No man is free who is not master of himself.
Freedom, to Epictetus, was not political. It was internal. Even as a slave, he considered himself freer than many Roman nobles who were imprisoned by ambition, fear, or anger. His teachings focused on temperance, reminding his students that true liberty comes from self-discipline.
Master your desires, or they will master you.
