Nietzsche's thought experiment: would you live your life over and over again?
The Eternal Return (or Eternal Recurrence) is a thought experiment proposed by Friedrich Nietzsche: imagine that you must live your life exactly as it has been, in every detail, over and over for eternity. Every joy and every suffering, every triumph and every failure — repeated infinitely. Nietzsche presented this not as a scientific claim but as the ultimate test of how you feel about your life. If the idea fills you with despair, something needs to change. If you can embrace it, you have achieved amor fati — love of your fate.

FAQ
What is Nietzsche's Eternal Return?
The Eternal Return is Nietzsche's thought experiment: imagine that you must live your entire life — every moment, every detail — over and over again for eternity. It is not a claim about how the universe works, but a philosophical test. How you react to this idea reveals how you truly feel about your life.
What is the point of the Eternal Return?
The point is to confront how you feel about your life. If the idea of reliving it forever fills you with horror, it means there are things you want to change. If you can say yes to it — even welcome it — you have achieved what Nietzsche called amor fati (love of fate). It is a tool for evaluating whether you are truly living the life you want.
Is the Eternal Return meant literally?
Most philosophers interpret the Eternal Return as a thought experiment, not a literal claim about the universe. Nietzsche used it as a psychological and existential test: a way to measure the quality of your life and your ability to affirm it completely.
