Why did I love this book?
Cognitive Behavior Therapy is premised on the belief that our thoughts are at the root of our negative feelings, and to alter those feelings, we need to alter our thoughts. The connection between reason and emotion can be traced back to Stoicism. Hence it is no surprise that the late Dr. Albert Ellis, the developer of the very similar Rational Emotive Behavior Therapy, used to have a quote from the Stoic philosopher Epictetus on his webpage. In addition, the Cognitive Distortions which form the heart of CBT can mostly be found in The Art of Thinking (1662) by Antoine Arnauld and Pierre Nicole.
