Friedrich Nietzsche was a German philosopher who lived between 1844 and 1900, and his proposal on eternal recurrence was one of his most discussed works. The concept states that the world is eternally self-destructive, then self-creative, over time. He radicalizes the Christian concept of eternity and combines it with simple reasoning to arrive at an innovative concept. This article will discuss in detail what eternal recurrence is and the implications of such a concept on free minds, and whether or not adopting such a belief will improve a person's life. The article will then propose a response to the criticisms of Nietzsche's proposition. The text to use is the second edition of “Existentialism: Fundamental Writings” by Charles Guignon and Derk Pereboom. This book offers a good rudimentary synopsis of the four main proponents of existentialism: Nietzsche, Heidegger, Sartre and Kierkegaard, with excerpts from Husserl and Hegel aimed at giving a better explanation of the origin of existentialism. The author offers a simplified explanation of the various philosophical concepts of the philosophers mentioned above, making it easier to understand than would have been possible if one had read the original works. The book's specific area of ​​focus is that which covers Nietzsche's Gay Science, as it offers insight into his concept of eternal recurrence. The purpose of this article is to provide a detailed explanation of Nietzsche's concept of eternal recurrence and then move on to determine whether such a concept enhances the life of a free spirit or whether it does not. Before determining whether the concept has a positive outcome or not, it is important to provide a detailed overview of life events, and even manage to draw some positives from these experiences. Those who oppose this concept do so on a basic level, without truly understanding the impact of eternal recurrence on a free mind. Such arguments are made on a superficial interpretation, without taking into account; the fact that such an approach involves all of a person's movements throughout their life, as they seek to have the most fulfilling life experience, regardless of their wealth or social status. Ultimately, taking such an approach depends on personal perception, as some people might view the opportunity to relive every moment of their life as an opportunity not to be missed, while others might see it as an unnecessary burden.
