First of all it needs to be said that there are two different ways to approach this; from the definitional perspective and from the philosophical perspective. 'Stoicism' has two different meanings; it is both a way of life, a philosophy, and it has a common understanding that is used in everyday speech by ordinary folk, without reference to any famous Stoics like Marcus Aurelius.
