For the last four years, two titans and respected leaders in their fields have met monthly for lunch to talk about their work, their lives, and the books they are reading. When Aaron Beck, MD, professor of Psychiatry, and Martin Seligman, PhD, professor of Psychology, discuss their professional endeavors, the conversation centers on the mind and how to help people lead lives that are happy, productive and fulfilling. Beck, 92, is a psychiatrist and the father of cognitive therapy. Seligman, 71, is a psychologist and the founder of positive psychology. Philadelphia Inquirer reporter, Art Carey recently sat in on one of their monthly conversations and reports that they are usually frank and wide-ranging. Carey chronicles their conversation in his column, noting that the two "deepen each other's understanding, spar, pivot and challenge, as their searching exchanges weave new intellectual connections and stimulate surprising imaginative leaps."
