The quote "Time is a flat circle" is not from Friedrich Nietzsche, but rather from the television series "True Detective." It was spoken by one of the characters in the show and has become popularized in popular culture. Friedrich Nietzsche, the 19th-century philosopher, did not express this particular concept using those words.
However, Nietzsche did have his own ideas about time and its interpretation. He discussed the concept of eternal recurrence, which suggests that the universe and our lives repeat infinitely. According to Nietzsche's idea, every event that has occurred in the past will happen again and continue to recur in an unending cycle.
Nietzsche's concept of eternal recurrence raises questions about the nature of time, the meaning of existence, and the idea of eternal return. It challenges the notion of linear progress and presents a perspective where everything that has happened will happen again, without any fundamental changes.
While Nietzsche did not specifically use the phrase "Time is a flat circle," his thoughts on eternal recurrence are often associated with the cyclical nature of time. It's important to note that Nietzsche's philosophy is complex and nuanced, and the interpretation and understanding of his ideas require a more comprehensive study of his works.
