Friedrich Nietzsche was a brilliant philosopher, and one of his most interesting ideas was the doctrine of eternal return. According to this doctrine, everything that has ever happened will happen again and again, infinitely, in an endless cycle of time. At first glance, this idea may seem depressing or even nihilistic, but there is a certain beauty in the idea that our lives are not just random events but part of a larger, cosmic pattern.
Really enjoyed this; found the ideas timely and useful.
