If you had to live this exact life again, infinitely — would you say yes?

Sophia Nietzsche Eternal Return Reflection

Nietzsche's thought experiment of the Eternal Return asks the most demanding question possible: if you had to relive your exact life — every joy and every suffering — for eternity, would you embrace it? It's not a metaphysical claim. It's a diagnostic tool for how you're living now.

Quick Summary

What it is: Nietzsche's most demanding thought experiment: if you had to relive every moment forever, would you say yes?
What it helps with: Regret-heavy hindsight, life affirmation deficit, choice ownership fear, what-if spiral.
How to use it: Open Sophia → Write how this idea applies to one situation in your day → Sit with what you wrote for a quiet minute
