To Epictetus, all external events are determined by fate, and are thus beyond our control, but we can accept whatever happens calmly and dispassionately. Individuals, however, are responsible for their own actions which they can examine and control through rigorous self-discipline. Suffering arises from trying to control what is uncontrollable, or from neglecting what is within our power. As part of the universal city that is the universe, human beings have a duty of care to all fellow humans. The person who followed these precepts would achieve happiness.
EpictetusAnd have you not received faculties which will enable you to bear all that happens to you? Have you not received greatness of spirit? Have you not received courage? Have you not received endurance?
EpictetusGive yourself fully to your endeavors. Decide to construct your character through excellent actions and determine to pay the price of a worthy goal. The trials you encounter will introduce you to your strengths.
EpictetusOne that desires to excel should endeavor in those things that are in themselves most excellent.
EpictetusWhen therefore we are hindered, or disturbed, or grieved, let us never attribute it to others, but to ourselves; that is, to our own principles. An uninstructed person will lay the fault of his own bad condition upon others. Someone just starting instruction will lay the fault on himself. Some who is perfectly instructed will place blame neither on others nor on himself.
