We're going to have to pause and ask a few questions about what "Ethic, Ethics and Ethicists" is and are.
A Metaphysician asks: "What is the world made of? Does God exist? What is time?" Nouns, structures, grand cosmological theories.
An Ethicist asks: "How should a human being live? How do I build a soul capable of facing suffering? What kind of character must I forge to endure this life?" Verbs, actions, lived practice.
Jorges Luis Borges, the essayist and librarian had his issues with Nietzsche's Everlasting Return.
The Metaphysics of everlasting return made no sense to Borges, and he used the mathematics of Venn Diagrams to prove that everlasting return was a bunch of hokum.
But the Ethics of everlasting return, in conjunction with Nietzsche's perverse idea that now God was dead immortality was no longer a blundering hope it was an individual responsibility, all made perfect sense to Borges.
