What is good? How do we know what good is? How can we achieve good? What are the main obstacles to achieving good? These questions have great practical importance for individual life as well as for collective life. However, disagreements arise when it comes to answering these questions. Throughout history, philosophers, theologians, and other thinkers have attempted to resolve these disagreements by proposing their own “new” understandings of what is Good? In this essay, I will explain how Aristotle and Augustine understood this ideal and how they answered these questions. In the first two parts of the essay, I will examine the conceptual framework of these two philosophers and attempt to explain how they answered the questions mentioned above. In the last part, I will try to answer this question: which of the two philosophers do I agree with and why? We pursue different goals in our life i.e. wealth, knowledge, honor etc. All of these goals could be described as good, but “by asking this question: what is the point?” — Aristotle is not looking for a list of elements that are good. Its aim is to establish a standard for what might be called the highest good, that is, it seeks the form of good. In his first book on the Nicomachean Ethics, Aristotle describes that the Good is something “for which everything else is done.” This shows that he considers good as the first principle of all our actions. He mentions: “Happiness is therefore something final and self-sufficient, and it is the end of the action. » He therefore identifies happiness as the highest good to which all other goals are subordinate. "From here we could identify three characteristics of the highest good: "it is desirable for its own sake, it is...... middle of paper...... the person is a king or a working peasant in the fields. Thus, for Augustine, the highest good could be achieved by every human being if he directs all his love towards God. The possibility that every person has the potential to become fully human is one of the features that distinguishes this framework from Aristotle's. (ed.), forthcomingURL.Ross, David (1925).
