Modern psychology (CBT) is built on a Stoic idea: “It’s not things that upset us, but our opinions about things.”
Stoicism doesn’t tell you to repress feelings. It tells you to examine them, to look at the beliefs behind them. If the belief is false (“this event ruins my life”), you correct it; if it’s true, you accept the feeling without letting it take over.
The Stoics called destructive emotions “passions,” but they also recognized healthy ones, like rational joy, caution, and goodwill. The goal isn’t emotional numbness, it’s clarity and alignment with reason and nature.
So, far from emotional blindness, Stoicism actually inspired the same kind of introspection that modern psychology promotes, just with a different vocabulary.
I would encourage you to read about CBT’s history and it’s influence on more modern psychology techniques. It’s likely that you are representing the Stoicism you commonly read about these days, on reddit, youtube and even on some books that take some liberties on translating it or do a bad job of it (it’s hard…). Most modern sources absolutely suck. A good translation from the original greek sources of Epictetus is very hard to come by.
