Stoics have nothing against existentialism quotes. While both come from the Western philosophy branch, existentialism focuses on the idea that existence is subjective. Every one of us will have a different experience while living in the world, and thus we will have to choose different paths. Where stoics try to view the world from a more positive and realistic perspective, existentialists take a more pessimistic stance. Existential quotes focus on the anxiety and the idea that you are in charge of your own life, even if it is absurd and dreadful.
