The Stoics identified strong emotions as our ultimate weakness; especially when we let them dictate our behavior. They’re toxic to eudaimonia and they’re at the root of all human suffering. Unfortunately, according to the Stoics, most of us are enslaved to passions—strong negative emotions such as irrational fear, grief, or anger. This is why so many of us are miserable, we’re far away from being a tower of strength, we’re far away from being at good terms with our ideal self. Our passions cause us to act far beneath of what we’re capable of.
