Got problems with your soul? These days, you’d see a psychotherapist. But, back in the day, it was the philosopher who’d help you optimize—they were the preferred physician of the soul. This book is about the philosophical roots of modern psychotherapy. Specifically, it outlines the connection between cognitive behavioral therapy (CBT) and Stoicism. Big Ideas we explore include being a warrior of the mind vs. a librarian of the mind, your highest human purpose, getting on good terms with your inner daimon, practicing the reserve clause and modeling your ideal sage.
