Young Jean Baudrillard comes to his mistress in Paris. - Jean, baby, let's do Pentabase today! - What is pentabase? - How?! You don't know what pentabase is?! - The mistress is indignant and throws him out. Baudrillard came to his wife. - My dear, shouldn't we make a pentabase? -Who are you taking me to?! His wife shouts and throws him out the door. Baudrillard goes to a brothel. - Mademoiselle, here's a hundred francs for you. Show me the Pentabase. - Pentabase?! A hundred francs?! You are crazy! - The prostitute replies and walks away. Baudrillard thought. It turns out that everyone knows what Pentabasis is, everyone knows who can be offered and who can't, how much it should cost, but no one can explain what it is. "Curious," Jin thinks. - The sign exists, circulates in society, regulates behavior and relationships, but its reference remains inaccessible. Is it really Molly simulacrum? He remembers his old aunt, who in her youth was a famous Parisian courtesan. Comes to her: - Aunt! You know what Pentabase is, right? Auntie smiles dreamily: - Oh, Jean fantasizes and he's dead. Baudrillard sits in silence for a long time, then takes out a pad and writes: "Pentabase should no longer exist. He puts himself forward as a model, creating the real without source and reality. This is a hyperpentabase. This is how the book "Simulacra and Simulation" appeared. And Baudrillard never found out what a pentabase was. However, now it no longer matters: the Pentabase never existed.
