That One Should Disdain Hardships
Musonius Rufus, a Stoic philosopher from the first century C.E., was one of the most influential teachers of his era in imperial Rome. Alongside Stoics like Seneca, Epictetus, and Marcus Aurelius, he emphasized ethics in action, displayed in all aspects of life. Merely learning philosophical doctrine and listening to lectures, they believed, will not do one any good unless one manages to interiorize the teachings and apply them to daily life. In Musonius Rufus's words, "Philosophy is nothing else than to search out by reason what is right and proper and by deeds to put it into practice."
