"영원회귀" (Eternal Recurrence) is a philosophical concept suggesting that the universe and all events within it are eternally recurring in an infinite cycle. This idea posits that every moment in life will repeat itself endlessly, leading to questions about the nature of existence and the significance of individual actions. The concept is often associated with the philosopher Friedrich Nietzsche, who used it to explore themes of meaning and affirmation in life. Nietzsche challenged individuals to consider how they would live if they had to relive their lives repeatedly, encouraging a deeper reflection on choices and values.
