This research paper studies the complex and sometimes confusing relationship between Plato’s ideas and the role of poetry in an ideal state. As we all know, philosophy and art often go in different directions, and this is clearly seen in Plato’s thinking. By looking at important works like The Republic, Ion, and Phaedrus, the study explains the “Ancient Quarrel” between philosophy and poetry. It mainly focuses on why Plato suggested removing imitative artists from the Kallipolis. The analysis explains this idea in three simple parts: first, the question of reality and how things exist; second, the problem that artists may not have true knowledge; and third, the concern that poetry can affect the human soul in a negative way, which is commonly discussed even in our country today. The paper also says that Plato was not against beauty as such, but he was more concerned about truth and the balance of the human mind. Interestingly, it shows a kind of contradiction, because Plato himself uses stories and dialogue to question poets. This is something very interesting to observe. At the same time, the study points out a “Third Realm” where some forms of art, like songs praising good values, are allowed because they help society stay united. In the end, the research reminds us that art has strong influence over human thinking, sometimes even beyond logic, and this idea is still very relevant today, especially when we see media and education in modern times.
