Cognitive Behavioural Therapy (CBT) and its main branch, Rational Emotive Behavioural Therapy (REBT), are rooted in Stoic philosophy. As Epictetus said, “Men are disturbed not by things, but by the view which they take of them.”
In our modern world, that might look like thinking, “They shouldn’t speak to me like that,” or “If I make a mistake, they’ll think I’m incompetent.” These thoughts often lead to stress, frustration, or self-doubt.
CBT/REBT helps you notice and challenge these beliefs, building psychological flexibility — the ability to see situations from a broader perspective. With practice, this shift can help you stay calm under pressure, communicate more clearly, and make confident decisions without being driven by fear or perfectionism.
