Take back the source of the past 20th century Western trend, we can't find a huge shadow to cover the whole era, this is Nietzsche - a poet, a drifter, a sincere philosoprie who is crazy for thought, a kill Dead God and smashed the hero of all idols. One Nietzsche is not a college-style philosopher. He is not even a scholar's identity, but first engaged in philosophical activities as a sincere person. However, the philosophy of Nietzsche is filled with a rare philosophical temperament, there is a small mysteriousness of the rejuvenation and self-deception, this is really difficult. Sincerely mean the investment in all life, sincere thought is "a passionate soul history", which is full of "the boost and vibration of life burning in the enthusiasm of thought." The fact is that "Life is meant to us, all of us, together with our all, constantly cultivating the bright and fire" philosophy is not a profession, not hobbies, but Nietzsche's full life. Nietzsche always touches the fundamental issues of life and era, no concealment, no fashion, but not fabricated, its thoughts or brilliance, or absurd, but there is no exception is - sincerity! A sincere life explore may make mistakes, but his attitude towards life is correct; a sleek course may not make mistakes, but his attitude towards life is the biggest mistake. So, Nizi said scorn: "Even if I walk, I still walk on the top of their head." Ni Nie is a pioneer in modern Western trend, and his universal impact is mainly concentrated in four aspects: first, "God died" Nietzsche with its unique keen and courage, the first to announce the fact that Christian beliefs bankrupt, and issued the "revaluation of all values", which reveals the priority of the value vacuum faced by Europeans. The 20th century has got more broad recognition, which has triggered two major themes in modern Western literature and philosophy: the absurdity of people and the freedom of people, the liberation of humanity and unlimited possibilities. Second, Nietzsche has further got a conclusion of the relativity of all traditional value, emphasizing individual first, self-realization. The discussion of modern Western thought circles on the "alienation" problem of modern people, the earliest to Nietzsche. Third, Nietzsche first reveals the limitations of scientific rationality, and he is the first person who clearly reveals unconscious fields and detailed analysis. The strong orthodentist trend in the field of modern Western cultural fields, such as modern literature art, Freud's mental analysis, phenomenological movement, presence philosophy, Nietzsche is the nose of the mountain. Fourth, Nietzsche is one of the founders of modern Western philosophical people. He clearly advocates that philosophy is the main purpose of exploring life, and his views of human nature, with human beypo, which is very modern. Therefore, it can be said without exaggeration. If you don't understand Nietzsche, it is impossible to understand the modern Western trend. After San Niqi did not leave a school named by his name, he influentially infiltrated in many philosophical geography in modern Western. The main problem proposed by Nietzsche is: How do people re-establish the meaning of life in a full-collapse of traditional values? His answer can be summed up to three directions: 1. Loosing rationality and morality for the suppression of life instinct, so that life is healthy; second, the transcendence of people, the creator of spiritual cultural value; three, with aesthetic life Attitude replaces the scientific and ethical life attitude.
