction of an ideal state. The ideal state is either an aristocracy or a monarchy, and Aristotle states that the decision for the state depends on what the citizens prefer. The choice between these two elements is the key to an ideal state because it allows citizens to realize the greatest value; there is only one person with truly exceptional abilities who must rule as king, or multiple rulers share power. The best constitution for a state depends on the moral qualities of the citizens. The main question is not which constitution is best suited for the governance of a state...... middle of paper ......lly defined as success and fulfillment. Therefore, happiness was not truly an emotional state, because happiness meant that they were living successfully. This emphasizes that happiness is an action or practice of virtue for the good of citizens and society. While happiness is the act of living successfully or well, virtue resembles the potential to live well. Excelling in all moral virtues is a good thing, but it does not guarantee our happiness unless we exercise those virtues. Courageous people who never test their courage by facing fear have virtue, but they are not happy. Aristotle illustrates this distinction between happiness and virtue by saying that the virtuous win if they compete and practice the virtues. Happiness awaits only those who go out and grab it. Happiness is the highest good and the end to which our actions ultimately aim..
