The Stoics Invented CBT

While many modern psychological approaches have come and gone, Cognitive Behavioral Therapy (CBT) is one of the few that gives people a clear way to catch bad thought patterns and do something about them. Its core idea shows up much earlier in the Stoics.

CBT is among the most well-researched and effective forms of therapy available today, with countless studies demonstrating its efficacy for treating depression, anxiety, and other conditions¹. Yet long before modern psychology existed, Stoic philosophers like Epictetus, Seneca, and Marcus Aurelius were advocating remarkably similar techniques.

Epictetus, a former slave who became one of the most influential Stoic philosophers, wrote in his Enchiridion: “Men are disturbed not by things, but by the views which they take of them.”² That idea is basically the move both Stoicism and CBT make: look at the interpretation, not just the event.

Compare this to the CBT concept of cognitive distortions, where therapists help patients identify and challenge irrational thought patterns. When Aaron Beck developed CBT in the 1960s, he was essentially rediscovering what the Stoics had been teaching since the 3rd century BCE³.

Therapy is much more normal to talk about now, which is mostly good. But whether it helps still depends a lot on the therapist and whether you’re willing to do the work outside the session. The approaches that have helped me most were structured and gave me something to practice—much like Stoic exercises.

For many people, therapy gives them a place to sort through what is actually going on. Sometimes it helps just to have someone pay close attention and not flinch. But the Stoics would remind us that external support, while helpful, is only part of the equation.

Both CBT and Stoicism start from the same place: we can’t control external events, but we can examine our interpretations and responses. Marcus Aurelius put it well in his Meditations: “You have power over your mind—not outside events. Realize this, and you will find strength.”⁴

When I was introduced to CBT by a therapist nearly a decade ago, it inadvertently led me to discover Stoicism. The therapist taught me practical skills like articulating my feelings clearly to others and recognizing patterns in my thoughts. She also recommended several CBT books that proved more valuable than our sessions themselves.

In practice, both CBT and Stoicism involve:

1. Identifying automatic negative thoughts
2. Examining the evidence for and against these thoughts
3. Developing more balanced perspectives
4. Acting in accordance with these healthier viewpoints

Seneca advised this type of cognitive reframing when he wrote: “We suffer more often in imagination than in reality.”⁵ This mirrors the CBT technique of reality-testing catastrophic thoughts.

The next time you feel upset about something, try this Stoic-inspired CBT exercise: Ask yourself, “Is this worth being disturbed about? What evidence supports my interpretation? What alternative views might be more accurate or helpful?” Even that brief pause can keep a thought from dragging you around.

Practice it regularly and you’ll probably start noticing the thought a little earlier, before it turns into a whole spiral.⁶
