Søren Aabye Kierkegaard; Copenhagen (1813 - 1855) was a Danish philosopher, theologian, poet, and social critic, widely considered the first existentialist philosopher. Throughout his career, he wrote critical texts on organized religion, Christianity, morality, ethics, psychology, and philosophy of religion, showing a particular penchant for figures of speech such as metaphor, irony, and allegory. The work "The Diary of a Seducer" portrays what Kierkegaard understands as the aesthetic way of life, characterized by romantic and sophisticated hedonism. The seducer is an individual who chooses to immerse himself in passion, in the contradictions of amorous existence. He chooses pleasure as the purpose of life, personally enjoying the aesthetic and aesthetically enjoying his own personality.
