 This distinction between what is internal to the sphere of volition and what is external to it is the foundation of Epictetus’s system of value. What is ultimately worth having, the “good of humankind,” consists in “a certain disposition of one’s volition” (1.8.16). More explicitly, this disposition is the condition of virtue, the proper expression of our rational nature, in which we not only act correctly and on the basis of knowledge, but also recognize our kinship to god and witness with joy god’s orderly management of the universe.
