Living a life without having thoughts or even trying to make sense of the world that is constantly evolving would not be a life worth living. In order to have a fulfilling life, people must have developed thoughts about the way they are living their lives. Knowledge gained through reasoning could make people good, wise, and happy. Epictetus, a Stoic philosopher, would argue that people could never fail to be happy as long as they learn to differentiate what is in human power and what is not. The only way to differentiate what is in human power and what is not is through reasoning; throughout Epictetus’ discourses, he elaborates on how to differentiate these things and how people should reason in a manner that will bring them happiness.
