Nietzsche, a great philosopher, deeply influenced the development of postmodern philosophy, especially in existentialism and postmodernism, and Nietzsche's philosophical views played a decisive role.
However, Nietzsche's life was lonely and emotionally incomprehensible, which eventually led him to enter a brothel and contract syphilis. So, who made him into the brothel?

Behind Nietzsche's sad emotional entanglement, we need to start from the environment in which he lives.
Nietzsche was born in 1844 and his father died when he was five years old, and Nietzsche lived in a family without a man, and he had to face his mother and sister alone, which may be the root of Nietzsche's tragic life.
Nietzsche's youth was gray, he had no more playmates, only a sister two years younger than him, and his sister had cast a lifelong "spell" on him that could not be relieved—in the book "Me and My Sister", Nietzsche was very frank about how his sister used his body to pleasure.
Although such a thing made Nietzsche feel guilty, it was inseparable from the insurmountable feeling that his sister gave him. In this way, Nietzsche began to live in an unbearable emotional entanglement for ordinary people from childhood, and on the one hand, he had to take into account rational emotions, but on the other hand, he could not live without his sister.
Later, the sister married a man. Nietzsche was extremely reluctant and chose not to appear at his sister's wedding. Later, Nietzsche wrote to his sister in an attempt to snatch her back from the man.
In a letter that Nietzsche wrote to his sister, we can find the answer that Nietzsche's feelings for his sister are sincere. In his letter, he wrote: "I can have a woman who is worthy of respect and makes me yearn for. But the best thing is to get back to my favorite Loma (Loma is Nietzsche's affectionate name for his sister), who is a very happy and suitable person for philosophers. ”
Nietzsche and his sister
Nietzsche's abnormal relationship with her sister doomed Nietzsche's lifelong marriage to failure. His love and hatred for his sister directly leads him to be between doubt and longing for other women. He was obsessed with young women, hated older women, and he even thought old women were a kind of monster.
Therefore, Nietzsche only favored young women. During his time at the University of Leipzig, he fell in love with an actress who frantically wrote love poems to each other, but how could a young woman dare touch such a strange thing? So Nietzsche was rejected. This was Nietzsche's first love. It can be seen that Nietzsche, based on normal people, does not know much about the way men and women get along.
For example, in 1876, when Nietzsche was teaching at the University of Basel in Switzerland, he met a Dutch girl, and the people also rejected him, until everyone was married, he did not understand why people were unwilling to be good to him, and wondered" How can a wise woman marry a man who is not a philosopher." ”
Nietzsche can be said to be hopelessly obsessed with young girls, and at the age of 40, he fell in love with a girl 18 years younger than him, named Salome. Nietzsche's obsession with Salome reached the point of madness, and he described Salome as follows: "She is like a mountain, especially thinking of his freedom, which blooms in a dense jungle of Bourgeois; the pace of her Roman imperial gang, as if nothing could stand in her way..."
But Salome did not have so many feelings for Nietzsche, and she may have only been a friend of Nietzsche, and fell in love with Nietzsche over and over again for several years in the case of emotional half-pushing. In recent years, Salome only wants to have spiritual contact with Nietzsche, and does not intend to develop physical contact with Nietzsche.
In the past few years, Nietzsche has also been deeply affected by the lives of his mother and sister, in a clumsy state of emotional expression, not knowing how to express emotions naturally, and once he meets a woman, he will become shy and sensitive. Later, as a last resort, Salome severed ties with Nietzsche. Nietzsche suffered too much of a blow and fell into a state of madness.
Finally, Nietzsche entered the brothel.
On the surface, Nietzsche's entry into the brothel was caused by Salome, but in fact, Nietzsche's doing such a crazy thing has nothing to do with his own sister.
Nietzsche described this in his book My Sister and Me, in which Nietzsche believed that "every woman has a prostitute in her heart." ”
This sentence shows that Nietzsche was extreme to love, and his extreme has existed since childhood. His own sister tortured Nietzsche physically from an early age, and Nietzsche tangled in love and hate to look at women and love, and he mistakenly thought that love was a physical feeling. He even hated Plato's doctrine, which he understood as an almost extreme view.
Nietzsche believed that love was the product of abstinence.
He believed that so-called love was nothing more than the most primitive impulse between men and women, but Christianity suppressed this nature of such people, so that people had to satisfy this impulse by other means, and in the process of repression a thing called love was produced.
Nietzsche had this idea because when he was young, just when the hormones were strong, his sister gave him these feelings, and he vaguely believed that this was love, but in fact, he or his sister felt the most, just physical pleasure. This way of getting along between men and women gives Nietzsche a vague understanding of love. So much so that Nietzsche was madly infatuated with young girls, and for old women, he thought of monsters. Such thinking is obviously facilitated by the basic starting point of the flesh.
But Nietzsche mistakenly believed that so-called love was to have physical contact with a young woman, and for Nietzsche, who longed for love, after several failed love attempts, the most effective and direct love was probably only a brothel. And it is in line with Nietzsche's understanding that unbridled entanglement is the craziest love.
It was in this case that Nietzsche was infected with syphilis, and he was also proud and ecstatic about syphilis, and he thought that contracting syphilis was a kind of self-liberation, so under the action of syphilis, Nietzsche's thinking began to go wild, and he wrote "The Death of God" with perseverance that ordinary people could not imagine, and these masterpieces were completed in his almost mad state.
It wasn't until January 3, 1889, that Nietzsche saw a man whipping a horse in the square, and he ran up to hold the horse by the neck and said, "O my suffering brother!" Then he fell to the ground and never got up. Not long after, Nietzsche died, with his loneliness and the unbearable pain of syphilis.
