We would like to thank our agent Tisse Takagi for encouragement and very helpful feedback when we first undertook this project. Many thanks to the entire team at The Experiment, especially Batya Rosenblum, our editor, for her patience, thoroughness, and many constructive comments. We also appreciate Taya Kogan’s reading and input on the manuscript. In addition, we thank our students at the annual Stoic Camp in New York and Stoic School in Rome, who have been our willing test subjects for ideas on how to teach and practice Stoicism. We hope they have benefited from the process as much as we have. We also wish to acknowledge our intellectual debt to Larry Becker, whom Massimo has had the fortune to call his friend. Larry passed away recently, but his contributions to modern Stoicism continue to be an inspiration for all students and practitioners of the philosophy.
