The "Handbook" focuses on the individual, and the main question is how they can achieve lasting happiness and undisturbed inner peace. According to Epictetus, there are things that are within our control and things that are not; it is preferable to accept what we cannot change. An ideal life would be as independent as possible from the external world: endure and abstain, that is the message of the work. In a straightforward manner, avoiding theoretical abstractions and obscure terminology, Epictetus addresses his fellow human beings with great directness and seeks to influence their thinking; he wants to shape ethical personalities that will constantly strive for good to triumph over evil within them.
