Numerous experts in modern time regard Plato as the first genuine political philosopher and Aristotle as the first political scientist. They were both great thinkers, Plato and Aristotle each had ideas in how to proceed with improving the society in which they were part of during their existence. It is necessary therefore to analyze their different theoretical approaches regarding their philosophical perspectives, such as ethics and psychology. Aristotle to Plato had great theory but which ones would you agree with.
Aristotle has his philosophy for the purpose of human nature. He even explains how happiness is different for every person, and each different type of person has a different idea of eudaimonia. He then goes on to talk about how a person must do all things in moderation, not doing the excess but at the same time doing just enough. This idea, called the "golden mean of moderation" was the backbone support to Aristotle's idea of human telos because it concluded that living a virtuous life must be the same for all people because of the way human beings are built.
Aristotle argued that the goal of human beings is happiness, and that we achieve happiness when we fulfill our function. Therefore, it is necessary to determine what our function is. The function of a thing, or its telos, is what it alone can do, or what it can do best. Like the function of the eye is to see, Aristotle declared the human being as the "rational animal" whose function is to reason. Thus, according to Aristotle, a happy life for human beings is a life governed by reason. .
Aristotle believed that a person who has difficulty behaving ethically is morally imperfect. His ideal person practices the "golden mean of moderation." He believed that this moral virtue, of which happiness comes from, is a matter of avoiding extremes in behavior and finding the mean between them. Aristotle conceives happiness not primarily as an exercise of virtue in private or with friends, but as the exercise of virtue in governing an ideal state.
