The Birth of Tragedy is Nietzsche's first work and the birthplace of Nietzsche's philosophy. Nietzsche said that the theme of this book is actually "How did the Greeks deal with pessimism-how did they overcome it?" He thinks Schopenhauer is completely wrong, and the Greek tragedy just shows that Greeks are not pessimists. The Greeks did not pin their ideals on tragedy, and did not use tragic art to save their lives. There is a contradiction between Dionysus and Apollo in Greek tragedy, which is absent, so it is "nihilism". It originated from Socrates' decadent school, which opposed the degenerate instinct of life with humble ambition, denied life, and then gave up on itself, wearied the world, and longed for eternal life and happiness on the other side.

Contrary to nihilism, Nepal adopts Dionysian spirit to affirm life, pain, sin and life itself. In the first part of Zarathustra, he opposes nihilistic values by opposing "transcendental theorists". And use "superman" to object. He said in a tit-for-tat manner, "Superman is the meaning of the earth", and he should turn his eyes from the sky to the ground and from the other shore to this shore-"Be loyal to the earth and don't trust those who talk about the hope of a super-large earth!"

Therefore, Nietzsche is not an idealist. He asked people to turn their ideals back to reality and base themselves on the earth, "so that the earth can belong to Superman one day". To this end, Nietzsche wanted to re-evaluate all the values.

Understanding and affirming reality is necessary for the strong, just as the weak become timid and escape from reality when they are motivated, that is to say,' ideal' is also necessary for the weak ... The weak do not realize that decadence needs lies, and lies are one of their living conditions. "

Therefore, Nietzsche's philosophy is the philosophy of the strong, the philosophy of loyalty to the earth, the philosophy of affirming life and the philosophy of anti-idealism.
