Musonius Rufus

Roman Stoic philosopher and the teacher of Epictetus. He insisted that philosophy is not a matter of words but of life — and that women, like men, should study it. He defended the marriage of equals, opposed the exposure of unwanted infants, and argued that "the good is taught by being lived." Exiled twice by emperors who found him inconvenient, once to a barren island in the Aegean. Most of his writing is lost; what survives comes through the lecture notes of his students. He is the closest thing Stoicism has to a quiet, stubborn schoolmaster.
