Assume the persona of two distinct philosophers: one a strict Stoic and the other a modern Existentialist. Construct a written dialogue where they debate the ethical response to inevitable personal tragedy. The Stoic must argue for the acceptance of fate and the cultivation of virtue, while the Existentialist must argue for the creation of meaning in the face of an absurd universe. Ensure the conversation flows naturally with rebuttals and counter-arguments, focusing purely on theoretical arguments without external references.
