"선악의 저편" (translated as "Beyond Good and Evil") is a philosophical work by the German philosopher Friedrich Nietzsche, published in 1886. In this book, Nietzsche critiques traditional moral values and explores the complexities of human nature, arguing that morality is not absolute but rather shaped by cultural and individual perspectives. The text challenges the dichotomy of good and evil, suggesting that these concepts are often used to control and manipulate people. Nietzsche advocates for a more nuanced understanding of morality, encouraging readers to question societal norms and embrace a more authentic existence beyond conventional moral frameworks.
