In this article, the main arguments of Friedrich Nietzsche on art, tragedy and the affirmation of the existence will be dealt with by emphasizing his ideas in his work The Birth of Tragedy. In this context, Nietzsche’s views on aesthetics and philosophy of art will be demonstrated in relation to existentialism. In this work, Nietzsche examines the Apollo - Dionysus controversy and how the art of tragedy emerged. He criticizes his time because of caring about the Apollonian more and neglecting the Dionysian or the emotions. For him, it is important to balance the two. Both the Apollonian and the Dionysian are necessary in the creation of art. Nietzsche sees Euripides as the murderer of art because by following Socrates he only focuses on knowledge and the individual and eliminates the elements that are crucial for Dionysian experience. Thus Euripides takes Dionysus away from tragedy, and he destroys the balance between Dionysus and Apollo. According to Nietzsche, art is the only force that can save us from anxiety of existence and this controversy, which is in life and in existence itself. His idea of loving life, saying yes to life and living creatively means affirming life, ourselves and our existence. Therefore Nietzsche sees the art as an answer to nihilism.
