CBT and Its Stoic Roots
Cognitive behavioural therapy is the most widely used psychological treatment in the world. Its founding claim — that emotional disturbance is caused not by events but by the beliefs and judgements we hold about them — was stated precisely by Epictetus in the first century.
This is not a loose parallel. Albert Ellis, who developed rational-emotive behaviour therapy in the 1950s, cited Epictetus directly. Aaron Beck, who developed CBT, drew on the same tradition. The mechanism both were describing had already been mapped, in philosophical terms, two thousand years before the clinical trials.
The Shared Claim
Epictetus opens the Enchiridion with a division that CBT practitioners would recognise immediately: some things are in our power, some are not. Our judgements and opinions are in our power; external events are not.
The therapeutic implication is the same in both traditions. If distress is caused by judgements rather than events, then examining and revising those judgements is the path to relief. CBT calls this cognitive restructuring. The Stoics called it philosophy.
What This Pillar Covers
The articles here trace the connection between ancient Stoic philosophy and modern psychological practice — not as intellectual history, but as a practical account of a mechanism that has been rediscovered in two very different vocabularies.
Understanding where the idea came from does not make it more true. But it does make it harder to dismiss as self-help.
The Evening Review
The Stoics practiced daily examination of judgements — the same cognitive audit that CBT formalises as a homework exercise. Three questions, five minutes, before bed.
